The Brussels-Capital Region is located in the central portion of the country and is a part of both the French Community of Belgium and the Flemish Community, but is separate from the Flemish Region (within which it forms an enclave) and the Walloon Region. + +Brussels is the most densely populated region in Belgium, and although it has the highest GDP per capita, it has the lowest available income per household. The Brussels Region covers , a relatively small area compared to the two other regions, and has a population of over 1.2 million. The five times larger metropolitan area of Brussels comprises over 2.5 million people, which makes it the largest in Belgium. It is also part of a large conurbation extending towards the cities of Ghent, Antwerp, and Leuven and the province of Walloon Brabant, in total home to over 5 million people. + +Brussels grew from a small rural settlement on the river Senne to become an important city-region in Europe. Since the end of the Second World War, it has been a major centre for international politics and home to numerous international organisations, politicians, diplomats and civil servants. Brussels is the de facto capital of the European Union, as it hosts a number of principal EU institutions, including its administrative-legislative, executive-political, and legislative branches (though the judicial branch is located in Luxembourg, and the European Parliament meets for a minority of the year in Strasbourg). Because of this, its name is sometimes used metonymically to describe the EU and its institutions. The secretariat of the Benelux and the headquarters of NATO are also located in Brussels. + +As the economic capital of Belgium and a top financial centre of Western Europe with Euronext Brussels, Brussels is classified as an Alpha global city. It is also a national and international hub for rail, road and air traffic, and are sometimes considered, together with Belgium, as the geographic, economic and cultural crossroads of Europe. The Brussels Metro is the only rapid transit system in Belgium. In addition, both its airport and railway stations are the largest and busiest in the country. + +Historically Dutch-speaking, Brussels saw a language shift to French from the late 19th century. Nowadays, the Brussels-Capital Region is officially bilingual in French and Dutch, although French is the majority language and lingua franca with over 90% of the inhabitants being able to speak it. Brussels is also increasingly becoming multilingual. English is spoken as a second language by nearly a third of the population and many migrants and expatriates speak other languages as well. + +Brussels is known for its cuisine and gastronomic offer (including its local waffle, its chocolate, its French fries and its numerous types of beers), as well as its historical and architectural landmarks; some of them are registered as UNESCO World Heritage Sites. Principal attractions include its historic Grand-Place/Grote Markt (main square), Manneken Pis, the Atomium, and cultural institutions such as La Monnaie/De Munt and the Museums of Art and History. Due to its long tradition of Belgian comics, Brussels is also hailed as a capital of the comic strip. + +Toponymy + +Etymology +The most common theory of the origin of the name Brussels is that it derives from the Old Dutch , or , meaning ( / ) and ( / / ) or . Saint Vindicianus, the Bishop of Cambrai, made the first recorded reference to the place in 695, when it was still a hamlet. The names of all the municipalities in the Brussels-Capital Region are also of Dutch origin, except for Evere, which is Celtic. + +Pronunciation +In French, is pronounced (the x is pronounced , like in English, and the final s is silent) and in Dutch, is pronounced . Inhabitants of Brussels are known in French as (pronounced ) and in Dutch as (pronounced ). In the Brabantian dialect of Brussels (known as Brusselian, and also sometimes referred to as Marols or Marollien), they are called Brusseleers or Brusseleirs. + +Originally, the written x noted the group . In the Belgian French pronunciation as well as in Dutch, the k eventually disappeared and z became s, as reflected in the current Dutch spelling, whereas in the more conservative French form, the spelling remained. The pronunciation in French only dates from the 18th century, but this modification did not affect the traditional Brussels usage. In France, the pronunciations and (for ) are often heard, but are rather rare in Belgium. + +History + +Early history + +The history of Brussels is closely linked to that of Western Europe. Traces of human settlement go back to the Stone Age, with vestiges and place-names related to the civilisation of megaliths, dolmens and standing stones (Plattesteen near the Grand-Place/Grote Markt and Tomberg in Woluwe-Saint-Lambert, for example). During late antiquity, the region was home to Roman occupation, as attested by archaeological evidence discovered on the current site of Tour & Taxis, north-west of the Pentagon (Brussels' city centre). Following the decline of the Western Roman Empire, it was incorporated into the Frankish Empire. + +According to local legend, the origin of the settlement which was to become Brussels lies in Saint Gaugericus' construction of a chapel on an island in the river Senne around 580. The official founding of Brussels is usually said to be around 979, when Duke Charles of Lower Lorraine transferred the relics of the martyr Saint Gudula from Moorsel (located in today's province of East Flanders) to Saint Gaugericus' chapel. When King Lothair II appointed the same Charles (his brother) to become Duke of Lower Lotharingia in 977, Charles ordered the construction of the city's first permanent fortification, doing so on that same island. + +Middle Ages +Lambert I of Leuven, Count of Leuven, gained the County of Brussels around 1000, by marrying Charles' daughter. Because of its location on the banks of the Senne, on an important trade route between Bruges and Ghent, and Cologne, Brussels became a commercial centre specialised in the textile trade. The town grew quite rapidly and extended towards the upper town (Treurenberg, Coudenberg and Sablon/Zavel areas), where there was a smaller risk of floods. As it grew to a population of around 30,000, the surrounding marshes were drained to allow for further expansion. Around this time, work began on what is now the Cathedral of St. Michael and St. Gudula (1225), replacing an older Romanesque church. In 1183, the Counts of Leuven became Dukes of Brabant. Brabant, unlike the county of Flanders, was not fief of the king of France but was incorporated into the Holy Roman Empire. + +In the early 13th century, the first walls of Brussels were built, and after this, the city grew significantly. To let the city expand, a second set of walls was erected between 1356 and 1383. Traces of these walls can still be seen, although the Small Ring, a series of boulevards bounding the historical city centre, follows their former course. + +Early modern + +In the 15th century, the marriage between heiress Margaret III of Flanders and Philip the Bold, Duke of Burgundy, produced a new Duke of Brabant of the House of Valois, namely Antoine, their son. In 1477, the Burgundian duke Charles the Bold perished in the Battle of Nancy. Through the marriage of his daughter Mary of Burgundy (who was born in Brussels) to Holy Roman Emperor Maximilian I, the Low Countries fell under Habsburg sovereignty. Brabant was integrated into this composite state, and Brussels flourished as the Princely Capital of the prosperous Burgundian Netherlands, also known as the Seventeen Provinces. After the death of Mary in 1482, her son Philip the Handsome succeeded as Duke of Burgundy and Brabant. + +Philip died in 1506, and he was succeeded by his son Charles V who then also became King of Spain (crowned in the Cathedral of St. Michael and St. Gudula) and even Holy Roman Emperor at the death of his grandfather Maximilian I in 1519. Charles was now the ruler of a Habsburg Empire "on which the sun never sets" with Brussels serving as one of his main capitals. It was in the Coudenberg Palace that Charles V was declared of age in 1515, and it was there in 1555 that he abdicated all of his possessions and passed the Habsburg Netherlands to King Philip II of Spain. This palace, famous all over Europe, had greatly expanded since it had first become the seat of the Dukes of Brabant, but it was destroyed by fire in 1731. + +In the 16th and 17th centuries, Brussels was a centre for the lace industry. In addition, Brussels tapestry hung on the walls of castles throughout Europe. In 1695, during the Nine Years' War, King Louis XIV of France sent troops to bombard Brussels with artillery. Together with the resulting fire, it was the most destructive event in the entire history of Brussels. The Grand-Place was destroyed, along with 4,000 buildings—a third of all the buildings in the city. The reconstruction of the city centre, effected during subsequent years, profoundly changed its appearance and left numerous traces still visible today. + +Following the Treaty of Utrecht in 1713, Spanish sovereignty over the Southern Netherlands was transferred to the Austrian branch of the House of Habsburg. This event started the era of the Austrian Netherlands. Brussels was captured by France in 1746, during the War of the Austrian Succession, but was handed back to Austria three years later. It remained with Austria until 1795, when the Southern Netherlands were captured and annexed by France, and the city became the capital of the department of the Dyle. The French rule ended in 1815, with the defeat of Napoleon on the battlefield of Waterloo, located south of today's Brussels-Capital Region. With the Congress of Vienna, the Southern Netherlands joined the United Kingdom of the Netherlands, under King William I of Orange. The former Dyle department became the province of South Brabant, with Brussels as its capital. + +Late modern + +In 1830, the Belgian Revolution began in Brussels, after a performance of Auber's opera La Muette de Portici at the Royal Theatre of La Monnaie. The city became the capital and seat of government of the new nation. South Brabant was renamed simply Brabant, with Brussels as its administrative centre. On 21 July 1831, Leopold I, the first King of the Belgians, ascended the throne, undertaking the destruction of the city walls and the construction of many buildings. + +Following independence, Brussels underwent many more changes. It became a financial centre, thanks to the dozens of companies launched by the Société Générale de Belgique. The Industrial Revolution and the opening of the Brussels–Charleroi Canal in 1832 brought prosperity to the city through commerce and manufacturing. The Free University of Brussels was established in 1834 and Saint-Louis University in 1858. In 1835, the first passenger railway built outside England linked the municipality of Molenbeek-Saint-Jean with Mechelen. + +During the 19th century, the population of Brussels grew considerably; from about 80,000 to more than 625,000 people for the city and its surroundings. The Senne had become a serious health hazard, and from 1867 to 1871, under the tenure of the city's then-mayor, Jules Anspach, its entire course through the urban area was completely covered over. This allowed urban renewal and the construction of modern buildings of Haussmann-esque style along grand central boulevards, characteristic of downtown Brussels today. Buildings such as the Brussels Stock Exchange (1873), the Palace of Justice (1883) and Saint Mary's Royal Church (1885) date from this period. This development continued throughout the reign of King Leopold II. The International Exposition of 1897 contributed to the promotion of the infrastructure. Among other things, the Palace of the Colonies, present-day Royal Museum for Central Africa, in the suburb of Tervuren, was connected to the capital by the construction of an grand alley. + +Brussels became one of the major European cities for the development of the Art Nouveau style in the 1890s and early 1900s. The architects Victor Horta, Paul Hankar, and Henry van de Velde were known for their designs, many of which survive today. + +20th century + +During the 20th century, the city hosted various fairs and conferences, including the Solvay Conference on Physics and on Chemistry, and three world's fairs: the Brussels International Exposition of 1910, the Brussels International Exposition of 1935 and the 1958 Brussels World's Fair (Expo 58). During World War I, Brussels was an occupied city, but German troops did not cause much damage. During World War II, it was again occupied by German forces, and spared major damage, before it was liberated by the British Guards Armoured Division on 3 September 1944. Brussels Airport, in the suburb of Zaventem, dates from the occupation. + +After World War II, Brussels underwent extensive modernisation. The construction of the North–South connection, linking the main railway stations in the city, was completed in 1952, while the first premetro (underground tram) service was launched in 1969, and the first Metro line was opened in 1976. Starting from the early 1960s, Brussels became the de facto capital of what would become the European Union (EU), and many modern offices were built. Development was allowed to proceed with little regard to the aesthetics of newer buildings, and numerous architectural landmarks were demolished to make way for newer buildings that often clashed with their surroundings, giving name to the process of Brusselisation. + +Contemporary +The Brussels-Capital Region was formed on 18 June 1989, after a constitutional reform in 1988. It is one of the three federal regions of Belgium, along with Flanders and Wallonia, and has bilingual status. The yellow iris is the emblem of the region (referring to the presence of these flowers on the city's original site) and a stylised version is featured on its official flag. + +In recent years, Brussels has become an important venue for international events. In 2000, it was named European Capital of Culture alongside eight other European cities. In 2013, the city was the site of the Brussels Agreement. In 2014, it hosted the 40th G7 summit, and in 2017, 2018 and 2021 respectively the 28th, 29th and 31st NATO Summits. + +On 22 March 2016, three coordinated nail bombings were detonated by ISIL in Brussels—two at Brussels Airport in Zaventem and one at Maalbeek/Maelbeek metro station—resulting in 32 victims and three suicide bombers killed, and 330 people were injured. It was the deadliest act of terrorism in Belgium. + +Geography + +Location and topography + +Brussels lies in the north-central part of Belgium, about from the Belgian coast and about from Belgium's southern tip. It is located in the heartland of the Brabantian Plateau, about south of Antwerp (Flanders), and north of Charleroi (Wallonia). Its average elevation is above sea level, varying from a low point in the valley of the almost completely covered Senne, which cuts the Brussels-Capital Region from east to west, up to high points in the Sonian Forest, on its southeastern side. In addition to the Senne, tributary streams such as the Maalbeek and the Woluwe, to the east of the region, account for significant elevation differences. Brussels' central boulevards are above sea level. Contrary to popular belief, the highest point (at ) is not near the / in Forest, but at the / in the Sonian Forest. + +Climate +Brussels experiences an oceanic climate (Köppen: Cfb) with warm summers and cool winters. Proximity to coastal areas influences the area's climate by sending marine air masses from the Atlantic Ocean. Nearby wetlands also ensure a maritime temperate climate. On average (based on measurements in the period 1981–2010), there are approximately 135 days of rain per year in the Brussels-Capital Region. Snowfall is infrequent, averaging 24 days per year. The city also often experiences violent thunderstorms in summer months. + +Brussels as a capital +Despite its name, the Brussels-Capital Region is not the capital of Belgium. Article 194 of the Belgian Constitution establishes that the capital of Belgium is the City of Brussels, the municipality in the region that is the city's core. + +The City of Brussels is the location of many national institutions. The Royal Palace of Brussels, where the King of the Belgians exercises his prerogatives as head of state, is situated alongside Brussels Park (not to be confused with the Royal Palace of Laeken, the official home of the Belgian Royal Family). The Palace of the Nation is located on the opposite side of this park, and is the seat of the Belgian Federal Parliament. The office of the Prime Minister of Belgium, colloquially called Law Street 16 (, ), is located adjacent to this building. It is also where the Council of Ministers holds its meetings. The Court of Cassation, Belgium's main court, has its seat in the Palace of Justice. Other important institutions in the City of Brussels are the Constitutional Court, the Council of State, the Court of Audit, the Royal Belgian Mint and the National Bank of Belgium. + +The City of Brussels is also the capital of both the French Community of Belgium and the Flemish Community. The Flemish Parliament and Flemish Government have their seats in Brussels, and so do the Parliament of the French Community and the Government of the French Community. + +Municipalities + +The 19 municipalities (, ) of the Brussels-Capital Region are political subdivisions with individual responsibilities for the handling of local level duties, such as law enforcement and the upkeep of schools and roads within its borders. Municipal administration is also conducted by a mayor, a council, and an executive. + +In 1831, Belgium was divided into 2,739 municipalities, including the 19 in the Brussels-Capital Region. Unlike most of the municipalities in Belgium, the ones located in the Brussels-Capital Region were not merged with others during mergers occurring in 1964, 1970, and 1975. However, several municipalities outside the Brussels-Capital Region have been merged with the City of Brussels throughout its history, including Laeken, Haren and Neder-Over-Heembeek in 1921. + +The largest municipality in area and population is the City of Brussels, covering and with 145,917 inhabitants; the least populous is Koekelberg with 18,541 inhabitants. The smallest in area is Saint-Josse-ten-Noode, which is only , but still has the highest population density in the region, with . Watermael-Boitsfort has the lowest population density in the region, with . + +There is much controversy on the division of 19 municipalities for a highly urbanised region, which is considered as (half of) one city by most people. Some politicians mock the "19 baronies" and want to merge the municipalities under one city council and one mayor. That would lower the number of politicians needed to govern Brussels, and centralise the power over the city to make decisions easier, thus reduce the overall running costs. The current municipalities could be transformed into districts with limited responsibilities, similar to the current structure of Antwerp or to structures of other capitals like the boroughs in London or arrondissements in Paris, to keep politics close enough to the citizen. + +In early 2016, Molenbeek-Saint-Jean held a reputation as a safe haven for jihadists in relation to the support shown by some residents towards the bombers who carried out the Paris and Brussels attacks. + +Brussels-Capital Region + +Political status +The Brussels-Capital Region is one of the three federated regions of Belgium, alongside the Walloon Region and the Flemish Region. Geographically and linguistically, it is a bilingual enclave in the monolingual Flemish Region. Regions are one component of Belgium's institutions; the three communities being the other component. Brussels' inhabitants deal with either the French Community or the Flemish Community for matters such as culture and education, as well as a Common Community for competencies which do not belong exclusively to either Community, such as healthcare and social welfare. + +Since the split of Brabant in 1995, the Brussels Region does not belong to any of the provinces of Belgium, nor is it subdivided into provinces itself. Within the Region, 99% of the areas of provincial jurisdiction are assumed by the Brussels regional institutions and community commissions. Remaining is only the governor of Brussels-Capital and some aides, analogously to provinces. Its status is roughly akin to that of a federal district. + +Institutions + +The Brussels-Capital Region is governed by a parliament of 89 members (72 French-speaking, 17 Dutch-speaking—parties are organised on a linguistic basis) and an eight-member regional cabinet consisting of a minister-president, four ministers and three state secretaries. By law, the cabinet must comprise two French-speaking and two Dutch-speaking ministers, one Dutch-speaking secretary of state and two French-speaking secretaries of state. The minister-president does not count against the language quota, but in practice every minister-president has been a bilingual francophone. The regional parliament can enact ordinances (, ), which have equal status as a national legislative act. + +Nineteen of the 72 French-speaking members of the Brussels Parliament are also members of the Parliament of the French Community of Belgium, and, until 2004, this was also the case for six Dutch-speaking members, who were at the same time members of the Flemish Parliament. Now, people voting for a Flemish party have to vote separately for 6 directly elected members of the Flemish Parliament. + +Agglomeration of Brussels +Before the creation of the Brussels-Capital Region, regional competences in the 19 municipalities were performed by the Brussels Agglomeration. The Brussels Agglomeration was an administrative division established in 1971. This decentralised administrative public body also assumed jurisdiction over areas which, elsewhere in Belgium, were exercised by municipalities or provinces. + +The Brussels Agglomeration had a separate legislative council, but the by-laws enacted by it did not have the status of a legislative act. The only election of the council took place on 21 November 1971. The working of the council was subject to many difficulties caused by the linguistic and socio-economic tensions between the two communities. + +After the creation of the Brussels-Capital Region, the Brussels Agglomeration was never formally abolished, although it no longer has a purpose. + +French and Flemish communities + +The French Community and the Flemish Community exercise their powers in Brussels through two community-specific public authorities: the French Community Commission ( or COCOF) and the Flemish Community Commission ( or VGC). These two bodies each have an assembly composed of the members of each linguistic group of the Parliament of the Brussels-Capital Region. They also have a board composed of the ministers and secretaries of state of each linguistic group in the Government of the Brussels-Capital Region. + +The French Community Commission has also another capacity: some legislative powers of the French Community have been devolved to the Walloon Region (for the French language area of Belgium) and to the French Community Commission (for the bilingual language area). The Flemish Community, however, did the opposite; it merged the Flemish Region into the Flemish Community. This is related to different conceptions in the two communities, one focusing more on the Communities and the other more on the Regions, causing an asymmetrical federalism. Because of this devolution, the French Community Commission can enact decrees, which are legislative acts. + +Common Community Commission +A bi-communitarian public authority, the Common Community Commission (, COCOM, , GGC) also exists. Its assembly is composed of the members of the regional parliament, and its board are the ministers—not the secretaries of state—of the region, with the minister-president not having the right to vote. This commission has two capacities: it is a decentralised administrative public body, responsible for implementing cultural policies of common interest. It can give subsidies and enact by-laws. In another capacity, it can also enact ordinances, which have equal status as a national legislative act, in the field of the welfare powers of the communities: in the Brussels-Capital Region, both the French Community and the Flemish Community can exercise powers in the field of welfare, but only in regard to institutions that are unilingual (for example, a private French-speaking retirement home or the Dutch-speaking hospital of the Vrije Universiteit Brussel). The Common Community Commission is responsible for policies aiming directly at private persons or at bilingual institutions (for example, the centres for social welfare of the 19 municipalities). Its ordinances have to be enacted with a majority in both linguistic groups. Failing such a majority, a new vote can be held, where a majority of at least one third in each linguistic group is sufficient. + +Brussels and the European Union + +Brussels serves as de facto capital of the European Union (EU), hosting the major political institutions of the Union. The EU has not declared a capital formally, though the Treaty of Amsterdam formally gives Brussels the seat of the European Commission (the executive branch of government) and the Council of the European Union (a legislative institution made up from executives of member states). It locates the formal seat of European Parliament in Strasbourg, where votes take place, with the council, on the proposals made by the commission. However, meetings of political groups and committee groups are formally given to Brussels, along with a set number of plenary sessions. Three quarters of Parliament sessions now take place at its Brussels hemicycle. Between 2002 and 2004, the European Council also fixed its seat in the city. In 2014, the Union hosted a G7 summit in the city. + +Brussels, along with Luxembourg and Strasbourg, began to host European institutions in 1957, soon becoming the centre of activities, as the Commission and Council based their activities in what has become the European Quarter, in the east of the city. Early building in Brussels was sporadic and uncontrolled, with little planning. The current major buildings are the Berlaymont building of the commission, symbolic of the quarter as a whole, the Europa building of the Council and the Espace Léopold of the Parliament. Today, the presence has increased considerably, with the Commission alone occupying within the European Quarter (a quarter of the total office space in Brussels). The concentration and density has caused concern that the presence of the institutions has created a ghetto effect in that part of the city. However, the European presence has contributed significantly to the importance of Brussels as an international centre. + +International institutions +Brussels has, since World War II, become the administrative centre of many international organisations. The city is the political and administrative centre of the North Atlantic Treaty Organisation (NATO). NATO's Brussels headquarters houses 29 embassies and brings together over 4,500 staff from allied nations, their militaries, and civil service personnel. Many other international organisations such as the World Customs Organization and Eurocontrol, as well as international corporations, have their main institutions in the city. In addition, the main international trade union confederations have their headquarters there: the European Trade Union Confederation (ETUC), the International Confederation of Free Trade Unions (ICFTU) and the World Confederation of Labour (WCL). + +Brussels is third in the number of international conferences it hosts, also becoming one of the largest convention centres in the world. The presence of the EU and the other international bodies has, for example, led to there being more ambassadors and journalists in Brussels than in Washington, D.C. The city hosts 120 international institutions, 181 embassies () and more than 2,500 diplomats, making it the second centre of diplomatic relations in the world (after New York City). International schools have also been established to serve this presence. The "international community" in Brussels numbers at least 70,000 people. In 2009, there were an estimated 286 lobbying consultancies known to work in Brussels. Finally, Brussels has more than 1,400 NGOs. + +North Atlantic Treaty Organisation + +The Treaty of Brussels, which was signed on 17 March 1948 between Belgium, France, Luxembourg, the Netherlands and the United Kingdom, was a prelude to the establishment of the intergovernmental military alliance which later became the North Atlantic Treaty Organization (NATO). Today, the alliance consists of 29 independent member countries across North America and Europe. Several countries also have diplomatic missions to NATO through embassies in Belgium. Since 1949, a number of NATO Summits have been held in Brussels, the most recent taking place in June 2021. The organisation's political and administrative headquarters are located on the / in Haren, on the north-eastern perimeter of the City of Brussels. A new €750 million headquarters building begun in 2010 and was completed in 2017. + +Eurocontrol + +The European Organisation for the Safety of Air Navigation, commonly known as Eurocontrol, is an international organisation which coordinates and plans air traffic control across European airspace. The corporation was founded in 1960 and has 41 member states. Its headquarters are located in Haren, Brussels. + +Demographics + +Population + +Brussels is located in one of the most urbanised regions of Europe, between Paris, London, the Rhine-Ruhr (Germany), and the Randstad (Netherlands). The Brussels-Capital Region has a population of around 1.2 million and has witnessed, in recent years, a remarkable increase in its population. In general, the population of Brussels is younger than the national average, and the gap between rich and poor is wider. + +Brussels is the core of a built-up area that extends well beyond the region's limits. Sometimes referred to as the urban area of Brussels (, ) or Greater Brussels (, ), this area extends over a large part of the two Brabant provinces, including much of the surrounding arrondissement of Halle-Vilvoorde and some small parts of the arrondissement of Leuven in Flemish Brabant, as well as the northern part of Walloon Brabant. + +The metropolitan area of Brussels is divided into three levels. Firstly, the central agglomeration (within the regional borders), with a population of 1,218,255 inhabitants. Adding the closest suburbs (, ) gives a total population of 1,831,496. Including the outer commuter zone (Brussels Regional Express Network (RER/GEN) area), the population is 2,676,701. Brussels is also part of a wider diamond-shaped conurbation, with Ghent, Antwerp and Leuven, which has about 4.4 million inhabitants (a little more than 40% of the Belgium's total population). + +Nationalities + +There have been numerous migrations towards Brussels since the end of the 18th century, when the city acted as a common destination for political refugees from neighbouring or more distant countries, particularly France. From 1871, many of the Paris Communards fled to Brussels, where they received political asylum. Other notable international exiles living in Brussels at the time included Victor Hugo, Karl Marx, Pierre-Joseph Proudhon, Georges Boulanger, and Léon Daudet, to name a few. Attracted by the industrial opportunities, many workers moved in, first from the other Belgian provinces (mainly rural residents from Flanders) and France, then from Southern European, and more recently from Eastern European and African countries. + +Nowadays, Brussels is home to a large number of immigrants and émigré communities, as well as labour migrants, former foreign students or expatriates, and many Belgian families in Brussels can claim at least one foreign grandparent. At the last Belgian census in 1991, 63.7% of inhabitants in Brussels-Capital Region answered that they were Belgian citizens, born as such in Belgium, indicating that more than a third of residents had not been born in the country. According to Statbel (the Belgian Statistical Office), in 2020, taking into account the nationality of birth of the parents, 74.3% of the population of the Brussels-Capital Region was of foreign origin and 41.8% was of non-European origin (including 28.7% of African origin). Among those aged under 18, 88% were of foreign origin and 57% of non-European origin (including 42.4% of African origin). + +This large concentration of immigrants and their descendants includes many of Moroccan (mainly Riffian and other Berbers) and Turkish ancestry, together with French-speaking black Africans from former Belgian colonies, such as the Democratic Republic of the Congo, Rwanda and Burundi. Many immigrants were naturalised following the great 1991 reform of the naturalisation process. In 2012, about 32% of city residents were of non-Belgian European origin (mainly expatriates from France, Romania, Italy, Spain, Poland, and Portugal) and 36% were of another background, mostly from Morocco, Turkey and Sub-Saharan Africa. Among all major migrant groups from outside the EU, a majority of the permanent residents have acquired Belgian nationality. + +Languages + +Brussels was historically Dutch-speaking, using the Brabantian dialect, but over the two past centuries French has become the predominant language of the city. The main cause of this transition was the rapid assimilation of the local Flemish population, amplified by immigration from France and Wallonia. The rise of French in public life gradually began by the end of the 18th century, quickly accelerating after Belgian independence. Dutch — of which standardisation in Belgium was still very weak — could not compete with French, which was the exclusive language of the judiciary, the administration, the army, education, cultural life and the media, and thus necessary for social mobility. The value and prestige of the French language was universally acknowledged to such an extent that after 1880, and more particularly after the turn of the 20th century, proficiency in French among Dutch-speakers in Brussels increased spectacularly. + +Although a majority of the population remained bilingual until the second half of the 20th century, family transmission of the historic Brabantian dialect declined, leading to an increase of monolingual French-speakers from 1910 onwards. From the mid-20th century, the number of monolingual French-speakers surpassed the number of mostly bilingual Flemish inhabitants. This process of assimilation weakened after the 1960s, as the language border was fixed, the status of Dutch as an official language of Belgium was reinforced, and the economic centre of gravity shifted northward to Flanders. However, with the continuing arrival of immigrants and the post-war emergence of Brussels as a centre of international politics, the relative position of Dutch continued to decline. Furthermore, as Brussels' urban area expanded, a further number of Dutch-speaking municipalities in the Brussels periphery also became predominantly French-speaking. This phenomenon of expanding Francisation — dubbed "oil slick" by its opponents — is, together with the future of Brussels, one of the most controversial topics in Belgian politics. + +Today, the Brussels-Capital Region is legally bilingual, with both French and Dutch having official status, as is the administration of the 19 municipalities. The creation of this bilingual, full-fledged region, with its own competencies and jurisdiction, had long been hampered by different visions of Belgian federalism. Nevertheless, some communitarian issues remain. Flemish political parties demanded, for decades, that the Flemish part of Brussels-Halle-Vilvoorde (BHV) arrondissement be separated from the Brussels Region (which made Halle-Vilvoorde a monolingual Flemish electoral and judicial district). BHV was divided mid-2012. The French-speaking population regards the language border as artificial and demands the extension of the bilingual region to at least all six municipalities with language facilities in the surroundings of Brussels. Flemish politicians have strongly rejected these proposals. + +Owing to migration and to its international role, Brussels is home to a large number of native speakers of languages other than French or Dutch. Currently, about half of the population speaks a home language other than these two. In 2013, academic research showed that approximately 17% of families spoke none of the official languages in the home, while in a further 23% a foreign language was used alongside French. The share of unilingual French-speaking families had fallen to 38% and that of Dutch-speaking families to 5%, while the percentage of bilingual Dutch-French families reached 17%. At the same time, French remains widely spoken: in 2013, French was spoken "well to perfectly" by 88% of the population, while for Dutch this percentage was only 23% (down from 33% in 2000); the other most commonly known languages were English (30%), Arabic (18%), Spanish (9%), German (7%) and Italian and Turkish (5% each). Despite the rise of English as a second language in Brussels, including as an unofficial compromise language between French and Dutch, as well as the working language for some of its international businesses and institutions, French remains the lingua franca and all public services are conducted exclusively in French or Dutch. + +The original dialect of Brussels (known as Brusselian, and also sometimes referred to as Marols or Marollien), a form of Brabantic (the variant of Dutch spoken in the ancient Duchy of Brabant) with a significant number of loanwords from French, still survives among a small minority of inhabitants called Brusseleers (or Brusseleirs), many of them quite bi- and multilingual, or educated in French and not writing in Dutch. The ethnic and national self-identification of Brussels' inhabitants is nonetheless sometimes quite distinct from the French and Dutch-speaking communities. For the French-speakers, it can vary from Francophone Belgian, (French demonym for an inhabitant of Brussels), Walloon (for people who migrated from the Walloon Region at an adult age); for Flemings living in Brussels, it is mainly either Dutch-speaking Belgian, Flemish or (Dutch demonym for an inhabitant), and often both. For the Brusseleers, many simply consider themselves as belonging to Brussels. + +Religions + +Historically, Brussels has been predominantly Roman Catholic, especially since the expulsion of Protestants in the 16th century. This is clear from the large number of historical churches in the region, particularly in the City of Brussels. The pre-eminent Catholic cathedral in Brussels is the Cathedral of St. Michael and St. Gudula, serving as the co-cathedral of the Archdiocese of Mechelen–Brussels. On the north-western side of the region, the National Basilica of the Sacred Heart is a Minor Basilica and parish church, as well as one of the largest churches by area in the world. The Church of Our Lady of Laeken holds the tombs of many members of the Belgian Royal Family, including all the former Belgian monarchs, within the Royal Crypt. + +In reflection of its multicultural makeup, Brussels hosts a variety of religious communities, as well as large numbers of atheists and agnostics. Minority faiths include Islam, Anglicanism, Eastern Orthodoxy, Judaism, and Buddhism. According to a 2016 survey, approximately 40% of residents of Brussels declared themselves Catholics (12% were practising Catholics and 28% were non-practising Catholics), 30% were non-religious, 23% were Muslim (19% practising, 4% non-practising), 3% were Protestants and 4% were of another religion. + +As guaranteed by Belgian law, recognised religions and non-religious philosophical organisations (, ) enjoy public funding and school courses. It was once the case that every pupil in an official school from 6 to 18 years old had to choose two hours per week of compulsory religious—or non-religious-inspired morals—courses. However, in 2015, the Belgian Constitutional Court ruled religious studies could no longer be required in the primary and secondary educational systems. + +Brussels has a large concentration of Muslims, mostly of Moroccan, Turkish, Syrian and Guinean ancestry. The Great Mosque of Brussels, located in the Parc du Cinquantenaire/Jubelpark, is the oldest mosque in Brussels. Belgium does not collect statistics by ethnic background or religious beliefs, so exact figures are unknown. It was estimated that, in 2005, people of Muslim background living in the Brussels Region numbered 256,220 and accounted for 25.5% of the city's population, a much higher concentration than those of the other regions of Belgium. + +Culture + +Architecture +The architecture in Brussels is diverse, and spans from the clashing combination of Gothic, Baroque, and Louis XIV styles on the Grand-Place to the postmodern buildings of the EU institutions. + +Very little medieval architecture is preserved in Brussels. Buildings from that period are mostly found in the historical centre (called ), Saint Géry/Sint-Goriks and / neighbourhoods. The Brabantine Gothic Cathedral of St. Michael and St. Gudula remains a prominent feature in the skyline of downtown Brussels. Isolated portions of the first city walls were saved from destruction and can be seen to this day. One of the only remains of the second walls is the Halle Gate. The Grand-Place is the main attraction in the city centre and has been a UNESCO World Heritage Site since 1998. The square is dominated by the 15th century Flamboyant Town Hall, the neo-Gothic Breadhouse and the Baroque guildhalls of the former Guilds of Brussels. Manneken Pis, a fountain containing a small bronze sculpture of a urinating youth, is a tourist attraction and symbol of the city. + +The neoclassical style of the 18th and 19th centuries is represented in the Royal Quarter/Coudenberg area, around Brussels Park and the Place Royale/Koningsplein. Examples include the Royal Palace, the Church of St. James on Coudenberg, the Palace of the Nation (Parliament building), the Academy Palace, the Palace of Charles of Lorraine, the Palace of the Count of Flanders and the Egmont Palace. Other uniform neoclassical ensembles can be found around the Place des Martyrs/Martelaarsplein and the /. Some additional landmarks in the centre are the Royal Saint-Hubert Galleries (1847), one of the oldest covered shopping arcades in Europe, the Congress Column (1859), the former Brussels Stock Exchange building (1873) and the Palace of Justice (1883). The latter, designed by Joseph Poelaert, in eclectic style, is reputed to be the largest building constructed in the 19th century. + +Located outside the historical centre, in a greener environment bordering the European Quarter, are the Parc du Cinquantenaire/Jubelpark with its memorial arcade and nearby museums, and in Laeken, the Royal Palace of Laeken and the Royal Domain with its large greenhouses, as well as the Museums of the Far East. + +Also particularly striking are the buildings in the Art Nouveau style, most famously by the Belgian architects Victor Horta, Paul Hankar and Henry Van de Velde. Some of Brussels' municipalities, such as Schaerbeek, Etterbeek, Ixelles, and Saint-Gilles, were developed during the heyday of Art Nouveau and have many buildings in that style. The Major Town Houses of the Architect Victor Horta—Hôtel Tassel (1893), Hôtel Solvay (1894), Hôtel van Eetvelde (1895) and the Horta Museum (1901)—have been listed as a UNESCO World Heritage Site since 2000. Another example of Brussels' Art Nouveau is the Stoclet Palace (1911), by the Viennese architect Josef Hoffmann, designated a World Heritage Site by UNESCO in June 2009. + +Art Deco structures in Brussels include the Résidence Palace (1927) (now part of the Europa building), the Centre for Fine Arts (1928), the Villa Empain (1934), the Town Hall of Forest (1938), and the Flagey Building (formerly known as the Maison de la Radio) on the Place Eugène Flagey/Eugène Flageyplein (1938) in Ixelles. Some religious buildings from the interwar era were also constructed in that style, such as the Church of St. John the Baptist (1932) in Molenbeek and the Church of St. Augustine (1935) in Forest. Completed only in 1969, and combining Art Deco with neo-Byzantine elements, the Basilica of the Sacred Heart in Koekelberg is one of the largest churches by area in the world, and its cupola provides a panoramic view of Brussels and its outskirts. Another example are the exhibition halls of the Centenary Palace, built for the 1935 World's Fair on the Heysel/Heizel Plateau in northern Brussels, home to the Brussels Exhibition Centre (Brussels Expo). + +The Atomium is a symbolic modernist structure, located on the Heysel Plateau, which was originally built for the 1958 World's Fair (Expo 58). It consists of nine steel spheres connected by tubes, and forms a model of an iron crystal (specifically, a unit cell), magnified 165 billion times. The architect André Waterkeyn devoted the building to science. It is now considered a landmark of Brussels. Next to the Atomium, is Mini-Europe miniature park, with 1:25 scale maquettes of famous buildings from across Europe. + +Since the second half of the 20th century, modern office towers have been built in Brussels (Madou Tower, Rogier Tower, Proximus Towers, Finance Tower, the World Trade Center, among others). There are some thirty towers, mostly concentrated in the city's main business district: the Northern Quarter (also called Little Manhattan), near Brussels-North railway station. The South Tower, standing adjacent to Brussels-South railway station, is the tallest building in Belgium, at . Along the North–South connection, is the State Administrative City, an administrative complex in the International Style. The postmodern buildings of the Espace Léopold complete the picture. + +The city's embrace of modern architecture translated into an ambivalent approach towards historic preservation, leading to the destruction of notable architectural landmarks, most famously the Maison du Peuple/Volkshuis by Victor Horta, a process known as Brusselisation. + +Arts + +Brussels contains over 80 museums. The Royal Museums of Fine Arts has an extensive collection of various painters, such as Flemish old masters like Bruegel, Rogier van der Weyden, Robert Campin, Anthony van Dyck, Jacob Jordaens, and Peter Paul Rubens. The Magritte Museum houses the world's largest collection of the works of the surrealist René Magritte. Museums dedicated to the national history of Belgium include the BELvue Museum, the Royal Museums of Art and History, and the Royal Museum of the Armed Forces and Military History. The Musical Instruments Museum (MIM), housed in the Old England building, is part of the Royal Museums of Art and History, and is internationally renowned for its collection of over 8,000 instruments. + +The Brussels Museums Council is an independent body for all the museums in the Brussels-Capital Region, covering around 100 federal, private, municipal, and community museums. It promotes member museums through the Brussels Card (giving access to public transport and 30 of the 100 museums), the Brussels Museums Nocturnes (every Thursday from 5 p.m. to 10 p.m. from mid-September to mid-December) and the Museum Night Fever (an event for and by young people on a Saturday night in late February or early March). + +Brussels has had a distinguished artist scene for many years. The famous Belgian surrealists René Magritte and Paul Delvaux, for instance, studied and lived there, as did the avant-garde dramatist Michel de Ghelderode. The city was also home of the impressionist painter Anna Boch from the artists' group Les XX, and includes other famous Belgian painters such as Léon Spilliaert. Brussels is also a capital of the comic strip; some treasured Belgian characters are Tintin, Lucky Luke, The Smurfs, Spirou, Gaston, Marsupilami, Blake and Mortimer, Boule et Bill and Cubitus (see Belgian comics). Throughout the city, walls are painted with large motifs of comic book characters; these murals taken together are known as Brussels' Comic Book Route. Also, the interiors of some Metro stations are designed by artists. The Belgian Comic Strip Center combines two artistic leitmotifs of Brussels, being a museum devoted to Belgian comic strips, housed in the former Magasins Waucquez textile department store, designed by Victor Horta in the Art Nouveau style. In addition, street art is changing the landscape of this multicultural city. + +Brussels is well known for its performing arts scene, with the Royal Theatre of La Monnaie, the Royal Park Theatre, the Théâtre Royal des Galeries and the Kaaitheater among the most notable institutions. The Kunstenfestivaldesarts, an international performing arts festival, is organised every year in May in about twenty different cultural houses and theatres throughout the city. The King Baudouin Stadium is a concert and competition facility with a 50,000 seat capacity, the largest in Belgium. The site was formerly occupied by the Heysel Stadium. The Center for Fine Arts (often referred to as BOZAR in French or PSK in Dutch), a multi-purpose centre for theatre, cinema, music, literature and art exhibitions, is home to the National Orchestra of Belgium and to the annual Queen Elisabeth Competition for classical singers and instrumentalists, one of the most challenging and prestigious competitions of the kind. Studio 4 in Le Flagey cultural centre hosts the Brussels Philharmonic. Other concert venues include Forest National/Vorst Nationaal, the Ancienne Belgique, the Cirque Royal/Koninklijk Circus, the Botanique and Palais 12/Paleis 12. Furthermore, the Jazz Station in Saint-Josse-ten-Noode is a museum and archive on jazz, and a venue for jazz concerts. + +Folklore + +Brussels' identity owes much to its rich folklore and traditions, among the liveliest in the country. + The Ommegang, a folkloric costumed procession, commemorating the Joyous Entry of Emperor Charles V and his son Philip II in the city in 1549, takes place every year in July. The colourful parade includes floats, traditional processional giants, such as Saint Michael and Saint Gudula, and scores of folkloric groups, either on foot or on horseback, dressed in medieval garb. The parade ends in a pageant on the Grand-Place. Since 2019, it is recognised as a Masterpiece of the Oral and Intangible Heritage of Humanity by UNESCO. + The Meyboom, an even-older folk tradition of Brussels (1308), celebrating the "May tree"—in fact, a corruption of the Dutch tree of joy—takes place paradoxically on 9 August. After parading a young beech in the city, it is planted in a joyful spirit with lots of music, Brusseleir songs, and processional giants. It was also recognised as an expression of intangible cultural heritage by UNESCO, as part of the bi-national inscription "Processional giants and dragons in Belgium and France". The celebration is reminiscent of the town's long-standing (folkloric) feud with Leuven, which dates back to the Middle Ages. + Another good introduction to the Brusseleir local dialect and way of life can be obtained at the Royal Theatre Toone, a folkloric theatre of marionettes, located a stone's throw away from the Grand-Place. + The Saint-Verhaegen (often shortened to St V), a folkloric student procession, celebrating the anniversary of the founding of the (ULB) and the (VUB), is held on 20 November. + +Cultural events and festivals + +Many events are organised or hosted in Brussels throughout the year. In addition, many festivals animate the Brussels scene. + +The Iris Festival is the official festival of the Brussels-Capital Region and is held annually in spring. The International Fantastic Film Festival of Brussels (BIFFF) is organised during the Easter holidays and the Magritte Awards in February. The Festival of Europe, an open day and activities in and around the institutions of the European Union, is held on 9 May. On Belgian National Day, on 21 July, a military parade and celebrations take place on the / and in Brussels Park, ending with a display of fireworks in the evening. + +Some summer festivities include Couleur Café Festival, a festival of world and urban music, around the end of June or early July, the Brussels Summer Festival (BSF), a music festival in August, the Brussels Fair, the most important yearly fair in Brussels, lasting more than a month, in July and August, and Brussels Beach, when the banks of the canal are turned into a temporary urban beach. Other biennial events are the Zinneke Parade, a colourful, multicultural parade through the city, which has been held since 2000 in May, as well as the popular Flower Carpet at the Grand-Place in August. Heritage Days are organised on the third weekend of September (sometimes coinciding with the car-free day) and are a good opportunity to discover the wealth of buildings, institutions and real estate in Brussels. The "Winter Wonders" animate the heart of Brussels in December; these winter activities were launched in Brussels in 2001. + +Cuisine + +Brussels is well known for its local waffle, its chocolate, its French fries and its numerous types of beers. The Brussels sprout, which has long been popular in Brussels, and may have originated there, is also named after the city. + +The gastronomic offer includes approximately 1,800 restaurants (including three 2-starred and ten 1-starred Michelin restaurants), and a number of bars. In addition to the traditional restaurants, there are many cafés, bistros and the usual range of international fast food chains. The cafés are similar to bars, and offer beer and light dishes; coffee houses are called (literally "tea salons"). Also widespread are brasseries, which usually offer a variety of beers and typical national dishes. + +Belgian cuisine is known among connoisseurs as one of the best in Europe. It is characterised by the combination of French cuisine with the more hearty Flemish fare. Notable specialities include Brussels waffles (gaufres) and mussels (usually as moules-frites, served with fries). The city is a stronghold of chocolate and praline manufacturers with renowned companies like Côte d'Or, Neuhaus, Leonidas and Godiva. Pralines were first introduced in 1912 by Jean Neuhaus II, a Belgian chocolatier of Swiss origin, in the Royal Saint-Hubert Galleries. Numerous friteries are spread throughout the city, and in tourist areas, fresh hot waffles are also sold on the street. + +As well as other Belgian beers, the spontaneously fermented lambic style, brewed in and around Brussels, is widely available there and in the nearby Senne valley where the wild yeasts that ferment it have their origin. Kriek, a cherry lambic, is available in almost every bar or restaurant in Brussels. + +Brussels is known as the birthplace of the Belgian endive. The technique for growing blanched endives was accidentally discovered in the 1850s at the Botanical Garden of Brussels in Saint-Josse-ten-Noode. + +Shopping + +Famous shopping areas in Brussels include the pedestrian-only Rue Neuve/Nieuwstraat, the second busiest shopping street in Belgium (after the Meir, in Antwerp) with a weekly average of 230,000 visitors, home to popular international chains (H&M, C&A, Zara, Primark), as well as the City 2 and Anspach galleries. The Royal Saint-Hubert Galleries hold a variety of luxury shops and some six million people stroll through them each year. The neighbourhood around the / has become, in recent years, a focal point for fashion and design; this main street and its side streets also feature Belgium's young and most happening artistic talent. + +In Ixelles, the / and the Namur Gate area offer a blend of luxury shops, fast food restaurants and entertainment venues, and the /, in the mainly-Congolese Matongé district, offers a great taste of African fashion and lifestyle. The nearby Avenue Louise/Louizalaan is lined with high-end fashion stores and boutiques, making it one of the most expensive streets in Belgium. + +There are shopping centres outside the inner ring: Basilix, Woluwe Shopping Center, Westland Shopping Center, and Docks Bruxsel, which opened in October 2017. In addition, Brussels ranks as one of Europe's best capital cities for flea market shopping. The Old Market, on the Place du Jeu de Balle/Vossenplein, in the Marolles/Marollen neighbourhood, is particularly renowned. The nearby Sablon/Zavel area is home to many of Brussels' antique dealers. The Midi Market around Brussels-South station and the / is reputed to be one of the largest markets in Europe. + +Sports + +Sport in Brussels is under the responsibility of the Communities. The (ADEPS) is responsible for recognising the various French-speaking sports federations and also runs three sports centres in the Brussels-Capital Region. Its Dutch-speaking counterpart is (formerly called BLOSO). + +The King Baudouin Stadium (formerly the Heysel Stadium) is the largest in the country and home to the national teams in football and rugby union. It hosted the final of the 1972 UEFA European Football Championship, and the opening game of the 2000 edition. Several European club finals have been held at the ground, including the 1985 European Cup Final which saw 39 deaths due to hooliganism and structural collapse. The King Baudouin Stadium is also home of the annual Memorial Van Damme athletics event, Belgium's foremost track and field competition, which is part of the Diamond League. Other important athletics events are the Brussels Marathon and the 20 km of Brussels, an annual run with 30,000 participants. + +Cycling +Brussels is home to notable cycling races. The city is the arrival location of the Brussels Cycling Classic, formerly known as Paris–Brussels, which is one of the oldest semi classic bicycle races on the international calendar. From World War I until the early 1970s, the Six Days of Brussels was organised regularly. In the last decades of the 20th century, the Grand Prix Eddy Merckx was also held in Brussels. + +Association football + +R.S.C. Anderlecht, based in the Constant Vanden Stock Stadium in Anderlecht, is the most successful Belgian football club in the Belgian Pro League, with 34 titles. It has also won the most major European tournaments for a Belgian side, with 6 European titles. Brussels is also home to Union Saint-Gilloise, the most successful Belgian club before World War II, with 11 titles. The club was founded in Saint-Gilles but is based in nearby Forest, and plays in the Belgian Pro League. Racing White Daring Molenbeek, based in Molenbeek-Saint-Jean, and often referred to as RWDM, is a very popular football club that, since 2023, is back playing in the Belgian Pro League. + +Other Brussels clubs that played in the national series over the years were Royal White Star Bruxelles, Ixelles SC, Crossing Club de Schaerbeek (born from a merger between RCS de Schaerbeek and Crossing Club Molenbeek), Scup Jette, RUS de Laeken, Racing Jet de Bruxelles, AS Auderghem, KV Wosjot Woluwe and FC Ganshoren. + +Economy + +Serving as the centre of administration for Belgium and Europe, Brussels' economy is largely service-oriented. It is dominated by regional and world headquarters of multinationals, by European institutions, by various local and federal administrations, and by related services companies, though it does have a number of notable craft industries, such as the Cantillon Brewery, a lambic brewery founded in 1900. + +Brussels has a robust economy. The region contributes to one fifth of Belgium's GDP, and its 550,000 jobs account for 17.7% of Belgium's employment. Its GDP per capita is nearly double that of Belgium as a whole, and it has the highest GDP per capita of any NUTS 1 region in the EU, at ~$80,000 in 2016. That being said, the GDP is boosted by a massive inflow of commuters from neighbouring regions; over half of those who work in Brussels live in Flanders or Wallonia, with 230,000 and 130,000 commuters per day respectively. Conversely, only 16.0% of people from Brussels work outside Brussels (68,827 (68.5%) of them in Flanders and 21,035 (31.5%) in Wallonia). Not all of the wealth generated in Brussels remains in Brussels itself, and , the unemployment among residents of Brussels is 20.4%. + +There are approximately 50,000 businesses in Brussels, of which around 2,200 are foreign. This number is constantly increasing and can well explain the role of Brussels in Europe. The city's infrastructure is very favourable in terms of starting up a new business. House prices have also increased in recent years, especially with the increase of young professionals settling down in Brussels, making it the most expensive city to live in Belgium. In addition, Brussels holds more than 1,000 business conferences annually, making it the ninth most popular conference city in Europe. + +Brussels is rated as the 34th most important financial centre in the world as of 2020, according to the Global Financial Centres Index. The Brussels Stock Exchange, abbreviated to BSE, now called Euronext Brussels, is part of the European stock exchange Euronext, along with Paris Bourse, Lisbon Stock Exchange and Amsterdam Stock Exchange. Its benchmark stock market index is the BEL20. + +Media + +Brussels is a centre of both media and communications in Belgium, with many Belgian television stations, radio stations, newspapers and telephone companies having their headquarters in the region. The French-language public broadcaster RTBF, the Dutch-language public broadcaster VRT, the two regional channels BX1 (formerly Télé Bruxelles) and Bruzz (formerly TV Brussel), the encrypted BeTV channel and private channels RTL-TVI and VTM are headquartered in Brussels. Some national newspapers such as Le Soir, La Libre, De Morgen and the news agency Belga are based in or around Brussels. The Belgian postal company bpost, as well as the telecommunication companies and mobile operators Proximus, Orange Belgium and Telenet are all located there. + +As English is spoken widely, several English media organisations operate in Brussels. The most popular of these are the English-language daily news media platform and bi-monthly magazine The Brussels Times and the quarterly magazine and website The Bulletin. The multilingual pan-European news channel Euronews also maintains an office in Brussels. + +Education + +Tertiary education + +There are several universities in Brussels. Except for the Royal Military Academy, a federal military college established in 1834, all universities in Brussels are private and autonomous. The Royal Military Academy also the only Belgian university organised on the boarding school model. + +The Université libre de Bruxelles (ULB), a French-speaking university, with about 20,000 students, has three campuses in the city, and the Vrije Universiteit Brussel (VUB), its Dutch-speaking sister university, has about 10,000 students. Both universities originate from a single ancestor university, founded in 1834, namely the Free University of Brussels, which was split in 1970, at about the same time the Flemish and French Communities gained legislative power over the organisation of higher education. + +Saint-Louis University, Brussels (also known as UCLouvain Saint-Louis – Bruxelles) was founded in 1858 and is specialised in social and human sciences, with 4,000 students, and located on two campuses in the City of Brussels and Ixelles. From September 2018 on, the university uses the name UCLouvain, together with the Catholic University of Louvain, in the context of a merger between both universities. + +Still other universities have campuses in Brussels, such as the French-speaking Catholic University of Louvain (UCLouvain), which has 10,000 students in the city with its medical faculties at UCLouvain Bruxelles Woluwe since 1973, in addition to its Faculty of Architecture, Architectural Engineering and Urban Planning and UCLouvain's Dutch-speaking sister Katholieke Universiteit Leuven (KU Leuven) (offering bachelor's and master's degrees in economics & business, law, arts, and architecture; 4,400 students). In addition, the University of Kent's Brussels School of International Studies is a specialised postgraduate school offering advanced international studies. + +Also a dozen of university colleges are located in Brussels, including two drama schools, founded in 1832: the French-speaking Conservatoire Royal and its Dutch-speaking equivalent, the Koninklijk Conservatorium. + +Primary and secondary education +Most of Brussels pupils between the ages of 3 and 18 go to schools organised by the French-speaking Community or the Flemish Community, with close to 80% going to French-speaking schools, and roughly 20% to Dutch-speaking schools. Due to the post-war international presence in the city, there are also a number of international schools, including the International School of Brussels, with 1,450 pupils, between the ages of and 18, the British School of Brussels, and the four European Schools, which provide free education for the children of those working in the EU institutions. The combined student population of the four European Schools in Brussels is around 10,000. + +Libraries + +Brussels has a number of public or private-owned libraries on its territory. Most public libraries in Brussels fall under the competence of the Communities and are usually separated between French-speaking and Dutch-speaking institutions, although some are mixed. + +The Royal Library of Belgium (KBR) is the national library of Belgium and one of the most prestigious libraries in the world. It owns several collections of historical importance, like the famous Fétis archives, and is the depository for all books ever published in Belgium or abroad by Belgian authors. It is located on the Mont des Arts/Kunstberg in central Brussels, near the Central Station. + +There are several academic libraries and archives in Brussels. The libraries of the Université libre de Bruxelles (ULB) and the Vrije Universiteit Brussel (VUB) constitute the largest ensemble of university libraries in the city. In addition to the Solbosch location, there are branches in La Plaine and Erasme/Erasmus. Other academic libraries include those of Saint-Louis University, Brussels and the Catholic University of Louvain (UCLouvain). + +Science and technology + +Science and technology in Brussels is well developed with the presence of several universities and research institutes. The Brussels-Capital Region is home to several national science and technology institutes including the National Fund for Scientific Research (NFSR), the Institute for the Encouragement of Scientific Research and Innovation of Brussels (ISRIB), the Royal Academies for Science and the Arts of Belgium (RASAB) and the Belgian Academy Council of Applied Sciences (BACAS). Several science parks associated with the universities are also spread over the region. + +The Royal Belgian Institute of Natural Sciences, located in Leopold Park, houses the world's largest hall completely dedicated to dinosaurs, with its collection of 30 fossilised Iguanodon skeletons. In addition, the Planetarium of the Royal Observatory of Belgium (part of the institutions of the Belgian Federal Science Policy Office), on the Heysel Plateau in Laeken, is one of the largest in Europe. + +Healthcare + +Brussels is home to a thriving pharmaceutical and health care industry which includes pioneering biotechnology research. The health sector employs 70,000 employees in 30,000 companies. There are 3,000 life sciences researchers in the city and two large science parks: Da Vinci Research Park and Erasmus Research Park. There are five university hospitals, a military hospital and more than 40 general hospitals and specialist clinics. + +Due to its bilingual nature, hospitals in the Brussels-Capital Region can be either monolingual French, monolingual Dutch, or bilingual, depending on their nature. University hospitals belong to one of the two linguistic communities and are thus monolingual French or Dutch by law. Other hospitals managed by a public authority must be legally bilingual. Private hospitals are legally not bound to either language, but most cater to both. However, all hospital emergency services in the Capital Region (whether part of a public or private hospital) are required to be bilingual, since patients transported by emergency ambulance cannot choose the hospital they will be brought to. + +Transport + +Brussels has an extensive network of both private or public transportation means. Public transportation includes Brussels buses, trams, and metro (all three operated by the Brussels Intercommunal Transport Company (STIB/MIVB)), as well as a set of railway lines (operated by Infrabel) and railway stations served by public trains (operated by the National Railway Company of Belgium (NMBS/SNCB)). Air transport is available via one of the city's two airports (Brussels Airport and Brussels South Charleroi Airport), and boat transport is available via the Port of Brussels. Bicycle-sharing and car-sharing public systems are also available. + +The complexity of the Belgian political landscape makes some transportation issues difficult to solve. The Brussels-Capital Region is surrounded by the Flemish and Walloon regions, which means that the airports, as well as many roads serving Brussels (most notably the Brussels Ring) are located in the other two Belgian regions. The city is relatively car-dependent by northern European standards and is considered to be the most congested city in the world according to the INRIX traffic survey. + +Air + +The Brussels-Capital Region is served by two airports, both located outside of the administrative territory of the region. The most notable is Brussels Airport, located in the nearby Flemish municipality of Zaventem, east of the capital, which can be accessed by highway (A201), train and bus. The secondary airport is Brussels South Charleroi Airport, located in Gosselies, a part of the city of Charleroi (Wallonia), some south-west of Brussels, which can be accessed by highway (E19 then E420) or a private bus. There is also Melsbroek Air Base, located in Steenokkerzeel, a military airport which shares its infrastructure with Brussels Airport. The aforementioned airports are also the main airports of Belgium. + +Water + +Since the 16th century, Brussels has had its own harbour, the Port of Brussels. It has been enlarged throughout the centuries to become the second Belgian inland port. Historically situated near the /, it lies today to the north-west of the region, on the Brussels–Scheldt Maritime Canal (commonly called Willebroek Canal), which connects Brussels to Antwerp via the Scheldt. Ships and large barges up to can penetrate deep into the country, avoiding break-ups and load transfers between Antwerp and the centre of Brussels, hence reducing the cost for companies using the canal, and thus offering a competitive advantage. + +Moreover, the connection of the Willebroek Canal with the Brussels–Charleroi Canal, in the very heart of the capital, creates a north–south link, by means of waterways, between the Netherlands, Flanders and the industrial zone of Hainaut (Wallonia). There, navigation can access the network of French canals, thanks to the important inclined plane of Ronquières and the lifts of Strépy-Bracquegnies. + +The importance of river traffic in Brussels makes it possible to avoid the road equivalent of 740,000 trucks per year—almost 2,000 per day—which, in addition to easing traffic problems, represents an estimated carbon dioxide saving of per year. + +Train + +The Brussels-Capital Region has three main train stations: Brussels-South, Brussels-Central and Brussels-North, which are also the busiest of the country. Brussels-South is also served by direct high-speed rail links: to London by Eurostar trains via the Channel Tunnel (1hr 51min); to Amsterdam by Thalys and InterCity connections; to Amsterdam, Paris (1hr 50min and 1hr 25min respectively ), and Cologne by Thalys; and to Cologne (1hr 50min) and Frankfurt (2hr 57min) by the German ICE. + +The train rails in Brussels go underground, near the centre, through the North–South connection, with Brussels Central Station also being largely underground. The tunnel itself is only six tracks wide at its narrowest point, which often causes congestion and delays due to heavy use of the route. + +The City of Brussels has minor railway stations at Bockstael, Brussels-Chapel, Brussels-Congres, Brussels-Luxembourg, Brussels-Schuman, Brussels-West, Haren, Haren-South and Simonis. In the Brussels Region, there are also railways stations at Berchem-Sainte-Agathe, Boitsfort, Boondael, Bordet (Evere), Etterbeek, Evere, Forest-East, Forest-South, Jette, Meiser (Schaerbeek), Moensberg (Uccle), Saint-Job (Uccle), Schaarbeek, Uccle-Calevoet, Uccle-Stalle, Vivier d'Oie-Diesdelle (Uccle), Merode and Watermael. + +Public transport +The Brussels Intercommunal Transport Company (STIB/MIVB) is the local public transport operator in Brussels. It covers the 19 municipalities of the Brussels-Capital Region and some surface routes extend to the near suburbs in the other two regions, linking with the De Lijn network in Flanders and the TEC network in Wallonia. + +Metro, trams and buses + +The Brussels Metro dates back to 1976, but underground lines known as the premetro have been serviced by tramways since 1968. It is the only rapid transit system in Belgium (Antwerp and Charleroi both having light rail systems). The network consists of four conventional metro lines and three premetro lines. The metro-grade lines are M1, M2, M5, and M6, with some shared sections, covering a total of . , the Metro network within the region has a total of 69 metro and premetro stations. The Metro is an important means of transport, connecting with six railway stations of the National Railway Company of Belgium (NMBS/SNCB), and many tram and bus stops operated by STIB/MIVB, and with Flemish De Lijn and Walloon TEC bus stops. + +A comprehensive bus and tram network covers the region. , the Brussels tram system consists of 17 tram lines (three of which – lines T3, T4 and T7 – qualify as premetro lines that partly travel over underground sections that were intended to be eventually converted into metro lines). The total route length is , making it one of the largest tram networks in Europe. The Brussels bus network is complementary to the rail network. It consists of 50 bus routes and 11 night routes, spanning . + +Since April 2007, STIB/MIVB has also been operating a night bus network called Noctis on Friday and Saturday nights from midnight until 3 a.m. The service consists of 11 routes (N04, N05, N06, N08, N09, N10, N11, N12, N13, N16 and N18). The fare on these night buses is the same as during the day. All the lines leave from the Place de la Bourse/Beursplein in the city centre at 30 minutes intervals and cover all the main streets in the capital, as they radiate outwards to the suburbs. Noctis services returned from 2 July 2021 after over a year of disruption due to the COVID-19 pandemic in Belgium. + +Ticketing +MoBIB is the STIB/MIVB electronic smart card, introduced in 2007, replacing the discontinued paper tickets. The hourly travel fare includes all means of transport (metro, tram and bus) operated by STIB/MIVB. Each trip has a different cost depending on the type of support purchased. Passengers can purchase monthly passes, yearly passes, 1 and 10-trip tickets and daily and 3-day passes. These can be bought over the Internet, but require customers to have a smart card reader. GO vending machines accept coins, local and international chip and PIN credit and debit cards. + +Moreover, a complimentary interticketing system means that a combined STIB/MIVB ticket holder can, depending on the option, also use the train network operated by NMBS/SNCB and/or long-distance buses and commuter services operated by De Lijn or TEC. With this ticket, a single journey can include multiple stages across the different modes of transport and networks. + +Other public transport + +Since 2003, Brussels has had a car-sharing service operated by the Bremen company Cambio, in partnership with STIB/MIVB and the local ridesharing company Taxi Stop. In 2006, a public bicycle-sharing programme was introduced. The scheme was subsequently taken over by Villo!. Since 2008, this night-time public transport service has been supplemented by Collecto, a shared taxi system, which operates on weekdays between 11 p.m. and 6 a.m. In 2012, the Zen Car electric car-sharing scheme was launched in the university and European areas. + +Road network + +In medieval times, Brussels stood at the intersection of routes running north–south (the modern /) and east–west (/–/–/). The ancient pattern of streets, radiating from the Grand-Place, in large part remains, but has been overlaid by boulevards built over the river Senne, over the city walls and over the railway connection between the North and South Stations. Today, Brussels has the most congested traffic in North America and Europe, according to US traffic information platform INRIX. + +Brussels is the hub of a range of national roads, the main ones being clockwise: the N1 (N to Breda), N2 (E to Maastricht), N3 (E to Aachen), N4 (SE to Luxembourg), N5 (S to Rheims), N6 (S to Maubeuge), N7 (SW to Lille), N8 (W to Koksijde) and N9 (NW to Ostend). Usually named /, these highways normally run in a straight line, but sometimes lose themselves in a maze of narrow shopping streets. The region is skirted by the European route E19 (N-S) and the E40 (E-W), while the E411 leads away to the SE. Brussels has an orbital motorway, numbered R0 (R-zero) and commonly referred to as the Ring. It is pear-shaped, as the southern side was never built as originally conceived, owing to residents' objections. + +The city centre, sometimes known as the Pentagon, is surrounded by an inner ring road, the Small Ring (, ), a sequence of boulevards formally numbered R20 or N0. These were built upon the site of the second set of city walls following their demolition. The Metro line 2 runs under much of these. Since June 2015, a number of central boulevards inside the Pentagon have become car-free, limiting transit traffic through the old city. + +On the eastern side of the region, the R21 or Greater Ring (, ) is formed by a string of boulevards that curves round from Laeken to Uccle. Some premetro stations (see Brussels Metro) were built on that route. A little further out, a stretch numbered R22 leads from Zaventem to Saint-Job. + +Security and emergency services + +Police + +The Brussels local police, supported by the federal police, is responsible for law enforcement in Brussels. The 19 municipalities of the Brussels-Capital Region are divided into six police zones, all bilingual (French and Dutch): +5339 Brussels Capital Ixelles: the City of Brussels and Ixelles +5340 Brussels West: Berchem-Sainte-Agathe, Ganshoren, Jette, Koekelberg and Molenbeek-Saint-Jean +5341 South: Anderlecht, Forest and Saint-Gilles +5342 Uccle/Watermael-Boitsfort/Auderghem: Auderghem, Uccle and Watermael-Boitsfort +5343 Montgomery: Etterbeek, Woluwe-Saint-Lambert and Woluwe-Saint-Pierre +5344 Polbruno: Evere, Saint-Josse-ten-Noode and Schaerbeek + +Fire department +The Brussels Fire and Emergency Medical Care Service, commonly known by its acronym SIAMU (DBDMH), operates in the 19 municipalities of Brussels. It is a class X fire department and the largest fire service in Belgium in terms of annual operations, equipment, and personnel. It has 9 fire stations, spread over the entire Brussels-Capital Region, and employs about 1,000 professional firefighters. As well as preventing and fighting fires, SIAMU also provides emergency medical care services in Brussels via its centralised 100 number (and the single 112 emergency number for the 27 countries of the European Union). It is bilingual (French–Dutch). + +Parks and green spaces + +Brussels is one of the greenest capitals in Europe, with over 8,000 hectares of green spaces. Vegetation cover and natural areas are higher in the outskirts, where they have limited the peri-urbanisation of the capital, but they decrease sharply towards the centre of Brussels; 10% in the central Pentagon, 30% of the municipalities in the first ring, and 71% of the municipalities in the second ring are occupied by green spaces. + +Many parks and gardens, both public and privately owned, are scattered throughout the city. In addition to this, the Sonian Forest is located in its southern part and stretches out over the three Belgian regions. , it has been inscribed as a UNESCO World Heritage Site, the only Belgian component to the multinational inscription 'Primeval Beech Forests of the Carpathians and Other Regions of Europe'. + +Notable people + +Twin towns – sister cities + +Brussels is twinned with the

Ten Nobel Prizes have been awarded for work completed at Bell Laboratories. + +Bell Labs had its origin in the complex corporate organization of the Bell System telephone conglomerate. The laboratory began in the late 19th century as the Western Electric Engineering Department, located at 463 West Street in New York City. After years of conducting research and development under Western Electric, a Bell subsidiary, the Engineering Department was reformed into Bell Telephone Laboratories in 1925 and placed under the shared ownership of Western Electric and the American Telephone and Telegraph Company (AT&T). In the 1960s, laboratory and company headquarters were moved to New Jersey. Nokia acquired Bell Labs in 2016. + +Origin and historical locations + +Bell's personal research after the telephone +In 1880, when the French government awarded Alexander Graham Bell the Volta Prize of 50,000francs for the invention of the telephone (equivalent to about US$10,000 at the time, or about $ now), he used the award to fund the Volta Laboratory (also known as the "Alexander Graham Bell Laboratory") in Washington, D.C. in collaboration with Sumner Tainter and Bell's cousin Chichester Bell. The laboratory was variously known as the Volta Bureau, the Bell Carriage House, the Bell Laboratory and the Volta Laboratory. + +It focused on the analysis, recording, and transmission of sound. Bell used his considerable profits from the laboratory for further research and education advancing the diffusion of knowledge relating to the deaf. This resulted in the founding of the Volta Bureau (c. 1887) at the Washington, D.C. home of his father, linguist Alexander Melville Bell. The carriage house there, at 1527 35th Street N.W., became their headquarters in 1889. + +In 1893, Bell constructed a new building close by at 1537 35th Street N.W., specifically to house the lab. This building was declared a National Historic Landmark in 1972. + +After the invention of the telephone, Bell maintained a relatively distant role with the Bell System as a whole, but continued to pursue his own personal research interests. + +Early antecedent +The Bell Patent Association was formed by Alexander Graham Bell, Thomas Sanders, and Gardiner Hubbard when filing the first patents for the telephone in 1876. + +Bell Telephone Company, the first telephone company, was formed a year later. It later became a part of the American Bell Telephone Company. + +In 1884, the American Bell Telephone Company created the Mechanical Department from the Electrical and Patent Department formed a year earlier. + +American Telephone & Telegraph Company (AT&T) and its own subsidiary company, took control of American Bell and the Bell System by 1889. + +American Bell held a controlling interest in Western Electric (which was the manufacturing arm of the business) whereas AT&T was doing research into the service providers. + +Formal organization and location changes + +In 1896, Western Electric bought property at 463 West Street to centralize the manufacturers and engineers which had been supplying AT&T with such technology as telephones, telephone exchange switches and transmission equipment. + +On January 1, 1925, Bell Telephone Laboratories, Inc. was organized to consolidate the development and research activities in the communication field and allied sciences for the Bell System. Ownership was evenly shared between Western Electric and AT&T. The new company had 3600 engineers, scientists, and support staff. Its 400,000 square foot space was expanded with a new building occupying about one quarter of a city block. + +The first chairman of the board of directors was John J. Carty, the vice-president of AT&T, and the first president was Frank B. Jewett, also a board member, who stayed there until 1940. The operations were directed by E. B. Craft, executive vice-president, and formerly chief engineer at Western Electric. + +By the early 1940s, Bell Labs engineers and scientists had begun to move to other locations away from the congestion and environmental distractions of New York City, and in 1967 Bell Laboratories headquarters was officially relocated to Murray Hill, New Jersey. + +Among the later Bell Laboratories locations in New Jersey were Holmdel, Crawford Hill, the Deal Test Site, Freehold, Lincroft, Long Branch, Middletown, Neptune, Princeton, Piscataway, Red Bank, Chester, and Whippany. Of these, Murray Hill and Crawford Hill remain in existence (the Piscataway and Red Bank locations were transferred to and are now operated by Telcordia Technologies and the Whippany site was purchased by Bayer). + +The largest grouping of people in the company was in Illinois, at Naperville-Lisle, in the Chicago area, which had the largest concentration of employees (about 11,000) prior to 2001. There also were groups of employees in Indianapolis, Indiana; Columbus, Ohio; North Andover, Massachusetts; Allentown, Pennsylvania; Reading, Pennsylvania; and Breinigsville, Pennsylvania; Burlington, North Carolina (1950s–1970s, moved to Greensboro 1980s) and Westminster, Colorado. Since 2001, many of the former locations have been scaled down or closed. + +Bell’s Holmdel research and development lab, a 1.9 million square foot structure set on 473 acres, was closed in 2007. The mirrored-glass building was designed by Eero Saarinen. In August 2013, Somerset Development bought the building, intending to redevelop it into a mixed commercial and residential project.

Shewhart proposed the control chart as a method to determine when a process was in a state of statistical control. Shewhart's methods were the basis for statistical process control (SPC): the use of statistically based tools and techniques to manage and improve processes. This was the origin of the modern quality control movement, including Six Sigma. + +In 1926, the laboratories invented an early synchronous-sound motion picture system, in competition with Fox Movietone and DeForest Phonofilm. + +In 1927, a Bell team headed by Herbert E. Ives successfully transmitted long-distance 128-line television images of Secretary of Commerce Herbert Hoover from Washington to New York. In 1928 the thermal noise in a resistor was first measured by John B. Johnson, for which Harry Nyquist provided the theoretical analysis; this is now termed Johnson noise. During the 1920s, the one-time pad cipher was invented by Gilbert Vernam and Joseph Mauborgne at the laboratories. Bell Labs' Claude Shannon later proved that it is unbreakable. + +In 1928, Harold Black invented the negative feedback system commonly used in amplifiers. Later, Harry Nyquist analyzed Black's design rule for negative feedback. This work was published in 1932 and became known as the Nyquist criterion. + +1930s + +In 1931, a foundation for radio astronomy was laid by Karl Jansky during his work investigating the origins of static on long-distance shortwave communications.

In 1947, Richard Hamming invented Hamming codes for error detection and correction. For patent reasons, the result was not published until 1950. + +In 1948, "A Mathematical Theory of Communication", one of the founding works in information theory, was published by Claude Shannon in the Bell System Technical Journal. It built in part on earlier work in the field by Bell researchers Harry Nyquist and Ralph Hartley, but it greatly extended these. Bell Labs also introduced a series of increasingly complex calculators through the decade. Shannon was also the founder of modern cryptography with his 1949 paper Communication Theory of Secrecy Systems. + +Calculators + + Model I: A complex number calculator, completed in 1939 and put into operation in 1940, for doing calculations of complex numbers. + Model II: Relay Computer / Relay Interpolator, September 1943, for interpolating data points of flight profiles (needed for performance testing of a gun director).

This technology evolution dramatically reduced floor space needs. The new ESS also came with its own diagnostic software that needed only a switchman and several frame technicians to maintain. + +About 1970, the coax-22 cable was developed by Bell Labs. This coax cable with 22 strands allowed a total capacity of 132,000 telephone calls. Previously, a 12-strand coax cable was used for L-carrier systems. Both of these types of cables were manufactured at Western Electrics' Baltimore Works facility on machines designed by a Western Electric Senior development engineer. + +In 1970, A.

Ritchie started in 1967 at Bell Labs in the Bell Labs Computer Systems Research department. Thompson started in 1966. Both co-inventors of the UNIX operating system and C language were also awarded decades later the 2011 Japan Prize for Information and Communications. + +In 1982, fractional quantum Hall effect was discovered by Horst Störmer and former Bell Laboratories researchers Robert B. Laughlin and Daniel C. Tsui; they consequently won a Nobel Prize in 1998 for the discovery. + +In 1984, the first photoconductive antennas for picosecond electromagnetic radiation were demonstrated by Auston and others. This type of antenna became an important component in terahertz time-domain spectroscopy. In 1984, Karmarkar's algorithm for linear programming was developed by mathematician Narendra Karmarkar. Also in 1984, a divestiture agreement signed in 1982 with the American Federal government forced the breakup of AT&T, and Bellcore (now iconectiv) was split off from Bell Laboratories to provide the same R&D functions for the newly created local exchange carriers. AT&T also was limited to using the Bell trademark only in association with Bell Laboratories. Bell Telephone Laboratories, Inc. became a wholly owned company of the new AT&T Technologies unit, the former Western Electric. The 5ESS Switch was developed during this transition. + +The National Medal of Technology was awarded to Bell Labs, the first corporation to achieve this honor in February 1985. + +In 1985, laser cooling was used to slow and manipulate atoms by Steven Chu and team.

Fail-safe and disaster-related traffic management operations systems enhanced the usefulness of the fiber optics. There was a synergy in the land-based and seas-based fiber optic systems, although they were developed by different divisions within the company. These systems are still in use throughout the U.S. today. + +Charles A. Burrus became a Bell Labs Fellow in 1988 for his work done as a Technical Staff member. Prior to this accomplishment, was awarded in 1982 the AT&T Bell Laboratories Distinguished Technical Staff Award.

Gitlin provided the foundational +technology to demonstrate that adaptive antenna arrays at the transmitter and receiver can +substantially increase both the reliability (via diversity) and capacity (via spatial multiplexing) of +wireless systems without expanding the bandwidth. Subsequently, the BLAST system proposed by Gerard Foschini and colleagues dramatically expanded the capacity of wireless systems. This technology, known today as MIMO (Multiple Input Multiple Output), was a significant factor in +the standardization, commercialization, performance improvement, and growth of +cellular and wireless LAN systems. + +Amos Joel in 1993 received the National Medal of Technology. + +Two AT&T Bell Labs scientists, Joel Engel and Richard Frenkiel, were honored with the National Medal of Technology, in 1994. + +In 1994, the quantum cascade laser was invented by Federico Capasso, Alfred Cho, Jerome Faist and their collaborators.

Kim, former President of Lucent's Optical Network Group, returned from academia to become the President of Bell Laboratories. + +In April 2006, Bell Laboratories' parent company, Lucent Technologies, signed a merger agreement with Alcatel. On December 1, 2006, the merged company, Alcatel-Lucent, began operations. This deal raised concerns in the United States, where Bell Laboratories works on defense contracts. A separate company, LGS Innovations, with an American board was set up to manage Bell Laboratories' and Lucent's sensitive U.S. government contracts. In March 2019, LGS Innovations was purchased by CACI. + +In December 2007, it was announced that the former Lucent Bell Laboratories and the former Alcatel Research and Innovation would be merged into one organization under the name of Bell Laboratories. This is the first period of growth following many years during which Bell Laboratories progressively lost manpower due to layoffs and spin-offs making the company shut down briefly. + +In February 2008, Alcatel-Lucent continued the Bell Laboratories tradition of awarding the prestigious award for outstanding technical contributors. Martin J. Glapa, a former chief Technical Officer of Lucent's Cable Communications Business Unit and Director of Advanced Technologies, was presented by Alcatel-Lucent Bell Labs President Jeong H. Kim with the 2006 Bell Labs Fellow Award in Network Architecture, Network Planning, and Professional Services with particular focus in Cable TV Systems and Broadband Services having "significant resulting Alcatel-Lucent commercial successes."

Stroustrup served as a visiting professor of computer science at Columbia University in the City of New York beginning in 2014, where he has been a full professor since 2022. + +Early life and education +Stroustrup was born in Aarhus, Denmark. His family was working class, and he attended local schools. + +He attended Aarhus University from 1969 to 1975 and graduated with a Candidatus Scientiarum in mathematics with computer science. His interests focused on microprogramming and machine architecture. He learned the fundamentals of object-oriented programming from its inventor, Kristen Nygaard, who frequently visited Aarhus. + +In 1979, he received his PhD in computer science from the University of Cambridge, where his research on distributed computing was supervised by David Wheeler. + +Career and research +In 1979, Stroustrup began his career as a member of technical staff in the Computer Science Research Center of Bell Labs in Murray Hill, New Jersey, USA. There, he began his work on C++ and programming techniques. Stroustrup was the head of AT&T Bell Labs' Large-scale Programming Research department, from its creation until late 2002. In 1993, he was made a Bell Labs fellow and in 1996, an AT&T Fellow. + +From 2002 to 2014, Stroustrup was the College of Engineering Chair Professor in Computer Science at Texas A&M University. From 2011, he was made a University Distinguished Professor. + +From January 2014 to April 2022, Stroustrup was a technical fellow and managing director in the technology division of Morgan Stanley in New York City and a visiting professor in computer science at Columbia University. + +As of July 2022, Stroustrup is a full professor of Computer Science at Columbia University. + +C++ + +Stroustrup is best known for his work on C++. In 1979, he began developing C++ (initially called "C with Classes"). In his own words, he "invented C++, wrote its early definitions, and produced its first implementation [...] chose and formulated the design criteria for C++, designed all its major facilities, and was responsible for the processing of extension proposals in the C++ standards committee." C++ was made generally available in 1985. For non-commercial use, the source code of the compiler and the foundation libraries was the cost of shipping (US$75); this was before Internet access was common. Stroustrup also published a textbook for the language in 1985, The C++ Programming Language. + +The key language-technical areas of contribution of C++ are: + + A static type system with equal support for built-in types and user-defined types (that requires control of the construction, destruction, copying, and movement of objects; and operator overloading). + Value and reference semantics. + Systematic and general resource management (RAII): constructors, destructor, and exceptions relying on them. + Support for efficient object-oriented programming: based on the Simula model with statically checked interfaces, multiple inheritance, and efficient implementation based on virtual function tables. + Support for flexible and efficient generic programming: templates with specialization and concepts. + Support for compile-time programming: template metaprogramming and compile-time evaluated functions ("constexpr functions"). + Direct use of machine and operating system resources. + Concurrency support through libraries (where necessary, implemented using intrinsics). + +Stroustrup documented his principles guiding the design of C++ and the evolution of the language in his 1994 book, The Design and Evolution of C++, and three papers for ACM's History of Programming Languages conferences. + +Stroustrup was a founding member of the C++ standards committee (from 1989, it was an ANSI committee and from 1991 an ISO committee) and has remained an active member ever since. For 24 years he chaired the subgroup chartered to handle proposals for language extensions (Evolution Working Group). + +Awards and honors +Selected honors + + 2018: The Charles Stark Draper Prize from The US National Academy of Engineering for conceptualizing and developing the C++ programming language. + 2018: The Computer Pioneer Award from The IEEE Computer Society for bringing object-oriented programming and generic programming to the mainstream with his design and implementation of the C++ programming language. + 2017: The Faraday Medal from the IET (Institute of Engineering Technology) for significant contributions to the history of computing, in particular pioneering the C++ programming language. + 2010: The University of Aarhus's Rigmor og Carl Holst-Knudsens Videnskabspris. + 2005: The William Procter Prize for Scientific Achievement from Sigma Xi (the scientific research society) as the first computer scientist ever. + 1993: The ACM Grace Murray Hopper award for his early work laying the foundations for the C++ programming language.

The brain is the largest cluster of neurons in the body and is typically located in the head, usually near organs for special senses such as vision, hearing and olfaction. It is the most specialized and energy-consuming organ in the body, responsible for complex sensory perception, motor control, endocrine regulation and the development of intelligence. + +While invertebrate brains arise from paired segmental ganglia (each of which is only responsible for the respective body segment) of the ventral nerve cord, vertebrate brains develop axially from the midline dorsal nerve cord as a vesicular enlargement at the rostral end of the neural tube, with centralized control over all body segments. All vertebrate brains can be embryonically divided into three parts: the forebrain (prosencephalon, subdivided into telencephalon and diencephalon), midbrain (mesencephalon) and hindbrain (rhombencephalon, subdivided into metencephalon and myelencephalon). The spinal cord, which directly interacts with somatic functions below the head, can be considered a caudal extension of the myelencephalon enclosed inside the vertebral column. Together, the brain and spinal cord constitute the central nervous system in all vertebrates. + +In humans, the cerebral cortex contains approximately 14–16 billion neurons, and the estimated number of neurons in the cerebellum is 55–70 billion. Each neuron is connected by synapses to several thousand other neurons, typically communicating with one another via root-like protrusions called dendrites and long fiber-like extensions called axons, which are usually myelinated and carry trains of rapid micro-electric signal pulses called action potentials to target specific recipient cells in other areas of the brain or distant parts of the body. The prefrontal cortex, which controls executive functions, is particularly well developed in humans. + +Physiologically, brains exert centralized control over a body's other organs. They act on the rest of the body both by generating patterns of muscle activity and by driving the secretion of chemicals called hormones. This centralized control allows rapid and coordinated responses to changes in the environment. Some basic types of responsiveness such as reflexes can be mediated by the spinal cord or peripheral ganglia, but sophisticated purposeful control of behavior based on complex sensory input requires the information integrating capabilities of a centralized brain. + +The operations of individual brain cells are now understood in considerable detail but the way they cooperate in ensembles of millions is yet to be solved. Recent models in modern neuroscience treat the brain as a biological computer, very different in mechanism from a digital computer, but similar in the sense that it acquires information from the surrounding world, stores it, and processes it in a variety of ways. + +This article compares the properties of brains across the entire range of animal species, with the greatest attention to vertebrates. It deals with the human brain insofar as it shares the properties of other brains. The ways in which the human brain differs from other brains are covered in the human brain article. Several topics that might be covered here are instead covered there because much more can be said about them in a human context. The most important that are covered in the human brain article are brain disease and the effects of brain damage. + +Anatomy + +The shape and size of the brain varies greatly between species, and identifying common features is often difficult. Nevertheless, there are a number of principles of brain architecture that apply across a wide range of species. Some aspects of brain structure are common to almost the entire range of animal species; others distinguish "advanced" brains from more primitive ones, or distinguish vertebrates from invertebrates. + +The simplest way to gain information about brain anatomy is by visual inspection, but many more sophisticated techniques have been developed. Brain tissue in its natural state is too soft to work with, but it can be hardened by immersion in alcohol or other fixatives, and then sliced apart for examination of the interior. Visually, the interior of the brain consists of areas of so-called grey matter, with a dark color, separated by areas of white matter, with a lighter color. Further information can be gained by staining slices of brain tissue with a variety of chemicals that bring out areas where specific types of molecules are present in high concentrations. It is also possible to examine the microstructure of brain tissue using a microscope, and to trace the pattern of connections from one brain area to another. + +Cellular structure + +The brains of all species are composed primarily of two broad classes of cells: neurons and glial cells. Glial cells (also known as glia or neuroglia) come in several types, and perform a number of critical functions, including structural support, metabolic support, insulation, and guidance of development. Neurons, however, are usually considered the most important cells in the brain. +The property that makes neurons unique is their ability to send signals to specific target cells over long distances. They send these signals by means of an axon, which is a thin protoplasmic fiber that extends from the cell body and projects, usually with numerous branches, to other areas, sometimes nearby, sometimes in distant parts of the brain or body. The length of an axon can be extraordinary: for example, if a pyramidal cell (an excitatory neuron) of the cerebral cortex were magnified so that its cell body became the size of a human body, its axon, equally magnified, would become a cable a few centimeters in diameter, extending more than a kilometer. These axons transmit signals in the form of electrochemical pulses called action potentials, which last less than a thousandth of a second and travel along the axon at speeds of 1–100 meters per second. Some neurons emit action potentials constantly, at rates of 10–100 per second, usually in irregular patterns; other neurons are quiet most of the time, but occasionally emit a burst of action potentials. + +Axons transmit signals to other neurons by means of specialized junctions called synapses. A single axon may make as many as several thousand synaptic connections with other cells. When an action potential, traveling along an axon, arrives at a synapse, it causes a chemical called a neurotransmitter to be released. The neurotransmitter binds to receptor molecules in the membrane of the target cell. + +Synapses are the key functional elements of the brain. The essential function of the brain is cell-to-cell communication, and synapses are the points at which communication occurs. The human brain has been estimated to contain approximately 100 trillion synapses; even the brain of a fruit fly contains several million. The functions of these synapses are very diverse: some are excitatory (exciting the target cell); others are inhibitory; others work by activating second messenger systems that change the internal chemistry of their target cells in complex ways. A large number of synapses are dynamically modifiable; that is, they are capable of changing strength in a way that is controlled by the patterns of signals that pass through them. It is widely believed that activity-dependent modification of synapses is the brain's primary mechanism for learning and memory. + +Most of the space in the brain is taken up by axons, which are often bundled together in what are called nerve fiber tracts. A myelinated axon is wrapped in a fatty insulating sheath of myelin, which serves to greatly increase the speed of signal propagation. (There are also unmyelinated axons). Myelin is white, making parts of the brain filled exclusively with nerve fibers appear as light-colored white matter, in contrast to the darker-colored grey matter that marks areas with high densities of neuron cell bodies. + +Evolution + +Generic bilaterian nervous system + +Except for a few primitive organisms such as sponges (which have no nervous system) and cnidarians (which have a diffuse nervous system consisting of a nerve net), all living multicellular animals are bilaterians, meaning animals with a bilaterally symmetric body plan (that is, left and right sides that are approximate mirror images of each other). All bilaterians are thought to have descended from a common ancestor that appeared late in the Cryogenian period, 700–650 million years ago, and it has been hypothesized that this common ancestor had the shape of a simple tubeworm with a segmented body. At a schematic level, that basic worm-shape continues to be reflected in the body and nervous system architecture of all modern bilaterians, including vertebrates. The fundamental bilateral body form is a tube with a hollow gut cavity running from the mouth to the anus, and a nerve cord with an enlargement (a ganglion) for each body segment, with an especially large ganglion at the front, called the brain. The brain is small and simple in some species, such as nematode worms; in other species, including vertebrates, it is the most complex organ in the body. Some types of worms, such as leeches, also have an enlarged ganglion at the back end of the nerve cord, known as a "tail brain". + +There are a few types of existing bilaterians that lack a recognizable brain, including echinoderms and tunicates. It has not been definitively established whether the existence of these brainless species indicates that the earliest bilaterians lacked a brain, or whether their ancestors evolved in a way that led to the disappearance of a previously existing brain structure. + +Invertebrates + +This category includes tardigrades, arthropods, molluscs, and numerous types of worms. The diversity of invertebrate body plans is matched by an equal diversity in brain structures. + +Two groups of invertebrates have notably complex brains: arthropods (insects, crustaceans, arachnids, and others), and cephalopods (octopuses, squids, and similar molluscs). The brains of arthropods and cephalopods arise from twin parallel nerve cords that extend through the body of the animal. Arthropods have a central brain, the supraesophageal ganglion, with three divisions and large optical lobes behind each eye for visual processing. Cephalopods such as the octopus and squid have the largest brains of any invertebrates. + +There are several invertebrate species whose brains have been studied intensively because they have properties that make them convenient for experimental work: + Fruit flies (Drosophila), because of the large array of techniques available for studying their genetics, have been a natural subject for studying the role of genes in brain development. In spite of the large evolutionary distance between insects and mammals, many aspects of Drosophila neurogenetics have been shown to be relevant to humans. The first biological clock genes, for example, were identified by examining Drosophila mutants that showed disrupted daily activity cycles. A search in the genomes of vertebrates revealed a set of analogous genes, which were found to play similar roles in the mouse biological clock—and therefore almost certainly in the human biological clock as well. Studies done on Drosophila, also show that most neuropil regions of the brain are continuously reorganized throughout life in response to specific living conditions. + The nematode worm Caenorhabditis elegans, like Drosophila, has been studied largely because of its importance in genetics. In the early 1970s, Sydney Brenner chose it as a model organism for studying the way that genes control development. One of the advantages of working with this worm is that the body plan is very stereotyped: the nervous system of the hermaphrodite contains exactly 302 neurons, always in the same places, making identical synaptic connections in every worm. Brenner's team sliced worms into thousands of ultrathin sections and photographed each one under an electron microscope, then visually matched fibers from section to section, to map out every neuron and synapse in the entire body. The complete neuronal wiring diagram of C.elegans – its connectome was achieved. Nothing approaching this level of detail is available for any other organism, and the information gained has enabled a multitude of studies that would otherwise have not been possible. + The sea slug Aplysia californica was chosen by Nobel Prize-winning neurophysiologist Eric Kandel as a model for studying the cellular basis of learning and memory, because of the simplicity and accessibility of its nervous system, and it has been examined in hundreds of experiments. + +Vertebrates + +The first vertebrates appeared over 500 million years ago (Mya), during the Cambrian period, and may have resembled the modern hagfish in form. Jawed fish appeared by 445 Mya, amphibians by 350 Mya, reptiles by 310 Mya and mammals by 200 Mya (approximately). Each species has an equally long evolutionary history, but the brains of modern hagfishes, lampreys, sharks, amphibians, reptiles, and mammals show a gradient of size and complexity that roughly follows the evolutionary sequence. All of these brains contain the same set of basic anatomical components, but many are rudimentary in the hagfish, whereas in mammals the foremost part (the telencephalon) is greatly elaborated and expanded. + +Brains are most commonly compared in terms of their size. The relationship between brain size, body size and other variables has been studied across a wide range of vertebrate species. As a rule, brain size increases with body size, but not in a simple linear proportion. In general, smaller animals tend to have larger brains, measured as a fraction of body size. For mammals, the relationship between brain volume and body mass essentially follows a power law with an exponent of about 0.75. This formula describes the central tendency, but every family of mammals departs from it to some degree, in a way that reflects in part the complexity of their behavior. For example, primates have brains 5 to 10 times larger than the formula predicts. Predators tend to have larger brains than their prey, relative to body size. + +All vertebrate brains share a common underlying form, which appears most clearly during early stages of embryonic development. In its earliest form, the brain appears as three swellings at the front end of the neural tube; these swellings eventually become the forebrain, midbrain, and hindbrain (the prosencephalon, mesencephalon, and rhombencephalon, respectively). At the earliest stages of brain development, the three areas are roughly equal in size. In many classes of vertebrates, such as fish and amphibians, the three parts remain similar in size in the adult, but in mammals the forebrain becomes much larger than the other parts, and the midbrain becomes very small. + +The brains of vertebrates are made of very soft tissue. Living brain tissue is pinkish on the outside and mostly white on the inside, with subtle variations in color. Vertebrate brains are surrounded by a system of connective tissue membranes called meninges that separate the skull from the brain. Blood vessels enter the central nervous system through holes in the meningeal layers. The cells in the blood vessel walls are joined tightly to one another, forming the blood–brain barrier, which blocks the passage of many toxins and pathogens (though at the same time blocking antibodies and some drugs, thereby presenting special challenges in treatment of diseases of the brain). + +Neuroanatomists usually divide the vertebrate brain into six main regions: the telencephalon (cerebral hemispheres), diencephalon (thalamus and hypothalamus), mesencephalon (midbrain), cerebellum, pons, and medulla oblongata. Each of these areas has a complex internal structure. Some parts, such as the cerebral cortex and the cerebellar cortex, consist of layers that are folded or convoluted to fit within the available space. Other parts, such as the thalamus and hypothalamus, consist of clusters of many small nuclei. Thousands of distinguishable areas can be identified within the vertebrate brain based on fine distinctions of neural structure, chemistry, and connectivity. + +Although the same basic components are present in all vertebrate brains, some branches of vertebrate evolution have led to substantial distortions of brain geometry, especially in the forebrain area. The brain of a shark shows the basic components in a straightforward way, but in teleost fishes (the great majority of existing fish species), the forebrain has become "everted", like a sock turned inside out. In birds, there are also major changes in forebrain structure. These distortions can make it difficult to match brain components from one species with those of another species. + +Here is a list of some of the most important vertebrate brain components, along with a brief description of their functions as currently understood: + + The medulla, along with the spinal cord, contains many small nuclei involved in a wide variety of sensory and involuntary motor functions such as vomiting, heart rate and digestive processes. + The pons lies in the brainstem directly above the medulla. Among other things, it contains nuclei that control often voluntary but simple acts such as sleep, respiration, swallowing, bladder function, equilibrium, eye movement, facial expressions, and posture. + The hypothalamus is a small region at the base of the forebrain, whose complexity and importance belies its size. It is composed of numerous small nuclei, each with distinct connections and neurochemistry. The hypothalamus is engaged in additional involuntary or partially voluntary acts such as sleep and wake cycles, eating and drinking, and the release of some hormones. + The thalamus is a collection of nuclei with diverse functions: some are involved in relaying information to and from the cerebral hemispheres, while others are involved in motivation. The subthalamic area (zona incerta) seems to contain action-generating systems for several types of "consummatory" behaviors such as eating, drinking, defecation, and copulation. + The cerebellum modulates the outputs of other brain systems, whether motor-related or thought related, to make them certain and precise. Removal of the cerebellum does not prevent an animal from doing anything in particular, but it makes actions hesitant and clumsy. This precision is not built-in but learned by trial and error. The muscle coordination learned while riding a bicycle is an example of a type of neural plasticity that may take place largely within the cerebellum. 10% of the brain's total volume consists of the cerebellum and 50% of all neurons are held within its structure. + The optic tectum allows actions to be directed toward points in space, most commonly in response to visual input. In mammals, it is usually referred to as the superior colliculus, and its best-studied function is to direct eye movements. It also directs reaching movements and other object-directed actions. It receives strong visual inputs, but also inputs from other senses that are useful in directing actions, such as auditory input in owls and input from the thermosensitive pit organs in snakes. In some primitive fishes, such as lampreys, this region is the largest part of the brain. The superior colliculus is part of the midbrain. + The pallium is a layer of grey matter that lies on the surface of the forebrain and is the most complex and most recent evolutionary development of the brain as an organ. In reptiles and mammals, it is called the cerebral cortex. Multiple functions involve the pallium, including smell and spatial memory. In mammals, where it becomes so large as to dominate the brain, it takes over functions from many other brain areas. In many mammals, the cerebral cortex consists of folded bulges called gyri that create deep furrows or fissures called sulci. The folds increase the surface area of the cortex and therefore increase the amount of gray matter and the amount of information that can be stored and processed. + The hippocampus, strictly speaking, is found only in mammals. However, the area it derives from, the medial pallium, has counterparts in all vertebrates. There is evidence that this part of the brain is involved in complex events such as spatial memory and navigation in fishes, birds, reptiles, and mammals. + The basal ganglia are a group of interconnected structures in the forebrain. The primary function of the basal ganglia appears to be action selection: they send inhibitory signals to all parts of the brain that can generate motor behaviors, and in the right circumstances can release the inhibition, so that the action-generating systems are able to execute their actions. Reward and punishment exert their most important neural effects by altering connections within the basal ganglia. + The olfactory bulb is a special structure that processes olfactory sensory signals and sends its output to the olfactory part of the pallium. It is a major brain component in many vertebrates, but is greatly reduced in humans and other primates (whose senses are dominated by information acquired by sight rather than smell). + +Reptiles + +Reptiles have a brain. + +Birds + +Mammals +The most obvious difference between the brains of mammals and other vertebrates is in terms of size. On average, a mammal has a brain roughly twice as large as that of a bird of the same body size, and ten times as large as that of a reptile of the same body size. + +Size, however, is not the only difference: there are also substantial differences in shape. The hindbrain and midbrain of mammals are generally similar to those of other vertebrates, but dramatic differences appear in the forebrain, which is greatly enlarged and also altered in structure. The cerebral cortex is the part of the brain that most strongly distinguishes mammals. In non-mammalian vertebrates, the surface of the cerebrum is lined with a comparatively simple three-layered structure called the pallium. In mammals, the pallium evolves into a complex six-layered structure called neocortex or isocortex. Several areas at the edge of the neocortex, including the hippocampus and amygdala, are also much more extensively developed in mammals than in other vertebrates. + +The elaboration of the cerebral cortex carries with it changes to other brain areas. The superior colliculus, which plays a major role in visual control of behavior in most vertebrates, shrinks to a small size in mammals, and many of its functions are taken over by visual areas of the cerebral cortex. The cerebellum of mammals contains a large portion (the neocerebellum) dedicated to supporting the cerebral cortex, which has no counterpart in other vertebrates. + +Primates + +The brains of humans and other primates contain the same structures as the brains of other mammals, but are generally larger in proportion to body size. The encephalization quotient (EQ) is used to compare brain sizes across species. It takes into account the nonlinearity of the brain-to-body relationship. Humans have an average EQ in the 7-to-8 range, while most other primates have an EQ in the 2-to-3 range. Dolphins have values higher than those of primates other than humans, but nearly all other mammals have EQ values that are substantially lower. + +Most of the enlargement of the primate brain comes from a massive expansion of the cerebral cortex, especially the prefrontal cortex and the parts of the cortex involved in vision. The visual processing network of primates includes at least 30 distinguishable brain areas, with a complex web of interconnections. It has been estimated that visual processing areas occupy more than half of the total surface of the primate neocortex. The prefrontal cortex carries out functions that include planning, working memory, motivation, attention, and executive control. It takes up a much larger proportion of the brain for primates than for other species, and an especially large fraction of the human brain. + +Development + +The brain develops in an intricately orchestrated sequence of stages. It changes in shape from a simple swelling at the front of the nerve cord in the earliest embryonic stages, to a complex array of areas and connections. Neurons are created in special zones that contain stem cells, and then migrate through the tissue to reach their ultimate locations. Once neurons have positioned themselves, their axons sprout and navigate through the brain, branching and extending as they go, until the tips reach their targets and form synaptic connections. In a number of parts of the nervous system, neurons and synapses are produced in excessive numbers during the early stages, and then the unneeded ones are pruned away. + +For vertebrates, the early stages of neural development are similar across all species. As the embryo transforms from a round blob of cells into a wormlike structure, a narrow strip of ectoderm running along the midline of the back is induced to become the neural plate, the precursor of the nervous system. The neural plate folds inward to form the neural groove, and then the lips that line the groove merge to enclose the neural tube, a hollow cord of cells with a fluid-filled ventricle at the center. At the front end, the ventricles and cord swell to form three vesicles that are the precursors of the prosencephalon (forebrain), mesencephalon (midbrain), and rhombencephalon (hindbrain). At the next stage, the forebrain splits into two vesicles called the telencephalon (which will contain the cerebral cortex, basal ganglia, and related structures) and the diencephalon (which will contain the thalamus and hypothalamus). At about the same time, the hindbrain splits into the metencephalon (which will contain the cerebellum and pons) and the myelencephalon (which will contain the medulla oblongata). Each of these areas contains proliferative zones where neurons and glial cells are generated; the resulting cells then migrate, sometimes for long distances, to their final positions. + +Once a neuron is in place, it extends dendrites and an axon into the area around it. Axons, because they commonly extend a great distance from the cell body and need to reach specific targets, grow in a particularly complex way. The tip of a growing axon consists of a blob of protoplasm called a growth cone, studded with chemical receptors. These receptors sense the local environment, causing the growth cone to be attracted or repelled by various cellular elements, and thus to be pulled in a particular direction at each point along its path. The result of this pathfinding process is that the growth cone navigates through the brain until it reaches its destination area, where other chemical cues cause it to begin generating synapses. Considering the entire brain, thousands of genes create products that influence axonal pathfinding. + +The synaptic network that finally emerges is only partly determined by genes, though. In many parts of the brain, axons initially "overgrow", and then are "pruned" by mechanisms that depend on neural activity. In the projection from the eye to the midbrain, for example, the structure in the adult contains a very precise mapping, connecting each point on the surface of the retina to a corresponding point in a midbrain layer. In the first stages of development, each axon from the retina is guided to the right general vicinity in the midbrain by chemical cues, but then branches very profusely and makes initial contact with a wide swath of midbrain neurons. The retina, before birth, contains special mechanisms that cause it to generate waves of activity that originate spontaneously at a random point and then propagate slowly across the retinal layer. These waves are useful because they cause neighboring neurons to be active at the same time; that is, they produce a neural activity pattern that contains information about the spatial arrangement of the neurons. This information is exploited in the midbrain by a mechanism that causes synapses to weaken, and eventually vanish, if activity in an axon is not followed by activity of the target cell. The result of this sophisticated process is a gradual tuning and tightening of the map, leaving it finally in its precise adult form. + +Similar things happen in other brain areas: an initial synaptic matrix is generated as a result of genetically determined chemical guidance, but then gradually refined by activity-dependent mechanisms, partly driven by internal dynamics, partly by external sensory inputs. In some cases, as with the retina-midbrain system, activity patterns depend on mechanisms that operate only in the developing brain, and apparently exist solely to guide development. + +In humans and many other mammals, new neurons are created mainly before birth, and the infant brain contains substantially more neurons than the adult brain. There are, however, a few areas where new neurons continue to be generated throughout life. The two areas for which adult neurogenesis is well established are the olfactory bulb, which is involved in the sense of smell, and the dentate gyrus of the hippocampus, where there is evidence that the new neurons play a role in storing newly acquired memories. With these exceptions, however, the set of neurons that is present in early childhood is the set that is present for life. Glial cells are different: as with most types of cells in the body, they are generated throughout the lifespan. + +There has long been debate about whether the qualities of mind, personality, and intelligence can be attributed to heredity or to upbringing—this is the nature and nurture controversy. Although many details remain to be settled, neuroscience research has clearly shown that both factors are important. Genes determine the general form of the brain, and genes determine how the brain reacts to experience. Experience, however, is required to refine the matrix of synaptic connections, which in its developed form contains far more information than the genome does. In some respects, all that matters is the presence or absence of experience during critical periods of development. In other respects, the quantity and quality of experience are important; for example, there is substantial evidence that animals raised in enriched environments have thicker cerebral cortices, indicating a higher density of synaptic connections, than animals whose levels of stimulation are restricted. + +Physiology +The functions of the brain depend on the ability of neurons to transmit electrochemical signals to other cells, and their ability to respond appropriately to electrochemical signals received from other cells. The electrical properties of neurons are controlled by a wide variety of biochemical and metabolic processes, most notably the interactions between neurotransmitters and receptors that take place at synapses. + +Neurotransmitters and receptors +Neurotransmitters are chemicals that are released at synapses when the local membrane is depolarised and Ca2+ enters into the cell, typically when an action potential arrives at the synapse – neurotransmitters attach themselves to receptor molecules on the membrane of the synapse's target cell (or cells), and thereby alter the electrical or chemical properties of the receptor molecules. With few exceptions, each neuron in the brain releases the same chemical neurotransmitter, or combination of neurotransmitters, at all the synaptic connections it makes with other neurons; this rule is known as Dale's principle. Thus, a neuron can be characterized by the neurotransmitters that it releases. The great majority of psychoactive drugs exert their effects by altering specific neurotransmitter systems. This applies to drugs such as cannabinoids, nicotine, heroin, cocaine, alcohol, fluoxetine, chlorpromazine, and many others. + +The two neurotransmitters that are most widely found in the vertebrate brain are glutamate, which almost always exerts excitatory effects on target neurons, and gamma-aminobutyric acid (GABA), which is almost always inhibitory. Neurons using these transmitters can be found in nearly every part of the brain. Because of their ubiquity, drugs that act on glutamate or GABA tend to have broad and powerful effects. Some general anesthetics act by reducing the effects of glutamate; most tranquilizers exert their sedative effects by enhancing the effects of GABA. + +There are dozens of other chemical neurotransmitters that are used in more limited areas of the brain, often areas dedicated to a particular function. Serotonin, for example—the primary target of many antidepressant drugs and many dietary aids—comes exclusively from a small brainstem area called the raphe nuclei. Norepinephrine, which is involved in arousal, comes exclusively from a nearby small area called the locus coeruleus. Other neurotransmitters such as acetylcholine and dopamine have multiple sources in the brain but are not as ubiquitously distributed as glutamate and GABA. + +Electrical activity + +As a side effect of the electrochemical processes used by neurons for signaling, brain tissue generates electric fields when it is active. When large numbers of neurons show synchronized activity, the electric fields that they generate can be large enough to detect outside the skull, using electroencephalography (EEG) or magnetoencephalography (MEG). EEG recordings, along with recordings made from electrodes implanted inside the brains of animals such as rats, show that the brain of a living animal is constantly active, even during sleep. Each part of the brain shows a mixture of rhythmic and nonrhythmic activity, which may vary according to behavioral state. In mammals, the cerebral cortex tends to show large slow delta waves during sleep, faster alpha waves when the animal is awake but inattentive, and chaotic-looking irregular activity when the animal is actively engaged in a task, called beta and gamma waves. During an epileptic seizure, the brain's inhibitory control mechanisms fail to function and electrical activity rises to pathological levels, producing EEG traces that show large wave and spike patterns not seen in a healthy brain. Relating these population-level patterns to the computational functions of individual neurons is a major focus of current research in neurophysiology. + +Metabolism +All vertebrates have a blood–brain barrier that allows metabolism inside the brain to operate differently from metabolism in other parts of the body. The neurovascular unit regulates cerebral blood flow so that activated neurons can be supplied with energy. Glial cells play a major role in brain metabolism by controlling the chemical composition of the fluid that surrounds neurons, including levels of ions and nutrients. + +Brain tissue consumes a large amount of energy in proportion to its volume, so large brains place severe metabolic demands on animals. The need to limit body weight in order, for example, to fly, has apparently led to selection for a reduction of brain size in some species, such as bats. Most of the brain's energy consumption goes into sustaining the electric charge (membrane potential) of neurons. Most vertebrate species devote between 2% and 8% of basal metabolism to the brain. In primates, however, the percentage is much higher—in humans it rises to 20–25%. The energy consumption of the brain does not vary greatly over time, but active regions of the cerebral cortex consume somewhat more energy than inactive regions; this forms the basis for the functional brain imaging methods of PET, fMRI, and NIRS. The brain typically gets most of its energy from oxygen-dependent metabolism of glucose (i.e., blood sugar), but ketones provide a major alternative source, together with contributions from medium chain fatty acids (caprylic and heptanoic acids), lactate, acetate, and possibly amino acids. + +Function + +Information from the sense organs is collected in the brain. There it is used to determine what actions the organism is to take. The brain processes the raw data to extract information about the structure of the environment. Next it combines the processed information with information about the current needs of the animal and with memory of past circumstances. Finally, on the basis of the results, it generates motor response patterns. These signal-processing tasks require intricate interplay between a variety of functional subsystems. + +The function of the brain is to provide coherent control over the actions of an animal. A centralized brain allows groups of muscles to be co-activated in complex patterns; it also allows stimuli impinging on one part of the body to evoke responses in other parts, and it can prevent different parts of the body from acting at cross-purposes to each other. + +Perception + +The human brain is provided with information about light, sound, the chemical composition of the atmosphere, temperature, the position of the body in space (proprioception), the chemical composition of the bloodstream, and more. In other animals additional senses are present, such as the infrared heat-sense of snakes, the magnetic field sense of some birds, or the electric field sense mainly seen in aquatic animals. + +Each sensory system begins with specialized receptor cells, such as photoreceptor cells in the retina of the eye, or vibration-sensitive hair cells in the cochlea of the ear. The axons of sensory receptor cells travel into the spinal cord or brain, where they transmit their signals to a first-order sensory nucleus dedicated to one specific sensory modality. This primary sensory nucleus sends information to higher-order sensory areas that are dedicated to the same modality. Eventually, via a way-station in the thalamus, the signals are sent to the cerebral cortex, where they are processed to extract the relevant features, and integrated with signals coming from other sensory systems. + +Motor control +Motor systems are areas of the brain that are involved in initiating body movements, that is, in activating muscles. Except for the muscles that control the eye, which are driven by nuclei in the midbrain, all the voluntary muscles in the body are directly innervated by motor neurons in the spinal cord and hindbrain. Spinal motor neurons are controlled both by neural circuits intrinsic to the spinal cord, and by inputs that descend from the brain. The intrinsic spinal circuits implement many reflex responses, and contain pattern generators for rhythmic movements such as walking or swimming. The descending connections from the brain allow for more sophisticated control. + +The brain contains several motor areas that project directly to the spinal cord. At the lowest level are motor areas in the medulla and pons, which control stereotyped movements such as walking, breathing, or swallowing. At a higher level are areas in the midbrain, such as the red nucleus, which is responsible for coordinating movements of the arms and legs. At a higher level yet is the primary motor cortex, a strip of tissue located at the posterior edge of the frontal lobe. The primary motor cortex sends projections to the subcortical motor areas, but also sends a massive projection directly to the spinal cord, through the pyramidal tract. This direct corticospinal projection allows for precise voluntary control of the fine details of movements. Other motor-related brain areas exert secondary effects by projecting to the primary motor areas. Among the most important secondary areas are the premotor cortex, supplementary motor area, basal ganglia, and cerebellum. In addition to all of the above, the brain and spinal cord contain extensive circuitry to control the autonomic nervous system which controls the movement of the smooth muscle of the body. + +Sleep + +Many animals alternate between sleeping and waking in a daily cycle. Arousal and alertness are also modulated on a finer time scale by a network of brain areas. A key component of the sleep system is the suprachiasmatic nucleus (SCN), a tiny part of the hypothalamus located directly above the point at which the optic nerves from the two eyes cross. The SCN contains the body's central biological clock. Neurons there show activity levels that rise and fall with a period of about 24 hours, circadian rhythms: these activity fluctuations are driven by rhythmic changes in expression of a set of "clock genes". The SCN continues to keep time even if it is excised from the brain and placed in a dish of warm nutrient solution, but it ordinarily receives input from the optic nerves, through the retinohypothalamic tract (RHT), that allows daily light-dark cycles to calibrate the clock. + +The SCN projects to a set of areas in the hypothalamus, brainstem, and midbrain that are involved in implementing sleep-wake cycles. An important component of the system is the reticular formation, a group of neuron-clusters scattered diffusely through the core of the lower brain. Reticular neurons send signals to the thalamus, which in turn sends activity-level-controlling signals to every part of the cortex. Damage to the reticular formation can produce a permanent state of coma. + +Sleep involves great changes in brain activity. Until the 1950s it was generally believed that the brain essentially shuts off during sleep, but this is now known to be far from true; activity continues, but patterns become very different. There are two types of sleep: REM sleep (with dreaming) and NREM (non-REM, usually without dreaming) sleep, which repeat in slightly varying patterns throughout a sleep episode. Three broad types of distinct brain activity patterns can be measured: REM, light NREM and deep NREM. During deep NREM sleep, also called slow wave sleep, activity in the cortex takes the form of large synchronized waves, whereas in the waking state it is noisy and desynchronized. Levels of the neurotransmitters norepinephrine and serotonin drop during slow wave sleep, and fall almost to zero during REM sleep; levels of acetylcholine show the reverse pattern. + +Homeostasis + +For any animal, survival requires maintaining a variety of parameters of bodily state within a limited range of variation: these include temperature, water content, salt concentration in the bloodstream, blood glucose levels, blood oxygen level, and others. The ability of an animal to regulate the internal environment of its body—the milieu intérieur, as the pioneering physiologist Claude Bernard called it—is known as homeostasis (Greek for "standing still"). Maintaining homeostasis is a crucial function of the brain. The basic principle that underlies homeostasis is negative feedback: any time a parameter diverges from its set-point, sensors generate an error signal that evokes a response that causes the parameter to shift back toward its optimum value. (This principle is widely used in engineering, for example in the control of temperature using a thermostat.) + +In vertebrates, the part of the brain that plays the greatest role is the hypothalamus, a small region at the base of the forebrain whose size does not reflect its complexity or the importance of its function. The hypothalamus is a collection of small nuclei, most of which are involved in basic biological functions. Some of these functions relate to arousal or to social interactions such as sexuality, aggression, or maternal behaviors; but many of them relate to homeostasis. Several hypothalamic nuclei receive input from sensors located in the lining of blood vessels, conveying information about temperature, sodium level, glucose level, blood oxygen level, and other parameters. These hypothalamic nuclei send output signals to motor areas that can generate actions to rectify deficiencies. Some of the outputs also go to the pituitary gland, a tiny gland attached to the brain directly underneath the hypothalamus. The pituitary gland secretes hormones into the bloodstream, where they circulate throughout the body and induce changes in cellular activity. + +Motivation + +The individual animals need to express survival-promoting behaviors, such as seeking food, water, shelter, and a mate. The motivational system in the brain monitors the current state of satisfaction of these goals, and activates behaviors to meet any needs that arise. The motivational system works largely by a reward–punishment mechanism. When a particular behavior is followed by favorable consequences, the reward mechanism in the brain is activated, which induces structural changes inside the brain that cause the same behavior to be repeated later, whenever a similar situation arises. Conversely, when a behavior is followed by unfavorable consequences, the brain's punishment mechanism is activated, inducing structural changes that cause the behavior to be suppressed when similar situations arise in the future. + +Most organisms studied to date use a reward–punishment mechanism: for instance, worms and insects can alter their behavior to seek food sources or to avoid dangers. In vertebrates, the reward-punishment system is implemented by a specific set of brain structures, at the heart of which lie the basal ganglia, a set of interconnected areas at the base of the forebrain. The basal ganglia are the central site at which decisions are made: the basal ganglia exert a sustained inhibitory control over most of the motor systems in the brain; when this inhibition is released, a motor system is permitted to execute the action it is programmed to carry out. Rewards and punishments function by altering the relationship between the inputs that the basal ganglia receive and the decision-signals that are emitted. The reward mechanism is better understood than the punishment mechanism, because its role in drug abuse has caused it to be studied very intensively. Research has shown that the neurotransmitter dopamine plays a central role: addictive drugs such as cocaine, amphetamine, and nicotine either cause dopamine levels to rise or cause the effects of dopamine inside the brain to be enhanced. + +Learning and memory +Almost all animals are capable of modifying their behavior as a result of experience—even the most primitive types of worms. Because behavior is driven by brain activity, changes in behavior must somehow correspond to changes inside the brain. Already in the late 19th century theorists like Santiago Ramón y Cajal argued that the most plausible explanation is that learning and memory are expressed as changes in the synaptic connections between neurons. Until 1970, however, experimental evidence to support the synaptic plasticity hypothesis was lacking. In 1971 Tim Bliss and Terje Lømo published a paper on a phenomenon now called long-term potentiation: the paper showed clear evidence of activity-induced synaptic changes that lasted for at least several days. Since then technical advances have made these sorts of experiments much easier to carry out, and thousands of studies have been made that have clarified the mechanism of synaptic change, and uncovered other types of activity-driven synaptic change in a variety of brain areas, including the cerebral cortex, hippocampus, basal ganglia, and cerebellum. Brain-derived neurotrophic factor (BDNF) and physical activity appear to play a beneficial role in the process. + +Neuroscientists currently distinguish several types of learning and memory that are implemented by the brain in distinct ways: + + Working memory is the ability of the brain to maintain a temporary representation of information about the task that an animal is currently engaged in. This sort of dynamic memory is thought to be mediated by the formation of cell assemblies—groups of activated neurons that maintain their activity by constantly stimulating one another. + Episodic memory is the ability to remember the details of specific events. This sort of memory can last for a lifetime. Much evidence implicates the hippocampus in playing a crucial role: people with severe damage to the hippocampus sometimes show amnesia, that is, inability to form new long-lasting episodic memories. + Semantic memory is the ability to learn facts and relationships. This sort of memory is probably stored largely in the cerebral cortex, mediated by changes in connections between cells that represent specific types of information. + Instrumental learning is the ability for rewards and punishments to modify behavior. It is implemented by a network of brain areas centered on the basal ganglia. + Motor learning is the ability to refine patterns of body movement by practicing, or more generally by repetition. A number of brain areas are involved, including the premotor cortex, basal ganglia, and especially the cerebellum, which functions as a large memory bank for microadjustments of the parameters of movement. + +Research + +The field of neuroscience encompasses all approaches that seek to understand the brain and the rest of the nervous system. Psychology seeks to understand mind and behavior, and neurology is the medical discipline that diagnoses and treats diseases of the nervous system. The brain is also the most important organ studied in psychiatry, the branch of medicine that works to study, prevent, and treat mental disorders. Cognitive science seeks to unify neuroscience and psychology with other fields that concern themselves with the brain, such as computer science (artificial intelligence and similar fields) and philosophy. + +The oldest method of studying the brain is anatomical, and until the middle of the 20th century, much of the progress in neuroscience came from the development of better cell stains and better microscopes. Neuroanatomists study the large-scale structure of the brain as well as the microscopic structure of neurons and their components, especially synapses. Among other tools, they employ a plethora of stains that reveal neural structure, chemistry, and connectivity. In recent years, the development of immunostaining techniques has allowed investigation of neurons that express specific sets of genes. Also, functional neuroanatomy uses medical imaging techniques to correlate variations in human brain structure with differences in cognition or behavior. + +Neurophysiologists study the chemical, pharmacological, and electrical properties of the brain: their primary tools are drugs and recording devices. Thousands of experimentally developed drugs affect the nervous system, some in highly specific ways. Recordings of brain activity can be made using electrodes, either glued to the scalp as in EEG studies, or implanted inside the brains of animals for extracellular recordings, which can detect action potentials generated by individual neurons. Because the brain does not contain pain receptors, it is possible using these techniques to record brain activity from animals that are awake and behaving without causing distress. The same techniques have occasionally been used to study brain activity in human patients with intractable epilepsy, in cases where there was a medical necessity to implant electrodes to localize the brain area responsible for epileptic seizures. Functional imaging techniques such as fMRI are also used to study brain activity; these techniques have mainly been used with human subjects, because they require a conscious subject to remain motionless for long periods of time, but they have the great advantage of being noninvasive. + +Another approach to brain function is to examine the consequences of damage to specific brain areas. Even though it is protected by the skull and meninges, surrounded by cerebrospinal fluid, and isolated from the bloodstream by the blood–brain barrier, the delicate nature of the brain makes it vulnerable to numerous diseases and several types of damage. In humans, the effects of strokes and other types of brain damage have been a key source of information about brain function. Because there is no ability to experimentally control the nature of the damage, however, this information is often difficult to interpret. In animal studies, most commonly involving rats, it is possible to use electrodes or locally injected chemicals to produce precise patterns of damage and then examine the consequences for behavior. + +Computational neuroscience encompasses two approaches: first, the use of computers to study the brain; second, the study of how brains perform computation. On one hand, it is possible to write a computer program to simulate the operation of a group of neurons by making use of systems of equations that describe their electrochemical activity; such simulations are known as biologically realistic neural networks. On the other hand, it is possible to study algorithms for neural computation by simulating, or mathematically analyzing, the operations of simplified "units" that have some of the properties of neurons but abstract out much of their biological complexity. The computational functions of the brain are studied both by computer scientists and neuroscientists. + +Computational neurogenetic modeling is concerned with the study and development of dynamic neuronal models for modeling brain functions with respect to genes and dynamic interactions between genes. + +Recent years have seen increasing applications of genetic and genomic techniques to the study of the brain and a focus on the roles of neurotrophic factors and physical activity in neuroplasticity. The most common subjects are mice, because of the availability of technical tools. It is now possible with relative ease to "knock out" or mutate a wide variety of genes, and then examine the effects on brain function. More sophisticated approaches are also being used: for example, using Cre-Lox recombination it is possible to activate or deactivate genes in specific parts of the brain, at specific times. + +History + +The oldest brain to have been discovered was in Armenia in the Areni-1 cave complex. The brain, estimated to be over 5,000 years old, was found in the skull of a 12 to 14-year-old girl. Although the brains were shriveled, they were well preserved due to the climate found inside the cave. + +Early philosophers were divided as to whether the seat of the soul lies in the brain or heart. Aristotle favored the heart, and thought that the function of the brain was merely to cool the blood. Democritus, the inventor of the atomic theory of matter, argued for a three-part soul, with intellect in the head, emotion in the heart, and lust near the liver. The unknown author of On the Sacred Disease, a medical treatise in the Hippocratic Corpus, came down unequivocally in favor of the brain, writing: + +The Roman physician Galen also argued for the importance of the brain, and theorized in some depth about how it might work. Galen traced out the anatomical relationships among brain, nerves, and muscles, demonstrating that all muscles in the body are connected to the brain through a branching network of nerves. He postulated that nerves activate muscles mechanically by carrying a mysterious substance he called pneumata psychikon, usually translated as "animal spirits". Galen's ideas were widely known during the Middle Ages, but not much further progress came until the Renaissance, when detailed anatomical study resumed, combined with the theoretical speculations of René Descartes and those who followed him. Descartes, like Galen, thought of the nervous system in hydraulic terms. He believed that the highest cognitive functions are carried out by a non-physical res cogitans, but that the majority of behaviors of humans, and all behaviors of animals, could be explained mechanistically. + +The first real progress toward a modern understanding of nervous function, though, came from the investigations of Luigi Galvani (1737–1798), who discovered that a shock of static electricity applied to an exposed nerve of a dead frog could cause its leg to contract. Since that time, each major advance in understanding has followed more or less directly from the development of a new technique of investigation. Until the early years of the 20th century, the most important advances were derived from new methods for staining cells. Particularly critical was the invention of the Golgi stain, which (when correctly used) stains only a small fraction of neurons, but stains them in their entirety, including cell body, dendrites, and axon. Without such a stain, brain tissue under a microscope appears as an impenetrable tangle of protoplasmic fibers, in which it is impossible to determine any structure. In the hands of Camillo Golgi, and especially of the Spanish neuroanatomist Santiago Ramón y Cajal, the new stain revealed hundreds of distinct types of neurons, each with its own unique dendritic structure and pattern of connectivity. + +In the first half of the 20th century, advances in electronics enabled investigation of the electrical properties of nerve cells, culminating in work by Alan Hodgkin, Andrew Huxley, and others on the biophysics of the action potential, and the work of Bernard Katz and others on the electrochemistry of the synapse. These studies complemented the anatomical picture with a conception of the brain as a dynamic entity. Reflecting the new understanding, in 1942 Charles Sherrington visualized the workings of the brain waking from sleep: + +The invention of electronic computers in the 1940s, along with the development of mathematical information theory, led to a realization that brains can potentially be understood as information processing systems. This concept formed the basis of the field of cybernetics, and eventually gave rise to the field now known as computational neuroscience. The earliest attempts at cybernetics were somewhat crude in that they treated the brain as essentially a digital computer in disguise, as for example in John von Neumann's 1958 book, The Computer and the Brain. Over the years, though, accumulating information about the electrical responses of brain cells recorded from behaving animals has steadily moved theoretical concepts in the direction of increasing realism. + +One of the most influential early contributions was a 1959 paper titled What the frog's eye tells the frog's brain: the paper examined the visual responses of neurons in the retina and optic tectum of frogs, and came to the conclusion that some neurons in the tectum of the frog are wired to combine elementary responses in a way that makes them function as "bug perceivers". A few years later David Hubel and Torsten Wiesel discovered cells in the primary visual cortex of monkeys that become active when sharp edges move across specific points in the field of view—a discovery for which they won a Nobel Prize. Follow-up studies in higher-order visual areas found cells that detect binocular disparity, color, movement, and aspects of shape, with areas located at increasing distances from the primary visual cortex showing increasingly complex responses. Other investigations of brain areas unrelated to vision have revealed cells with a wide variety of response correlates, some related to memory, some to abstract types of cognition such as space. + +Theorists have worked to understand these response patterns by constructing mathematical models of neurons and neural networks, which can be simulated using computers. Some useful models are abstract, focusing on the conceptual structure of neural algorithms rather than the details of how they are implemented in the brain; other models attempt to incorporate data about the biophysical properties of real neurons. No model on any level is yet considered to be a fully valid description of brain function, though. The essential difficulty is that sophisticated computation by neural networks requires distributed processing in which hundreds or thousands of neurons work cooperatively—current methods of brain activity recording are only capable of isolating action potentials from a few dozen neurons at a time. + +Furthermore, even single neurons appear to be complex and capable of performing computations. So, brain models that do not reflect this are too abstract to be representative of brain operation; models that do try to capture this are very computationally expensive and arguably intractable with present computational resources. However, the Human Brain Project is trying to build a realistic, detailed computational model of the entire human brain. The wisdom of this approach has been publicly contested, with high-profile scientists on both sides of the argument. + +In the second half of the 20th century, developments in chemistry, electron microscopy, genetics, computer science, functional brain imaging, and other fields progressively opened new windows into brain structure and function. In the United States, the 1990s were officially designated as the "Decade of the Brain" to commemorate advances made in brain research, and to promote funding for such research. + +In the 21st century, these trends have continued, and several new approaches have come into prominence, including multielectrode recording, which allows the activity of many brain cells to be recorded all at the same time; genetic engineering, which allows molecular components of the brain to be altered experimentally; genomics, which allows variations in brain structure to be correlated with variations in DNA properties and neuroimaging. + +Society and culture + +As food + +Animal brains are used as food in numerous cuisines. + +In rituals +Some archaeological evidence suggests that the mourning rituals of European Neanderthals also involved the consumption of the brain. + +The Fore people of Papua New Guinea are known to eat human brains.

The Greek name Byzantion and its Latinization Byzantium continued to be used as a name of Constantinople sporadically and to varying degrees during the thousand year existence of the Byzantine Empire. Byzantium was colonized by Greeks from Megara in the 7th century BC and remained primarily Greek-speaking until its conquest by the Ottoman Empire in AD 1453. + +Etymology + +The etymology of Byzantium is unknown. It has been suggested that the name is of Thracian origin. It may be derived from the Thracian personal name Byzas which means "he-goat". Ancient Greek legend refers to the Greek king Byzas, the leader of the Megarian colonists and founder of the city. The name Lygos for the city, which likely corresponds to an earlier Thracian settlement, is mentioned by Pliny the Elder in his Natural History. + +Byzántios, plural Byzántioi (, ; adjective the same) referred to Byzantion's inhabitants, also used as an ethnonym for the people of the city and as a family name. In the Middle Ages, Byzántion was also a synecdoche for the eastern Roman Empire. (An ellipsis of ). Byzantinós (, ) denoted an inhabitant of the empire. The Anglicization of Latin Byzantinus yielded "Byzantine", with 15th and 16th century forms including Byzantin, Bizantin(e), Bezantin(e), and Bysantin as well as Byzantian and Bizantian. + +The name Byzantius and Byzantinus were applied from the 9th century to gold Byzantine coinage, reflected in the French besant (d'or), Italian bisante, and English besant, byzant, or bezant. The English usage, derived from Old French besan (pl. besanz), and relating to the coin, dates from the 12th century. + +Later, the name Byzantium became common in the West to refer to the Eastern Roman Empire, whose capital was Constantinople. As a term for the east Roman state as a whole, Byzantium was introduced by the historian Hieronymus Wolf only in 1555, a century after the last remnants of the empire, whose inhabitants continued to refer to their polity as the Roman Empire (), had ceased to exist. + +Other places were historically known as Byzántion (Βυζάντιον) – a city in Libya mentioned by Stephanus of Byzantium and another on the western coast of India referred to by the Periplus of the Erythraean Sea; in both cases the names were probably adaptations of names in local languages. Faustus of Byzantium was from a city of that name in Cilicia. + +History + +The origins of Byzantium are shrouded in legend. Tradition says that Byzas of Megara (a city-state near Athens) founded the city when he sailed northeast across the Aegean Sea. The date is usually given as 667 BC on the authority of Herodotus, who states the city was founded 17 years after Chalcedon. Eusebius, who wrote almost 800 years later, dates the founding of Chalcedon to 685/4 BC, but he also dates the founding of Byzantium to 656 BC (or a few years earlier depending on the edition). Herodotus' dating was later favored by Constantine the Great, who celebrated Byzantium's 1000th anniversary between the years 333 and 334. + +Byzantium was mainly a trading city due to its location at the Black Sea's only entrance. Byzantium later conquered Chalcedon, across the Bosphorus on the Asiatic side. + +The city was taken by the Persian Empire at the time of the Scythian campaign (513 BC) of King Darius I (r. 522–486 BC), and was added to the administrative province of Skudra. Though Achaemenid control of the city was never as stable as compared to other cities in Thrace, it was considered, alongside Sestos, to be one of the foremost Achaemenid ports on the European coast of the Bosphorus and the Hellespont. + +Byzantium was besieged by Greek forces during the Peloponnesian War. As part of Sparta's strategy for cutting off grain supplies to Athens during their siege of Athens, Sparta took control of the city in 411 BC, to bring the Athenians into submission. The Athenian military later retook the city in 408 BC, when the Spartans had withdrawn following their settlement. + +After siding with Pescennius Niger against the victorious Septimius Severus, the city was besieged by Roman forces and suffered extensive damage in AD 196. Byzantium was rebuilt by Septimius Severus, now emperor, and quickly regained its previous prosperity. It was bound to Perinthus during the period of Septimius Severus. The strategic and highly defensible (due to being surrounded by water on almost all sides) location of Byzantium attracted Roman Emperor Constantine I who, in AD 330, refounded it as an imperial residence inspired by Rome itself, known as Nova Roma. Later the city was called Constantinople (Greek Κωνσταντινούπολις, Konstantinoupolis, "city of Constantine"). + +This combination of imperialism and location would affect Constantinople's role as the nexus between the continents of Europe and Asia. It was a commercial, cultural, and diplomatic centre and for centuries formed the capital of the Byzantine Empire, which decorated the city with numerous monuments, some still standing today. With its strategic position, Constantinople controlled the major trade routes between Asia and Europe, as well as the passage from the Mediterranean Sea to the Black Sea. On May 29, 1453, the city was conquered by the Ottoman Turks, and again became the capital of a powerful state, the Ottoman Empire. The Turks called the city "Istanbul" (although it was not officially renamed until 1930); the name derives from the Greek phrase "στην πόλη", which means "to the city". To this day it remains the largest and most populous city in Turkey, although Ankara is now the national capital. + +Emblem + +By the late Hellenistic or early Roman period (1st century BC), the star and crescent motif was associated to some degree with Byzantium; even though it became more widely used as the royal emblem of Mithradates VI Eupator (who for a time incorporated the city into his empire). + +Some Byzantine coins of the 1st century BC and later show the head of Artemis with bow and quiver, and feature a crescent with what appears to be an eight-rayed star on the reverse. +According to accounts which vary in some of the details, in 340 BC the Byzantines and their allies the Athenians were under siege by the troops of Philip of Macedon. On a particularly dark and wet night Philip attempted a surprise attack but was thwarted by the appearance of a bright light in the sky. This light is occasionally described by subsequent interpreters as a meteor, sometimes as the moon, and some accounts also mention the barking of dogs. However, the original accounts mention only a bright light in the sky, without specifying the moon. To commemorate the event the Byzantines erected a statue of Hecate lampadephoros (light-bearer or bringer). This story survived in the works of Hesychius of Miletus, who in all probability lived in the time of Justinian I. His works survive only in fragments preserved in Photius and the tenth century lexicographer Suidas. The tale is also related by Stephanus of Byzantium, and Eustathius. + +Devotion to Hecate was especially favored by the Byzantines for her aid in having protected them from the incursions of Philip of Macedon. Her symbols were the crescent and star, and the walls of her city were her provenance. This contradicts claims that only the symbol of the crescent was meant to symbolize Hecate, whereas the star was only added later in order to symbolize the Virgin Mary, as Constantine I is said to have rededicated the city to her in the year 330. + +It is unclear precisely how the symbol Hecate/Artemis, one of many goddesses would have been transferred to the city itself, but it seems likely to have been an effect of being credited with the intervention against Philip and the subsequent honors. This was a common process in ancient Greece, as in Athens where the city was named after Athena in honor of such an intervention in time of war. + +Cities in the Roman Empire often continued to issue their own coinage. "Of the many themes that were used on local coinage, celestial and astral symbols often appeared, mostly stars or crescent moons." The wide variety of these issues, and the varying explanations for the significance of the star and crescent on Roman coinage precludes their discussion here. It is, however, apparent that by the time of the Romans, coins featuring a star or crescent in some combination were not at all rare. + +People +Homerus, tragedian, lived in the early 3rd century BC +Philo, engineer, lived +Epigenes of Byzantium, astrologer, lived in the 3rd–2nd century BC +Aristophanes of Byzantium, a scholar who flourished in Alexandria, 3rd–2nd century BC +Myro, a Hellenistic female poet + +See also + Sarayburnu, which is the geographic location of ancient Byzantium + Timeline of Istanbul history + +Notes + +References + +Sources + + + Harris, Jonathan, Constantinople: Capital of Byzantium (Hambledon/Continuum, London, 2007). +Jeffreys, Elizabeth and Michael, and Moffatt, Ann, Byzantine Papers: Proceedings of the First Australian Byzantine Studies Conference, Canberra, 17–19 May 1978 (Australian National University, Canberra, 1979). + Istanbul Historical Information – Istanbul Informative Guide To The City.

Construction of the Berlin Wall was commenced by the government of the GDR on 13 August 1961. It included guard towers placed along large concrete walls, accompanied by a wide area (later known as the "death strip") that contained anti-vehicle trenches, beds of nails and other defenses. The primary intention for the Wall's construction was to prevent East German citizens from fleeing to the West. + +The Soviet Bloc propaganda portrayed the Wall as protecting its population from "fascist elements conspiring to prevent the will of the people" from building a communist state in the GDR. The authorities officially referred to the Berlin Wall as the Anti-Fascist Protection Rampart (, ). The West Berlin city government sometimes referred to it as the "Wall of Shame", a term coined by mayor Willy Brandt in reference to the Wall's restriction on freedom of movement. Along with the separate and much longer inner German border, which demarcated the border between East and West Germany, it came to symbolize physically the Iron Curtain that separated the Western Bloc and Soviet satellite states of the Eastern Bloc during the Cold War. + +Before the Wall's erection, 3.5 million East Germans circumvented Eastern Bloc emigration restrictions and defected from the GDR, many by crossing over the border from East Berlin into West Berlin; from there they could then travel to West Germany and to other Western European countries. Between 1961 and 1989, the Wall prevented almost all such emigration. During this period, over 100,000 people attempted to escape, and over 5,000 people succeeded in escaping over the Wall, with an estimated death toll of those murdered by East German authorities ranging from 136 to more than 200 in and around Berlin. + +In 1989, a series of revolutions in nearby Eastern Bloc countries—in Poland and Hungary in particular—caused a chain reaction in East Germany. In particular, the Pan-European Picnic in August 1989 set in motion a peaceful development during which the Iron Curtain largely broke, the rulers in the East came under pressure to cease their repressive policies, the Berlin Wall fell and finally the Eastern Bloc collapsed. After several weeks of civil unrest, the East German government announced on 9 November 1989 that all GDR citizens could visit the FRG and West Berlin. Crowds of East Germans crossed and climbed onto the Wall, joined by West Germans on the other side in a celebratory atmosphere. Over the next few weeks, souvenir hunters chipped away parts of the Wall. The Brandenburg Gate, a few meters from the Berlin Wall, was opened on 22 December 1989. The demolition of the Wall officially began on 13 June 1990 and was completed in 1994. The fall of the Berlin Wall paved the way for German reunification, which formally took place on 3 October 1990. + +Background + +Post-war Germany +After the end of World War II in Europe, what remained of pre-war Germany west of the Oder-Neisse line was divided into four occupation zones (as per the Potsdam Agreement), each one controlled by one of the four occupying Allied powers: the United States, the United Kingdom, France and the Soviet Union. The capital of Berlin, as the seat of the Allied Control Council, was similarly subdivided into four sectors despite the city's location, which was fully within the Soviet zone. + +Within two years, political divisions increased between the Soviets and the other occupying powers. These included the Soviets' refusal to agree to reconstruction plans making post-war Germany self-sufficient, and to a detailed accounting of industrial plants, goods and infrastructure—some of which had already been removed by the Soviets. France, the United Kingdom, the United States, and the Benelux countries later met to combine the non-Soviet zones of Germany into one zone for reconstruction, and to approve the extension of the Marshall Plan. + +Eastern Bloc and the Berlin airlift + +Following the defeat of Nazi Germany in World War II, the Soviet Union engineered the installation of communist regimes in most of the countries occupied by Soviet military forces at the end of the War, including Poland, Hungary, Czechoslovakia, Bulgaria, Romania, and the GDR, which together with Albania formed the Comecon in 1949 and later a military alliance, the Warsaw Pact. The beginning of the Cold War saw the Eastern Bloc of the Soviet Union confront the Western Bloc of the United States, with the latter grouping becoming largely united in 1949 under NATO and the former grouping becoming largely united in 1955 under the Warsaw Pact. As the Soviet Union already had an armed presence and political domination all over its eastern satellite states by 1955, the pact has been long considered "superfluous", and because of the rushed way in which it was conceived, NATO officials labeled it a "cardboard castle". There was no direct military confrontation between the two organizations; instead, the conflict was fought on an ideological basis and through proxy wars. Both NATO and the Warsaw Pact led to the expansion of military forces and their integration into the respective blocs. The Warsaw Pact's largest military engagement was the Warsaw Pact invasion of Czechoslovakia, its own member state, in August 1968. + +Since the end of the War, the USSR installed a Soviet-style regime in the Soviet occupation zone of Germany and later founded the GDR, with the country's political system based on a centrally planned socialist economic model with nationalized means of production, and with repressive secret police institutions, under party dictatorship of the SED (Sozialistische Einheitspartei Deutschlands; Socialist Unity Party of Germany) similar to the party dictatorship of the Soviet Communist Party in the USSR. + +At the same time, a parallel country was established under the control of the Western powers in the zones of post-war Germany occupied by them, culminating in the foundation of the Federal Republic of Germany in 1949, which initially claimed to be the sole legitimate power in all of Germany, East and West. The material standard of living in the Western zones of Berlin began to improve quickly, and residents of the Soviet zone soon began leaving for the West in large numbers, fleeing hunger, poverty and repression in the Soviet Zone for a better life in the West. Soon residents of other parts of the Soviet zone began to escape to the West through Berlin, and this migration, called in Germany "Republikflucht", deprived the Soviet zone not only of working forces desperately needed for post-war reconstruction but disproportionately highly educated people, which came to be known as the "Brain Drain". + +In 1948, in response to moves by the Western powers to establish a separate, federal system of government in the Western zones, and to extend the US Marshall Plan of economic assistance to Germany, the Soviets instituted the Berlin Blockade, preventing people, food, materials and supplies from arriving in West Berlin by land routes through the Soviet zone. The United States, the United Kingdom, France, Canada, Australia, New Zealand and several other countries began a massive "airlift", supplying West Berlin with food and other supplies. The Soviets mounted a public relations campaign against the Western policy change. Communists attempted to disrupt the elections of 1948, preceding large losses therein, while 300,000 Berliners demonstrated for the international airlift to continue. In May 1949, Stalin lifted the blockade, permitting the resumption of Western shipments to Berlin. + +The German Democratic Republic (the "GDR"; East Germany) was declared on 7 October 1949. On that day, the USSR ended the Soviet military government which had governed the Soviet Occupation Zone (Sowetische Besatzungszone) since the end of the War and handed over legal power to the Provisorische Volkskammer under the new Constitution of the GDR which came into force that day. However, until 1955, the Soviets maintained considerable legal control over the GDR state, including the regional governments, through the Sowetische Kontrollkommission and maintained a presence in various East German administrative, military, and secret police structures. Even after legal sovereignty of the GDR was restored in 1955, the Soviet Union continued to maintain considerable influence over administration and lawmaking in the GDR through the Soviet embassy and through the implicit threat of force which could be exercised through the continuing large Soviet military presence in the GDR, which was used to repress protests in East Germany bloodily in June 1953. + +East Germany differed from West Germany (Federal Republic of Germany), which developed into a Western capitalist country with a social market economy and a democratic parliamentary government. Continual economic growth starting in the 1950s fueled a 20-year "economic miracle" (). As West Germany's economy grew, and its standard of living steadily improved, many East Germans wanted to move to West Germany. + +Emigration westward in the early 1950s + +After the Soviet occupation of Eastern Europe at the end of World War II, the majority of those living in the newly acquired areas of the Eastern Bloc aspired to independence and wanted the Soviets to leave. Taking advantage of the zonal border between occupied zones in Germany, the number of GDR citizens moving to West Germany totaled 187,000 in 1950; 165,000 in 1951; 182,000 in 1952; and 331,000 in 1953. One reason for the sharp 1953 increase was fear of potential further Sovietization, given the increasingly paranoid actions of Joseph Stalin in late 1952 and early 1953. In the first six months of 1953, 226,000 had fled. + +Erection of the inner German border + +By the early 1950s, the Soviet approach to controlling national movement, restricting emigration, was emulated by most of the rest of the Eastern Bloc, including East Germany. The restrictions presented a quandary for some Eastern Bloc states, which had been more economically advanced and open than the Soviet Union, such that crossing borders seemed more natural—especially where no prior border existed between East and West Germany. + +Up until 1952, the demarcation lines between East Germany and the western occupied zones could be easily crossed in most places. On 1 April 1952, East German leaders met the Soviet leader Joseph Stalin in Moscow; during the discussions, Stalin's foreign minister Vyacheslav Molotov proposed that the East Germans should "introduce a system of passes for visits of West Berlin residents to the territory of East Berlin [so as to stop] free movement of Western agents" in the GDR. Stalin agreed, calling the situation "intolerable". He advised the East Germans to build up their border defenses, telling them that "The demarcation line between East and West Germany should be considered a border—and not just any border, but a dangerous one ... The Germans will guard the line of defence with their lives." + +Consequently, the inner German border between the two German states was closed, and a barbed-wire fence erected. The border between the Western and Eastern sectors of Berlin, however, remained open, although traffic between the Soviet and the Western sectors was somewhat restricted. This resulted in Berlin becoming a magnet for East Germans desperate to escape life in the GDR, and also a flashpoint for tension between the United States and the Soviet Union. + +In 1955, the Soviets gave East Germany authority over civilian movement in Berlin, passing control to a regime not recognized in the West. Initially, East Germany granted "visits" to allow its residents access to West Germany. However, following the defection of large numbers of East Germans (known as Republikflucht) under this regime, the new East German state legally restricted virtually all travel to the West in 1956. Soviet East German ambassador Mikhail Pervukhin observed that "the presence in Berlin of an open and essentially uncontrolled border between the socialist and capitalist worlds unwittingly prompts the population to make a comparison between both parts of the city, which unfortunately does not always turn out in favour of Democratic [East] Berlin." + +Berlin emigration loophole +With the closing of the inner German border officially in 1952, the border in Berlin remained considerably more accessible because it was administered by all four occupying powers. Accordingly, Berlin became the main route by which East Germans left for the West. On 11 December 1957, East Germany introduced a new passport law that reduced the overall number of refugees leaving Eastern Germany. + +It had the unintended result of drastically increasing the percentage of those leaving through West Berlin from 60% to well over 90% by the end of 1958. Those caught trying to leave East Berlin were subjected to heavy penalties, but with no physical barrier and subway train access still available to West Berlin, such measures were ineffective. The Berlin sector border was essentially a "loophole" through which Eastern Bloc citizens could still escape. The 3.5 million East Germans who had left by 1961 totalled approximately 20% of the entire East German population. + +An important reason that passage between East Germany and West Berlin was not stopped earlier was that doing so would cut off much of the railway traffic in East Germany. Construction of a new railway bypassing West Berlin, the Berlin outer ring, commenced in 1951. Following the completion of the railway in 1961, closing the border became a more practical proposition. + +Brain drain +The emigrants tended to be young and well-educated, leading to the "brain drain" feared by officials in East Germany. Yuri Andropov, then the CPSU Director on Relations with Communist and Workers' Parties of Socialist Countries, wrote an urgent letter on 28 August 1958 to the Central Committee about the significant 50% increase in the number of East German intelligentsia among the refugees. Andropov reported that, while the East German leadership stated that they were leaving for economic reasons, testimony from refugees indicated that the reasons were more political than material. He stated "the flight of the intelligentsia has reached a particularly critical phase." + +By 1960, the combination of World War II and the massive emigration westward left East Germany with only 61% of its population of working age, compared to 70.5% before the war. The loss was disproportionately heavy among professionals: engineers, technicians, physicians, teachers, lawyers, and skilled workers. The direct cost of manpower losses to East Germany (and corresponding gain to the West) has been estimated at $7 billion to $9 billion, with East German party leader Walter Ulbricht later claiming that West Germany owed him $17 billion in compensation, including reparations as well as manpower losses. In addition, the drain of East Germany's young population potentially cost it over 22.5 billion marks in lost educational investment. The brain drain of professionals had become so damaging to the political credibility and economic viability of East Germany that the re-securing of the German communist frontier was imperative. + +The exodus of emigrants from East Germany presented two minor potential benefits: an easy way to smuggle East German secret agents to West Germany, and a reduction in the number of citizens hostile to the communist regime. Neither of these advantages, however, proved particularly useful. + +Start of the construction (1961) + +On 15 June 1961, First Secretary of the Socialist Unity Party and GDR State Council chairman Walter Ulbricht stated in an international press conference, (No one has the intention of erecting a wall!). It was the first time the colloquial term (wall) had been used in this context. + +The transcript of a telephone call between Nikita Khrushchev and Ulbricht, on 1 August in the same year, suggests that the initiative for the construction of the Wall came from Khrushchev. However, other sources suggest that Khrushchev had initially been wary about building a wall, fearing negative Western reaction. Nevertheless, Ulbricht had pushed for a border closure for some time, arguing that East Germany's existence was at stake. + +Khrushchev had become emboldened upon seeing US president John F. Kennedy's youth and inexperience, which he considered a weakness. In the 1961 Vienna summit, Kennedy made the error of admitting that the US wouldn't actively oppose the building of a barrier. A feeling of miscalculation and failure immediately afterwards was admitted by Kennedy in a candid interview with New York Times columnist James "Scotty" Reston. On Saturday, 12 August 1961, the leaders of the GDR attended a garden party at a government guesthouse in , in a wooded area to the north of East Berlin. There, Ulbricht signed the order to close the border and erect a wall. + +At midnight, the police and units of the East German army began to close the border and, by Sunday morning, 13 August, the border with West Berlin was closed. East German troops and workers had begun to tear up streets running alongside the border to make them impassable to most vehicles and to install barbed wire entanglements and fences along the around the three western sectors, and the that divided West and East Berlin. The date of 13 August became commonly referred to as Barbed Wire Sunday in Germany. + +The barrier was built inside East Berlin on East German territory to ensure that it did not encroach on West Berlin at any point. Generally, the Wall was only slightly inside East Berlin, but in a few places it was some distance from the legal border, most notably at Potsdamer Bahnhof and the Lenné Triangle that is now much of the Potsdamer Platz development. + +Later, the initial barrier was built up into the Wall proper, the first concrete elements and large blocks being put in place on 17 August. During the construction of the Wall, National People's Army (NVA) and Combat Groups of the Working Class (KdA) soldiers stood in front of it with orders to shoot anyone who attempted to defect. Additionally, chain fences, walls, minefields and other obstacles were installed along the length of East Germany's western border with West Germany proper. A wide no man's land was cleared as well to provide a better overview and a clear line of fire at fleeing refugees. + +Immediate effects +With the closing of the east–west sector boundary in Berlin, the vast majority of East Germans could no longer travel or emigrate to West Germany. Berlin soon went from being the easiest place to make an unauthorized crossing between East and West Germany to being the most difficult. Many families were split, while East Berliners employed in the West were cut off from their jobs. West Berlin became an isolated exclave in a hostile land. West Berliners demonstrated against the Wall, led by their Mayor () Willy Brandt, who criticized the United States for failing to respond and went so far as to suggest to Washington what to do next. Kennedy was furious. Allied intelligence agencies had hypothesized about a wall to stop the flood of refugees, but the main candidate for its location was around the perimeter of the city. In 1961, Secretary of State Dean Rusk proclaimed, "The Wall certainly ought not to be a permanent feature of the European landscape. I see no reason why the Soviet Union should think it is—it is to their advantage in any way to leave there that monument to communist failure." + +United States and UK sources had expected the Soviet sector to be sealed off from West Berlin but were surprised by how long the East Germans took for such a move. They considered the Wall as an end to concerns about a GDR/Soviet retaking or capture of the whole of Berlin; the Wall would presumably have been an unnecessary project if such plans were afloat. Thus, they concluded that the possibility of a Soviet military conflict over Berlin had decreased. + +The East German government claimed that the Wall was an "anti-fascist protective rampart" () intended to dissuade aggression from the West. Another official justification was the activities of Western agents in Eastern Europe. The Eastern German government also claimed that West Berliners were buying out state-subsidized goods in East Berlin. East Germans and others greeted such statements with skepticism, as most of the time, the border was only closed for citizens of East Germany traveling to the West, but not for residents of West Berlin travelling to the East. The construction of the Wall had caused considerable hardship to families divided by it. Most people believed that the Wall was mainly a means of preventing the citizens of East Germany from entering or fleeing to West Berlin. + +Secondary response + +The National Security Agency was the only American intelligence agency that was aware that East Germany was to take action to deal with the brain drain problem. On 9 August 1961, the NSA intercepted an advance warning information of the Socialist Unity Party's plan to close the intra-Berlin border between East and West Berlin completely for foot traffic. The interagency intelligence Berlin Watch Committee assessed that this intercept "might be the first step in a plan to close the border." This warning did not reach John F. Kennedy until noon on 13 August 1961, while he was vacationing in his yacht off the Kennedy Compound in Hyannis Port, Massachusetts. While Kennedy was angry that he had no advance warning, he was relieved that the East Germans and the Soviets had only divided Berlin without taking any action against West Berlin's access to the West. However, he denounced the Berlin Wall, whose erection worsened the relations between the United States and the Soviet Union. + +In response to the erection of the Berlin Wall, a retired general, Lucius D. Clay, was appointed by Kennedy as his special advisor with ambassadorial rank. Clay had been the Military Governor of the US Zone of Occupation in Germany during the period of the Berlin Blockade and had ordered the first measures in what became the Berlin Airlift. He was immensely popular with the residents of West Berlin, and his appointment was an unambiguous sign that Kennedy would not compromise on the status of West Berlin. As a symbolic gesture, Kennedy sent Clay and Vice President Lyndon B. Johnson to West Berlin. They landed at Tempelhof Airport on the afternoon of Saturday, 19 August 1961 and were greeted enthusiastically by the local population. + +They arrived in a city defended by three Allied brigades—one each from the UK (Berlin Infantry Brigade), the US (Berlin Brigade), and France (Forces Françaises à Berlin). On 16 August, Kennedy had given the order for them to be reinforced. Early on 19 August, the 1st Battle Group, 18th Infantry Regiment (commanded by Colonel Glover S. Johns Jr.) was alerted. + +On Sunday morning, U.S. troops marched from West Germany through East Germany, bound for West Berlin. Lead elements—arranged in a column of 491 vehicles and trailers carrying 1,500 men, divided into five march units—left the Helmstedt-Marienborn checkpoint at 06:34. At Marienborn, the Soviet checkpoint next to Helmstedt on the West German-East German border, US personnel were counted by guards. The column was long, and covered from Marienborn to Berlin in full battle gear. East German police watched from beside trees next to the autobahn all the way along. + +The front of the convoy arrived at the outskirts of Berlin just before noon, to be met by Clay and Johnson, before parading through the streets of Berlin in front of a large crowd. At 04:00 on 21 August, Lyndon Johnson left West Berlin in the hands of General Frederick O. Hartel and his brigade of 4,224 officers and men. "For the next three and a half years, American battalions would rotate into West Berlin, by autobahn, at three-month intervals to demonstrate Allied rights to the city". + +The creation of the Wall had important implications for both German states. By stemming the exodus of people from East Germany, the East German government was able to reassert its control over the country: in spite of discontent with the Wall, economic problems caused by dual currency and the black market were largely eliminated. The economy in the GDR began to grow. However, the Wall proved a public relations disaster for the communist bloc as a whole. Western powers portrayed it as a symbol of communist tyranny, particularly after East German border guards shot and killed would-be defectors. Such fatalities were later treated as acts of murder by the reunified Germany. + +Structure and adjacent areas + +Layout and modifications + +The Berlin Wall was more than long. In June 1962, a second, parallel fence, also known as a "hinterland" wall (inner wall), was built some farther into East German territory. The houses contained between the wall and fences were razed and the inhabitants relocated, thus establishing what later became known as the death strip. The death strip was covered with raked sand or gravel, rendering footprints easy to notice, easing the detection of trespassers and also enabling officers to see which guards had neglected their task; it offered no cover; and, most importantly, it offered clear fields of fire for the Wall guards. + +Through the years, the Berlin Wall evolved through four versions: +Wire fence and concrete block wall (1961) +Improved wire fence (1962–1965) +Improved concrete wall (1965–1975) + (Border Wall 75) (1975–1989) + +The "fourth-generation Wall", known officially as "" (retaining wall element UL 12.11), was the final and most sophisticated version of the Wall. Begun in 1975 and completed about 1980, it was constructed from 45,000 separate sections of reinforced concrete, each high and wide, and cost DDM16,155,000 or about US$3,638,000. The concrete provisions added to this version of the Wall were done to prevent escapees from driving their cars through the barricades. At strategic points, the Wall was constructed to a somewhat weaker standard, so that East German and Soviet armored vehicles could easily break through in the event of war. + +The top of the wall was lined with a smooth pipe, intended to make it more difficult to scale. The Wall was reinforced by mesh fencing, signal fencing, anti-vehicle trenches, barbed wire, dogs on long lines, "beds of nails" (also known as "Stalin's Carpet") under balconies hanging over the "death strip", over 116 watchtowers, and 20 bunkers with hundreds of guards. This version of the Wall is the one most commonly seen in photographs, and surviving fragments of the Wall in Berlin and elsewhere around the world are generally pieces of the fourth-generation Wall. The layout came to resemble the inner German border in most technical aspects, except that the Berlin Wall had no landmines nor spring-guns. Maintenance was performed on the outside of the wall by personnel who accessed the area outside it either via ladders or via hidden doors within the wall. These doors could not be opened by a single person, needing two separate keys in two separate keyholes to unlock. + +As was the case with the inner German border, an unfortified strip of Eastern territory was left outside the wall. This outer strip was used by workers to paint over graffiti and perform other maintenance on the outside of the wall Unlike the inner German border, however, the outer strip was usually no more than four meters wide, and, in photos from the era, the exact location of the actual border in many places appears not even to have been marked. Also in contrast with the inner German border, little interest was shown by East German law enforcement in keeping outsiders off the outer strip; sidewalks of West Berlin streets even ran inside it. + +Despite the East German government's general policy of benign neglect, vandals were known to have been pursued in the outer strip, and even arrested. In 1986, defector and political activist Wolfram Hasch and four other defectors were standing inside the outer strip defacing the wall when East German personnel emerged from one of the hidden doors to apprehend them. All but Hasch escaped back into the western sector. Hasch himself was arrested, dragged through the door into the death strip, and later convicted of illegally crossing the de jure border outside the wall. Graffiti artist Thierry Noir has reported having often been pursued there by East German soldiers. While some graffiti artists were chased off the outer strip, others, such as Keith Haring, were seemingly tolerated. + +Surrounding municipalities +Besides the sector-sector boundary within Berlin itself, the Wall also separated West Berlin from the present-day state of Brandenburg. The following present-day municipalities, listed in counter-clockwise direction, share a border with the former West Berlin: +Oberhavel: Mühlenbecker Land (partially), Glienicke/Nordbahn, Hohen Neuendorf, Hennigsdorf +Havelland: Schönwalde-Glien, Falkensee, Dallgow-Döberitz +Potsdam (urban district) +Potsdam-Mittelmark: Stahnsdorf, Kleinmachnow, Teltow +Teltow-Fläming: Großbeeren, Blankenfelde-Mahlow +Dahme-Spreewald: Schönefeld (partially) + +Official crossings and usage + +There were nine border crossings between East and West Berlin. These allowed visits by West Berliners, other West Germans, Western foreigners and Allied personnel into East Berlin, as well as visits by GDR citizens and citizens of other socialist countries into West Berlin, provided that they held the necessary permits. These crossings were restricted according to which nationality was allowed to use it (East Germans, West Germans, West Berliners, other countries). The best known was the vehicle and pedestrian checkpoint at the corner of Friedrichstraße and Zimmerstraße (Checkpoint Charlie), which was restricted to Allied personnel and foreigners. + +Several other border crossings existed between West Berlin and surrounding East Germany. These could be used for transit between West Germany and West Berlin, for visits by West Berliners into East Germany, for transit into countries neighbouring East Germany (Poland, Czechoslovakia, Denmark), and for visits by East Germans into West Berlin carrying a permit. After the 1972 agreements, new crossings were opened to allow West Berlin waste to be transported into East German dumps, as well as some crossings for access to West Berlin's exclaves (see Steinstücken). + +Four autobahns connected West Berlin to West Germany, including Berlin-Helmstedt autobahn, which entered East German territory between the towns of Helmstedt and Marienborn (Checkpoint Alpha), and which entered West Berlin at Dreilinden (Checkpoint Bravo for the Allied forces) in southwestern Berlin. Access to West Berlin was also possible by railway (four routes) and by boat for commercial shipping via canals and rivers. + +Non-German Westerners could cross the border at Friedrichstraße station in East Berlin and at Checkpoint Charlie. When the Wall was erected, Berlin's complex public transit networks, the S-Bahn and U-Bahn, were divided with it. Some lines were cut in half; many stations were shut down. Three western lines traveled through brief sections of East Berlin territory, passing through eastern stations (called , or ghost stations) without stopping. Both the eastern and western networks converged at , which became a major crossing point for those (mostly Westerners) with permission to cross. + +Crossing + +West Germans and citizens of other Western countries could generally visit East Germany, often after applying for a visa at an East German embassy several weeks in advance. Visas for day trips restricted to East Berlin were issued without previous application in a simplified procedure at the border crossing. However, East German authorities could refuse entry permits without stating a reason. In the 1980s, visitors from the western part of the city who wanted to visit the eastern part had to exchange at least DM 25 into East German currency at the poor exchange rate of 1:1. It was forbidden to export East German currency from the East, but money not spent could be left at the border for possible future visits. Tourists crossing from the west had to also pay for a visa, which cost DM 5; West Berliners did not have to pay this fee. + +West Berliners initially could not visit East Berlin or East Germany at all—all crossing points were closed to them between 26 August 1961 and 17 December 1963. In 1963, negotiations between East and West resulted in a limited possibility for visits during the Christmas season that year (). Similar, very limited arrangements were made in 1964, 1965 and 1966. + +In 1971, with the Four Power Agreement on Berlin, agreements were reached that allowed West Berliners to apply for visas to enter East Berlin and East Germany regularly, comparable to the regulations already in force for West Germans. However, East German authorities could still refuse entry permits. + +East Berliners and East Germans could not, at first, travel to West Berlin or West Germany at all. This regulation remained in force essentially until the fall of the Wall, but over the years several exceptions to these rules were introduced, the most significant being: +Elderly pensioners could travel to the West starting in 1964 +Visits of relatives for important family matters +People who had to travel to the West for professional reasons (for example, artists, truck drivers, musicians, writers, etc.) + +For each of these exceptions, GDR citizens had to apply for individual approval, which was never guaranteed. In addition, even if travel was approved, GDR travellers could exchange only a very small amount of East German Marks into Deutsche Marks (DM), thus limiting the financial resources available for them to travel to the West. This led to the West German practice of granting a small amount of DM annually (Begrüßungsgeld, or welcome money) to GDR citizens visiting West Germany and West Berlin to help alleviate this situation. + +Citizens of other East European countries were in general subject to the same prohibition of visiting Western countries as East Germans, though the applicable exception (if any) varied from country to country. + +Allied military personnel and civilian officials of the Allied forces could enter and exit East Berlin without submitting to East German passport controls, purchasing a visa or being required to exchange money. Likewise, Soviet military patrols could enter and exit West Berlin. This was a requirement of the post-war Four Powers Agreements. A particular area of concern for the Western Allies involved official dealings with East German authorities when crossing the border, since Allied policy did not recognize the authority of the GDR to regulate Allied military traffic to and from West Berlin, as well as the Allied presence within Greater Berlin, including entry into, exit from, and presence within East Berlin. + +The Allies held that only the Soviet Union, and not the GDR, had the authority to regulate Allied personnel in such cases. For this reason, elaborate procedures were established to prevent inadvertent recognition of East German authority when engaged in travel through the GDR and when in East Berlin. Special rules applied to travel by Western Allied military personnel assigned to the military liaison missions accredited to the commander of Soviet forces in East Germany, located in Potsdam. + +Allied personnel were restricted by policy when travelling by land to the following routes: + +Transit between West Germany and West Berlin +Road: the Helmstedt–Berlin autobahn (A2) (checkpoints Alpha and Bravo respectively). Soviet military personnel manned these checkpoints and processed Allied personnel for travel between the two points. +Rail: Western Allied military personnel and civilian officials of the Allied forces were forbidden to use commercial train service between West Germany and West Berlin, because of GDR passport and customs controls when using them. Instead, the Allied forces operated a series of official (duty) trains that traveled between their respective duty stations in West Germany and West Berlin. When transiting the GDR, the trains would follow the route between Helmstedt and Griebnitzsee, just outside West Berlin. In addition to persons traveling on official business, authorized personnel could also use the duty trains for personal travel on a space-available basis. The trains traveled only at night, and as with transit by car, Soviet military personnel handled the processing of duty train travelers. (See History of the Berlin S-Bahn.) + +Entry into and exit from East Berlin +Checkpoint Charlie (as a pedestrian or riding in a vehicle) + +As with military personnel, special procedures applied to travel by diplomatic personnel of the Western Allies accredited to their respective embassies in the GDR. This was intended to prevent inadvertent recognition of East German authority when crossing between East and West Berlin, which could jeopardize the overall Allied position governing the freedom of movement by Allied forces personnel within all Berlin. + +Ordinary citizens of the Western Allied powers, not formally affiliated with the Allied forces, were authorized to use all designated transit routes through East Germany to and from West Berlin. Regarding travel to East Berlin, such persons could also use the Friedrichstraße train station to enter and exit the city, in addition to Checkpoint Charlie. In these instances, such travelers, unlike Allied personnel, had to submit to East German border controls. + +Defection attempts + +During the years of the Wall, around 5,000 people successfully defected to West Berlin. The number of people who died trying to cross the Wall, or as a result of the Wall's existence, has been disputed. The most vocal claims by Alexandra Hildebrandt, director of the Checkpoint Charlie Museum and widow of the museum's founder, estimated the death toll to be well above 200. A historic research group at the Centre for Contemporary History (ZZF) in Potsdam has confirmed at least 140 deaths. Prior official figures listed 98 as being killed. + +The East German government issued shooting orders (Schießbefehl) to border guards dealing with defectors, though such orders are not the same as "shoot to kill" orders. GDR officials denied issuing the latter. In an October 1973 order later discovered by researchers, guards were instructed that people attempting to cross the Wall were criminals and needed to be shot: + +Early successful escapes involved people jumping the initial barbed wire or leaping out of apartment windows along the line, but these ended as the Wall was fortified. East German authorities no longer permitted apartments near the Wall to be occupied, and any building near the Wall had its windows boarded and later bricked up. On 15 August 1961, Conrad Schumann was the first East German border guard to escape by jumping the barbed wire to West Berlin. + +On 22 August 1961, Ida Siekmann was the first casualty at the Berlin Wall: she died after she jumped out of her third floor apartment at 48 Bernauer Strasse. The first person to be shot and killed while trying to cross to West Berlin was Günter Litfin, a twenty-four-year-old tailor. He attempted to swim across the Spree to West Berlin on 24 August 1961, the same day that East German police had received shoot-to-kill orders to prevent anyone from escaping. + +Another dramatic escape was carried out in April 1963 by Wolfgang Engels, a 19-year-old civilian employee of the Nationale Volksarmee (NVA). Engels stole a Soviet armored personnel carrier from a base where he was deployed and drove it right into the Wall. He was fired at and seriously wounded by border guards. But a West German policeman intervened, firing his weapon at the East German border guards. The policeman removed Engels from the vehicle, which had become entangled in the barbed wire. + +East Germans successfully defected by a variety of methods: digging long tunnels under the Wall, waiting for favorable winds and taking a hot air balloon, sliding along aerial wires, flying ultralights and, in one instance, simply driving a sports car at full speed through the basic, initial fortifications. When a metal beam was placed at checkpoints to prevent this kind of defection, up to four people (two in the front seats and possibly two in the boot) drove under the bar in a sports car that had been modified to allow the roof and windscreen to come away when it made contact with the beam. They lay flat and kept driving forward. The East Germans then built zig-zagging roads at checkpoints. The sewer system predated the Wall, and some people escaped through the sewers, in a number of cases with assistance from the Unternehmen Reisebüro. In September 1962, 29 people escaped through a tunnel to the west. At least 70 tunnels were dug under the wall; only 19 were successful in allowing fugitives—about 400 persons—to escape. The East Germany authorities eventually used seismographic and acoustic equipment to detect the practice. In 1962, they planned an attempt to use explosives to destroy one tunnel, but this was not carried out as it was apparently sabotaged by a member of the Stasi. + +An airborne escape was made by Thomas Krüger, who landed a Zlin Z 42M light aircraft of the Gesellschaft für Sport und Technik, an East German youth military training organization, at RAF Gatow. His aircraft, registration DDR-WOH, was dismantled and returned to the East Germans by road, complete with humorous slogans painted on it by airmen of the Royal Air Force, such as "Wish you were here" and "Come back soon". + +If an escapee was wounded in a crossing attempt and lay on the death strip, no matter how close they were to the Western wall, Westerners could not intervene for fear of triggering engaging fire from the 'Grepos', the East Berlin border guards. The guards often let fugitives bleed to death in the middle of this ground, as in the most notorious failed attempt, that of Peter Fechter (aged 18) at a point near Zimmerstrasse in East Berlin. He was shot and bled to death, in full view of the Western media, on 17 August 1962. Fechter's death created negative publicity worldwide that led the leaders of East Berlin to place more restrictions on shooting in public places and provide medical care for possible "would-be escapers". The last person to be shot and killed while trying to cross the border was Chris Gueffroy on 6 February 1989, while the final person to die in an escape attempt was Winfried Freudenberg who was killed when his homemade natural gas-filled balloon crashed on 8 March 1989. + +The Wall gave rise to a widespread sense of desperation and oppression in East Berlin, as expressed in the private thoughts of one resident, who confided to her diary "Our lives have lost their spirit… we can do nothing to stop them." + +Concerts by Western artists and growing anti-Wall sentiment + +David Bowie, 1987 +On 6 June 1987, David Bowie, who earlier for several years lived and recorded in West Berlin, played a concert close to the Wall. This was attended by thousands of Eastern concertgoers across the Wall, followed by violent rioting in East Berlin. According to Tobias Ruther, these protests in East Berlin were the first in the sequence of riots that led to those of November 1989. Although other factors were probably more influential in the fall of the Wall, upon his death in 2016, the German Foreign Office tweeted "Good-bye, David Bowie. You are now among #Heroes. Thank you for helping to bring down the #wall." + +Bruce Springsteen, 1988 +On 19 July 1988, 16 months before the Wall came down, Bruce Springsteen and the E-Street Band, played Rocking the Wall, a live concert in East Berlin, which was attended by 300,000 in person and broadcast on television. Springsteen spoke to the crowd in German, saying: "I'm not here for or against any government. I've come to play rock 'n' roll for you in the hope that one day all the barriers will be torn down". East Germany and its FDJ youth organization were worried they were losing an entire generation. They hoped that by letting Springsteen in, they could improve their sentiment among East Germans. However, this strategy of "one step backwards, two steps forwards" backfired, and the concert only made East Germans hungrier for more of the freedoms that Springsteen epitomized. While John F. Kennedy and Ronald Reagan delivered their famous speeches from the safety of West Berlin, Springsteen's speaking out against the Wall in the middle of East Berlin added to the euphoria. + +David Hasselhoff, 1989 +On 31 December 1989, American TV actor and pop music singer David Hasselhoff was the headlining performer for the Freedom Tour Live concert, which was attended by over 500,000 people on both sides of the Wall. The live concert footage was directed by music video director Thomas Mignone and aired on broadcast television station Zweites Deutsches Fernsehen ZDF throughout Europe. During shooting, film crew personnel pulled people up from both sides to stand and celebrate on top of the wall. Hasselhoff sang his number one hit song "Looking For Freedom" on a platform at the end of a twenty-meter steel crane that swung above and over the Wall adjacent to the Brandenburg Gate. A small museum was created in 2008 to celebrate Hasselhoff in the basement of the Circus Hostel. + +Comments by politicians + +On 26 June 1963, 22 months after the erection of the Berlin Wall, U.S. President John F. Kennedy visited West Berlin. Speaking from a platform erected on the steps of Rathaus Schöneberg for an audience of 450,000 and straying from the prepared script, he declared in his Ich bin ein Berliner speech the support of the United States for West Germany and the people of West Berlin in particular: + +The message was aimed as much at the Soviets as it was at Berliners and was a clear statement of U.S. policy in the wake of the construction of the Berlin Wall. The speech is considered one of Kennedy's best, both a significant moment in the Cold War and a high point of the New Frontier. It was a great morale boost for West Berliners, who lived in an exclave deep inside East Germany and feared a possible East German occupation. + +Former British prime minister Margaret Thatcher commented in 1982: + +In a speech at the Brandenburg Gate commemorating the 750th anniversary of Berlin on 12 June 1987, U.S. President Ronald Reagan challenged Mikhail Gorbachev, then the General Secretary of the Communist Party of the Soviet Union, to tear down the Wall as a symbol of increasing freedom in the Eastern Bloc: + +In January 1989 GDR leader Erich Honecker predicted that the Wall would stand for 50 or 100 more years if the conditions that had caused its construction did not change. + +Fall + +Due to the increasing economic problems in the Eastern Bloc and the failure of the USSR to intervene in relation to the individual communist states, the brackets of the Eastern Bloc slowly began to loosen from the end of the 1980s. One example is the fall of the communist government in neighboring Poland's 1989 Polish legislative election. Also in June 1989, the Hungarian government began dismantling the electrified fence along its border with Austria (with Western TV crews present) although the border was still very closely guarded and escape was almost impossible. + +The opening of a border gate between Austria and Hungary at the Pan-European Picnic on 19 August 1989, which was based on an idea by Otto von Habsburg to test the reaction of Mikhail Gorbachev, then triggered a peaceful chain reaction, at the end of which there was no longer the GDR and the Eastern Bloc had disintegrated. Because with the non-reaction of the USSR and the GDR to the mass exodus, the media-informed Eastern Europeans could feel the increasing loss of power of their governments and more and more East Germans were now trying to flee via Hungary. Erich Honecker explained to the Daily Mirror regarding the Paneuropean picnic and thus showed his people his own inaction: "Habsburg distributed leaflets far into Poland, on which the East German holidaymakers were invited to a picnic. When they came to the picnic, they were given gifts, food and Deutsche Mark, and then they were persuaded to come to the West." Then, in September, more than 13,000 East German tourists escaped through Hungary to Austria. This set up a chain of events. The Hungarians prevented many more East Germans from crossing the border and returned them to Budapest. These East Germans flooded the West German embassy and refused to return to East Germany. + +The East German government responded by disallowing any further travel to Hungary but allowed those already there to return to East Germany. This triggered similar events in neighboring Czechoslovakia. This time, however, the East German authorities allowed people to leave, provided that they did so by train through East Germany. This was followed by mass demonstrations within East Germany itself. Protest demonstrations spread throughout East Germany in September 1989. Initially, protesters were mostly people wanting to leave to the West, chanting ("We want out!"). Then protestors began to chant ("We are staying here!"). This was the start of what East Germans generally call the "Peaceful Revolution" of late 1989. The protest demonstrations grew considerably by early November. The movement neared its height on 4 November, when half a million people gathered to demand political change, at the Alexanderplatz demonstration, East Berlin's large public square and transportation hub. On 9 October 1989, the police and army units were given permission to use force against those assembled, but this did not deter the church service and march from taking place, which gathered 70,000 people. + +The longtime leader of East Germany, Erich Honecker, resigned on 18 October 1989 and was replaced by Egon Krenz that day. + +The wave of refugees leaving East Germany for the West kept increasing. By early November refugees were finding their way to Hungary via Czechoslovakia, or via the West German Embassy in Prague. This was tolerated by the new Krenz government, because of long-standing agreements with the communist Czechoslovak government, allowing free travel across their common border. However, this movement of people grew so large it caused difficulties for both countries. To ease the difficulties, the politburo led by Krenz decided on 9 November to allow refugees to exit directly through crossing points between East Germany and West Germany, including between East and West Berlin. Later the same day, the ministerial administration modified the proposal to include private, round-trip, and travel. The new regulations were to take effect the next day. + +Günter Schabowski, the party boss in East Berlin and the spokesman for the SED Politburo, had the task of announcing the new regulations. However, he had not been involved in the discussions about the new regulations and had not been fully updated. Shortly before a press conference on 9 November, he was handed a note announcing the changes, but given no further instructions on how to handle the information. These regulations had only been completed a few hours earlier and were to take effect the following day, so as to allow time to inform the border guards. But this starting time delay was not communicated to Schabowski. At the end of the press conference, Schabowski read out loud the note he had been given. A reporter, ANSA's Riccardo Ehrman, asked when the regulations would take effect. After a few seconds' hesitation, Schabowski replied, "As far as I know, it takes effect immediately, without delay". After further questions from journalists, he confirmed that the regulations included the border crossings through the Wall into West Berlin, which he had not mentioned until then. He repeated that it was immediate in an interview with American journalist Tom Brokaw. + +Excerpts from Schabowski's press conference were the lead story on West Germany's two main news programs that night—at 7:17 p.m. on ZDF's heute and at 8 p.m. on ARD's Tagesschau. As ARD and ZDF had broadcast to nearly all of East Germany since the late 1950s and had become accepted by the East German authorities, the news was broadcast there as well simultaneously. Later that night, on ARD's Tagesthemen, anchorman Hanns Joachim Friedrichs proclaimed, "This 9 November is a historic day. The GDR has announced that, starting immediately, its borders are open to everyone. The gates in the Wall stand open wide." + +After hearing the broadcast, East Germans began gathering at the Wall, at the six checkpoints between East and West Berlin, demanding that border guards immediately open the gates. The surprised and overwhelmed guards made many hectic telephone calls to their superiors about the problem. At first, they were ordered to find the "more aggressive" people gathered at the gates and stamp their passports with a special stamp that barred them from returning to East Germany—in effect, revoking their citizenship. However, this still left thousands of people demanding to be let through "as Schabowski said we can". It soon became clear that no one among the East German authorities would take personal responsibility for issuing orders to use lethal force, so the vastly outnumbered soldiers had no way to hold back the huge crowd of East German citizens. Finally, at 10:45 p.m. on 9 November, Harald Jäger, the commander of the Bornholmer Straße border crossing yielded, allowing for the guards to open the checkpoints and allowing people through with little or no identity checking. As the Ossis swarmed through, they were greeted by Wessis waiting with flowers and champagne amid wild rejoicing. Soon afterward, a crowd of West Berliners jumped on top of the Wall, and were soon joined by East German youngsters. The evening of 9 November 1989 is known as the night the Wall came down. + +Another border crossing to the south may have been opened earlier. An account by Heinz Schäfer indicates that he also acted independently and ordered the opening of the gate at Waltersdorf-Rudow a couple of hours earlier. This may explain reports of East Berliners appearing in West Berlin earlier than the opening of the Bornholmer Straße border crossing. + +Thirty years after the fall of the Berlin Wall, The Guardian collected short stories from 9 November 1989 by five German writers who reflect on the day. In this, Kathrin Schmidt remembers comically: 'I downed almost an entire bottle of schnapps'. + +Legacy + +Little is left of the Wall at its original site, which was destroyed almost in its entirety. Three long sections are still standing: an piece of the first (westernmost) wall at the Topography of Terror, site of the former Gestapo headquarters, halfway between Checkpoint Charlie and Potsdamer Platz; a longer section of the second (easternmost) wall along the Spree River near the , nicknamed East Side Gallery; and a third section that is partly reconstructed, in the north at Bernauer Straße, which was turned into a memorial in 1998. Other isolated fragments, lampposts, other elements, and a few watchtowers also remain in various parts of the city. +The former leadership in the Schlesischen Busch in the vicinity of the Puschkinallee—the listed, twelve-meter high watchtower stands in a piece of the wall strip, which has been turned into a park, near the Lohmühleninsel. +The former "Kieler Eck" (Kiel Corner) on Kieler Strasse in Mitte, close to the Berlin-Spandau Schifffahrtskanal—the tower is protected as a historic monument and now surrounded on three sides by new buildings. It houses a memorial site named after the Wallopfer Günter Litfin, who was shot at Humboldthafen in August 1961. The memorial site, which is run by the initiative of his brother Jürgen Liftin, can be viewed after registration. +The former management office at Nieder Neuendorf, in the district of Hennigsdorf of the same name—here is the permanent exhibition on the history of the border installations between the two German states. +The former management station at Bergfelde, today the district of Hohen Neuendorf—The tower is located in an already reforested area of the border strip and is used together with surrounding terrain as a nature protection tower by the Deutschen Waldjugend. +The only one of the much slimmer observation towers (BT-11) in the Erna-Berger-Strasse also in Mitte—however, was moved by a few meters for construction work and is no longer in the original location; There is an exhibition about the wall in the area of the Potsdamer Platz in planning. + +Nothing still accurately represents the Wall's original appearance better than a very short stretch at Bernauer Straße associated with the Berlin Wall Documentation Center. Other remnants are badly damaged by souvenir seekers. Fragments of the Wall were taken and some were sold around the world. Appearing both with and without certificates of authenticity, these fragments are now a staple on the online auction service eBay as well as German souvenir shops. Today, the eastern side is covered in graffiti that did not exist while the Wall was guarded by the armed soldiers of East Germany. Previously, graffiti appeared only on the western side. Along some tourist areas of the city centre, the city government has marked the location of the former Wall by a row of cobblestones in the street. In most places only the "first" wall is marked, except near Potsdamer Platz where the stretch of both walls is marked, giving visitors an impression of the dimension of the barrier system. + +After the fall of the Berlin Wall, there were initiatives that they want to preserve the death strip walkways and redevelop them into a hiking and cycling area, known as . It is part of the initiative by the Berlin Senate since 11 October 2001. + +Cultural differences + +For many years after reunification, people in Germany talked about cultural differences between East and West Germans (colloquially Ossis and Wessis), sometimes described as Mauer im Kopf (The wall in the head). A September 2004 poll found that 25 percent of West Germans and 12 percent of East Germans wished that East and West should be separated again by a "Wall". A poll taken in October 2009 on the occasion of the 20th anniversary of the fall of the Wall indicated, however, that only about a tenth of the population was still unhappy with the unification (8 percent in the East; 12 percent in the West). Although differences are still perceived between East and West, Germans make similar distinctions between North and South. + +A 2009 poll conducted by Russia's VTsIOM, found that more than half of all Russians do not know who built the Berlin Wall. Ten percent of people surveyed thought Berlin residents built it themselves. Six percent said Western powers built it and four percent thought it was a "bilateral initiative" of the Soviet Union and the West. Fifty-eight percent said they did not know who built it, with just 24 percent correctly naming the Soviet Union and its then-communist ally East Germany. + +Wall segments around the world + +Not all segments of the Wall were ground up as the Wall was being torn down. Many segments have been given to various institutions in the world. They can be found, for instance, in presidential and historical museums, lobbies of hotels and corporations, at universities and government buildings, and in public spaces in different countries of the world. + +50th anniversary commemoration +On 13 August 2011, Germany marked the 50th anniversary of East Germany beginning the erection of the Berlin Wall. Chancellor Angela Merkel joined with President Christian Wulff and Berlin Mayor Klaus Wowereit at the Bernauer Straße memorial park to remember lives and liberty. Speeches extolled freedom and a minute of silence at noon honored those who died trying to flee to the West. "It is our shared responsibility to keep the memory alive and to pass it on to the coming generations as a reminder to stand up for freedom and democracy to ensure that such injustice may never happen again." entreated Mayor Wowereit. "It has been shown once again: Freedom is invincible at the end. No wall can permanently withstand the desire for freedom", proclaimed President Wulff. + +Related media + +Documentaries + +Documentary films specifically about the Berlin Wall include: +The Tunnel (December 1962), an NBC News Special documentary film. +The Road to the Wall (1962), a documentary film. +Something to Do with the Wall (1991), a documentary about the fall of the Berlin Wall by Ross McElwee and Marilyn Levine, originally conceived as a commemoration of the 25th anniversary of its construction. +Rabbit à la Berlin (2009), a documentary film, directed by Bartek Konopka, told from the point of view of a group of wild rabbits that inhabited the zone between the two walls. +The American Sector (2020), a documentary by Courtney Stephens and Pacho Velez that tracks down the wall segments located in the U.S. + +Feature films + +Fictional films featuring the Berlin Wall have included: +Escape from East Berlin (1962), American-West German film inspired by story of 29 East Germans that tunneled under the wall +The Spy Who Came in from the Cold (1965), a Cold War classic set on both sides of The Wall, from the eponymous book by John le Carré, directed by Martin Ritt. +The Boy and the Ball and the Hole in the Wall (1965), Spanish-Mexican co-production. +Funeral in Berlin (1966), a spy movie starring Michael Caine, directed by Guy Hamilton. +Casino Royale (1967), a film featuring a segment centred on a house apparently bisected by the Wall. +The Wicked Dreams of Paula Schultz (1968), a Cold War spy farce about an Olympic athlete who defects, directed by George Marshall. +Berlin Tunnel 21 (1981), a made-for-TV movie about a former American officer leading an attempt to build a tunnel underneath The Wall as a rescue route. +Night Crossing (1982), a British-American drama film starring John Hurt, Jane Alexander, and Beau Bridges, based on the true story of the Strelzyk and Wetzel families, who on 16 September 1979, attempted to escape from East Germany to West Germany in a homemade hot air balloon, during the days of the Inner German border-era. +The Innocent (1993), a film about the joint CIA/MI6 operation to build a tunnel under East Berlin in the 1950s, directed by John Schlesinger. +Sonnenallee (1999), a German comedy film about life in East Berlin in the late 1970s, directed by Leander Haußmann. +The Tunnel (2001), a dramatization of a collaborative tunnel under the Wall, filmed by Roland Suso Richter. +Good Bye Lenin!

They belong to different families of instruments and can cover a wide range of musical roles. Since producing low pitches usually requires a long air column or string, and for stringed instruments, a large hollow body, the string and wind bass instruments are usually the largest instruments in their families or instrument classes. + +Musical role +When bass notes are played in a musical ensemble such an orchestra, they are frequently used to provide a counterpoint or counter-melody, in a harmonic context either to outline or juxtapose the progression of the chords, or with percussion to underline the rhythm. + +Rhythm section +In popular music, the bass part, which is called the "bassline", typically provides harmonic and rhythmic support to the band. The bass player is a member of the rhythm section in a band, along with the drummer, rhythm guitarist, and, in some cases, a keyboard instrument player (e.g., piano or Hammond organ). The bass player emphasizes the root or fifth of the chord in their basslines (and to a lesser degree, the third of the chord) and accents the strong beats. + +Kinds of bass harmony +In classical music, different forms of bass are: basso concertante, or basso recitante; the bass voice of the chorus; the bass which accompanies the softer passages of a composition, as well as those passages which employ the whole power of the ensemble, generally played by the violoncellos in orchestral music; contrabass (“under bass”), is described as that part which is performed by the double basses; violoncellos often play the same line an octave higher, or a different melodic or rhythmic part which is not a bassline when double basses are used; basso ripieno; that bass which joins in the full passages of a composition, and, by its depth of tone and energy of stroke, affords a powerful contrast to the lighter and softer passages or movements. + +Basso continuo was an approach to writing music during the Baroque music era (1600-1750). With basso continuo, a written-out bassline served to set out the chord progression for an entire piece (symphony, concerto, Mass, or other work), with the bassline being played by pipe organ or harpsichord and the chords being improvised by players of chordal instruments (theorbo, lute, harpsichord, etc.). + +"The bass differs from other voices because of the particular role it plays in supporting and defining harmonic motion. It does so at levels ranging from immediate, chord-by-chord events to the larger harmonic organization of an entire work." + +Instruments +As seen in the musical instrument classification article, categorizing instruments can be difficult. For example, some instruments fall into more than one category. The cello is considered a tenor instrument in some orchestral settings, but in a string quartet it is the bass instrument. Also, the Bass Flute is actually the tenor member of the flute family even though it is called the "Bass" Flute. + +Examples grouped by general form and playing technique include: +Double bass from the viol or violin family (usually the instrument referred to as a "bass" in European classical music and jazz. Sometimes called a "string bass" to differentiate it from a "brass bass" or "bass horn", or an "upright bass" to differentiate it from a "bass guitar") +Bass guitar and acoustic bass guitar, instruments shaped, constructed and held (or worn) like guitars, that play in the bass range. The electric bass guitar is usually the instrument referred to as a "bass" in pop and rock music. +A bass horn, such as a tuba, serpent, and sousaphone from the wind family and low-tuned versions of specific types of brass and woodwind instruments, such as bassoon, bass clarinet, bass trombone and bass saxophone, etc. (less common usage) +Keyboard bass, a keyboard alternative to the bass guitar or double bass (e.g. the Fender Rhodes piano bass in the 1960s or 13-note MIDI keyboard controllers in the 2000s) +Washtub bass, a simple folk instrument + +A musician playing one of these instruments is often known as a bassist.

While some hi-fi aficionados had solved the problem by using other playback sources, such as reel-to-reel tape players which were capable of delivering accurate, naturally deep bass from acoustic sources, or synthetic bass not found in nature, with the popular introduction of the compact cassette in the late 1960s it became possible to add more low-frequency content to recordings. By the mid-1970s, 12" vinyl singles, which allowed for "more bass volume", were used to record disco, reggae, dub and hip-hop tracks; dance club DJs played these records in clubs with subwoofers to achieve "physical and emotional" reactions from dancers. + +In the early 1970s, early disco DJs sought out deeper bass sounds for their dance events. David Mancuso hired sound engineer Alex Rosner to design additional subwoofers for his disco dance events, along with "tweeter arrays" to "boost the treble and bass at opportune moments" at his private, underground parties at The Loft. The demand for sub-bass sound reinforcement in the 1970s was driven by the important role of "powerful bass drum" in disco, as compared with rock and pop; to provide this deeper range, a third crossover point from 40 Hz to 120 Hz (centering on 80 Hz) was added. The Paradise Garage discotheque in New York City, which operated from 1977 to 1987, had "custom designed 'sub-bass' speakers" developed by Alex Rosner's disciple, sound engineer Richard ("Dick") Long that were called "Levan Horns" (in honor of resident DJ Larry Levan). + +By the end of the 1970s, subwoofers were used in dance venue sound systems to enable the playing of "[b]ass-heavy dance music" that we "do not 'hear' with our ears but with our entire body". At the club, Long used four Levan bass horns, one in each corner of the dancefloor, to create a "haptic and tactile quality" in the sub-bass that you could feel in your body. To overcome the lack of sub-bass frequencies on 1970s disco records (sub-bass frequencies below 60 Hz were removed during mastering), Long added a DBX 100 "Boom Box" subharmonic pitch generator into his system to synthesize 25 Hz to 50 Hz sub-bass from the 50 to 100 Hz bass on the records. In the early 1980s, Long designed a sound system for the Warehouse dance club, with "huge stacks of subwoofers" which created "deep and intense" bass frequencies that "pound[ed] through your system" and "entire body", enabling clubgoers to "viscerally experience" the DJs' house music mixes. + +Deep, heavy bass is central to Jamaican musical styles such as dub and reggae. In Jamaica in the 1970s and 1980s, sound engineers for reggae sound systems began creating "heavily customized" subwoofer enclosures by adding foam and tuning the cabinets to achieve "rich and articulate speaker output below 100 Hz". The sound engineers who developed the "bass-heavy signature sound" of sound reinforcement systems have been called "deserving as much credit for the sound of Jamaican music as their better-known music producer cousins". The sound engineers for Stone Love Movement (a sound system crew), for example, modified folded horn subwoofers they imported from the US to get more of a bass reflex sound that suited local tone preferences for dancehall audiences, as the unmodified folded horn was found to be "too aggressive" sounding and "not deep enough for Jamaican listeners". + +In Jamaican sound system culture, there are both "low and high bass bins" in "towering piles" that are "delivered in large trucks" and set up by a crew of "box boys", and then positioned and adjusted by the sound engineer in a process known as "stringing up", all to create the "sound of reggae music you can literally feel as it comes off these big speakers". Sound system crews hold 'sound clash' competitions, where each sound system is set up and then the two crews try to outdo each other. + +Movies +The use of subwoofers to provide deep bass in film presentations received a great deal of publicity in 1974 with the movie Earthquake which was released in Sensurround. Initially installed in 17 U.S. theaters, the Cerwin Vega "Sensurround" system used large subwoofers which were driven by racks of 500 watt amplifiers which were triggered by control tones printed on one of the audio tracks on the film. Four of the subwoofers were positioned in front of the audience under (or behind) the film screen and two more were placed together at the rear of the audience on a platform. Powerful noise energy and loud rumbling in the range of 17 Hz to 120 Hz was generated at the level of 110–120 decibels of sound pressure level, abbreviated dB(SPL). The new low frequency entertainment method helped the film become a box office success. More Sensurround systems were assembled and installed. By 1976 there were almost 300 Sensurround systems leapfrogging through select theaters. Other films to use the effect include Midway in 1976 and Rollercoaster in 1977. + +See also +Sub bass +Treble (sound) +Bass clef +Figured bass + +Sources + +Further reading + +External links + + +Contrabass instruments +UK bass, also called bass music, is club music that emerged in the United Kingdom during the mid-2000s under the influence of diverse genres such as house, grime, dubstep, UK garage, R&B, and UK funky. The term "UK bass" came into use as artists began ambiguously blending the sounds of these defined genres while maintaining an emphasis on percussive, bass-led rhythm. + +UK bass is sometimes conflated with bassline or post-dubstep. It is not to be confused with the hip hop and electro-based genre Miami bass, which is sometimes called "bass music" as well. + +Origins +The breadth of styles that have come to be associated with the term preclude it from being a specific musical genre. Pitchfork writer Martin Clark has suggested that "well-meaning attempts to loosely define the ground we're covering here are somewhat futile and almost certainly flawed. This is not one genre. However, given the links, interaction, and free-flowing ideas ... you can't dismiss all these acts as unrelated." Dubstep producer Skream is quoted in an interview with The Independent in September 2011 as saying: The word dubstep is being used by a lot of people and there were a lot of people being tagged with the dubstep brush. They don't want to be tagged with it and shouldn't be tagged with it – that's not what they're pushing... When I say 'UK bass', it's what everyone UK is associated with so it would be a lot easier if it was called that." + +In the United Kingdom, bass music has had major mainstream success since the late 2000s and early 2010s, with artists such as James Blake, Benga, Burial, SBTRKT, Sophie, Rustie, Zomby, and Skream. The term "post-dubstep" has been used synonymously to refer to artists, such as Blake and Mount Kimbie whose work draws on UK garage, 2-step, and other forms of underground dance music, as well as ambient music and early R&B. Outside of nightclubs, UK bass has mainly been promoted and played on Internet radio stations such as Sub.FM and Rinse FM. + +References + +2000s in music +2010s in music +21st-century music genres +British styles of music +Dubstep +Electronic dance music genres +A burning glass or burning lens is a large convex lens that can concentrate the sun's rays onto a small area, heating up the area and thus resulting in ignition of the exposed surface. Burning mirrors achieve a similar effect by using reflecting surfaces to focus the light. They were used in 18th-century chemical studies for burning materials in closed glass vessels where the products of combustion could be trapped for analysis. The burning glass was a useful contrivance in the days before electrical ignition was easily achieved. + +Historical development: from legend to science + +Burning glass technology has been known since antiquity, as described by Greek and Roman writers who recorded the use of lenses to start fires for various purposes. Pliny the Elder noted the use of glass vases filled with water to concentrate sunlight heat intensely enough to ignite clothing, as well as convex lenses that were used to cauterize wounds. Plutarch refers to a burning mirror made of joined triangular metal mirrors installed at the temple of the Vestal Virgins. Aristophanes mentions the burning lens in his play The Clouds (424 BC). + +The Hellenistic Greek mathematician Archimedes was said to have used a burning glass as a weapon in 212 BC, when Syracuse was besieged by Marcus Claudius Marcellus of the Roman Republic. The Roman fleet was supposedly incinerated, though eventually the city was taken and Archimedes was slain. + +The legend of Archimedes gave rise to a considerable amount of research on burning glasses and lenses until the late 17th century. Various researchers from medieval Christendom to the Islamic world worked with burning glasses, including Anthemius of Tralles (6th century AD), Proclus (6th century; who by this means purportedly destroyed the fleet of Vitalian besieging Constantinople), Ibn Sahl in his On Burning Mirrors and Lenses (10th century), Alhazen in his Book of Optics (1021), Roger Bacon (13th century), Giambattista della Porta and his friends (16th century), Athanasius Kircher and Gaspar Schott (17th century), and the Comte de Buffon in 1740 in Paris. + +While the effects of camera obscura were mentioned by Greek philosopher Aristotle in the 4th century BC, contemporary Chinese Mohists of China's Warring States Period who compiled the Mozi described their experiments with burning mirrors and the pinhole camera. A few decades after Alhazen described camera obscura in Iraq, the Song dynasty Chinese statesman Shen Kuo was nevertheless the first to clearly describe the relationship of the focal point of a concave mirror, the burning point and the pinhole camera as separate radiation phenomena in his Dream Pool Essays (1088). By the late 15th century Leonardo da Vinci would be the first in Europe to make similar observations about the focal point and pinhole. + +Burning lenses were used in the 18th century by both Joseph Priestley and Antoine Lavoisier in their experiments to obtain oxides contained in closed vessels under high temperatures. These included carbon dioxide by burning diamond, and mercuric oxide by heating mercury. This type of experiment contributed to the discovery of "dephlogisticated air" by Priestley, which became better known as oxygen, following Lavoisier's investigations. + +Chapter 17 of William Bates' 1920 book Perfect Sight Without Glasses, in which the author argues that observation of the sun is beneficial to those with poor vision, includes a figure of somebody "Focussing the Rays of the Sun Upon the Eye of a Patient by Means of a Burning Glass." + +The burning lens of the Grand Duke of Tuscany was used by Sir Humphry Davy and Michael Faraday to burn a diamond in oxygen on the 27th March 1814. + +Use + +War: since the legend of Archimedes +The first story akin to that of burning glass is by Archimedes, for the purpose of war, in 212 BC. When Syracuse was besieged by Marcus Claudius Marcellus, the Roman fleet was supposedly incinerated by the use of not glass per se, but a concave mirror made of brass focusing sunlight. Whether or not that actually happened, eventually the city was taken and Archimedes was slain. + +In 1796, during the French Revolution and three years after the declaration of war between France and Great Britain, physicist Étienne-Gaspard Robert met with the French government and proposed the use of mirrors to burn the invading ships of the British Royal Navy. They decided not to take up his proposal. + +Domestic use: primitive fire making + +Burning glasses (often called fire lenses) are still used to light fires in outdoor and primitive settings. Large burning lenses sometimes take the form of Fresnel lenses, similar to lighthouse lenses, including those for use in solar furnaces. Solar furnaces are used in industry to produce extremely high temperatures without the need for fuel or large supplies of electricity. They sometimes employ a large parabolic array of mirrors (some facilities are several stories high) to focus light to a high intensity. + +Religion: sacred fire +In various religions settings, a burning glass is used to set off some sort of sacred fire. + +From the 7th to the 16th centuries, a burning glass was used by Christians to set off the Easter Fire during the Easter vigil. Thus, Saint Boniface explained to Pope Zachary that he produced the new fire of Holy Saturday by means of a crystal lens concentrating the rays of the sun. This process was also mentioned in liturgical books until the Roman Pontifical of 1561. + +In Cambodia, a burning glass has also been used since ancient times for the cremation of kings and most recently for the funeral of King Sihanouk. The crematorium of the king is traditionally prepared by the Bakus brahmin from the Royal Palace on the last day of the week-long funeral. Small pieces of fragrant agarwood are placed beneath the magnifying glass until it ignites. The incandescent wood is used to light candles and pass on the fire to the attendees, who usually take their lit candles home. + +Sports: lighting the Olympic torch +The Olympic torch that is carried around the host country of the Olympic Games is lit by a burning glass, at the site of ancient Olympia in Greece. + +Popular culture: verification attempts +There have been several real-world tests to evaluate the validity of the legend of Archimedes described above over the centuries, including a test by Comte de Buffon (circa 1747), documented in the paper titled "Invention De Miroirs Ardens, Pour Brusler a Une Grande Distance", and an experiment by John Scott, which was documented in an 1867 paper. +In 1973, Greek scientist Dr. Ioannis Sakkas, curious about whether Archimedes could really have used a "burning glass" to destroy the Roman fleet in 212 BC, lined up nearly 60 Greek sailors, each holding an oblong mirror tipped to catch the sun’s rays and direct them at a wooden ship 160 feet away. The ship caught fire at once. Sakkas said after the experiment there was no doubt in his mind the great inventor could have used bronze mirrors to scuttle the Romans. + +However, accounting for battle conditions makes such a weapon impractical, with modern tests refuting such claims. An experiment was carried out by a group at the Massachusetts Institute of Technology in 2005. It concluded that although the theory was sound for stationary objects, the mirrors would not likely have been able to concentrate sufficient solar energy to set a ship on fire under battle conditions. Similar experiments were conducted on the popular science-based TV show MythBusters in 2004, 2006, and 2010, arriving at similar results based on the premise of the controversial myth. + +However, an episode of Richard Hammond's Engineering Connections relating to the Keck Observatory (whose reflector glass is based on the Archimedes' Mirror) did successfully use a much smaller curved mirror to burn a wooden model, although the scaled-down model was not made of the same quality of materials as in the MythBusters effort. + +See also + Diocles (mathematician) + Nimrud lens + Pyreliophorus + Visby lenses + Solar furnace + +References + +Further reading +Temple, Robert.

A common example is the lighthouse, which draws attention to a fixed point that can be used to navigate around obstacles or into port. More modern examples include a variety of radio beacons that can be read on radio direction finders in all weather, and radar transponders that appear on radar displays. + +Beacons can also be combined with semaphoric or other indicators to provide important information, such as the status of an airport, by the colour and rotational pattern of its airport beacon, or of pending weather as indicated on a weather beacon mounted at the top of a tall building or similar site. When used in such fashion, beacons can be considered a form of optical telegraphy. + +For navigation + +Beacons help guide navigators to their destinations. Types of navigational beacons include radar reflectors, radio beacons, sonic and visual signals. Visual beacons range from small, single-pile structures to large lighthouses or light stations and can be located on land or on water. Lighted beacons are called lights; unlighted beacons are called daybeacons. Aerodrome beacons are used to indicate locations of airports and helipads. + +Handheld beacons are also employed in aircraft marshalling, and are used by the marshal to deliver instructions to the crew of aircraft as they move around an active airport, heliport or aircraft carrier. + +For defensive communications (historical) + +Historically, beacons were fires lit at well-known locations on hills or high places, used either as lighthouses for navigation at sea, or for signalling over land that enemy troops were approaching, in order to alert defenses. As signals, beacons are an ancient form of optical telegraph and were part of a relay league. + +Systems of this kind have existed for centuries over much of the world. The ancient Greeks called them phryctoriae, while beacons figure on several occasions on the column of Trajan. + +In imperial China, sentinels on and near the Great Wall of China used a sophisticated system of daytime smoke and nighttime flame to send signals along long chains of beacon towers. + +Legend has it that King You of Zhou played a trick multiple times in order to amuse his often melancholy concubine, ordering beacon towers lit to fool his vassals and soldiers. But when enemies, led by the Marquess of Shen really arrived at the wall, although the towers were lit, no defenders came, leading to King Yōu's death and the collapse of the Western Zhou dynasty. China's system of beacon towers was not extant prior to the Han dynasty. + +Thucydides wrote that during the Peloponnesian War, the Peloponnesians who were in Corcyra were informed by night-time beacon signals of the approach of sixty Athenian vessels from Lefkada. + +In the 10th century, during the Arab–Byzantine wars, the Byzantine Empire used a beacon system to transmit messages from the border with the Abbasid Caliphate, across Anatolia to the imperial palace in the Byzantine capital, Constantinople. It was devised by Leo the Mathematician for Emperor Theophilos, but either abolished or radically curtailed by Theophilos' son and successor, Michael III. Beacons were later used in Greece as well, while the surviving parts of the beacon system in Anatolia seem to have been reactivated in the 12th century by Emperor Manuel I Komnenos. + +In Scandinavia many hill forts were part of beacon networks to warn against invading pillagers. In Finland, these beacons were called vainovalkeat, "persecution fires", or vartiotulet, "guard fires", and were used to warn Finn settlements of imminent raids by the Vikings. + +In Wales, the Brecon Beacons were named for beacons used to warn of approaching English raiders. In England, the most famous examples are the beacons used in Elizabethan England to warn of the approaching Spanish Armada. Many hills in England were named Beacon Hill after such beacons. In England the authority to erect beacons originally lay with the King and later was delegated to the Lord High Admiral. The money due for the maintenance of beacons was called Beaconagium and was levied by the sheriff of each county. In the Scottish borders country, a system of beacon fires was at one time established to warn of incursions by the English. Hume and Eggerstone castles and Soltra Edge were part of this network. + +In Spain, the border of Granada in the territory of the Crown of Castile had a complex beacon network to warn against Moorish raiders and military campaigns. Due to the progressive advance of the borders throughout the process of the Reconquista, the entire Spanish geography is full of defensive lines of castles, towers and fortifications, visually connected to each other, which served as fortified beacons. Some examples are the Route of the Vinalopó castles or the distribution of the castles in Jaén. + +Military use (20th–21st century) + +Infrared marker + +Infrared strobes and other infrared beacons have increasingly been used in modern combat when operating at night as they can only be seen through night vision goggles. As a result, they are often used to mark friendly positions as a form of IFF to prevent friendly fire and improve coordination. Soldiers will typically affix them to their helmets or other gear so they are easily visible to others using night vision including other infantry, ground vehicles, and aerial platforms (drones, helicopters, planes, etc). + +Passive markers include IR patches, which reflect infrared light, and chemlights. The earliest such beacons were often IR chemlights taped to helmets. + +As time went on, more sophisticated options began to emerge with electronically powered infrared strobes with specific mounting solutions for attaching to helmets or load bearing equipment.

Emergency vehicles such as fire engines, ambulances, police cars, tow trucks, construction vehicles, and snow-removal vehicles carry beacon lights. + +The color of the lamps varies by jurisdiction; typical colors are blue and/or red for police, fire, and medical-emergency vehicles; amber for hazards (slow-moving vehicles, wide loads, tow trucks, security personnel, construction vehicles, etc.); green for volunteer firefighters or for medical personnel, and violet for funerary vehicles. Beacons may be constructed with halogen bulbs similar to those used in vehicle headlamps, xenon flashtubes, or LEDs. Incandescent and xenon light sources require the vehicle's engine to continue running to ensure that the battery is not depleted when the lights are used for a prolonged period. The low power consumption of LEDs allows the vehicle's engine to remain turned off while the lights operate. + +Other uses +Beacons and bonfires are also used to mark occasions and celebrate events. + +Beacons have also allegedly been abused by shipwreckers. An illicit fire at a wrong position would be used to direct a ship against shoals or beaches, so that its cargo could be looted after the ship sank or ran aground. There are, however, no historically substantiated occurrences of such intentional shipwrecking. + +In wireless networks, a beacon is a type of frame which is sent by the access point (or WiFi router) to indicate that it is on. + +Bluetooth based beacons periodically send out a data packet and this could be used by software to identify the beacon location. This is typically used by indoor navigation and positioning applications. + +Beaconing is the process that allows a network to self-repair network problems. The stations on the network notify the other stations on the ring when they are not receiving the transmissions.

R. R. Tolkien's high fantasy novel, The Lord of the Rings, a series of beacons alerts the entire realm of Gondor when the kingdom is under attack. These beacon posts were staffed by messengers who would carry word of their lighting to either Rohan or Belfalas. In Peter Jackson's film adaptation of the novel, the beacons serve as a connection between the two realms of Rohan and Gondor, alerting one another directly when they require military aid, as opposed to relying on messengers as in the novel. + +In publishing +The Beacon was an influential Caribbean magazine published in Trinidad in the 1930s.

It is a type of upbeat popular music associated with the Punjabi diaspora in Britain. The style has its origins in the folk music of Punjab as well as western pop music of the 1970s and 1980s. Prior to this musical fusion, Bhangra existed only as a dance form in the native Punjab. This Punjabi music was unique in that it was not traditional nor did it seek any authenticity. While the traditional folk music of Punjab has a set of melodies that are used by various singers, Bhangra was a form of strict "band culture" in that new melodies were composed for each song. Therefore, the musicians were as important as the singers. + +Origins +The roots of modern bhangra music date back to the Sikh Punjabi community in Punjab during the 1960s. An early pop music and modern recording group of this type of music in the United Kingdom was Bhujhangy Group, founded by Tarlochan Singh Bilga, Balbir Singh Khanpur, Gurpal, Rajinder Dhona and Dalvir Kahanpuri in Birmingham in 1971. Bhujhangy Group's first major hit was "Bhabiye Akh Larr Gayee". It was written by Tarlochan Singh Bilga in the early 1975s and was released on Birmingham's Oriental Star Agencies label. This was the first song to combine traditional Asian music with modern Western instruments. + +Differences from folk music +Although bhangra music used many of the elements of Punjabi folk music (e.g., "Bakkrey Bulaaney" – the goat herding vocalizations), it was also radically different in its embrace of modernity. The song structure of a typical bhangra song featured four verses, a chorus, along with two alternating instrumental bridge sections. (e.g., CVB1CVB2CVB1CVB2C.) Hence it featured more musicianship than its folk predecessor. + +United Kingdom + +1970s +A modern and commercial form of bhangra music was said to rise in Britain in the 1970s by Punjabi immigrants who took their native folk music and began experimenting by altering it using instruments from their host country. The new genre quickly became popular in Britain replacing Punjabi folk singers due to it being heavily influenced in Britain by the infusion of rock music and a need to move away from the simple and repetitive Punjabi folk music. It indicated the development of a self-conscious and distinctively rebellious British Asian youth culture centred on an experiential sense of self, e.g., language, gesture, bodily signification, desires, etc., in a situation in which tensions with British culture and racist elements in British society had resulted in alienation in many minority ethnic groups, fostered a sense of need for an affirmation of a positive identity and culture, and provided a platform for British Punjabi males to assert their masculinity. + +In the 1980s, distributed by record labels such as Multitone Records, bhangra artists were selling over 30,000 cassettes a week in the UK, but no artists reached the Top 40 UK chart despite these artists outselling popular British ones; most of the bhangra cassette sales were not through the large UK record stores, whose sales were those recorded by the Official UK Charts Company for creating their rankings. + +The group Alaap was formed in 1977, co-founded by Channi Singh and Harjeet Gandhi who both hailed from Southall, a Punjabi area in London. Their album Teri Chunni De Sitaray was released in 1982 by Multitone. Alaap was considered the first and original superstar bhangra band formed in the United Kingdom. Channi Singh has been awarded the OBE by the Queen for his services to Bhangra music and services/charity for the British Asian community. Co-founder Harjeet Gandhi died in 2003. + +The 1980s is commonly known as the golden age, or the age of bhangra music, which lasted roughly from 1985 to 1993. The primary emphasis during these times was on the melody/riff, played out usually on a synthesizer, harmonium, accordion or guitar. Folk instruments were rarely used. + +One of the biggest bhangra stars of the last several decades is Malkit Singh and his band Golden Star. Singh was born in June 1963 in the village of Hussainpur in Punjab. He attended the Lyallpur Khalsa College, Jalandhar, in Punjab in 1980 to study for a bachelor of arts degree. There he met his mentor, Professor Inderjit Singh, who taught him Punjabi folk singing and bhangra dancing. Due to Singh's tutelage, Malkit entered and won song contests during this time. In 1983, he won a gold medal at the Guru Nanak Dev University in Amritsar, Punjab, for performing his song "Gurh Nalon Ishq Mitha", which later featured on his first album, Nach Gidhe Wich. The lyrics were by Tarlochan Singh Bilga and it was released in 1985. This album was created with Manager, Tarlochan Singh Bilga(TSB). The band has toured 27 countries. Malkit has been awarded the MBE by the Queen for his services to Bhangra music. + +Bhangra boy band, the Sahotas, were composed of five brothers from Wolverhampton. Their music is a fusion of bhangra, rock and dance. + +Heera, formed by Bhupinder Bhindi and fronted by Kumar and Dhami, was one of the most popular bands of the 1980s. + +Bands like Alaap and Heera incorporated rock-influenced beats into bhangra, because it enabled "Asian youth to affirm their identities positively" within the broader environment of alternative rock as an alternative way of expression. However, some believe that the progression of bhangra music created an "intermezzo culture" post-India's partition, within the unitary definitions of Southeast Asians within the diaspora, thus "establishing a brand new community in their home away from home". + +Several other influential groups appeared around the same time, including The Saathies, Premi Group, Bhujungy Group, and Apna Sangeet. Apna Sangeet, best known for their hit "Mera Yaar Vajavey Dhol", re-formed for charity in May 2009 after a break-up. + +When Bhangra and General Indian sounds and lyrics were combined, British-Asian artists began incorporating them in their music. Some Asian artists such as Bally Sagoo and Talvin Singh are creating their own form of British hip-hop. + +This era also brought about bhangra art, which like the bhangra music it represented was rebellious. Unlike folk music art, which consisted of a picture of the folk singer, bhangra recordings had details such as distinctive artwork, logos, clever album names and band/musician listings (who played what). + +Folk backlash +Unlike bhangra, folk music depends on a set number of traditional melodies that may be hundreds of years old. Each new singer simply writes new lyrics using one of those melodies. + +In the mid-1990s, many artists, attracted to the economics of a bandless singer only act that technology such as karaoke machines now enabled, returned to the original, traditional folk beats away from bhangra music, often incorporating more dhol drum beats and tumbi. This time also saw the rise of several young Punjabi folk singers as a backlash to bhangra music. They were aided by DJs who mixed hip-hop samples with folk singing. + +Beginning around 1994, there was a trend towards the use of samples (often sampled from mainstream hip hop) mixed with traditional folk rhythm instruments, such as the tumbi and dhol. Using folk instruments and hip-hop samples, along with relatively inexpensive folk vocals imported from Punjab, Punjabi folk music was able to cause the decline of bhangra music. + +Pioneering DJs instrumental in the decline of bhangra were Bally Sagoo and Panjabi MC. As DJs who were initially hired by bhangra labels to remix the original recordings on the label's roster (OSA and Nachural respectively), they along with the record labels quickly found that remixing folk singers from India was much cheaper than working with outsourced bhangra bands. + +A pioneering folk singer that was instrumental in bhangra's demise was Jazzy B, who debuted in 1992. Having sold over 55,000 copies of his third album, Folk and Funky, he is now one of the best-selling Punjabi folk artists in the world, with a vocal style likened to that of Kuldip Manak. + +Other influential folk artists include Surinder Shinda – famous for his "Putt Jattan De" – Harbhajan Mann, Manmohan Waris, Sarbjit Cheema, Hans Raj Hans, Sardool Sikander, B21, Paaras and Bombay Talkie. + +By the end of the 1990s, bhangra music had largely declined and been replaced with Punjabi folk singers. The same folk singers which bhangra bands had replaced a decade earlier were being utilized by DJs to make relatively inexpensive live music on laptops. This "folkhop" genre was short lived as records could not be officially released due to nonclearance copyrights on samples used to create the "beat". This continued until the end of the century. Folk-hop record labels such as Hi-Tech were investigated by BPI (British Phonographic Industry) for copyright infringement by way of uncleared samples on releases by folk DJs such as DJ Sanj. + +Toward the end of the decade, bhangra continued to decline, with folk-hop artists such as Bally Sagoo and Apache Indian signing with international recording labels Sony and Island. Moreover, Multitone Records, one of the major recording labels associated with bhangra in Britain in the 1980s and 1990s, was bought by BMG. A recent Pepsi commercial launched in Britain featured South Asian actors and Punjabi folk music. + +2000s remixes + +Punjabi folk remixed with hip-hop, known as folkhop, is most often produced when folk vocals are purchased online to be remixed in a studio. Folk vocals are usually sung to traditional melodies, that are often repeated with new lyrics. + +Some South Asian DJs, especially in America, have mixed Punjabi folk music with house, reggae, and hip-hop to add a different flavor to Punjabi folk. These remixes continued to gain popularity as the 1990s came to an end. + +A notable remix artist is Bally Sagoo, a Punjabi-Sikh, Anglo-Indian raised in Birmingham, England. Sagoo described his music as "a bit of tablas, a bit of the Indian sound. But bring on the bass lines, bring on the funky-drummer beat, bring on the James Brown samples", to Time magazine in 1997. He was recently signed by Sony. Daler Mehndi, a Punjabi singer from India has a type of music known as "folk pop". Mehndi has released tracks such as "Bolo Ta Ra Ra" and "Ho Jayegee Balle Balle". His song "Tunak Tunak Tun" was released in 1998. + +Canada and the United States + +Punjabi immigrants have encouraged the growth of Punjabi folk music in the Western hemisphere rather than bhangra music. The bhangra industry has grown in North America much less than in the United Kingdom. + +North American (non bhangra) folk artists such as Manmohan Waris, Jazzy Bains, Kamal Heer, Harbhajan Mann, Sarabjit Cheema, and Debi Makhsoospuri have emerged and the remix market has grown. + +In 2001, Punjabi folk, and its hip-hop form, folkhop, began to exert an influence over US R&B music, when Missy Elliott released the folkhop-influenced song "Get Ur Freak On". In 2003, a version of Panjabi MC's "Mundian To Bach Ke" ("Beware of the Boys") featured U.S. rapper Jay-Z. Additionally, American rapper Pras of The Fugees recorded tracks with British alternative bhangra band Swami. American singer and actress Selena Gomez released her bhangra-influenced single "Come & Get It" from her first solo album Stars Dance in 2013. + +Lyrics + +Bhangra lyrics, which generally cover social issues or love, are sung in Punjabi. Bhangra lyrics were generally kept deliberately simple by the creators of the genre because the youth did not understand complex lyrics. Traditional Punjabi folk lyrics are generally more complex and often tell the tales of Punjabi history. There are many bhangra songs devoted to Punjabi pride themes and Punjabi heroes. The lyrics are tributes to the cultural traditions of Punjab. In particular, many bhangra tracks have been written about Udham Singh and Bhagat Singh. Less serious topics include beautiful women with their colourful duppattas. Lyrics can also be about crops and the coming of a new season. Bhangra is sung fiercely with strong lyrics often yelling: "balle balle" or "chakde phate", which refer to celebration and/or pride. + +Notable bhangra or Punjabi lyricists include Harbans Jandu who wrote "Giddhian Di Rani". + +Instruments + +Punjabi instruments contribute to bhangra. Originally this was primarily the dhol. The 20th century has brought changes to the instruments that define bhangra, to include the tumbi, sarangi, dholak (smaller than the dhol), flute, zither, fiddle, harmonium, tabla, guitar, mandolin, saxophone, synthesizer, drum set, and other Western instruments. Perhaps the most famous Bhangra instrument is the dhol. It is a double-sided barrel drum that creates the beat to which Bhangra is danced. The person who plays the instrument, the dholi, plays various beats to create the different Bhangra segments, such as Dhamaal, Jhummar, One side of the dhol has thicker skin, which creates a deeper sound, and the other side has a thinner skin, resulting in a higher-pitched sound. Two sticks are used to play the dhol instrument. The thicker stick, called the dagga, is used to play the bass side. The thinner tilli is used to play the treble side. Both sticks are usually made of wood or bamboo. + +The string instruments include the guitar (both electrical), bass, sitar, tumbi, veena, violin and sarangi. The snare, toms, dhadd, dafli, dholki, and damru are the other drums. The tumbi, originally played by folk artists such as Lalchand Yamla Jatt and Kuldip Manak in true folk recordings and then notably used by Chamkila, a Punjabi folk (not bhangra) singer, is a high-tone, single-string instrument and Chimta by (Late) Alam Lohar. + +Cultural impact and resurgence of Punjabi folk music in the West + +The third and fourth generation are generally unable to speak Punjabi if their parents could hardly speak it. There is a move towards Punjabi folk music which is the purest form of Punjabi music. Much of the youth struggle to understand the lyrics, although, there are some children and young adults who have maintained their folk roots. Another reason why some fans express an anti-folk sentiment is that many folk songs were written for the dominant Jatts clan whereas Sikhs do not believe in castes, so they disapproved of Punjabi folk music. However, today with artists like Jazzy B, PMC, Sukhshinder Shinda and Diljit Dosanjh, Punjabi folk has increased in popularity although it is fused in some cases. iTunes has catalogs of many Punjabi folk singers available. + +Another cause of the resurgence of Punjabi folk music is due to the increased popularity of bhangra in areas like the UK, Canada and U.S. Bhangra has become more accessible through social media platforms such as YouTube and Instagram, for the younger generation. In addition, multiple universities, across the UK, US and Canada have teams as well as academies being set up by senior dancers separate from universities. This resurgence has led to a desire for more traditional folk songs and beats, but also a learning opportunity for children of their cultures. + +Derivatives + +Bhangragga +Bhangragga or bhangramuffin is a term for the style of music incorporating elements of Bhangra and dancehall (or ragga, short for the word Raggamuffin) created by British Asian producers Simon and Diamond on the debut album by Apache Indian No Reservations (1993). +The sound is very percussion-heavy – a distinct holdover from Bhangra – with a propulsive beat clearly designed for dancing. The dancehall influence can be felt through the use of pre-programmed music, similar to Dancehall "riddims". +Lyrically, the style features a combination of Sub-Continental-accented (usually Indian) vocals delivered in the clipped style associated with dancehall – and sometimes including the Patois of the latter style. +This style is almost exclusively a British phenomenon, as the two cultures involved in its genesis mix reasonably freely there. The most successful exponent, however, is Apache Indian, who had a worldwide hit with "Boom Shack-A-Lak", which was included on the soundtrack to the film Dumb and Dumber, among others. + +See also +List of bhangra artists +Music of Punjab +Punjabi culture +Asian Underground +Multitone records +Dhol +Punjab region +Music of the United Kingdom + +References + +External links + +Where Bhangra Lives +Bhangra News, Music Videos & Interviews +www.Bhangra.org +House Of Bhangra + India Music – The first ever Indian Music domain and web site registered. + + +Punjabi music +Indian styles of music +Pakistani styles of music +Punjabi words and phrases +Culture of the United Kingdom +Indian diaspora in the United Kingdom +Pakistani diaspora in the United Kingdom +Dance music genres +Punjabi diaspora +Pop music genres +Beastie Boys were an American hip hop/rap rock group from New York City, formed in 1981. The group was composed of Michael "Mike D" Diamond (vocals, drums), Adam "MCA" Yauch (vocals, bass), and Adam "Ad-Rock" Horovitz (vocals, guitar, programming). Beastie Boys were formed out of members of experimental hardcore punk band The Young Aborigines, which was formed in 1979, with Diamond on drums, Jeremy Shatan on bass guitar, John Berry on guitar, and Kate Schellenbach later joining on percussion. When Shatan left New York City in the summer of 1981, Yauch replaced him on bass and the resulting band was named Beastie Boys. Berry left shortly thereafter and was replaced by Horovitz. + +After achieving local success with the 1983 comedy hip hop single "Cooky Puss", Beastie Boys made a full transition to hip hop, and Schellenbach left. They toured with Madonna in 1985 and a year later released their debut album, Licensed to Ill (1986), the first rap album to top the Billboard 200 chart. Their second album, Paul's Boutique (1989), composed almost entirely of samples, was a commercial failure that later received critical acclaim. Check Your Head (1992) and Ill Communication (1994) found mainstream success, followed by Hello Nasty (1998), To the 5 Boroughs (2004), The Mix-Up (2007), and Hot Sauce Committee Part Two (2011). + +Beastie Boys have sold 20 million records in the United States and had seven platinum-selling albums from 1986 to 2004. They are the biggest-selling rap group since Billboard began recording sales in 1991. In 2012, they became the third rap group to be inducted into the Rock and Roll Hall of Fame. In the same year, Yauch died of cancer and Beastie Boys disbanded. The remaining members have released several retrospective works, including a book, a documentary, and a career-spanning compilation album. + +History + +1979–1983: Formation and early years +Prior to forming Beastie Boys, Michael Diamond was part of a number of bands such as the Walden Jazz Band, BAN, and the Young Aborigines. Beastie Boys formed in July 1981 when the Young Aborigines bassist Jeremy Shatan left New York City for the summer and the remaining members Diamond, John Berry and Kate Schellenbach formed a new hardcore punk band with Adam Yauch. + +In a 2007 interview with Charlie Rose, Yauch recalled that it was Berry who suggested the name Beastie Boys. Although the band stated that "Beastie" is an acronym standing for "Boys Entering Anarchistic States Towards Inner Excellence", in the Charlie Rose interview, both Yauch and Diamond acknowledged that the acronym was an "afterthought" conceived after the name was chosen. The band supported Bad Brains, the Dead Kennedys, the Misfits and Reagan Youth at venues such as CBGB, A7, Trude Heller's and Max's Kansas City, playing at the latter venue on its closing night. In November 1982, Beastie Boys recorded the 7-inch EP Polly Wog Stew at 171A studios, an early recorded example of New York hardcore. + +On November 13, 1982, Beastie Boys played Philip Pucci's birthday for the purposes of his short concert film, Beastie. Pucci held the concert in Bard College's Preston Drama Dance Department Theatre. This performance marked Beastie Boys' first on screen appearance in a published motion picture. Pucci's concept for Beastie was to distribute a mixture of both a half dozen 16 mm Bell & Howell Filmo cameras, and 16 mm Bolex cameras to audience members and ask that they capture Beastie Boys performance from the audience's own point of view while a master sync sound camera filmed from the balcony of the abandoned theater where the performance was held. The opening band for that performance was the Young and the Useless, which featured Adam Horovitz as the lead singer. A one-minute clip of Beastie was subsequently excerpted and licensed by Beastie Boys for use in the "Egg Raid on Mojo" segment of the "Skills to Pay the Bills" long-form home video released by Capitol Records. "Skills to Pay the Bills" later went on to be certified Gold by the Recording Industry Association of America (RIAA). Berry left the group in 1982 (later forming Thwig, Big Fat Love and Bourbon Deluxe) and was replaced by Horovitz, who had become close friends with Beastie Boys. + +The band also recorded and then performed its first hip hop track, "Cooky Puss", based on a prank call by the group to a Carvel Ice Cream franchise in 1983. It was a part of the new lineup's first EP, also called Cooky Puss, which was the first piece of work that showed their incorporation of the underground rap phenomenon and the use of samples. It quickly became a hit in New York underground dance clubs and night clubs. After "Beastie Revolution" was later sampled in a British Airways commercial, Beastie Boys threatened to sue them over the use of the song, and the airline immediately paid them $40,000 in royalties. + +1984–1987: Def Jam years and Licensed to Ill +Following the success of "Cooky Puss", the band began to incorporate rap into their sets. They hired a DJ for their live shows, New York University student Rick Rubin, who began producing records soon thereafter. "I met Mike first," Rubin recalled. "I thought he was an arrogant asshole. Through spending time with the Beasties I grew to see that they had this great sense of humor. It wasn't that they were assholes, and even if it was, they were funny with it." Rubin formed Def Jam Recordings with fellow NYU student Russell Simmons, and approached the band about producing them for his new label. As the band was transitioning to hip hop, Schellenbach was fired in 1984, with Diamond taking over on drums. In their 2018 memoir, Ad-Rock expressed regret for firing Schellenbach, which he attributed to her not fitting with the "new tough-rapper-guy identity". + +The band's 12-inch single "Rock Hard" (1984) was the second Def Jam record crediting Rubin as producer (the first was "It's Yours" by T La Rock and Jazzy Jay). On July 22, 1986, Beastie Boys opened for John Lydon's post-Sex Pistols band Public Image Ltd., and supported Madonna on her North American The Virgin Tour. Then headlining with Fishbone and Murphy's Law with DJ Hurricane and later in the year, the group was on the Raising Hell tour with Run-DMC, Whodini, LL Cool J, and the Timex Social Club. Thanks to this exposure, "Hold It Now, Hit It" charted on Billboards US R&B and dance charts. "She's on It" from the Krush Groove soundtrack continued in a rap/metal vein while a double A-side 12", "Paul Revere/The New Style", was released at the end of the year. + +The band recorded Licensed to Ill in 1986 and released it on November 15, 1986. The album was favorably reviewed by Rolling Stone magazine. Licensed to Ill became one of the best-selling rap albums of the 1980s and the first rap album to go number 1 on the Billboard 200 chart, where it stayed for five weeks. It also reached number 2 on the Top R&B album chart. It was Def Jam's fastest selling debut record to date and sold over nine million copies. The fourth single, "(You Gotta) Fight for Your Right (To Party!)", reached number 7 on the US Billboard Hot 100. Although the group has sold over 26 million records in the US, this is their only single to peak in the US top ten or top twenty. The accompanying video (directed by Ric Menello and Adam Dubin) became an MTV staple. Another song from the album, "No Sleep till Brooklyn", peaked at number 14 on the UK Singles Chart. + +The band took the Licensed to Ill tour around the world the following year. The tour was troubled by lawsuits and arrests, with the band accused of provoking the crowd. This culminated in a notorious gig at the Royal Court Theatre, Liverpool, England, on May 30, 1987, that erupted into a riot approximately 10 minutes after the group hit the stage and the arrest of Adam Horovitz by Merseyside Police. He was charged with assault causing grievous bodily harm. + +1988–1989: Move to Capitol Records and Paul's Boutique +In 1988, Beastie Boys appeared in Tougher Than Leather, a film directed by Rubin as a star vehicle for Run-D.M.C. and Def Jam Recordings. After Def Jam stopped paying them for work they'd already done and were owed money for, Beastie Boys left Def Jam and signed with Capitol Records. + +The second Beastie Boys album, Paul's Boutique, was released on July 25, 1989. Produced by the Dust Brothers, it blends eclectic samples and has been described as an early work of experimental hip hop. It failed to match the sales of Licensed to Ill, reaching number 14 on the US album charts, but later attracted acclaim; Rolling Stone ranked it number 156 on its list of the 500 Greatest Albums of All Time. + +1990–1996: Check Your Head and Ill Communication + +Check Your Head was recorded in the band's G-Son studio in Atwater Village, California, and released on its Grand Royal record label. The band was influenced to play instruments on this album by Dutch group Urban Dance Squad; with Mike D on drums, Yauch on bass, Horovitz on guitar and Mark Ramos Nishita ("Keyboard Money Mark") on keyboards. Mario Caldato, Jr., who had helped in the production of Paul's Boutique, engineered the record and became a longtime collaborator. Check Your Head was released in 1992 and was certified double Platinum in the US and peaked at number 10 on the Billboard 200. The single "So What'cha Want" reached number 93 on the Billboard Hot 100 and charted on both the Rap and Modern Rock Chart, while the album's first single, "Pass the Mic", peaked at number 38 on the Hot Dance Music chart. The album also introduced a more experimental direction, with funk and jazz inspired songs including "Lighten Up" and "Something's Got to Give". The band returned to their hardcore punk roots for the song "Time for Livin'", a cover of a 1974 Sly and the Family Stone song. The addition of instruments and the harder rock sound of the album could be considered a precursor to the nu metal genre of music to come out in the later half of the 1990s. + +Beastie Boys signed an eclectic roster of artists to their Grand Royal label, including Luscious Jackson, Sean Lennon, and Australian artist Ben Lee. The group owned Grand Royal Records until 2001. Grand Royal's first independent release was Luscious Jackson's album In Search of Manny in 1993. Also in 1993, the band contributed the track "It's the New Style" (with DJ Hurricane) to the AIDS benefit album No Alternative, produced by the Red Hot Organization. + +Beastie Boys also published Grand Royal Magazine, with the first edition in 1993 featuring a cover story on Bruce Lee, artwork by George Clinton, and interviews with Kareem Abdul-Jabbar and A Tribe Called Quest's MC Q-Tip. The 1995 issue of the magazine contained a memorable piece on the mullet. The Oxford English Dictionary cites this as the first published use of the term, along with the lyrics from the band's 1994 song, "Mullet Head". That term was not heard in the 1980s, even though that decade has retroactively been hailed as the mullet's peak in popularity. The OED says that the term was "apparently coined, and certainly popularized, by US hip-hop group Beastie Boys". Grand Royal Magazine is also responsible for giving British band Sneaker Pimps their name. + +Ill Communication, released in 1994, saw Beastie Boys' return to the top of the charts when the album debuted at number 1 on the Billboard 200 and peaked at number 2 on the R&B/hip hop album chart. The single "Sabotage" became a hit on the modern rock charts and the music video, directed by Spike Jonze, received extensive play on MTV. "Get It Together" reached the top 10 on the Billboard Hot 100. Also in 1994, the band released Some Old Bullshit, featuring the band's early independent material, which made it to number 46 on the Billboard Independent Albums chart. + +Beastie Boys headlined at Lollapalooza—an American travelling music festival—in 1994, together with The Smashing Pumpkins. In addition, the band performed three concerts (in Los Angeles, New York City, and Washington, D.C.) to raise money for the Milarepa Fund and dedicated the royalties from "Shambala" and "Bodhisattva Vow" from the Ill Communication to the cause. The Milarepa Fund aims to raise awareness of Tibetan human rights issues and the exile of the Dalai Lama. In 1996, Yauch organized the largest rock benefit show since 1985's Live Aid – the Tibetan Freedom Concert, a two-day festival at Golden Gate Park in San Francisco that attracted over 100,000 attendees. + +In 1995, the popularity of Beastie Boys was underlined when tickets for an arena tour went on sale in the US and Madison Square Garden and Chicago's Rosemont Horizon sold out within 30 minutes. One dollar from each ticket sold went through Milarepa to local charities in each city on the tour. Beastie Boys toured South America and Southeast Asia for the first time. The band also released Aglio e Olio, a collection of eight songs lasting just 11 minutes harking back to their punk roots, in 1995. The In Sound from Way Out!, a collection of previously released jazz/funk instrumentals, was released on Grand Royal in 1996 with the title and artwork a homage to an album by electronic pop music pioneers Perrey and Kingsley. + +In 1992, Beastie Boys decided to sample portions of the sound recording of "Choir" by James Newton in various renditions of their song "Pass the Mic". The band did not obtain a license from Newton to use the composition. Pursuant to their license from ECM Records, Beastie Boys digitally sampled the opening six seconds of Newton's sound recording of "Choir", and repeated this six-second sample as a background element throughout their song. Newton brought suit, claiming that the band infringed his copyright in the underlying composition of "Choir". The district court granted Beastie Boys summary judgment. The district court said that no license was required because the three-note segment of "Choir" lacked the requisite originality and was therefore not copyrightable. The decision was affirmed on appeal. + +1997–2001: Hello Nasty + +Beastie Boys began work on the album Hello Nasty at the G-Son studios, Los Angeles in 1995, but continued to produce and record it in New York City after Yauch moved to Manhattan in 1996. The album displayed a substantial shift in musical feel, with the addition of Mix Master Mike. The album featured bombastic beats, rap samples, and experimental sounds. Released on July 14, 1998, Hello Nasty earned first week sales of 681,000 in the US and went straight to number 1 in the US, the UK, Germany, Australia, the Netherlands, New Zealand, and Sweden. The album achieved number 2 rank on the charts in Canada and Japan, and reached top-ten chart positions in Austria, Switzerland, Ireland, Belgium, Finland, France and Israel. + +Beastie Boys won two Grammy Awards in 1999, receiving the Grammy Award for Best Alternative Music Album for Hello Nasty as well as the Grammy Award for Best Rap Performance by a Duo or Group for "Intergalactic". This was the first and, as of 2008, only time that a band had won awards in both rap and alternative categories. + +Also at the 1998 MTV Video Music Awards they won the Michael Jackson Video Vanguard Award for their contribution to music videos. The following year at the 1999 MTV Video Music Awards they also won the award for Best Hip Hop Video for their hit song "Intergalactic". Beastie Boys used both appearances at the Video Music Awards to make politically charged speeches of considerable length to the sizable MTV audiences. At the 1998 ceremony, Yauch addressed the issue of Muslim people being stereotyped as terrorists and that most people of the Muslim faith are not terrorists. These comments were made in the wake of the US Embassy bombings that had occurred in both Kenya and Tanzania only a month earlier. At the 1999 ceremony in the wake of the horror stories that were coming out of Woodstock 99, Adam Horovitz addressed the fact that there had been many cases of sexual assaults and rapes at the festival, suggesting the need for bands and festivals to pay much more attention to the security details at their concerts. + +Beastie Boys started an arena tour in 1998. Through Ian C. Rogers, the band made live downloads of their performances available for their fans, but were temporarily thwarted when Capitol Records removed them from its website. Beastie Boys was one of the first bands who made MP3 downloads available on their website. The group got a high level of response and public awareness as a result including a published article in The Wall Street Journal on the band's efforts. + +On September 28, 1999, Beastie Boys joined Elvis Costello to play "Radio Radio" on the 25th anniversary season of Saturday Night Live. + +Beastie Boys released The Sounds of Science, a two-CD anthology of their works in 1999. This album reached number  19 on the Billboard 200, number 18 in Canada, and number 14 on the R&B/Hip Hop chart. The one new song, the single "Alive", reached number 11 on the Billboard Modern Rock chart. + +In 2000, Beastie Boys had planned to co-headline the "Rhyme and Reason Tour" with Rage Against the Machine and Busta Rhymes, but the tour was canceled when drummer Mike D sustained a serious injury due to a bicycle accident. The official diagnosis was fifth-degree acromioclavicular joint dislocation; he needed surgery and extensive rehabilitation. By the time he recovered, Rage Against the Machine had disbanded, although they would reunite seven years later. + +Under the name Country Mike, Mike D recorded an album, Country Mike's Greatest Hits, and gave it to friends and family for Christmas in 2000. Adam "Ad-Rock" Horovitz's side project BS 2000 released Simply Mortified in 2001. + +In October 2001, after the September 11, 2001 attacks, Beastie Boys organized and headlined the New Yorkers Against Violence Concert at the Hammerstein Ballroom. + +2002–2008: To the 5 Boroughs and The Mix-Up + +In 2002, Adam Yauch started building a new studio facility, Oscilloscope Laboratories, in downtown Manhattan, New York and the band started work on a new album there. The band released a protest song, "In a World Gone Mad", against the 2003 Iraq war as a free download on several websites, including the Milarepa website, the MTV website, MoveOn.org, and Win Without War. The 19th and 20th Tibetan Freedom Concerts were held in Tokyo and Taipei, Beastie Boys' first Taiwan appearance. Beastie Boys also headlined the Coachella Valley Music and Arts Festival. + +Their single, "Ch-Check It Out", debuted on The O.C. in "The Vegas" episode from Season 1, which aired April 28, 2004. + +To the 5 Boroughs was released worldwide on June 15, 2004. It was the first album the band produced themselves and reached number 1 on the Billboard albums chart, number 2 in the UK and Australia, and number 3 in Germany. The first single from the album, "Ch-Check It Out", reached number 1 in Canada and on the US Modern Rock Tracks chart. + +The album was the cause of some controversy with allegations that it installed spyware when inserted into the CD drive of a computer. The band denied this allegation, defending that there is no copy protection software on the albums sold in the US and UK. While there is Macrovision CDS-200 copy protection software installed on European copies of the album, this is standard practice for all European releases on EMI/Capitol Records released in Europe, and it does not install spyware or any form of permanent software. + +The band stated in mid-2006 that they were writing material for their next album and would be producing it themselves. + +Speaking to British music weekly NME (April 26, 2007), Diamond revealed that a new album was to be called The Mix-Up. Despite initial confusion regarding whether the album would have lyrics as opposed to being purely instrumental, the Mic-To-Mic blog reported that Capitol Records had confirmed it would be strictly instrumental and erroneously reported a release date scheduled for July 10, 2007. (The album was eventually released June 26, as originally reported.) On May 1, 2007, this was further cemented by an e-mail sent to those on the band's mailing list – explicitly stating that the album would be all instrumental: + +The band subsequently confirmed the new album and announced a short tour that focused on festivals as opposed to a traditional tour, including the likes of Sónar (Spain), Roskilde (Denmark), Hurricane/Southside (Germany), Bestival (Isle of Wight), Electric Picnic (Ireland) and Open'er Festival (Poland). Beastie Boys performed at the UK leg of Live Earth July 7, 2007 at Wembley Stadium, London with "Sabotage", "So What'cha Want", "Intergalactic", and "Sure Shot". + +They worked with Reverb, a non-profit environmental organization, on their 2007 summer tour, and headlined the Langerado Music Festival in South Florida on Friday, March 7, 2008. The band won a Grammy for The Mix-Up in the "Best Pop Instrumental Album" category at the 50th Annual Grammy Awards in 2008. + +2009–2012: Hot Sauce Committee + +In February 2009, Yauch revealed their forthcoming new album had taken the band's sound in a "bizarre" new direction, saying "It's a combination of playing and sampling stuff as we're playing, and also sampling pretty obscure records." The tentative title for the record was Tadlock's Glasses, of which Yauch explained the inspiration behind the title: + +On May 25, 2009, it was announced during an interview on Late Night with Jimmy Fallon that the name of their new album would be Hot Sauce Committee and was set for release on September 15 (with the track listing of the album announced through their mailing list on June 23). The album included a collaboration with Santigold who co-wrote and sang with the band on the track "Don't Play No Game That I Can't Win". + +In June, the group appeared at Bonnaroo Music and Arts Festival and performed the new single from the album titled "Too Many Rappers" alongside rapper Nas who appears on the track. It would be the last live performance by Beastie Boys as a trio. The group would have toured the UK later in the year in support of the new record. + +Speaking to Drowned in Sound, Beastie Boys revealed that Part 2 was done. Mike D also hinted it may be released via unusual means: + +On July 20, Yauch announced on the band's official YouTube channel and through the fan mailing list, the cancellation of several tour dates and the postponement of the new album due to the discovery of a cancerous tumor in his parotid gland and a lymph node. The group also had to cancel their co-headlining gig at the Osheaga Festival in Montreal and also another headlining spot for the first night of the All Points West Festival in Jersey City, New Jersey. + +In late October 2010, Beastie Boys sent out two emails regarding the status of Hot Sauce Committee Pts. 1 and 2 to their online mailing list. An email dated October 18 read: "Although we regret to inform you that Hot Sauce Committee Part 1 will continue to be delayed indefinitely, Hot Sauce Committee Part 2 will be released on time as originally planned in spring of 2011." One week later, a second email was sent out, reading as follows: + +The official release dates were April 27, 2011, for Japan; April 29 in the UK and Europe, and May 3, 2011, in the US. The third single for the album "Make Some Noise" was made available for download on April 11, 2011, as well as a limited edition 7-inch vinyl single for Record Store Day five days later with a Passion Pit remix of the track as a b-side. The track was leaked online on April 6 and subsequently made available via their blog. + +On April 22, Beastie Boys emailed out the cryptic message "This Sat, 10:35 am EST – Just listen, listen, listen to the beat box". A day later, they live streamed their album online via beatbox inside Madison Square Garden. + +The band was announced as an inductee into the Rock and Roll Hall of Fame in December 2011. They were inducted by Chuck D and LL Cool J on April 14, 2012. Yauch was too sick to attend the ceremony, having been admitted to NewYork–Presbyterian Hospital the same day, therefore the group didn't perform; instead Black Thought, Travie from Gym Class Heroes and Kid Rock performed a medley of their songs. Diamond and Horovitz accepted and read a letter that Yauch had written. + +2012–present: Deaths of Yauch and Berry, and disbandment +On May 4, 2012, Yauch died from cancer at the age of 47. Mike D told Rolling Stone that Beastie Boys had recorded new music in late 2011, but did not say if these recordings would be released. He also said that Beastie Boys would likely disband due to the death of MCA, though he was open to making new music with Ad-Rock and that "Yauch would genuinely want us to try whatever crazy thing we wanted but never got around to". In June 2014, Mike D confirmed that he and Ad-Rock would not make music under the Beastie Boys name again. + +Founding Beastie Boys guitarist John Berry died on May 19, 2016, aged 52, as a result of frontotemporal dementia, following several years of ill health. He was credited with naming the band Beastie Boys and played guitar on the first EP. The first Beastie Boys show took place at Berry's loft. + +Yauch's will forbids the use of Beastie Boys music in advertisements. In June 2014, Beastie Boys won a lawsuit against Monster Energy for using their music in a commercial without permission. They were awarded $1.7 million in damages and $668,000 for legal fees. + +In October 2018, Mike D and Ad-Rock released a memoir, Beastie Boys Book, recounting events throughout the group's history. The book was adapted into a documentary in April 2020, titled Beastie Boys Story, directed by Spike Jonze and premiered on Apple TV+. The book and documentary were also complemented by the compilation album Beastie Boys Music, released in October 2020. + +Tibetan Freedom Concert + +In 1994, Yauch and activist Erin Potts organized the Tibetan Freedom Concert in order to raise awareness of humans rights abuses by the Chinese government on the Tibetan people. Yauch became aware of this after hiking in Nepal and speaking with Tibetan refugees. The events became annual, and shortly after went international with acts such as Live, Mike Mills and Michael Stipe of R.E.M., Rage Against the Machine, The Smashing Pumpkins, and U2. + +Musical style, influences, and legacy +Originally a hardcore punk band, Beastie Boys had largely abandoned the genre in favor of hip hop and rap rock by the time work began on their debut studio album Licensed to Ill. The group mixed elements of hip hop, punk, funk, electro, jazz and Latin music into their music. They have also been described as alternative hip hop, and punk rap. + +Around the time of the release of their debut album, Licensed to Ill, Mike D started to appear on stage and in publicity photographs wearing a large Volkswagen emblem attached to a chain-link necklace. This started a rash of thefts of the emblem from vehicles around the world as fans tried to emulate him. A controversial concert in Columbus, Georgia in 1987 led to the passage of a lewdness ordinance in that city. + +Beastie Boys are considered very influential in both the hip hop and rock music scenes, with artists such as Eminem, Rage Against the Machine, Hed PE, , Sublime, and Blur citing them as an influence. Beastie Boys have had four albums reach the top of the Billboard album charts (Licensed to Ill, Ill Communication, Hello Nasty and To the 5 Boroughs) since 1986. In the November 2004 issue, Rolling Stone named "Sabotage" the 475th song on their 500 Greatest Songs of All Time list. +In their April 2005 issue, Rolling Stone ranked them number 77 on their list of the 100 Greatest Artists of All Time. VH1 ranked them number 89 on their list of their 100 Greatest Artists of All Time. On September 27, 2007, it was announced that Beastie Boys were one of the nine nominees for the 2008 Rock and Roll Hall of Fame Inductions. In December 2011, they were announced to be official 2012 inductees. + +Beastie Boys have many high-profile longtime fans, including Ultimate Fighting Championship (UFC) president Dana White, who has a hand-signed bass guitar signed by all three members in his office and a copy of the Beastie Boys book. Speaking on the death of Adam Yauch, White said, "I seriously haven't been impacted by a death in a long time like I was with the Beastie Boys". Actor Seth Rogen, who appeared in the video for "Make Some Noise", also said, "I'm a huge Beastie Boys fan and they just called and asked if I wanted to be a part of it, and I said yes without hesitation. I didn't need to hear anything. I didn't need to see anything, any concepts. I was just like, 'I will literally do anything you ask me to do". Ben Stiller was seen in the crowd for the DVD release Awesome; I Fuckin' Shot That! and featured Horovitz in his movie While We're Young, where he said, "I'm a huge Beastie Boys fan, so doing that, for me, was beyond anything". Eminem was highly influenced by the Beastie Boys and cited them alongside LL Cool J as being the reason he got into rap. During an interview with MTV after the death of Yauch, he said, "Adam Yauch brought a lot of positivity into the world and I think it's obvious to anyone how big of an influence the Beastie Boys were on me and so many others. They are trailblazers and pioneers and Adam will be sorely missed. My thoughts and prayers are with his family, Mike D., and Ad-Rock." His album cover for Kamikaze paid homage to Licensed to Ill and he also paid homage in his "Berzerk" video. In an interview with Rolling Stone, Beavis and Butt-Head creator Mike Judge acknowledged he was a fan of the band, citing his favorite song as "Fight for Your Right", as the Beastie Boys appeared on Beavis and Butt-Head on numerous occasions. Kid Rock wrote an in-depth tribute to Yauch after being influenced by the band, which said, "I thought I was the 4th member of Beastie Boys in 7th grade. You couldn't tell me I wasn't. The first time I ever saw them on stage was a very early show of theirs before Licensed to Ill came out, opening for Run DMC at Joe Louis Arena. My jaw dropped to the floor!" + +In 2020, Spin Magazine ranked Beastie Boys as the 12th most influential artist of the previous 35 years. + +In 2022, the New York City Council voted to rename the intersection of Ludlow and Rivington streets in Manhattan’s Lower East Side - the location of the Paul’s Boutique album cover - “Beastie Boys Square”. The vote was result of a grassroots campaign started in 2013 by historian LeRoy McCarthy. The proposed renaming was voted down when first proposed in 2014, but was accepted on July 14, 2022. The square was renamed on September 9, 2023, coinciding with the 50th anniversary of hip hop. + +Sampling lawsuit + +In 2003, Beastie Boys were involved in the landmark sampling decision Newton v. Diamond. In that case, a federal judge ruled that the band was not liable for sampling James Newton's "Choir" in their track "Pass the Mic". The sample used is the six-second flute stab. In short, Beastie Boys cleared the sample but obtained only the rights to use the sound recording and not the composition rights to the song "Choir". In the decision, the judge found that: + +Members + +Members + John Berry – guitars (1981–1982; died 2016) + Mike D – vocals, drums (1981–2012) + Kate Schellenbach – drums, percussion (1981–1984) + MCA – vocals, bass (1981–2012; died 2012) + Ad-Rock – vocals, guitars (1982–2012) + +Touring musicians + DJ Double R (Rick Rubin) – disc jockey (1984–1985) + Doctor Dré – disc jockey (1986) + DJ Hurricane – disc jockey (1986–1997) + Eric Bobo – percussion, drums (1992–1996) + Money Mark (Mark Ramos-Nishita) – keyboards, vocals (1992–2012) + Amery "AWOL" Smith – drums, backing vocals, percussion (1992–1998) + Alfredo Ortiz – drums, percussion (1996–2012) + Mix Master Mike – disc jockey, backing vocals (1998–2012) + +Timeline + +Discography + +Studio albums + Licensed to Ill (1986) + Paul's Boutique (1989) + Check Your Head (1992) + Ill Communication (1994) + Hello Nasty (1998) + To the 5 Boroughs (2004) + The Mix-Up (2007) + Hot Sauce Committee Part Two (2011) + +Tours + The Virgin Tour (1985) (supporting Madonna) + Raising Hell Tour (1986) (supporting Run-D.M.C.) + Licensed to Ill Tour (1987) (with Public Enemy) + Together Forever Tour (1987) (with Run-D.M.C.) + Check Your Head Tour (1992) (with Cypress Hill, Rollins Band, Firehose, and Basehead) + Lollapolooza (1994) + Ill Communication Tour (1994–1995) + In the Round Tour (1998–1999) (with A Tribe Called Quest and Money Mark) + To the 5 Boroughs Tour (2004) + The Mix-Up Tour (2007–2008) + +Awards and nominations +Grammy Awards + +|- +|1992 +|Check Your Head +|Best Rap Performance by a Duo or Group +| +|- +|1995 +|"Sabotage" +|Best Hard Rock Performance +| +|- +|Rowspan="2"|1999 +|"Intergalactic" +|Best Rap Performance by a Duo or Group +| +|- +|Hello Nasty +|Best Alternative Music Album +| +|- +|2001 +|"Alive" +|Best Rap Performance by a Duo or Group +| +|- +|rowspan="2"|2005 +|"Ch-Check It Out" +|Best Rap Performance by a Duo or Group +| +|- +|To The 5 Boroughs +|Best Rap Album +| +|- +|rowspan="2"|2008 +|"Off the Grid" +|Best Pop Instrumental Performance +| +|- +|The Mix-Up +|Best Contemporary Instrumental Album +| +|- +|2010 +|"Too Many Rappers" (featuring Nas) +|Best Rap Performance by a Duo or Group +| +|} + +MTV Video Music Awards + +|- +|rowspan="5"|1994 +|rowspan="5"|"Sabotage" +|Video of the Year +| +|- +|Best Group Video +| +|- +|Breakthrough Video +| +|- +|Best Direction (Director: Spike Jonze) +| +|- +|Viewer's Choice +| +|- +|1998 +|Beastie Boys +|Michael Jackson Video Vanguard Award +| +|- +|1999 +|"Intergalactic" +|Best Hip-Hop Video +| +|- +|2009 +|"Sabotage" +|Best Video (That Should Have Won a Moonman) +| +|- +|rowspan="2"|2011 +|rowspan="2"|"Make Some Noise" +|Video of the Year +| +|- +|Best Direction (Director: Adam Yauch) +| +|} + +MTV Europe Music Awards + +|- +|1994 +|Beastie Boys +|Best Group +| +|- +|rowspan="4"|1998 +|"Intergalactic" +|Best Video +| +|- +|Hello Nasty +|Best Album +| +|- +|rowspan="2"|Beastie Boys +|Best Group +| +|- +|Best Hip-Hop +| +|- +|1999 +|Beastie Boys +|Best Hip-Hop +| +|- +|rowspan="2"|2004 +|rowspan="2"|Beastie Boys +|Best Group +| +|- +|Best Hip-Hop +| +|- +|2011 +|"Make Some Noise" +|Best Video +| +|} + +MTV Video Music Awards Japan + +|- +|2005 +|"Ch-Check It Out" +|Best Hip-Hop Video +| +|- +|2009 +|Beastie Boys +|MTV Street Icon Award +| +|} + +Filmography + Krush Groove (1985) + Tougher Than Leather (1988) + Futurama episode "Hell Is Other Robots" (1999) + Awesome; I Fuckin' Shot That!

They have a total area of and a combined population of almost 72 million, and include two sovereign states, the Republic of Ireland (which covers roughly five-sixths of Ireland), and the United Kingdom of Great Britain and Northern Ireland. The Channel Islands, off the north coast of France, are normally taken to be part of the British Isles, even though they do not form part of the archipelago. + +The oldest rocks are 2.7 billion years old and are found in Ireland, Wales and the northwest of Scotland. During the Silurian period, the north-western regions collided with the south-east, which had been part of a separate continental landmass. The topography of the islands is modest in scale by global standards. Ben Nevis, the highest mountain, rises to only , and Lough Neagh, which is notably larger than other lakes in the island group, covers . The climate is temperate marine, with cool winters and warm summers. The North Atlantic drift brings significant moisture and raises temperatures above the global average for the latitude. This led to a landscape that was long dominated by temperate rainforest, although human activity has since cleared the vast majority of forest cover. The region was re-inhabited after the last glacial period of Quaternary glaciation, by 12,000 BC, when Great Britain was still part of a peninsula of the European continent. Ireland may have been connected to Great Britain by way of an ice bridge before 14,000 BC, and was not inhabited until after 8000 BC. Great Britain became an island by 7000 BC with the flooding of Doggerland. + +The Hiberni (Ireland), Picts (northern Great Britain) and Britons (southern Great Britain), all speaking Insular Celtic languages, inhabited the islands at the beginning of the 1st millennium BC. Much of Brittonic-occupied Britain was conquered by the Roman Empire from AD 43. The first Anglo-Saxons arrived as Roman power waned in the 5th century, and eventually they dominated the bulk of what is now England. Viking invasions began in the 9th century, followed by more permanent settlements and political change, particularly in England. The Norman conquest of England in 1066 and the later Angevin partial conquest of Ireland from 1169 led to the imposition of a new Norman ruling elite across much of Britain and parts of Ireland. By the Late Middle Ages, Great Britain was separated into the Kingdom of England and Kingdom of Scotland, while control in Ireland fluxed between Gaelic kingdoms, Hiberno-Norman lords and the English-dominated Lordship of Ireland, soon restricted only to The Pale. The 1603 Union of the Crowns, Acts of Union 1707 and Acts of Union 1800 aimed to consolidate Great Britain and Ireland into a single political unit, the United Kingdom of Great Britain and Ireland, with the Isle of Man and the Channel Islands remaining as Crown Dependencies. The expansion of the British Empire and migrations following the Irish Famine and Highland Clearances resulted in the dispersal of some of the islands' population and culture throughout the world, and rapid depopulation of Ireland in the second half of the 19th century. Most of Ireland seceded from the United Kingdom after the Irish War of Independence and the subsequent Anglo-Irish Treaty (1919–1922), with six counties remaining in the UK as Northern Ireland. + +As a term, "British Isles" is a geographical name and not a political unit. In Ireland, the term is controversial, and there are objections to its usage. The Government of Ireland does not officially recognise the term, and its embassy in London discourages its use. "Britain and Ireland" is used as an alternative description, and "Atlantic Archipelago" has also seen limited use in academia. In official documents created jointly by Ireland and the United Kingdom, such as the Good Friday Agreement, the term "these islands" is used. + +Etymology + +The earliest known references to the islands as a group appeared in the writings of seafarers from the ancient Greek colony of Massalia. The original records have been lost; however, later writings, e.g. Avienius's Ora maritima, that quoted from the Massaliote Periplus (6th century BC) and from Pytheas's On the Ocean (around 325–320 BC) have survived. In the 1st century BC, Diodorus Siculus has Prettanikē nēsos, "the British Island", and Prettanoi, "the Britons". Strabo used Βρεττανική (Brettanike), and Marcian of Heraclea, in his Periplus maris exteri, used αἱ Πρεττανικαί νῆσοι (the Prettanic Isles) to refer to the islands. Historians today, though not in absolute agreement, largely agree that these Greek and Latin names were probably drawn from native Celtic-language names for the archipelago. Along these lines, the inhabitants of the islands were called the Πρεττανοί (Priteni or Pretani). The shift from the "P" of Pretannia to the "B" of Britannia by the Romans occurred during the time of Julius Caesar. + +Greco-Egyptian Claudius Ptolemy referred to the larger island as great Britain (μεγάλη Βρεττανία megale Brettania) and to Ireland as little Britain (μικρὰ Βρεττανία mikra Brettania) in his work Almagest (147–148 AD). In his later work, Geography (), he gave these islands the names Alwion, Iwernia, and Mona (the Isle of Man), suggesting these may have been names of the individual islands not known to him at the time of writing Almagest. The name Albion appears to have fallen out of use sometime after the Roman conquest of Great Britain, after which Britain became the more commonplace name for the island called Great Britain in the English language. However, the cognate 'alba' has given its name to Scotland in most Celtic languages : Alba in Scottish Gaelic, Albey in Manx, Albain in Irish and Alban in Cornish and Welsh. + +The earliest known use of the phrase Brytish Iles in the English language is dated 1577 in a work by John Dee. Today, this name is seen by some as carrying imperialist overtones although it is still commonly used. Other names used to describe the islands include the Anglo-Celtic Isles, Atlantic archipelago (a term coined by the historian J. G. A. Pocock in 1975), British-Irish Isles,Britain and Ireland, UK and Ireland, and British Isles and Ireland. Owing to political and national associations with the word British, the Government of Ireland does not use the term British Isles and in documents drawn up jointly between the British and Irish governments, the archipelago is referred to simply as "these islands". British Isles is still the most widely accepted term for the archipelago. + +Geography + +The British Isles lie at the juncture of several regions with past episodes of tectonic mountain building. These orogenic belts form a complex geology that records a huge and varied span of Earth's history. Of particular note was the Caledonian orogeny during the Ordovician and early Silurian periods, when the craton Baltica collided with the terrane Avalonia to form the mountains and hills in northern Britain and Ireland. Baltica formed roughly the northwestern half of Ireland and Scotland. Further collisions caused the Variscan orogeny in the Devonian and Carboniferous periods, forming the hills of Munster, southwest England, and southern Wales. Over the last 500 million years the land that forms the islands has drifted northwest from around 30°S, crossing the equator around 370 million years ago to reach its present northern latitude. + +The islands have been shaped by numerous glaciations during the Quaternary Period, the most recent being the Devensian. As this ended, the central Irish Sea was deglaciated and the English Channel flooded, with sea levels rising to current levels some 8,000 years ago, leaving the British Isles in their current form. + +There are about 136 permanently inhabited islands in the group, the largest two being Great Britain and Ireland. Great Britain is to the east and covers . Ireland is to the west and covers . The largest of the other islands are to be found in the Hebrides, Orkney and Shetland to the north, Anglesey and the Isle of Man between Great Britain and Ireland, and the Channel Islands near the coast of France. The most densely populated island is Portsea Island, which has an area of but has the third highest population behind Great Britain and Ireland. + +The islands are at relatively low altitudes, with central Ireland and southern Great Britain particularly low-lying: the lowest point in the islands is the North Slob in County Wexford, Ireland, with an elevation of . The Scottish Highlands in the northern part of Great Britain are mountainous, with Ben Nevis being the highest point on the islands at . Other mountainous areas include Wales and parts of Ireland, although only seven peaks in these areas reach above . Lakes on the islands are generally not large, although Lough Neagh in Northern Ireland is an exception, covering . The largest freshwater body in Great Britain (by area) is Loch Lomond at , and Loch Ness (by volume) whilst Loch Morar is the deepest freshwater body in the British Isles, with a maximum depth of . There are a number of major rivers within the British Isles. The longest is the Shannon in Ireland at . The river Severn at is the longest in Great Britain. + +Climate +The climate of the British Isles is mild, moist and changeable with abundant rainfall and a lack of temperature extremes. It is defined as a temperate oceanic climate, or Cfb on the Köppen climate classification system, a classification it shares with most of northwest Europe. The North Atlantic Drift ("Gulf Stream"), which flows from the Gulf of Mexico, brings with it significant moisture and raises temperatures above the global average for the islands' latitudes. Most Atlantic depressions pass to the north of the islands; combined with the general westerly circulation and interactions with the landmass, this imposes a general east–west variation in climate. There are four distinct climate patterns: south-east, with cold winters, warm and dry summers; south-west, having mild and very wet winters, warm and wet summers; north-west, generally wet with mild winters and cool summers; and north-east with cold winters, cool summers. + +Flora and fauna + +The islands enjoy a mild climate and varied soils, giving rise to a diverse pattern of vegetation. Animal and plant life is similar to that of the northwestern European mainland. There are however, fewer numbers of species, with Ireland having even less. All native flora and fauna in Ireland is made up of species that migrated primarily from Great Britain. The only window when this could have occurred was prior to the melting of the ice bridge between the two islands 14,000 years ago approaching the end of the last ice age. + +As with most of Europe, prehistoric Britain and Ireland were covered with forest and swamp. Clearing began around 6000 BC and accelerated in medieval times. Despite this, Britain retained its primeval forests longer than most of Europe due to a small population and later development of trade and industry, and wood shortages were not a problem until the 17th century. By the 18th century, most of Britain's forests were consumed for shipbuilding or manufacturing charcoal and the nation was forced to import lumber from Scandinavia, North America, and the Baltic. Most forest land in Ireland is maintained by state forestation programmes. Almost all land outside urban areas is farmland. However, relatively large areas of forest remain in east and north Scotland and in southeast England. Oak, elm, ash and beech are amongst the most common trees in England. In Scotland, pine and birch are most common. Natural forests in Ireland are mainly oak, ash, wych elm, birch and pine. Beech and lime, though not native to Ireland, are also common there. Farmland hosts a variety of semi-natural vegetation of grasses and flowering plants. Woods, hedgerows, mountain slopes and marshes host heather, wild grasses, gorse and bracken. + +Many larger animals, such as wolves, bears and European elk are today extinct. However, some species such as red deer are protected. Other small mammals, such as rabbits, foxes, badgers, hares, hedgehogs, and stoats, are very common and the European beaver has been reintroduced in parts of Scotland. Wild boar have also been reintroduced to parts of southern England, following escapes from boar farms and illegal releases. Many rivers contain otters and grey and common seals are numerous on coasts. There are about 250 bird species regularly recorded in Great Britain, and another 350 that occur with varying degrees of rarity. The most numerous species are wren, robin, house sparrow, woodpigeon, chaffinch and blackbird. Farmland birds are declining in number, except for those kept for game such as pheasant, red-legged partridge, and red grouse. Fish are abundant in the rivers and lakes, in particular salmon, trout, perch and pike. Sea fish include dogfish, cod, sole, pollock and bass, as well as mussels, crab and oysters along the coast. There are more than 21,000 species of insects. + +Few species of reptiles or amphibians are found in Great Britain or Ireland. Only three snakes are native to Great Britain: the adder, the barred grass snake and the smooth snake; none are native to Ireland. In general, Great Britain has slightly more variation and native wildlife, with weasels, polecats, wildcats, most shrews, moles, water voles, roe deer and common toads also being absent from Ireland. This pattern is also true for birds and insects. Notable exceptions include the Kerry slug and certain species of woodlouse native to Ireland but not Great Britain. + +Domestic animals include the Connemara pony, Shetland pony, English Mastiff, Irish wolfhound and many varieties of cattle and sheep. + +Demographics + +England has a generally high population density, with almost 80% of the total population of the islands. Elsewhere in Great Britain and Ireland, high density of population is limited to areas around a few large cities. The largest urban area by far is the Greater London Built-up Area with 9 million inhabitants. Other major population centres include the Greater Manchester Built-up Area (2.4 million), West Midlands conurbation (2.4 million) and West Yorkshire Urban Area (1.6 million) in England, Greater Glasgow (1.2 million) in Scotland and Greater Dublin Area (1.9 million) in Ireland. + +The population of England rose rapidly during the 19th and 20th centuries, whereas the populations of Scotland and Wales showed little increase during the 20th century; the population of Scotland has remained unchanged since 1951. Ireland for most of its history had much the same population density as Great Britain (about one-third of the total population). However, since the Great Irish Famine, the population of Ireland has fallen to less than one-tenth of the population of the British Isles. The famine caused a century-long population decline, drastically reduced the Irish population and permanently altered the demographic make-up of the British Isles. On a global scale, this disaster led to the creation of an Irish diaspora that numbers fifteen times the current population of the island. + +The linguistic heritage of the British Isles is rich, with twelve languages from six groups across four branches of the Indo-European family. The Insular Celtic languages of the Goidelic sub-group (Irish, Manx and Scottish Gaelic) and the Brittonic sub-group (Cornish, Welsh and Breton, spoken in north-western France) are the only remaining Celtic languages—the last of their continental relations were extinct before the 7th century. The Norman languages of Guernésiais, Jèrriais and Sercquiais spoken in the Channel Islands are similar to French, a language also spoken there. A cant, called Shelta, is spoken by Irish Travellers, often to conceal meaning from those outside the group. However, English, including Scots, is the dominant language, with few monoglots remaining in the other languages of the region. The Norn language of Orkney and Shetland became extinct around 1880. + +Urban areas + +History + +2.5 million years ago the British Isles were repeatedly submerged beneath an ice sheet which extended into the middle of the North Sea, with a larger ice sheet that covered a significant proportion of Scandinavia on the opposite side. Around 1.9 million years ago these two ice sheets frequently merged, essentially creating a land bridge between Scandinavia and northern Great Britain. Further south, there was a direct land bridge, now known as Doggerland, which was gradually submerged as sea levels rose. However, the Irish Sea was formed before Doggerland was completely covered in water, with Ireland becoming an island roughly 6,000 years before Great Britain did. + +The first evidence of human activity on the islands dates from 840,000 or 950,000 years ago, based in flint tools found near Happisburgh on the Norfolk coast of Great Britain. In contrast, the earliest evidence of human activity on the island of Ireland dates from 12,500 years ago. + +At the time of the Roman Empire, about two thousand years ago, various tribes, which spoke Celtic dialects of the Insular Celtic group, were inhabiting the islands. The Romans expanded their civilisation to control southern Great Britain but were impeded in advancing any further, building Hadrian's Wall to mark the northern frontier of their empire in 122 AD. At that time, Ireland was populated by a people known as Hiberni, the northern third or so of Great Britain by a people known as Picts and the southern two thirds by Britons. + +Anglo-Saxons arrived as Roman power waned in the 5th century AD. Initially, their arrival seems to have been at the invitation of the Britons as mercenaries to repulse incursions by the Hiberni and Picts. In time, Anglo-Saxon demands on the British became so great that they came to culturally dominate the bulk of southern Great Britain, though recent genetic evidence suggests Britons still formed the bulk of the population. This dominance created what is now England and left culturally British enclaves only in the north of what is now England, in Cornwall and what is now known as Wales. Ireland had been unaffected by the Romans except, significantly, for being Christianised—traditionally by the Romano-Briton, Saint Patrick. As Europe, including Britain, descended into turmoil following the collapse of Roman civilisation, an era known as the Dark Ages, Ireland entered a golden age and responded with missions (first to Great Britain and then to the continent), the founding of monasteries and universities. These were later joined by Anglo-Saxon missions of a similar nature. + +Viking invasions began in the 9th century, followed by more permanent settlements, particularly along the east coast of Ireland, the west coast of modern-day Scotland and the Isle of Man. Though the Vikings were eventually neutralised in Ireland, their influence remained in the cities of Dublin, Cork, Limerick, Waterford and Wexford. England, however, was slowly conquered around the turn of the first millennium AD, and eventually became a feudal possession of Denmark. The relations between the descendants of Vikings in England and counterparts in Normandy, in northern France, lay at the heart of a series of events that led to the Norman conquest of England in 1066. The remnants of the Duchy of Normandy, which conquered England, remain associated to the English Crown as the Channel Islands to this day. A century later, the marriage of the future Henry II of England to Eleanor of Aquitaine created the Angevin Empire, partially under the French Crown. At the invitation of Diarmait Mac Murchada, a provincial king, and under the authority of Pope Adrian IV (the only Englishman to be elected pope), the Angevins invaded Ireland in 1169. Though initially intended to be kept as an independent kingdom, the failure of the Irish High King to ensure the terms of the Treaty of Windsor led Henry II, as King of England, to rule as effective monarch under the title of Lord of Ireland. This title was granted to his younger son, but when Henry's heir unexpectedly died, the title of King of England and Lord of Ireland became entwined in one person. + +By the Late Middle Ages, Great Britain was separated into the Kingdoms of England and Scotland. Power in Ireland fluxed between Gaelic kingdoms, Hiberno-Norman lords and the English-dominated Lordship of Ireland. A similar situation existed in the Principality of Wales, which was slowly being annexed into the Kingdom of England by a series of laws. During the course of the 15th century, the Crown of England would assert a claim to the Crown of France, thereby also releasing the King of England from being vassal of the King of France. In 1534, King Henry VIII, at first having been a strong defender of Roman Catholicism in the face of the Reformation, separated from the Roman Church after failing to secure a divorce from the Pope. His response was to place the King of England as "the only Supreme Head in Earth of the Church of England", thereby removing the authority of the Pope from the affairs of the English Church. Ireland, which had been held by the King of England as Lord of Ireland, but which strictly speaking had been a feudal possession of the Pope since the Norman invasion was declared a separate kingdom in personal union with England. + +Scotland meanwhile had remained an independent Kingdom. In 1603, that changed when the King of Scotland inherited the Crown of England, and consequently the Crown of Ireland also. The subsequent 17th century was one of political upheaval, religious division and war. English colonialism in Ireland of the 16th century was extended by large-scale Scottish and English colonies in Ulster. Religious division heightened, and the king of England came into conflict with parliament over his tolerance towards Catholicism. The resulting English Civil War or War of the Three Kingdoms led to a revolutionary republic in England. Ireland, largely Catholic, was mainly loyal to the king, but by military conquest was subsumed into the new republic. Following defeat to the parliament's army, large scale land distributions from loyalist Irish nobility to English commoners in the service of the parliamentary army created a new Ascendancy class which obliterated the remnants of Old English (Hiberno-Norman) and Gaelic Irish nobility in Ireland. The new ruling class was Protestant and English, whilst the populace was largely Catholic and Irish. This theme would influence Irish politics for centuries to come. When the monarchy was restored in England, the king found it politically impossible to restore the lands of former landowners in Ireland. The "Glorious Revolution" of 1688 repeated similar themes: a Catholic king pushing for religious tolerance in opposition to a Protestant parliament in England. The king's army was defeated at the Battle of the Boyne and at the militarily crucial Battle of Aughrim in Ireland. Resistance held out, eventually forcing the guarantee of religious tolerance in the Treaty of Limerick. However, the terms were never honoured and a new monarchy was installed. + +The Kingdoms of England and Scotland were unified in 1707 creating the Kingdom of Great Britain. Following an attempted republican revolution in Ireland in 1798, the Kingdoms of Ireland and Great Britain were unified in 1801, creating the United Kingdom. The Isle of Man and the Channel Islands remaining outside of the United Kingdom, but with their ultimate good governance being the responsibility of the British Crown (effectively the British government). Although the colonies of North America that would become the United States of America were lost by the start of the 19th century, the British Empire expanded rapidly elsewhere. A century later, it would cover one-third of the globe. Poverty in the United Kingdom remained desperate, however, and industrialisation in England led to terrible conditions for the working classes. Mass migrations following the Irish Famine and Highland Clearances resulted in the distribution of the islands' population and culture throughout the world and a rapid de-population of Ireland in the second half of the 19th century. Most of Ireland seceded from the United Kingdom after the Irish War of Independence and the subsequent Anglo-Irish Treaty (1919–1922), with the six counties that formed Northern Ireland remaining as an autonomous region of the UK. + +Politics + +There are two sovereign states in the British Isles: Ireland and the United Kingdom of Great Britain and Northern Ireland. Ireland, sometimes called the Republic of Ireland, governs five-sixths of the island of Ireland, with the remainder of the island forming Northern Ireland. Northern Ireland is a part of the United Kingdom of Great Britain and Northern Ireland, usually shortened to simply "the United Kingdom", which governs the remainder of the archipelago with the exception of the Isle of Man and the Channel Islands. The Isle of Man and the two Bailiwicks of the Channel Islands, Jersey and Guernsey, are known as the Crown Dependencies. They exercise constitutional rights of self-government and judicial independence; responsibility for international representation rests largely with the UK (in consultation with the respective governments); and responsibility for defence is reserved by the UK. The United Kingdom is made up of four constituent parts: England, Scotland and Wales, forming Great Britain, and Northern Ireland in the northeast of the island of Ireland. Of these, Scotland, Wales and Northern Ireland have devolved governments, meaning that each has its own parliament or assembly and is self-governing with respect to certain matters set down by law. For judicial purposes, Scotland, Northern Ireland and England and Wales (the latter being one entity) form separate legal jurisdictions, with there being no single law for the UK as a whole. + +Ireland, the United Kingdom and the three Crown dependencies are all parliamentary democracies, with their own separate parliaments. All parts of the United Kingdom return Members of Parliament (MPs) to parliament in London. In addition to this, voters in Scotland, Wales and Northern Ireland return members to a devolved parliament in Edinburgh and in Cardiff and an assembly in Belfast. Governance in the norm is by majority rule; however, Northern Ireland uses a system of power sharing whereby unionists and nationalists share executive posts proportionately and where the assent of both groups is required for the Northern Ireland Assembly to make certain decisions. (In the context of Northern Ireland, unionists are those who want Northern Ireland to remain a part of the United Kingdom and nationalists are those who want Northern Ireland to join with the rest of Ireland.) The British monarch is the head of state of the United Kingdom, while in the Republic of Ireland the head of state is the President of Ireland. + +Ireland is the only part of the isles that is a member state of the European Union (EU). The UK was a member between 1 January 1973 and 31 January 2020, but the Isle of Man and the Channel Islands were not. Since the partition of Ireland, an informal free-travel area has existed across the island of Ireland. This area required formal recognition in 1997 during the course of negotiations for the Amsterdam Treaty of the European Union, and (together with the Crown dependencies) is now known as the Common Travel Area. As such, Ireland is not part of the Schengen Area, which allows passport-free travel between most EU member states, and is the only member state with an opt-out from the obligation to join the Schengen Zone. + +Reciprocal arrangements allow British and Irish citizens specific voting rights in the two states. In Ireland, British citizens can vote in General and local elections, but not in European Parliament elections, constitutional referendums or presidential elections (for which there is no comparable franchise in the United Kingdom). In the United Kingdom, Irish and Commonwealth citizens can vote in every election for which British citizens are eligible. In the Crown dependencies, any resident can vote in general elections, but in Jersey and the Isle of Man only British citizens can run for office. These pre-date European Union law, and in both jurisdictions go further than what was required by European Union law (EU citizens may only vote in local elections in both states and European elections in Ireland). In 2008, a UK Ministry of Justice report investigating how to strengthen the British sense of citizenship proposed to end this arrangement, arguing that "the right to vote is one of the hallmarks of the political status of citizens; it is not a means of expressing closeness between countries". + +In addition, some civil bodies are organised throughout the islands as a whole—for example, the Samaritans, which is deliberately organised without regard to national boundaries on the basis that a service which is not political or religious should not recognise sectarian or political divisions. The Royal National Lifeboat Institution (RNLI), a charity that operates a lifeboat service, is also organised throughout the islands as a whole, covering the waters of the United Kingdom, Ireland, the Isle of Man, and the Channel Islands. + +The Northern Ireland peace process has led to a number of unusual arrangements between the Republic of Ireland, Northern Ireland and the United Kingdom. For example, citizens of Northern Ireland are entitled to the choice of Irish or British citizenship or both, and the Governments of Ireland and the United Kingdom consult on matters not devolved to the Northern Ireland Executive. The Northern Ireland Executive and the Government of Ireland also meet as the North/South Ministerial Council to develop policies common across the island of Ireland. These arrangements were made following the 1998 Good Friday Agreement. + +British–Irish Council + +Another body established under the Good Friday Agreement, the British–Irish Council, is made up of all of the states and territories of the British Isles. The British–Irish Parliamentary Assembly () predates the British–Irish Council and was established in 1990. Originally it comprised 25 members of the Oireachtas, the Irish parliament, and 25 members of the parliament of the United Kingdom, with the purpose of building mutual understanding between members of both legislatures. Since then the role and scope of the body has been expanded to include representatives from the Scottish Parliament, the Senedd (Welsh Parliament), the Northern Ireland Assembly, the States of Jersey, the States of Guernsey and the High Court of Tynwald (Isle of Man). + +The Council does not have executive powers but meets biannually to discuss issues of mutual importance. Similarly, the Parliamentary Assembly has no legislative powers but investigates and collects witness evidence from the public on matters of mutual concern to its members. Reports on its findings are presented to the Governments of Ireland and the United Kingdom. During the February 2008 meeting of the British–Irish Council, it was agreed to set up a standing secretariat that would serve as a permanent 'civil service' for the Council. Leading on from developments in the British–Irish Council, the chair of the British–Irish Inter-Parliamentary Assembly, Niall Blaney, has suggested that the body should shadow the British–Irish Council's work. + +Culture + +The United Kingdom and Ireland have separate media, although British television, newspapers and magazines are widely available in Ireland, giving people in Ireland a high level of familiarity with the culture of the United Kingdom. Irish newspapers are also available in the UK, and Irish state and private television are widely available in Northern Ireland. Certain reality TV shows have embraced the whole of the islands, for example The X Factor, seasons 3, 4 and 7 of which featured auditions in Dublin and were open to Irish voters, whilst the show previously known as Britain's Next Top Model became Britain and Ireland's Next Top Model in 2011. A few cultural events are organised for the island group as a whole. For example, the Costa Book Awards are awarded to authors resident in the UK or Ireland. The Mercury Music Prize is handed out every year to the best album from a British or Irish musician or group. + +Many globally popular sports had their modern rules codified in the British Isles, including golf, association football, cricket, rugby, snooker and darts, as well as many minor sports such as croquet, bowls, pitch and putt, water polo and handball. A number of sports are popular throughout the British Isles, the most prominent of which is association football. While this is organised separately in different national associations, leagues and national teams, even within the UK, it is a common passion in all parts of the islands. Rugby union is also widely enjoyed across the islands with four national teams from England, Ireland, Scotland and Wales. The British and Irish Lions is a team chosen from each national team and undertakes tours of the Southern Hemisphere rugby-playing nations every four years. Ireland plays as a united team, represented by players from both Northern Ireland and the Republic. These national rugby teams play each other each year for the Triple Crown as part of the Six Nations Championship. Also, since 2001, the professional club teams of Ireland, Scotland, Wales, Italy and South Africa compete against each other in the United Rugby Championship. + +The Ryder Cup in golf was originally played between a United States team and a team representing Great Britain and Ireland. From 1979 onwards, this was expanded to include the whole of Europe. + +Transport + +London Heathrow Airport is Europe's busiest airport in terms of passenger traffic, and the Dublin-London route is the busiest air route in Europe collectively, the busiest route out of Heathrow and the second-busiest international air route in the world. The English Channel and the southern North Sea are the busiest seaways in the world. The Channel Tunnel, opened in 1994, links Great Britain to France and is the second-longest rail tunnel in the world. + +The idea of building a tunnel under the Irish Sea has been raised since 1895, when it was first investigated. Several potential Irish Sea tunnel projects have been proposed, most recently the Tusker Tunnel between the ports of Rosslare and Fishguard proposed by The Institute of Engineers of Ireland in 2004. A rail tunnel was proposed in 1997 on a different route, between Dublin and Holyhead, by British engineering firm Symonds. Either tunnel, at , would be by far the longest in the world, and would cost an estimated £15 billion or €20 billion. A proposal in 2007, estimated the cost of building a bridge from County Antrim in Northern Ireland to Galloway in Scotland at £3.5bn (€5bn). + +See also + British Islands + Proposed British Isles fixed sea link connections + Extreme points of the British Isles + List of islands of the British Isles + +Notes + +References + +Further reading + + + + + + + + + + + A History of Britain: At the Edge of the World, 3500 B.C. – 1603 A.D. by Simon Schama, BBC/Miramax, 2000 + A History of Britain—The Complete Collection on DVD by Simon Schama, BBC 2002 + Shortened History of England by G.

Trevelyan Penguin Books + +External links + + An interactive geological map of the British Isles + + +Geography of Europe +Northwestern Europe +Regions of Europe +Archipelagoes of Europe +Basque (; ) is a language spoken by Basques and others of the Basque Country, a region that straddles the westernmost Pyrenees in adjacent parts of northern Spain and southwestern France. Linguistically, Basque is a language isolate (unrelated to any other existing languages). The Basques are indigenous to, and primarily inhabit, the Basque Country. The Basque language is spoken by 28.4% (751,500) of Basques in all territories. Of these, 93.2% (700,300) are in the Spanish area of the Basque Country and the remaining 6.8% (51,200) are in the French portion. + +Native speakers live in a contiguous area that includes parts of four Spanish provinces and the three "ancient provinces" in France. Gipuzkoa, most of Biscay, a few municipalities on the northern border of Álava and the northern area of Navarre formed the core of the remaining Basque-speaking area before measures were introduced in the 1980s to strengthen Basque fluency. By contrast, most of Álava, the westernmost part of Biscay, and central and southern Navarre are predominantly populated by native speakers of Spanish, either because Basque was replaced by Spanish over the centuries (as in most of Álava and central Navarre), or because it may never have been spoken there (as in parts of Enkarterri and south-eastern Navarre). + +In Francoist Spain, Basque language use was discouraged by the government's repressive policies. In the Basque Country, "Francoist repression was not only political, but also linguistic and cultural." Franco's regime suppressed Basque from official discourse, education, and publishing, making it illegal to register newborn babies under Basque names, and even requiring tombstone engravings in Basque to be removed. In some provinces the public use of Basque was suppressed, with people fined for speaking it. Public use of Basque was frowned upon by supporters of the regime, often regarded as a sign of anti-Francoism or separatism. Overall, in the 1960s and later, the trend reversed and education and publishing in Basque began to flourish. As a part of this process, a standardised form of the Basque language, called Euskara Batua, was developed by the Euskaltzaindia in the late 1960s. + +Besides its standardised version, the five historic Basque dialects are Biscayan, Gipuzkoan, and Upper Navarrese in Spain and Navarrese–Lapurdian and Souletin in France. They take their names from the historic Basque provinces, but the dialect boundaries are not congruent with province boundaries. Euskara Batua was created so that the Basque language could be used—and easily understood by all Basque speakers—in formal situations (education, mass media, literature), and this is its main use today. In both Spain and France, the use of Basque for education varies from region to region and from school to school. + +Basque is the only surviving language isolate in Europe. The current mainstream scientific view on the origin of the Basques and of their language is that early forms of Basque developed before the arrival of Indo-European languages in the area, i.e. before the arrival of Celtic and Romance languages in particular, as the latter today geographically surround the Basque-speaking region. Typologically, with its agglutinative morphology and ergative–absolutive alignment, Basque grammar remains markedly different from that of Standard Average European languages. Nevertheless, Basque has borrowed up to 40 percent of its vocabulary from Romance languages, and the Latin script is used for the Basque alphabet. + +Names of the language + +In Basque, the name of the language is officially (alongside various dialect forms). + +In French, the language is normally called , though has become common in recent times. Spanish has a greater variety of names for the language. Today, it is most commonly referred to as , , or . Both terms, and , are inherited from the Latin ethnonym , which in turn goes back to the Greek term (), an ethnonym used by Strabo in his (23 CE, Book III). + +The Spanish term , derived from Latin , has acquired negative connotations over the centuries and is not well-liked amongst Basque speakers generally. Its use is documented at least as far back as the 14th century when a law passed in Huesca in 1349 stated that —essentially penalising the use of Arabic, Hebrew, or Basque in marketplaces with a fine of 30 sols (the equivalent of 30 sheep). + +History and classification + +Basque is geographically surrounded by Romance languages but is a language isolate unrelated to them, and indeed, to any other language in the world. It is the last remaining descendant of one of the pre-Indo-European languages of Prehistoric Europe. Consequently, the prehistory of the Basque language may not be reconstructible by means of the traditional comparative method except by applying it to differences between dialects within the language. Little is known of its origins, but it is likely that an early form of the Basque language was present in and around the area of modern Basque Country before the arrival of the Indo-European languages in western Europe. + +Authors such as Miguel de Unamuno and Louis Lucien Bonaparte have noted that the words for "knife" (), "axe" (), and "hoe" () appear to derive from the word for "stone" (), and have therefore concluded that the language dates to prehistoric Europe when those tools were made of stone. Others find this unlikely: see the controversy. + +Latin inscriptions in preserve a number of words with cognates in the reconstructed proto-Basque language, for instance, the personal names and ( and mean 'young girl' and 'man', respectively in modern Basque). This language is generally referred to as Aquitanian and is assumed to have been spoken in the area before the Roman Republic's conquests in the western Pyrenees. Some authors even argue for late Basquisation, that the language moved westward during Late Antiquity after the fall of the Western Roman Empire into the northern part of Hispania into what is now Basque Country. + +Roman neglect of this area allowed Aquitanian to survive while the Iberian and Tartessian languages became extinct. Through the long contact with Romance languages, Basque adopted a sizeable number of Romance words. Initially the source was Latin, later Gascon (a branch of Occitan) in the north-east, Navarro-Aragonese in the south-east and Spanish in the south-west. + +Since 1968, Basque has been immersed in a revitalisation process, facing formidable obstacles. However, significant progress has been made in numerous areas. Six main factors have been identified to explain its relative success: + implementation and acceptance of Unified Basque (Batua), + integration of Basque in the education system + creation of media in Basque (radio, newspapers, and television) + the established new legal framework + collaboration between public institutions and people's organisations, and + campaigns for Basque language literacy. + +While those six factors influenced the revitalisation process, the extensive development and use of language technologies is also considered a significant additional factor. + +Hypotheses concerning Basque's connections to other languages +While accepted by a majority of linguists as a non-Indo-European language, many attempts have been made to link the Basque language with more geographically distant languages. Apart from pseudoscientific comparisons, the appearance of long-range linguistics gave rise to several attempts to connect Basque with geographically very distant language families. Historical work on Basque is challenging since written material and documentation only is available for some few hundred years. Almost all hypotheses concerning the origin of Basque are controversial, and the suggested evidence is not generally accepted by mainstream linguists. Some of these hypothetical connections are: + + Ligurian substrate: this hypothesis, proposed in the 19th century by d'Arbois de Jubainville, J. Pokorny, P. Kretschmer and several other linguists, encompasses the Basco-Iberian hypothesis. + Iberian: another ancient language once spoken in the Iberian Peninsula, shows several similarities with Aquitanian and Basque. However, not enough evidence exists to distinguish geographical connections from linguistic ones. Iberian itself remains unclassified. Eduardo Orduña Aznar claims to have established correspondences between Basque and Iberian numerals and noun case markers. + Vasconic substratum theory: this proposal, made by the German linguist Theo Vennemann, claims that enough toponymical evidence exists to conclude that Basque is the only survivor of a larger family that once extended throughout most of western Europe, and has also left its mark in modern Indo-European languages spoken in Europe. + Georgian: linking Basque to the Kartvelian languages is now widely discredited. The hypothesis was inspired by the existence of the ancient Kingdom of Iberia in the Caucasus and some similarities in societal practices and agriculture between the two populations. Historical comparisons are difficult due to the dearth of historical material for Basque and several of the Kartvelian languages. Typological similarities have been proposed for some of the phonological characteristics and most importantly for some of the details of the ergative constructions, but these alone cannot prove historical relatedness between languages since such characteristics are found in other languages across the world, even if not in Indo-European. According to J. P. Mallory, the hypothesis was also inspired by a Basque place-name ending in -dze which is common in Kartvelian. The theory suggested that Basque and Georgian were remnants of a pre-Indo-European group. + Northeast Caucasian languages, such as Chechen, are seen by some linguists as more likely candidates for a very distant connection. + Dené–Caucasian: based on the possible Caucasian link, some linguists, for example John Bengtson and Merritt Ruhlen, have proposed including Basque in the Dené–Caucasian superfamily of languages, but this proposed superfamily includes languages from North America and Eurasia, and its existence is highly controversial. + Indo-European: a genetic link between Basque and the Indo-European languages has been proposed by Forni (2013). This proposal is rejected by most reviewers, both including scholars adhering to the mainstream view of Basque as a language isolate (Gorrochategui, Lakarra), as well as proponents of wide-range genetic relations (Bengtson). + +Geographic distribution + +The region where Basque is spoken has become smaller over centuries, especially at the northern, southern, and eastern borders. Nothing is known about the limits of this region in ancient times, but on the basis of toponyms and epigraphs, it seems that in the beginning of the Common Era it stretched to the river Garonne in the north (including the south-western part of present-day France); at least to the Val d'Aran in the east (now a Gascon-speaking part of Catalonia), including lands on both sides of the Pyrenees; the southern and western boundaries are not clear at all. + +The Reconquista temporarily counteracted this contracting tendency when the Christian lords called on northern Iberian peoples — Basques, Asturians, and "Franks" — to colonise the new conquests. The Basque language became the main everyday language, while other languages like Spanish, Gascon, French, or Latin were preferred for the administration and high education. + +By the 16th century, the Basque-speaking area was reduced basically to the present-day seven provinces of the Basque Country, excluding the southern part of Navarre, the south-western part of Álava, and the western part of Biscay, and including some parts of Béarn. + +In 1807, Basque was still spoken in the northern half of Álava—including its capital city Vitoria-Gasteiz—and a vast area in central Navarre, but in these two provinces, Basque experienced a rapid decline that pushed its border northwards. In the French Basque Country, Basque was still spoken in all the territory except in Bayonne and some villages around, and including some bordering towns in Béarn. + +In the 20th century, however, the rise of Basque nationalism spurred increased interest in the language as a sign of ethnic identity, and with the establishment of autonomous governments in the Southern Basque Country, it has recently made a modest comeback. In the Spanish part, Basque-language schools for children and Basque-teaching centres for adults have brought the language to areas such as western Enkarterri and the Ribera del Ebro in southern Navarre, where it is not known to ever have been widely spoken; and in the French Basque Country, these schools and centres have almost stopped the decline of the language. + +Official status + +Historically, Latin or Romance languages have been the official languages in this region. However, Basque was explicitly recognised in some areas. For instance, the fuero or charter of the Basque-colonised Ojacastro (now in La Rioja) allowed the inhabitants to use Basque in legal processes in the 13th and 14th centuries. + +The Spanish Constitution of 1978 states in Article 3 that the Spanish language is the official language of the nation, but allows autonomous communities to provide a co-official language status for the other languages of Spain. Consequently, the Statute of Autonomy of the Basque Autonomous Community establishes Basque as the co-official language of the autonomous community. The Statute of Navarre establishes Spanish as the official language of Navarre, but grants co-official status to the Basque language in the Basque-speaking areas of northern Navarre. Basque has no official status in the French Basque Country and French citizens are barred from officially using Basque in a French court of law. However, the use of Basque by Spanish nationals in French courts is permitted (with translation), as Basque is officially recognised on the other side of the border. + +The positions of the various existing governments differ with regard to the promotion of Basque in areas where Basque is commonly spoken. The language has official status in those territories that are within the Basque Autonomous Community, where it is spoken and promoted heavily, but only partially in Navarre. The Ley del Vascuence ("Law of Basque"), seen as contentious by many Basques, but considered fitting Navarra's linguistic and cultural diversity by some of the main political parties of Navarre, divides Navarre into three language areas: Basque-speaking, non-Basque-speaking, and mixed. Support for the language and the linguistic rights of citizens vary, depending on the area. Others consider it unfair, since the rights of Basque speakers differ greatly depending on the place they live. + +Demographics + +The 2016 sociolinguistic survey of all Basque-speaking territories showed that in 2016, of all people aged 16 and above: + In the Basque Autonomous Community, 33.9% were fluent Basque speakers, 19.1% passive speakers and 47% did not speak Basque. The percentage was highest in Gipuzkoa (50.6% speakers) and Bizkaia (27.6%) and lowest in Álava (19.2%). These results represent an increase from previous years (30.1% in 2006, 29.5% in 2001, 27.7% in 1996 and 24.1% in 1991). The highest percentage of speakers can now be found in the 16–24 age range (57.5%) vs. 25.0% in the 65+ age range. + In French Basque Country, in 2006, 20.5% were fluent Basque speakers, 9.3% passive speakers, and 70.1% did not speak Basque. The percentage was highest in Labourd and Soule (49.5% speakers) and lowest in the Bayonne-Anglet-Biarritz conurbation (8.4%). Because the French Basque Country is not under the influence of the Basque Autonomous Country government, the region has fewer incentives to learn the language by government authorities. As such, these results represent another decrease from previous years (22.5% in 2006, 24.8% in 2001 and 26.4 in 1996 or 56,146 in 1996 to 51,197 in 2016). The highest percentage of speakers is in the 65+ age range (28.1%). The lowest percentage is found in the 35-49 age range (14.6%), but there is a slight increase in the 16–24 age range (18.9%) + In Navarre, 12.9% were fluent Basque speakers, 10.3% passive speakers, and 76.7% did not speak Basque. The percentage was highest in the Basque-speaking zone in the north (61.1% speakers) and lowest in the non-Basque-speaking zone in the south (2.7%). These results represent a slight increase from previous years (11.1% in 2006,10.3% in 2001, 9.6% in 1996 and 9.5% in 1991). The highest percentage of speakers can now be found in the 16–24 age range (25.8%) vs. 8.3% in the 65+ age range. + +Taken together, in 2016, of a total population of 3,131,464 (2,191,688 in the Autonomous Community; 297,847 in the Northern provinces; and 640,647 in Navarre), 751,527 spoke Basque (aged 16 and above). This amounts to 28.4% Basque bilinguals overall, 16.4% passive speakers, and 55.2% non-speakers. Compared to the 1991 figures, this represents an overall increase of 223,000, from 528,500 (from a population of 2,371,100) 25 years previously. This number tends to increase, since 55.4% of the population between 16 and 24 years old spoke Basque in 2016, compared to only 22.5% in 1991. + +While there is a general increase in the number of Basque-speaking during this period, this is mainly because of bilingualism. Basque transmission as a sole mother tongue has decreased from 19% in 1991 to 15.1% in 2016, while Basque and another language being used as mother language increased from 3% to 5.4% in the same time period. General public attitude towards efforts to promote the Basque language have also been more positive, with the share of people against these efforts falling from 20.9% in 1991 to 16% in 2016. + +Basque is used as a language of commerce both in the Basque Country and in locations around the world where Basques immigrated throughout history. + +Dialects + +The modern Basque dialects show a high degree of dialectal divergence, sometimes making cross-dialect communication difficult. This is especially true in the case of Biscayan and Souletin, which are regarded as the most divergent Basque dialects. + +Modern Basque dialectology distinguishes five dialects: + Biscayan or "Western" + Gipuzkoan or "Central" + Upper Navarrese + Navarro-Lapurdian + Souletin (Zuberoan) + +These dialects are divided in 11 subdialects, and 24 minor varieties among them. +According to Koldo Zuazo, the Biscayan dialect or "Western" is the most widespread dialect, with around 300,000 speakers out of a total of around 660,000 speakers. This dialect is divided in two minor subdialects: the Western Biscayan and Eastern Biscayan, plus transitional dialects. + +Influence on other languages + +Although the influence of the neighbouring Romance languages on the Basque language (especially the lexicon, but also to some degree Basque phonology and grammar) has been much more extensive, it is usually assumed that there has been some feedback from Basque into these languages as well. In particular Gascon and Aragonese, and to a lesser degree Spanish are thought to have received this influence in the past. In the case of Aragonese and Gascon, this would have been through substrate interference following language shift from Aquitanian or Basque to a Romance language, affecting all levels of the language, including place names around the Pyrenees. + +Although a number of words of alleged Basque origin in the Spanish language are circulated (e.g. 'anchovies', 'dashing, gallant, spirited', 'puppy', etc.), most of these have more easily explicable Romance etymologies or not particularly convincing derivations from Basque. Ignoring cultural terms, there is one strong loanword candidate, , long considered the source of the Pyrenean and Iberian Romance words for "left (side)" (, , ). The lack of initial in Gascon could arguably be due to a Basque influence but this issue is under-researched. + +The other most commonly claimed substrate influences: + the Old Spanish merger of and . + the simple five vowel system. + change of initial into (e.g. fablar → hablar, with Old Basque lacking but having ). + voiceless alveolar retracted sibilant , a sound transitional between laminodental and palatal ; this sound also influenced other Ibero-Romance languages and Catalan. + +The first two features are common, widespread developments in many Romance (and non-Romance) languages. The change of to occurred historically only in a limited area (Gascony and Old Castile) that corresponds almost exactly to areas where heavy Basque bilingualism is assumed, and as a result has been widely postulated (and equally strongly disputed). Substrate theories are often difficult to prove (especially in the case of phonetically plausible changes like to ). As a result, although many arguments have been made on both sides, the debate largely comes down to the a priori tendency on the part of particular linguists to accept or reject substrate arguments. + +Examples of arguments against the substrate theory, and possible responses: + Spanish did not fully shift to , instead, it has preserved before consonants such as and (cf fuerte, frente). (On the other hand, the occurrence of in these words might be a secondary development from an earlier sound such as or and learned words (or words influenced by written Latin form). Gascon does have in these words, which might reflect the original situation.) + Evidence of Arabic loanwords in Spanish points to continuing to exist long after a Basque substrate might have had any effect on Spanish. (On the other hand, the occurrence of in these words might be a late development. Many languages have come to accept new phonemes from other languages after a period of significant influence. For example, French lost /h/ but later regained it as a result of Germanic influence, and has recently gained as a result of English influence.) + Basque regularly developed Latin into or . + The same change also occurs in parts of Sardinia, Italy and the Romance languages of the Balkans where no Basque substrate can be reasonably argued for. (On the other hand, the fact that the same change might have occurred elsewhere independently does not disprove substrate influence. Furthermore, parts of Sardinia also have prothetic or before initial , just as in Basque and Gascon, which may actually argue for some type of influence between both areas.) + +Beyond these arguments, a number of nomadic groups of Castile are also said to use or have used Basque words in their jargon, such as the gacería in Segovia, the mingaña, the Galician fala dos arxinas and the Asturian Xíriga. + +Part of the Romani community in the Basque Country speaks Erromintxela, which is a rare mixed language, with a Kalderash Romani vocabulary and Basque grammar. + +Basque pidgins +A number of Basque-based or Basque-influenced pidgins have existed. In the 16th century, Basque sailors used a Basque–Icelandic pidgin in their contacts with Iceland. The Algonquian–Basque pidgin arose from contact between Basque whalers and the Algonquian peoples in the Gulf of Saint Lawrence and Strait of Belle Isle. + +Phonology + +Vowels + +The Basque language features five vowels: , , , and (the same that are found in Spanish, Asturian and Aragonese). In the Zuberoan dialect, extra phonemes are featured: + the close front rounded vowel , graphically represented as ; + a set of contrasting nasal vowels. + +There is no distinctive vowel length in Basque, although vowels can be lengthened for emphasis. The mid vowels and are raised before nasal consonants. + +Basque has an a-Elision Rule, according to which the vowel is elided before any following vowel. This does not prevent the existence of diphthongs with present. + +There are six diphthongs in Basque, all falling and with or as the second element. + +Consonants + +In syllable-final position, all plosives are devoiced and are spelled accordingly in Standard Basque. When between vowels, and often when after or , the voiced plosives , , and , are pronounced as the corresponding fricatives , , and . + +Basque has a distinction between laminal and apical articulation for the alveolar fricatives and affricates. With the laminal alveolar fricative , the friction occurs across the blade of the tongue, the tongue tip pointing toward the lower teeth. This is the usual in most European languages. It is written with an orthographic . By contrast, the voiceless apicoalveolar fricative is written ; the tip of the tongue points toward the upper teeth and friction occurs at the tip (apex). For example, zu "you" (singular, respectful) is distinguished from su "fire". The affricate counterparts are written and . So, etzi "the day after tomorrow" is distinguished from etsi "to give up"; atzo "yesterday" is distinguished from atso "old woman". + +In the westernmost parts of the Basque country, only the apical and the alveolar affricate are used. + +Basque also features postalveolar sibilants (, written , and , written ), sounding like English sh and ch. + +The letter has a variety of realisations according to the regional dialect: , as pronounced from west to east in south Bizkaia and coastal Lapurdi, central Bizkaia, east Bizkaia and Gipuzkoa, south Navarre, inland Lapurdi and Low Navarre, and Zuberoa, respectively. + +The letter is pronounced in the northern dialects, but not pronounced in the southern ones. Unified Basque spells it except when it is predictable, in a position following a consonant. + +Unless they are recent loanwords (e.g. Ruanda "Rwanda", radar, robot ... ), words may not have initial . In older loans, initial r- took a prosthetic vowel, resulting in err- (Erroma "Rome", Errusia "Russia"), more rarely irr- (for example irratia "radio", irrisa "rice") and arr- (for example arrazional "rational"). + +Basque does not have in syllable final position, and syllable-final assimilates to the place of articulation of following plosives. As a result, is pronounced like , and is realized as . + +Palatalization +Basque has two types of palatalization, automatic palatalization and expressive palatalization. Automatic palatalization occurs in western Labourd, much of Navarre, all of Gipuzkoa, and nearly all of Biscay. As a result of automatic palatalization, and become the palatal nasal and the palatal lateral respectively after the vowel and before another vowel. An exception is the loanword 'lily'. The same palatalization occurs after the semivowel of the diphthongs ai, ei, oi, ui. This palatalization occurs in a wider area, including Soule, all of Gipuzkoa and Biscay, and almost all of Navarre. In a few regions, and can be palatalized even in the absence of a following vowel. After palatalization, the semivowel is usually absorbed by the palatal consonant. This can be seen in older spellings, such as instead of modern 'degree'. That said, the modern orthography for Standard Basque ignores automatic palatalization. + +In certain regions of Gipuzkoa and Biscay, intervocalic is often palatalized after and especially . It may become indistinguishable from the affricate , spelled , so 'father' may sound like it were spelled or . This type of palatalization is far from general, and is often viewed as substandard. + +In Goizueta Basque, there are a few examples of being palatalized after , and optional palatalization of . For example, 'seedbed' becomes , and 'lamb' can be . + +Basque nouns, adjectives, and adverbs can be expressively palatalized. These express 'smallness', rarely literal and often showing affection, in nouns, and mitigation in adjectives and adverbs. This is often used in the formation of pet names and nicknames. In words containing one or more sibilant, these sibilants are palatalized in order to form the palatalized form. That is, s and z become x, and ts and tz become tx. As a result, 'man' becomes 'little fellow', 'crazy, insane' becomes 'silly, foolish', and 'lamb' becomes 'lambkin, young lamb'. +In words without sibilants, , , , and can become palatalized. This palatalization is indicated in writing with a double consonant, except in the case of palatalized which is written . Thus, 'drop' becomes 'droplet', and 'grey' becomes 'grey and pretty, greyish'. + +The pronunciation of tt and dd, and the existence of dd, differ by dialect. In the Gipuzkoan and Biscayan dialects tt is often pronounced the same as tx, that is, as , and dd does not exist. Likewise, in Goizueta Basque, tt is a voiceless palatal stop and the corresponding voiced palatal stop, , is absent except as an allophone of . In Goizueta Basque, is sometimes the result of an affectionate palatalization of . + +Palatalization of the rhotics is rare and only occurs in the eastern dialects. When palatalized, the rhotics become the palatal lateral . Likewise, palatalization of velars, resulting in tt or tx, is quite rare. + +A few common words, such as 'dog', pronounced , use palatal sounds even though in current usage they have lost the diminutive sense, the corresponding non-palatal forms now acquiring an augmentative or pejorative sense: 'big dog'. + +Sandhi +There are some rules which govern the behavior of consonants in contact with each other. These apply both within and between words. When two plosives meet, the first one is dropped, and the second must become voiceless. If a sibilant follows a plosive, the plosive is dropped, and the sibilant becomes the corresponding affricate. When a plosive follows an affricate, the affricate becomes a sibilant, and a voiced plosive is devoiced. When a voiced plosive follows a sibilant, it is devoiced except in very slow and careful speech. In the central dialects of Basque, a sibilant turns into an affricate when it follows a liquid or a nasal. When a plosive follows a nasal, there's a strong tendency for it to become voiced. + +Stress and pitch + +Basque features great dialectal variation in accentuation, from a weak pitch accent in the western dialects to a marked stress in central and eastern dialects, with varying patterns of stress placement. Stress is in general not distinctive (and for historical comparisons not very useful); there are, however, a few instances where stress is phonemic, serving to distinguish between a few pairs of stress-marked words and between some grammatical forms (mainly plurals from other forms), e.g. basóà ("the forest", absolutive case) vs. básoà ("the glass", absolutive case; an adoption from Spanish ); basóàk ("the forest", ergative case) vs. básoàk ("the glass", ergative case) vs. básoak ("the forests" or "the glasses", absolutive case). + +Given its great deal of variation among dialects, stress is not marked in the standard orthography and Euskaltzaindia (the Academy of the Basque Language) provides only general recommendations for a standard placement of stress, basically to place a high-pitched weak stress (weaker than that of Spanish, let alone that of English) on the second syllable of a syntagma, and a low-pitched even-weaker stress on its last syllable, except in plural forms where stress is moved to the first syllable. + +This scheme provides Basque with a distinct musicality that differentiates its sound from the prosodical patterns of Spanish (which tends to stress the second-to-last syllable). Some Euskaldun berriak ("new Basque-speakers", i.e. second-language Basque-speakers) with Spanish as their first language tend to carry the prosodical patterns of Spanish into their pronunciation of Basque, e.g. pronouncing nire ama ("my mum") as nire áma (– – ´ –), instead of as niré amà (– ´ – `). + +Morphophonology + +The combining forms of nominals in final vary across the regions of the Basque Country. The can stay unchanged, be lowered to an , or it can be lost. Loss is most common in the east, while lowering is most common in the west. For instance, buru, "head", has the combining forms buru- and bur-, as in buruko, "cap", and burko, "pillow", whereas katu, "cat", has the combining form kata-, as in katakume, "kitten". Michelena suggests that the lowering to is generalised from cases of Romance borrowings in Basque that retained Romance stem alternations, such as kantu, "song" with combining form kanta-, borrowed from Romance canto, canta-. + +Grammar + +Basque is an ergative–absolutive language. The subject of an intransitive verb is in the absolutive case (which is unmarked), and the same case is used for the direct object of a transitive verb. The subject of the transitive verb is marked differently, with the ergative case (shown by the suffix -k). This also triggers main and auxiliary verbal agreement. + +The auxiliary verb, which accompanies most main verbs, agrees not only with the subject, but with any direct object and the indirect object present. Among European languages, this polypersonal agreement is found only in Basque, some languages of the Caucasus (especially the Kartvelian languages), Mordvinic languages, Hungarian, and Maltese (all non-Indo-European). The ergative–absolutive alignment is also rare among European languages—occurring only in some languages of the Caucasus—but not infrequent worldwide. + +Consider the phrase: + +Martin-ek is the agent (transitive subject), so it is marked with the ergative case ending -k (with an epenthetic -e-). Egunkariak has an -ak ending, which marks plural object (plural absolutive, direct object case). The verb is , in which is a kind of gerund ("buying") and the auxiliary means "he/she (does) them for me". This can be split like this: + di- is used in the present tense when the verb has a subject (ergative), a direct object (absolutive), and an indirect object, and the object is him/her/it/them. + -zki- means the absolutive (in this case the newspapers) is plural; if it were singular there would be no infix; and + -t or -da- means "to me/for me" (indirect object). + in this instance there is no suffix after -t. A zero suffix in this position indicates that the ergative (the subject) is third person singular (he/she/it). + +The auxiliary verb is composed as di-zki-da-zue and means 'you pl. (do) them for me' + di- indicates that the main verb is transitive and in the present tense + -zki- indicates that the direct object is plural + -da- indicates that the indirect object is me (to me/for me; -t becomes -da- when not final) + -zue indicates that the subject is you (plural) + +The pronoun zuek 'you (plural)' has the same form both in the nominative or absolutive case (the subject of an intransitive sentence or direct object of a transitive sentence) and in the ergative case (the subject of a transitive sentence). In spoken Basque, the auxiliary verb is never dropped even if it is redundant, e.g. in 'you (pl.) are buying the newspapers for me'. However, the pronouns are almost always dropped, e.g. zuek in 'you (pl.) are buying the newspapers for me'. The pronouns are used only to show emphasis: 'it is you (pl.) who buys the newspapers for me', or 'it is me for whom you buy the newspapers'. + +Modern Basque dialects allow for the conjugation of about fifteen verbs, called synthetic verbs, some only in literary contexts. These can be put in the present and past tenses in the indicative and subjunctive moods, in three tenses in the conditional and potential moods, and in one tense in the imperative. Each verb that can be taken intransitively has a nor (absolutive) paradigm and possibly a nor-nori (absolutive–dative) paradigm, as in the sentence Aititeri txapela erori zaio ("The hat fell from grandfather['s head]"). Each verb that can be taken transitively uses those two paradigms for antipassive-voice contexts in which no agent is mentioned (Basque lacks a passive voice, and displays instead an antipassive voice paradigm), and also has a nor-nork (absolutive–ergative) paradigm and possibly a nor-nori-nork (absolutive–dative–ergative) paradigm. This last is exemplified by dizkidazue above. In each paradigm, each constituent noun can take on any of eight persons, five singular and three plural, with the exception of nor-nori-nork in which the absolutive can only be third person singular or plural. The most ubiquitous auxiliary, izan, can be used in any of these paradigms, depending on the nature of the main verb. + +There are more persons in the singular (5) than in the plural (3) for synthetic (or filamentous) verbs because of the two familiar persons—informal masculine and feminine second person singular. The pronoun hi is used for both of them, but where the masculine form of the verb uses a -k, the feminine uses an -n. This is a property rarely found in Indo-European languages. The entire paradigm of the verb is further augmented by inflecting for "listener" (the allocutive) even if the verb contains no second person constituent. If the situation calls for the familiar masculine, the form is augmented and modified accordingly. Likewise for the familiar feminine. +(Gizon bat etorri da, "a man has come"; gizon bat etorri duk, "a man has come [you are a male close friend]", gizon bat etorri dun, "a man has come [you are a female close friend]", gizon bat etorri duzu, "a man has come [I talk to you (Sir / Madam)]") This multiplies the number of possible forms by nearly three. Still, the restriction on contexts in which these forms may be used is strong, since all participants in the conversation must be friends of the same sex, and not too far apart in age. Some dialects dispense with the familiar forms entirely. Note, however, that the formal second person singular conjugates in parallel to the other plural forms, perhaps indicating that it was originally the second person plural, later came to be used as a formal singular, and then later still the modern second person plural was formulated as an innovation. + +All the other verbs in Basque are called periphrastic, behaving much like a participle would in English. These have only three forms in total, called aspects: perfect (various suffixes), habitual (suffix -t[z]en), and future/potential (suffix. -ko/-go). Verbs of Latinate origin in Basque, as well as many other verbs, have a suffix -tu in the perfect, adapted from the Latin perfect passive -tus suffix. The synthetic verbs also have periphrastic forms, for use in perfects and in simple tenses in which they are deponent. + +Within a verb phrase, the periphrastic verb comes first, followed by the auxiliary. + +A Basque noun-phrase is inflected in 17 different ways for case, multiplied by four ways for its definiteness and number (indefinite, definite singular, definite plural, and definite close plural: euskaldun [Basque speaker], euskalduna [the Basque speaker, a Basque speaker], euskaldunak [Basque speakers, the Basque speakers], and euskaldunok [we Basque speakers, those Basque speakers]). These first 68 forms are further modified based on other parts of the sentence, which in turn are inflected for the noun again. It has been estimated that, with two levels of recursion, a Basque noun may have 458,683 inflected forms. + +The common noun "liburu" (book) is declined as follows: + +The proper name "Mikel" (Michael) is declined as follows: + +Within a noun phrase, modifying adjectives follow the noun. As an example of a Basque noun phrase, etxe zaharrean "in the old house" is morphologically analysed as follows by Agirre et al. + +Basic syntactic construction is subject–object–verb (unlike Spanish, French or English where a subject–verb–object construction is more common). The order of the phrases within a sentence can be changed for thematic purposes, whereas the order of the words within a phrase is usually rigid. As a matter of fact, Basque phrase order is topic–focus, meaning that in neutral sentences (such as sentences to inform someone of a fact or event) the topic is stated first, then the focus. In such sentences, the verb phrase comes at the end. In brief, the focus directly precedes the verb phrase. This rule is also applied in questions, for instance, What is this? can be translated as Zer da hau? or Hau zer da?, but in both cases the question tag zer immediately precedes the verb da. This rule is so important in Basque that, even in grammatical descriptions of Basque in other languages, the Basque word galdegai (focus) is used. + +In negative sentences, the order changes. Since the negative particle ez must always directly precede the auxiliary, the topic most often comes beforehand, and the rest of the sentence follows. This includes the periphrastic, if there is one: Aitak frantsesa irakasten du, "Father teaches French", in the negative becomes Aitak ez du frantsesa irakasten, in which irakasten ("teaching") is separated from its auxiliary and placed at the end. + +Vocabulary + +Through contact with neighbouring peoples, Basque has adopted many words from Latin, Spanish, French and Gascon, among other languages. There are a considerable number of Latin loans (sometimes obscured by being subject to Basque phonology and grammar for centuries), for example: lore ("flower", from florem), errota ("mill", from rotam, "[mill] wheel"), gela ("room", from cellam), gauza ("thing", from causa). + +Writing system + +Basque is written using the Latin script including and sometimes and . Basque does not use for native words, but the Basque alphabet (established by Euskaltzaindia) does include them for loanwords: +⟨Aa, Bb, Cc, (and, as a variant, Çç), Dd, Ee, Ff, Gg, Hh, Ii, Jj, Kk, Ll, Mm, Nn, Ññ, Oo, Pp, Qq, Rr, Ss, Tt, Uu, Vv, Ww, Xx, Yy, Zz⟩ + +The phonetically meaningful digraphs are treated as pairs of letters. + +All letters and digraphs represent unique phonemes. The main exception is when precedes and , which in most dialects palatalises their sounds into and , even if these are not written.

Units of ten are usually a horizontal line through the vertical. The twenties are based on a circle with intersecting lines. This system is no longer in general use but is occasionally employed for decorative purposes. + +Examples + +Article 1 of the Universal Declaration of Human Rights + + + +Language video gallery + +See also + Basque dialects + Vasconic languages + List of Basques + Basque Country + Late Basquisation + Languages of France + Languages of Spain + Aquitanian language + List of ideophones in Basque + Wiktionary: Swadesh list of Basque words + Basque literature + +References + +Further reading + +General and descriptive grammars + Allières, Jacques (1979): Manuel pratique de basque, "Connaissance des langues" v. 13, A. & J.

He is also the co-composer of the musicals Chess, Kristina från Duvemåla, and Mamma Mia! He co-produced the films Mamma Mia! and Mamma Mia! Here We Go Again with fellow ABBA member and close friend Benny Andersson. He is the oldest member of the group. + +Early life +Björn Kristian Ulvæus was born in Gothenburg on 25 April 1945. In 1951, he moved with his family to Västervik, Kalmar County. His parents were Aina Eliza Viktoria (née Bengtsson; 1909–2005) and Erik Gunnar Ulvaeus (1912–1999). Ulvaeus has one sister, Eva Margareta (born 1948). Ulvaeus studied business and law at Lund University after undertaking his military service, alongside comedian Magnus Holmström. + +Career + +Pre-ABBA +Before gaining international recognition with ABBA, Ulvaeus was a member of the Swedish folk-schlager band Hootenanny Singers, known earlier as the "West Bay Singers", who had an enormous following in Scandinavia. While on the road in southern Sweden in 1966, they encountered the Hep Stars, and Ulvaeus quickly became friends with the group's keyboard player, Benny Andersson. The two musicians shared a passion for songwriting, and each found a composing partner in the other. On meeting again that summer, they composed their first song together: "Isn't It Easy To Say", a song soon to be recorded by Andersson's group. The two continued teaming up for music, helping out each other's bands in the recording studio, and adding guitar or keyboards respectively to the recordings. In 1968, they composed two songs together: "A Flower in My Garden", recorded by Hep Stars, and their first real hit "Ljuva Sextiotal", for which Stig Anderson wrote lyrics. The latter, a cabarét-style ironic song about the 1960s, was submitted for the 1969 Swedish heats for the Eurovision Song Contest, but was rejected; it was later recorded by diva Brita Borg. Another hit came in 1969 with "Speleman", also recorded by Hep Stars. + +While filming a nostalgic schlager special for television in March 1969, Björn met eighteen-year-old future wife and singer-songwriter Agnetha Fältskog. + +Björn Ulvaeus continued recording and touring with Hootenanny Singers to great acclaim while working as in-house producer at Polar Record Company (headed by future manager Stig Anderson), with Benny as his new partner. The twosome produced records by other artists and continued writing songs together. Polar artist Arne Lamberts Swedish version of "A Flower in My Garden" ("Fröken Blåklint") was one of Björn & Benny's first in-house productions. In December 1969, they recorded the new song "She's My Kind of Girl", which became their first single as a duo. It was released in March 1970, giving them a minor hit in Sweden and a top-ten hit in Japan two years later. + +The Hootenanny Singers entered Svensktoppen, the Swedish radio charts, in 1970 with "Omkring Tiggarn Från Luossa", a cover of an old folk-schlager song. It remained on the charts for 52 consecutive weeks, a record which endured until 1990; the song was produced by Björn and Benny, and had Ulvaeus's solo vocal and Benny's piano. + +ABBA years + +Björn Ulvaeus's girlfriend Agnetha Fältskog eventually joined Björn&Benny becoming Björn, Benny & Agnetha, Frida eventually shortening it to ABBA. Björn was the guitar player in the band, but he also sang lead vocals in the following songs: People Need Love, Merry Go Round, Santa Rosa, Another Town Another Train, I Saw It in the Mirror, Love Isn't Easy (But It Sure Is Hard Enough), He Is Your Brother, Rock'n Roll Band, She's My Kind of Girl, Honey Honey, Sitting in the Palmtree, King King Song, Watch Out, Man in the Middle, Rock Me, Crazy World, Why Did It Have To Be Me?, Summer Night City, Does Your Mother Know, Two for the Price Of One. + +Björn got divorced with Agnetha Fältskog and the band broke up shortly after the divorce. + +Post-ABBA +After ABBA went on hiatus in 1982, Ulvaeus and Andersson created the musicals Chess, a collaboration with lyricist Tim Rice, Kristina från Duvemåla (based on The Emigrants novels by Swedish writer Vilhelm Moberg), and Mamma Mia! (based on ABBA songs). + +Together with Andersson, Ulvaeus was nominated for the Drama Desk Award in the category "Outstanding Music" (for the musical Chess), and for a Tony Award in a category "Best Orchestrations" (for the musical Mamma Mia!). The original cast recordings for both musicals were nominated for a Grammy Award. + +For the 2004 semi-final of the Eurovision Song Contest in Istanbul, thirty years after ABBA had won the 1974 contest in Brighton, UK, Ulvaeus appeared briefly in a special comedy video made for the interval act, entitled "Our Last Video". Each of the four members of the group appeared briefly in cameo roles, as did others such as Cher and Rik Mayall. The video was not included in the official DVD release of the Eurovision Contest, but was issued as a separate DVD release. It was billed as the first time the four had worked together since the group split. In fact, they each filmed their appearances separately. + +Ulvaeus also shared with Andersson "The Special International Ivor Novello Award" from the British Academy of Songwriters, Composers and Authors, "The Music Export Prize" from the Swedish Ministry of Industry and Trade (2008), and "Lifetime Achievement Award" from the Swedish Music Publishers Association (SMFF). + +On 15 April 2013, it was officially announced by the EBU and the SVT that Ulvaeus and Andersson, with the late Swedish DJ and record producer Avicii, had composed the anthem for the 2013 Eurovision Song Contest. The song was performed for the first time in the Final on 18 May. + +Ulvaeus reunited with ABBA in 2018. + +In 2019, Ulvaeus worked with Swedish songwriter Andreas Carlsson to arrange an English dub of Tomas Ledin's jukebox musical film En del av mitt hjärta (English: A Piece of My Heart) directed by Edward af Sillén. Ulvaeus was asked to write English lyrics for Ledin's songs as they are long-term friends. + +In 2020, Björn Ulvaeus has been appointed President of CISAC, the International Confederation of Societies of Authors and Composers. + +On 2 September 2021, via YouTube livestream, ABBA announced their virtual concert residency "ABBA Voyage", as well as the release of a studio album, recorded between 2017 and 2021. The new record, their first in 40 years, features ten tracks, including "I Still Have Faith In You" and "Don't Shut Me Down", which were first shown in the aforementioned livestream event and released as a double A-side single. On 5 November 2021, the Voyage album was released worldwide, and on 27 May 2022, ABBA Voyage opened in a purpose-built venue named the ABBA Arena at the Queen Elizabeth Olympic Park in London. + +In October 2023, it was confirmed that Ulvaeus would be the keynote speaker for The Business Day at Bridlington Spa in the United Kingdom on Friday 7 June 2024. Ulvaeus is expected to discuss the creation of ABBA Voyage, leadership, entrepreneurship, Artificial Intelligence (AI), Technology, Innovation, Meta Data and the complexity of business in the music industry. + +Personal life +On 6 July 1971, Ulvaeus married Agnetha Fältskog. They had two children: Linda Elin Ulvaeus (born 23 February 1973), and Peter Christian Ulvaeus (born 4 December 1977). The couple separated in early 1979, and their divorce was finalised in July 1980. + +Ulvaeus married music journalist Lena Källersjö on 6 January 1981. They have two daughters: Emma Eleonora (born 3 January 1982) and Anna Linnea (born 29 April 1986). Ulvaeus and Källersjö lived on a private island in Djursholm, an upscale area in Danderyd Municipality north of Stockholm. From 1984 to 1990 they lived in the United Kingdom, where Ulvaeus founded an IT business with his brother. In February 2022, Ulvaeus and Källersjö announced their separation. + +Ulvaeus is one of the four owners (along with Per Gessle) of NoteHeads, a Swedish company which publishes the music notation program Igor Engraver. + +Ulvaeus is a member of the International Humanist and Ethical Union's Swedish member organisation Humanisterna, and was awarded their annual prize, Hedenius-priset, in 2006. Ulvaeus describes himself as an atheist. He has appeared on several shows discussing his views about religion. + +Ulvaeus suffered from severe long-term memory loss. However, in a 2009 interview, he stated that reports of his memory loss were "hugely exaggerated". In a TV interview with Fredrik Skavlan, Ulvaeus said the memory loss pertained to episodic memory. He said that, for instance, he was not nostalgic for his days with ABBA: "It was good while it lasted." + +The Guardian called him Sweden's "highest-profile cash-free campaigner", explaining that "after his son was robbed several years ago, Ulvaeus became an evangelist for the electronic payment movement, claiming that cash was the primary cause of crime and that 'all activity in the black economy requires cash'". He has reportedly been living cash-free for more than a year, and ABBA The Museum has operated cash-free since it opened in May 2013. + +Tax vindication +The Swedish Tax Agency accused Björn Ulvaeus of failing to pay 90 million kronor (US$12.8 million) in back taxes for eight years ending in 2005. The agency claimed that he "laundered" his music royalty income through institutions in several foreign countries. Ulvaeus paid the taxes as a precautionary measure during the 2½-year dispute. In October 2008, the county administrative court decided the case in Ulvaeus' favour, ruling that he never owed any of the 90 million kronor. + +Discography + +Björn solo singles + 1968: "Raring" (Swedish version of "Honey")/"Vill Du Ha En Vän" + 1968: "Fröken Fredriksson" (Swedish version of "Harper Valley PTA")/"Vår Egen Sång" – (Polar POS 162) + 1969: "Saknar Du Något Min Kära" (Swedish version of "Where Do You Go To (My Lovely)?"/"Gömt Är Inte Glömt") + 1969: "Partaj-Aj-Aj-Aj"/"Kvinnan I Mitt Liv" + +Björn and Benny singles + 1970: "She's My Kind of Girl"/"Inga Theme" + 1970: "Hej Gamle Man!"/"Lycka" (Happiness) + 1971: "Hey, Musikant"/"Was die Liebe sagt" + 1971: "Det Kan Ingen Doktor Hjalpa" (It Can't Be Remedied by a Doctor)/"På Bröllop" + 1971: "Tänk Om Jorden Vore Ung" (If Only We Had The Time)/"Träskofolket" + 1972: "En Karusell" (Merry-Go-Round)/"Att Finnas Till" + 1972: "Love Has Its Ways"/"Rock 'N' Roll Band" (Benny & Björn 1st version) + +Björn and Benny albums + 1970: Lycka + 1984: Chess (concept album with Tim Rice) + 1986: Chess Pieces + 1988: Chess: Original Broadway Cast Recording + 1994: Chess in Concert + 1996: Kristina från Duvemåla + 1998: från Waterloo till Duvemåla + 1999: 16 favoriter ur Kristina från Duvemåla + 1999: Mamma Mia!

For the 2008 film version of Mamma Mia! and its 2018 sequel, Mamma Mia! Here We Go Again, he worked also as an executive producer. Since 2001, he has been active with his own band Benny Anderssons orkester. + +Early life +Göran Bror Benny Andersson was born 16 December 1946 in the Vasastan district of Stockholm to civil engineer Gösta Andersson (1912–1973) and his wife Laila (1920–1971). His sister Eva-Lis Andersson followed in 1948. Andersson's musical background comes from his father and grandfather (Efraim); they both enjoyed playing the accordion, and at six, Benny got his own. His father and grandfather taught him Swedish folk music, traditional music, and schlager. The first records Benny bought were "Du Bist Musik" by Italian schlager singer Caterina Valente and Elvis Presley's "Jailhouse Rock". He was especially impressed by the flip side, "Treat Me Nice", as this featured a piano. This variety of different kinds of music influenced him through the years. + +At ten, Andersson got his own piano and taught himself to play. He left school at 15 and began to perform at youth clubs. This is when he met his first girlfriend Christina Grönvall, with whom he had two children: Peter (born 1963) and Heléne (born 1965). In early 1964, Benny and Christina joined "Elverkets Spelmanslag" ("The Electricity Board Folk Music Group"); the name was a punning reference to their electric instruments. Their repertoire consisted mainly of instrumentals, including "Baby Elephant Walk"; he also wrote his first songs. + +Career + +Hep Stars (1964–1969) +In October 1964 he joined the Hep Stars as keyboardist and they made a breakthrough in March 1965 with their hit "Cadillac", eventually becoming the most celebrated of the Swedish 1960s pop bands. Andersson secured his place as the band's keyboardist and musical driving force as well as a teen idol. The band performed mostly covers of international hits, but Andersson soon started writing his own material, and gave the band the classic hits "No Response", "Sunny Girl", "Wedding", "Consolation", "It's Nice To Be Back" and "She Will Love You", among others. + +Before ABBA (1969–1972) +Andersson met Björn Ulvaeus in June 1966, and the two men started writing songs together, their first being "Isn't It Easy To Say", eventually recorded by the Hep Stars. He also had a fruitful songwriting collaboration with Lasse Berghagen, with whom he wrote several songs and submitted "Hej, Clown" for the 1969 Melodifestivalen – the Swedish Eurovision Song Festival finals. The song finished in second place. During this contest, he met vocalist Anni-Frid Lyngstad, and they soon became a couple. Around the same time, his songwriting companion Ulvaeus met vocalist Agnetha Fältskog. + +The personal relationships and Andersson and Ulvaeus' songwriting collaboration led quite naturally to the very close cooperation which the four friends had during the following years. Benny and Björn scored their first hits as songwriters in the spring of 1969: "Ljuva sextital" (a hit with Brita Borg) and "Speleman" (a hit for the Hep Stars). As the two couples began supporting each other during recording sessions, the sound of the women's voices convinced the songwriters to model their 'group' on various MOR acts such as Blue Mink, Middle of the Road and Sweet. Thus, ABBA came to life. + +ABBA (1972–1982) + +The group's breakthrough came with winning the Eurovision Song Contest for Sweden with "Waterloo" on 6 April 1974. During the next eight years, Andersson (together with Ulvaeus) wrote music for and produced eight studio albums with ABBA. The group achieved great success globally and scored a chain of No. 1 hits. + +With ABBA, Benny sang lead vocal on only one song – "Suzy-Hang-Around", from the Waterloo album. + +After ABBA: Chess, Kristina and Mamma Mia! (1983–present) +After ABBA, Andersson continued writing music with Ulvaeus. Their first project was the stage musical Chess, written with Tim Rice. The Chess concept album – with vocals by Elaine Paige, Barbara Dickson, Murray Head and Swedes Tommy Körberg and Björn Skifs – was released in October 1984, selling two million copies worldwide. The Paige/Dickson duet "I Know Him So Well" became a major UK No. 1 hit, and Murray Head's "One Night in Bangkok" gave Andersson/Ulvaeus a US No. 3 hit. + +Chess was staged in London's West End Prince Edward Theatre in May 1986 and received mixed to positive reviews, running for about three years. A revised staging on Broadway in April 1988 received poor reviews, running for two months. + +In 1985, Andersson produced and released an album with brother and sister Anders and Karin Glenmark, featuring new songs by Andersson/Ulvaeus. The duo named themselves Gemini, and a second album with more music by Björn and Benny was released in April 1987, containing the big hit "Mio My Mio"; also to be found on the soundtrack to the film Mio in the Land of Faraway, for which Andersson co-produced the music. + +In 1987, Andersson released his first solo album Klinga Mina Klockor ("Chime, My Bells"). All the music was written by and performed by himself on accordion, backed by the Orsa Spelmän (Orsa Folk Musicians) on fiddles. A second solo album followed: November 1989. + +In 1990, Andersson scored a Swedish No. 1 hit with "Lassie", sung by female cabaret group Ainbusk, for whom he also wrote the Svensktoppen hits "Älska Mig" and "Drömmarnas Golv". He decided to produce an album with Josefin Nilsson from this quartet, resulting in the 1993 English-language album Shapes, featuring ten new Andersson/Ulvaeus compositions. + +In 1992, he wrote the introduction melody for the European football championship, which was organised by Sweden that year. + +From the late 1980s, Andersson had worked on an idea for an epic Swedish language musical based on his affection for traditional folk music, and in October 1995, Kristina från Duvemåla premiered in Sweden. The musical was based on The Emigrants novels by Swedish writer Vilhelm Moberg. The musical ran successfully for almost five years, before closing in June 1999. An English-language version, simply titled Kristina, was staged in concert at Carnegie Hall in New York City for two nights in September 2009, yielding a live recording, and at the Royal Albert Hall for one night in April 2010. + +Andersson's next project was Mamma Mia!, a musical built around 24 of ABBA's songs, which has become a worldwide box-office blockbuster, with versions in several languages being played in many countries, including the UK (West End premiere in April 1999), Canada (Toronto premiere in 2000), the USA (Broadway premiere in 2001), and Sweden (Swedish language premiere in 2005). + +For the 2004 semi-final of the Eurovision Song Contest, staged in Istanbul thirty years after ABBA had won the contest in Brighton, Benny appeared briefly in a special comedy video made for the interval act, entitled "Our Last Video". Each of the four members of the group appeared briefly in cameo roles, as did others such as Cher and Rik Mayall. The video was not included in the official DVD release of the Eurovision Contest, but was issued as a separate DVD release. It was billed as the first time the four had worked together since the group split; however, Frida's appearance was filmed separately. + +A film version of Mamma Mia! premiered on 18 July 2008. In April/May 2007, Andersson worked on the film soundtrack, re-recording the ABBA songs with musicians from the original ABBA recording sessions. Mamma Mia! The Movie has become the most successful film musical of all time, and the biggest-selling DVD ever in the UK. + +Benny Anderssons Orkester (2001–present) +Andersson currently performs with his own band of 16 musicians, Benny Anderssons Orkester ("Benny Andersson's orchestra", BAO), with fellow Swedes Helen Sjöholm (of Kristina from Duvemåla) and Tommy Körberg (of Chess), with lyrics to new material sometimes written by Björn Ulvaeus. BAO has released five albums to huge success in Sweden, all containing hit singles. + +In 2009 BAO achieved a new record in Sweden on the Svensktoppen chart by staying there for 243 weeks with the song "Du är min man" ("You Are My Man"), sung by Sjöholm. + +New compositions (1984–present) + +Andersson composes primarily for his band BAO, with vocalists Sjöholm and Körberg, but he keeps his older material alive by re-visiting it, as in Mamma Mia! and the Swedish version of Chess. + +For a compilation album of the Glenmark duo Gemini, Andersson had Björn Ulvaeus write new Swedish lyrics for the re-recording of two songs from 1984 and 1987. + +Andersson and Ulvaeus have continuously been writing new material; most recently the two wrote seven songs for Andersson's BAO 2011 album O klang och jubeltid, performed as usual by vocalists Sjöholm, Körberg and Kalle Moraeus. In July 2009, BAO, now named "The Benny Andersson Band", released their first international record, the album The Story of a Heart. It was a compilation of 14 tracks from Andersson's five Swedish-language releases between 1987 and 2007, including five songs now recorded with lyrics by Ulvaeus in English, and the new title song premiered on BBC2's Ken Bruce Show. A Swedish-language version of the title track, "Sommaren Du Fick" ("The Summer You Got"), was released as a single in Sweden prior to the English version, with vocals by Helen Sjöholm. + +In the spring of 2009, Andersson also released a single recorded by the staff at his privately owned Stockholm hotel Hotel Rival, titled "2nd Best to None", accompanied by a video showing the staff at work. In 2008, Andersson and Ulvaeus wrote a song for Swedish singer Sissela Kyle, titled "Jag vill bli gammal" ("I Wanna Grow Old"), for her Stockholm stage show "Your Days Are Numbered", which was never recorded and released but did get a TV performance. Ulvaeus also contributed lyrics to ABBA's 1976 instrumental track "Arrival" for Sarah Brightman's cover version recorded for her 2008 album A Winter Symphony. New English lyrics have also been written for Andersson's 1999 song "Innan Gryningen" (then also named "Millennium Hymn"), with the new title "The Silence of the Dawn" for Barbara Dickson was performed live, but not yet recorded and released. In 2007, they wrote the new song "Han som har vunnit allt" ("He Who's Won It All") for actor and singer Anders Ekborg. + +Ulvaeus wrote English lyrics for two older songs from Andersson's solo albums I Walk with You Mama ("Stockholm by Night", 1989) and After the Rain ("Efter regnet", 1987) for opera singer Anne Sofie Von Otter, for her Andersson tribute album I Let the Music Speak. Barbara Dickson recorded an Ulvaeus and Andersson song called "The Day The Wall Came Tumbling Down"; the song eventually was released by Australian Mamma Mia! musical star Anne Wood's album of ABBA covers, Divine Discontent. As of October 2012, Ulvaeus had mentioned writing new material with Andersson for a BAO Christmas release (also mentioned as a BAO box), and Andersson is busy writing music for a Swedish language obscure musical, Hjälp Sökes ("Help is Wanted") together with Kristina Lugn and Lars Rudolfsson, premiering 8 February 2013. + +Andersson has also written music for a documentary film about Olof Palme, re-recording the track "Sorgmarch" from his last album as a theme throughout the film. +The song "Kärlekens Tid", recorded 2004 by Helen Sjöholm with BAO, has also been performed in concert in English (lyrics by Ylva Eggehorn) by opera baritone Bryn Terfel. +On 15 April 2013, it was officially announced by the EBU and the SVT that Andersson, along with Ulvaeus and the late Stockholm based DJ and record producer Avicii, had composed the anthem for the 2013 Eurovision Song Contest. The song was performed for the first time in the Final on 18 May. + +A new album of Andersson compositions presented in a choral style was released on 18 September 2015. "Kärlekens Tid" was produced in Andersson's Mono Music studio, under the direction of choirmaster Gustaf Sjökvist, who died before the album's release. Gustaf Sjökvists Choir, conducted by Cecilia Rydinger Alin, performed two concerts at Skeppsholmen on 20 September, featuring Benny Andersson on piano. The album includes songs in Swedish and English from a range of Andersson's projects, such as Chess, Kristina and BAO. + +In November 2018, Deutsche Grammophon released Piano, a collection of ABBA tunes, tunes from Chess and original compositions all played by Andersson on solo piano. + +Andersson reunited with ABBA in 2018. On 2 September 2021, via YouTube livestream, ABBA announced their upcoming virtual concert residency "ABBA Voyage", as well as the imminent release of an eponymous album, recorded between 2017 and 2021. The new record, their first studio album in 40 years, features ten tracks, including "I Still Have Faith In You" and "Don't Shut Me Down", which also were first shown in the aforementioned livestream event and released as a double A-side single. On 5 November 2021, the Voyage album was released worldwide. On 27 May 2022, ABBA Voyage opened in a purpose-built venue named the ABBA Arena at the Queen Elizabeth Olympic Park in London. + +Film music +Andersson has written music to several films for screen and television; the first attempt in the early 1970s for the Swedish erotica movie The Seduction of Inga; the film was not a success, but the 'Björn & Benny' single "She's My Kind of Girl" surprised the composers by being released in Japan and becoming a Top 10 hit (the song renamed in Japan as "The Little Girl of the Cold Wind"). + +In 1987, Andersson wrote music and co-produced the soundtrack with Anders Eljas for the film Mio in the Land of Faraway, based on Swedish author Astrid Lindgrens Mio, My Son. The title song became a huge hit in Sweden for Gemini. + +In 2000, he wrote the music for fellow Swede (no relation) Roy Andersson's film Songs from the Second Floor (the music later re-recorded, featuring new lyrics, with BAO! with vocals by Helen Sjöholm). He also wrote the theme for Roy Andersson's next film, You, the Living, from 2007. + +Andersson worked on the film adaptation of Mamma Mia!. He also wrote the film score for the 2012 documentary Palme about Swedish prime minister Olof Palme. He later won a Guldbagge Award for Best Original Score, for that film at the 48th Guldbagge Awards. + +Awards +Together with Ulvaeus, Andersson was nominated for a Drama Desk Award in a category "Outstanding Music" (for the musical Chess), and for a Tony Award in a category "Best Orchestrations" (for musical Mamma Mia!). Original cast recordings of both musicals were nominated for a Grammy Award. Andersson/Ulvaeus also won a Touring Broadway Award for the musical "Mamma Mia" (best score). + +During his post-ABBA career Andersson won four Swedish Grammis awards, and together with Ulvaeus received the "Special International" Ivor Novello award from 'The British Academy of Composers and Songwriters', twice "The Music Export Prize" from the Swedish Ministry of Industry and Trade (2008), as well as the "Lifetime Achievement" award from the Swedish Music Publishers Association (SMFF). In 2002, Andersson was given an honorary professorship by the Swedish Government for his "ability to create high-class music reaching people around the world". + +In 2007, he was elected a member of Royal Swedish Academy of Music, and in 2008 received an Honorary Doctorate from the Stockholm University Faculty of Humanities for contributing importantly both to the preservation and the growth of the Swedish folk music tradition. + +On 15 March 2010, Andersson appeared on stage in New York with former wife Anni-Frid Lyngstad to accept ABBA's award of induction into the Rock and Roll Hall of Fame. During his acceptance speech he reflected on the important influence of traditional European music and the melancholy of the Swedish soul on ABBA's brand of pop music. "If you live in a country like Sweden, with five, six months of snow, and the sun disappears totally for like two months, that would be reflected in the work of artists," he said. "It's definitely in the Swedish folk music, you can hear it in the Russian folk songs, you can hear in the music from Jean Sibelius or Edvard Grieg from Norway, you can see it in the eyes of Greta Garbo and you can hear it in the voice of Jussi Björling. And you can hear in the sound of Frida and Agnetha on some of our songs too." + +In 2012, he received an Honorary Doctorate of Philosophy from the Luleå Tekniska Universitet Faculty of Humanities and Social Sciences. + +Andersson won the Swedish "Guldbaggen" award in 2012 as composer of the music for the film "Palme". + +For his album Piano he received the Opus Klassik award in 2018. + +Personal life + +Andersson was engaged to Christina Grönvall. In 1963, they had a son, Peter, and in 1965, a daughter, Heléne. Both children were given their mother's surname. The couple split in 1966 and Christina kept custody of the children as Andersson was then at the peak of his Hep Stars' success. In the 1990s, Peter formed One More Time, a group that enjoyed European success with the ABBA-like "Highland" and, later, as Sweden's entry to the Eurovision Song Contest 1996. + +Andersson was in a relationship with Anni-Frid Lyngstad of ABBA for about 11 years, from 1969 till 1980. They married on 6 October 1978, but separated on 26 November 1980 and divorced in 1981. + +He married Swedish TV presenter Mona Nörklit in 1981 and had a son, Ludvig (born January 1982), who has since followed in his father's footsteps in forming his own band. Ludvig is also one of the producers of the concert residency ABBA Voyage. + +Andersson was an alcoholic through much of his adult life. He has remained a teetotaler since 2001. Andersson did not disclose the extent of his substance abuse problems until a 2011 interview, at which point he had maintained nearly a decade of sobriety. + +Discography + +Also appears on +Beginner's Guide to Scandinavia (3CD, Nascente 2011) + +See also + +List of Swedes in music + +References + +External links + + Deutsche Grammophon page on Benny Andersson + BBC Radio 3 New Generation Artists page + icethesite (Benny Andersson and Björn Ulvaeus news site) + The Hep Stars International Official website (Benny before ABBA) + Chronology: Benny Andersson + Official ABBA site + +1946 births +Living people +Musicians from Stockholm +ABBA members +Members of the Royal Swedish Academy of Music +Swedish accordionists +Swedish keyboardists +Swedish pianists +Swedish male songwriters +20th-century Swedish male singers +Swedish musical theatre composers +Swedish film score composers +Georges Delerue Award winners +Swedish pop pianists +Eurodisco musicians +Ivor Novello Award winners +Swedish feminists +Male feminists +Feminist musicians +Eurovision Song Contest winners +Best Original Score Guldbagge Award winners +21st-century Swedish male singers +Acoustic guitarists +Swedish organists +Male organists +21st-century accordionists +Male pianists +21st-century organists +Male film score composers +Deutsche Grammophon artists +Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to . It employs UHF radio waves in the ISM bands, from 2.402GHz to 2.48GHz. It is mainly used as an alternative to wire connections, to exchange files between nearby portable devices and connect cell phones and music players with wireless headphones. + +Bluetooth is managed by the Bluetooth Special Interest Group (SIG), which has more than 35,000 member companies in the areas of telecommunication, computing, networking, and consumer electronics. The IEEE standardized Bluetooth as IEEE 802.15.1, but no longer maintains the standard. The Bluetooth SIG oversees development of the specification, manages the qualification program, and protects the trademarks. A manufacturer must meet Bluetooth SIG standards to market it as a Bluetooth device. A network of patents apply to the technology, which are licensed to individual qualifying devices. , 4.7 billion Bluetooth integrated circuit chips are shipped annually. + +Etymology +The name "Bluetooth" was proposed in 1997 by Jim Kardach of Intel, one of the founders of the Bluetooth SIG. The name was inspired by a conversation with Sven Mattisson who related Scandinavian history through tales from Frans G. Bengtsson's The Long Ships, a historical novel about Vikings and the 10th-century Danish king Harald Bluetooth. Upon discovering a picture of the runestone of Harald Bluetooth in the book A History of the Vikings by Gwyn Jones, Kardach proposed Bluetooth as the codename for the short-range wireless program which is now called Bluetooth. + +According to Bluetooth's official website, + +Bluetooth is the Anglicised version of the Scandinavian Blåtand/Blåtann (or in Old Norse blátǫnn). It was the epithet of King Harald Bluetooth, who united the disparate +Danish tribes into a single kingdom; Kardach chose the name to imply that Bluetooth similarly unites communication protocols. + +The Bluetooth logo is a bind rune merging the Younger Futhark runes  (ᚼ, Hagall) and  (ᛒ, Bjarkan), Harald's initials. + +History + +The development of the "short-link" radio technology, later named Bluetooth, was initiated in 1989 by Nils Rydbeck, CTO at Ericsson Mobile in Lund, Sweden. The purpose was to develop wireless headsets, according to two inventions by Johan Ullman, and . Nils Rydbeck tasked Tord Wingren with specifying and Dutchman Jaap Haartsen and Sven Mattisson with developing. Both were working for Ericsson in Lund. Principal design and development began in 1994 and by 1997 the team had a workable solution. From 1997 Örjan Johansson became the project leader and propelled the technology and standardization. + +In 1997, Adalio Sanchez, then head of IBM ThinkPad product R&D, approached Nils Rydbeck about collaborating on integrating a mobile phone into a ThinkPad notebook. The two assigned engineers from Ericsson and IBM studied the idea. The conclusion was that power consumption on cellphone technology at that time was too high to allow viable integration into a notebook and still achieve adequate battery life. Instead, the two companies agreed to integrate Ericsson's short-link technology on both a ThinkPad notebook and an Ericsson phone to accomplish the goal. + +Since neither IBM ThinkPad notebooks nor Ericsson phones were the market share leaders in their respective markets at that time, Adalio Sanchez and Nils Rydbeck agreed to make the short-link technology an open industry standard to permit each player maximum market access. Ericsson contributed the short-link radio technology, and IBM contributed patents around the logical layer. Adalio Sanchez of IBM then recruited Stephen Nachtsheim of Intel to join and then Intel also recruited Toshiba and Nokia. In May 1998, the Bluetooth SIG was launched with IBM and Ericsson as the founding signatories and a total of five members: Ericsson, Intel, Nokia, Toshiba, and IBM. + +The first Bluetooth device was revealed in 1999. It was a hands-free mobile headset that earned the "Best of show Technology Award" at COMDEX. The first Bluetooth mobile phone was the Ericsson T36, but it was the revised Ericsson model T39 that actually made it to store shelves in 2001. In parallel, IBM introduced the IBM ThinkPad A30 in October 2001 which was the first notebook with integrated Bluetooth. + +Bluetooth's early incorporation into consumer electronics products continued at Vosi Technologies in Costa Mesa, California, initially overseen by founding members Bejan Amini and Tom Davidson. Vosi Technologies had been created by real estate developer Ivano Stegmenga, with United States Patent 608507, for communication between a cellular phone and a vehicle's audio system. At the time, Sony/Ericsson had only a minor market share in the cellular phone market, which was dominated in the US by Nokia and Motorola. Due to ongoing negotiations for an intended licensing agreement with Motorola beginning in the late 1990s, Vosi could not publicly disclose the intention, integration, and initial development of other enabled devices which were to be the first "Smart Home" internet connected devices. + +Vosi needed a means for the system to communicate without a wired connection from the vehicle to the other devices in the network. Bluetooth was chosen, since Wi-Fi was not yet readily available or supported in the public market. Vosi had begun to develop the Vosi Cello integrated vehicular system and some other internet connected devices, one of which was intended to be a table-top device named the Vosi Symphony, networked with Bluetooth. Through the negotiations with Motorola, Vosi introduced and disclosed its intent to integrate Bluetooth in its devices. In the early 2000s a legal battle ensued between Vosi and Motorola, which indefinitely suspended release of the devices. Later, Motorola implemented it in their devices which initiated the significant propagation of Bluetooth in the public market due to its large market share at the time. + +In 2012, Jaap Haartsen was nominated by the European Patent Office for the European Inventor Award. + +Implementation +Bluetooth operates at frequencies between 2.402 and 2.480GHz, or 2.400 and 2.4835GHz, including guard bands 2MHz wide at the bottom end and 3.5MHz wide at the top. This is in the globally unlicensed (but not unregulated) industrial, scientific and medical (ISM) 2.4GHz short-range radio frequency band. Bluetooth uses a radio technology called frequency-hopping spread spectrum. Bluetooth divides transmitted data into packets, and transmits each packet on one of 79 designated Bluetooth channels. Each channel has a bandwidth of 1MHz. It usually performs 1600hops per second, with adaptive frequency-hopping (AFH) enabled. Bluetooth Low Energy uses 2MHz spacing, which accommodates 40 channels. + +Originally, Gaussian frequency-shift keying (GFSK) modulation was the only modulation scheme available. Since the introduction of Bluetooth 2.0+EDR, π/4-DQPSK (differential quadrature phase-shift keying) and 8-DPSK modulation may also be used between compatible devices. Devices functioning with GFSK are said to be operating in basic rate (BR) mode, where an instantaneous bit rate of 1Mbit/s is possible. The term Enhanced Data Rate (EDR) is used to describe π/4-DPSK (EDR2) and 8-DPSK (EDR3) schemes, each giving 2 and 3Mbit/s respectively. The combination of these (BR and EDR) modes in Bluetooth radio technology is classified as a BR/EDR radio. + +In 2019, Apple published an extension called HDR which supports data rates of 4 (HDR4) and 8 (HDR8) Mbit/s using π/4-DQPSK modulation on 4 MHz channels with forward error correction (FEC). + +Bluetooth is a packet-based protocol with a master/slave architecture. One master may communicate with up to seven slaves in a piconet. All devices within a given piconet use the clock provided by the master as the base for packet exchange. The master clock ticks with a period of 312.5μs, two clock ticks then make up a slot of 625µs, and two slots make up a slot pair of 1250µs. In the simple case of single-slot packets, the master transmits in even slots and receives in odd slots. The slave, conversely, receives in even slots and transmits in odd slots. Packets may be 1, 3, or 5 slots long, but in all cases, the master's transmission begins in even slots and the slave's in odd slots. + +The above excludes Bluetooth Low Energy, introduced in the 4.0 specification, which uses the same spectrum but somewhat differently. + +Communication and connection +A master BR/EDR Bluetooth device can communicate with a maximum of seven devices in a piconet (an ad hoc computer network using Bluetooth technology), though not all devices reach this maximum. The devices can switch roles, by agreement, and the slave can become the master (for example, a headset initiating a connection to a phone necessarily begins as master—as an initiator of the connection—but may subsequently operate as the slave). + +The Bluetooth Core Specification provides for the connection of two or more piconets to form a scatternet, in which certain devices simultaneously play the master/leader role in one piconet and the slave role in another. + +At any given time, data can be transferred between the master and one other device (except for the little-used broadcast mode). The master chooses which slave device to address; typically, it switches rapidly from one device to another in a round-robin fashion. Since it is the master that chooses which slave to address, whereas a slave is (in theory) supposed to listen in each receive slot, being a master is a lighter burden than being a slave. Being a master of seven slaves is possible; being a slave of more than one master is possible. The specification is vague as to required behavior in scatternets. + +Uses +Bluetooth is a standard wire-replacement communications protocol primarily designed for low power consumption, with a short range based on low-cost transceiver microchips in each device. Because the devices use a radio (broadcast) communications system, they do not have to be in visual line of sight of each other; however, a quasi optical wireless path must be viable. + +Bluetooth Classes and power use + +Historically, the Bluetooth range was defined by the radio class, with a lower class (and higher output power) having larger range. The actual range achieved by a given link will depend on the qualities of the devices at both ends of the link, as well as the air and obstacles in between. The primary hardware attributes affecting range are the data rate, protocol (Bluetooth Classic or Bluetooth Low Energy), the transmitter power, the receiver sensitivity, and the gain of both antennas. + +The effective range varies depending on propagation conditions, material coverage, production sample variations, antenna configurations and battery conditions. Most Bluetooth applications are for indoor conditions, where attenuation of walls and signal fading due to signal reflections make the range far lower than specified line-of-sight ranges of the Bluetooth products. + +Most Bluetooth applications are battery-powered Class 2 devices, with little difference in range whether the other end of the link is a Class 1 or Class 2 device as the lower-powered device tends to set the range limit. In some cases the effective range of the data link can be extended when a Class 2 device is connecting to a Class 1 transceiver with both higher sensitivity and transmission power than a typical Class 2 device. Mostly, however, the Class 1 devices have a similar sensitivity to Class 2 devices. Connecting two Class 1 devices with both high sensitivity and high power can allow ranges far in excess of the typical 100m, depending on the throughput required by the application. Some such devices allow open field ranges of up to 1 km and beyond between two similar devices without exceeding legal emission limits. + +Bluetooth profile + +To use Bluetooth wireless technology, a device must be able to interpret certain Bluetooth profiles. +For example, + + The Headset Profile (HSP) connects headphones and earbuds to a cell phone or laptop. + + The Health Device Profile (HDP) can connect a cell phone to a digital thermometer, or a heart rate detector. + + The Video Distribution Profile (VDP) sends a video stream from a video camera to a TV screen or a recording device. + +Profiles are definitions of possible applications and specify general behaviors that Bluetooth-enabled devices use to communicate with other Bluetooth devices. These profiles include settings to parameterize and to control the communication from the start. Adherence to profiles saves the time for transmitting the parameters anew before the bi-directional link becomes effective. There are a wide range of Bluetooth profiles that describe many different types of applications or use cases for devices. + +List of applications + + Wireless control and communication between a mobile phone and a handsfree headset. This was one of the earliest applications to become popular. + Wireless control of audio and communication functions between a mobile phone and a Bluetooth compatible car stereo system (and sometimes between the SIM card and the car phone). +Wireless communication between a smartphone and a smart lock for unlocking doors. + Wireless control of and communication with iOS and Android device phones, tablets and portable wireless speakers. + Wireless Bluetooth headset and intercom. Idiomatically, a headset is sometimes called "a Bluetooth". + Wireless streaming of audio to headphones with or without communication capabilities. + Wireless streaming of data collected by Bluetooth-enabled fitness devices to phone or PC. + Wireless networking between PCs in a confined space and where little bandwidth is required. + Wireless communication with PC input and output devices, the most common being the mouse, keyboard and printer. + Transfer of files, contact details, calendar appointments, and reminders between devices with OBEX and sharing directories via FTP. + Triggering the camera shutter of a smartphone using a Bluetooth controlled selfie stick. + Replacement of previous wired RS-232 serial communications in test equipment, GPS receivers, medical equipment, bar code scanners, and traffic control devices. + For controls where infrared was often used. + For low bandwidth applications where higher USB bandwidth is not required and cable-free connection desired. + Sending small advertisements from Bluetooth-enabled advertising hoardings to other, discoverable, Bluetooth devices. + Wireless bridge between two Industrial Ethernet (e.g., PROFINET) networks. + Game consoles have been using Bluetooth as a wireless communications protocol for peripherals since the seventh generation, including Nintendo's Wii and Sony's PlayStation 3 which use Bluetooth for their respective controllers. + Dial-up internet access on personal computers or PDAs using a data-capable mobile phone as a wireless modem. + Short-range transmission of health sensor data from medical devices to mobile phone, set-top box or dedicated telehealth devices. + Allowing a DECT phone to ring and answer calls on behalf of a nearby mobile phone. +Real-time location systems (RTLS) are used to track and identify the location of objects in real time using "Nodes" or "tags" attached to, or embedded in, the objects tracked, and "Readers" that receive and process the wireless signals from these tags to determine their locations. + Personal security application on mobile phones for prevention of theft or loss of items. The protected item has a Bluetooth marker (e.g., a tag) that is in constant communication with the phone. If the connection is broken (the marker is out of range of the phone) then an alarm is raised. This can also be used as a man overboard alarm. + Calgary, Alberta, Canada's Roads Traffic division uses data collected from travelers' Bluetooth devices to predict travel times and road congestion for motorists. + Wireless transmission of audio (a more reliable alternative to FM transmitters) + Live video streaming to the visual cortical implant device by Nabeel Fattah in Newcastle university 2017. + Connection of motion controllers to a PC when using VR headsets + +Bluetooth vs Wi-Fi (IEEE 802.11) +Bluetooth and Wi-Fi (Wi-Fi is the brand name for products using IEEE 802.11 standards) have some similar applications: setting up networks, printing, or transferring files. Wi-Fi is intended as a replacement for high-speed cabling for general local area network access in work areas or home. This category of applications is sometimes called wireless local area networks (WLAN). Bluetooth was intended for portable equipment and its applications. The category of applications is outlined as the wireless personal area network (WPAN). Bluetooth is a replacement for cabling in various personally carried applications in any setting and also works for fixed location applications such as smart energy functionality in the home (thermostats, etc.). + +Wi-Fi and Bluetooth are to some extent complementary in their applications and usage. Wi-Fi is usually access point-centered, with an asymmetrical client-server connection with all traffic routed through the access point, while Bluetooth is usually symmetrical, between two Bluetooth devices. Bluetooth serves well in simple applications where two devices need to connect with a minimal configuration like a button press, as in headsets and speakers. + +Devices + +Bluetooth exists in numerous products such as telephones, speakers, tablets, media players, robotics systems, laptops, and game console equipment as well as some high definition headsets, modems, hearing aids and even watches. Given the variety of devices which use Bluetooth, coupled with the contemporary deprecation of headphone jacks by Apple, Google, and other companies, and the lack of regulation by the FCC, the technology is prone to interference. Nonetheless, Bluetooth is useful when transferring information between two or more devices that are near each other in low-bandwidth situations. Bluetooth is commonly used to transfer sound data with telephones (i.e., with a Bluetooth headset) or byte data with hand-held computers (transferring files). + +Bluetooth protocols simplify the discovery and setup of services between devices. Bluetooth devices can advertise all of the services they provide. This makes using services easier, because more of the security, network address and permission configuration can be automated than with many other network types. + +Computer requirements + +A personal computer that does not have embedded Bluetooth can use a Bluetooth adapter that enables the PC to communicate with Bluetooth devices. While some desktop computers and most recent laptops come with a built-in Bluetooth radio, others require an external adapter, typically in the form of a small USB "dongle." + +Unlike its predecessor, IrDA, which requires a separate adapter for each device, Bluetooth lets multiple devices communicate with a computer over a single adapter. + +Operating system implementation + +For Microsoft platforms, Windows XP Service Pack 2 and SP3 releases work natively with Bluetooth v1.1, v2.0 and v2.0+EDR. Previous versions required users to install their Bluetooth adapter's own drivers, which were not directly supported by Microsoft. Microsoft's own Bluetooth dongles (packaged with their Bluetooth computer devices) have no external drivers and thus require at least Windows XP Service Pack 2. Windows Vista RTM/SP1 with the Feature Pack for Wireless or Windows Vista SP2 work with Bluetooth v2.1+EDR. Windows 7 works with Bluetooth v2.1+EDR and Extended Inquiry Response (EIR). +The Windows XP and Windows Vista/Windows 7 Bluetooth stacks support the following Bluetooth profiles natively: PAN, SPP, DUN, HID, HCRP. The Windows XP stack can be replaced by a third party stack that supports more profiles or newer Bluetooth versions. The Windows Vista/Windows 7 Bluetooth stack supports vendor-supplied additional profiles without requiring that the Microsoft stack be replaced. Windows 8 and later support Bluetooth Low Energy (BLE). It is generally recommended to install the latest vendor driver and its associated stack to be able to use the Bluetooth device at its fullest extent. + +Apple products have worked with Bluetooth since Mac OSX v10.2, which was released in 2002. + +Linux has two popular Bluetooth stacks, BlueZ and Fluoride. The BlueZ stack is included with most Linux kernels and was originally developed by Qualcomm. Fluoride, earlier known as Bluedroid is included in Android OS and was originally developed by Broadcom. +There is also Affix stack, developed by Nokia. It was once popular, but has not been updated since 2005. + +FreeBSD has included Bluetooth since its v5.0 release, implemented through netgraph. + +NetBSD has included Bluetooth since its v4.0 release. Its Bluetooth stack was ported to OpenBSD as well, however OpenBSD later removed it as unmaintained. + +DragonFly BSD has had NetBSD's Bluetooth implementation since 1.11 (2008). A netgraph-based implementation from FreeBSD has also been available in the tree, possibly disabled until 2014-11-15, and may require more work. + +Specifications and features +The specifications were formalized by the Bluetooth Special Interest Group (SIG) and formally announced on 20 May 1998. In 2014 it had a membership of over 30,000 companies worldwide. It was established by Ericsson, IBM, Intel, Nokia and Toshiba, and later joined by many other companies. + +All versions of the Bluetooth standards support backwards compatibility. That lets the latest standard cover all older versions. + +The Bluetooth Core Specification Working Group (CSWG) produces mainly 4 kinds of specifications: + The Bluetooth Core Specification, release cycle is typically a few years in between + Core Specification Addendum (CSA), release cycle can be as tight as a few times per year + Core Specification Supplements (CSS), can be released very quickly + Errata (Available with a user account: Errata login) + +Bluetooth 1.0 and 1.0B + + Products were not interoperable + Anonymity was not possible, preventing certain services from using Bluetooth environments + +Bluetooth 1.1 + Ratified as IEEE Standard 802.15.1–2002 + Many errors found in the v1.0B specifications were fixed. + Added possibility of non-encrypted channels. + Received signal strength indicator (RSSI). + +Bluetooth 1.2 +Major enhancements include: + Faster connection and discovery + Adaptive frequency-hopping spread spectrum (AFH), which improves resistance to radio frequency interference by avoiding the use of crowded frequencies in the hopping sequence. + Higher transmission speeds in practice than in v1.1, up to 721 kbit/s. + Extended Synchronous Connections (eSCO), which improve voice quality of audio links by allowing retransmissions of corrupted packets, and may optionally increase audio latency to provide better concurrent data transfer. + Host Controller Interface (HCI) operation with three-wire UART. + Ratified as IEEE Standard 802.15.1–2005 + Introduced flow control and retransmission modes for . + +Bluetooth 2.0 + EDR +This version of the Bluetooth Core Specification was released before 2005. The main difference is the introduction of an Enhanced Data Rate (EDR) for faster data transfer. The bit rate of EDR is 3Mbit/s, although the maximum data transfer rate (allowing for inter-packet time and acknowledgements) is 2.1Mbit/s. EDR uses a combination of GFSK and phase-shift keying modulation (PSK) with two variants, π/4-DQPSK and 8-DPSK. EDR can provide a lower power consumption through a reduced duty cycle. + +The specification is published as Bluetooth v2.0 + EDR, which implies that EDR is an optional feature. Aside from EDR, the v2.0 specification contains other minor improvements, and products may claim compliance to "Bluetooth v2.0" without supporting the higher data rate. At least one commercial device states "Bluetooth v2.0 without EDR" on its data sheet. + +Bluetooth 2.1 + EDR +Bluetooth Core Specification version 2.1 + EDR was adopted by the Bluetooth SIG on 26 July 2007. + +The headline feature of v2.1 is secure simple pairing (SSP): this improves the pairing experience for Bluetooth devices, while increasing the use and strength of security. + +Version 2.1 allows various other improvements, including extended inquiry response (EIR), which provides more information during the inquiry procedure to allow better filtering of devices before connection; and sniff subrating, which reduces the power consumption in low-power mode. + +Bluetooth 3.0 + HS +Version 3.0 + HS of the Bluetooth Core Specification was adopted by the Bluetooth SIG on 21 April 2009. Bluetooth v3.0 + HS provides theoretical data transfer speeds of up to 24 Mbit/s, though not over the Bluetooth link itself. Instead, the Bluetooth link is used for negotiation and establishment, and the high data rate traffic is carried over a colocated 802.11 link. + +The main new feature is (Alternative MAC/PHY), the addition of 802.11 as a high-speed transport. The high-speed part of the specification is not mandatory, and hence only devices that display the "+HS" logo actually support Bluetooth over 802.11 high-speed data transfer. A Bluetooth v3.0 device without the "+HS" suffix is only required to support features introduced in Core Specification version 3.0 or earlier Core Specification Addendum 1. + + L2CAP Enhanced modes Enhanced Retransmission Mode (ERTM) implements reliable L2CAP channel, while Streaming Mode (SM) implements unreliable channel with no retransmission or flow control. Introduced in Core Specification Addendum 1. + Alternative MAC/PHY Enables the use of alternative MAC and PHYs for transporting Bluetooth profile data. The Bluetooth radio is still used for device discovery, initial connection and profile configuration. However, when large quantities of data must be sent, the high-speed alternative MAC PHY 802.11 (typically associated with Wi-Fi) transports the data. This means that Bluetooth uses proven low power connection models when the system is idle, and the faster radio when it must send large quantities of data. AMP links require enhanced L2CAP modes. + Unicast Connectionless Data Permits sending service data without establishing an explicit L2CAP channel. It is intended for use by applications that require low latency between user action and reconnection/transmission of data. This is only appropriate for small amounts of data. + Enhanced Power Control Updates the power control feature to remove the open loop power control, and also to clarify ambiguities in power control introduced by the new modulation schemes added for EDR. Enhanced power control removes the ambiguities by specifying the behavior that is expected. The feature also adds closed loop power control, meaning RSSI filtering can start as the response is received. Additionally, a "go straight to maximum power" request has been introduced. This is expected to deal with the headset link loss issue typically observed when a user puts their phone into a pocket on the opposite side to the headset. + +Ultra-wideband +The high-speed (AMP) feature of Bluetooth v3.0 was originally intended for UWB, but the WiMedia Alliance, the body responsible for the flavor of UWB intended for Bluetooth, announced in March 2009 that it was disbanding, and ultimately UWB was omitted from the Core v3.0 specification. + +On 16 March 2009, the WiMedia Alliance announced it was entering into technology transfer agreements for the WiMedia Ultra-wideband (UWB) specifications. WiMedia has transferred all current and future specifications, including work on future high-speed and power-optimized implementations, to the Bluetooth Special Interest Group (SIG), Wireless USB Promoter Group and the USB Implementers Forum. After successful completion of the technology transfer, marketing, and related administrative items, the WiMedia Alliance ceased operations. + +In October 2009, the Bluetooth Special Interest Group suspended development of UWB as part of the alternative MAC/PHY, Bluetooth v3.0 + HS solution. A small, but significant, number of former WiMedia members had not and would not sign up to the necessary agreements for the IP transfer. As of 2009, the Bluetooth SIG was in the process of evaluating other options for its longer term roadmap. + +Bluetooth 4.0 + +The Bluetooth SIG completed the Bluetooth Core Specification version 4.0 (called Bluetooth Smart) and has been adopted . It includes Classic Bluetooth, Bluetooth high speed and Bluetooth Low Energy (BLE) protocols. Bluetooth high speed is based on Wi-Fi, and Classic Bluetooth consists of legacy Bluetooth protocols. + +Bluetooth Low Energy, previously known as Wibree, is a subset of Bluetooth v4.0 with an entirely new protocol stack for rapid build-up of simple links. As an alternative to the Bluetooth standard protocols that were introduced in Bluetooth v1.0 to v3.0, it is aimed at very low power applications powered by a coin cell. Chip designs allow for two types of implementation, dual-mode, single-mode and enhanced past versions. The provisional names Wibree and Bluetooth ULP (Ultra Low Power) were abandoned and the BLE name was used for a while. In late 2011, new logos "Bluetooth Smart Ready" for hosts and "Bluetooth Smart" for sensors were introduced as the general-public face of BLE. + +Compared to Classic Bluetooth, Bluetooth Low Energy is intended to provide considerably reduced power consumption and cost while maintaining a similar communication range. In terms of lengthening the battery life of Bluetooth devices, represents a significant progression. + + In a single-mode implementation, only the low energy protocol stack is implemented. Dialog Semiconductor, STMicroelectronics, AMICCOM, CSR, Nordic Semiconductor and Texas Instruments have released single mode Bluetooth Low Energy solutions. + In a dual-mode implementation, Bluetooth Smart functionality is integrated into an existing Classic Bluetooth controller. , the following semiconductor companies have announced the availability of chips meeting the standard: Qualcomm-Atheros, CSR, Broadcom and Texas Instruments. The compliant architecture shares all of Classic Bluetooth's existing radio and functionality resulting in a negligible cost increase compared to Classic Bluetooth. + +Cost-reduced single-mode chips, which enable highly integrated and compact devices, feature a lightweight Link Layer providing ultra-low power idle mode operation, simple device discovery, and reliable point-to-multipoint data transfer with advanced power-save and secure encrypted connections at the lowest possible cost. + +General improvements in version 4.0 include the changes necessary to facilitate BLE modes, as well the Generic Attribute Profile (GATT) and Security Manager (SM) services with AES Encryption. + +Core Specification Addendum 2 was unveiled in December 2011; it contains improvements to the audio Host Controller Interface and to the High Speed (802.11) Protocol Adaptation Layer. + +Core Specification Addendum 3 revision 2 has an adoption date of 24 July 2012. + +Core Specification Addendum 4 has an adoption date of 12 February 2013. + +Bluetooth 4.1 +The Bluetooth SIG announced formal adoption of the Bluetooth v4.1 specification on 4 December 2013. This specification is an incremental software update to Bluetooth Specification v4.0, and not a hardware update. The update incorporates Bluetooth Core Specification Addenda (CSA 1, 2, 3 & 4) and adds new features that improve consumer usability. These include increased co-existence support for LTE, bulk data exchange rates—and aid developer innovation by allowing devices to support multiple roles simultaneously. + +New features of this specification include: + Mobile wireless service coexistence signaling + Train nudging and generalized interlaced scanning + Low Duty Cycle Directed Advertising + L2CAP connection-oriented and dedicated channels with credit-based flow control + Dual Mode and Topology + LE Link Layer Topology + 802.11n PAL + Audio architecture updates for Wide Band Speech + Fast data advertising interval + Limited discovery time +Notice that some features were already available in a Core Specification Addendum (CSA) before the release of v4.1. + +Bluetooth 4.2 +Released on 2 December 2014, it introduces features for the Internet of things. + +The major areas of improvement are: + Low Energy Secure Connection with Data Packet Length Extension + Link Layer Privacy with Extended Scanner Filter Policies + Internet Protocol Support Profile (IPSP) version 6 ready for Bluetooth Smart things to support connected home +Older Bluetooth hardware may receive 4.2 features such as Data Packet Length Extension and improved privacy via firmware updates. + +Bluetooth 5 +The Bluetooth SIG released Bluetooth 5 on 6 December 2016. Its new features are mainly focused on new Internet of Things technology. Sony was the first to announce Bluetooth 5.0 support with its Xperia XZ Premium in Feb 2017 during the Mobile World Congress 2017. The Samsung Galaxy S8 launched with Bluetooth 5 support in April 2017. In September 2017, the iPhone 8, 8 Plus and iPhone X launched with Bluetooth 5 support as well. Apple also integrated Bluetooth 5 in its new HomePod offering released on 9 February 2018. Marketing drops the point number; so that it is just "Bluetooth 5" (unlike Bluetooth 4.0); the change is for the sake of "Simplifying our marketing, communicating user benefits more effectively and making it easier to signal significant technology updates to the market." + +Bluetooth 5 provides, for BLE, options that can double the speed (2Mbit/s burst) at the expense of range, or provide up to four times the range at the expense of data rate. The increase in transmissions could be important for Internet of Things devices, where many nodes connect throughout a whole house. Bluetooth 5 increases capacity of connectionless services such as location-relevant navigation of low-energy Bluetooth connections. + +The major areas of improvement are: + Slot Availability Mask (SAM) + 2 Mbit/s PHY for + LE Long Range + High Duty Cycle Non-Connectable Advertising + LE Advertising Extensions + LE Channel Selection Algorithm #2 + +Features Added in CSA5 – Integrated in v5.0: + Higher Output Power + +The following features were removed in this version of the specification: + Park State + +Bluetooth 5.1 +The Bluetooth SIG presented Bluetooth 5.1 on 21 January 2019. + +The major areas of improvement are: + Angle of Arrival (AoA) and Angle of Departure (AoD) which are used for locating and tracking of devices + Advertising Channel Index + GATT caching + Minor Enhancements batch 1: + HCI support for debug keys in LE Secure Connections + Sleep clock accuracy update mechanism + ADI field in scan response data + Interaction between and Flow Specification + Block Host channel classification for secondary advertising + Allow the SID to appear in scan response reports + Specify the behavior when rules are violated + Periodic Advertising Sync Transfer + +Features Added in Core Specification Addendum (CSA) 6 – Integrated in v5.1: + Models + Mesh-based model hierarchy + +The following features were removed in this version of the specification: + Unit keys + +Bluetooth 5.2 +On 31 December 2019, the Bluetooth SIG published the Bluetooth Core Specification Version 5.2. The new specification adds new features: + + Enhanced Attribute Protocol (EATT), an improved version of the Attribute Protocol (ATT) + LE Power Control + LE Isochronous Channels + LE Audio that is built on top of the new 5.2 features. BT LE Audio was announced in January 2020 at CES by the Bluetooth SIG. Compared to regular Bluetooth Audio, Bluetooth Low Energy Audio makes lower battery consumption possible and creates a standardized way of transmitting audio over BT LE. Bluetooth LE Audio also allows one-to-many and many-to-one transmission, allowing multiple receivers from one source or one receiver for multiple sources, known as Auracast. It uses a new LC3 codec. BLE Audio will also add support for hearing aids. On 12 July 2022, the Bluetooth SIG announced the completion of Bluetooth LE Audio. The standard has a lower minimum latency claim of 20–30 ms vs Bluetooth Classic audio of 100–200 ms. At IFA in August 2023 Samsung announced support for Auracast through a software update for their Galaxy Buds2 Pro and two of their TV's. In October users started getting updates for the earbuds. + +Bluetooth 5.3 +The Bluetooth SIG published the Bluetooth Core Specification Version 5.3 on 13 July 2021. The feature enhancements of Bluetooth 5.3 are: + + Connection Subrating + Periodic Advertisement Interval + Channel Classification Enhancement + Encryption key size control enhancements + +The following features were removed in this version of the specification: + Alternate MAC and PHY (AMP) Extension + +Bluetooth 5.4 +The Bluetooth SIG released the Bluetooth Core Specification Version 5.4 on 7 February 2023. This new version adds the following features: + + Periodic Advertising with Responses (PAwR) + Encrypted Advertising Data + LE Security Levels Characteristic + Advertising Coding Selection + +Technical information + +Architecture + +Software +Seeking to extend the compatibility of Bluetooth devices, the devices that adhere to the standard use an interface called HCI (Host Controller Interface) between the host and the controller. + +High-level protocols such as the SDP (Protocol used to find other Bluetooth devices within the communication range, also responsible for detecting the function of devices in range), RFCOMM (Protocol used to emulate serial port connections) and TCS (Telephony control protocol) interact with the baseband controller through the L2CAP (Logical Link Control and Adaptation Protocol). The L2CAP protocol is responsible for the segmentation and reassembly of the packets. + +Hardware +The hardware that makes up the Bluetooth device is made up of, logically, two parts; which may or may not be physically separate. A radio device, responsible for modulating and transmitting the signal; and a digital controller. The digital controller is likely a CPU, one of whose functions is to run a Link Controller; and interfaces with the host device; but some functions may be delegated to hardware. The Link Controller is responsible for the processing of the baseband and the management of ARQ and physical layer FEC protocols. In addition, it handles the transfer functions (both asynchronous and synchronous), audio coding (e.g. SBC (codec)) and data encryption. The CPU of the device is responsible for attending the instructions related to Bluetooth of the host device, in order to simplify its operation. To do this, the CPU runs software called Link Manager that has the function of communicating with other devices through the LMP protocol. + +A Bluetooth device is a short-range wireless device. Bluetooth devices are fabricated on RF CMOS integrated circuit (RF circuit) chips. + +Bluetooth protocol stack + +Bluetooth is defined as a layer protocol architecture consisting of core protocols, cable replacement protocols, telephony control protocols, and adopted protocols. Mandatory protocols for all Bluetooth stacks are LMP, L2CAP and SDP. In addition, devices that communicate with Bluetooth almost universally can use these protocols: HCI and RFCOMM. + +Link Manager +The Link Manager (LM) is the system that manages establishing the connection between devices. It is responsible for the establishment, authentication and configuration of the link. The Link Manager locates other managers and communicates with them via the management protocol of the LMP link. To perform its function as a service provider, the LM uses the services included in the Link Controller (LC). +The Link Manager Protocol basically consists of several PDUs (Protocol Data Units) that are sent from one device to another. The following is a list of supported services: + Transmission and reception of data. + Name request + Request of the link addresses. + Establishment of the connection. + Authentication. + Negotiation of link mode and connection establishment. + +Host Controller Interface +The Host Controller Interface provides a command interface between the controller and the host. + +Logical Link Control and Adaptation Protocol +The Logical Link Control and Adaptation Protocol (L2CAP) is used to multiplex multiple logical connections between two devices using different higher level protocols. +Provides segmentation and reassembly of on-air packets. + +In Basic mode, L2CAP provides packets with a payload configurable up to 64 kB, with 672 bytes as the default MTU, and 48 bytes as the minimum mandatory supported MTU. + +In Retransmission and Flow Control modes, L2CAP can be configured either for isochronous data or reliable data per channel by performing retransmissions and CRC checks. + +Bluetooth Core Specification Addendum 1 adds two additional L2CAP modes to the core specification. These modes effectively deprecate original Retransmission and Flow Control modes: + Enhanced Retransmission Mode (ERTM) This mode is an improved version of the original retransmission mode. This mode provides a reliable L2CAP channel. + Streaming Mode (SM) This is a very simple mode, with no retransmission or flow control. This mode provides an unreliable L2CAP channel. + +Reliability in any of these modes is optionally and/or additionally guaranteed by the lower layer Bluetooth BDR/EDR air interface by configuring the number of retransmissions and flush timeout (time after which the radio flushes packets). In-order sequencing is guaranteed by the lower layer. + +Only L2CAP channels configured in ERTM or SM may be operated over AMP logical links. + +Service Discovery Protocol +The Service Discovery Protocol (SDP) allows a device to discover services offered by other devices, and their associated parameters. For example, when you use a mobile phone with a Bluetooth headset, the phone uses SDP to determine which Bluetooth profiles the headset can use (Headset Profile, Hands Free Profile (HFP), Advanced Audio Distribution Profile (A2DP) etc.) and the protocol multiplexer settings needed for the phone to connect to the headset using each of them. Each service is identified by a Universally Unique Identifier (UUID), with official services (Bluetooth profiles) assigned a short form UUID (16 bits rather than the full 128). + +Radio Frequency Communications +Radio Frequency Communications (RFCOMM) is a cable replacement protocol used for generating a virtual serial data stream. RFCOMM provides for binary data transport and emulates [[EIA-1325 +]] (formerly RS-232) control signals over the Bluetooth baseband layer, i.e., it is a serial port emulation. + +RFCOMM provides a simple, reliable, data stream to the user, similar to TCP. It is used directly by many telephony related profiles as a carrier for AT commands, as well as being a transport layer for OBEX over Bluetooth. + +Many Bluetooth applications use RFCOMM because of its widespread support and publicly available API on most operating systems. Additionally, applications that used a serial port to communicate can be quickly ported to use RFCOMM. + +Bluetooth Network Encapsulation Protocol +The Bluetooth Network Encapsulation Protocol (BNEP) is used for transferring another protocol stack's data via an L2CAP channel. +Its main purpose is the transmission of IP packets in the Personal Area Networking Profile. +BNEP performs a similar function to SNAP in Wireless LAN. + +Audio/Video Control Transport Protocol +The Audio/Video Control Transport Protocol (AVCTP) is used by the remote control profile to transfer AV/C commands over an L2CAP channel. The music control buttons on a stereo headset use this protocol to control the music player. + +Audio/Video Distribution Transport Protocol +The Audio/Video Distribution Transport Protocol (AVDTP) is used by the advanced audio distribution (A2DP) profile to stream music to stereo headsets over an L2CAP channel intended for video distribution profile in the Bluetooth transmission. + +Telephony Control Protocol +The Telephony Control Protocol– Binary (TCS BIN) is the bit-oriented protocol that defines the call control signaling for the establishment of voice and data calls between Bluetooth devices. Additionally, "TCS BIN defines mobility management procedures for handling groups of Bluetooth TCS devices." + +TCS-BIN is only used by the cordless telephony profile, which failed to attract implementers. As such it is only of historical interest. + +Adopted protocols +Adopted protocols are defined by other standards-making organizations and incorporated into Bluetooth's protocol stack, allowing Bluetooth to code protocols only when necessary. The adopted protocols include: +Point-to-Point Protocol (PPP) Internet standard protocol for transporting IP datagrams over a point-to-point link. +TCP/IP/UDP Foundation Protocols for TCP/IP protocol suite +Object Exchange Protocol (OBEX) Session-layer protocol for the exchange of objects, providing a model for object and operation representation +Wireless Application Environment/Wireless Application Protocol (WAE/WAP) WAE specifies an application framework for wireless devices and WAP is an open standard to provide mobile users access to telephony and information services. + +Baseband error correction +Depending on packet type, individual packets may be protected by error correction, either 1/3 rate forward error correction (FEC) or 2/3 rate. In addition, packets with CRC will be retransmitted until acknowledged by automatic repeat request (ARQ). + +Setting up connections +Any Bluetooth device in discoverable mode transmits the following information on demand: + Device name + Device class + List of services + Technical information (for example: device features, manufacturer, Bluetooth specification used, clock offset) + +Any device may perform an inquiry to find other devices to connect to, and any device can be configured to respond to such inquiries. However, if the device trying to connect knows the address of the device, it always responds to direct connection requests and transmits the information shown in the list above if requested. Use of a device's services may require pairing or acceptance by its owner, but the connection itself can be initiated by any device and held until it goes out of range. Some devices can be connected to only one device at a time, and connecting to them prevents them from connecting to other devices and appearing in inquiries until they disconnect from the other device. + +Every device has a unique 48-bit address. However, these addresses are generally not shown in inquiries. Instead, friendly Bluetooth names are used, which can be set by the user. This name appears when another user scans for devices and in lists of paired devices. + +Most cellular phones have the Bluetooth name set to the manufacturer and model of the phone by default. Most cellular phones and laptops show only the Bluetooth names and special programs are required to get additional information about remote devices. This can be confusing as, for example, there could be several cellular phones in range named T610 (see Bluejacking). + +Pairing and bonding + +Motivation +Many services offered over Bluetooth can expose private data or let a connecting party control the Bluetooth device. Security reasons make it necessary to recognize specific devices, and thus enable control over which devices can connect to a given Bluetooth device. At the same time, it is useful for Bluetooth devices to be able to establish a connection without user intervention (for example, as soon as in range). + +To resolve this conflict, Bluetooth uses a process called bonding, and a bond is generated through a process called pairing. The pairing process is triggered either by a specific request from a user to generate a bond (for example, the user explicitly requests to "Add a Bluetooth device"), or it is triggered automatically when connecting to a service where (for the first time) the identity of a device is required for security purposes. These two cases are referred to as dedicated bonding and general bonding respectively. + +Pairing often involves some level of user interaction. This user interaction confirms the identity of the devices. When pairing completes, a bond forms between the two devices, enabling those two devices to connect in the future without repeating the pairing process to confirm device identities. When desired, the user can remove the bonding relationship. + +Implementation +During pairing, the two devices establish a relationship by creating a shared secret known as a link key. If both devices store the same link key, they are said to be paired or bonded. A device that wants to communicate only with a bonded device can cryptographically authenticate the identity of the other device, ensuring it is the same device it previously paired with. Once a link key is generated, an authenticated ACL link between the devices may be encrypted to protect exchanged data against eavesdropping. Users can delete link keys from either device, which removes the bond between the devices—so it is possible for one device to have a stored link key for a device it is no longer paired with. + +Bluetooth services generally require either encryption or authentication and as such require pairing before they let a remote device connect. Some services, such as the Object Push Profile, elect not to explicitly require authentication or encryption so that pairing does not interfere with the user experience associated with the service use-cases. + +Pairing mechanisms +Pairing mechanisms changed significantly with the introduction of Secure Simple Pairing in Bluetooth v2.1. The following summarizes the pairing mechanisms: + Legacy pairing: This is the only method available in Bluetooth v2.0 and before. Each device must enter a PIN code; pairing is only successful if both devices enter the same PIN code. Any 16-byte UTF-8 string may be used as a PIN code; however, not all devices may be capable of entering all possible PIN codes. + Limited input devices: The obvious example of this class of device is a Bluetooth Hands-free headset, which generally have few inputs. These devices usually have a fixed PIN, for example "0000" or "1234", that are hard-coded into the device. + Numeric input devices: Mobile phones are classic examples of these devices. They allow a user to enter a numeric value up to 16 digits in length. + Alpha-numeric input devices: PCs and smartphones are examples of these devices. They allow a user to enter full UTF-8 text as a PIN code. If pairing with a less capable device the user must be aware of the input limitations on the other device; there is no mechanism available for a capable device to determine how it should limit the available input a user may use. + Secure Simple Pairing (SSP): This is required by Bluetooth v2.1, although a Bluetooth v2.1 device may only use legacy pairing to interoperate with a v2.0 or earlier device. Secure Simple Pairing uses a form of public-key cryptography, and some types can help protect against man in the middle, or MITM attacks. SSP has the following authentication mechanisms: + Just works: As the name implies, this method just works, with no user interaction. However, a device may prompt the user to confirm the pairing process. This method is typically used by headsets with minimal IO capabilities, and is more secure than the fixed PIN mechanism this limited set of devices uses for legacy pairing. This method provides no man-in-the-middle (MITM) protection. + Numeric comparison: If both devices have a display, and at least one can accept a binary yes/no user input, they may use Numeric Comparison. This method displays a 6-digit numeric code on each device. The user should compare the numbers to ensure they are identical. If the comparison succeeds, the user(s) should confirm pairing on the device(s) that can accept an input. This method provides MITM protection, assuming the user confirms on both devices and actually performs the comparison properly. + Passkey Entry: This method may be used between a device with a display and a device with numeric keypad entry (such as a keyboard), or two devices with numeric keypad entry. In the first case, the display presents a 6-digit numeric code to the user, who then enters the code on the keypad. In the second case, the user of each device enters the same 6-digit number. Both of these cases provide MITM protection. + Out of band (OOB): This method uses an external means of communication, such as near-field communication (NFC) to exchange some information used in the pairing process. Pairing is completed using the Bluetooth radio, but requires information from the OOB mechanism. This provides only the level of MITM protection that is present in the OOB mechanism. + +SSP is considered simple for the following reasons: + In most cases, it does not require a user to generate a passkey. + For use cases not requiring MITM protection, user interaction can be eliminated. + For numeric comparison, MITM protection can be achieved with a simple equality comparison by the user. + Using OOB with NFC enables pairing when devices simply get close, rather than requiring a lengthy discovery process. + +Security concerns +Prior to Bluetooth v2.1, encryption is not required and can be turned off at any time. Moreover, the encryption key is only good for approximately 23.5 hours; using a single encryption key longer than this time allows simple XOR attacks to retrieve the encryption key. + Turning off encryption is required for several normal operations, so it is problematic to detect if encryption is disabled for a valid reason or a security attack. +Bluetooth v2.1 addresses this in the following ways: + Encryption is required for all non-SDP (Service Discovery Protocol) connections + A new Encryption Pause and Resume feature is used for all normal operations that require that encryption be disabled. This enables easy identification of normal operation from security attacks. + The encryption key must be refreshed before it expires. +Link keys may be stored on the device file system, not on the Bluetooth chip itself. Many Bluetooth chip manufacturers let link keys be stored on the device—however, if the device is removable, this means that the link key moves with the device. + +Security + +Overview + +Bluetooth implements confidentiality, authentication and key derivation with custom algorithms based on the SAFER+ block cipher. Bluetooth key generation is generally based on a Bluetooth PIN, which must be entered into both devices. This procedure might be modified if one of the devices has a fixed PIN (e.g., for headsets or similar devices with a restricted user interface). During pairing, an initialization key or master key is generated, using the E22 algorithm. +The E0 stream cipher is used for encrypting packets, granting confidentiality, and is based on a shared cryptographic secret, namely a previously generated link key or master key. Those keys, used for subsequent encryption of data sent via the air interface, rely on the Bluetooth PIN, which has been entered into one or both devices. + +An overview of Bluetooth vulnerabilities exploits was published in 2007 by Andreas Becker. + +In September 2008, the National Institute of Standards and Technology (NIST) published a Guide to Bluetooth Security as a reference for organizations. It describes Bluetooth security capabilities and how to secure Bluetooth technologies effectively. While Bluetooth has its benefits, it is susceptible to denial-of-service attacks, eavesdropping, man-in-the-middle attacks, message modification, and resource misappropriation. Users and organizations must evaluate their acceptable level of risk and incorporate security into the lifecycle of Bluetooth devices. To help mitigate risks, included in the NIST document are security checklists with guidelines and recommendations for creating and maintaining secure Bluetooth piconets, headsets, and smart card readers. + +Bluetooth v2.1 – finalized in 2007 with consumer devices first appearing in 2009 – makes significant changes to Bluetooth's security, including pairing. See the pairing mechanisms section for more about these changes. + +The most common cyber attacks of Bluetooth devices +When a Bluetooth device transmits unwanted spam and phishing messages to another Bluetooth device, it is known as bluejacking. Bluesnarfing is a malicious hack that uses a Bluetooth connection to steal information from one's device. Bluesmacking is a denial of service (DoS) attack that attempts to overload one's device and shut it down. Bluebugging is a sort of attack in which a cybercriminal uses a hidden Bluetooth connection to acquire backdoor access to one's device. Car whispering is a Bluetooth security flaw that affects Bluetooth-enabled car radios. + +Cybersecurity compliance of bluetooth devices +RED + +The Radio Equipment Directive 2014/53/EU (RED) regulates radio equipment's electromagnetic compatibility, safety, health, and radio spectrum efficiency. The Directive's Article 3(3) replaces radio-specific equipment cybersecurity with common interface standards. Radio equipment marketed in the EU must meet cybersecurity criteria in Article 3 (3) of the Radio Equipment Directive (RED). + +Consumer IoT devices + +ETSI EN 303 645  prepares the devices to guard against the most prevalent cybersecurity risks and prevent large-scale assaults on connected devices. It lays the groundwork for IoT certification. It has 13 cybersecurity categories and data protection regulations. In addition to device security requirements, it offers advice for managing security risks, including identification, assessment, deployment of controls, and continuing monitoring. + +Bluejacking + +Bluejacking is the sending of either a picture or a message from one user to an unsuspecting user through Bluetooth wireless technology. Common applications include short messages, e.g., "You've just been bluejacked!" Bluejacking does not involve the removal or alteration of any data from the device. + +Some form of DoS is also possible, even in modern devices, by sending unsolicited pairing requests in rapid succession; this becomes disruptive because most systems display a full screen notification for every connection request, interrupting every other activity, especially on less powerful devices. + +History of security concerns + +2001–2004 +In 2001, Jakobsson and Wetzel from Bell Laboratories discovered flaws in the Bluetooth pairing protocol and also pointed to vulnerabilities in the encryption scheme. In 2003, Ben and Adam Laurie from A.L. Digital Ltd. discovered that serious flaws in some poor implementations of Bluetooth security may lead to disclosure of personal data. In a subsequent experiment, Martin Herfurt from the trifinite.group was able to do a field-trial at the CeBIT fairgrounds, showing the importance of the problem to the world. A new attack called BlueBug was used for this experiment. In 2004 the first purported virus using Bluetooth to spread itself among mobile phones appeared on the Symbian OS. +The virus was first described by Kaspersky Lab and requires users to confirm the installation of unknown software before it can propagate. The virus was written as a proof-of-concept by a group of virus writers known as "29A" and sent to anti-virus groups. Thus, it should be regarded as a potential (but not real) security threat to Bluetooth technology or Symbian OS since the virus has never spread outside of this system. In August 2004, a world-record-setting experiment (see also Bluetooth sniping) showed that the range of Class 2 Bluetooth radios could be extended to with directional antennas and signal amplifiers. +This poses a potential security threat because it enables attackers to access vulnerable Bluetooth devices from a distance beyond expectation. The attacker must also be able to receive information from the victim to set up a connection. No attack can be made against a Bluetooth device unless the attacker knows its Bluetooth address and which channels to transmit on, although these can be deduced within a few minutes if the device is in use. + +2005 +In January 2005, a mobile malware worm known as Lasco surfaced. The worm began targeting mobile phones using Symbian OS (Series 60 platform) using Bluetooth enabled devices to replicate itself and spread to other devices. The worm is self-installing and begins once the mobile user approves the transfer of the file (Velasco.sis) from another device. Once installed, the worm begins looking for other Bluetooth enabled devices to infect. Additionally, the worm infects other .SIS files on the device, allowing replication to another device through the use of removable media (Secure Digital, CompactFlash, etc.). The worm can render the mobile device unstable. + +In April 2005, Cambridge University security researchers published results of their actual implementation of passive attacks against the PIN-based pairing between commercial Bluetooth devices. They confirmed that attacks are practicably fast, and the Bluetooth symmetric key establishment method is vulnerable. To rectify this vulnerability, they designed an implementation that showed that stronger, asymmetric key establishment is feasible for certain classes of devices, such as mobile phones. + +In June 2005, Yaniv Shaked and Avishai Wool published a paper describing both passive and active methods for obtaining the PIN for a Bluetooth link. The passive attack allows a suitably equipped attacker to eavesdrop on communications and spoof if the attacker was present at the time of initial pairing. The active method makes use of a specially constructed message that must be inserted at a specific point in the protocol, to make the master and slave repeat the pairing process. After that, the first method can be used to crack the PIN. This attack's major weakness is that it requires the user of the devices under attack to re-enter the PIN during the attack when the device prompts them to. Also, this active attack probably requires custom hardware, since most commercially available Bluetooth devices are not capable of the timing necessary. + +In August 2005, police in Cambridgeshire, England, issued warnings about thieves using Bluetooth enabled phones to track other devices left in cars. Police are advising users to ensure that any mobile networking connections are de-activated if laptops and other devices are left in this way. + +2006 +In April 2006, researchers from Secure Network and F-Secure published a report that warns of the large number of devices left in a visible state, and issued statistics on the spread of various Bluetooth services and the ease of spread of an eventual Bluetooth worm. + +In October 2006, at the Luxemburgish Hack.lu Security Conference, Kevin Finistere and Thierry Zoller demonstrated and released a remote root shell via Bluetooth on Mac OS X v10.3.9 and v10.4. They also demonstrated the first Bluetooth PIN and Linkkeys cracker, which is based on the research of Wool and Shaked. + +2017 +In April 2017, security researchers at Armis discovered multiple exploits in the Bluetooth software in various platforms, including Microsoft Windows, Linux, Apple iOS, and Google Android. These vulnerabilities are collectively called "BlueBorne". The exploits allow an attacker to connect to devices or systems without authentication and can give them "virtually full control over the device". Armis contacted Google, Microsoft, Apple, Samsung and Linux developers allowing them to patch their software before the coordinated announcement of the vulnerabilities on 12 September 2017. + +2018 +In July 2018, Lior Neumann and Eli Biham, researchers at the Technion – Israel Institute of Technology identified a security vulnerability in the latest Bluetooth pairing procedures: Secure Simple Pairing and LE Secure Connections. + +Also, in October 2018, Karim Lounis, a network security researcher at Queen's University, identified a security vulnerability, called CDV (Connection Dumping Vulnerability), on various Bluetooth devices that allows an attacker to tear down an existing Bluetooth connection and cause the deauthentication and disconnection of the involved devices. The researcher demonstrated the attack on various devices of different categories and from different manufacturers. + +2019 + +In August 2019, security researchers at the Singapore University of Technology and Design, Helmholtz Center for Information Security, and University of Oxford discovered a vulnerability, called KNOB (Key Negotiation Of Bluetooth) in the key negotiation that would "brute force the negotiated encryption keys, decrypt the eavesdropped ciphertext, and inject valid encrypted messages (in real-time)". + + Google released an Android security patch on 5 August 2019, which removed this vulnerability. + +Health concerns + +Bluetooth uses the radio frequency spectrum in the 2.402GHz to 2.480GHz range, which is non-ionizing radiation, of similar bandwidth to that used by wireless and mobile phones. No specific harm has been demonstrated, even though wireless transmission has been included by IARC in the possible carcinogen list. Maximum power output from a Bluetooth radio is 100mW for class 1, 2.5mW for class 2, and 1mW for class 3 devices. Even the maximum power output of class1 is a lower level than the lowest-powered mobile phones. UMTS and W-CDMA output 250mW, GSM1800/1900 outputs 1000mW, and GSM850/900 outputs 2000mW. + +Award programs +The Bluetooth Innovation World Cup, a marketing initiative of the Bluetooth Special Interest Group (SIG), was an international competition that encouraged the development of innovations for applications leveraging Bluetooth technology in sports, fitness and health care products.

The SIG is a not-for-profit, non-stock corporation founded in September 1998. The SIG is headquartered in Kirkland, Washington. + +The SIG does not make, manufacture or sell Bluetooth-enabled products. + +Introduction +Bluetooth technology provides a way to exchange information between wireless devices such as PDAs, laptops, computers, printers and digital cameras via a secure, low-cost, globally available short-range radio frequency band. Originally developed by Ericsson, Bluetooth technology is now used in many different products by many different manufacturers. These manufacturers must be either Associate or Promoter members of(see below) the Bluetooth SIG before they are granted early access to the Bluetooth specifications, but published Bluetooth specifications are available online via the Bluetooth SIG Website bluetooth.com. + +The SIG owns the Bluetooth word mark, figure mark and combination mark. These trademarks are licensed out for use to companies that are incorporating Bluetooth wireless technology into their products. To become a licensee, a company must become a member of the Bluetooth SIG. The SIG also manages the Bluetooth SIG Qualification program, a certification process required for any product using Bluetooth wireless technology and a pre-condition of the intellectual property license for Bluetooth technology. The main tasks for the SIG are to publish the Bluetooth specifications, protect the Bluetooth trademarks and evangelize Bluetooth wireless technology. In 2016, the SIG introduced a new visual and creative identity to support Bluetooth technology as the catalyst for the Internet of Things (IoT). This change included an updated logo, a new tagline and deprecation of the Bluetooth Smart and Bluetooth Smart Ready logos. + +At its inception in 1998, the Bluetooth SIG was primarily run by a staff effectively seconded from its member companies. In 2001 Tom Siep served as the group's managing director, and from 2002 to 2004 Mike McCamon led the group as its executive director. In 2004 he was replaced by Michael W. Foley (Mike). In mid-2012, Mark Powell took the reins as the SIG's current executive director. Beginning in 2002 a professional staff was hired, composed of operations, engineering and marketing specialists. From 2002 to 2004 the Bluetooth SIG was based in Overland Park, Kansas, US, and is now based in Kirkland, Washington. In addition to its professional staff, the SIG is supported by its more than 35,000 member companies who participate in the various working groups that produce the standardization documents and oversee the qualification process for new products and help to evangelize the technology. + +Structure +The SIG members participate in study groups, expert groups, working groups along with committees. + +Study groups +The study groups carry out research into their various areas which informs the development of the Bluetooth specifications. They may eventually become working groups in their own right. + +Expert groups +The expert groups deal with issues of technical importance to all aspects of Bluetooth development.

Associate membership is renewed annually and the yearly fee depends on the individual company's revenue. Companies with annual revenue in excess of $100M US are considered Large Associates and pay annual membership fees of $42,000 US. Small Associates are categorized as those organizations with revenue less than $100M US and join the SIG with an annual membership fee of $9,000 US. Associate members of the SIG get early access to draft specifications at versions 0.5 and 0.7 and are eligible to participate and gain a voting seat in working groups and committees—a key opportunity to work with other Associate and Promoter members on enhancing existing specifications. They are also eligible for enhanced marketing support, receive discounts on product qualification listings and SIG events including Bluetooth World and UnPlugFest (UPF) testing events. + +Adopter members +Adopter membership in the SIG is free and entitles members to use published Bluetooth wireless specifications and Bluetooth trademarks.

Originally based in West Germany, the four original members of the group's official line-up were Liz Mitchell and Marcia Barrett from Jamaica, Maizie Williams from Montserrat, and Bobby Farrell from Aruba. The group was formed in 1976 and achieved popularity during the disco era of the late 1970s. Since the 1980s, various line-ups of the band have performed with differing personnel. + +The band has sold more than 100 million records worldwide and is known for international hits including "Daddy Cool", "Ma Baker", "Belfast", "Sunny", "Rasputin", "Mary's Boy Child/Oh My Lord" and "Rivers of Babylon". + +History + +1974–1976: Formation and early career +German singer-songwriter Frank Farian recorded the dance track "Baby Do You Wanna Bump" in December 1974. Farian sang the repeated line "Do you do you wanna bump?" in a deep voice as well as performing the high falsetto chorus. When the record was released as a single in early 1975, it was credited to "Boney M." Farian had created this pseudonym for himself after watching the Australian television detective series Boney, whose main character was named Napoleon Bonaparte. Farian said: + +After a slow start, the song became a hit in the Netherlands and Belgium. It was then that Farian decided to hire performers to create a troupe for TV appearances. Farian found model-turned-singer Maizie Williams (originally from Montserrat), Bobby Farrell, a dancer from Aruba, and singer Marcia Barrett from Jamaica who brought in singer Liz Mitchell, also from Jamaica and a former member of the Les Humphries Singers. + +1976–1979: Take the Heat off Me and international success +Boney M.'s first album, Take the Heat off Me, was released in 1976. It contained tracks that Marcia Barrett had already recorded with Farian, including the title track and "Lovin' or Leavin, both of which were previously recorded in German by another Farian act, Gilla. As Maizie Williams' voice was not considered suitable for recording purposes by Farian, and a try-out with Bobby Farrell performing "No Woman No Cry" did not work, Farian decided to use only Liz Mitchell and Marcia Barrett along with his own studio-enhanced voice to create the Boney M. sound. + +The album's commercial performance was initially lukewarm. However, the group rigorously toured discos, clubs, and even country fairs to earn a reputation for themselves. The group's big break came when, at the end of summer 1976, German television producer Michael "Mike" Leckebusch (of Radio Bremen) requested them for his show Musikladen. Boney M. appeared on the live music show on 18 September 1976, after 10:00 p.m. and in their daring stage costumes, where they performed the song "Daddy Cool". The song quickly went to no.1 in Germany, with the album following the success of the single. Another single, "Sunny" (a cover of the 1966 Bobby Hebb song) gave the group their second no.1 hit. The group's popularity had also grown throughout Europe, with "Daddy Cool" reaching no.1 in Switzerland, Sweden, Norway, Spain, France, and Austria. Both singles were also Top 10 hits in the UK, which would become one of their biggest markets. + +In 1977, Boney M. released their second album, Love for Sale, which contained the hits "Ma Baker" and "Belfast". The group embarked on their first major concert tours with a live band of musicians called "The Black Beauty Circus" (given their name after Maizie Williams' first band, "Black Beautiful People"). Love for Sale was certified Gold a year after its release in the UK. Both singles from the album reached no.1 in Germany and the UK Top 10. + +1978 was the group's biggest year. They released a new double A-sided single, "Rivers of Babylon/Brown Girl in the Ring", which was a hit all over Europe, reaching no. 1 in several countries as well as becoming one of the biggest selling singles of all time in the UK. It also became their most successful single in the United States, peaking at no. 30 on the U.S. pop singles chart. Following this came their biggest-selling album, Nightflight to Venus, which spawned further hit singles with "Rasputin" and "Painter Man". Continuing with their success, they released "Mary's Boy Child – Oh My Lord", which was the 1978 Christmas number one single in the United Kingdom and became another of the biggest selling singles of all time there. Also during 1978, Boney M. made a much-publicized promotional visit to the Soviet Union, one of the very few Western acts along with Elton John to do so, although tracks like "Rasputin" were not released in the Soviet Union due to their lyrics. + +While it had never been a secret that Bobby Farrell never sang on the group's records (Farian did the male vocals in the studio), in 1978 it became public knowledge that Maizie Williams did not sing on the studio recordings either, since "her voice wasn't suited for this kind of music" as Farian stated in an interview with German teen magazine Bravo. Since this had become common practice within the disco genre of the late 1970s, few people cared – unlike when Farian repeated the practice to much more severe backlash with Milli Vanilli in the late 1980s. While only two of Boney M.'s official members actually contributed to the band's records, all four members of the group, including Williams and Farrell, performed the vocals live at Boney M. concerts. The band's live sound was also augmented by several backing vocalists, which served to mitigate any vocal deficiencies the group may have had compared with the studio productions. + +1979 saw Boney M. release a brand new single, "Hooray! Hooray! It's a Holi-Holiday", which became another Top 10 hit across Europe. Later in the year they released their fourth album, Oceans of Fantasy, containing two hit singles – "Gotta Go Home"/"El Lute" and "I'm Born Again"/"Bahama Mama". The album also included a "Lead" and "Backing Vocals" credit for the first time. Oceans of Fantasy reached no.1 in the UK and was certified Platinum, though their run of Top 10 singles had now ended with "Gotta Go Home" peaking at no.12 and "I'm Born Again" peaking at no. 5. + +1980–1986: The Magic of Boney M. Departure of Farrell and Split +In 1980, Boney M. released a greatest hits album, The Magic of Boney M. – 20 Golden Hits, which also contained two new songs, "My Friend Jack" and "I See a Boat on the River". It made the no. 1 spot in the UK, reaching Gold status within six weeks of release, though it was their last big-selling album in the UK. + +Boney M.'s fifth album had been scheduled for release in November 1980 but the recording sessions dragged on all through 1981. When Boonoonoonoos was finally released by the end of that year, Bobby Farrell departed from the group due to issues with Frank Farian. While still a healthy seller in continental Europe, Boonoonoonoos failed to crack the UK Top 100 after three consecutive no. 1 albums due to the group being unable to promote it after Farrell left. Following this, the group released a Christmas Album. + +Reggie Tsiboe was hired to replace Farrell as the new male member of Boney M. in 1982 but the singles "The Carnival Is Over" and "Jambo" fared poorly, and the group's seventh album Ten Thousand Lightyears, issued in 1984, marked another commercial low point, peaking at number 23 in the German album charts. The group, however, returned to the German Top 20 in the autumn of 1984 with "Kalimba de Luna" (a Top 10 hit in France) and "Happy Song" (a cover of a song by Italian Italo-disco band Baby's Gang), the latter seeing Bobby Farrell return to the group. Both songs were carbon-copies of the original Italian hits by Tony Esposito and Baby's Gang respectively. + +By 1985, Farian clearly began losing interest in the group, and their final and eighth studio album Eye Dance was widely regarded as uninspired and disappointing. After celebrating Boney M.'s 10th anniversary in early 1986, the group officially disbanded after the release of the commercially unsuccessful single "Young, Free and Single", which peaked at no.48. + +1990 and on: Failed reunions and public interest + +From this point, different versions of the group were formed by members, some with cooperation of Farian, others without (for example by independently obtaining the rights to use the Boney M. name in a different country). One version began touring in the first half of 1987 with Marilyn Scharbaai (Carrilho) taking Liz Mitchell's place. Mitchell returned for a second leg of the tour late 1987, and Marcia Barrett soon left the band. At the same time, Bobby Farrell had set up a deal for a new Boney M. album to be recorded without Farian in Belgium. When Farrell failed to show up for either recording or tour, and Maizie Williams had never sung on record, the album ended up being released as Liz Mitchell's first solo album No One Will Force You. Mitchell and Williams completed a tour during 1987–88, adding singer Celena Duncan and Ron Gale as replacements for Barrett and Farrell. Carol Grey later replaced Celena Duncan and Curt De Daran later replaced Ron Gale. + +In October 1988, the classic Boney M. line-up reunited without producer Frank Farian for the album Greatest Hits of All Times – Remix '88 but tensions ran high between the members, and Liz Mitchell left in the spring of 1989 to be replaced by Madeleine Davis. While Mitchell promoted her solo album, the group recorded the single "Everybody Wants to Dance Like Josephine Baker", without Farian's knowledge or approval. Threatened with legal action by the producer over the use of the Boney M. name, the single was subsequently withdrawn and Farian issued Stories with his own new Boney M. line-up featuring Liz Mitchell, Reggie Tsiboe and two new members, Sharon Stevens and Patty Onoyewenjo, Stories peaked at number 11 in the Swiss charts. A second remix album Greatest Hits of All Times – Remix '89 – Volume II was released but fared poorly. + +1992 saw a renewed interest in Boney M.'s music with the Boney M. Megamix single returning the group to the UK Top 10 for the first time since 1980, and a subsequent Greatest Hits album reaching the UK Top 20 in 1993. While Marcia Barrett, now residing in Florida, was battling cancer and unable to perform, Boney M. toured the world with a line-up of Liz Mitchell, Carol Grey, Patricia Lorna Foster and Curt Dee Daran (replaced by Tony Ashcroft in 1994). They released the single Papa Chico but failed to chart. Maizie Williams assembled her own Boney M. with an ever-changing line-up. Bobby Farrell also toured with varying trios of female performers. +Liz Mitchell was touring the world with her line-up of Boney M., which is the only line-up officially supported by Farian (the court ruling of 1990 stated that all four members are entitled to perform their own Boney M. shows). Bobby Farrell and Liz Mitchell have released solo albums containing their own re-recordings of Boney M.'s classic hits. Maizie Williams released her first solo album in 2006 and her own single version of Boney M.'s Sunny. In 2007 her rendition of "Daddy Cool" with Melo-M hit the number one spot in the Latvian (LMK) Charts. Marcia Barrett has released two solo albums with a third scheduled for release in 2010. + +As recounted in his 1988 book Touching the Void, the British climber Joe Simpson was subsequently to find the catchy tune of Brown Girl in the Ring haunting him in the final hours of his struggle to survive the descent of Siula Grande in the Andes, and the song was later used in the 2003 film of Touching the Void made by Kevin Macdonald. Simpson recalls: "I remember thinking, bloody hell, I'm going to die to Boney M". + +A musical based on the music of Boney M., Daddy Cool, opened in London in August 2006 to mixed reviews and sluggish ticket sales, causing it to close in February 2007. From April to July 2007, the show played in a mobile theatre in Berlin, which was specially designed for it. + +In April 2007, Australian pop singer Peter Wilson released a song co-written by Frank Farian entitled "Doin' Fine". It is described as "paying tribute to the sound of Boney M." and features the famous string arrangement from their first number 1 hit, "Daddy Cool". Boney M. (featuring Marcia Barrett) made a live appearance at the 37th International Film Festival of India (IFFI), which took place on 23 November 2006 in Panaji, the state capital of Goa, India. The group is also popular in the Vietnamese diaspora, and was featured in Thuy Nga music productions. + +In the UK, a new album of their greatest hits, entitled The Magic of Boney M. was released via BMG on 27 November 2006. Special additions to this release were a Mousse T. remix of Sunny and a brand new song from 2006, featuring Liz Mitchell, entitled A Moment of Love. On 10 April 2007, Boney M.'s first four albums were reissued on compact disc with bonus tracks, this time also in the United States (the first time these were available to the U.S. music market since their original releases in the 1970s). + +In September 2007, Boney M.'s last four original albums, Boonoonoonoos, Ten Thousand Lightyears, Kalimba de Luna - 16 Happy Songs and Eye Dance were reissued on compact disc in Europe and the United States, all including bonus tracks. In November 2007, a new Christmas compilation was scheduled for release as well as the DVD Fantastic Boney M. – On Stage and on the Road featuring a live performance recorded in Vienna on 1 November 1977 (the DVD cover erroneously states it to be a live show from Hamburg), and a film from the band's 1981 visit to Jamaica (made to promote the Boonoonoonoos album that year). + +Bobby Farrell's Boney M. performed a concert at the Amphi in Ra'anana, Israel, in May 2007. On 28 June 2007 Boney M. featuring Matthew Felsenfeld and Liz Mitchell performed at the Oktiabrsky concert hall in St. Petersburg, Russia. In September 2007, Maizie Williams' Boney M. line-up performed live at the Royal Albert Hall, UK, to raise awareness of HIV/AIDS in Africa, performing her own renditions of Brown Girl in the Ring and Hooray! Hooray! It's a Holi-Holiday. + +The legal rights to the name "Boney M." have been a matter of controversy, and even court cases, between the former members of the band and producer Frank Farian ever since the late 1980s. Farian, the man who in effect created the group, has continued to work with Liz Mitchell and her line-up all through the 1990s and 2000s. In January 2007, Zanillya Farrell (daughter of Bobby Farrell) and Yasmina Ayad-Saban (ex-wife of Farrell) renewed the trademark to the name Boney M. in Germany for a 10-year period. + +In January 2009, Farian released the single Felicidad America (Obama Obama), a version of the 1980 Boney M. song "Felicidad (Margherita)" with new lyrics about newly elected U.S. president Barack Obama. The song was recorded with two new vocalists, and credited to "Boney M. feat. Sherita O. & Yulee B." + +In July 2010, Maizie Williams headlined a Boney M. performance at Ramallah's Cultural Palace, in the West Bank, as part of the Palestine International Festival. The band played Daddy Cool, Ma Baker and Brown Girl in the Ring, but refrained from playing Rivers of Babylon, rumored to be at the event organizers' request because of its description of the Jewish yearning for Zion. + +Bobby Farrell died at the age of 61 from heart failure on 30 December 2010. His agent said Farrell was complaining of breathing problems after performing with his band the evening before. Farrell lived in Amsterdam until his death. His final performance was in Saint Petersburg, Russia (the city where Rasputin first became famous and was later killed): Farrell died in a hotel room there, 94 years to the day after Rasputin. + +Maizie Williams' line-up of Boney M. toured Australia in June 2014. They sang at Guilfest, Guildford, UK, on 20 July 2014, and Watchet Live music festival UK, on 24 August 2014. + +In March 2015, Farian released Diamonds, a 3CD box celebrating the 40th anniversary of Boney M. It contained re-mastered versions of the original hit singles or of previously unreleased versions, a remix disc and the new digital single Song of Joy featuring Liz Mitchell. A major DVD set was also released. + +In February 2017, they performed at the closing ceremony of Patras Carnival in Patras, Greece. At the end of 2017 the album World Music for Christmas was released under Boney M. and Friends with Liz Mitchell doing vocals on 3 songs, along with the single and video Like Diamonds in the Sky featuring Liz Mitchell, based on El Cóndor Pasa. + +In 2021, a remix of Rasputin by house music producer and Kiss FM DJ Kevin Christie was released by Sony Music's Ministry of Sound label. Credited to Majestic & Boney M (with the former being the DJ alias of Christie), the record reached number 11 on the UK singles chart and was released with a video featuring Bimini Bon-Boulash from RuPaul's Drag Race UK. In December 2021, Mitchell was one of the contributors to the Channel 5 music show Britain's Biggest 70s Hits alongside other musicians from the era like Dean Friedman and Barry Blue, and radio presenters like David Hamilton. + +In August 2023, Boney M. (headed by Liz Mitchell) embarked on a multi city US tour along with Samantha Fox and Bad Boys Blue, which included stops in Boston, Los Angeles, Chicago, New York City and San Jose. The shows were put together by Los Angeles based promoters LA Concert Group. + +UK sales mark +In 1978, "Rivers of Babylon", a cover of a track by The Melodians with lyrics partly based on Psalm 137 and partly on Psalm 19, became (at the time) the second highest-selling single of all time in the UK. After remaining at no.1 for five weeks, "Rivers of Babylon" began dropping down the chart, at which point the B-side "Brown Girl in the Ring" was given extensive radio airplay, and the single ascended to no. 2. The single spent six months in the UK Top 40, including 19 weeks in the Top 10. It eventually sold more than two million copies, the second single to do so, and is still one of only seven to achieve this feat. (see List of million-selling singles in the United Kingdom) + +The group achieved a second UK million-seller with their version of the calypso classic "Mary's Boy Child", released as a medley "Mary's Boy Child – Oh My Lord", which was previously a million-seller for Harry Belafonte. The single sold more than 1.8 million copies, 1.6 million of which were in the four weeks the song was at n.1 in December 1978. + +Boney M. is the only artist to appear twice in the top 12 best selling singles of all time in the UK, with "Rivers of Babylon" in seventh place and "Mary's Boy Child/Oh My Lord" at number 11. They are also one of six artists to sell a million copies with two singles in the same year. + +Back catalogue +Compared to other best-selling artists of the 1970s like ABBA, Donna Summer, and the Bee Gees, the Boney M. discography is quite unusual – while the greater part of the band's back catalogue has been remixed, remade, remodeled and reissued all through the 1980s, 1990s and 2000s by producer Frank Farian and record company BMG-Ariola (now Sony Music), most of the original 7" and 12" versions issued on vinyl in the 1970s and early 1980s remained unavailable on CD until 2007, where they were released on various compilations, most notably The Collection (2008), the Ultimate Boney M. series (2008), Let It All Be Music: The Party Album (2009), Hit Story (2010) and Diamonds (2015). Some of these CDs were compiled by Frank Eberlein, who had also been interviewed on a fansite called "Fantastic Boney M." about the compiling process. + +"Greatest hits" collections containing edited and/or overdubbed versions of the original recordings are still being released, such as Boney M. & Friends (Their Ultimate Top 40 Collection) (2017), Rasputin - Big And Strong: The Greatest Hits of Boney M. (2021) and the 2022 re-issue of the 2006 compilation "The Magic of Boney M." + +Popularity outside the West +Boney M. was hugely popular in the Soviet Union in the 1970s, although the song "Rasputin" was banned by the Soviet authorities during the group's concert in Moscow in December 1978. The song has been used in several movies and television shows, including Johnny English Strikes Again, The King's Man, Black Mirror and in the Doctor Who special The Power of the Doctor, in which The Master dances to the song while disguised as Rasputin himself. + +In the Soviet film Repentance (1984, released 1987), "Sunny" is played at a party of high-ranked communist officials. "Sunny" is played during a few parts of the successful Korean film of the same name, Sunny. + +During the 2002 presidential election campaign of South Korea, then-candidate Roh Moo-hyun, who eventually won the presidency at that event, took Bahama Mama to promote his aim of positive political reform. + +The 2005 Chinese film Shanghai Dreams features a scene depicting a rural Chinese disco in 1983, with teenagers dancing to "Rivers of Babylon" and "Gotta Go Home". + +In the 2008 Kazakh film Tulpan, the tractor driver Boni continually plays a cassette of "Rivers of Babylon", an example of his fascination for all things Western. + +In the 2008 Chinese film Cheung Gong 7 hou (English title: CJ7), "Sunny" is a vital part of the soundtrack. "Sunny" is the theme song of the 2011 Taiwanese drama, Sunny Girl. The song has also appeared in The Umbrella Academy and Boogie Nights. + +Boney M. was immensely popular in India through the 1970s and 1980s. Liz Mitchell recalled her visits to India in the 1980s in a 2015 interview with Hindustan Times: "It was amazing. We’ve had the most-wonderful tours here. We even went out shopping to so many places. We met several Bollywood stars and had dinners with them." + +Personnel + Liz Mitchell – lead and backing vocals (1976–1986, 1988–1989, 1990) + Marcia Barrett – lead and backing vocals (1975–1986, 1988–1989) + Maizie Williams – dancer, live vocals (1975–1986, 1988–1989) + Bobby Farrell – dancer, live vocals (1975–1981, 1984–1986, 1988–1989; died 2010) + Reggie Tsiboe – lead and backing vocals (1982–1986, 1990) + +Discography + +Take the Heat off Me (1976) +Love for Sale (1977) +Nightflight to Venus (1978) +Oceans of Fantasy (1979) +Boonoonoonoos (1981) +Christmas Album (1981) +Ten Thousand Lightyears (1984) +Eye Dance (1985) + +Successful compilation albums + +The Magic of Boney M. – 20 Golden Hits (1980) +Gold – 20 Super Hits (1992) + +References + +External links + + Fantastic Boney M. – The Story of Boney M. + + +Musical groups established in 1975 +German disco groups +Eurodisco groups + +German pop music groups +1975 establishments in West Germany +Atlantic Records artists +German musical quartets +1986 disestablishments in West Germany +Musical groups disestablished in 1986 +Hansa Records artists +Britain most often refers to: + + The United Kingdom, a sovereign state in Europe comprising the island of Great Britain, the north-eastern part of the island of Ireland and many smaller islands + Great Britain, the largest island in: the United Kingdom; the British Isles archipelago; and Europe. + +Britain may also refer to: + +Places + British Isles, an archipelago comprising Great Britain, Ireland and many other smaller islands + British Islands, the UK, Channel Islands and Isle of Man collectively + Roman Britain, a Roman province corresponding roughly to modern-day England and Wales + Historical predecessors to the present-day United Kingdom: + Kingdom of Great Britain (1707 to 1801) + United Kingdom of Great Britain and Ireland (1801 to 1922) + Britain (place name) + Britain, Virginia, an unincorporated community in the United States + +People + Calvin Britain (1800–1862), an American politician + Clarissa Britain (1816–1895), an American inventor + Kristen Britain (born 1965), an American novelist + +Other uses + Captain Britain, a Marvel Comics superhero + +See also + + + Terminology of the British Isles + England + Britains + Britannia + Brittain (disambiguation) + Brittany (disambiguation) + Brit (disambiguation) + Britten (disambiguation) + Briton (disambiguation) + Brittonic languages + British (disambiguation) + Great Britain (disambiguation) + Little Britain (disambiguation) + New Britain (disambiguation) + National sports teams of the United Kingdom +Blade Runner is a 1982 science fiction film directed by Ridley Scott, and written by Hampton Fancher and David Peoples. Starring Harrison Ford, Rutger Hauer, Sean Young, and Edward James Olmos, it is an adaptation of Philip K. Dick's 1968 novel Do Androids Dream of Electric Sheep? The film is set in a dystopian future Los Angeles of 2019, in which synthetic humans known as replicants are bio-engineered by the powerful Tyrell Corporation to work on space colonies. When a fugitive group of advanced replicants led by Roy Batty (Hauer) escapes back to Earth, burnt-out cop Rick Deckard (Ford) reluctantly agrees to hunt them down. + +Blade Runner initially underperformed in North American theaters and polarized critics; some praised its thematic complexity and visuals, while others critiqued its slow pacing and lack of action. The film's soundtrack, composed by Vangelis, was nominated in 1982 for a BAFTA and a Golden Globe as best original score. Blade Runner later became a cult film, and has since come to be regarded as one of the greatest science fiction films. Hailed for its production design depicting a high-tech but decaying future, the film is often regarded as both a leading example of neo-noir cinema as well as a foundational work of the cyberpunk genre. It has influenced many science fiction films, video games, anime, and television series. It also brought the work of Dick to Hollywood's attention and led to several film adaptations of his works. In 1993, it was selected for preservation in the National Film Registry by the Library of Congress. + +Seven different versions of Blade Runner exist as a result of controversial changes requested by studio executives. A director's cut was released in 1992 after a strong response to test screenings of a workprint. This, in conjunction with the film's popularity as a video rental, made it one of the earliest movies to be released on DVD. In 2007, Warner Bros. released The Final Cut, a 25th-anniversary digitally remastered version; this is the only version over which Scott retained artistic control. The film is the first of the franchise of the same name. A sequel, titled Blade Runner 2049, was released in 2017 alongside a trilogy of short films covering the thirty-year span between the two films' settings. The anime series Blade Runner: Black Lotus was released in 2021. + +Plot + +In 2019 Los Angeles, former police officer Rick Deckard is detained by Officer Gaff, who likes to make origami figures, and is brought to his former supervisor, Bryant. Deckard, whose job as a "blade runner" was to track down bioengineered humanoids known as replicants and terminally "retire" them, is informed that four replicants are on Earth illegally. Deckard begins to leave, but Bryant ambiguously threatens him and Deckard stays. The two watch a video of a blade runner named Holden administering the Voight-Kampff test, which is designed to distinguish replicants from humans based on their emotional responses to questions. The test subject, Leon, shoots Holden on the second question. Bryant wants Deckard to retire Leon and three other Nexus-6 replicants: Roy Batty, Zhora, and Pris. + +Bryant has Deckard meet with the CEO of the company that creates the replicants, Eldon Tyrell, so he can administer the test on a Nexus-6 to see if it works. Tyrell expresses his interest in seeing the test fail first and asks him to administer it on his assistant Rachael. After a much longer than standard test, Deckard concludes privately to Tyrell that Rachael is a replicant who believes she is human. Tyrell explains that she is an experiment who has been given false memories to provide an "emotional cushion", and that she has no knowledge of her true nature. + +In searching Leon's hotel room, Deckard finds photos and a scale from the skin of an animal, which is later identified as a synthetic snake scale. Deckard returns to his apartment where Rachael is waiting. She tries to prove her humanity by showing him a family photo, but Deckard reveals that her memories are implants from Tyrell's niece, and she leaves in tears. + +Replicants Roy and Leon meanwhile investigate a replicant eye-manufacturing laboratory and learn of J. F. Sebastian, a gifted genetic designer who works closely with Tyrell. Pris locates Sebastian and manipulates him to gain his trust. + +A photograph from Leon's apartment and the snake scale lead Deckard to a strip club, where Zhora works. After a confrontation and chase, Deckard kills Zhora. Bryant also orders him to retire Rachael, who has disappeared from the Tyrell Corporation. Deckard spots Rachael in a crowd, but he is ambushed by Leon, who knocks the gun out of Deckard's hand and beats him. As Leon is about to kill Deckard, Rachael saves him by using Deckard's gun to kill Leon. They return to Deckard's apartment and, during a discussion, he promises not to track her down. As Rachael abruptly tries to leave, Deckard restrains her and forces her to kiss him, and she ultimately relents. Deckard leaves Rachael at his apartment and departs to search for the remaining replicants. + +Roy arrives at Sebastian's apartment and tells Pris that the other replicants are dead. Sebastian reveals that because of a genetic premature aging disorder, his life will be cut short, like the replicants that were built with a four-year lifespan. Roy uses Sebastian to gain entrance to Tyrell's penthouse. He demands more life from his maker, which Tyrell says is impossible. Roy confesses that he has done "questionable things" but Tyrell dismisses this, praising Roy's advanced design and accomplishments in his short life. Roy kisses Tyrell and then kills him by crushing his skull. Sebastian tries to flee and is later reported dead. + +At Sebastian's apartment, Deckard is ambushed by Pris, but he kills her as Roy returns. Roy's body begins to fail as the end of his lifespan nears. He chases Deckard through the building and onto the roof. Deckard tries to jump onto another roof but is left hanging on the edge. Roy makes the jump with ease and, as Deckard's grip loosens, Roy hoists him onto the roof to save him. Before Roy dies, he laments that his memories "will be lost in time, like tears in rain". Gaff arrives to congratulate Deckard, also reminding him that Rachael will not live, but "then again, who does?" Deckard returns to his apartment to retrieve Rachael. While escorting her to the elevator, he notices a small origami unicorn on the floor. He recalls Gaff's words and departs with Rachael. + +Cast + +Production + +Development + +Interest in adapting Philip K. Dick's novel Do Androids Dream of Electric Sheep? developed shortly after its 1968 publication. Director Martin Scorsese was interested in filming the novel, but never optioned it. Producer Herb Jaffe optioned it in the early 1970s, but Dick was unimpressed with the screenplay written by Herb's son Robert, saying, "Jaffe's screenplay was so terribly done ... Robert flew down to Santa Ana to speak with me about the project. And the first thing I said to him when he got off the plane was, 'Shall I beat you up here at the airport, or shall I beat you up back at my apartment? + +The screenplay by Hampton Fancher was optioned in 1977. Producer Michael Deeley became interested in Fancher's draft and convinced director Ridley Scott to film it. Scott had previously declined the project, but after leaving the slow production of Dune, wanted a faster-paced project to take his mind off his older brother's recent death. He joined the project on February 21, 1980, and managed to push up the promised Filmways financing from US$13 million to $15 million. Fancher's script focused more on environmental issues and less on issues of humanity and religion, which are prominent in the novel, and Scott wanted changes. Fancher found a cinema treatment by William S. Burroughs for Alan E. Nourse's novel The Bladerunner (1974), titled Blade Runner (a movie). Scott liked the name, so Deeley obtained the rights to the titles. Eventually, he hired David Peoples to rewrite the script and Fancher left the job over the issue on December 21, 1980, although he later returned to contribute additional rewrites. + +Having invested over $2.5 million in pre-production, as the date of commencement of principal photography neared, Filmways withdrew financial backing. In ten days Deeley had secured $21.5 million in financing through a three-way deal between the Ladd Company (through Warner Bros.), the Hong Kong-based producer Sir Run Run Shaw and Tandem Productions. + +Dick became concerned that no one had informed him about the film's production, which added to his distrust of Hollywood. After Dick criticized an early version of Fancher's script in an article written for the Los Angeles Select TV Guide, the studio sent Dick the Peoples rewrite. Although Dick died shortly before the film's release, he was pleased with the rewritten script and with a 20-minute special effects test reel that was screened for him when he was invited to the studio. Despite his well-known skepticism of Hollywood in principle, Dick enthused to Scott that the world created for the film looked exactly as he had imagined it. He said, "I saw a segment of Douglas Trumbull's special effects for Blade Runner on the KNBC news. I recognized it immediately. It was my own interior world. They caught it perfectly." He also approved of the film's script, saying, "After I finished reading the screenplay, I got the novel out and looked through it. The two reinforce each other so that someone who started with the novel would enjoy the movie and someone who started with the movie would enjoy the novel." The motion picture was dedicated to Dick. Principal photography of Blade Runner began on March 9, 1981, and ended four months later. + +In 1992, Ford revealed, "Blade Runner is not one of my favorite films. I tangled with Ridley." Apart from friction with the director, Ford also disliked the voiceovers: "When we started shooting it had been tacitly agreed that the version of the film that we had agreed upon was the version without voiceover narration. It was a nightmare. I thought that the film had worked without the narration. But now I was stuck re-creating that narration. And I was obliged to do the voiceovers for people that did not represent the director's interests." "I went kicking and screaming to the studio to record it." The narration monologs were written by an uncredited Roland Kibbee. + +In 2006, Scott was asked "Who's the biggest pain in the arse you've ever worked with?" He replied: "It's got to be Harrison ... he'll forgive me because now I get on with him. Now he's become charming. But he knows a lot, that's the problem. When we worked together it was my first film up and I was the new kid on the block. But we made a good movie." Ford said of Scott in 2000: "I admire his work. We had a bad patch there, and I'm over it." In 2006 Ford reflected on the production of the film saying: "What I remember more than anything else when I see Blade Runner is not the 50 nights of shooting in the rain, but the voiceover ... I was still obliged to work for these clowns that came in writing one bad voiceover after another." Ridley Scott confirmed in the summer 2007 issue of Total Film that Harrison Ford contributed to the Blade Runner Special Edition DVD, and had already recorded his interviews. "Harrison's fully on board", said Scott. + +The Bradbury Building in downtown Los Angeles served as a filming location, and a Warner Bros. backlot housed the 2019 Los Angeles street sets. Other locations included the Ennis-Brown House and the 2nd Street Tunnel. Test screenings resulted in several changes, including adding a voice-over, a happy ending, and the removal of a Holden hospital scene. The relationship between the filmmakers and the investors was difficult, which culminated in Deeley and Scott being fired but still working on the film. Crew members created T-shirts during filming saying, "Yes Guv'nor, My Ass" that mocked Scott's unfavorable comparison of U.S. and British crews; Scott responded with a T-shirt of his own, "Xenophobia Sucks", making the incident known as the T-shirt war. + +Casting + +Casting the film proved troublesome, particularly for the lead role of Deckard. Screenwriter Hampton Fancher envisioned Robert Mitchum as Deckard and wrote the character's dialogue with Mitchum in mind. Director Ridley Scott and the film's producers spent months meeting and discussing the role with Dustin Hoffman, who eventually departed over differences in vision. Harrison Ford was ultimately chosen for several reasons, including his performance in the Star Wars films, Ford's interest in the Blade Runner story, and discussions with Steven Spielberg who was finishing Raiders of the Lost Ark at the time and strongly praised Ford's work in the film. Following his success in those two films, Ford was looking for a role with dramatic depth. According to production documents, several actors were considered for the role, including Gene Hackman, Sean Connery, Jack Nicholson, Paul Newman, Clint Eastwood, Tommy Lee Jones, Arnold Schwarzenegger, Peter Falk, Nick Nolte, Al Pacino and Burt Reynolds. + +One role that was not difficult to cast was Rutger Hauer as Roy Batty, the violent yet thoughtful leader of the replicants. Scott cast Hauer without having met him, based solely on Hauer's performances in Paul Verhoeven's movies Scott had seen (Katie Tippel, Soldier of Orange, and Turkish Delight). Hauer's portrayal of Batty was regarded by Philip K. Dick as "the perfect Batty – cold, Aryan, flawless". Of the many films Hauer made, Blade Runner was his favorite. As he explained in a live chat in 2001, "Blade Runner needs no explanation. It just . All of the best. There is nothing like it. To be part of a real which changed the world's thinking. It's awesome." Hauer rewrote his character's "tears in rain" speech himself and presented the words to Scott on set prior to filming. + +Blade Runner used a number of then-lesser-known actors: Sean Young portrays Rachael, an experimental replicant implanted with the memories of Tyrell's niece, causing her to believe she is human; Nina Axelrod auditioned for the role. Daryl Hannah portrays Pris, a "basic pleasure model" replicant; Stacey Nelkin auditioned for the role, but was given another part in the film, which was ultimately cut before filming. Debbie Harry turned down the role of Pris. Casting Pris and Rachael was challenging, requiring several screen tests with Morgan Paull playing the role of Deckard. Paull was cast as Deckard's fellow bounty hunter Holden based on his performances in the tests. Brion James portrays Leon Kowalski, a combat and laborer replicant, and Joanna Cassidy portrays Zhora, an assassin replicant. + +Edward James Olmos portrays Gaff. Olmos drew on diverse ethnic sources to help create the fictional "Cityspeak" language his character uses in the film. His initial address to Deckard at the noodle bar is partly in Hungarian and means, "Horse dick [bullshit]! No way. You are the Blade ... Blade Runner." M. Emmet Walsh portrays Captain Bryant, a rumpled, hard-drinking and underhanded police veteran typical of the film noir genre. Joe Turkel portrays Dr. Eldon Tyrell, a corporate mogul who built an empire on genetically manipulated humanoid slaves. William Sanderson was cast as J. F. Sebastian, a quiet and lonely genius who provides a compassionate yet compliant portrait of humanity. J. F. sympathizes with the replicants, whom he sees as companions, and he shares their shorter lifespan due to his rapid aging disease. Joe Pantoliano had earlier been considered for the role. James Hong portrays Hannibal Chew, an elderly geneticist specializing in synthetic eyes, and Hy Pyke portrayed the sleazy bar owner Taffey Lewis – in a single take, something almost unheard-of with Scott, whose drive for perfection resulted at times in double-digit takes. + +Design + +Scott credits Edward Hopper's painting Nighthawks and the French science fiction comics magazine Métal Hurlant, to which the artist Jean "Moebius" Giraud contributed, as stylistic mood sources. He also drew on the landscape of "Hong Kong on a very bad day" and the industrial landscape of his one-time home in northeast England. The visual style of the movie is influenced by the work of futurist Italian architect Antonio Sant'Elia. Scott hired Syd Mead as his concept artist; like Scott, he was influenced by Métal Hurlant. Moebius was offered the opportunity to assist in the pre-production of Blade Runner, but he declined so that he could work on René Laloux's animated film Les Maîtres du temps – a decision that he later regretted. Production designer Lawrence G. Paull and art director David Snyder realized Scott's and Mead's sketches. Douglas Trumbull and Richard Yuricich supervised the special effects for the film, and Mark Stetson served as chief model maker. + +Blade Runner has numerous similarities to Fritz Lang's Metropolis, including a built-up urban environment, in which the wealthy literally live above the workers, dominated by a huge building – the Stadtkrone Tower in Metropolis and the Tyrell Building in Blade Runner. Special effects supervisor David Dryer used stills from Metropolis when lining up Blade Runners miniature building shots. + +The extended end scene in the original theatrical release shows Rachael and Deckard traveling into daylight with pastoral aerial shots filmed by director Stanley Kubrick. Ridley Scott contacted Kubrick about using some of his surplus helicopter aerial photography from The Shining. + +Spinner + + +"Spinner" is the generic term for the fictional flying cars used in the film. A spinner can be driven as a ground-based vehicle, and take off vertically, hover, and cruise much like vertical take-off and landing (VTOL) aircraft. They are used extensively by the police as patrol cars, and wealthy people can also acquire spinner licenses. The vehicle was conceived and designed by Syd Mead who described the spinner as an aerodyne – a vehicle which directs air downward to create lift, though press kits for the film stated that the spinner was propelled by three engines: "conventional internal combustion, jet, and anti-gravity". A spinner is on permanent exhibit at the Science Fiction and Fantasy Hall of Fame in Seattle, Washington. Mead's conceptual drawings were transformed into 25 vehicles by automobile customizer Gene Winfield; at least two were working ground vehicles, while others were light-weight mockups for crane shots and set decoration for street shots. Two of them ended up at Disney World in Orlando, Florida, but were later destroyed, and a few others remain in private collections. + +Voight-Kampff machine + +The Voight-Kampff machine is a fictional interrogation tool, originating from the novel (where it is spelled "Voigt-Kampff"). The Voight-Kampff is a polygraph-like machine used by blade runners to determine whether an individual is a replicant. It measures bodily functions such as respiration, blush response, heart rate and eye movement in response to questions dealing with empathy. + +Music + +The Blade Runner soundtrack by Vangelis is a dark melodic combination of classic composition and futuristic synthesizers which mirrors the film noir retro-future envisioned by Scott. Vangelis, fresh from his Academy Award-winning score for Chariots of Fire, composed and performed the music on his synthesizers. He also made use of various chimes and the vocals of collaborator Demis Roussos. Another memorable sound is the tenor sax solo "Love Theme" by British saxophonist Dick Morrissey, who performed on many of Vangelis's albums. Ridley Scott also used "Memories of Green" from the Vangelis album See You Later, an orchestral version of which Scott would later use in his film Someone to Watch Over Me. + +Along with Vangelis's compositions and ambient textures, the film's soundscape also features a track by the Japanese ensemble Nipponia – "Ogi no Mato" or "The Folding Fan as a Target" from the Nonesuch Records release Traditional Vocal and Instrumental Music – and a track by harpist Gail Laughton from "Harps of the Ancient Temples" on Laurel Records. + +Despite being well received by fans and critically acclaimed and nominated in 1982 for a BAFTA and a Golden Globe as best original score, and the promise of a soundtrack album from Polydor Records in the end titles of the film, the release of the official soundtrack recording was delayed for over a decade. There are two official releases of the music from Blade Runner. In light of the lack of a release of an album, the New American Orchestra recorded an orchestral adaptation in 1982 which bore little resemblance to the original. Some of the film tracks would, in 1989, surface on the compilation Vangelis: Themes, but not until the 1992 release of the Director's Cut version would a substantial amount of the film's score see commercial release. + +These delays and poor reproductions led to the production of many bootleg recordings over the years. A bootleg tape surfaced in 1982 at science fiction conventions and became popular given the delay of an official release of the original recordings, and in 1993 "Off World Music, Ltd" created a bootleg CD that would prove more comprehensive than Vangelis' official CD in 1994. A set with three CDs of Blade Runner-related Vangelis music was released in 2007. Titled Blade Runner Trilogy, the first disc contains the same tracks as the 1994 official soundtrack release, the second features previously unreleased music from the movie, and the third disc is all newly composed music from Vangelis, inspired by, and in the spirit of the movie. + +Special effects + +The film's special effects are generally recognized to be among the best in the genre, using the available (non-digital) technology to the fullest. Special effects engineers who worked on the film are often praised for the innovative technology they used to produce and design certain aspects of those visuals. In addition to matte paintings and models, the techniques employed included multipass exposures. In some scenes, the set was lit, shot, the film rewound, and then rerecorded over with different lighting. In some cases this was done 16 times in all. The cameras were frequently motion controlled using computers. Many effects used techniques which had been developed during the production of Close Encounters of the Third Kind. + +Release + +Theatrical run + +Blade Runner was released in 1,290 theaters on June 25, 1982. That date was chosen by producer Alan Ladd Jr. because his previous highest-grossing films (Star Wars and Alien) had a similar opening date (May 25) in 1977 and 1979, making the 25th of the month his "lucky day". Blade Runner grossed reasonably good ticket sales in its opening weekend; earning $6.1 million during its first weekend in theaters. The film was released close to other major science-fiction and fantasy releases such as The Thing, Star Trek II: The Wrath of Khan, Conan the Barbarian and E.T. the Extra-Terrestrial, which affected its commercial success. + +Versions + +Several versions of Blade Runner have been shown. The original workprint version (1982, 113 minutes) was shown for audience test previews in Denver and Dallas in March 1982. Negative responses to the previews led to the modifications resulting in the U.S. theatrical version. The workprint was shown as a director's cut without Scott's approval at the Los Angeles Fairfax Theater in May 1990, at an AMPAS showing in April 1991, and in September and October 1991 at the Los Angeles NuArt Theater and the San Francisco Castro Theatre. Positive responses pushed the studio to approve work on an official director's cut. A San Diego Sneak Preview was shown only once, in May 1982, and was almost identical to the U.S. theatrical version but contained three extra scenes not shown in any other version, including the 2007 Final Cut. + +Two versions were shown in the film's 1982 theatrical release: the U.S. theatrical version (117 minutes), known as the original version or Domestic Cut (released on Betamax, CED Videodisc and VHS in 1983, and on LaserDisc in 1987), and the International Cut (117 minutes), also known as the "Criterion Edition" or "uncut version", which included more violent action scenes than the U.S. version. Although initially unavailable in the U.S. and distributed in Europe and Asia via theatrical and local Warner Home Video releases, the International Cut was later released on VHS and The Criterion Collection Laserdisc in North America, and re-released in 1992 as a "10th Anniversary Edition". + +Ridley Scott's Director's Cut (1992, 116 minutes) had significant changes from the theatrical version including the removal of Deckard's voice-over, the re-insertion of the unicorn sequence, and the removal of the studio-imposed happy ending. Scott provided extensive notes and consultation to Warner Bros. through film preservationist Michael Arick, who was put in charge of creating the Director's Cut. + +Scott's definitive The Final Cut (2007, 117 minutes) was released by Warner Bros. theatrically on October 5, 2007, and subsequently released on DVD, HD DVD, and Blu-ray Disc in December 2007. This is the only version over which Scott had complete artistic and editorial control. + +Reception + +Critical response + +On Rotten Tomatoes, the film holds an 88% approval rating based on 130 reviews, with an average rating of 8.50/10. The website's critics consensus reads, "Misunderstood when it first hit theaters, the influence of Ridley Scott's mysterious, neo-noir Blade Runner has deepened with time. A visually remarkable, achingly human sci-fi masterpiece." Metacritic, which uses a weighted average, assigned the film a score of 84 out of 100 based on 15 critics, indicating "universal acclaim". + +Initial reactions among film critics were mixed. Some wrote that the plot took a back seat to the film's special effects and did not fit the studio's marketing as an action and adventure film. Others acclaimed its complexity and predicted it would stand the test of time. Negative criticism in the United States cited its slow pace. Sheila Benson from the Los Angeles Times called it "Blade Crawler", and Pat Berman in The State and Columbia Record described it as "science fiction pornography". Pauline Kael praised Blade Runner as worthy of a place in film history for its distinctive sci-fi vision, yet criticized the film's lack of development in "human terms". Ares magazine said, "Misunderstood by audiences and critics alike, it is by far the best science fiction film of the year." + +Cultural analysis +Academics began analyzing the film almost as soon as it was released. One of the first books on the film was Paul M. Sammon's Future Noir: The Making of Blade Runner (1996), which dissects all the details concerning the film making. He was followed by Scott Bukatman's Blade Runner and other books and academic articles. In Postmodern Metanarratives: Blade Runner and Literature in the Age of Image, Décio Torres Cruz analyzes the philosophical and psychological issues and the literary influences in Blade Runner. He examines the film's cyberpunk and dystopic elements by establishing a link between the Biblical, classical and modern traditions and the postmodern aspects in the film's collage of several literary texts. + +The boom in home video formats helped establish a growing cult around the film, which scholars have dissected for its dystopic aspects, questions regarding "authentic" humanity, ecofeminist aspects and use of conventions from multiple genres. Popular culture began to reassess its impact as a classic several years after it was released. Roger Ebert praised the visuals of both the original and the Director's Cut and recommended it for that reason; however, he found the human story clichéd and a little thin. He later added The Final Cut to his "Great Movies" list. Critic Chris Rodley and Janet Maslin theorized that Blade Runner changed cinematic and cultural discourse through its image repertoire and subsequent influence on films. In 2012, Time film critic Richard Corliss surgically analyzed the durability, complexity, screenplay, sets and production dynamics from a personal, three-decade perspective. Denis Villeneuve, who directed the sequel, Blade Runner 2049, cites the film as a huge influence for him and many others. + +It has also been noted for its postmodernist approach and that it contributes to the historical development of modern dystopia in film. Furthermore, the futuristic version of Los Angeles has been widely discussed by academics with some comparing it to Milton's descriptions of hell in Paradise Lost. A 2019 retrospective in the BBC argued that elements of the film's socio-political themes remained prescient in the real year of the film's setting, such as its depiction of climate change. From a more philosophical perspective, Alison Landsberg described Scott's direction of the film as a "prosthetic memory"—an action that has never happened and appears to be divorced from lived experience, yet it defines personhood and identity within the wider Blade Runner universe. + +Awards and nominations + +Blade Runner won or received nominations for the following awards: + +Themes + +The film operates on multiple dramatic and narrative levels. It employs some of the conventions of film noir, among them the character of a femme fatale; narration by the protagonist (in the original release); chiaroscuro cinematography; and giving the hero a questionable moral outlook – extended to include reflections upon the nature of his own humanity. It is a literate science fiction film, thematically enfolding the philosophy of religion and moral implications of human mastery of genetic engineering in the context of classical Greek drama and hubris. It also draws on Biblical images, such as Noah's flood, and literary sources, such as Frankenstein and William Blake. Although Scott said any similarity was merely coincidental, fans claimed that the chess game between Sebastian and Tyrell was based on the famous Immortal Game of 1851. + +Blade Runner delves into the effects of technology on the environment and society by reaching to the past, using literature, religious symbolism, classical dramatic themes, and film noir techniques. This tension between past, present, and future is represented in the "retrofitted" future depicted in the film, one which is high-tech and gleaming in places but decayed and outdated elsewhere. In an interview with The Observer in 2002, director Ridley Scott described the film as "extremely dark, both literally and metaphorically, with an oddly masochistic feel". He also said that he "liked the idea of exploring pain" in the wake of his brother's death: "When he was ill, I used to go and visit him in London, and that was really traumatic for me." + +A sense of foreboding and paranoia pervades the world of the film: corporate power looms large; the police seem omnipresent; vehicle and warning lights probe into buildings; and the consequences of huge biomedical power over the individual are explored – +especially regarding replicants' implanted memories. The film depicts a world post ecocide, where warfare and capitalism have led to destruction of 'normal' ecological systems. Control over the environment is exercised on a vast scale, and goes hand in hand with the absence of any natural life; for example, artificial animals stand in for their extinct predecessors. This oppressive backdrop explains the frequently referenced migration of humans to "off-world" (extraterrestrial) colonies. Eyes are a recurring motif, as are manipulated images, calling into question the nature of reality and our ability to accurately perceive and remember it. + +These thematic elements provide an atmosphere of uncertainty for Blade Runners central theme of examining humanity. In order to discover replicants, an empathy test is used, with a number of its questions focused on the treatment of animals – seemingly an essential indicator of one's "humanity". Replicants will not respond the same way humans would, showing a lack of concern. The film goes so far as to question if Deckard might be a replicant, in the process asking the audience to re-evaluate what it means to be human. + +The question of whether Deckard is intended to be a human or a replicant has been an ongoing controversy since the film's release. Both Michael Deeley and Harrison Ford wanted Deckard to be human, while Hampton Fancher preferred ambiguity. Ridley Scott has stated that in his vision, Deckard is a replicant. Deckard's unicorn-dream sequence, inserted into Scott's Director's Cut and concomitant with Gaff's parting gift of an origami unicorn, is seen by many as showing that Deckard is a replicant – because Gaff could have retrieved Deckard's implanted memories. The interpretation that Deckard is a replicant is challenged by others who believe the unicorn imagery shows that the characters, whether human or replicant, share the same dreams and recognize their affinity, or that the absence of a decisive answer is crucial to the film's main theme. The film's inherent ambiguity and uncertainty, as well as its textual richness, have permitted multiple interpretations. + +Legacy + +Cultural impact + +While not initially a success with North American audiences, Blade Runner was popular internationally and garnered a cult following. The film's dark style and futuristic designs have served as a benchmark and its influence can be seen in many subsequent science fiction films, video games, anime, and television programs. For example, Ronald D. Moore and David Eick, the producers of the re-imagining of Battlestar Galactica, have both cited Blade Runner as one of the major influences for the show. + +The film was selected for preservation in the United States National Film Registry in 1993 and is frequently taught in university courses. In 2007, it was named the second-most visually influential film of all time by the Visual Effects Society. The film has also been the subject of parody, such as the comics Blade Bummer by Crazy comics, Bad Rubber by Steve Gallacci, and the Red Dwarf 2009 three-part miniseries "Back to Earth". The anime series Psycho-Pass by Production I.G was also highly influenced by the movie. + +Blade Runner continues to reflect modern trends and concerns, and an increasing number of critics consider it one of the greatest science fiction films of all time. It was voted the best science fiction film ever made in a 2004 poll of 60 eminent world scientists. Blade Runner is also cited as an important influence to both the style and story of the Ghost in the Shell franchise, which itself has been highly influential to the future-noir genre. Blade Runner has been very influential to the cyberpunk movement. It also influenced the cyberpunk derivative biopunk, which revolves around biotechnology and genetic engineering. + +The dialogue and music in Blade Runner has been sampled in music more than any other film of the 20th century. The 2009 album I, Human by Singaporean band Deus Ex Machina makes numerous references to the genetic engineering and cloning themes from the film, and even features a track titled "Replicant". + +Blade Runner is cited as a major influence on Warren Spector, designer of the video game Deus Ex, which displays evidence of the film's influence in both its visual rendering and plot. Indeed, the film's look – and in particular its overall darkness, preponderance of neon lights and opaque visuals – are easier to render than complicated backdrops, making it a popular reference point for video game designers. It has influenced adventure games such as the 2012 graphical text adventure Cypher, Rise of the Dragon, Snatcher, the Tex Murphy series, Beneath a Steel Sky, Flashback: The Quest for Identity, Bubblegum Crisis video games (and their original anime), the role-playing game Shadowrun, the first-person shooter Perfect Dark, the shooter game Skyhammer, and the Syndicate series of video games. + +The logos of Atari, Bell, Coca-Cola, Cuisinart, Pan Am, and RCA, all market leaders at the time, were prominently displayed as product placement in the film, and all experienced setbacks after the film's release, leading to suggestions of a Blade Runner curse. Coca-Cola and Cuisinart recovered, and Tsingtao beer was also featured in the film and was more successful after the film than before. + +The design of Tesla's Cybertruck was inspired by the film. Prior to its release Elon Musk promised that it would "look like something out of Blade Runner". Besides referring to the truck as the "Blade Runner Truck", Musk chose to debut the truck in order to coincide with the film's setting of November 2019. The film's art designer Syd Mead praised the truck and said he was "flattered" by the homage to Blade Runner. + +Media recognition + +American Film Institute recognition + + AFI's 100 Years...100 Thrills – No. 74 + AFI's 100 Years...100 Movies (10th Anniversary Edition) – No. 97 + AFI's 10 Top 10 – No. 6 Science Fiction Film + +In other media + +Before filming began, Cinefantastique magazine commissioned Paul M. Sammon to write a special issue about Blade Runners production which became the book Future Noir: The Making of Blade Runner. The book chronicles Blade Runners evolution, focusing on film-set politics, especially the British director's experiences with his first American film crew; of which producer Alan Ladd, Jr. has said, "Harrison wouldn't speak to Ridley and Ridley wouldn't speak to Harrison. By the end of the shoot Ford was 'ready to kill Ridley', said one colleague. He really would have taken him on if he hadn't been talked out of it." Future Noir has short cast biographies and quotations about their experiences as well as photographs of the film's production and preliminary sketches. A second edition of Future Noir was published in 2007, and additional materials not in either print edition have been published online. + +Philip K. Dick refused a $400,000 offer to write a Blade Runner novelization, saying: "[I was] told the cheapo novelization would have to appeal to the twelve-year-old audience" and it "would have probably been disastrous to me artistically". He added, "That insistence on my part of bringing out the original novel and not doing the novelization – they were just furious. They finally recognized that there was a legitimate reason for reissuing the novel, even though it cost them money. It was a victory not just of contractual obligations but of theoretical principles." Do Androids Dream of Electric Sheep? was eventually reprinted as a tie-in, with the film poster as a cover and the original title in parentheses below the Blade Runner title. Additionally, a novelization of the movie entitled Blade Runner: A Story of the Future by Les Martin was released in 1982. Archie Goodwin scripted the comic book adaptation, A Marvel Comics Super Special: Blade Runner, published in September 1982, which was illustrated by Al Williamson, Carlos Garzon, Dan Green, and Ralph Reese, and lettered by Ed King. + +Blue Dolphin Enterprises published the film's screenplay combined with selected production storyboards as The Illustrated Blade Runner (June 1982); a book of original production artwork by Syd Mead, Mentor Huebner, Charles Knode, Michael Kaplan, and Ridley Scott as Blade Runner Sketchbook (1982); and The Blade Runner Portfolio (1982), a collection of twelve photographic prints, similar to the artist portfolios released by their Schanes & Schanes imprint. + +There are two video games based on the film, both titled Blade Runner: one from 1985, a side-scrolling video game for Commodore 64, ZX Spectrum, and Amstrad CPC by CRL Group PLC, which is marked as "a video game interpretation of the film score by Vangelis" rather than of the film itself (due to licensing issues); and another from 1997, a point-and-click adventure for PC by Westwood Studios. The 1997 game has a non-linear plot based in the Blade Runner world, non-player characters that each ran in their own independent AI, and an unusual pseudo-3D engine (which eschewed polygonal solids in favor of voxel elements) that did not require the use of a 3D accelerator card to play the game. Eldon Tyrell, Gaff, Leon, Rachael, Chew, J. F. Sebastian and Howie Lee appear, and their voice files are recorded by the original actors, with the exception of Gaff, who is replaced by Javier Grajeda (as Victor Gardell) and Howie Lee, who is replaced by Toru Nagai. The player assumes the role of McCoy, another replicant-hunter working at the same time as Deckard. + +The television film (and later series) Total Recall 2070 was initially planned as a spin-off of the film Total Recall (based on Philip K. Dick's short story "We Can Remember It for You Wholesale"), but was produced as a hybrid of Total Recall and Blade Runner. Many similarities between Total Recall 2070 and Blade Runner were noted, as well as apparent influences on the show from Isaac Asimov's The Caves of Steel and the TV series Holmes & Yoyo. + +Documentaries + +The film has been the subject of several documentaries. + + Blade Runner: Convention Reel (1982, 13 minutes) + Co-directed by Muffet Kaufman and Jeffrey B. Walker, shot and screened in 16 mm, featured no narrator, was filmed in 1981 while Blade Runner was still in production and featured short "behind-the-scenes" segments showing sets being built and sequences being shot, as well as interviews with Ridley Scott, Syd Mead and Douglas Trumbull.

Its source material comprises more than 80 interviews, including extensive conversations with Ford, Young, and Scott. The documentary is presented in eight chapters, with each of the first seven covering a portion of the filmmaking process. The final chapter examines Blade Runner's controversial legacy. + All Our Variant Futures: From Workprint to Final Cut (2007, 29 minutes) + Produced by Paul Prischman, appears on the Blade Runner Ultimate Collector's Edition and provides an overview of the film's multiple versions and their origins, as well as detailing the seven-year-long restoration, enhancement and remastering process behind The Final Cut. + Blade Runner Phenomenon (2021, 53 minutes) + Directed by Boris Hars-Tschachotin and made by the France and Germany European public service channel ARTE, this documentary informs viewers using behind-the-scenes material from various sets, photos, original locations in Los Angeles, and interviews with those involved in the production. + +Sequel and related media + +A sequel was released in 2017, titled Blade Runner 2049, with Ryan Gosling alongside Ford in the starring roles. It entered production in mid-2016 and is set decades after the first film. Harrison Ford reprised his role as Rick Deckard. The film won two Academy Awards, for cinematography and visual effects. + +The world of Blade Runner has also come to be explored in animation. Blade Runner 2049 was preceded by the release of three short films that served as prequels, where the chronological first, Blade Runner Black Out 2022, was anime (the other two, 2036: Nexus Dawn and 2048: Nowhere to Run, were live action, not animated). + +In November 2021, a Japanese-American anime television series called Blade Runner: Black Lotus was released. The series tells the story of a female replicant protagonist, rather than that of a male Blade Runner one. + +Dick's friend K. W. Jeter wrote three authorized Blade Runner novels that continue Rick Deckard's story, attempting to resolve the differences between the film and Do Androids Dream of Electric Sheep? These are Blade Runner 2: The Edge of Human (1995), Blade Runner 3: Replicant Night (1996), and Blade Runner 4: Eye and Talon (2000) + +Blade Runner cowriter David Peoples wrote the 1998 action film Soldier, which he referred to as a "sidequel" or spiritual successor to the original film; the two are set in a shared universe.

During his career at Microsoft, Gates held the positions of chairman, chief executive officer (CEO), president, and chief software architect, while also being its largest individual shareholder until May 2014. He was a major entrepreneur of the microcomputer revolution of the 1970s and 1980s. + +Gates was born and raised in Seattle, Washington. In 1975, he and Allen founded Microsoft in Albuquerque, New Mexico. It later became the world's largest personal computer software company. Gates led the company as its chairman and chief executive officer until stepping down as CEO in January 2000, succeeded by Steve Ballmer, but he remained chairman of the board of directors and became chief software architect. During the late 1990s, he was criticized for his business tactics, which were considered anti-competitive. This opinion has been upheld by numerous court rulings. In June 2008, Gates transitioned into a part-time role at Microsoft and full-time work at the Bill & Melinda Gates Foundation, the private charitable foundation he and his then-wife Melinda had established in 2000. He stepped down as chairman of the Microsoft board in February 2014 and assumed the role of technology adviser to support newly appointed CEO Satya Nadella. In March 2020, Gates left his board positions at Microsoft and Berkshire Hathaway to focus on his philanthropic efforts on climate change, global health and development, and education. + +Since 1987, Gates has been included in the Forbes list of the world's billionaires. From 1995 to 2017, he held the Forbes title of the richest person in the world every year except in 2008 and from 2010 to 2013. In October 2017, he was surpassed by Amazon founder and CEO Jeff Bezos, who had an estimated net worth of US$90.6 billion compared to Gates's net worth of US$89.9 billion at the time. In the Forbes 400 list of wealthiest Americans in 2023, he was ranked 6th with a wealth of $111.0 billion. As of October 2023, Gates has an estimated net worth of US$123 billion, making him the fourth-richest person in the world according to Bloomberg Billionaires Index. + +Later in his career and since leaving day-to-day operations at Microsoft in 2008, Gates has pursued other business and philanthropic endeavors. He is the founder and chairman of several companies, including BEN, Cascade Investment, TerraPower, bgC3, and Breakthrough Energy. He has donated sizable amounts of money to various charitable organizations and scientific research programs through the Bill & Melinda Gates Foundation, reported to be the world's largest private charity. Through the foundation, he led an early 21st century vaccination campaign that significantly contributed to the eradication of the wild poliovirus in Africa. In 2010, Gates and Warren Buffett founded The Giving Pledge, whereby they and other billionaires pledge to give at least half of their wealth to philanthropy. + +Early life +William Henry Gates III was born on October 28, 1955, in Seattle, Washington as the only son of William H. Gates Sr. (1925–2020) and his first wife, Mary Maxwell Gates (1929–1994). His ancestry includes English, German, and Irish/Scots-Irish. His father was a prominent lawyer, and his mother served on the board of directors of First Interstate BancSystem and United Way of America. Gates's maternal grandfather was J. W. Maxwell, a national bank president. Gates has an older sister Kristi (Kristianne) and a younger sister Libby. He is the fourth of his name in his family but is known as William Gates III or "Trey" (i.e., three) because his father had the "II" suffix. The family lived in the Sand Point area of Seattle in a home that was damaged by a rare tornado when Gates was seven years old. + +According to Gates, when he was young, his parents wanted him to pursue a career in law. During his childhood, his family regularly attended a church of the Congregational Christian Churches, a Protestant Reformed denomination. Gates was small for his age and was bullied as a child. The family encouraged competition; one visitor reported that "it didn't matter whether it was hearts or pickleball or swimming to the dock; there was always a reward for winning and there was always a penalty for losing". + +At age 13, he enrolled in the private Lakeside prep school, where he wrote his first software program. When he was in eighth grade, the Mothers' Club at the school used proceeds from Lakeside School's rummage sale to buy a Teletype Model 33 ASR terminal and a block of computer time on a General Electric (GE) computer for the students. Gates took an interest in programming the GE system in BASIC, and he was excused from math classes to pursue his interest. He wrote his first computer program on this machine, an implementation of tic-tac-toe that allowed users to play games against the computer. Gates was fascinated by the machine and how it would always execute software code perfectly. After the Mothers Club donation was exhausted, Gates and other students sought time on systems including DEC PDP minicomputers. One of these systems was a PDP-10 belonging to Computer Center Corporation (CCC) which banned Gates, Paul Allen, Ric Weiland, and Gates's best friend and first business partner Kent Evans for the summer after it caught them exploiting bugs in the operating system to obtain free computer time. + +The four students formed the Lakeside Programmers Club to make money. At the end of the ban, they offered to find bugs in CCC's software in exchange for extra computer time. Rather than using the system remotely via Teletype, Gates went to CCC's offices and studied source code for various programs that ran on the system, including Fortran, Lisp, and machine language. The arrangement with CCC continued until 1970 when the company went out of business. + +The following year, a Lakeside teacher enlisted Gates and Evans to automate the school's class-scheduling system, providing them computer time and royalties in return. The duo worked diligently in order to have the program ready for their senior year. Towards the end of their junior year, Evans was killed in a mountain climbing accident, which Gates has described as one of the saddest days of his life. Gates then turned to Allen who helped him finish the system for Lakeside. + +At 17, Gates formed a venture with Allen called Traf-O-Data to make traffic counters based on the Intel 8008 processor. In 1972, he served as a congressional page in the House of Representatives. He was a National Merit Scholar when he graduated from Lakeside School in 1973. He scored 1590 out of 1600 on the Scholastic Aptitude Tests (SAT) and enrolled at Harvard College in the autumn of 1973. He chose a pre-law major but took mathematics (including Math 55) and graduate level computer science courses. While at Harvard, he met fellow student and future Microsoft CEO Steve Ballmer. Gates left Harvard after two years while Ballmer stayed and graduated magna cum laude. Years later, Ballmer later succeeded Gates as Microsoft's CEO and maintained that position from 2000 until his resignation in 2014. + +Gates devised an algorithm for pancake sorting as a solution to one of a series of unsolved problems presented in a combinatorics class by professor Harry Lewis. His solution held the record as the fastest version for over 30 years, and its successor is faster by only 2%. His solution was formalized and published in collaboration with Harvard computer scientist Christos Papadimitriou. + +Gates remained in contact with Paul Allen and joined him at Honeywell during the summer of 1974. In 1975, the MITS Altair 8800 was released based on the Intel 8080 CPU, and Gates and Allen saw the opportunity to start their own computer software company. Gates dropped out of Harvard that same year. His parents were supportive of him after seeing how much he wanted to start his own company. He explained his decision to leave Harvard: "if things hadn't worked out, I could always go back to school. I was officially on leave." + +Microsoft + +BASIC + +Gates read the January 1975 issue of Popular Electronics which demonstrated the Altair 8800, and contacted Micro Instrumentation and Telemetry Systems (MITS) to inform them that he and others were working on a BASIC interpreter for the platform. In reality, Gates and Allen did not have an Altair and had not written code for it; they merely wanted to gauge MITS's interest. MITS president Ed Roberts agreed to meet them for a demonstration, and over the course of a few weeks they developed an Altair emulator that ran on a minicomputer, and then the BASIC interpreter. The demonstration was held at MITS's offices in Albuquerque, New Mexico; it was a success and resulted in a deal with MITS to distribute the interpreter as Altair BASIC. MITS hired Allen, and Gates took a leave of absence from Harvard to work with him at MITS in November 1975. Allen named their partnership "Micro-Soft", a combination of "microcomputer" and "software", and their first office was in Albuquerque. The first employee Gates and Allen hired was their high school collaborator Ric Weiland. They dropped the hyphen within a year and officially registered the trade name "Microsoft" with the Secretary of the State of New Mexico on November 26, 1976. Gates never returned to Harvard to complete his studies. + +Microsoft's Altair BASIC was popular with computer hobbyists, but Gates discovered that a pre-market copy had leaked out and was being widely copied and distributed. In February 1976, he wrote an Open Letter to Hobbyists in the MITS newsletter in which he asserted that more than 90% of the users of Microsoft Altair BASIC had not paid Microsoft for it and the Altair "hobby market" was in danger of eliminating the incentive for any professional developers to produce, distribute, and maintain high-quality software. This letter was unpopular with many computer hobbyists, but Gates persisted in his belief that software developers should be able to demand payment. Microsoft became independent of MITS in late 1976, and it continued to develop programming language software for various systems. The company moved from Albuquerque to Bellevue, Washington on January 1, 1979. + +Gates said he personally reviewed and often rewrote every line of code that the company produced in its first five years. As the company grew, he transitioned into a manager role, then an executive. + +DONKEY.BAS, is a computer game written in 1981 and included with early versions of the PC DOS operating system distributed with the original IBM PC. It is a driving game in which the player must avoid hitting donkeys. The game was written by Gates and Neil Konzen. + +IBM partnership +IBM, the leading supplier of computer equipment to commercial enterprises at the time, approached Microsoft in July 1980 concerning software for its upcoming personal computer, the IBM PC, after Gates's mother, Mary Maxwell Gates, mentioned Microsoft to John Opel, IBM's then CEO. IBM first proposed that Microsoft write the BASIC interpreter. IBM's representatives also mentioned that they needed an operating system, and Gates referred them to Digital Research (DRI), makers of the widely used CP/M operating system. IBM's discussions with Digital Research went poorly, however, and they did not reach a licensing agreement. IBM representative Jack Sams mentioned the licensing difficulties during a subsequent meeting with Gates and asked if Microsoft could provide an operating system. A few weeks later, Gates and Allen proposed using 86-DOS, an operating system similar to CP/M, that Tim Paterson of Seattle Computer Products (SCP) had made for hardware similar to the PC. Microsoft made a deal with SCP to be the exclusive licensing agent of 86-DOS, and later the full owner. Microsoft employed Paterson to adapt the operating system for the PC and delivered it to IBM as PC DOS for a one-time fee of $50,000. + +The contract itself only earned Microsoft a relatively small fee. It was the prestige brought to Microsoft by IBM's adoption of their operating system that would be the origin of Microsoft's transformation from a small business to the leading software company in the world. Gates had not offered to transfer the copyright on the operating system to IBM because he believed that other personal computer makers would clone IBM's PC hardware. They did, making the IBM-compatible PC, running DOS, a de facto standard. The sales of MS-DOS (the version of DOS sold to customers other than IBM) made Microsoft a major player in the industry. The press quickly identified Microsoft as being very influential on the IBM PC. PC Magazine asked if Gates was "the man behind the machine?". + +Gates oversaw Microsoft's company restructuring on June 25, 1981, which re-incorporated the company in Washington state and made Gates the president and chairman of the board, with Paul Allen as vice president and vice chairman. In early 1983, Allen left the company after receiving a Hodgkin lymphoma diagnosis, effectively ending the formal business partnership between Gates and Allen, which had been strained months prior due to a contentious dispute over Microsoft equity. Later in the decade, Gates repaired his relationship with Allen and together the two donated millions to their childhood school Lakeside. They remained friends until Allen's death in October 2018. + +Windows +Microsoft and Gates launched their first retail version of Microsoft Windows on November 20, 1985, in an attempt to fend off competition from Apple's Macintosh GUI, which had captivated consumers with its simplicity and ease of use. In August 1986, the company struck a deal with IBM to develop a separate operating system called OS/2. Although the two companies successfully developed the first version of the new system, the partnership deteriorated due to mounting creative differences. The operating system grew out of DOS in an organic fashion over a decade until Windows 95, which hid the DOS prompt by default. Windows XP was released one year after Gates stepped down as Microsoft CEO. Windows 8.1 was the last version of the OS released before Gates left the chair of the firm to John W. Thompson on February 5, 2014. + +Management style + +During Microsoft's early years, Gates was an active software developer, particularly in the company's programming language products, but his primary role in most of the company's history was as a manager and executive. He has not officially been on a development team since working on the TRS-80 Model 100, but he wrote code that shipped with the company's products as late as 1989. Jerry Pournelle wrote in 1985 when Gates announced Microsoft Excel: "Bill Gates likes the program, not because it's going to make him a lot of money (although I'm sure it will do that), but because it's a neat hack." + +On June 15, 2006, Gates announced that he would transition out of his role at Microsoft to dedicate more time to philanthropy. He gradually divided his responsibilities between two successors when he placed Ray Ozzie in charge of management and Craig Mundie in charge of long-term product strategy. The process took two years to fully transfer his duties to Ozzie and Mundie, and was completed on June 27, 2008. + +Post-Microsoft +Since leaving day-to-day operations at Microsoft, Gates has continued his philanthropy and works on other projects. + +According to the Bloomberg Billionaires Index, Gates was the world's highest-earning billionaire in 2013, as his net worth increased by US$15.8 billion to US$78.5 billion. , most of Gates's assets are held in Cascade Investment LLC, an entity through which he owns stakes in numerous businesses, including Four Seasons Hotels and Resorts, and Corbis Corp. On February 4, 2014, Gates stepped down as chairman of Microsoft to become "technology advisor" at the firm to support newly appointed CEO Satya Nadella. + +Gates provided his perspective on a range of issues in a substantial interview that was published in the March 27, 2014, issue of Rolling Stone magazine. In the interview, Gates provided his perspective on climate change, his charitable activities, various tech companies and people involved in them, and the state of America. In response to a question about his greatest fear when he looks 50 years into the future, Gates stated: "there'll be some really bad things that'll happen in the next 50 or 100 years, but hopefully none of them on the scale of, say, a million people that you didn't expect to die from a pandemic, or nuclear or bioterrorism." Gates also identified innovation as the "real driver of progress" and pronounced that "America's way better today than it's ever been." + +Gates has often expressed concern about the potential harms of superintelligence; in a Reddit "ask me anything", he stated that: + +In an interview that was held at the TED conference in March 2015, with Baidu co-founder and CEO, Robin Li, Gates said he would "highly recommend" Nick Bostrom's recent work, Superintelligence: Paths, Dangers, Strategies. During the conference, Gates warned that the world was not prepared for the next pandemic, a situation that would come to pass in late 2019 when the COVID-19 pandemic began. In March 2018, Gates met at his home in Seattle with Mohammed bin Salman, the reformist crown prince and de facto ruler of Saudi Arabia to discuss investment opportunities for Saudi Vision 2030. In June 2019, Gates admitted that losing the mobile operating system race to Android was his biggest mistake. He stated that it was within their skill set of being the dominant player, but partially blames the antitrust litigation during the time. That same year, Gates became an advisory board member of the Bloomberg New Economy Forum. + +On March 13, 2020, Microsoft announced Gates would be leaving his board positions at Berkshire Hathaway and Microsoft to dedicate himself to philanthropic endeavors such as climate change, global health and development, and education. + +During the COVID-19 pandemic, Gates has widely been looked at by media outlets as an expert on the issue, despite him not being a public official or having any prior medical training. His foundation did, however, establish the COVID-19 Therapeutics Accelerator in 2020 to hasten the development and evaluation of new and repurposed drugs and biologics to treat patients for COVID-19, and, as of February 2021, Gates expressed that he and Anthony Fauci frequently talk and collaborate on matters including vaccines and other medical innovations to fight the pandemic. + +Business ventures and investments (partial list) +Gates has a multi-billion dollar investment portfolio with stakes in companies in various sectors and has participated in several entrepreneurial ventures beyond Microsoft, including: + AutoNation, an automotive retailer which trades on the NYSE and in which Gates has a 16% stake. + bgC3 LLC, a think-tank and research company founded by Gates. + Canadian National Railway (CN), a Canadian Class I freight railway. As of 2019, Gates is the single largest shareholder of the company. + Cascade Investment LLC, a private investment and holding company incorporated in the United States, founded and controlled by Gates and headquartered in Kirkland, Washington. +Gates is the largest private owner of farmland in the United States with his landholdings owned through Cascade Investment totalling 242,000 acres across 19 states. He is the 49th largest private owner of land in the US. + Carbon Engineering, a for-profit venture founded by David Keith, which Gates helped fund. It is also supported by Chevron Corporation and Occidental Petroleum. + SCoPEx, Keith's academic venture in "sun-dimming" geoengineering, which Gates provided most of the $12 million for. + Corbis (originally named Interactive Home Systems and now known as Branded Entertainment Network), a digital image licensing and rights services company founded and chaired by Gates. + EarthNow, a Seattle-based startup company aiming to blanket the Earth with live satellite video coverage. Gates is a large financial backer. + Eclipse Aviation, a defunct manufacturer of very light jets. Gates was a major stake-holder early on in the project. + Impossible Foods, a company that develops plant-based substitutes for meat products. Some of the $396 million Patrick O. Brown collected for his business came from Gates around 2014 to 2017. + Ecolab, a global provider of water, hygiene and energy technologies and services to the food, energy, healthcare, industrial and hospitality markets. Combined with the shares owned by the Foundation, Gates owns 11.6% of the company. A shareholder agreement in 2012 allowed him to own up to 25% of the company, but this agreement was removed. + ResearchGate, a social networking site for scientists. Gates participated in a $35 million round of financing along with other investors. + TerraPower, a nuclear reactor design company co-founded and chaired by Gates, which is developing next generation traveling-wave reactor nuclear power plants in an effort to tackle climate change. + Breakthrough Energy Ventures, a closed fund for wealthy individuals who seek ROI on a 20-year horizon (see next section), which "is funding green start-ups and a host of other low-carbon entrepreneurial projects, including everything from advanced nuclear technology to synthetic breast milk." It was founded by Gates in 2015. + Ginkgo Bioworks, a biotech startup that received $350 million in venture funding in 2019, in part from Gates's investment firm Cascade Investment. + Luminous Computing, a company that develops neuromorphic photonic integrated circuits for AI acceleration. + Mologic, a British diagnostic technology company that Gates purchased, along with the Soros Economic Development Fund, "which has developed 10-minute Covid lateral flow tests that it aims to make for as little as $1." + +Climate change and energy + +Gates considers climate change and global access to energy to be critical, interrelated issues. He has urged governments and the private sector to invest in research and development to make clean, reliable energy cheaper. Gates envisions that a breakthrough innovation in sustainable energy technology could drive down both greenhouse gas emissions and poverty, and bring economic benefits by stabilizing energy prices. In 2011, he said: "If you gave me the choice between picking the next 10 presidents or ensuring that energy is environmentally friendly and a quarter as costly, I'd pick the energy thing." + +In 2015, he wrote about the challenge of transitioning the world's energy system from one based primarily on fossil fuels to one based on sustainable energy sources. Global energy transitions have historically taken decades. He wrote, "I believe we can make this transition faster, both because the pace of innovation is accelerating, and because we have never had such an urgent reason to move from one source of energy to another." This rapid transition, according to Gates, would depend on increased government funding for basic research and financially risky private-sector investment, to enable innovation in diverse areas such as nuclear energy, grid energy storage to facilitate greater use of solar and wind energy, and solar fuels. + +Gates spearheaded two initiatives that he announced at the 2015 United Nations Climate Change Conference in Paris. One was Mission Innovation, in which 20 national governments pledged to double their spending on research and development for carbon-free energy in over five years' time. Another initiative was Breakthrough Energy, a group of investors who agreed to fund high-risk startups in clean energy technologies. Gates, who had already invested $1 billion of his own money in innovative energy startups, committed a further $1 billion to Breakthrough Energy. In December 2020, he called for the U.S. federal government to create institutes for clean energy research, analogous to the National Institutes of Health. Gates has also urged rich nations to shift to 100% synthetic beef industries to reduce greenhouse gas emissions from food production. + +Gates has been criticised for holding a large stake in Signature Aviation, a company that services emissions-intensive private jets. In 2019, he began to divest from fossil fuels. He does not expect divestment itself to have much practical impact, but says that if his efforts to provide alternatives were to fail, he would not want to personally benefit from an increase in fossil fuel stock prices. After he published his book How to Avoid a Climate Disaster, parts of the climate activist community criticized Gate's approach as technological solutionism. In 2022, educational streamer Wondrium produced the series "Solving for Zero: The Search for Climate Innovation" inspired by the book. + +In June 2021, Gates's company TerraPower and Warren Buffett's PacifiCorp announced the first sodium nuclear reactor in Wyoming. Wyoming Governor Mike Gordon hailed the project as a step toward carbon-negative nuclear power. Wyoming Senator John Barrasso also said that it could boost the state's once-active uranium mining industry. + +Gates spent many efforts to make pass the Inflation Reduction Act of 2022 because of his importance to climate. He tried to convince Joe Manchin to support a climate bill from the year 2019 and especially in the months before the adoption of the bill. The bill should cut the global greenhouse gas emissions in a level similar to "eliminating the annual planet-warming pollution of France and Germany combined" and may help to limit the warming of the planet to 1.5 degrees – the target of the Paris Agreement. He thanked both Joe Manchin and Chuck Schumer for their efforts in a guest essay in The New York Times, where he said "Inflation Reduction Act of 2022 may be the single most important piece of climate legislation in American history" given its potential to spur development of new technologies. Gates gave further insights on climate change in his commencement address at Northern Arizona University on May 6, 2023, where he was bestowed an honorary doctorate. + +Political positions + +Regulation of the software industry + +In 1998, Gates rejected the need for regulation of the software industry in testimony before the United States Senate. During the Federal Trade Commission's (FTC) investigation of Microsoft in the 1990s, Gates was reportedly upset at Commissioner Dennis Yao for "float[ing] a line of hypothetical questions suggesting possible curbs on Microsoft's growing monopoly power". According to one source: + +Donald Trump Facebook ban +On February 18, 2021, after Facebook and Twitter had banned Donald Trump from their platforms as a result of the 2020 United States presidential election which led to the January 6 United States Capitol attack, Gates said a permanent ban of Trump "would be a shame" and would be an "extreme measure". He warned that it would cause "polarization" if users with different political views divide up among various social networks, and said: "I don't think banning somebody who actually did get a fair number of votes (in the presidential election) – well less than a majority – forever would be that good." + +Patents for COVID-19 vaccines + +In April 2021, during the COVID-19 pandemic, Gates was criticized for suggesting that pharmaceutical companies should hold onto patents for COVID-19 vaccines. The criticism came due to the possibility of this preventing poorer nations from obtaining adequate vaccines. Tara Van Ho of the University of Essex stated, "Gates speaks as if all the lives being lost in India are inevitable but eventually the West will help when in reality the US & UK are holding their feet on the neck of developing states by refusing to break [intellectual property rights] protections. It's disgusting." + +Gates is opposed to the TRIPS waiver. Bloomberg News reported him as saying he argued that Oxford University should not give away the rights to its COVID-19 information, as it had announced, but instead sell it to a single industry partner, as it did. His views on the value of legal monopolies in medicine have been linked to his views on legal monopolies in software. + +Cryptocurrencies +Gates is critical of cryptocurrencies like Bitcoin. According to Gates, cryptocurrencies provide no "valuable output", contribute nothing to society, and pose a danger especially for smaller investors who could not survive the potentially high losses. Gates also does not own any cryptocurrencies himself. + +Philanthropy + +Bill and Melinda Gates Foundation + +Gates studied the work of Andrew Carnegie and John D. Rockefeller, and donated some of his Microsoft stock in 1994 to create the "William H. Gates Foundation". In 2000, Gates and his wife combined three family foundations and donated stock valued at $5 billion to create the Bill & Melinda Gates Foundation, which was identified by the Funds for NGOs company in 2013, as the world's largest charitable foundation, with assets reportedly valued at more than $34.6 billion. The foundation allows benefactors to access information that shows how its money is being spent, unlike other major charitable organizations such as the Wellcome Trust. Gates, through his foundation, also donated $20 million to the Carnegie Mellon University for a new building to be named Gates Center for Computer Science which opened in 2009. + +Gates has credited the generosity and extensive philanthropy of David Rockefeller as a major influence. He and his father met with Rockefeller several times, and their charity work is partly modeled on the Rockefeller family's philanthropic focus, whereby they are interested in tackling the global problems that are ignored by governments and other organizations. + +The foundation is organized into five program areas: Global Development Division, Global Health Division, United States Division, and Global Policy & Advocacy Division. Among others, it supports a wide range of public health projects, granting aid to fight transmissible diseases such AIDS, tuberculosis and malaria, as well as widespread vaccine programs to eradicate polio. It grants funds to learning institutes and libraries and supports scholarships at universities. The foundation established a water, sanitation and hygiene program to provide sustainable sanitation services in poor countries. Its agriculture division supports the International Rice Research Institute in developing Golden Rice, a genetically modified rice variant used to combat vitamin A deficiency. The foundation aims to provide women and girls in the developing world with information and support regarding contraception and, ultimately, universal access to consensual family planning. In 2007, the Los Angeles Times criticized the foundation for investing its assets in companies that have been accused of worsening poverty, pollution and pharmaceutical firms that do not sell to developing countries. Although the foundation announced a review of its investments to assess social responsibility, it was subsequently canceled and upheld its policy of investing for maximum return, while using voting rights to influence company practices. + +Gates delivered his thoughts in a fireside chat moderated by journalist and news anchor Shereen Bhan virtually at the Singapore FinTech Festival on December 8, 2020, on the topic, "Building Infrastructure for Resilience: What the COVID-19 Response Can Teach Us About How to Scale Financial Inclusion". + +Gates favors the normalization of COVID-19 masks. In a November 2020 interview, he said: "What are these, like, nudists? I mean, you know, we ask you to wear pants, and no American says, or very few Americans say, that that's, like, some terrible thing." + +Personal donations +Melinda Gates suggested that people should emulate the philanthropic efforts of the Salwen family, who sold their home and gave away half of its value, as detailed in their book, The Power of Half. Gates and his wife invited Joan Salwen to Seattle to speak about what the family had done, and on December 9, 2010, Bill and Melinda Gates and investor Warren Buffett each signed a commitment they called the "Giving Pledge", which is a commitment by all three to donate at least half of their wealth, over the course of time, to charity. + +Gates has also provided personal donations to educational institutions. In 1999, Gates donated $20 million to the Massachusetts Institute of Technology for the construction of a computer laboratory named the "William H. Gates Building" that was designed by architect Frank Gehry. While Microsoft had previously given financial support to the institution, this was the first personal donation received from Gates. + +The Maxwell Dworkin Laboratory of the Harvard John A. Paulson School of Engineering and Applied Sciences is named after the mothers of both Gates and Microsoft President Steven A. Ballmer, both of whom were students (Ballmer was a member of the school's graduating class of 1977, while Gates left his studies for Microsoft), and donated funds for the laboratory's construction. Gates also donated $6 million to the construction of the Gates Computer Science Building, completed in January 1996, on the campus of Stanford University. The building contains the Computer Science Department and the Computer Systems Laboratory (CSL) of Stanford's Engineering department. + +Since 2005, Gates and his foundation have taken an interest in solving global sanitation problems. For example, they announced the "Reinvent the Toilet Challenge", which has received considerable media interest. To raise awareness for the topic of sanitation and possible solutions, Gates drank water that was "produced from human feces" in 2014 – it was produced from a sewage sludge treatment process called the Omni Processor. In early 2015, he also appeared with Jimmy Fallon on The Tonight Show and challenged him to see if he could taste the difference between this reclaimed water or bottled water. + +In November 2017, Gates said he would give $50 million to the Dementia Discovery Fund, a venture capital fund that seeks treatment for Alzheimer's disease. He also pledged an additional $50 million to start-up ventures working in Alzheimer's research. Bill and Melinda Gates have said that they intend to leave their three children $10 million each as their inheritance. With only $30 million kept in the family, they are expected to give away about 99.96% of their wealth. On August 25, 2018, Gates distributed $600,000 through his foundation via UNICEF which is helping flood affected victims in Kerala, India. + +In June 2018, Gates offered free ebooks, to all new graduates of U.S. colleges and universities, and in 2021, offered free ebooks, to all college and university students around the world. The Bill And Melinda Gates Foundation partially funds OpenStax, which creates and provides free digital textbooks. + +In July 2022 he reiterated the commitment he had made by starting The Giving Pledge campaign by announcing on his Twitter channel he planned to give 'virtually all' his wealth to charity and eventually 'move off of the list of the world's richest people.' + +Charity sports events +On April 29, 2017, Gates partnered with Swiss tennis legend Roger Federer in playing in the Match for Africa 4, a noncompetitive tennis match at a sold-out Key Arena in Seattle. The event was in support of the Roger Federer Foundation's charity efforts in Africa. Federer and Gates played against John Isner, the top-ranked American player for much of this decade, and Mike McCready, the lead guitarist for Pearl Jam. The pair won the match 6 games to 4. Overall, they raised $2 million for children in Africa. The following year, Gates and Federer returned to play in the Match for Africa 5 on March 5, 2018, at San Jose's SAP Center. Their opponents were Jack Sock, one of the top American players and a grand slam winner in doubles, and Savannah Guthrie, a co-anchor for NBC's Today show. Gates and Federer recorded their second match victory together by a score of 6–3 and the event raised over $2.5 million. + +Books +Gates has so far authored four books: + The Road Ahead, co-authored with Microsoft executive Nathan Myhrvold and journalist Peter Rinearson, was published in November 1995. It summarized the implications of the personal computing revolution and described a future profoundly changed by the arrival of a global information superhighway. + Business @ the Speed of Thought, co-authored with Collins Hemingway, was published in 1999, and discusses how business and technology are integrated, and shows how digital infrastructures and information networks can help to get an edge on the competition. + How to Avoid a Climate Disaster, published in February 2021, presents what Gates learned in over a decade of studying climate change and investing in innovations to address climate problems. + How to Prevent the Next Pandemic, published in April 2022, details the COVID-19 pandemic and proposes a "Global Epidemic Response and Mobilization" (GERM) team with annual funding of $1 billion, under the auspices of the WHO. + +Personal life +Gates is an avid reader, and the ceiling of his large home library is engraved with a quotation from The Great Gatsby. He also enjoys bridge, tennis and golf. His days are planned for him on a minute-by-minute basis, similarly to the U.S. president's schedule. Despite his wealth and extensive business travel, Gates flew coach (economy class) in commercial aircraft until 1997, when he bought a private jet. + +Gates purchased the Codex Leicester, a collection of scientific writings by Leonardo da Vinci, for US$30.8 million at an auction in 1994. In 1998, he reportedly paid $30 million for the original 1885 maritime painting Lost on the Grand Banks, at the time a record price for an American painting. In 2016, he revealed that he was color-blind. On May 10, 2022, Gates said that he tested positive for COVID-19 and was experiencing mild symptoms. Gates has received three doses of the COVID-19 vaccine. + +Marriage and divorce + +Gates married Melinda French on the Hawaiian Island of Lanai on January 1, 1994. They met in 1987 after Melinda began working at Microsoft. At the time of their marriage, Gates was given permission by Melinda to spend limited time with his ex-girlfriend, businesswoman Ann Winblad. Bill and Melinda have three children: Jennifer, Rory and Phoebe. The family's residence is an earth-sheltered mansion in the side of a hill overlooking Lake Washington in Medina, Washington. In 2009, property taxes on the mansion were reported to be US$1.063 million, on a total assessed value of US$147.5 million. The estate has a swimming pool with an underwater music system, as well as a gym and a dining room. On May 3, 2021, the Gateses announced they had decided to divorce after 27 years of marriage and 34 years as a couple. They said they would keep working together on charitable efforts. The Wall Street Journal reported that Melinda had been meeting with divorce attorneys since 2019, citing interviews that suggested Bill's ties with Jeffrey Epstein was at least one of her concerns. The divorce was finalized on August 2, 2021. + +Public image + +Gates's public image has changed over the years. At first he was perceived as a brilliant but ruthless "robber baron", a "nerd-turned-tycoon". Starting in 2000 with the foundation of the Bill and Melinda Gates Foundation, and particularly after he stepped down as head of Microsoft, he turned his attention to philanthropy, spending more than $50 billion on causes like health, poverty, and education. His image morphed from "tyrannical technocrat to saintly savior" to a "huggable billionaire techno-philanthropist", celebrated on magazine covers and sought after for his opinions on major issues like global health and climate change. Still another shift in public opinion came in 2021 with the announcement that he and Melinda were divorcing. Coverage of that proceeding brought out information about romantic pursuits of women who worked for him, a long-term extra-marital affair, and a friendship with convicted sex offender Jeffrey Epstein. This information and his response to the COVID-19 pandemic resulted in some deterioration of his public image, going from "a lovable nerd who was out to save the world" to "a tech supervillain who wants to protect profits over public health." + +Investigative journalist Tim Schwab has accused Gates of using his contributions to the media to shape their coverage of him in order to protect his public image. In September 2022, Politico published an expose' critical of NGO leadership at the helm of the world-wide COVID-19 pandemic response, written in cooperation with the German newspaper Welt. Criticisms included the interconnectivity of the non-profits with Gates, as well as his personal lack of formal credentials in medicine. + +Gates and the projects of his foundation have been the subject of many conspiracy theories that proliferate on Facebook and elsewhere. He has been implausibly accused of attempting to depopulate the world, distributing harmful or unethical vaccines, and implanting people with privacy-violating microchips. These largely unfounded theories reached a new level of influence during the COVID-19 pandemic when, according to New York Times journalist Rory Smith, the uncertainties of pandemic life drove people to seek explanations from the Internet. When asked about the theories, Gates has remarked that some people are tempted by the "simple explanation" that an evil person rather than biological factors are to blame, and that he does not know for what purpose anyone believes he would want to track them with microchips. + +Religious views +In an interview with Rolling Stone, Gates said in regard to his faith: "The moral systems of religion, I think, are super important. We've raised our kids in a religious way; they've gone to the Catholic church that Melinda goes to and I participate in. I've been very lucky, and therefore I owe it to try and reduce the inequity in the world. And that's kind of a religious belief. I mean, it's at least a moral belief." In the same 2014 interview he also said: "I agree with people like Richard Dawkins that mankind felt the need for creation myths. Before we really began to understand disease and the weather and things like that, we sought false explanations for them. Now science has filled in some of the realm – not all – that religion used to fill. But the mystery and the beauty of the world is overwhelmingly amazing, and there's no scientific explanation of how it came about. To say that it was generated by random numbers, that does seem, you know, sort of an uncharitable view [laughs]. I think it makes sense to believe in God, but exactly what decision in your life you make differently because of it, I don't know." + +Wealth +In 1999, his wealth briefly surpassed US$100 billion making him the first person ever to achieve the feat. Since 2000, the nominal value of his Microsoft holdings declined due to the fall in Microsoft's stock price after the dot-com bubble burst and the multi-billion dollar donations he had made to his charitable foundations. In May 2006, Gates remarked that he wished that he were not the richest man in the world because he disliked the attention that it brought. In March 2010, Gates was the second wealthiest person after Carlos Slim, but regained the top position in 2013, according to the Bloomberg Billionaires Index. Slim retook the position again in June 2014 (but then lost the top position back to Gates). Between 2009 and 2014, his wealth doubled from US$40 billion to US$82 billion. In October 2017, Gates was surpassed by Amazon founder Jeff Bezos as the richest person in the world. On November 15, 2019, he once again became the richest person in the world after a 48% increase in Microsoft shares, surpassing Bezos. Gates told the BBC, "I've paid more tax than any individual ever, and gladly so ... I've paid over $6 billion in taxes." He is a proponent of higher taxes, particularly for the rich. + +By 2017, Gates had held the top spot on the list of The World's Billionaires in 18 out of the previous 23 years. Gates has several investments outside Microsoft, which in 2006 paid him a salary of US$616,667 and US$350,000 bonus totalling US$966,667. In 1989, he founded Corbis, a digital imaging company. In 2004, he became a board member of Berkshire Hathaway, the investment company headed by long-time friend Warren Buffett. + +In 1987, Gates was listed as a billionaire in Forbes magazine's first ever America's richest issue and was the world's youngest self-made billionaire with a net worth of $1.25 billion. Since 1987, Gates has been included in the Forbes The World's Billionaires list and was the wealthiest person from 1995 to 1996, 1998 to 2007, 2009, and held the spot until 2018 before being overtaken by Jeff Bezos. Gates was number one on the Forbes 400 list of wealthiest Americans from 1993 through to 2007, 2009, and 2014 through 2017. + +Controversies + +Antitrust litigation + +During his tenure as CEO of Microsoft, Gates approved of many decisions that led to antitrust litigation over Microsoft's business practices. In the 1998 United States v. Microsoft case, Gates gave deposition testimony that several journalists characterized as evasive. He argued with examiner David Boies over the contextual meaning of words such as "compete", "concerned", and "we". Later in the year, when portions of the videotaped deposition were played back in court, the judge was seen laughing and shaking his head. BusinessWeek reported: + +Gates later said that he had simply resisted attempts by Boies to mischaracterize his words and actions. "Did I fence with Boies? ... I plead guilty ... rudeness to Boies in the first degree." Despite Gates's denials, the judge ruled that Microsoft had committed monopolization, tying and blocking competition, each in violation of the Sherman Antitrust Act. + +Treatment of colleagues and employees +Gates had primary responsibility for Microsoft's product strategy from the company's founding in 1975 until 2006. He gained a reputation for being distant from others; an industry executive complained in 1981 that "Gates is notorious for not being reachable by phone and for not returning phone calls." An Atari executive recalled that he showed Gates a game and defeated him 35 of 37 times. When they met again a month later, Gates "won or tied every game. He had studied the game until he solved it. That is a competitor". + +In the early 1980s, while business partner Paul Allen was undergoing treatments for cancer, Gates — according to Allen — conspired to reduce the latter's share in Microsoft by issuing himself stock options. In his autobiography, Allen would later recall that Gates was "scheming to rip me off. It was mercenary opportunism plain and simple". Gates says he remembers the episode differently. Allen would also recall that Gates was prone to shouting episodes. + +Gates has often been accused of bullying Microsoft employees. He met regularly with Microsoft's senior managers and program managers, and the managers described him as being verbally combative, berating them for perceived holes in their business strategies or proposals that placed the company's long-term interests at risk. Gates saw competition in personal terms; when Borland's Turbo Pascal performed better than Microsoft's own tools, he yelled at programming director Greg Whitten "for half an hour" because, Gates believed, Borland's Philippe Kahn had surpassed Gates. Gates interrupted presentations with such comments as "that's the stupidest thing I've ever heard" and "why don't you just give up your options and join the Peace Corps?" The target of his outburst would then have to defend the proposal in detail until Gates was fully convinced. Not all harsh language was criticism; a manager recalled that "You're full of shit. That's the stupidest fucking thing I've ever heard" meant that Gates was amazed. "In the lore of Microsoft, if Bill says that to you, you're made". When subordinates appeared to be procrastinating, he was known to remark sarcastically, "I'll do it over the weekend". + +Relationship with Jeffrey Epstein +A 2019 New York Times article reported that Gates's relationship with financier Jeffrey Epstein started in 2011, just a few years after Epstein was convicted for procuring a child for prostitution, and continued for some years, including a visit to Epstein's house with his wife in the fall of 2013, despite her declared discomfort. Gates said in 2011 about Epstein: "His lifestyle is very different and kind of intriguing although it would not work for me". + +The depth of the friendship between Gates and Epstein is unclear though Gates generally commented that "I met him. I didn't have any business relationship or friendship with him". However, Gates visited Epstein "many times, despite [Epstein's] past". It was reported that Epstein and Gates "discussed the Gates Foundation and philanthropy". However, in an interview in 2019 Gates completely denied any connection between Epstein and the Gates Foundation or his philanthropy generally. In August 2021, Gates said the reason he had meetings with Epstein was because Gates hoped Epstein could provide money for philanthropic work, though nothing came of the idea. Gates added, "It was a huge mistake to spend time with him, to give him the credibility of being there." + +It has also been reported that Epstein and Gates met with Nobel Committee chair Thorbjørn Jagland at his residence in Strasbourg, France in March 2013 to discuss the Nobel Prize. Also in attendance were representatives of the International Peace Institute which has received millions in grants from the Gates Foundation, including a $2.5 million "community engagement" grant in October 2013. In 2023, it was reported that Epstein threatened to expose an alleged affair Gates had with a Russian bridge player. + +Recognition + + Time magazine named Gates as one of the 100 most influential people of the 20th century in 1999, as well as one of the 100 most influential people in 2004, 2005, and 2006 respectively. + Time also collectively named Gates, his wife Melinda and U2's lead singer Bono as the 2005 Persons of the Year for their humanitarian efforts.

It may also be known as the , or (literally "fat buttocks" in Dutch). Alternative names for this breed include Belgian Blue-White; Belgian White and Blue Pied; Belgian White Blue; Blue; and Blue Belgian. The Belgian Blue's extremely lean, hyper-sculpted, ultra-muscular physique is termed "double-muscling". The double-muscling phenotype is a heritable condition resulting in an increased number of muscle fibres (hyperplasia), instead of the (normal) enlargement of individual muscle fibres (hypertrophy). + +This particular trait is shared with another breed of cattle known as Piedmontese. Both of these breeds have an increased ability to convert feed into lean muscle, which causes these particular breeds' meat to have a reduced fat content and reduced tenderness. The Belgian Blue is named after its typically blue-grey mottled hair colour; however, its actual colour can vary from white to black. + +History +The breed originated in central and upper Belgium in the 19th century, from crossing local breeds with a Shorthorn breed of cattle from the United Kingdom. Charolais cattle possibly were cross-bred, as well. Belgian Blue cattle were first used as a dairy and beef breed. The modern beef breed was developed in the 1950s by Professor Hanset, working at an artificial insemination centre in Liège Province. The breed's characteristic gene mutation was maintained through linebreeding to the point where the condition was a fixed property in the Belgian Blue breed. In 1978, Belgian Blue cattle were introduced to the United States by Nick Tutt, a farmer from central Canada who emigrated to West Texas and showed the cattle to universities in the region. + +The Belgian Blue has been exported to many parts of the world; it is reported to DAD-IS by twenty-four countries, in Africa, the Americas, Europe and Oceania. Of these, ten report population data; in 2022 the worldwide population was estimated to be . + +Characteristics + +The Belgian Blue has a natural mutation in the myostatin gene which codes for the protein, myostatin ("myo" meaning muscle and "statin" meaning stop). Myostatin is a protein that inhibits muscle development. This mutation also interferes with fat deposition, resulting in very lean meat. The truncated myostatin gene is unable to function in its normal capacity, resulting in accelerated lean muscle growth. Muscle growth is due primarily to physiological changes in the animal's muscle cells (fibres) from hypertrophy to a hyperplasia mode of growth. This particular type of growth is seen early in the fetus of a pregnant dam, which results in a calf that is born with two times the number of muscle fibres at birth than a calf with no myostatin gene mutation. In addition, a newborn double-muscled calf's birth weight is significantly greater than that of a normal calf. + +Belgian Blue cattle have improved feed conversion ratio (FCR) due to lower feed intake compared to weight gain due to an altered composition of body weight gain which includes increased protein and decreased fat deposition. The Belgian Blue's bone structure is the same as normal cattle, albeit holding a greater amount of muscle, which causes them to have a greater meat to bone ratio. These cattle have a muscle yield around 20% more on average than cattle without the genetic myostatin mutation. Because of this breed's increased muscle yield, a diet containing higher protein is required to compensate for the altered mode of weight gain. During finishing, this breed requires high-energy (concentrated) feeds, and will not yield the same results if put on a high-fibre diet. + +Breed problems + +Double-muscled cows routinely experience dystocia – difficulty in parturition – even when bred to normal beef bulls or dairy bulls, because of a narrower birth canal; the birth weight and width of the calf also may be higher than in animals without the double-muscling gene. Calves are commonly born by Caesarean section; cows may be able to survive five or six deliveries of this type. + +In bulls, testicular weight and semen quantity and quality are lower than in other cattle, perhaps because of the greater amount of connective tissue in the testicles. however this is less of an issue when compared to the dam's difficulties in calving. + +Economic efficiency + +The economics of breeding and raising Belgian Blue cattle are inconclusive because of complications experienced during parturition and metabolic demand for more concentrated feeds. The breed's increased need to have Caesarean sections when calving means increased cost and added work, and can become a welfare issue. However, the carcass value of double-muscled animals may be enhanced due to increased dressing yield, lean carcass content, and upgrading of some cuts leading to a higher proportion of higher valued cuts. The slower rate of fat deposition causes slaughtering to be delayed in most cases, which means an increase in maintenance costs in those animals. Belgian Blue cattle require more skilled management and do not thrive in harsh environments. For these reasons and others, the breed's overall production efficiency in an economic sense is still unclear. + +References + +Cattle breeds originating in Belgium +Boron is a chemical element with the symbol B and atomic number 5. In its crystalline form it is a brittle, dark, lustrous metalloid; in its amorphous form it is a brown powder. As the lightest element of the boron group it has three valence electrons for forming covalent bonds, resulting in many compounds such as boric acid, the mineral sodium borate, and the ultra-hard crystals of boron carbide and boron nitride. + +Boron is synthesized entirely by cosmic ray spallation and supernovae and not by stellar nucleosynthesis, so it is a low-abundance element in the Solar System and in the Earth's crust. It constitutes about 0.001 percent by weight of Earth's crust. It is concentrated on Earth by the water-solubility of its more common naturally occurring compounds, the borate minerals. These are mined industrially as evaporites, such as borax and kernite. The largest known deposits are in Turkey, the largest producer of boron minerals. + +Elemental boron is a metalloid that is found in small amounts in meteoroids but chemically uncombined boron is not otherwise found naturally on Earth. Industrially, the very pure element is produced with difficulty because of contamination by carbon or other elements that resist removal. Several allotropes exist: amorphous boron is a brown powder; crystalline boron is silvery to black, extremely hard (about 9.5 on the Mohs scale), and a poor electrical conductor at room temperature. The primary use of the element itself is as boron filaments with applications similar to carbon fibers in some high-strength materials. + +Boron is primarily used in chemical compounds. About half of all production consumed globally is an additive in fiberglass for insulation and structural materials. The next leading use is in polymers and ceramics in high-strength, lightweight structural and heat-resistant materials. Borosilicate glass is desired for its greater strength and thermal shock resistance than ordinary soda lime glass. As sodium perborate, it is used as a bleach. A small amount is used as a dopant in semiconductors, and reagent intermediates in the synthesis of organic fine chemicals. A few boron-containing organic pharmaceuticals are used or are in study. Natural boron is composed of two stable isotopes, one of which (boron-10) has a number of uses as a neutron-capturing agent. + +The intersection of boron with biology is very small. Consensus on it as essential for mammalian life is lacking. Borates have low toxicity in mammals (similar to table salt) but are more toxic to arthropods and are occasionally used as insecticides. Boron-containing organic antibiotics are known. Although only traces are required, it is an essential plant nutrient. + +History +The word boron was coined from borax, the mineral from which it was isolated, by analogy with carbon, which boron resembles chemically. + +Borax in its mineral form (then known as tincal) first saw use as a glaze, beginning in China circa 300 AD. Some crude borax traveled westward, and was apparently mentioned by the alchemist Jabir ibn Hayyan around 700 AD. Marco Polo brought some glazes back to Italy in the 13th century. Georgius Agricola, in around 1600, reported the use of borax as a flux in metallurgy. In 1777, boric acid was recognized in the hot springs (soffioni) near Florence, Italy, at which point it became known as sal sedativum, with ostensible medical benefits. The mineral was named sassolite, after Sasso Pisano in Italy. Sasso was the main source of European borax from 1827 to 1872, when American sources replaced it. Boron compounds were relatively rarely used until the late 1800s when Francis Marion Smith's Pacific Coast Borax Company first popularized and produced them in volume at low cost. + +Boron was not recognized as an element until it was isolated by Sir Humphry Davy and by Joseph Louis Gay-Lussac and Louis Jacques Thénard. In 1808 Davy observed that electric current sent through a solution of borates produced a brown precipitate on one of the electrodes. In his subsequent experiments, he used potassium to reduce boric acid instead of electrolysis. He produced enough boron to confirm a new element and named it boracium. Gay-Lussac and Thénard used iron to reduce boric acid at high temperatures. By oxidizing boron with air, they showed that boric acid is its oxidation product. Jöns Jacob Berzelius identified it as an element in 1824. Pure boron was arguably first produced by the American chemist Ezekiel Weintraub in 1909. + +Preparation of elemental boron in the laboratory +The earliest routes to elemental boron involved the reduction of boric oxide with metals such as magnesium or aluminium. However, the product is almost always contaminated with borides of those metals. Pure boron can be prepared by reducing volatile boron halides with hydrogen at high temperatures. Ultrapure boron for use in the semiconductor industry is produced by the decomposition of diborane at high temperatures and then further purified by the zone melting or Czochralski processes. + +The production of boron compounds does not involve the formation of elemental boron, but exploits the convenient availability of borates. + +Characteristics + +Allotropes + +Boron is similar to carbon in its capability to form stable covalently bonded molecular networks. Even nominally disordered (amorphous) boron contains regular boron icosahedra which are bonded randomly to each other without long-range order. Crystalline boron is a very hard, black material with a melting point of above 2000 °C. It forms four major allotropes: α-rhombohedral and β-rhombohedral (α-R and β-R), γ-orthorhombic (γ) and β-tetragonal (β-T). All four phases are stable at ambient conditions, and β-rhombohedral is the most common and stable. An α-tetragonal phase also exists (α-T), but is very difficult to produce without significant contamination. Most of the phases are based on B12 icosahedra, but the γ phase can be described as a rocksalt-type arrangement of the icosahedra and B2 atomic pairs. It can be produced by compressing other boron phases to 12–20 GPa and heating to 1500–1800 °C; it remains stable after releasing the temperature and pressure. The β-T phase is produced at similar pressures, but higher temperatures of 1800–2200 °C. The α-T and β-T phases might coexist at ambient conditions, with the β-T phase being the more stable. Compressing boron above 160 GPa produces a boron phase with an as yet unknown structure, and this phase is a superconductor at temperatures below 6–12 K. Borospherene (fullerene-like B40 molecules) and borophene (proposed graphene-like structure) were described in 2014. + +Chemistry of the element + +Elemental boron is rare and poorly studied because the pure material is extremely difficult to prepare. Most studies of "boron" involve samples that contain small amounts of carbon. The chemical behavior of boron resembles that of silicon more than aluminium. Crystalline boron is chemically inert and resistant to attack by boiling hydrofluoric or hydrochloric acid. When finely divided, it is attacked slowly by hot concentrated hydrogen peroxide, hot concentrated nitric acid, hot sulfuric acid or hot mixture of sulfuric and chromic acids. + +The rate of oxidation of boron depends on the crystallinity, particle size, purity and temperature. Boron does not react with air at room temperature, but at higher temperatures it burns to form boron trioxide: +4 B + 3 O2 → 2 B2O3 + +Boron undergoes halogenation to give trihalides; for example, +2 B + 3 Br2 → 2 BBr3 +The trichloride in practice is usually made from the oxide. + +Atomic structure +Boron is the lightest element having an electron in a p-orbital in its ground state. Unlike most other p-elements, it rarely obeys the octet rule and usually places only six electrons (in three molecular orbitals) onto its valence shell. Boron is the prototype for the boron group (the IUPAC group 13), although the other members of this group are metals and more typical p-elements (only aluminium to some extent shares boron's aversion to the octet rule). + +Boron also has much lower electronegativity than subsequent period 2 elements. For the latter, lithium salts are common e.g. lithium fluoride, lithium hydroxide, lithium amide, and methyllithium, but lithium boryllides are extraordinarily rare. Strong bases do not deprotonate a borohydride R2BH to the boryl anion R2B−, instead forming the octet-complete adduct R2HB-base. + +Chemical compounds + +In the most familiar compounds, boron has the formal oxidation state III. These include oxides, sulfides, nitrides, and halides. + +The trihalides adopt a planar trigonal structure. These compounds are Lewis acids in that they readily form adducts with electron-pair donors, which are called Lewis bases. For example, fluoride (F−) and boron trifluoride (BF3) combined to give the tetrafluoroborate anion, BF4−. Boron trifluoride is used in the petrochemical industry as a catalyst. The halides react with water to form boric acid. + +It is found in nature on Earth almost entirely as various oxides of B(III), often associated with other elements. More than one hundred borate minerals contain boron in oxidation state +3. These minerals resemble silicates in some respect, although it is often found not only in a tetrahedral coordination with oxygen, but also in a trigonal planar configuration. Unlike silicates, boron minerals never contain it with coordination number greater than four. A typical motif is exemplified by the tetraborate anions of the common mineral borax, shown at left. The formal negative charge of the tetrahedral borate center is balanced by metal cations in the minerals, such as the sodium (Na+) in borax. The tourmaline group of borate-silicates is also a very important boron-bearing mineral group, and a number of borosilicates are also known to exist naturally. + +Boranes + +Boranes are chemical compounds of boron and hydrogen, with the generic formula of BxHy. These compounds do not occur in nature. Many of the boranes readily oxidise on contact with air, some violently. The parent member BH3 is called borane, but it is known only in the gaseous state, and dimerises to form diborane, B2H6. The larger boranes all consist of boron clusters that are polyhedral, some of which exist as isomers. For example, isomers of B20H26 are based on the fusion of two 10-atom clusters. + +The most important boranes are diborane B2H6 and two of its pyrolysis products, pentaborane B5H9 and decaborane B10H14. A large number of anionic boron hydrides are known, e.g. [B12H12]2−. + +The formal oxidation number in boranes is positive, and is based on the assumption that hydrogen is counted as −1 as in active metal hydrides. The mean oxidation number for the borons is then simply the ratio of hydrogen to boron in the molecule. For example, in diborane B2H6, the boron oxidation state is +3, but in decaborane B10H14, it is 7/5 or +1.4. In these compounds the oxidation state of boron is often not a whole number. + +Boron nitrides + +The boron nitrides are notable for the variety of structures that they adopt. They exhibit structures analogous to various allotropes of carbon, including graphite, diamond, and nanotubes. In the diamond-like structure, called cubic boron nitride (tradename Borazon), boron atoms exist in the tetrahedral structure of carbon atoms in diamond, but one in every four B-N bonds can be viewed as a coordinate covalent bond, wherein two electrons are donated by the nitrogen atom which acts as the Lewis base to a bond to the Lewis acidic boron(III) centre. Cubic boron nitride, among other applications, is used as an abrasive, as it has a hardness comparable with diamond (the two substances are able to produce scratches on each other). In the BN compound analogue of graphite, hexagonal boron nitride (h-BN), the positively charged boron and negatively charged nitrogen atoms in each plane lie adjacent to the oppositely charged atom in the next plane. Consequently, graphite and h-BN have very different properties, although both are lubricants, as these planes slip past each other easily. However, h-BN is a relatively poor electrical and thermal conductor in the planar directions. + +Organoboron chemistry + +A large number of organoboron compounds are known and many are useful in organic synthesis. Many are produced from hydroboration, which employs diborane, B2H6, a simple borane chemical, or carboboration. Organoboron(III) compounds are usually tetrahedral or trigonal planar, for example, tetraphenylborate, [B(C6H5)4]− vs. triphenylborane, B(C6H5)3. However, multiple boron atoms reacting with each other have a tendency to form novel dodecahedral (12-sided) and icosahedral (20-sided) structures composed completely of boron atoms, or with varying numbers of carbon heteroatoms. + +Organoboron chemicals have been employed in uses as diverse as boron carbide (see below), a complex very hard ceramic composed of boron-carbon cluster anions and cations, to carboranes, carbon-boron cluster chemistry compounds that can be halogenated to form reactive structures including carborane acid, a superacid. As one example, carboranes form useful molecular moieties that add considerable amounts of boron to other biochemicals in order to synthesize boron-containing compounds for boron neutron capture therapy for cancer. + +Compounds of B(I) and B(II) +As anticipated by its hydride clusters, boron forms a variety of stable compounds with formal oxidation state less than three. B2F4 and B4Cl4 are well characterized. + +Binary metal-boron compounds, the metal borides, contain boron in negative oxidation states. Illustrative is magnesium diboride (MgB2). Each boron atom has a formal −1 charge and magnesium is assigned a formal charge of +2. In this material, the boron centers are trigonal planar with an extra double bond for each boron, forming sheets akin to the carbon in graphite. However, unlike hexagonal boron nitride, which lacks electrons in the plane of the covalent atoms, the delocalized electrons in magnesium diboride allow it to conduct electricity similar to isoelectronic graphite. In 2001, this material was found to be a high-temperature superconductor. It is a superconductor under active development. A project at CERN to make MgB2 cables has resulted in superconducting test cables able to carry 20,000 amperes for extremely high current distribution applications, such as the contemplated high luminosity version of the Large Hadron Collider. + +Certain other metal borides find specialized applications as hard materials for cutting tools. Often the boron in borides has fractional oxidation states, such as −1/3 in calcium hexaboride (CaB6). + +From the structural perspective, the most distinctive chemical compounds of boron are the hydrides. Included in this series are the cluster compounds dodecaborate (), decaborane (B10H14), and the carboranes such as C2B10H12. Characteristically such compounds contain boron with coordination numbers greater than four. + +Isotopes + +Boron has two naturally occurring and stable isotopes, 11B (80.1%) and 10B (19.9%). The mass difference results in a wide range of δ11B values, which are defined as a fractional difference between the 11B and 10B and traditionally expressed in parts per thousand, in natural waters ranging from −16 to +59. There are 13 known isotopes of boron; the shortest-lived isotope is 7B which decays through proton emission and alpha decay with a half-life of 3.5×10−22 s. Isotopic fractionation of boron is controlled by the exchange reactions of the boron species B(OH)3 and [B(OH)4]−. Boron isotopes are also fractionated during mineral crystallization, during H2O phase changes in hydrothermal systems, and during hydrothermal alteration of rock. The latter effect results in preferential removal of the [10B(OH)4]− ion onto clays. It results in solutions enriched in 11B(OH)3 and therefore may be responsible for the large 11B enrichment in seawater relative to both oceanic crust and continental crust; this difference may act as an isotopic signature. + +The exotic 17B exhibits a nuclear halo, i.e. its radius is appreciably larger than that predicted by the liquid drop model. + +The 10B isotope is useful for capturing thermal neutrons (see neutron cross section#Typical cross sections). The nuclear industry enriches natural boron to nearly pure 10B. The less-valuable by-product, depleted boron, is nearly pure 11B. + +Commercial isotope enrichment +Because of its high neutron cross-section, boron-10 is often used to control fission in nuclear reactors as a neutron-capturing substance. Several industrial-scale enrichment processes have been developed; however, only the fractionated vacuum distillation of the dimethyl ether adduct of boron trifluoride (DME-BF3) and column chromatography of borates are being used. + +Enriched boron (boron-10) + +Enriched boron or 10B is used in both radiation shielding and is the primary nuclide used in neutron capture therapy of cancer. In the latter ("boron neutron capture therapy" or BNCT), a compound containing 10B is incorporated into a pharmaceutical which is selectively taken up by a malignant tumor and tissues near it. The patient is then treated with a beam of low energy neutrons at a relatively low neutron radiation dose. The neutrons, however, trigger energetic and short-range secondary alpha particle and lithium-7 heavy ion radiation that are products of the boron-neutron nuclear reaction, and this ion radiation additionally bombards the tumor, especially from inside the tumor cells. + +In nuclear reactors, 10B is used for reactivity control and in emergency shutdown systems. It can serve either function in the form of borosilicate control rods or as boric acid. In pressurized water reactors, 10B boric acid is added to the reactor coolant when the plant is shut down for refueling. It is then slowly filtered out over many months as fissile material is used up and the fuel becomes less reactive. + +In future crewed interplanetary spacecraft, 10B has a theoretical role as structural material (as boron fibers or BN nanotube material) which would also serve a special role in the radiation shield. One of the difficulties in dealing with cosmic rays, which are mostly high energy protons, is that some secondary radiation from interaction of cosmic rays and spacecraft materials is high energy spallation neutrons. Such neutrons can be moderated by materials high in light elements, such as polyethylene, but the moderated neutrons continue to be a radiation hazard unless actively absorbed in the shielding. Among light elements that absorb thermal neutrons, 6Li and 10B appear as potential spacecraft structural materials which serve both for mechanical reinforcement and radiation protection. + +Depleted boron (boron-11) + +Radiation-hardened semiconductors +Cosmic radiation will produce secondary neutrons if it hits spacecraft structures. Those neutrons will be captured in 10B, if it is present in the spacecraft's semiconductors, producing a gamma ray, an alpha particle, and a lithium ion. Those resultant decay products may then irradiate nearby semiconductor "chip" structures, causing data loss (bit flipping, or single event upset). In radiation-hardened semiconductor designs, one countermeasure is to use depleted boron, which is greatly enriched in 11B and contains almost no 10B. This is useful because 11B is largely immune to radiation damage. Depleted boron is a byproduct of the nuclear industry (see above). + +Proton-boron fusion + +11B is also a candidate as a fuel for aneutronic fusion. When struck by a proton with energy of about 500 keV, it produces three alpha particles and 8.7 MeV of energy. Most other fusion reactions involving hydrogen and helium produce penetrating neutron radiation, which weakens reactor structures and induces long-term radioactivity, thereby endangering operating personnel. The alpha particles from 11B fusion can be turned directly into electric power, and all radiation stops as soon as the reactor is turned off. + +NMR spectroscopy +Both 10B and 11B possess nuclear spin. The nuclear spin of 10B is 3 and that of 11B is . These isotopes are, therefore, of use in nuclear magnetic resonance spectroscopy; and spectrometers specially adapted to detecting the boron-11 nuclei are available commercially. The 10B and 11B nuclei also cause splitting in the resonances of attached nuclei. + +Occurrence + +Boron is rare in the Universe and solar system due to trace formation in the Big Bang and in stars. It is formed in minor amounts in cosmic ray spallation nucleosynthesis and may be found uncombined in cosmic dust and meteoroid materials. + +In the high oxygen environment of Earth, boron is always found fully oxidized to borate. Boron does not appear on Earth in elemental form. Extremely small traces of elemental boron were detected in Lunar regolith. + +Although boron is a relatively rare element in the Earth's crust, representing only 0.001% of the crust mass, it can be highly concentrated by the action of water, in which many borates are soluble. +It is found naturally combined in compounds such as borax and boric acid (sometimes found in volcanic spring waters). About a hundred borate minerals are known. + +On 5 September 2017, scientists reported that the Curiosity rover detected boron, an essential ingredient for life on Earth, on the planet Mars. Such a finding, along with previous discoveries that water may have been present on ancient Mars, further supports the possible early habitability of Gale Crater on Mars. + +Production +Economically important sources of boron are the minerals colemanite, rasorite (kernite), ulexite and tincal. Together these constitute 90% of mined boron-containing ore. The largest global borax deposits known, many still untapped, are in Central and Western Turkey, including the provinces of Eskişehir, Kütahya and Balıkesir. Global proven boron mineral mining reserves exceed one billion metric tonnes, against a yearly production of about four million tonnes. + +Turkey and the United States are the largest producers of boron products. Turkey produces about half of the global yearly demand, through Eti Mine Works () a Turkish state-owned mining and chemicals company focusing on boron products. It holds a government monopoly on the mining of borate minerals in Turkey, which possesses 72% of the world's known deposits. In 2012, it held a 47% share of production of global borate minerals, ahead of its main competitor, Rio Tinto Group. + +Almost a quarter (23%) of global boron production comes from the single Rio Tinto Borax Mine (also known as the U.S. Borax Boron Mine) near Boron, California. + +Market trend +The average cost of crystalline elemental boron is US$5/g. Elemental boron is chiefly used in making boron fibers, where it is deposited by chemical vapor deposition on a tungsten core (see below). Boron fibers are used in lightweight composite applications, such as high strength tapes. This use is a very small fraction of total boron use. Boron is introduced into semiconductors as boron compounds, by ion implantation. + +Estimated global consumption of boron (almost entirely as boron compounds) was about 4 million tonnes of B2O3 in 2012. As compounds such as borax and kernite its cost was US$377/tonne in 2019. Boron mining and refining capacities are considered to be adequate to meet expected levels of growth through the next decade. + +The form in which boron is consumed has changed in recent years. The use of ores like colemanite has declined following concerns over arsenic content. Consumers have moved toward the use of refined borates and boric acid that have a lower pollutant content. + +Increasing demand for boric acid has led a number of producers to invest in additional capacity. Turkey's state-owned Eti Mine Works opened a new boric acid plant with the production capacity of 100,000 tonnes per year at Emet in 2003. Rio Tinto Group increased the capacity of its boron plant from 260,000 tonnes per year in 2003 to 310,000 tonnes per year by May 2005, with plans to grow this to 366,000 tonnes per year in 2006. Chinese boron producers have been unable to meet rapidly growing demand for high quality borates. This has led to imports of sodium tetraborate (borax) growing by a hundredfold between 2000 and 2005 and boric acid imports increasing by 28% per year over the same period. + +The rise in global demand has been driven by high growth rates in glass fiber, fiberglass and borosilicate glassware production. A rapid increase in the manufacture of reinforcement-grade boron-containing fiberglass in Asia, has offset the development of boron-free reinforcement-grade fiberglass in Europe and the US. The recent rises in energy prices may lead to greater use of insulation-grade fiberglass, with consequent growth in the boron consumption. Roskill Consulting Group forecasts that world demand for boron will grow by 3.4% per year to reach 21 million tonnes by 2010. The highest growth in demand is expected to be in Asia where demand could rise by an average 5.7% per year. + +Applications + +Nearly all boron ore extracted from the Earth is destined for refinement into boric acid and sodium tetraborate pentahydrate. In the United States, 70% of the boron is used for the production of glass and ceramics. +The major global industrial-scale use of boron compounds (about 46% of end-use) is in production of glass fiber for boron-containing insulating and structural fiberglasses, especially in Asia. Boron is added to the glass as borax pentahydrate or boron oxide, to influence the strength or fluxing qualities of the glass fibers. Another 10% of global boron production is for borosilicate glass as used in high strength glassware. About 15% of global boron is used in boron ceramics, including super-hard materials discussed below. Agriculture consumes 11% of global boron production, and bleaches and detergents about 6%. + +Elemental boron fiber +Boron fibers (boron filaments) are high-strength, lightweight materials that are used chiefly for advanced aerospace structures as a component of composite materials, as well as limited production consumer and sporting goods such as golf clubs and fishing rods. The fibers can be produced by chemical vapor deposition of boron on a tungsten filament. + +Boron fibers and sub-millimeter sized crystalline boron springs are produced by laser-assisted chemical vapor deposition. Translation of the focused laser beam allows production of even complex helical structures. Such structures show good mechanical properties (elastic modulus 450 GPa, fracture strain 3.7%, fracture stress 17 GPa) and can be applied as reinforcement of ceramics or in micromechanical systems. + +Boronated fiberglass + +Fiberglass is a fiber reinforced polymer made of plastic reinforced by glass fibers, commonly woven into a mat. The glass fibers used in the material are made of various types of glass depending upon the fiberglass use. These glasses all contain silica or silicate, with varying amounts of oxides of calcium, magnesium, and sometimes boron. The boron is present as borosilicate, borax, or boron oxide, and is added to increase the strength of the glass, or as a fluxing agent to decrease the melting temperature of silica, which is too high to be easily worked in its pure form to make glass fibers. + +The highly boronated glasses used in fiberglass are E-glass (named for "Electrical" use, but now the most common fiberglass for general use). E-glass is alumino-borosilicate glass with less than 1% w/w alkali oxides, mainly used for glass-reinforced plastics. Other common high-boron glasses include C-glass, an alkali-lime glass with high boron oxide content, used for glass staple fibers and insulation, and D-glass, a borosilicate glass, named for its low dielectric constant. + +Not all fiberglasses contain boron, but on a global scale, most of the fiberglass used does contain it. Because of the ubiquitous use of fiberglass in construction and insulation, boron-containing fiberglasses consume half the global production of boron, and are the single largest commercial boron market. + +Borosilicate glass + +Borosilicate glass, which is typically 12–15% B2O3, 80% SiO2, and 2% Al2O3, has a low coefficient of thermal expansion, giving it a good resistance to thermal shock. Schott AG's "Duran" and Owens-Corning's trademarked Pyrex are two major brand names for this glass, used both in laboratory glassware and in consumer cookware and bakeware, chiefly for this resistance. + +Boron carbide ceramic + +Several boron compounds are known for their extreme hardness and toughness. +Boron carbide is a ceramic material which is obtained by decomposing B2O3 with carbon in an electric furnace: +2 B2O3 + 7 C → B4C + 6 CO + +Boron carbide's structure is only approximately B4C, and it shows a clear depletion of carbon from this suggested stoichiometric ratio. This is due to its very complex structure. The substance can be seen with empirical formula B12C3 (i.e., with B12 dodecahedra being a motif), but with less carbon, as the suggested C3 units are replaced with C-B-C chains, and some smaller (B6) octahedra are present as well (see the boron carbide article for structural analysis). The repeating polymer plus semi-crystalline structure of boron carbide gives it great structural strength per weight. It is used in tank armor, bulletproof vests, and numerous other structural applications. + +Boron carbide's ability to absorb neutrons without forming long-lived radionuclides (especially when doped with extra boron-10) makes the material attractive as an absorbent for neutron radiation arising in nuclear power plants. Nuclear applications of boron carbide include shielding, control rods and shut-down pellets. Within control rods, boron carbide is often powdered, to increase its surface area. + +High-hardness and abrasive compounds + +Boron carbide and cubic boron nitride powders are widely used as abrasives. Boron nitride is a material isoelectronic to carbon. Similar to carbon, it has both hexagonal (soft graphite-like h-BN) and cubic (hard, diamond-like c-BN) forms. h-BN is used as a high temperature component and lubricant. c-BN, also known under commercial name borazon, is a superior abrasive. Its hardness is only slightly smaller than, but its chemical stability is superior, to that of diamond. Heterodiamond (also called BCN) is another diamond-like boron compound. + +Metallurgy + +Boron is added to boron steels at the level of a few parts per million to increase hardenability. Higher percentages are added to steels used in the nuclear industry due to boron's neutron absorption ability. + +Boron can also increase the surface hardness of steels and alloys through boriding. Additionally metal borides are used for coating tools through chemical vapor deposition or physical vapor deposition. Implantation of boron ions into metals and alloys, through ion implantation or ion beam deposition, results in a spectacular increase in surface resistance and microhardness. Laser alloying has also been successfully used for the same purpose. These borides are an alternative to diamond coated tools, and their (treated) surfaces have similar properties to those of the bulk boride. + +For example, rhenium diboride can be produced at ambient pressures, but is rather expensive because of rhenium. The hardness of ReB2 exhibits considerable anisotropy because of its hexagonal layered structure. Its value is comparable to that of tungsten carbide, silicon carbide, titanium diboride or zirconium diboride. +Similarly, AlMgB14 + TiB2 composites possess high hardness and wear resistance and are used in either bulk form or as coatings for components exposed to high temperatures and wear loads. + +Detergent formulations and bleaching agents +Borax is used in various household laundry and cleaning products, including the "20 Mule Team Borax" laundry booster and "Boraxo" powdered hand soap. It is also present in some tooth bleaching formulas. + +Sodium perborate serves as a source of active oxygen in many detergents, laundry detergents, cleaning products, and laundry bleaches. However, despite its name, "Borateem" laundry bleach no longer contains any boron compounds, using sodium percarbonate instead as a bleaching agent. + +Insecticides +Boric acid is used as an insecticide, notably against ants, fleas, and cockroaches. + +Semiconductors +Boron is a useful dopant for such semiconductors as silicon, germanium, and silicon carbide. Having one fewer valence electron than the host atom, it donates a hole resulting in p-type conductivity. Traditional method of introducing boron into semiconductors is via its atomic diffusion at high temperatures. This process uses either solid (B2O3), liquid (BBr3), or gaseous boron sources (B2H6 or BF3). However, after the 1970s, it was mostly replaced by ion implantation, which relies mostly on BF3 as a boron source. Boron trichloride gas is also an important chemical in semiconductor industry, however, not for doping but rather for plasma etching of metals and their oxides. Triethylborane is also injected into vapor deposition reactors as a boron source. Examples are the plasma deposition of boron-containing hard carbon films, silicon nitride–boron nitride films, and for doping of diamond film with boron. + +Magnets +Boron is a component of neodymium magnets (Nd2Fe14B), which are among the strongest type of permanent magnet. These magnets are found in a variety of electromechanical and electronic devices, such as magnetic resonance imaging (MRI) medical imaging systems, in compact and relatively small motors and actuators. As examples, computer HDDs (hard disk drives), CD (compact disk) and DVD (digital versatile disk) players rely on neodymium magnet motors to deliver intense rotary power in a remarkably compact package. In mobile phones 'Neo' magnets provide the magnetic field which allows tiny speakers to deliver appreciable audio power. + +Shielding and neutron absorber in nuclear reactors +Boron shielding is used as a control for nuclear reactors, taking advantage of its high cross-section for neutron capture. + +In pressurized water reactors a variable concentration of boronic acid in the cooling water is used as a neutron poison to compensate the variable reactivity of the fuel. When new rods are inserted the concentration of boronic acid is maximal, and is reduced during the lifetime. + +Other nonmedical uses + + Because of its distinctive green flame, amorphous boron is used in pyrotechnic flares. + In the 1950s, there were several studies of the use of boranes as energy-increasing "Zip fuel" additives for jet fuel. + Starch and casein-based adhesives contain sodium tetraborate decahydrate (Na2B4O7·10 H2O) + Some anti-corrosion systems contain borax. + Sodium borates are used as a flux for soldering silver and gold and with ammonium chloride for welding ferrous metals. They are also fire retarding additives to plastics and rubber articles. + Boric acid (also known as orthoboric acid) H3BO3 is used in the production of textile fiberglass and flat panel displays and in many PVAc- and PVOH-based adhesives. + Triethylborane is a substance which ignites the JP-7 fuel of the Pratt & Whitney J58 turbojet/ramjet engines powering the Lockheed SR-71 Blackbird. It was also used to ignite the F-1 Engines on the Saturn V Rocket utilized by NASA's Apollo and Skylab programs from 1967 until 1973. Today SpaceX uses it to ignite the engines on their Falcon 9 rocket. Triethylborane is suitable for this because of its pyrophoric properties, especially the fact that it burns with a very high temperature. Triethylborane is an industrial initiator in radical reactions, where it is effective even at low temperatures. + Borates are used as environmentally benign wood preservatives. + +Pharmaceutical and biological applications +Boron plays a role in pharmaceutical and biological applications as it is found in various bacteria-produced antibiotics, such as boromycins, aplasmomycins, borophycins, and tartrolons. These antibiotics have shown inhibitory effects on certain bacteria, fungi, and protozoa growth. Boron is also being studied for its potential medicinal applications, including its incorporation into biologically active molecules for therapies like boron neutron capture therapy for brain tumors. Some boron-containing biomolecules may act as signaling molecules interacting with cell surfaces, suggesting a role in cellular communication. + +Boric acid has antiseptic, antifungal, and antiviral properties and, for these reasons, is applied as a water clarifier in swimming pool water treatment. Mild solutions of boric acid have been used as eye antiseptics. + +Bortezomib (marketed as Velcade and Cytomib). Boron appears as an active element in the organic pharmaceutical bortezomib, a new class of drug called the proteasome inhibitor, for treating myeloma and one form of lymphoma (it is currently in experimental trials against other types of lymphoma). The boron atom in bortezomib binds the catalytic site of the 26S proteasome with high affinity and specificity. + A number of potential boronated pharmaceuticals using boron-10, have been prepared for use in boron neutron capture therapy (BNCT). + Some boron compounds show promise in treating arthritis, though none have as yet been generally approved for the purpose. + +Tavaborole (marketed as Kerydin) is an Aminoacyl tRNA synthetase inhibitor which is used to treat toenail fungus. It gained FDA approval in July 2014. + +Dioxaborolane chemistry enables radioactive fluoride (18F) labeling of antibodies or red blood cells, which allows for positron emission tomography (PET) imaging of cancer and hemorrhages, respectively. A Human-Derived, Genetic, Positron-emitting and Fluorescent (HD-GPF) reporter system uses a human protein, PSMA and non-immunogenic, and a small molecule that is positron-emitting (boron bound 18F) and fluorescence for dual modality PET and fluorescent imaging of genome modified cells, e.g. cancer, CRISPR/Cas9, or CAR T-cells, in an entire mouse. The dual-modality small molecule targeting PSMA was tested in humans and found the location of primary and metastatic prostate cancer, fluorescence-guided removal of cancer, and detects single cancer cells in tissue margins. + +In neutron capture therapy (BNCT) for malignant brain tumors, boron is researched to be used for selectively targeting and destroying tumor cells. The goal is to deliver higher concentrations of the non-radioactive boron isotope (10B) to the tumor cells than to the surrounding normal tissues. When these 10B-containing cells are irradiated with low-energy thermal neutrons, they undergo nuclear capture reactions, releasing high linear energy transfer (LET) particles such as α-particles and lithium-7 nuclei within a limited path length. These high-LET particles can destroy the adjacent tumor cells without causing significant harm to nearby normal cells. Boron acts as a selective agent due to its ability to absorb thermal neutrons and produce short-range physical effects primarily affecting the targeted tissue region. This binary approach allows for precise tumor cell killing while sparing healthy tissues. The effective delivery of boron involves administering boron compounds or carriers capable of accumulating selectively in tumor cells compared to surrounding tissue. BSH and BPA have been used clinically, but research continues to identify more optimal carriers. Accelerator-based neutron sources have also been developed recently as an alternative to reactor-based sources, leading to improved efficiency and enhanced clinical outcomes in BNCT. By employing the properties of boron isotopes and targeted irradiation techniques, BNCT offers a potential approach to treating malignant brain tumors by selectively killing cancer cells while minimizing the damage caused by traditional radiation therapies. + +BNCT has shown promising results in clinical trials for various other malignancies, including glioblastoma, head and neck cancer, cutaneous melanoma, hepatocellular carcinoma, lung cancer, and extramammary Paget's disease. The treatment involves a nuclear reaction between nonradioactive boron-10 isotope and low-energy thermal or high-energy epithermal neutrons to generate α particles and lithium nuclei that selectively destroy DNA in tumor cells. The primary challenge lies in developing efficient boron agents with higher content and specific targeting properties tailored for BNCT. Integration of tumor-targeting strategies with BNCT could potentially establish it as a practical personalized treatment option for different types of cancers. Ongoing research explores new boron compounds, optimization strategies, theranostic agents, and radiobiological advances to overcome limitations and cost-effectively improve patient outcomes. + +Research areas +Magnesium diboride is an important superconducting material with the transition temperature of 39 K. MgB2 wires are produced with the powder-in-tube process and applied in superconducting magnets. + +Amorphous boron is used as a melting point depressant in nickel-chromium braze alloys. + +Hexagonal boron nitride forms atomically thin layers, which have been used to enhance the electron mobility in graphene devices. It also forms nanotubular structures (BNNTs), which have high strength, high chemical stability, and high thermal conductivity, among its list of desirable properties. + +Boron has multiple applications in nuclear fusion research. It is commonly used for conditioning the walls in fusion reactors by depositing boron coatings on plasma-facing components and walls to reduce the release of hydrogen and impurities from the surfaces. It is also being used for the dissipation of energy in the fusion plasma boundary to suppress excessive energy bursts and heat fluxes to the walls. + +Biological role + +Boron is an essential plant nutrient, required primarily for maintaining the integrity of cell walls. However, high soil concentrations of greater than 1.0 ppm lead to marginal and tip necrosis in leaves as well as poor overall growth performance. Levels as low as 0.8 ppm produce these same symptoms in plants that are particularly sensitive to boron in the soil. Nearly all plants, even those somewhat tolerant of soil boron, will show at least some symptoms of boron toxicity when soil boron content is greater than 1.8 ppm. When this content exceeds 2.0 ppm, few plants will perform well and some may not survive. + +It is thought that boron plays several essential roles in animals, including humans, but the exact physiological role is poorly understood. A small human trial published in 1987 reported on postmenopausal women first made boron deficient and then repleted with 3 mg/day. Boron supplementation markedly reduced urinary calcium excretion and elevated the serum concentrations of 17 beta-estradiol and testosterone. + +Boron is not classified as an essential human nutrient because research has not established a clear biological function for boron. Still, studies suggest that boron may exert beneficial effects on reproduction and development, calcium metabolism, bone formation, brain function, insulin and energy substrate metabolism, immunity, and steroid hormone (including estrogen) and vitamin D function, among other functions. The U.S. Food and Nutrition Board (FNB) found the existing data insufficient to derive a Recommended Dietary Allowance (RDA), Adequate Intake (AI), or Estimated Average Requirement (EAR) for boron. The U.S. Food and Drug Administration (FDA) has not established a Daily Value for boron for food and dietary supplement labeling purposes. While low boron status can be detrimental to health, probably increasing the risk of osteoporosis, poor immune function, and cognitive decline; high boron levels are associated with cell damage and toxicity. The exact mechanism by which boron exerts its physiological effects is not fully understood, but may involve interactions with adenosine monophosphate (ADP) and S-adenosyl methionine (SAM-e), two compounds involved in important cellular functions. Furthermore, boron appears to inhibit cyclic ADP-ribose, thereby affecting the release of calcium ions from the endoplasmic reticulum and affecting various biological processes. Some studies suggest that boron may reduce levels of inflammatory biomarkers. + +In humans, boron is usually consumed with food that contains boron, such as fruits, leafy vegetables, and nuts. Foods that are particularly rich in boron include avocados, dried fruits such as raisins, peanuts, pecans, prune juice, grape juice, wine and chocolate powder. According to 2-day food records from the respondents to the Third National Health and Nutrition Examination Survey (NHANES III), adult dietary intake was recorded at 0.9 to 1.4 mg/day. + +In 2013, a hypothesis suggested it was possible that boron and molybdenum catalyzed the production of RNA on Mars with life being transported to Earth via a meteorite around 3 billion years ago. + +There exist several known boron-containing natural antibiotics. The first one found was boromycin, isolated from streptomyces in the 1960s. Others are tartrolons, a group of antibiotics discovered in the 1990s from culture broth of the myxobacterium Sorangium cellulosum. + +Congenital endothelial dystrophy type 2, a rare form of corneal dystrophy, is linked to mutations in SLC4A11 gene that encodes a transporter reportedly regulating the intracellular concentration of boron. + +Analytical quantification +For determination of boron content in food or materials, the colorimetric curcumin method is used. Boron is converted to boric acid or borates and on reaction with curcumin in acidic solution, a red colored boron-chelate complex, rosocyanine, is formed. + +Health issues and toxicity + +Elemental boron, boron oxide, boric acid, borates, and many organoboron compounds are relatively nontoxic to humans and animals (with toxicity similar to that of table salt). The LD50 (dose at which there is 50% mortality) for animals is about 6 g per kg of body weight. Substances with LD50 above 2 g/kg are considered nontoxic. An intake of 4 g/day of boric acid was reported without incident, but more than this is considered toxic in more than a few doses. Intakes of more than 0.5 grams per day for 50 days cause minor digestive and other problems suggestive of toxicity. Dietary supplementation of boron may be helpful for bone growth, wound healing, and antioxidant activity, and insufficient amount of boron in diet may result in boron deficiency. + +Single medical doses of 20 g of boric acid for neutron capture therapy have been used without undue toxicity. + +Boric acid is more toxic to insects than to mammals, and is routinely used as an insecticide. + +The boranes (boron hydrogen compounds) and similar gaseous compounds are quite poisonous. As usual, boron is not an element that is intrinsically poisonous, but the toxicity of these compounds depends on structure (for another example of this phenomenon, see phosphine). The boranes are also highly flammable and require special care when handling, some combinations of boranes and other compounds are highly explosive. Sodium borohydride presents a fire hazard owing to its reducing nature and the liberation of hydrogen on contact with acid. Boron halides are corrosive. + +Boron is necessary for plant growth, but an excess of boron is toxic to plants, and occurs particularly in acidic soil. It presents as a yellowing from the tip inwards of the oldest leaves and black spots in barley leaves, but it can be confused with other stresses such as magnesium deficiency in other plants. + +See also + + Allotropes of boron + Boron deficiency + Boron oxide + Boron nitride + Boron neutron capture therapy + Boronic acid + Hydroboration-oxidation reaction + Suzuki coupling + +References + +External links + Boron at The Periodic Table of Videos (University of Nottingham) + J.

It is a volatile red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour. Its properties are intermediate between those of chlorine and iodine. Isolated independently by two chemists, Carl Jacob Löwig (in 1825) and Antoine Jérôme Balard (in 1826), its name was derived from the Ancient Greek (bromos) meaning "stench", referring to its sharp and pungent smell. + +Elemental bromine is very reactive and thus does not occur as a free element in nature. Instead, it can be isolated from colourless soluble crystalline mineral halide salts analogous to table salt, a property it shares with the other halogens. While it is rather rare in the Earth's crust, the high solubility of the bromide ion (Br) has caused its accumulation in the oceans. Commercially the element is easily extracted from brine evaporation ponds, mostly in the United States and Israel. The mass of bromine in the oceans is about one three-hundredth that of chlorine. + +At standard conditions for temperature and pressure it is a liquid; the only other element that is liquid under these conditions is mercury. At high temperatures, organobromine compounds readily dissociate to yield free bromine atoms, a process that stops free radical chemical chain reactions. This effect makes organobromine compounds useful as fire retardants, and more than half the bromine produced worldwide each year is put to this purpose. The same property causes ultraviolet sunlight to dissociate volatile organobromine compounds in the atmosphere to yield free bromine atoms, causing ozone depletion. As a result, many organobromine compounds—such as the pesticide methyl bromide—are no longer used. Bromine compounds are still used in well drilling fluids, in photographic film, and as an intermediate in the manufacture of organic chemicals. + +Large amounts of bromide salts are toxic from the action of soluble bromide ions, causing bromism. However, bromine is beneficial for human eosinophils, and is an essential trace element for collagen development in all animals. Hundreds of known organobromine compounds are generated by terrestrial and marine plants and animals, and some serve important biological roles. As a pharmaceutical, the simple bromide ion (Br) has inhibitory effects on the central nervous system, and bromide salts were once a major medical sedative, before replacement by shorter-acting drugs. They retain niche uses as antiepileptics. + +History + +Bromine was discovered independently by two chemists, Carl Jacob Löwig and Antoine Balard, in 1825 and 1826, respectively. + +Löwig isolated bromine from a mineral water spring from his hometown Bad Kreuznach in 1825. Löwig used a solution of the mineral salt saturated with chlorine and extracted the bromine with diethyl ether. After evaporation of the ether, a brown liquid remained. With this liquid as a sample of his work he applied for a position in the laboratory of Leopold Gmelin in Heidelberg. The publication of the results was delayed and Balard published his results first. + +Balard found bromine chemicals in the ash of seaweed from the salt marshes of Montpellier. The seaweed was used to produce iodine, but also contained bromine. Balard distilled the bromine from a solution of seaweed ash saturated with chlorine. The properties of the resulting substance were intermediate between those of chlorine and iodine; thus he tried to prove that the substance was iodine monochloride (ICl), but after failing to do so he was sure that he had found a new element and named it muride, derived from the Latin word ("brine"). + +After the French chemists Louis Nicolas Vauquelin, Louis Jacques Thénard, and Joseph-Louis Gay-Lussac approved the experiments of the young pharmacist Balard, the results were presented at a lecture of the Académie des Sciences and published in Annales de Chimie et Physique. In his publication, Balard stated that he changed the name from muride to brôme on the proposal of M. Anglada. The name brôme (bromine) derives from the Greek (, "stench"). Other sources claim that the French chemist and physicist Joseph-Louis Gay-Lussac suggested the name brôme for the characteristic smell of the vapors. Bromine was not produced in large quantities until 1858, when the discovery of salt deposits in Stassfurt enabled its production as a by-product of potash. + +Apart from some minor medical applications, the first commercial use was the daguerreotype. In 1840, bromine was discovered to have some advantages over the previously used iodine vapor to create the light sensitive silver halide layer in daguerreotypy. + +Potassium bromide and sodium bromide were used as anticonvulsants and sedatives in the late 19th and early 20th centuries, but were gradually superseded by chloral hydrate and then by the barbiturates. In the early years of the First World War, bromine compounds such as xylyl bromide were used as poison gas. + +Properties +Bromine is the third halogen, being a nonmetal in group 17 of the periodic table. Its properties are thus similar to those of fluorine, chlorine, and iodine, and tend to be intermediate between those of the two neighbouring halogens, chlorine, and iodine. Bromine has the electron configuration [Ar]4s3d4p, with the seven electrons in the fourth and outermost shell acting as its valence electrons. Like all halogens, it is thus one electron short of a full octet, and is hence a strong oxidising agent, reacting with many elements in order to complete its outer shell. Corresponding to periodic trends, it is intermediate in electronegativity between chlorine and iodine (F: 3.98, Cl: 3.16, Br: 2.96, I: 2.66), and is less reactive than chlorine and more reactive than iodine. It is also a weaker oxidising agent than chlorine, but a stronger one than iodine. Conversely, the bromide ion is a weaker reducing agent than iodide, but a stronger one than chloride. These similarities led to chlorine, bromine, and iodine together being classified as one of the original triads of Johann Wolfgang Döbereiner, whose work foreshadowed the periodic law for chemical elements. It is intermediate in atomic radius between chlorine and iodine, and this leads to many of its atomic properties being similarly intermediate in value between chlorine and iodine, such as first ionisation energy, electron affinity, enthalpy of dissociation of the X molecule (X = Cl, Br, I), ionic radius, and X–X bond length. The volatility of bromine accentuates its very penetrating, choking, and unpleasant odour. + +All four stable halogens experience intermolecular van der Waals forces of attraction, and their strength increases together with the number of electrons among all homonuclear diatomic halogen molecules. Thus, the melting and boiling points of bromine are intermediate between those of chlorine and iodine. As a result of the increasing molecular weight of the halogens down the group, the density and heats of fusion and vaporisation of bromine are again intermediate between those of chlorine and iodine, although all their heats of vaporisation are fairly low (leading to high volatility) thanks to their diatomic molecular structure. The halogens darken in colour as the group is descended: fluorine is a very pale yellow gas, chlorine is greenish-yellow, and bromine is a reddish-brown volatile liquid that melts at −7.2 °C and boils at 58.8 °C. (Iodine is a shiny black solid.) This trend occurs because the wavelengths of visible light absorbed by the halogens increase down the group. Specifically, the colour of a halogen, such as bromine, results from the electron transition between the highest occupied antibonding π molecular orbital and the lowest vacant antibonding σ molecular orbital. The colour fades at low temperatures so that solid bromine at −195 °C is pale yellow. + +Like solid chlorine and iodine, solid bromine crystallises in the orthorhombic crystal system, in a layered arrangement of Br molecules. The Br–Br distance is 227 pm (close to the gaseous Br–Br distance of 228 pm) and the Br···Br distance between molecules is 331 pm within a layer and 399 pm between layers (compare the van der Waals radius of bromine, 195 pm). This structure means that bromine is a very poor conductor of electricity, with a conductivity of around 5 × 10 Ω cm just below the melting point, although this is higher than the essentially undetectable conductivity of chlorine. + +At a pressure of 55 GPa (roughly 540,000 times atmospheric pressure) bromine undergoes an insulator-to-metal transition. At 75 GPa it changes to a face-centered orthorhombic structure. At 100 GPa it changes to a body centered orthorhombic monatomic form. + +Isotopes + +Bromine has two stable isotopes, Br and Br. These are its only two natural isotopes, with Br making up 51% of natural bromine and Br making up the remaining 49%. Both have nuclear spin 3/2− and thus may be used for nuclear magnetic resonance, although Br is more favourable. The relatively 1:1 distribution of the two isotopes in nature is helpful in identification of bromine containing compounds using mass spectroscopy. Other bromine isotopes are all radioactive, with half-lives too short to occur in nature. Of these, the most important are Br (t = 17.7 min), Br (t = 4.421 h), and Br (t = 35.28 h), which may be produced from the neutron activation of natural bromine. The most stable bromine radioisotope is Br (t = 57.04 h). The primary decay mode of isotopes lighter than Br is electron capture to isotopes of selenium; that of isotopes heavier than Br is beta decay to isotopes of krypton; and Br may decay by either mode to stable Se or Kr. Br isotopes from Br-87 and heavier undergo beta decay with neutron emission and are of practical importance because they are fission products; Br-87 with half-life 55 s is notable as the longest lived delayed neutron emitter. + +Chemistry and compounds + +Bromine is intermediate in reactivity between chlorine and iodine, and is one of the most reactive elements. Bond energies to bromine tend to be lower than those to chlorine but higher than those to iodine, and bromine is a weaker oxidising agent than chlorine but a stronger one than iodine. This can be seen from the standard electrode potentials of the X/X couples (F, +2.866 V; Cl, +1.395 V; Br, +1.087 V; I, +0.615 V; At, approximately +0.3 V). Bromination often leads to higher oxidation states than iodination but lower or equal oxidation states to chlorination. Bromine tends to react with compounds including M–M, M–H, or M–C bonds to form M–Br bonds. + +Hydrogen bromide +The simplest compound of bromine is hydrogen bromide, HBr. It is mainly used in the production of inorganic bromides and alkyl bromides, and as a catalyst for many reactions in organic chemistry. Industrially, it is mainly produced by the reaction of hydrogen gas with bromine gas at 200–400 °C with a platinum catalyst. However, reduction of bromine with red phosphorus is a more practical way to produce hydrogen bromide in the laboratory: + 2 P + 6 HO + 3 Br → 6 HBr + 2 HPO + HPO + HO + Br → 2 HBr + HPO + +At room temperature, hydrogen bromide is a colourless gas, like all the hydrogen halides apart from hydrogen fluoride, since hydrogen cannot form strong hydrogen bonds to the large and only mildly electronegative bromine atom; however, weak hydrogen bonding is present in solid crystalline hydrogen bromide at low temperatures, similar to the hydrogen fluoride structure, before disorder begins to prevail as the temperature is raised. Aqueous hydrogen bromide is known as hydrobromic acid, which is a strong acid (pK = −9) because the hydrogen bonds to bromine are too weak to inhibit dissociation. The HBr/HO system also involves many hydrates HBr·nHO for n = 1, 2, 3, 4, and 6, which are essentially salts of bromine anions and hydronium cations. Hydrobromic acid forms an azeotrope with boiling point 124.3 °C at 47.63 g HBr per 100 g solution; thus hydrobromic acid cannot be concentrated beyond this point by distillation. + +Unlike hydrogen fluoride, anhydrous liquid hydrogen bromide is difficult to work with as a solvent, because its boiling point is low, it has a small liquid range, its dielectric constant is low and it does not dissociate appreciably into HBr and ions – the latter, in any case, are much less stable than the bifluoride ions () due to the very weak hydrogen bonding between hydrogen and bromine, though its salts with very large and weakly polarising cations such as Cs and (R = Me, Et, Bu) may still be isolated. Anhydrous hydrogen bromide is a poor solvent, only able to dissolve small molecular compounds such as nitrosyl chloride and phenol, or salts with very low lattice energies such as tetraalkylammonium halides. + +Other binary bromides + +Nearly all elements in the periodic table form binary bromides. The exceptions are decidedly in the minority and stem in each case from one of three causes: extreme inertness and reluctance to participate in chemical reactions (the noble gases, with the exception of xenon in the very unstable XeBr); extreme nuclear instability hampering chemical investigation before decay and transmutation (many of the heaviest elements beyond bismuth); and having an electronegativity higher than bromine's (oxygen, nitrogen, fluorine, and chlorine), so that the resultant binary compounds are formally not bromides but rather oxides, nitrides, fluorides, or chlorides of bromine. (Nonetheless, nitrogen tribromide is named as a bromide as it is analogous to the other nitrogen trihalides.) + +Bromination of metals with Br tends to yield lower oxidation states than chlorination with Cl when a variety of oxidation states is available. Bromides can be made by reaction of an element or its oxide, hydroxide, or carbonate with hydrobromic acid, and then dehydrated by mildly high temperatures combined with either low pressure or anhydrous hydrogen bromide gas. These methods work best when the bromide product is stable to hydrolysis; otherwise, the possibilities include high-temperature oxidative bromination of the element with bromine or hydrogen bromide, high-temperature bromination of a metal oxide or other halide by bromine, a volatile metal bromide, carbon tetrabromide, or an organic bromide. For example, niobium(V) oxide reacts with carbon tetrabromide at 370 °C to form niobium(V) bromide. Another method is halogen exchange in the presence of excess "halogenating reagent", for example: +FeCl + BBr (excess) → FeBr + BCl +When a lower bromide is wanted, either a higher halide may be reduced using hydrogen or a metal as a reducing agent, or thermal decomposition or disproportionation may be used, as follows: + 3 WBr + Al 3 WBr + AlBr + EuBr + H → EuBr + HBr + 2 TaBr TaBr + TaBr + +Most metal bromides with the metal in low oxidation states (+1 to +3) are ionic. Nonmetals tend to form covalent molecular bromides, as do metals in high oxidation states from +3 and above. Both ionic and covalent bromides are known for metals in oxidation state +3 (e.g. scandium bromide is mostly ionic, but aluminium bromide is not). Silver bromide is very insoluble in water and is thus often used as a qualitative test for bromine. + +Bromine halides +The halogens form many binary, diamagnetic interhalogen compounds with stoichiometries XY, XY, XY, and XY (where X is heavier than Y), and bromine is no exception. Bromine forms a monofluoride and monochloride, as well as a trifluoride and pentafluoride. Some cationic and anionic derivatives are also characterised, such as , , , , and . Apart from these, some pseudohalides are also known, such as cyanogen bromide (BrCN), bromine thiocyanate (BrSCN), and bromine azide (BrN). + +The pale-brown bromine monofluoride (BrF) is unstable at room temperature, disproportionating quickly and irreversibly into bromine, bromine trifluoride, and bromine pentafluoride. It thus cannot be obtained pure. It may be synthesised by the direct reaction of the elements, or by the comproportionation of bromine and bromine trifluoride at high temperatures. Bromine monochloride (BrCl), a red-brown gas, quite readily dissociates reversibly into bromine and chlorine at room temperature and thus also cannot be obtained pure, though it can be made by the reversible direct reaction of its elements in the gas phase or in carbon tetrachloride. Bromine monofluoride in ethanol readily leads to the monobromination of the aromatic compounds PhX (para-bromination occurs for X = Me, Bu, OMe, Br; meta-bromination occurs for the deactivating X = –COEt, –CHO, –NO); this is due to heterolytic fission of the Br–F bond, leading to rapid electrophilic bromination by Br. + +At room temperature, bromine trifluoride (BrF) is a straw-coloured liquid. It may be formed by directly fluorinating bromine at room temperature and is purified through distillation. It reacts violently with water and explodes on contact with flammable materials, but is a less powerful fluorinating reagent than chlorine trifluoride. It reacts vigorously with boron, carbon, silicon, arsenic, antimony, iodine, and sulfur to give fluorides, and will also convert most metals and many metal compounds to fluorides; as such, it is used to oxidise uranium to uranium hexafluoride in the nuclear power industry. Refractory oxides tend to be only partially fluorinated, but here the derivatives KBrF and BrFSbF remain reactive. Bromine trifluoride is a useful nonaqueous ionising solvent, since it readily dissociates to form and and thus conducts electricity. + +Bromine pentafluoride (BrF) was first synthesised in 1930. It is produced on a large scale by direct reaction of bromine with excess fluorine at temperatures higher than 150 °C, and on a small scale by the fluorination of potassium bromide at 25 °C. It also reacts violently with water and is a very strong fluorinating agent, although chlorine trifluoride is still stronger. + +Polybromine compounds +Although dibromine is a strong oxidising agent with a high first ionisation energy, very strong oxidisers such as peroxydisulfuryl fluoride (SOF) can oxidise it to form the cherry-red cation. A few other bromine cations are known, namely the brown and dark brown . The tribromide anion, , has also been characterised; it is analogous to triiodide. + +Bromine oxides and oxoacids + +Bromine oxides are not as well-characterised as chlorine oxides or iodine oxides, as they are all fairly unstable: it was once thought that they could not exist at all. Dibromine monoxide is a dark-brown solid which, while reasonably stable at −60 °C, decomposes at its melting point of −17.5 °C; it is useful in bromination reactions and may be made from the low-temperature decomposition of bromine dioxide in a vacuum. It oxidises iodine to iodine pentoxide and benzene to 1,4-benzoquinone; in alkaline solutions, it gives the hypobromite anion. + +So-called "bromine dioxide", a pale yellow crystalline solid, may be better formulated as bromine perbromate, BrOBrO. It is thermally unstable above −40 °C, violently decomposing to its elements at 0 °C. Dibromine trioxide, syn-BrOBrO, is also known; it is the anhydride of hypobromous acid and bromic acid. It is an orange crystalline solid which decomposes above −40 °C; if heated too rapidly, it explodes around 0 °C. A few other unstable radical oxides are also known, as are some poorly characterised oxides, such as dibromine pentoxide, tribromine octoxide, and bromine trioxide. + +The four oxoacids, hypobromous acid (HOBr), bromous acid (HOBrO), bromic acid (HOBrO), and perbromic acid (HOBrO), are better studied due to their greater stability, though they are only so in aqueous solution. When bromine dissolves in aqueous solution, the following reactions occur: +{| +|- +| Br + HO || HOBr + H + Br || K = 7.2 × 10 mol l +|- +| Br + 2 OH || OBr + HO + Br || K = 2 × 10 mol l +|} + +Hypobromous acid is unstable to disproportionation. The hypobromite ions thus formed disproportionate readily to give bromide and bromate: +{| +|- +| 3 BrO 2 Br + || K = 10 +|} + +Bromous acids and bromites are very unstable, although the strontium and barium bromites are known. More important are the bromates, which are prepared on a small scale by oxidation of bromide by aqueous hypochlorite, and are strong oxidising agents. Unlike chlorates, which very slowly disproportionate to chloride and perchlorate, the bromate anion is stable to disproportionation in both acidic and aqueous solutions. Bromic acid is a strong acid. Bromides and bromates may comproportionate to bromine as follows: + + 5 Br + 6 H → 3 Br + 3 HO + +There were many failed attempts to obtain perbromates and perbromic acid, leading to some rationalisations as to why they should not exist, until 1968 when the anion was first synthesised from the radioactive beta decay of unstable . Today, perbromates are produced by the oxidation of alkaline bromate solutions by fluorine gas. Excess bromate and fluoride are precipitated as silver bromate and calcium fluoride, and the perbromic acid solution may be purified. The perbromate ion is fairly inert at room temperature but is thermodynamically extremely oxidising, with extremely strong oxidising agents needed to produce it, such as fluorine or xenon difluoride. The Br–O bond in is fairly weak, which corresponds to the general reluctance of the 4p elements arsenic, selenium, and bromine to attain their group oxidation state, as they come after the scandide contraction characterised by the poor shielding afforded by the radial-nodeless 3d orbitals. + +Organobromine compounds + +Like the other carbon–halogen bonds, the C–Br bond is a common functional group that forms part of core organic chemistry. Formally, compounds with this functional group may be considered organic derivatives of the bromide anion. Due to the difference of electronegativity between bromine (2.96) and carbon (2.55), the carbon atom in a C–Br bond is electron-deficient and thus electrophilic. The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. For many applications, organobromides represent a compromise of reactivity and cost. + +Organobromides are typically produced by additive or substitutive bromination of other organic precursors. Bromine itself can be used, but due to its toxicity and volatility, safer brominating reagents are normally used, such as N-bromosuccinimide. The principal reactions for organobromides include dehydrobromination, Grignard reactions, reductive coupling, and nucleophilic substitution. + +Organobromides are the most common organohalides in nature, even though the concentration of bromide is only 0.3% of that for chloride in sea water, because of the easy oxidation of bromide to the equivalent of Br, a potent electrophile. The enzyme bromoperoxidase catalyzes this reaction. The oceans are estimated to release 1–2 million tons of bromoform and 56,000 tons of bromomethane annually. + +An old qualitative test for the presence of the alkene functional group is that alkenes turn brown aqueous bromine solutions colourless, forming a bromohydrin with some of the dibromoalkane also produced. The reaction passes through a short-lived strongly electrophilic bromonium intermediate. This is an example of a halogen addition reaction. + +Occurrence and production + +Bromine is significantly less abundant in the crust than fluorine or chlorine, comprising only 2.5 parts per million of the Earth's crustal rocks, and then only as bromide salts. It is the forty-sixth most abundant element in Earth's crust. It is significantly more abundant in the oceans, resulting from long-term leaching. There, it makes up 65 parts per million, corresponding to a ratio of about one bromine atom for every 660 chlorine atoms. Salt lakes and brine wells may have higher bromine concentrations: for example, the Dead Sea contains 0.4% bromide ions. It is from these sources that bromine extraction is mostly economically feasible. + +The main sources of bromine production are Israel and Jordan. The element is liberated by halogen exchange, using chlorine gas to oxidise Br to Br. This is then removed with a blast of steam or air, and is then condensed and purified. Today, bromine is transported in large-capacity metal drums or lead-lined tanks that can hold hundreds of kilograms or even tonnes of bromine. The bromine industry is about one-hundredth the size of the chlorine industry. Laboratory production is unnecessary because bromine is commercially available and has a long shelf life. + +Applications +A wide variety of organobromine compounds are used in industry. Some are prepared from bromine and others are prepared from hydrogen bromide, which is obtained by burning hydrogen in bromine. + +Flame retardants + +Brominated flame retardants represent a commodity of growing importance, and make up the largest commercial use of bromine. When the brominated material burns, the flame retardant produces hydrobromic acid which interferes in the radical chain reaction of the oxidation reaction of the fire. The mechanism is that the highly reactive hydrogen radicals, oxygen radicals, and hydroxy radicals react with hydrobromic acid to form less reactive bromine radicals (i.e., free bromine atoms). Bromine atoms may also react directly with other radicals to help terminate the free radical chain-reactions that characterise combustion. + +To make brominated polymers and plastics, bromine-containing compounds can be incorporated into the polymer during polymerisation. One method is to include a relatively small amount of brominated monomer during the polymerisation process. For example, vinyl bromide can be used in the production of polyethylene, polyvinyl chloride or polypropylene. Specific highly brominated molecules can also be added that participate in the polymerisation process For example, tetrabromobisphenol A can be added to polyesters or epoxy resins, where it becomes part of the polymer. Epoxies used in printed circuit boards are normally made from such flame retardant resins, indicated by the FR in the abbreviation of the products (FR-4 and FR-2). In some cases, the bromine-containing compound may be added after polymerisation. For example, decabromodiphenyl ether can be added to the final polymers. + +A number of gaseous or highly volatile brominated halomethane compounds are non-toxic and make superior fire suppressant agents by this same mechanism, and are particularly effective in enclosed spaces such as submarines, airplanes, and spacecraft. However, they are expensive and their production and use has been greatly curtailed due to their effect as ozone-depleting agents. They are no longer used in routine fire extinguishers, but retain niche uses in aerospace and military automatic fire suppression applications. They include bromochloromethane (Halon 1011, CHBrCl), bromochlorodifluoromethane (Halon 1211, CBrClF), and bromotrifluoromethane (Halon 1301, CBrF). + +Other uses + +Silver bromide is used, either alone or in combination with silver chloride and silver iodide, as the light sensitive constituent of photographic emulsions. + +Ethylene bromide was an additive in gasolines containing lead anti-engine knocking agents. It scavenges lead by forming volatile lead bromide, which is exhausted from the engine. This application accounted for 77% of the bromine use in 1966 in the US. This application has declined since the 1970s due to environmental regulations (see below). + +Brominated vegetable oil (BVO), a complex mixture of plant-derived triglycerides that have been reacted to contain atoms of the element bromine bonded to the molecules, is used primarily to help emulsify citrus-flavored soft drinks, preventing them from separating during distribution. + +Poisonous bromomethane was widely used as pesticide to fumigate soil and to fumigate housing, by the tenting method. Ethylene bromide was similarly used. These volatile organobromine compounds are all now regulated as ozone depletion agents. The Montreal Protocol on Substances that Deplete the Ozone Layer scheduled the phase out for the ozone depleting chemical by 2005, and organobromide pesticides are no longer used (in housing fumigation they have been replaced by such compounds as sulfuryl fluoride, which contain neither the chlorine or bromine organics which harm ozone). Before the Montreal protocol in 1991 (for example) an estimated 35,000 tonnes of the chemical were used to control nematodes, fungi, weeds and other soil-borne diseases. + +In pharmacology, inorganic bromide compounds, especially potassium bromide, were frequently used as general sedatives in the 19th and early 20th century. Bromides in the form of simple salts are still used as anticonvulsants in both veterinary and human medicine, although the latter use varies from country to country. For example, the U.S. Food and Drug Administration (FDA) does not approve bromide for the treatment of any disease, and it was removed from over-the-counter sedative products like Bromo-Seltzer, in 1975. Commercially available organobromine pharmaceuticals include the vasodilator nicergoline, the sedative brotizolam, the anticancer agent pipobroman, and the antiseptic merbromin. Otherwise, organobromine compounds are rarely pharmaceutically useful, in contrast to the situation for organofluorine compounds. Several drugs are produced as the bromide (or equivalents, hydrobromide) salts, but in such cases bromide serves as an innocuous counterion of no biological significance. + +Other uses of organobromine compounds include high-density drilling fluids, dyes (such as Tyrian purple and the indicator bromothymol blue), and pharmaceuticals. Bromine itself, as well as some of its compounds, are used in water treatment, and is the precursor of a variety of inorganic compounds with an enormous number of applications (e.g. silver bromide for photography). Zinc–bromine batteries are hybrid flow batteries used for stationary electrical power backup and storage; from household scale to industrial scale. + +Bromine is used in cooling towers (in place of chlorine) for controlling bacteria, algae, fungi, and zebra mussels. + +Because it has similar antiseptic qualities to chlorine, bromine can be used in the same manner as chlorine as a disinfectant or antimicrobial in applications such as swimming pools. However, bromine is usually not used outside for these applications due to it being relatively more expensive than chlorine and the absence of a stabilizer to protect it from the sun. For indoor pools, it can be a good option as it is effective at a wider pH range. It is also more stable in a heated pool or hot tub. + +Biological role and toxicity + +A 2014 study suggests that bromine (in the form of bromide ion) is a necessary cofactor in the biosynthesis of collagen IV, making the element essential to basement membrane architecture and tissue development in animals. Nevertheless, no clear deprivation symptoms or syndromes have been documented in mammals. In other biological functions, bromine may be non-essential but still beneficial when it takes the place of chlorine. For example, in the presence of hydrogen peroxide, HO, formed by the eosinophil, and either chloride or bromide ions, eosinophil peroxidase provides a potent mechanism by which eosinophils kill multicellular parasites (such as the nematode worms involved in filariasis) and some bacteria (such as tuberculosis bacteria). Eosinophil peroxidase is a haloperoxidase that preferentially uses bromide over chloride for this purpose, generating hypobromite (hypobromous acid), although the use of chloride is possible. + +α-Haloesters are generally thought of as highly reactive and consequently toxic intermediates in organic synthesis. Nevertheless, mammals, including humans, cats, and rats, appear to biosynthesize traces of an α-bromoester, 2-octyl 4-bromo-3-oxobutanoate, which is found in their cerebrospinal fluid and appears to play a yet unclarified role in inducing REM sleep. Neutrophil myeloperoxidase can use HO and Br to brominate deoxycytidine, which could result in DNA mutations. Marine organisms are the main source of organobromine compounds, and it is in these organisms that bromine is more firmly shown to be essential. More than 1600 such organobromine compounds were identified by 1999. The most abundant is methyl bromide (CHBr), of which an estimated 56,000 tonnes is produced by marine algae each year. The essential oil of the Hawaiian alga Asparagopsis taxiformis consists of 80% bromoform. Most of such organobromine compounds in the sea are made by the action of a unique algal enzyme, vanadium bromoperoxidase. + +The bromide anion is not very toxic: a normal daily intake is 2 to 8 milligrams. However, high levels of bromide chronically impair the membrane of neurons, which progressively impairs neuronal transmission, leading to toxicity, known as bromism. Bromide has an elimination half-life of 9 to 12 days, which can lead to excessive accumulation. Doses of 0.5 to 1 gram per day of bromide can lead to bromism. Historically, the therapeutic dose of bromide is about 3 to 5 grams of bromide, thus explaining why chronic toxicity (bromism) was once so common. While significant and sometimes serious disturbances occur to neurologic, psychiatric, dermatological, and gastrointestinal functions, death from bromism is rare. Bromism is caused by a neurotoxic effect on the brain which results in somnolence, psychosis, seizures and delirium. + +Elemental bromine is toxic and causes chemical burns on human flesh. Inhaling bromine gas results in similar irritation of the respiratory tract, causing coughing, choking, shortness of breath, and death if inhaled in large enough amounts. Chronic exposure may lead to frequent bronchial infections and a general deterioration of health. As a strong oxidising agent, bromine is incompatible with most organic and inorganic compounds. Caution is required when transporting bromine; it is commonly carried in steel tanks lined with lead, supported by strong metal frames. The Occupational Safety and Health Administration (OSHA) of the United States has set a permissible exposure limit (PEL) for bromine at a time-weighted average (TWA) of 0.1 ppm. The National Institute for Occupational Safety and Health (NIOSH) has set a recommended exposure limit (REL) of TWA 0.1 ppm and a short-term limit of 0.3 ppm. The exposure to bromine immediately dangerous to life and health (IDLH) is 3 ppm. Bromine is classified as an extremely hazardous substance in the United States as defined in Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act (42 U.S.C. 11002), and is subject to strict reporting requirements by facilities which produce, store, or use it in significant quantities. + +References + +General and cited references + + + +Chemical elements +Diatomic nonmetals +Gases with color +Halogens +Oxidizing agents +Reactive nonmetals +Barium is a chemical element with the symbol Ba and atomic number 56.

Barium compounds are added to fireworks to impart a green color. Barium sulfate is used as an insoluble additive to oil well drilling fluid. In a purer form it is used as X-ray radiocontrast agents for imaging the human gastrointestinal tract. Water-soluble barium compounds are poisonous and have been used as rodenticides. + +Characteristics + +Physical properties + +Barium is a soft, silvery-white metal, with a slight golden shade when ultrapure. The silvery-white color of barium metal rapidly vanishes upon oxidation in air yielding a dark gray layer containing the oxide. Barium has a medium specific weight and high electrical conductivity. Because barium is difficult to purify, many of its properties have not been accurately determined. + +At room temperature and pressure, barium metal adopts a body-centered cubic structure, with a barium–barium distance of 503 picometers, expanding with heating at a rate of approximately 1.8/°C. It is a very soft metal with a Mohs hardness of 1.25. Its melting temperature of is intermediate between those of the lighter strontium () and heavier radium (); however, its boiling point of exceeds that of strontium (). The density (3.62 g/cm3) is again intermediate between those of strontium (2.36 g/cm3) and radium (≈5 g/cm3). + +Chemical reactivity +Barium is chemically similar to magnesium, calcium, and strontium, but even more reactive. It is usually found in the +2 oxidation state. Most exceptions are in a few rare and unstable molecular species that are only characterised in the gas phase such as BaF, but in 2018 a barium(I) species was reported in a graphite intercalation compound. Reactions with chalcogens are highly exothermic (release energy); the reaction with oxygen or air occurs at room temperature. For this reason, metallic barium is often stored under oil or in an inert atmosphere. Reactions with other nonmetals, such as carbon, nitrogen, phosphorus, silicon, and hydrogen, are generally exothermic and proceed upon heating. Reactions with water and alcohols are very exothermic and release hydrogen gas: + Ba + 2 ROH → Ba(OR)2 + H2↑ (R is an alkyl group or a hydrogen atom) + +Barium reacts with ammonia to form complexes such as Ba(NH3)6. + +The metal is readily attacked by acids. Sulfuric acid is a notable exception because passivation stops the reaction by forming the insoluble barium sulfate on the surface. Barium combines with several other metals, including aluminium, zinc, lead, and tin, forming intermetallic phases and alloys. + +Compounds + +Barium salts are typically white when solid and colorless when dissolved. They are denser than the strontium or calcium analogs, except for the halides (see table; zinc is given for comparison). + +Barium hydroxide ("baryta") was known to alchemists, who produced it by heating barium carbonate. Unlike calcium hydroxide, it absorbs very little CO2 in aqueous solutions and is therefore insensitive to atmospheric fluctuations. This property is used in calibrating pH equipment. + +Volatile barium compounds burn with a green to pale green flame, which is an efficient test to detect a barium compound. The color results from spectral lines at 455.4, 493.4, 553.6, and 611.1 nm. + +Organobarium compounds are a growing field of knowledge: recently discovered are dialkylbariums and alkylhalobariums. + +Isotopes + +Barium found in the Earth's crust is a mixture of seven primordial nuclides, barium-130, 132, and 134 through 138. Barium-130 undergoes very slow radioactive decay to xenon-130 by double beta plus decay, with a half-life of (0.5–2.7)×1021 years (about 1011 times the age of the universe). Its abundance is ≈0.1% that of natural barium. Theoretically, barium-132 can similarly undergo double beta decay to xenon-132; this decay has not been detected. The radioactivity of these isotopes is so weak that they pose no danger to life. + +Of the stable isotopes, barium-138 composes 71.7% of all barium; other isotopes have decreasing abundance with decreasing mass number. + +In total, barium has 40 known isotopes, ranging in mass between 114 and 153. The most stable artificial radioisotope is barium-133 with a half-life of approximately 10.51 years. Five other isotopes have half-lives longer than a day. Barium also has 10 meta states, of which barium-133m1 is the most stable with a half-life of about 39 hours. + +History + +Alchemists in the early Middle Ages knew about some barium minerals. Smooth pebble-like stones of mineral baryte were found in volcanic rock near Bologna, Italy, and so were called "Bologna stones". Alchemists were attracted to them because after exposure to light they would glow for years. The phosphorescent properties of baryte heated with organics were described by V. Casciorolus in 1602. + +Carl Scheele determined that baryte contained a new element in 1772, but could not isolate barium, only barium oxide. Johan Gottlieb Gahn also isolated barium oxide two years later in similar studies. Oxidized barium was at first called "barote" by Guyton de Morveau, a name that was changed by Antoine Lavoisier to baryte (in French) or baryta (in Latin). Also in the 18th century, English mineralogist William Withering noted a heavy mineral in the lead mines of Cumberland, now known to be witherite. Barium was first isolated by electrolysis of molten barium salts in 1808 by Sir Humphry Davy in England. Davy, by analogy with calcium, named "barium" after baryta, with the "-ium" ending signifying a metallic element. Robert Bunsen and Augustus Matthiessen obtained pure barium by electrolysis of a molten mixture of barium chloride and ammonium chloride. + +The production of pure oxygen in the Brin process was a large-scale application of barium peroxide in the 1880s, before it was replaced by electrolysis and fractional distillation of liquefied air in the early 1900s. In this process barium oxide reacts at with air to form barium peroxide, which decomposes above by releasing oxygen: +2 BaO + O2 ⇌ 2 BaO2 + +Barium sulfate was first applied as a radiocontrast agent in X-ray imaging of the digestive system in 1908. + +Occurrence and production +The abundance of barium is 0.0425% in the Earth's crust and 13 μg/L in sea water. The primary commercial source of barium is baryte (also called barytes or heavy spar), a barium sulfate mineral. with deposits in many parts of the world. Another commercial source, far less important than baryte, is witherite, barium carbonate. The main deposits are located in Britain, Romania, and the former USSR. + +The baryte reserves are estimated between 0.7 and 2 billion tonnes. The maximum production, 8.3 million tonnes, was produced in 1981, but only 7–8% was used for barium metal or compounds. Baryte production has risen since the second half of the 1990s from 5.6 million tonnes in 1996 to 7.6 in 2005 and 7.8 in 2011. China accounts for more than 50% of this output, followed by India (14% in 2011), Morocco (8.3%), US (8.2%), Turkey (2.5%), Iran and Kazakhstan (2.6% each). + +The mined ore is washed, crushed, classified, and separated from quartz. If the quartz penetrates too deeply into the ore, or the iron, zinc, or lead content is abnormally high, then froth flotation is used. The product is a 98% pure baryte (by mass); the purity should be no less than 95%, with a minimal content of iron and silicon dioxide. It is then reduced by carbon to barium sulfide: +BaSO4 + 2 C → BaS + 2 CO2 + +The water-soluble barium sulfide is the starting point for other compounds: treating BaS with oxygen produces the sulfate, with nitric acid the nitrate, with aqueous carbon dioxide the carbonate, and so on. The nitrate can be thermally decomposed to yield the oxide. Barium metal is produced by reduction with aluminium at . The intermetallic compound BaAl4 is produced first: +3 BaO + 14 Al → 3 BaAl4 + Al2O3 + +BaAl4 is an intermediate reacted with barium oxide to produce the metal. Note that not all barium is reduced. +8 BaO + BaAl4 → Ba↓ + 7 BaAl2O4 + +The remaining barium oxide reacts with the formed aluminium oxide: +BaO + Al2O3 → BaAl2O4 + +and the overall reaction is +4 BaO + 2 Al → 3 Ba↓ + BaAl2O4 + +Barium vapor is condensed and packed into molds in an atmosphere of argon. This method is used commercially, yielding ultrapure barium. Commonly sold barium is about 99% pure, with main impurities being strontium and calcium (up to 0.8% and 0.25%) and other contaminants contributing less than 0.1%. + +A similar reaction with silicon at yields barium and barium metasilicate. Electrolysis is not used because barium readily dissolves in molten halides and the product is rather impure. + +Gemstone +The barium mineral, benitoite (barium titanium silicate), occurs as a very rare blue fluorescent gemstone, and is the official state gem of California. + +Barium in seawater + +Barium exists in seawater as the Ba2+ ion with an average oceanic concentration of 109 nmol/kg. Barium also exists in the ocean as BaSO4, or barite. Barium has a nutrient-like profile with a residence time of 10,000 years. + +Barium shows a relatively consistent concentration in upper ocean seawater, excepting regions of high river inputs and regions with strong upwelling. There is little depletion of barium concentrations in the upper ocean for an ion with a nutrient-like profile, thus lateral mixing is important. Barium isotopic values show basin-scale balances instead of local or short-term processes. + +Applications + +Metal and alloys +Barium, as a metal or when alloyed with aluminium, is used to remove unwanted gases (gettering) from vacuum tubes, such as TV picture tubes. Barium is suitable for this purpose because of its low vapor pressure and reactivity towards oxygen, nitrogen, carbon dioxide, and water; it can even partly remove noble gases by dissolving them in the crystal lattice. This application is gradually disappearing due to the rising popularity of the tubeless LCD, LED, and plasma sets. + +Other uses of elemental barium are minor and include an additive to silumin (aluminium–silicon alloys) that refines their structure, as well as + bearing alloys; + lead–tin soldering alloys – to increase the creep resistance; + alloy with nickel for spark plugs; + additive to steel and cast iron as an inoculant; + alloys with calcium, manganese, silicon, and aluminium as high-grade steel deoxidizers. + +Barium sulfate and baryte + +Barium sulfate (the mineral baryte, BaSO4) is important to the petroleum industry as a drilling fluid in oil and gas wells. The precipitate of the compound (called "blanc fixe", from the French for "permanent white") is used in paints and varnishes; as a filler in ringing ink, plastics, and rubbers; as a paper coating pigment; and in nanoparticles, to improve physical properties of some polymers, such as epoxies. + +Barium sulfate has a low toxicity and relatively high density of ca. 4.5 g/cm3 (and thus opacity to X-rays). For this reason it is used as a radiocontrast agent in X-ray imaging of the digestive system ("barium meals" and "barium enemas"). Lithopone, a pigment that contains barium sulfate and zinc sulfide, is a permanent white with good covering power that does not darken when exposed to sulfides. + +Other barium compounds + +Other compounds of barium find only niche applications, limited by the toxicity of Ba2+ ions (barium carbonate is a rat poison), which is not a problem for the insoluble BaSO4. + Barium oxide coating on the electrodes of fluorescent lamps facilitates the release of electrons. + By its great atomic density, barium carbonate increases the refractive index and luster of glass and reduces leaks of X-rays from cathode ray tubes (CRT) TV sets. + Barium, typically as barium nitrate imparts a yellow or "apple" green color to fireworks; for brilliant green barium monochloride is used. + Barium peroxide is a catalyst in the aluminothermic reaction (thermite) for welding rail tracks. It is also a green flare in tracer ammunition and a bleaching agent. + Barium titanate is a promising electroceramic. + Barium fluoride is used for optics in infrared applications because of its wide transparency range of 0.15–12 micrometers. + YBCO was the first high-temperature superconductor cooled by liquid nitrogen, with a transition temperature of that exceeded the boiling point of nitrogen (). + Ferrite, a type of sintered ceramic composed of iron oxide (Fe2O3) and barium oxide (BaO), is both electrically nonconductive and ferrimagnetic, and can be temporarily or permanently magnetized. +Palaeoceanography + +The lateral mixing of barium is caused by water mass mixing and ocean circulation. Global ocean circulation reveals a strong correlation between dissolved barium and silicic acid. The large-scale ocean circulation combined with remineralization of barium show a similar correlation between dissolved barium and ocean alkalinity. + +Dissolved barium's correlation with silicic acid can be seen both vertically and spatially. Particulate barium shows a strong correlation with particulate organic carbon or POC. Barium is becoming more popular to be used a base for palaeoceanographic proxies. With both dissolved and particulate barium's links with silicic acid and POC, it can be used to determine historical variations in the biological pump, carbon cycle, and global climate. + +The barium particulate barite (BaSO4), as one of many proxies, can be used to provide a host of historical information on processes in different oceanic settings (water column, sediments, and hydrothermal sites). In each setting there are differences in isotopic and elemental composition of the barite particulate. Barite in the water column, known as marine or pelagic barite, reveals information on seawater chemistry variation over time. Barite in sediments, known as diagenetic or cold seeps barite, gives information about sedimentary redox processes. Barite formed via hydrothermal activity at hydrothermal vents, known as hydrothermal barite, reveals alterations in the condition of the earth's crust around those vents. + +Toxicity + +Because of the high reactivity of the metal, toxicological data are available only for compounds. Soluble barium compounds are poisonous. In low doses, barium ions act as a muscle stimulant, and higher doses affect the nervous system, causing cardiac irregularities, tremors, weakness, anxiety, shortness of breath, and paralysis. This toxicity may be caused by Ba2+ blocking potassium ion channels, which are critical to the proper function of the nervous system. Other organs damaged by water-soluble barium compounds (i.e., barium ions) are the eyes, immune system, heart, respiratory system, and skin causing, for example, blindness and sensitization. + +Barium is not carcinogenic and does not bioaccumulate. Inhaled dust containing insoluble barium compounds can accumulate in the lungs, causing a benign condition called baritosis. The insoluble sulfate is nontoxic and is not classified as a dangerous goods in transport regulations. + +To avoid a potentially vigorous chemical reaction, barium metal is kept in an argon atmosphere or under mineral oils. Contact with air is dangerous and may cause ignition. Moisture, friction, heat, sparks, flames, shocks, static electricity, and exposure to oxidizers and acids should be avoided. Anything that may contact with barium should be electrically grounded. + +See also + Han purple and Han blue – synthetic barium copper silicate pigments developed and used in ancient and imperial China + +References + +External links + Barium at The Periodic Table of Videos (University of Nottingham) + Elementymology & Elements Multidict + 3-D Holographic Display Using Strontium Barium Niobate + + +Chemical elements +Alkaline earth metals +Toxicology +Reducing agents +Chemical elements with body-centered cubic structure +Berkelium is a transuranic radioactive chemical element with the symbol Bk and atomic number 97. It is a member of the actinide and transuranium element series. It is named after the city of Berkeley, California, the location of the Lawrence Berkeley National Laboratory (then the University of California Radiation Laboratory) where it was discovered in December 1949. Berkelium was the fifth transuranium element discovered after neptunium, plutonium, curium and americium. + +The major isotope of berkelium, 249Bk, is synthesized in minute quantities in dedicated high-flux nuclear reactors, mainly at the Oak Ridge National Laboratory in Tennessee, United States, and at the Research Institute of Atomic Reactors in Dimitrovgrad, Russia. The longest-lived and second-most important isotope, 247Bk, can be synthesized via irradiation of 244Cm with high-energy alpha particles. + +Just over one gram of berkelium has been produced in the United States since 1967. There is no practical application of berkelium outside scientific research which is mostly directed at the synthesis of heavier transuranium elements and superheavy elements. A 22-milligram batch of berkelium-249 was prepared during a 250-day irradiation period and then purified for a further 90 days at Oak Ridge in 2009. This sample was used to synthesize the new element tennessine for the first time in 2009 at the Joint Institute for Nuclear Research, Russia, after it was bombarded with calcium-48 ions for 150 days. This was the culmination of the Russia–US collaboration on the synthesis of the heaviest elements on the periodic table. + +Berkelium is a soft, silvery-white, radioactive metal. The berkelium-249 isotope emits low-energy electrons and thus is relatively safe to handle. It decays with a half-life of 330 days to californium-249, which is a strong emitter of ionizing alpha particles. This gradual transformation is an important consideration when studying the properties of elemental berkelium and its chemical compounds, since the formation of californium brings not only chemical contamination, but also free-radical effects and self-heating from the emitted alpha particles. + +Characteristics + +Physical + +Berkelium is a soft, silvery-white, radioactive actinide metal. In the periodic table, it is located to the right of the actinide curium, to the left of the actinide californium and below the lanthanide terbium with which it shares many similarities in physical and chemical properties. Its density of 14.78 g/cm3 lies between those of curium (13.52 g/cm3) and californium (15.1 g/cm3), as does its melting point of 986 °C, below that of curium (1340 °C) but higher than that of californium (900 °C). Berkelium is relatively soft and has one of the lowest bulk moduli among the actinides, at about 20 GPa (2 Pa). + + ions shows two sharp fluorescence peaks at 652 nanometers (red light) and 742 nanometers (deep red – near-infrared) due to internal transitions at the f-electron shell. The relative intensity of these peaks depends on the excitation power and temperature of the sample. This emission can be observed, for example, after dispersing berkelium ions in a silicate glass, by melting the glass in presence of berkelium oxide or halide. + +Between 70 K and room temperature, berkelium behaves as a Curie–Weiss paramagnetic material with an effective magnetic moment of 9.69 Bohr magnetons (µB) and a Curie temperature of 101 K. This magnetic moment is almost equal to the theoretical value of 9.72 µB calculated within the simple atomic L-S coupling model. Upon cooling to about 34 K, berkelium undergoes a transition to an antiferromagnetic state. Enthalpy of dissolution in hydrochloric acid at standard conditions is −600 kJ/mol, from which the standard enthalpy of formation (ΔfH°) of aqueous ions is obtained as −601 kJ/mol. The standard electrode potential /Bk is −2.01 V. The ionization potential of a neutral berkelium atom is 6.23 eV. + +Allotropes +At ambient conditions, berkelium assumes its most stable α form which has a hexagonal symmetry, space group P63/mmc, lattice parameters of 341 pm and 1107 pm. The crystal has a double-hexagonal close packing structure with the layer sequence ABAC and so is isotypic (having a similar structure) with α-lanthanum and α-forms of actinides beyond curium. This crystal structure changes with pressure and temperature. When compressed at room temperature to 7 GPa, α-berkelium transforms to the β modification, which has a face-centered cubic (fcc) symmetry and space group Fmm. This transition occurs without change in volume, but the enthalpy increases by 3.66 kJ/mol. Upon further compression to 25 GPa, berkelium transforms to an orthorhombic γ-berkelium structure similar to that of α-uranium. This transition is accompanied by a 12% volume decrease and delocalization of the electrons at the 5f electron shell. No further phase transitions are observed up to 57 GPa. + +Upon heating, α-berkelium transforms into another phase with an fcc lattice (but slightly different from β-berkelium), space group Fmm and the lattice constant of 500 pm; this fcc structure is equivalent to the closest packing with the sequence ABC. This phase is metastable and will gradually revert to the original α-berkelium phase at room temperature. The temperature of the phase transition is believed to be quite close to the melting point. + +Chemical +Like all actinides, berkelium dissolves in various aqueous inorganic acids, liberating gaseous hydrogen and converting into the state. This trivalent oxidation state (+3) is the most stable, especially in aqueous solutions, but tetravalent (+4), pentavalent (+5), and possibly divalent (+2) berkelium compounds are also known. The existence of divalent berkelium salts is uncertain and has only been reported in mixed lanthanum(III) chloride-strontium chloride melts. A similar behavior is observed for the lanthanide analogue of berkelium, terbium. Aqueous solutions of ions are green in most acids. The color of ions is yellow in hydrochloric acid and orange-yellow in sulfuric acid. Berkelium does not react rapidly with oxygen at room temperature, possibly due to the formation of a protective oxide layer surface. However, it reacts with molten metals, hydrogen, halogens, chalcogens and pnictogens to form various binary compounds. + +Isotopes + +Nineteen isotopes and six nuclear isomers (excited states of an isotope) of berkelium have been characterized, with mass numbers ranging from 233 to 253 (except 235 and 237). All of them are radioactive. The longest half-lives are observed for 247Bk (1,380 years), 248Bk (over 300 years), and 249Bk (330 days); the half-lives of the other isotopes range from microseconds to several days. The isotope which is the easiest to synthesize is berkelium-249. This emits mostly soft β-particles which are inconvenient for detection. Its alpha radiation is rather weak (1.45%) with respect to the β-radiation, but is sometimes used to detect this isotope. The second important berkelium isotope, berkelium-247, is an alpha-emitter, as are most actinide isotopes. + +Occurrence +All berkelium isotopes have a half-life far too short to be primordial. Therefore, any primordial berkelium − that is, berkelium present on the Earth during its formation − has decayed by now. + +On Earth, berkelium is mostly concentrated in certain areas, which were used for the atmospheric nuclear weapons tests between 1945 and 1980, as well as at the sites of nuclear incidents, such as the Chernobyl disaster, Three Mile Island accident and 1968 Thule Air Base B-52 crash. Analysis of the debris at the testing site of the first United States' first thermonuclear weapon, Ivy Mike, (1 November 1952, Enewetak Atoll), revealed high concentrations of various actinides, including berkelium. For reasons of military secrecy, this result was not published until 1956. + +Nuclear reactors produce mostly, among the berkelium isotopes, berkelium-249. During the storage and before the fuel disposal, most of it beta decays to californium-249. The latter has a half-life of 351 years, which is relatively long compared to the half-lives of other isotopes produced in the reactor, and is therefore undesirable in the disposal products. + +The transuranium elements from americium to fermium, including berkelium, occurred naturally in the natural nuclear fission reactor at Oklo, but no longer do so. + +Berkelium is also one of the elements that have theoretically been detected in Przybylski's Star. + +History + +Although very small amounts of berkelium were possibly produced in previous nuclear experiments, it was first intentionally synthesized, isolated and identified in December 1949 by Glenn T. Seaborg, Albert Ghiorso, Stanley Gerald Thompson, and Kenneth Street Jr. They used the 60-inch cyclotron at the University of California, Berkeley. Similar to the nearly simultaneous discovery of americium (element 95) and curium (element 96) in 1944, the new elements berkelium and californium (element 98) were both produced in 1949–1950. + +The name choice for element 97 followed the previous tradition of the Californian group to draw an analogy between the newly discovered actinide and the lanthanide element positioned above it in the periodic table. Previously, americium was named after a continent as its analogue europium, and curium honored scientists Marie and Pierre Curie as the lanthanide above it, gadolinium, was named after the explorer of the rare-earth elements Johan Gadolin. Thus the discovery report by the Berkeley group reads: "It is suggested that element 97 be given the name berkelium (symbol Bk) after the city of Berkeley in a manner similar to that used in naming its chemical homologue terbium (atomic number 65) whose name was derived from the town of Ytterby, Sweden, where the rare earth minerals were first found." This tradition ended with berkelium, though, as the naming of the next discovered actinide, californium, was not related to its lanthanide analogue dysprosium, but after the discovery place. + +The most difficult steps in the synthesis of berkelium were its separation from the final products and the production of sufficient quantities of americium for the target material. First, americium (241Am) nitrate solution was coated on a platinum foil, the solution was evaporated and the residue converted by annealing to americium dioxide (). This target was irradiated with 35 MeV alpha particles for 6 hours in the 60-inch cyclotron at the Lawrence Radiation Laboratory, University of California, Berkeley. The (α,2n) reaction induced by the irradiation yielded the 243Bk isotope and two free neutrons: + + + → + 2 + +After the irradiation, the coating was dissolved with nitric acid and then precipitated as the hydroxide using concentrated aqueous ammonia solution. The product was centrifugated and re-dissolved in nitric acid. To separate berkelium from the unreacted americium, this solution was added to a mixture of ammonium and ammonium sulfate and heated to convert all the dissolved americium into the oxidation state +6. Unoxidized residual americium was precipitated by the addition of hydrofluoric acid as americium(III) fluoride (). This step yielded a mixture of the accompanying product curium and the expected element 97 in form of trifluorides. The mixture was converted to the corresponding hydroxides by treating it with potassium hydroxide, and after centrifugation, was dissolved in perchloric acid. + +Further separation was carried out in the presence of a citric acid/ammonium buffer solution in a weakly acidic medium (pH≈3.5), using ion exchange at elevated temperature. The chromatographic separation behavior was unknown for the element 97 at the time, but was anticipated by analogy with terbium. The first results were disappointing because no alpha-particle emission signature could be detected from the elution product. With further analysis, searching for characteristic X-rays and conversion electron signals, a berkelium isotope was eventually detected. Its mass number was uncertain between 243 and 244 in the initial report, but was later established as 243. + +Synthesis and extraction + +Preparation of isotopes +Berkelium is produced by bombarding lighter actinides uranium (238U) or plutonium (239Pu) with neutrons in a nuclear reactor. In a more common case of uranium fuel, plutonium is produced first by neutron capture (the so-called (n,γ) reaction or neutron fusion) followed by beta-decay: + +^{238}_{92}U ->[\ce{(n,\gamma)}] ^{239}_{92}U ->[\beta^-][23.5 \ \ce{min}] ^{239}_{93}Np ->[\beta^-][2.3565 \ \ce{d}] ^{239}_{94}Pu (the times are half-lives) + +Plutonium-239 is further irradiated by a source that has a high neutron flux, several times higher than a conventional nuclear reactor, such as the 85-megawatt High Flux Isotope Reactor (HFIR) at the Oak Ridge National Laboratory in Tennessee, USA. The higher flux promotes fusion reactions involving not one but several neutrons, converting 239Pu to 244Cm and then to 249Cm: + +Curium-249 has a short half-life of 64 minutes, and thus its further conversion to 250Cm has a low probability. Instead, it transforms by beta-decay into 249Bk: +^{249}_{96}Cm ->[{\beta^-}][64.15 \ \ce{min}] ^{249}_{97}Bk ->[\beta^-][330 \ \ce{d}] ^{249}_{98}Cf + +The thus-produced 249Bk has a long half-life of 330 days and thus can capture another neutron. However, the product, 250Bk, again has a relatively short half-life of 3.212 hours and thus does not yield any heavier berkelium isotopes. It instead decays to the californium isotope 250Cf: +^{249}_{97}Bk ->[\ce{(n,\gamma)}] ^{250}_{97}Bk ->[\beta^-][3.212 \ \ce{h}] ^{250}_{98}Cf + +Although 247Bk is the most stable isotope of berkelium, its production in nuclear reactors is very difficult because its potential progenitor 247Cm has never been observed to undergo beta decay. Thus, 249Bk is the most accessible isotope of berkelium, which still is available only in small quantities (only 0.66 grams have been produced in the US over the period 1967–1983) at a high price of the order 185 USD per microgram. It is the only berkelium isotope available in bulk quantities, and thus the only berkelium isotope whose properties can be extensively studied. + +The isotope 248Bk was first obtained in 1956 by bombarding a mixture of curium isotopes with 25 MeV α-particles. Although its direct detection was hindered by strong signal interference with 245Bk, the existence of a new isotope was proven by the growth of the decay product 248Cf which had been previously characterized. The half-life of 248Bk was estimated as hours, though later 1965 work gave a half-life in excess of 300 years (which may be due to an isomeric state). Berkelium-247 was produced during the same year by irradiating 244Cm with alpha-particles: + +Berkelium-242 was synthesized in 1979 by bombarding 235U with 11B, 238U with 10B, 232Th with 14N or 232Th with 15N. It converts by electron capture to 242Cm with a half-life of minutes. A search for an initially suspected isotope 241Bk was then unsuccessful; 241Bk has since been synthesized. + +Separation +The fact that berkelium readily assumes oxidation state +4 in solids, and is relatively stable in this state in liquids greatly assists separation of berkelium away from many other actinides. These are inevitably produced in relatively large amounts during the nuclear synthesis and often favor the +3 state. This fact was not yet known in the initial experiments, which used a more complex separation procedure. Various inorganic oxidation agents can be applied to the solutions to convert it to the +4 state, such as bromates (), bismuthates (), chromates ( and ), silver(I) thiolate (), lead(IV) oxide (), ozone (), or photochemical oxidation procedures. More recently, it has been discovered that some organic and bio-inspired molecules, such as the chelator called 3,4,3-LI(1,2-HOPO), can also oxidize Bk(III) and stabilize Bk(IV) under mild conditions. is then extracted with ion exchange, extraction chromatography or liquid-liquid extraction using HDEHP (bis-(2-ethylhexyl) phosphoric acid), amines, tributyl phosphate or various other reagents. These procedures separate berkelium from most trivalent actinides and lanthanides, except for the lanthanide cerium (lanthanides are absent in the irradiation target but are created in various nuclear fission decay chains). + +A more detailed procedure adopted at the Oak Ridge National Laboratory was as follows: the initial mixture of actinides is processed with ion exchange using lithium chloride reagent, then precipitated as hydroxides, filtered and dissolved in nitric acid. It is then treated with high-pressure elution from cation exchange resins, and the berkelium phase is oxidized and extracted using one of the procedures described above. Reduction of the thus-obtained to the +3 oxidation state yields a solution, which is nearly free from other actinides (but contains cerium). Berkelium and cerium are then separated with another round of ion-exchange treatment. + +Bulk metal preparation +In order to characterize chemical and physical properties of solid berkelium and its compounds, a program was initiated in 1952 at the Material Testing Reactor, Arco, Idaho, US. It resulted in preparation of an eight-gram plutonium-239 target and in the first production of macroscopic quantities (0.6 micrograms) of berkelium by Burris B. Cunningham and Stanley Gerald Thompson in 1958, after a continuous reactor irradiation of this target for six years. This irradiation method was and still is the only way of producing weighable amounts of the element, and most solid-state studies of berkelium have been conducted on microgram or submicrogram-sized samples. + +The world's major irradiation sources are the 85-megawatt High Flux Isotope Reactor at the Oak Ridge National Laboratory in Tennessee, USA, and the SM-2 loop reactor at the Research Institute of Atomic Reactors (NIIAR) in Dimitrovgrad, Russia, which are both dedicated to the production of transcurium elements (atomic number greater than 96). These facilities have similar power and flux levels, and are expected to have comparable production capacities for transcurium elements, although the quantities produced at NIIAR are not publicly reported. In a "typical processing campaign" at Oak Ridge, tens of grams of curium are irradiated to produce decigram quantities of californium, milligram quantities of berkelium-249 and einsteinium, and picogram quantities of fermium. In total, just over one gram of berkelium-249 has been produced at Oak Ridge since 1967. + +The first berkelium metal sample weighing 1.7 micrograms was prepared in 1971 by the reduction of fluoride with lithium vapor at 1000 °C; the fluoride was suspended on a tungsten wire above a tantalum crucible containing molten lithium. Later, metal samples weighing up to 0.5 milligrams were obtained with this method. + +Similar results are obtained with fluoride. Berkelium metal can also be produced by the reduction of oxide with thorium or lanthanum. + +Compounds + +Oxides +Two oxides of berkelium are known, with the berkelium oxidation state of +3 () and +4 (). oxide is a brown solid, while oxide is a yellow-green solid with a melting point of 1920 °C and is formed from BkO2 by reduction with molecular hydrogen: + +Upon heating to 1200 °C, the oxide undergoes a phase change; it undergoes another phase change at 1750 °C. Such three-phase behavior is typical for the actinide sesquioxides. oxide, BkO, has been reported as a brittle gray solid but its exact chemical composition remains uncertain. + +Halides +In halides, berkelium assumes the oxidation states +3 and +4. The +3 state is the most stable, especially in solutions, while the tetravalent halides and are only known in the solid phase. The coordination of berkelium atom in its trivalent fluoride and chloride is tricapped trigonal prismatic, with the coordination number of 9. In trivalent bromide, it is bicapped trigonal prismatic (coordination 8) or octahedral (coordination 6), and in the iodide it is octahedral. + + fluoride () is a yellow-green ionic solid and is isotypic with uranium tetrafluoride or zirconium tetrafluoride. fluoride () is also a yellow-green solid, but it has two crystalline structures. The most stable phase at low temperatures is isotypic with yttrium(III) fluoride, while upon heating to between 350 and 600 °C, it transforms to the structure found in lanthanum trifluoride. + +Visible amounts of chloride () were first isolated and characterized in 1962, and weighed only 3 billionths of a gram. It can be prepared by introducing hydrogen chloride vapors into an evacuated quartz tube containing berkelium oxide at a temperature about 500 °C. This green solid has a melting point of 600 °C, and is isotypic with uranium(III) chloride. Upon heating to nearly melting point, converts into an orthorhombic phase. + +Two forms of bromide are known: one with berkelium having coordination 6, and one with coordination 8. The latter is less stable and transforms to the former phase upon heating to about 350 °C. An important phenomenon for radioactive solids has been studied on these two crystal forms: the structure of fresh and aged 249BkBr3 samples was probed by X-ray diffraction over a period longer than 3 years, so that various fractions of berkelium-249 had beta decayed to californium-249. No change in structure was observed upon the 249BkBr3—249CfBr3 transformation. However, other differences were noted for 249BkBr3 and 249CfBr3. For example, the latter could be reduced with hydrogen to 249CfBr2, but the former could not – this result was reproduced on individual 249BkBr3 and 249CfBr3 samples, as well on the samples containing both bromides. The intergrowth of californium in berkelium occurs at a rate of 0.22% per day and is an intrinsic obstacle in studying berkelium properties. Beside a chemical contamination, 249Cf, being an alpha emitter, brings undesirable self-damage of the crystal lattice and the resulting self-heating. The chemical effect however can be avoided by performing measurements as a function of time and extrapolating the obtained results. + +Other inorganic compounds +The pnictides of berkelium-249 of the type BkX are known for the elements nitrogen, phosphorus, arsenic and antimony. They crystallize in the rock-salt structure and are prepared by the reaction of either hydride () or metallic berkelium with these elements at elevated temperature (about 600 °C) under high vacuum. + + sulfide, , is prepared by either treating berkelium oxide with a mixture of hydrogen sulfide and carbon disulfide vapors at 1130 °C, or by directly reacting metallic berkelium with elemental sulfur. These procedures yield brownish-black crystals. + + and hydroxides are both stable in 1 molar solutions of sodium hydroxide. phosphate () has been prepared as a solid, which shows strong fluorescence under excitation with a green light. Berkelium hydrides are produced by reacting metal with hydrogen gas at temperatures about 250 °C. They are non-stoichiometric with the nominal formula (0 < x < 1). Several other salts of berkelium are known, including an oxysulfide (), and hydrated nitrate (), chloride (), sulfate () and oxalate (). Thermal decomposition at about 600 °C in an argon atmosphere (to avoid oxidation to ) of yields the crystals of oxysulfate (). This compound is thermally stable to at least 1000 °C in inert atmosphere. + +Organoberkelium compounds +Berkelium forms a trigonal (η5–C5H5)3Bk metallocene complex with three cyclopentadienyl rings, which can be synthesized by reacting chloride with the molten beryllocene () at about 70 °C. It has an amber color and a density of 2.47 g/cm3. The complex is stable to heating to at least 250 °C, and sublimates without melting at about 350 °C. The high radioactivity of berkelium gradually destroys the compound (within a period of weeks). One cyclopentadienyl ring in (η5–C5H5)3Bk can be substituted by chlorine to yield . The optical absorption spectra of this compound are very similar to those of (η5–C5H5)3Bk. + +Applications + +There is currently no use for any isotope of berkelium outside basic scientific research. Berkelium-249 is a common target nuclide to prepare still heavier transuranium elements and superheavy elements, such as lawrencium, rutherfordium and bohrium. It is also useful as a source of the isotope californium-249, which is used for studies on the chemistry of californium in preference to the more radioactive californium-252 that is produced in neutron bombardment facilities such as the HFIR. + +A 22 milligram batch of berkelium-249 was prepared in a 250-day irradiation and then purified for 90 days at Oak Ridge in 2009. This target yielded the first 6 atoms of tennessine at the Joint Institute for Nuclear Research (JINR), Dubna, Russia, after bombarding it with calcium ions in the U400 cyclotron for 150 days. This synthesis was a culmination of the Russia-US collaboration between JINR and Lawrence Livermore National Laboratory on the synthesis of elements 113 to 118 which was initiated in 1989. + +Nuclear fuel cycle +The nuclear fission properties of berkelium are different from those of the neighboring actinides curium and californium, and they suggest berkelium to perform poorly as a fuel in a nuclear reactor. Specifically, berkelium-249 has a moderately large neutron capture cross section of 710 barns for thermal neutrons, 1200 barns resonance integral, but very low fission cross section for thermal neutrons. In a thermal reactor, much of it will therefore be converted to berkelium-250 which quickly decays to californium-250. In principle, berkelium-249 can sustain a nuclear chain reaction in a fast breeder reactor. Its critical mass is relatively high at 192 kg; it can be reduced with a water or steel reflector but would still exceed the world production of this isotope. + +Berkelium-247 can maintain chain reaction both in a thermal-neutron and in a fast-neutron reactor, however, its production is rather complex and thus the availability is much lower than its critical mass, which is about 75.7 kg for a bare sphere, 41.2 kg with a water reflector and 35.2 kg with a steel reflector (30 cm thickness). + +Health issues +Little is known about the effects of berkelium on human body, and analogies with other elements may not be drawn because of different radiation products (electrons for berkelium and alpha particles, neutrons, or both for most other actinides). The low energy of electrons emitted from berkelium-249 (less than 126 keV) hinders its detection, due to signal interference with other decay processes, but also makes this isotope relatively harmless to humans as compared to other actinides. However, berkelium-249 transforms with a half-life of only 330 days to the strong alpha-emitter californium-249, which is rather dangerous and has to be handled in a glovebox in a dedicated laboratory. + +Most available berkelium toxicity data originate from research on animals. Upon ingestion by rats, only about 0.01% of berkelium ends in the blood stream. From there, about 65% goes to the bones, where it remains for about 50 years, 25% to the lungs (biological half-life about 20 years), 0.035% to the testicles or 0.01% to the ovaries where berkelium stays indefinitely. The balance of about 10% is excreted. In all these organs berkelium might promote cancer, and in the skeleton, its radiation can damage red blood cells. The maximum permissible amount of berkelium-249 in the human skeleton is 0.4 nanograms. + +References + +Bibliography + +External links + Berkelium at The Periodic Table of Videos (University of Nottingham) + + +Chemical elements +Chemical elements with double hexagonal close-packed structure +Actinides +Synthetic elements +Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH)3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe2O3), the aluminium clay mineral kaolinite (Al2Si2O5(OH)4) and small amounts of anatase (TiO2) and ilmenite (FeTiO3 or FeO.TiO2). +Bauxite appears dull in luster and is reddish-brown, white, or tan. + +In 1821, the French geologist Pierre Berthier discovered bauxite near the village of Les Baux in Provence, southern France. + +Formation + +Numerous classification schemes have been proposed for bauxite but, , there was no consensus. + +Vadász (1951) distinguished lateritic bauxites (silicate bauxites) from karst bauxite ores (carbonate bauxites): + + The carbonate bauxites occur predominantly in Europe, Guyana, Suriname, and Jamaica above carbonate rocks (limestone and dolomite), where they were formed by lateritic weathering and residual accumulation of intercalated clay layers – dispersed clays which were concentrated as the enclosing limestones gradually dissolved during chemical weathering. + The lateritic bauxites are found mostly in the countries of the tropics. They were formed by lateritization of various silicate rocks such as granite, gneiss, basalt, syenite, and shale. In comparison with the iron-rich laterites, the formation of bauxites depends even more on intense weathering conditions in a location with very good drainage. This enables the dissolution of the kaolinite and the precipitation of the gibbsite. Zones with highest aluminium content are frequently located below a ferruginous surface layer. The aluminium hydroxide in the lateritic bauxite deposits is almost exclusively gibbsite. + +In the case of Jamaica, recent analysis of the soils showed elevated levels of cadmium, suggesting that the bauxite originates from Miocene volcanic ash deposits from episodes of significant volcanism in Central America. + +Production and reserves + +Australia is the largest producer of bauxite, followed by Guinea and China. Bauxite is usually strip mined because it is almost always found near the surface of the terrain, with little or no overburden. Increased aluminium recycling, which requires less electric power than producing aluminium from ores, will considerably extend the world's bauxite reserves. + +Aluminium production + +, approximately 70% to 80% of the world's dry bauxite production is processed first into alumina and then into aluminium by electrolysis. Bauxite rocks are typically classified according to their intended commercial application: metallurgical, abrasive, cement, chemical, and refractory. + +Bauxite ore is usually heated in a pressure vessel along with a sodium hydroxide solution at a temperature of . At these temperatures, the aluminium is dissolved as sodium aluminate (the Bayer process). The aluminium compounds in the bauxite may be present as gibbsite(Al(OH)3), boehmite(AlOOH) or diaspore(AlOOH); the different forms of the aluminium component will dictate the extraction conditions. The undissolved waste, bauxite tailings, after the aluminium compounds are extracted contains iron oxides, silica, calcia, titania and some un-reacted alumina. After separation of the residue by filtering, pure gibbsite is precipitated when the liquid is cooled, and then seeded with fine-grained aluminium hydroxide. The gibbsite is usually converted into aluminium oxide, Al2O3, by heating in rotary kilns or fluid flash calciners to a temperature in excess of . This aluminium oxide is dissolved at a temperature of about in molten cryolite. Next, this molten substance can yield metallic aluminium by passing an electric current through it in the process of electrolysis, which is called the Hall–Héroult process, named after its American and French discoverers. + +Prior to the invention of this process, and prior to the Deville process, aluminium ore was refined by heating ore along with elemental sodium or potassium in a vacuum. The method was complicated and consumed materials that were themselves expensive at that time. This made early elemental aluminium more expensive than gold. + +Maritime safety +As a bulk cargo, bauxite is a Group A cargo that may liquefy if excessively moist. Liquefaction and the free surface effect can cause the cargo to shift rapidly inside the hold and make the ship unstable, potentially sinking the ship. One vessel suspected to have been sunk in this way was the MS Bulk Jupiter in 2015. One method which can demonstrate this effect is the "can test", in which a sample of the material is placed in a cylindrical can and struck against a surface many times. If a moist slurry forms in the can, then there is a likelihood for the cargo to liquefy; although conversely, even if the sample remains dry it does not conclusively prove that it will remain that way, or that it is safe for loading. + +Source of gallium +Bauxite is the main source of the rare metal gallium. + +During the processing of bauxite to alumina in the Bayer process, gallium accumulates in the sodium hydroxide liquor. From this it can be extracted by a variety of methods. The most recent is the use of ion-exchange resin. Achievable extraction efficiencies critically depend on the original concentration in the feed bauxite. At a typical feed concentration of 50 ppm, about 15 percent of the contained gallium is extractable. The remainder reports to the red mud and aluminium hydroxide streams. + +Bauxite is also a potential source for vanadium. + +See also +Bauxite, Arkansas +Rio Tinto Alcan +United Company RUSAL +MS Bulk Jupiter + +References + +Further reading +Bárdossy, G.

With an area of , Bavaria is the largest German state by land area, comprising roughly a fifth of the total land area of Germany. With over 13 million inhabitants, it is the second largest German state in terms of population only to North Rhine-Westphalia, but due to its large size its population density is below the German average. Major cities include Munich (its capital and largest city, which is also the third largest city in Germany), Nuremberg, and Augsburg. + +The history of Bavaria includes its earliest settlement by Iron Age Celtic tribes, followed by the conquests of the Roman Empire in the 1st century BC, when the territory was incorporated into the provinces of Raetia and Noricum. It became the Duchy of Bavaria (a stem duchy) in the 6th century AD following the collapse of the Western Roman Empire. It was later incorporated into the Holy Roman Empire, became an independent kingdom after 1806, joined the Prussian-led German Empire in 1871 while retaining its title of kingdom, and finally became a state of the Federal Republic of Germany in 1949. + +Bavaria has a distinct culture, largely because of the state's Catholic heritage and conservative traditions, which includes a language, cuisine, architecture, festivals and elements of Alpine symbolism. The state also has the second largest economy among the German states by GDP figures, giving it the status of a wealthy German region. + +Contemporary Bavaria also includes parts of the historical regions of Franconia and Swabia, in addition to Altbayern. + +History + +Antiquity +The Celts settled in the Bavarian Alps, also known as Celto-Slavs or Alpines, these peoples were famed, romanticized, and subjected to ancientness. + +Middle Ages +In the 530s, the Merovingian dynasty incorporated the kingdom of Thuringia after their defeat by the Franks. The Baiuvarii were Frankicised a century later. The Lex Thuringorum documents an upper class nobility of adalingi. From about 554 to 788, the house of Agilolfing ruled the Duchy of Bavaria, ending with Tassilo III who was deposed by Charlemagne. + +Tassilo I of Bavaria tried unsuccessfully to hold the eastern frontier against the expansion of Slavic peoples and the Pannonian Avars around 600. Garibald II seems to have achieved a balance of power between 610 and 616. + +At Hugbert's death in 735, the duchy passed to Odilo of Bavaria from the neighboring Alemannia. Odilo issued a Lex Baiuvariorum for Bavaria, completed the process of church organization in partnership with Saint Boniface in 739, and tried to intervene in Frankish succession disputes by fighting for the claims of the Carolingian dynasty. He was defeated near Augsburg in 743 but continued to rule until his death in 748. + +Saint Boniface completed the people's conversion to Christianity in the early 8th century. Tassilo III of Bavaria succeeded to rule Bavaria. He initially ruled under Frankish oversight but began to function independently from 763 onward. He was particularly noted for founding new monasteries and for expanding eastwards, fighting Slavs in the eastern Alps and along the Danube and colonizing these lands. After 781, however, Charlemagne began to exert pressure and Tassilo III was deposed in 788. Dissenters attempted a coup against Charlemagne at Regensburg in 792, led by Pepin the Hunchback. + +With the revolt of Henry II, Duke of Bavaria in 976, Bavaria lost large territories in the south and southeast. + +One of the most important dukes of Bavaria was Henry the Lion of the house of Welf, founder of Munich, and de facto the second most powerful man in the empire as the ruler of two duchies. When in 1180, Henry the Lion was deposed as Duke of Saxony and Bavaria by his cousin, Frederick I, Holy Roman Emperor (a.k.a. "Barbarossa" for his red beard), Bavaria was awarded as fief to the Wittelsbach family, counts palatinate of Schyren ("Scheyern" in modern German). They ruled for 738 years, from 1180 to 1918. In 1180, however, Styria was also separated from Bavaria. The Electorate of the Palatinate by Rhine (Kurpfalz in German) was also acquired by the House of Wittelsbach in 1214, which they would subsequently hold for six centuries. + +The first of several divisions of the duchy of Bavaria occurred in 1255. With the extinction of the Hohenstaufen in 1268, Swabian territories were acquired by the Wittelsbach dukes. Emperor Louis the Bavarian acquired Brandenburg, Tyrol, Holland and Hainaut for his House but released the Upper Palatinate for the Palatinate branch of the Wittelsbach in 1329. That time also Salzburg finally became independent from the Duchy of Bavaria. + +In the 14th and 15th centuries, upper and lower Bavaria were repeatedly subdivided. Four Duchies existed after the division of 1392: Bavaria-Straubing, Bavaria-Landshut, Bavaria-Ingolstadt and Bavaria-Munich. In 1506 with the Landshut War of Succession, the other parts of Bavaria were reunited, and Munich became the sole capital. The country became a center of the Jesuit-inspired Counter-Reformation. + +Electorate of Bavaria + +In 1623, the Bavarian duke replaced his relative of the Palatinate branch, the Electorate of the Palatinate in the early days of the Thirty Years' War and acquired the powerful prince-elector dignity in the Holy Roman Empire, determining its Emperor thence forward, as well as special legal status under the empire's laws. During the early and mid-18th century the ambitions of the Bavarian prince electors led to several wars with Austria as well as occupations by Austria (War of the Spanish Succession, War of the Austrian Succession with the election of a Wittelsbach emperor instead of a Habsburg). + +To mark the unification of Bavaria and the Electoral Palatinate, both being principal Wittelsbach territories, Maximilian III Joseph, Elector of Bavaria was crowned king of Bavaria. King Maximilian III Joseph was quick to change the coat of arms. The various heraldic symbols were replaced and a classical Wittelsbach pattern introduced. The white and blue lozenges symbolized the unity of the territories within the Bavarian kingdom. + +The new state also comprised the Duchy of Jülich and Berg as these on their part were in personal union with the Palatinate. + +Kingdom of Bavaria + +When Napoleon abolished the Holy Roman Empire, Bavaria became a kingdom in 1806 due, in part, to the Confederation of the Rhine. + +Its area doubled after the Duchy of Jülich was ceded to France, since the Electoral Palatinate was divided between France and the Grand Duchy of Baden. The Duchy of Berg was given to Jerome Bonaparte. The county of Tyrol and the federal state of Salzburg were temporarily reunited with Bavaria but finally ceded to Austria at the Congress of Vienna. + +In return, Bavaria was allowed to annex the modern-day region of Palatinate to the west of the Rhine and Franconia in 1815. Between 1799 and 1817, the leading minister, Count Montgelas, followed a strict policy of modernization copying Napoleonic France; he laid the foundations of centralized administrative structures that survived the monarchy and, in part, have retained core validity through to the 21st century. + +In May 1808, a first constitution was passed by Maximilian I, being modernized in 1818. This second version established a bicameral Parliament with a House of Lords (Kammer der Reichsräte) and a House of Commons (Kammer der Abgeordneten). That constitution was followed until the collapse of the monarchy at the end of World War I. + +After the rise of Prussia in the early 18th century, Bavaria preserved its independence by playing off the rivalry of Prussia and Austria. Allied to Austria, it was defeated along with Austria in the 1866 Austro-Prussian War and was not incorporated into the North German Confederation of 1867, but the question of German unity was still alive. When France declared war on Prussia in 1870, all the south German states (Baden, Württemberg, Hessen-Darmstadt and Bavaria) aside from Austria, joined the Prussian forces and ultimately joined the Federation, which was renamed (German Empire) in 1871. + +Bavaria continued formally as a monarchy, and it had some special rights within the federation (such as an army, railways, postal service and a diplomatic body of its own) but the diplomatic body were later undone by Wilhelm II who declared them illegal and abolished the diplomatic service. + +Part of the German Empire + +When Bavaria became part of the newly formed German Empire, this action was considered controversial by Bavarian nationalists who had wanted to retain independence from the rest of Germany, as had Austria. + +As Bavaria had a heavily Catholic majority population, many people resented being ruled by the mostly Protestant northerners in Prussia. As a direct result of the Bavarian-Prussian feud, political parties formed to encourage Bavaria to break away and regain its independence. + +In the early 20th century, Wassily Kandinsky, Paul Klee, Henrik Ibsen, and other artists were drawn to Bavaria, especially to the Schwabing district in Munich, a center of international artistic activity at the time. + +Free State of Bavaria +Free State has been an adopted designation after the abolition of monarchy in the aftermath of World War I in several German states. + +On 12 November 1918, Ludwig III signed a document, the Anif declaration, releasing both civil and military officers from their oaths; the newly formed republican government, or "People's State" of Socialist premier Kurt Eisner, interpreted this as an abdication. To date, however, no member of the House of Wittelsbach has ever formally declared renunciation of the throne. + +On the other hand, none has ever since officially called upon their Bavarian or Stuart claims. Family members are active in cultural and social life, including the head of the house, Franz, Duke of Bavaria. They step back from any announcements on public affairs, showing approval or disapproval solely by Franz's presence or absence. + +Eisner was assassinated in February 1919, ultimately leading to a Communist revolt and the short-lived Bavarian Soviet Republic being proclaimed 6 April 1919. After violent suppression by elements of the German Army and notably the Freikorps, the Bavarian Soviet Republic fell in May 1919. The Bamberg Constitution () was enacted on 12 or 14 August 1919 and came into force on 15 September 1919 creating the Free State of Bavaria within the Weimar Republic. + +Extremist activity further increased, notably the 1923 Beer Hall Putsch led by the Nazis, and Munich and Nuremberg became seen as strongholds of Nazism during the Weimar Republic and Nazi dictatorship. However, in the crucial German federal election, March 1933, the Nazis received less than 50% of the votes cast in Bavaria. + +As a manufacturing centre, Munich was heavily bombed during World War II and was occupied by United States Armed Forces, becoming a major part of the American Zone of Allied-occupied Germany, which lasted from 1945 to 1947, and then of Bizone. + +The Rhenish Palatinate was detached from Bavaria in 1946 and made part of the new state Rhineland-Palatinate. During the Cold War, Bavaria was part of West Germany. In 1949, the Free State of Bavaria chose not to sign the Founding Treaty (Gründungsvertrag) for the formation of the Federal Republic of Germany, opposing the division of Germany into two countries after World War II. + +The Bavarian Parliament did not sign the Basic Law of Germany, mainly because it was seen as not granting sufficient powers to the individual Länder (states), but at the same time decided that it would still come into force in Bavaria if two-thirds of the other Länder ratified it. +All of the other Länder ratified it, however, so it became law. + +Bavarian identity +Bavarians have often emphasized a separate national identity and considered themselves as "Bavarians" first, "Germans" second. + +In the 19th-century sense, an independent Bavarian State existed from only 1806 to 1871. This feeling started to come about more strongly among Bavarians when the Kingdom of Bavaria was forced by Otto von Bismarck to join the Protestant Prussian-dominated German Empire in 1871, while the Bavarian nationalists wanted to keep Bavaria as Catholic and an independent state. Aside from the minority Bavaria Party, most Bavarians now accept Bavaria is part of Germany. + +Another consideration is that Bavarians foster different cultural identities. Franconia in the north speaks East Franconian German. Bavarian Swabia in the south west speaks Swabian German. Altbayern, the so-called "Old Bavaria", is the regions forming the historic pentagon-shaped Bavaria before the acquisitions through the Vienna Congress. At present the districts of the Upper Palatinate, Lower and Upper Bavaria) speak Austro-Bavarian. + +Flags and coat of arms + +Flags +Uniquely among German states, Bavaria has two official flags of equal status, one with a white and blue stripe, the other with white and blue lozenges. Either may be used by civilians and government offices, who are free to choose between them. Unofficial versions of the flag, especially a lozenge style with coat of arms, are sometimes used by civilians. + +Coat of arms +The modern coat of arms of Bavaria was designed by Eduard Ege in 1946, following heraldic traditions. +The Golden Lion: At the dexter chief, sable, a lion rampant Or, armed and langued gules. This represents the administrative region of Upper Palatinate. +The "Franconian Rake": At the sinister chief, per fess dancetty, gules, and argent. This represents the administrative regions of Upper, Middle and Lower Franconia. +The Blue "Pantier" (mythical creature from French heraldry, sporting a flame instead of a tongue): At the dexter base, argent, a Pantier rampant azure, armed Or and langued gules. This represents the regions of Lower and Upper Bavaria. +The Three Lions: At the sinister base, Or, three lions passant guardant sable, armed and langued gules. This represents Swabia. +The White-And-Blue inescutcheon: The inescutcheon of white and blue fusils askance was originally the coat of arms of the Counts of Bogen, adopted in 1247 by the House of Wittelsbach. The white-and-blue fusils are indisputably the emblem of Bavaria and these arms today symbolize Bavaria as a whole. Along with the People's Crown, it is officially used as the Minor Coat of Arms. +The People's Crown (Volkskrone): The coat of arms is surmounted by a crown with a golden band inset with precious stones and decorated with five ornamental leaves. This crown first appeared in the coat of arms to symbolize sovereignty of the people after the royal crown was eschewed in 1923. + +Geography + +Bavaria shares international borders with Austria (Salzburg, Tyrol, Upper Austria and Vorarlberg) and the Czech Republic (Karlovy Vary, Plzeň and South Bohemian Regions), as well as with Switzerland (across Lake Constance to the Canton of St. Gallen). + +Neighboring states within Germany are Baden-Württemberg, Hesse, Thuringia, and Saxony. Two major rivers flow through the state: the Danube (Donau) and the Main. The Bavarian Forest and the Bohemian Forest form the vast majority of the frontier with the Czech Republic and Bohemia. + +The geographic center of the European Union is located in the northwestern corner of Bavaria. + +Climate +At lower elevations the climate is classified according to Köppen's guide as "Cfb" or "Dfb". At higher altitudes the climate becomes "Dfc" and "ET". + +The summer months have been getting hotter in recent years. For example, June 2019 was the warmest June in Bavaria since weather observations have been recorded and the winter 2019/2020 was 3 degrees Celsius warmer than the average temperature for many years all over Bavaria. On 20 December 2019 a record temperature of was recorded in Piding. In general winter months are seeing more precipitation which is taking the form of rain more often than that of snow compared to the past. Extreme weather like the 2013 European floods or the 2019 European heavy snowfalls is occurring more and more often. One effect of the continuing warming is the melting of almost all Bavarian Alpine glaciers: Of the five glaciers of Bavaria only the Höllentalferner is predicted to exist over a longer time perspective. The Südliche Schneeferner has almost vanished since the 1980s. + +Administrative divisions + +Administrative regions + +Bavaria is divided into seven administrative regions called (singular ).

In the other larger states of Germany, there are only as administrative divisions and no self-governing entities at the level of the as the in Bavaria. + +Population and area + +Districts + +The second communal layer is made up of 71 rural districts (called , singular ) that are comparable to counties, as well as the 25 independent cities (, singular ), both of which share the same administrative responsibilities. + +Rural districts: + +Independent cities: + +Municipalities + +The 71 rural districts are on the lowest level divided into 2,031 regular municipalities (called , singular ). Together with the 25 independent cities (, which are in effect municipalities independent of administrations), there are a total of 2,056 municipalities in Bavaria. + +In 44 of the 71 rural districts, there are a total of 215 unincorporated areas (as of 1 January 2005, called , singular ), not belonging to any municipality, all uninhabited, mostly forested areas, but also four lakes (-without islands, -without island , , which are the three largest lakes of Bavaria, and ). + +Major cities and towns + +Source: Bayerisches Landesamt für Statistik und Datenverarbeitung + +Politics + +Bavaria has a multiparty system dominated by the conservative Christian Social Union (CSU), which has won every election since 1945 with the exception of the 1950 ballot. Other important parties are The Greens, which became the second biggest political party in the 2018 local parliament elections and the center-left Social Democrats (SPD), who have dominated the city of Munich until 2020. Hitherto, Wilhelm Hoegner has been the only SPD candidate to ever become Minister-President; notable successors in office include multi-term Federal Minister Franz Josef Strauss, a key figure among West German conservatives during the Cold War years, and Edmund Stoiber, who both failed with their bids for Chancellorship. + +The German Greens and the center-right Free Voters have been represented in the state parliament since 1986 and 2008 respectively. + +In the 2003 elections the CSU won a ⅔ supermajority – something no party had ever achieved in postwar Germany. However, in the subsequent 2008 elections the CSU lost the absolute majority for the first time in 46 years. + +The losses were partly attributed by some to the CSU's stance for an anti-smoking bill. (A first anti-smoking law had been proposed by the CSU and passed but was watered down after the election, after which a referendum enforced a strict antismoking bill with a large majority). + +Current Landtag + +The last state elections were held on 14 October 2018 in which the CSU lost its absolute majority in the state parliament in part due to the party's stances as part of the federal government, winning 37.2% of the vote; the party's second worst local election outcome in its history after 1950. The Greens who had surged in the polls leading up to the election have replaced the social-democratic SPD as the second biggest force in the Landtag with 17.6% of the vote. The SPD lost over half of its previous share compared to 2013 with a mere 9.7% in 2018. The liberals of the FDP were again able to reach the five-percent-threshold in order to receive mandates in parliament after they were not part of the Landtag after the 2013 elections. Also entering the new parliament were the right-wing populist Alternative for Germany (AfD), with 10.2% of the vote. + +The center-right Free Voters party gained 11.6% of the vote and formed a government coalition with the CSU which led to the subsequent reelection of Markus Söder as Minister-President of Bavaria. + +Government +Bavarian Cabinet since 12 November 2018 +The Constitution of Bavaria of the Free State of Bavaria was enacted on 8 December 1946. The new Bavarian Constitution became the basis for the Bavarian State after the Second World War. + +Bavaria has a unicameral (English: State Parliament), elected by universal suffrage. Until December 1999, there was also a , or Senate, whose members were chosen by social and economic groups in Bavaria, but following a referendum in 1998, this institution was abolished. + +The Bavarian State Government consists of the Minister-President of Bavaria, eleven Ministers and six Secretaries of State. The Minister-President is elected for a period of five years by the State Parliament and is head of state. With the approval of the State Parliament he appoints the members of the State Government. The State Government is composed of the: + +State Chancellery () +Ministry of the Interior, for Sport and Integration () +Ministry for Housing, Construction and Transport () +Ministry of Justice () +Ministry for Education and Culture () +Ministry for Science and Art () +Ministry of Finance and for Home Affairs () +Ministry for Economic Affairs, Regional Development and Energy () +Ministry for Environment and Consumer Protection () +Ministry for Food, Agriculture and Forestry () +Ministry for Family, Labour and Social Affairs () +Ministry for Health and Care () +Ministry for Digital Affairs () + +Political processes also take place in the seven regions ( or ) in Bavaria, in the 71 rural districts () and the 25 towns and cities forming their own districts (), and in the 2,031 local authorities (). + +In 1995 Bavaria introduced direct democracy on the local level in a referendum. This was initiated bottom-up by an association called Mehr Demokratie (English: More Democracy). This is a grass-roots organization which campaigns for the right to citizen-initiated referendums. In 1997 the Bavarian Supreme Court tightened the regulations considerably (including by introducing a turn-out quorum). Nevertheless, Bavaria has the most advanced regulations on local direct democracy in Germany. This has led to a spirited citizens' participation in communal and municipal affairs—835 referendums took place from 1995 through 2005. + +Minister-presidents of Bavaria since 1945 + +Designation as a "free state" +Unlike most German states (Länder), which simply designate themselves as "State of" (Land [...]), Bavaria uses the style of "Free State of Bavaria" (Freistaat Bayern). The difference from other states is purely terminological, as German constitutional law does not draw a distinction between "States" and "Free States". The situation is thus analogous to the United States, where some states use the style "Commonwealth" rather than "State". The term "Free State", a creation of the 19th century and intended to be a German alternative to (or translation of) the Latin-derived republic, was common among the states of the Weimar Republic, after German monarchies had been abolished. Unlike most other states – many of which were new creations – Bavaria has resumed this terminology after World War II. Two other states, Saxony and Thuringia, also call themselves "Free State". + +Arbitrary arrest and human rights +In July 2017, Bavaria's parliament enacted a new revision of the "Gefährdergesetz", allowing the authorities to imprison a person for a three months term, renewable indefinitely, when they have not committed a crime but it is assumed that they might commit a crime "in the near future". Critics like the prominent journalist Heribert Prantl have called the law "shameful" and compared it to Guantanamo Bay detention camp, assessed it to be in violation of the European Convention on Human Rights, and also compared it to the legal situation in Russia, where a similar law allows for imprisonment for a maximum term of two years (i.e., not indefinitely). + +Economy + +Bavaria has long had one of the largest economies of any region in Germany, and in Europe. Its gross domestic product (GDP) in 2007 exceeded €434 billion (about U.S. $600 billion). This makes Bavaria itself one of the largest economies in Europe, and only 20 countries in the world have a higher GDP. The GDP of the region increased to €617.1 billion in 2018, accounting for 18.5% of German economic output. GDP per capita adjusted for purchasing power was €43,500 or 145% of the EU27 average in the same year. The GDP per employee was 114% of the EU average. This makes Bavaria one of the wealthiest regions in Europe. Bavaria has strong economic ties with Austria, Czech Republic, Switzerland, and Northern Italy. +In 2019 GDP was €832.4 ($905.7) billion, €48,323 ($52,577.3) per capita. + +Agriculture + +The most distinctive high points of Bavarian agriculture are: +Hop growing in region Hallertau, which is up to 80% of German production and exported worldwide. +Inland aquaculture of carps and trout. +The well-hydrated alpine meadows are used to produce large quantities of quality milk, which is used to make a variety of cheese (including blue-veined cheese), yogurt and butter. +The cultivation of asparagus is widespread, which is a very popular new season vegetable. In season ("Spargelzeit") restaurants offer special separated asparagus menu. There is an asparagus museum in Schrobenhausen. +There are farms producing venison from deer and roe. +Viticulture is widespread in Lower Franconia. +Good ecology and strict control allow produce a large amount of organic products ("bio") and baby food. + +Industries + +Bavaria has the best developed industry in Germany and the lowest unemployment rate with 2.9% as of October 2021. + +Branches: +Oil refining. Although there is oil production in Bavaria, it does not meet domestic needs. Most of the oil is imported via pipelines from the Czech Republic (Russian oil) and from the Italian port of Trieste (Near East oil). Three refineries are situated near Ingolstadt and another one in Burghausen. Last one is a part of Bavarian chemical triangle and delivery row materials to other chemical plants. + +Automotive is the most important and best developed Bavarian industry, which includes manufacture of luxury cars (4 BMW and 2 Audi plants, R&D centers, test tracks), trucks (Traton MAN), special vehicles (Tadano Faun), buses (Evobus/Setra) and automotive parts (engines, electronics, cables, seats, interiors, cabrio roofs, heating and brake systems, software). Bavaria has the second-most employees (207,829) in the automotive industry of all German states after Baden-Württemberg as of 2018. + +Aerospace and defense, which manufacture multi-role attack jet Eurofighter Typhoon, missiles from MBDA and Diehl Defence, parts of rocket Ariane, regional jet Dornier 728, ultra-light planes from Grob Aerospace, turbo jet engines for civil and military applications from MTU Aero Engines, helicopters Airbus, main battle tank Leopard 2, drones, composite parts, avionics, radars, propellants, initiators, powder, munitions. In Munich suburban Oberpfaffenhofen situated control center of European satellite navigation system Galileo, German Space Operations Center, Microwaves and Radar Institute, Institute of Communications and Navigation, Remote Sensing Technology Institute, Institute of Atmospheric Physics, Institute of Robotics and Mechatronics, Institute for Software Technology, Institute of System Dynamics and Control. + +Other transport manufacturing are represented in Bavaria. Ship yards even exist, for example Bavaria Yachtbau, despite being located many hundreds of kilometers from the sea, manufacturing 4-stroke marine diesel engines which are used in cruise liners, ferries and warships. Rail technology is produced in Munich-Allach (locomotive Siemens Vectron) and rail maintenance vehicles in Freilassing. + +Electronics. Chip design centers situated in Munich area (Infineon, Intel, Apple). There are 3 FABs: Infineon in Regensburg, Texas Instruments in Freising and Osram Optosemiconductors also in Regensburg. Power semiconductors are manufactured by Semikron. CNC controls are produced by Heidenhain, Traunreut and Siemens, Amberg. Silicon wafer for electronic manufacturing are delivered from Siltronic plant in Burghausen. + +Medical equipment. In Erlangen is a headquarters of Siemens Healthineers which produce devices for computer tomography, interventional X-ray systems, radiation therapy, molecular and magnetic resonance imaging, software. Brainlab creates software and hardware for image-guided surgery. Roche Diagnostics in Penzberg manufactures therapeutic proteins, diagnostic tests, reagents, analyze system and biopharma products. + +Brewery. Bavaria has long tradition of brewery, near a half of all German breweries are located here (645 of 1300). All possible types of breweries exist: home brewery of hotel or restaurant, belong to big international concern, state-owned, castle or monastery breweries. The perfect quality of beer is guaranteed by 500-years law ("Reinheitsgebot"), which allow as beer ingredients only water, hops, yeast and malt of barley, wheat or rye. But difference of roasting, fermentation or mixing allow to produce many different types of beers (not brand). Vladimir Putin at 2009 tasted beer from Brauerei Aying, Barack Obama at 2015 also tasted Bavarian beer of Karg Brauerei in Murnau. In Freising situated research center Weihenstephan for brewing and food quality. + +Companies +Many large companies are headquartered in Bavaria, including Adidas, Allianz, Audi, BMW, Brose, BSH Hausgeräte, HypoVereinsbank, Infineon, KUKA, Traton, MTU Aero Engines, Munich Re, Osram, Puma, Rohde & Schwarz, Schaeffler, Siemens, Wacker Chemie, Linde, Vitesco Technologies, Webasto, Grob, Heidenhain, Koenig & Bauer, Kaeser Compressors, Krones, Knorr-Bremse, Wacker Neuson, Krauss-Maffei Wegmann, Siltronic, Leoni, Fielmann, MediaMarkt, Conrad Electronic, BayWa, ProSiebenSat.1 Media, Telefónica Germany, Knauf, Rehau, and Giesecke+Devrient. + +Also American companies open a lot of research and development centers in Munich region: Apple (chip design), Google (data security), IBM (Watson technology), Intel (drones and telecommunication chips), General Electric (3D-printers and additive manufacturing), Gleason (gears manufacturing), Texas Instruments (chip design and manufacturing), Coherent (lasers). + +Tourism +With 40 million tourists in 2019, Bavaria is the most visited German state and one of Europe's leading tourist destinations. + +Attractions include: +Amusement parks: Legoland in Günzburg, Bayern-Park in Reisbach (Vils), Playmobil in Zirndorf, Skyline Park in Bad Wörishofen and Bavaria Filmstadt in Grünwald +Christmas markets in Rothenburg ob der Tauber, Nuremberg and Munich +Factory Outlet Centers: Ingolstadt Village and Wertheim Village +Festivals: Oktoberfest, Nürnberger Frühlingsfest and Nürnberger Herbstfest +Museums and castles: Deutsches Museum, Alte Pinakothek, Lenbachhaus, Bavarian National Museum in Munich, Germanisches Nationalmuseum in Nuremberg, Margravial Opera House in Bayreuth, Maximilianmuseum Augsburg + +Unemployment +The unemployment rate stood at 2.6% in October 2018, the lowest in Germany and one of the lowest in the European Union. + +Demographics + +Bavaria has a population of approximately 13.1 million inhabitants (2020). Eight of the 80 largest cities in Germany are located within Bavaria with Munich being the largest (1,484,226 inhabitants, approximately 6.1 million when including the broader metropolitan area), followed by Nuremberg (518,370 inhabitants, approximately 3.6 million when including the broader metropolitan area), Augsburg (296,582 inhabitants) and Regensburg (153,094 inhabitants). All other cities in Bavaria had less than 150,000 inhabitants each in 2020. Population density in Bavaria was , below the national average of . Foreign nationals resident in Bavaria (both immigrants and refugees/asylum seekers) were principally from other EU countries and Turkey. + +Vital statistics + +Culture +Some features of the Bavarian culture and mentality are remarkably distinct from the rest of Germany. Noteworthy differences (especially in rural areas, less significant in the major cities) can be found with respect to religion, traditions, and language. + +Religion + +Bavarian culture (Altbayern) has a long and predominant tradition of Roman Catholic faith. Pope Benedict XVI (Joseph Alois Ratzinger) was born in Marktl am Inn in Upper Bavaria and was Cardinal-Archbishop of Munich and Freising. Otherwise, the culturally Franconian and Swabian regions of the modern State of Bavaria are historically more diverse in religiosity, with both Catholic and Protestant traditions. In 1925, 70.0% of the Bavarian population was Catholic, 28.8% was Protestant, 0.7% was Jewish, and 0.5% was placed in other religious categories. + + 46.9% of Bavarians adhered to Catholicism (a decline from 70.4% in 1970). 17.2 percent of the population adheres to the Evangelical Lutheran Church in Bavaria, which has also declined since 1970. Three percent was Orthodox, Muslims make up 4.0% of the population of Bavaria. 31.9 percent of Bavarians are irreligious or adhere to other religions. + +Traditions +Bavarians commonly emphasize pride in their traditions. Traditional costumes collectively known as Tracht are worn on special occasions and include in Altbayern Lederhosen for males and Dirndl for females. Centuries-old folk music is performed. The Maibaum, or Maypole (which in the Middle Ages served as the community's business directory, as figures on the pole represented the trades of the village), and the bagpipes of the Upper Palatinate region bear witness to the ancient Celtic and Germanic remnants of cultural heritage of the region. There are many traditional Bavarian sports disciplines, e.g. the Aperschnalzen, competitive whipcracking. + +Whether in Bavaria, overseas or with citizens from other nations Bavarians continue to cultivate their traditions. They hold festivals and dances to keep their heritage alive. + +Food and drink + +Bavarians tend to place a great value on food and drink. In addition to their renowned dishes, Bavarians also consume many items of food and drink which are unusual elsewhere in Germany; for example ("white sausage") or in some instances a variety of entrails. At folk festivals and in many beer gardens, beer is traditionally served by the litre (in a ). Bavarians are particularly proud of the traditional , or beer purity law, initially established by the Duke of Bavaria for the City of Munich (i.e. the court) in 1487 and the duchy in 1516. According to this law, only three ingredients were allowed in beer: water, barley, and hops. In 1906 the made its way to all-German law, and remained a law in Germany until the EU partly struck it down in 1987 as incompatible with the European common market. German breweries, however, cling to the principle, and Bavarian breweries still comply with it in order to distinguish their beer brands. Bavarians are also known as some of the world's most prolific beer drinkers, with an average annual consumption of 170 liters per person. + +Bavaria is also home to the Franconia wine region, which is situated along the river Main in Franconia. The region has produced wine (Frankenwein) for over 1,000 years and is famous for its use of the Bocksbeutel wine bottle. The production of wine forms an integral part of the regional culture, and many of its villages and cities hold their own wine festivals (Weinfeste) throughout the year. + +Language and dialects + +Three German dialects are most commonly spoken in Bavaria: Austro-Bavarian in Old Bavaria (Upper Bavaria, Lower Bavaria, and the Upper Palatinate), Swabian German (an Alemannic German dialect) in the Bavarian part of Swabia (southwest) and East Franconian German in Franconia (north). In the small town Ludwigsstadt in the north, district Kronach in Upper Franconia, Thuringian dialect is spoken. During the 20th century an increasing part of the population began to speak Standard German (Hochdeutsch), mainly in the cities. + +Ethnography +Bavarians consider themselves to be egalitarian and informal. Their sociability can be experienced at the annual Oktoberfest, the world's largest beer festival, which welcomes around six million visitors every year, or in the famous beer gardens. In traditional Bavarian beer gardens, patrons may bring their own food but buy beer only from the brewery that runs the beer garden. + +Museums +There are around 1,300 museums in Bavaria, including museums of art and cultural history, castles and palaces, archaeological and natural history collections, museums of technological and industrial history, and farm and open-air museums. The history of Bavarian museums dates back to manorial cabinets of curiosities and treasuries. The art holdings of the House of Wittelsbach thus formed the first and essential foundation of later state museums. As early as the mid-16th century, Duke Albrecht V (r. 1550-1579) had collected paintings as well as Greek and Roman sculptures (or copies made of them). He had the Antiquarium in the Munich Residence built specifically for his collection of antique sculptures. The electors Maximilian I (r. 1594-1651) and Max II. Emanuel (r. 1679-1726) expanded the art collections considerably. In the Age of Enlightenment at the end of the 18th century, there was a demand to open up art collections to the general public in the spirit of "popular education". But Museums were not founded by the state until the time of the art-loving King Ludwig I (r. 1825-1848). In Munich, he built Glyptothek (opened 1830), Alte Pinakothek (opened 1836), and Neue Pinakothek (opened 1853). Also, the foundation of the Germanisches Nationalmuseum in Nuremberg (1852), the establishment of the Neue Pinakothek, which opened in 1853, and the Bavarian National Museum (1867) in Munich were of central importance for the development of museums in Bavaria in the 19th century. With the end of the monarchy in 1918, many castles and formerly Wittelsbach property passed to the young Free State. In particular, the castles of king Ludwig II (r. 1864-1886) Neuschwanstein, Linderhof and Herrenchiemsee, quickly became magnets for the public. Since then, the number oif Bavarian Museums has grown considerably, from 125 in 1907 to around 1,300 today. + +Sports + +Football +Bavaria is home to several football clubs including FC Bayern Munich, 1. FC Nürnberg, FC Augsburg, TSV 1860 Munich, FC Ingolstadt 04 and SpVgg Greuther Fürth. Bayern Munich is the most successful football team in Germany having won a record 32 German titles and 6 UEFA Champions League titles. They are followed by 1. FC Nürnberg who have won 9 titles. SpVgg Greuther Fürth have won 3 championships while TSV 1860 Munich have been champions once. + +Basketball +Bavaria is also home to four professional basketball teams, including FC Bayern Munich, Brose Baskets Bamberg, s.Oliver Würzburg, Nürnberg Falcons BC, and TSV Oberhaching Tropics. + +Ice hockey +There are five Bavarian ice hockey teams playing in the German top-tier league DEL: EHC Red Bull München, Nürnberg Ice Tigers, Augsburger Panther, ERC Ingolstadt, and Straubing Tigers. + +Notable people +Notable people who have lived, or live currently, in Bavaria include: + +Kings: Arnulf of Carinthia, Carloman of Bavaria, Charles the Fat, Lothair I, Louis the Child, Louis the German, Louis the Younger, Ludwig I of Bavaria, Ludwig II of Bavaria, Ludwig III of Bavaria, Maximilian I Joseph of Bavaria, Maximilian II of Bavaria, Otto, King of Bavaria +Religious leaders: Pope Benedict XVI (Joseph Aloisius Ratzinger); Pope Damasus II, Pope Victor II +Painters: Albrecht Dürer, Albrecht Altdorfer, Joseph Karl Stieler, Carl Spitzweg, Erwin Eisch, Franz von Lenbach, Franz von Stuck, Franz Marc, Gabriele Münter, Hans Holbein the Elder, Johann Christian Reinhart, Lucas Cranach, Paul Klee +Classical musicians: Orlando di Lasso, Christoph Willibald Gluck, Leopold Mozart, Max Reger, Richard Wagner, Richard Strauss, Carl Orff, Johann Pachelbel, Theobald Boehm, Klaus Nomi +Other musicians: Hans-Jürgen Buchner, Barbara Dennerlein, Klaus Doldinger, Franzl Lang, Bands: Spider Murphy Gang, Sportfreunde Stiller, Obscura, Michael Bredl +Opera singers: Jonas Kaufmann, Diana Damrau +Writers, poets and playwrights: Hans Sachs, Jean Paul, Friedrich Rückert, August von Platen-Hallermünde, Frank Wedekind, Christian Morgenstern, Oskar Maria Graf, Bertolt Brecht, Lion Feuchtwanger, Thomas Mann, Klaus Mann, Golo Mann, Ludwig Thoma, Michael Ende, Ludwig Aurbacher +Scientists: Max Planck, Wilhelm Conrad Röntgen, Werner Heisenberg, Adam Ries, Joseph von Fraunhofer, Georg Ohm, Johannes Stark, Carl von Linde, Ludwig Prandtl, Rudolf Mössbauer, Lothar Rohde, Hermann Schwarz, Robert Huber, Martin Behaim, Levi Strauss, Rudolf Diesel, Feodor Lynen, Georges J.

With an area of 29,480 square kilometres (11,382 square miles) and a population of 2.5 million residents, it is the fifth-largest German state by area and the tenth-most populous. Potsdam is the state capital and largest city, and other major towns are Cottbus, Brandenburg an der Havel and Frankfurt (Oder). + +Brandenburg surrounds the national capital and city-state of Berlin, and together they form the Berlin/Brandenburg Metropolitan Region, the third-largest metropolitan area in Germany with a total population of about 6.2 million. There was an unsuccessful attempt to unify both states in 1996 and the states cooperate on many matters to this day. + +Brandenburg originated in the Northern March in the 900s AD, from areas conquered from the Wends. It later became the Margraviate of Brandenburg, a major principality of the Holy Roman Empire. In the 15th century, it came under the rule of the House of Hohenzollern, which later also became the ruling house of the Duchy of Prussia and established Brandenburg-Prussia, the core of the later Kingdom of Prussia. From 1815 to 1947, Brandenburg was a province of Prussia. + +Following the abolition of Prussia after World War II, Brandenburg was established as a state by the Soviet Military Administration in Germany, and became a state of the German Democratic Republic in 1949. In 1952, the state was dissolved and broken up into multiple regional districts. Following German reunification, Brandenburg was re-established in 1990 and became one of the five new states of the Federal Republic of Germany. + +The origin of the name Brandenburg is believed to be West Slavic , meaning 'war forest'. + +History + +In late medieval and early modern times, Brandenburg was one of seven electoral states of the Holy Roman Empire, and, along with Prussia, formed the original core of the German Empire, the first unified German state. Governed by the Hohenzollern dynasty from 1415, it contained the future German capital Berlin. After 1618 the Margraviate of Brandenburg and the Duchy of Prussia were combined to form Brandenburg-Prussia, which was ruled by the same branch of the House of Hohenzollern. In 1701 the state was elevated as the Kingdom of Prussia. Franconian Nuremberg and Ansbach, Swabian Hohenzollern, the eastern European connections of Berlin, and the status of Brandenburg's ruler as prince-elector together were instrumental in the rise of that state. + +Early Middle Ages + +Brandenburg is situated in territory known in antiquity as Magna Germania, which reached to the Vistula river. By the 7th century, Slavic peoples are believed to have settled in the Brandenburg area. The Slavs expanded from the east, possibly driven from their homelands in present-day Ukraine and perhaps Belarus by the invasions of the Huns and Avars. They relied heavily on river transport. The two principal Slavic groups in the present-day area of Brandenburg were the Hevelli in the west and the Sprevane in the east. + +Beginning in the early 10th century, Henry the Fowler and his successors conquered territory up to the Oder River. Slavic settlements such as Brenna (Brandenburg an der Havel), Budusin (Bautzen), and Chośebuz (Cottbus) came under imperial control through the installation of margraves. Their main function was to defend and protect the eastern marches. In 948 Emperor Otto I established margraves to exert imperial control over the pagan Slavs west of the Oder River. Otto founded the Bishoprics of Brandenburg and Havelberg. The Northern March was founded as a northeastern border territory of the Holy Roman Empire. However, a great uprising of Wends drove imperial forces from the territory of present-day Brandenburg in 983. The region returned to the control of Slavic leaders. + +Late Middle Ages + +During the 12th century, the German kings and emperors re-established control over the mixed Slav-inhabited lands of present-day Brandenburg, although some Slavs like the Sorbs in Lusatia adapted to Germanization while retaining their distinctiveness. The Roman Catholic Church brought bishoprics which, with their walled towns, afforded protection from attacks for the townspeople. With the monks and bishops, the history of the town of Brandenburg an der Havel, which was the first center of the state of Brandenburg, began. + +In 1134, in the wake of a German crusade against the Wends, the German magnate, Albert the Bear, was granted the Northern March by the Emperor Lothar III. He formally inherited the town of Brandenburg and the lands of the Hevelli from their last Wendish ruler, Pribislav, in 1150. After crushing a force of Sprevane who occupied the town of Brandenburg in the 1150s, Albert proclaimed himself ruler of the new Margraviate of Brandenburg. Albert, and his descendants the Ascanians, then made considerable progress in conquering, colonizing, Christianizing, and cultivating lands as far east as the Oder. Within this region, Slavic and German residents intermarried. During the 13th century, the Ascanians began acquiring territory east of the Oder, later known as the Neumark (see also Altmark). + +In 1320, the Brandenburg Ascanian line came to an end, and from 1323 up until 1415 Brandenburg was under the control of the Wittelsbachs of Bavaria, followed by the Luxembourg Dynasties. Under the Luxembourgs, the Margrave of Brandenburg gained the status of a prince-elector of the Holy Roman Empire. In the period 1373–1415, Brandenburg was a part of the Bohemian Crown. In 1415, the Electorate of Brandenburg was granted by Emperor Sigismund to the House of Hohenzollern, which would rule until the end of World War I. The Hohenzollerns established their capital in Berlin, by then the economic center of Brandenburg. + +16th and 17th centuries + +Brandenburg converted to Protestantism in 1539 in the wake of the Protestant Reformation, and generally did quite well in the 16th century, with the expansion of trade along the Elbe, Havel, and Spree rivers. The Hohenzollerns expanded their territory by co-rulership since 1577 and acquiring the Duchy of Prussia in 1618, the Duchy of Cleves (1614) in the Rhineland, and territories in Westphalia. The result was a sprawling, disconnected country known as Brandenburg-Prussia that was in poor shape to defend itself during the Thirty Years' War. + +Beginning near the end of that devastating conflict, however, Brandenburg enjoyed a string of talented rulers who expanded their territory and power in Europe. The first of these was Frederick William, the so-called "Great Elector", who worked tirelessly to rebuild and consolidate the nation. He moved the royal residence to Potsdam. At the Peace of Westphalia, his envoy Joachim Friedrich von Blumenthal negotiated the acquisition of several important territories such as Halberstadt. Under the Treaty of Oliva Christoph Caspar von Blumenthal (son of the above) negotiated the incorporation of the Duchy of Prussia into the Hohenzollern inheritance. + +Kingdom of Prussia and German Empire + +When Frederick William died in 1688, he was followed by his son Frederick, third of that name in Brandenburg. As the lands that had been acquired in Prussia were outside the boundaries of the Holy Roman Empire, Frederick assumed (as Frederick I) the title of "King in Prussia" (1701). Although his self-promotion from margrave to king relied on his title to the Duchy of Prussia, Brandenburg was still the most important portion of the kingdom. However, this combined state is known as the Kingdom of Prussia. + +Brandenburg remained the core of the Kingdom of Prussia, and it was the site of the kingdom's capitals, Berlin and Potsdam. When Prussia was subdivided into provinces in 1815, the territory of the Margraviate of Brandenburg became the Province of Brandenburg, again subdivided into the government region of Frankfurt and Potsdam. In 1881, the City of Berlin was separated from the Province of Brandenburg. However, industrial towns ringing Berlin lay within Brandenburg, and the growth of the region's industrial economy brought an increase in the population of the province. The Province of Brandenburg had an area of and a population of 2.6 million (1925). After Germany's defeat in World War II, the Neumark, the part of Brandenburg east of the Oder–Neisse line, even absent any Polish-speaking population in this area, became part of Poland. The entire population of former East Brandenburg was expelled en masse. The remainder of the province became a state in the Soviet Zone of occupation in Germany when Prussia was dissolved in 1947. + +East Germany + +After the foundation of East Germany in 1949, Brandenburg formed one of its component states. The State of Brandenburg was completely dissolved in 1952 by the Socialist government of East Germany, doing away with all component states. The East German government then divided Brandenburg among several Bezirke or districts. (See Administrative division of the German Democratic Republic). Most of Brandenburg lay within the Bezirke of Cottbus, Frankfurt, or Potsdam, but parts of the former province passed to the Schwerin, Neubrandenburg and Magdeburg districts (town Havelberg). East Germany relied heavily on lignite (the lowest grade of coal) as an energy source, and lignite strip mines marred areas of south-eastern Brandenburg. The industrial towns surrounding Berlin were important to the East German economy, while rural Brandenburg remained mainly agricultural. + +Federal Republic of Germany +The present State of Brandenburg was re-established on 3 October 1990 upon German reunification. The newly elected Landtag of Brandenburg first met on 26 October 1990. As in other former parts of East Germany, the lack of modern infrastructure and exposure to West Germany's competitive market economy brought widespread unemployment and economic difficulty. In the recent years, however, Brandenburg's infrastructure has been modernized and unemployment has slowly declined. + +Berlin-Brandenburg fusion attempt + +The legal basis for a combined state of Berlin and Brandenburg is different from other state fusion proposals. Normally, Article 29 of the Basic Law stipulates that states may only merge after a specific federal Act of Parliament is enacted. However, a clause added to the Basic Law in 1994, Article 118a, allows Berlin and Brandenburg to unify without federal approval, requiring a referendum and a ratification by both state parliaments. + +In 1996, an attempt of unifying the states of Berlin and Brandenburg was rejected at referendum. Both share a common history, dialect and culture and in 2020, over 225,000 residents of Brandenburg commute to Berlin. The fusion had the near-unanimous support by a broad coalition of both state governments, political parties, media, business associations, trade unions and churches. Though Berlin voted in favor by a small margin, largely based on support in former West Berlin, Brandenburg voters disapproved of the fusion by a large margin. It failed largely due to Brandenburg voters not wanting to take on Berlin's large and growing public debt and fearing losing identity and influence to the capital. + +Geography + +Brandenburg is bordered by Mecklenburg-Vorpommern in the north, Poland in the east, the Freistaat Sachsen in the south, Saxony-Anhalt in the west, and Lower Saxony in the northwest. + +The Oder river forms a part of the eastern border, the Elbe river a portion of the western border. The main rivers in the state itself are the Spree and the Havel. In the southeast, there is a wetlands region called the Spreewald; it is the northernmost part of Lusatia, where the Sorbs, a Slavic people, still live. These areas are bilingual, i.e., German and Sorbian are both used. + +Protected areas +Brandenburg is known for its well-preserved natural environment and its ambitious natural protection policies which began in the 1990s. 15 large protected areas were designated following Germany's reunification. Each of them is provided with state-financed administration and a park ranger staff, who guide visitors and work to ensure nature conservation. Most protected areas have visitor centers. + +National parks +Lower Oder Valley National Park (106 km2) + +Biosphere reserves + +Spreewald Biosphere Reserve () +Schorfheide-Chorin Biosphere Reserve () +River Landscape Elbe-Brandenburg Biosphere Reserve () + +Nature parks + Barnim Nature Park () + Dahme-Heideseen Nature Park () + High Fläming Nature Park () + Märkische Schweiz Nature Park () + Niederlausitzer Heidelandschaft Nature Park () + Niederlausitzer Landrücken Nature Park () + Nuthe-Nieplitz Nature Park () + Schlaube Valley Nature Parke () + Uckermark Lakes Nature Park () + Westhavelland Nature Park () + Stechlin-Ruppiner Land Nature Park () + +Demographics + +Brandenburg has the second lowest population density among the German states, after Mecklenburg-Vorpommern. + +Development + +Religion + +17.1% of the Brandenburgers are registered members of the local, regional Protestant church (mostly the Evangelical Church in Berlin, Brandenburg and Silesian Upper Lusatia), while 3.1% are registered with the Roman Catholic Church (mostly the Archdiocese of Berlin, and a minority in the Diocese of Görlitz). The majority (79.8%) of Brandenburgers, whether of Christian or other beliefs, choose not to register with the government as members of these churches, and therefore do not pay the church tax. + +Foreign population + +Politics + +Politically, Brandenburg is a stronghold of the Social Democratic Party, which won the largest share of the vote and seats in every state election. All three Minister-Presidents of Brandenburg have come from the Social Democratic Party (unlike any other state except Bremen) and they even won an absolute majority of seats and every single-member constituency in the 1994 state election. + +On a federal level, the Social Democratic Party has also been the strongest party in most federal elections, their strongholds being the northwestern part of the state and Potsdam and its surrounding areas. However, the Christian Democratic Union won the most votes in 1990, their 2013 landslide and in 2017. In 2009, The Left won the most votes in a year where, like in 2017, the Social Democratic collapsed. Prominent politicians from Brandenburg include Social Democrats Frank-Walter Steinmeier, who served in the Bundestag for Brandenburg before being elected President of Germany, and likely Chancellor of Germany Olaf Scholz, who sits in the Bundestag for Potsdam. + +Like in all other New states of Germany, the populist parties The Left and, more recently, the Alternative for Germany are especially strong in Brandenburg. + +Brandenburg has 4 out of 69 votes in the Bundesrat and, as of 2021, 25 seats out of 736 in the Bundestag. + +Subdivisions + +Brandenburg is divided into 14 rural districts (Landkreise) and four urban districts (kreisfreie Städte), shown with their population in 2011: + +Government + +The most recent election took place on 1 September 2019. A coalition government was formed by the Social Democrats, The Greens, and the Christian Democratic Union led by incumbent Minister-President Dietmar Woidke (SPD), replacing the previous coalition between the Social Democrats and The Left. The next ordinary state election will likely occur in autumn 2024. + +Economy +The Gross domestic product (GDP) of the state was 72.9 billion euros in 2018, accounting for 2.2% of German economic output. GDP per capita adjusted for purchasing power was 26,700 euros or 88% of the EU27 average in the same year. The GDP per employee was 91% of the EU average. The GDP per capita was the third lowest of all states in Germany. + +The unemployment rate stood at 5.6% in November 2022 and was higher than the German average but lower than the average of Eastern Germany. + +Transport +Berlin Schönefeld Airport (IATA code: SXF) was the largest airport in Brandenburg. It was the second largest international airport of the Berlin-Brandenburg metropolitan region and was located southeast of central Berlin in Schönefeld. The airport was a base for Condor, easyJet and Ryanair. In 2016, Schönefeld handled 11,652,922 passengers (an increase of 36.7%). + +It was planned to incorporate Schönefeld's existing infrastructure and terminals into the new Berlin Brandenburg Airport (BER), which was not scheduled to open before the end of 2020. The new BER will have an initial capacity of 35–40 million passengers a year. Due to increasing air traffic in Berlin and Brandenburg, plans for airport expansions were in the making, as of 2017. + +BER airport is now open and receives over sixty combined passenger, charter and cargo airlines. + +Education and research + +Higher education + +In 2016, around 49,000 students were enrolled in Brandenburg universities and higher education facilities. The largest institution is the University of Potsdam, located southwest of Berlin. In 2019 the state of Brandenburg adopted an Open Access strategy calling on universities to develop transformation strategies to make knowledge from Brandenburg freely accessible to all. + +Universities in Brandenburg: + University of Potsdam + Brandenburg University of Technology + European University Viadrina + Konrad Wolf Film University of Babelsberg + Medizinische Hochschule Brandenburg Theodor Fontane + +Culture + +Music +The Brandenburg Concertos by Johann Sebastian Bach (original title: Six Concerts à plusieurs instruments) are a collection of six instrumental works presented by Bach to Christian Ludwig, Margrave of Brandenburg-Schwedt, in 1721 (though probably composed earlier).

It is the only federal representative body that is directly elected by the German people, comparable to the United States House of Representatives or the House of Commons of the United Kingdom. The Bundestag was established by Title III of the Basic Law for the Federal Republic of Germany (, ) in 1949 as one of the legislative bodies of Germany and thus it is the historical successor to the earlier Reichstag. + +The members of the Bundestag are representatives of the German people as a whole, are not bound by any orders or instructions and are only accountable to their electorate. The minimum legal number of members of the Bundestag () is 598; however, due to the system of overhang and leveling seats the current 20th Bundestag has a total of 736 members, making it the largest Bundestag to date and the largest freely elected national parliamentary chamber in the world. + +The Bundestag is elected every four years by German citizens aged 18 or over. Elections use a mixed-member proportional representation system which combines first-past-the-post elected seats with a proportional party list to ensure its composition mirrors the national popular vote. An early election is only possible in the cases outlined in Articles 63 and 68 of the Grundgesetz + +The Bundestag has several functions. It is the chief legislative body on the federal level. The individual states () of Germany participate in the legislative process through the Bundesrat, a separate assembly. The Bundestag also elects and oversees the chancellor, Germany's head of government, and sets the government budget. + +Since 1999, it has met in the Reichstag building in Berlin. The Bundestag also operates in multiple new government buildings in Berlin and has its own police force (the Bundestagspolizei). The current president of the Bundestag since 2021 is Bärbel Bas of the SPD. The 20th Bundestag has five vice presidents and is the most visited parliament in the world. + +History + +Bundestag translates as "Federal Diet", with "" (cognate to English "bundle") in this context meaning federation, and "" (day) came to mean "meeting in conference" — another example being (similar to "diet", which is from Latin "", day). + +With the dissolution of the German Confederation in 1866 and the founding of the German Empire (German Reich) in 1871, the Reichstag was established as the German parliament in Berlin, which was the capital of the then Kingdom of Prussia (the largest and most influential state in both the Confederation and the empire). Two decades later, the current parliament building was erected. The Reichstag delegates were elected by direct and equal male suffrage (and not the three-class electoral system prevailing in Prussia until 1918). The Reichstag did not participate in the appointment of the chancellor until the parliamentary reforms of October 1918. After the Revolution of November 1918 and the establishment of the Weimar Constitution, women were given the right to vote for (and serve in) the Reichstag, and the parliament could use the no-confidence vote to force the chancellor or any cabinet member to resign. In 1933, Adolf Hitler was appointed chancellor and through the Reichstag Fire Decree, the Enabling Act of 1933 and the death of President Paul von Hindenburg in 1934, gained unlimited power. After this, the Reichstag met only rarely, usually at the Kroll Opera House to unanimously rubber-stamp the decisions of the government. It last convened on 26 April 1942. + +With the new constitution of 1949, the Bundestag was established as the new West German parliament. Because West Berlin was not officially under the jurisdiction of the constitution, a legacy of the Cold War, the Bundestag met in Bonn in several different buildings, including (provisionally) a former waterworks facility. In addition, owing to the city's legal status, citizens of West Berlin were unable to vote in elections to the Bundestag, and were instead represented by 22 non-voting delegates chosen by the House of Representatives, the city's legislature. + +The Bundeshaus in Bonn is the former parliament building of Germany. The sessions of the German Bundestag were held there from 1949 until its move to Berlin in 1999. Today it houses the International Congress Centre Bundeshaus Bonn and in the northern areas the branch office of the Bundesrat ("Federal Council"), which represents the – the federated states. The southern areas became part of German offices for the United Nations in 2008. + +The former Reichstag building housed a history exhibition () and served occasionally as a conference center. The Reichstag building was also occasionally used as a venue for sittings of the Bundestag and its committees and the Federal Convention, the body which elects the German federal president. However, the Soviets harshly protested against the use of the Reichstag building by institutions of the Federal Republic of Germany and tried to disturb the sittings by flying supersonic jets close to the building. + +Since 19 April 1999, the German parliament has again assembled in Berlin in its original Reichstag building, which was built in 1888 based on the plans of German architect Paul Wallot and underwent a significant renovation under the lead of British architect Lord Norman Foster. Parliamentary committees and subcommittees, public hearings and parliamentary group meetings take place in three auxiliary buildings, which surround the Reichstag building: the and . + +In 2005, a small aircraft crashed close to the German Parliament. It was then decided to ban private air traffic over Central Berlin. + +Tasks +Together with the Bundesrat, the Bundestag is the legislative branch of the German political system. + +Although most legislation is initiated by the executive branch, the Bundestag considers the legislative function its most important responsibility, concentrating much of its energy on assessing and amending the government's legislative program. The committees (see below) play a prominent role in this process. Plenary sessions provide a forum for members to engage in public debate on legislative issues before them, but they tend to be well attended only when significant legislation is being considered. + +The Bundestag members are the only federal officials directly elected by the public; the Bundestag in turn elects the chancellor and, in addition, exercises oversight of the executive branch on issues of both substantive policy and routine administration. This check on executive power can be employed through binding legislation, public debates on government policy, investigations, and direct questioning of the chancellor or cabinet officials. For example, the Bundestag can conduct a question hour (), in which a government representative responds to a written question previously submitted by a member. Members can ask related questions during the question hour. The questions can concern anything from a major policy issue to a specific constituent's problem. Use of the question hour has increased markedly over the past forty years, with more than 20,000 questions being posed during the 1987–90 term. The opposition parties actively exercise their parliamentary right to scrutinize government actions. + +Constituent services also take place via the Petition Committee. In 2004, the Petition Committee received over 18,000 complaints from citizens and was able to negotiate a mutually satisfactory solution to more than half of them. In 2005, as a pilot of the potential of internet petitions, a version of e-petitioner was produced for the Bundestag. This was a collaborative project involving The Scottish Parliament, International Teledemocracy Centre and the Bundestag 'Online Services Department'. The system was formally launched on 1 September 2005, and in 2008 the Bundestag moved to a new system based on its evaluation. + +Electoral term + +The Bundestag is elected for four years, and new elections must be held between 46 and 48 months after the beginning of its electoral term, unless the Bundestag is dissolved prematurely. Its term ends when the next Bundestag convenes, which must occur within 30 days of the election. Prior to 1976, there could be a period where one Bundestag had been dissolved and the next Bundestag could not be convened; during this period, the rights of the Bundestag were exercised by a so-called "Permanent Committee". + +Election + Germany uses the mixed-member proportional representation system, a system of proportional representation combined with elements of first-past-the-post voting. The Bundestag has 598 nominal members, elected for a four-year term; these seats are distributed between the sixteen German states in proportion to the states' population eligible to vote. + +Every elector has two votes: a constituency vote (first vote) and a party list vote (second vote). Based solely on the first votes, 299 members are elected in single-member constituencies by first-past-the-post voting. The second votes are used to produce a proportional number of seats for parties, first in the states, and then on the federal level. Seats are allocated using the Sainte-Laguë method. If a party wins fewer constituency seats in a state than its second votes would entitle it to, it receives additional seats from the relevant state list. Parties can file lists in every single state under certain conditions – for example, a fixed number of supporting signatures. Parties can receive second votes only in those states in which they have filed a state list. + +If a party, by winning single-member constituencies in one state, receives more seats than it would be entitled to according to its second vote share in that state (so-called overhang seats), the other parties receive compensation seats. Owing to this provision, the Bundestag usually has more than 598 members. The 20th and current Bundestag, for example, has 736 seats: 598 regular seats and 138 overhang and compensation seats. Overhang seats are calculated at the state level, so many more seats are added to balance this out among the different states, adding more seats than would be needed to compensate for overhang at the national level in order to avoid negative vote weight. + +To qualify for seats based on the party-list vote share, a party must either win three single-member constituencies via first votes (basic mandate clause) or exceed a threshold of 5% of the second votes nationwide. If a party only wins one or two single-member constituencies and fails to get at least 5% of the second votes, it keeps the single-member seat(s), but other parties that accomplish at least one of the two threshold conditions receive compensation seats. In the most recent example of this, during the 2002 election, the PDS won only 4.0% of the second votes nationwide, but won two constituencies in the state of Berlin. The same applies if an independent candidate wins a single-member constituency, which has not happened since the 1949 election. + +If a voter cast a first vote for a successful independent candidate or a successful candidate whose party failed to qualify for proportional representation, their second vote does not count toward proportional representation. However, it does count toward whether the elected party exceeds the 5% threshold. + +Parties representing recognized national minorities (currently Danes, Frisians, Sorbs, and Romani people) are exempt from both the 5% threshold and the basic mandate clause, but normally only run in state elections. The only party that has been able to benefit from this provision so far on the federal level is the South Schleswig Voters' Association, which represents the minorities of Danes and Frisians in Schleswig-Holstein and managed to win a seat in 1949 and 2021. + +Latest election result +The latest federal election was held on Sunday, 26 September 2021, to elect the members of the 20th Bundestag. + +List of Bundestag by session + +Presidents since 1949 + +Membership + +Organization + +Parliamentary groups + +The most important organisational structures within the Bundestag are parliamentary groups (Fraktionen; sing. Fraktion). A parliamentary group must consist of at least 5% of all members of parliament. Members of parliament from different parties may only join in a group if those parties did not run against each other in any German state during the election. Normally, all parties that surpassed the 5%-threshold build a parliamentary group. The CDU and CSU have always formed a single united Fraktion (CDU/CSU), which is possible, as the CSU only runs in the state of Bavaria and the CDU only runs in the other 15 states. The size of a party's Fraktion determines the extent of its representation on committees, the time slots allotted for speaking, the number of committee chairs it can hold, and its representation in executive bodies of the Bundestag. The Fraktionen, not the members, receive the bulk of government funding for legislative and administrative activities. + +The leadership of each Fraktion consists of a parliamentary party leader, several deputy leaders, and an executive committee. The leadership's major responsibilities are to represent the Fraktion, enforce party discipline and orchestrate the party's parliamentary activities. The members of each Fraktion are distributed among working groups focused on specific policy-related topics such as social policy, economics, and foreign policy. The Fraktion meets every Tuesday afternoon in the weeks in which the Bundestag is in session to consider legislation before the Bundestag and formulate the party's position on it. + +Parties that do not hold 5% of the Bundestag-seats may be granted the status of a Gruppe (literally "group", but a different status from Fraktion) in the Bundestag; this is decided case by case, as the rules of procedure do not state a fixed number of seats for this. Most recently, this applied to the Party of Democratic Socialism (PDS) from 1990 to 1998. This status entails some privileges which are in general less than those of a Fraktion. + +Executive bodies +The Bundestag's executive bodies include the Council of Elders and the Presidium. The council consists of the Bundestag leadership, together with the most senior representatives of each Fraktion, with the number of these representatives tied to the strength of the Parliamentary groups in the chamber. The council is the coordination hub, determining the daily legislative agenda and assigning committee chairpersons based on Parliamentary group representation. The council also serves as an important forum for interparty negotiations on specific legislation and procedural issues. The Presidium is responsible for the routine administration of the Bundestag, including its clerical and research activities. It consists of the chamber's president (usually elected from the largest Fraktion) and vice presidents (one from each Fraktion). + +Committees +Most of the legislative work in the Bundestag is the product of standing committees, which exist largely unchanged throughout one legislative period. The number of committees approximates the number of federal ministries, and the titles of each are roughly similar (e.g., defense, agriculture, and labor). There are, as of the current nineteenth Bundestag, 24 standing committees. The distribution of committee chairs and the membership of each committee reflect the relative strength of the various Parliamentary groups in the chamber. In the current nineteenth Bundestag, the CDU/CSU chaired ten committees, the SPD five, the AfD and the FDP three each, The Left and the Greens two each. Members of the opposition party can chair a significant number of standing committees (e.g. the budget committee is by tradition chaired by the biggest opposition party). These committees have either a small staff or no staff at all. + +Administration +The members of Bundestag and the presidium are supported by the Bundestag Administration. It is headed by the Director, that reports to the President of the Bundestag. +The Bundestag Administrations four departments are Parliament Service, Research, Information / Documentation and Central Affairs. +The Bundestag Administration employs around 3,000 employees. + +Principle of discontinuation +As is the case with some other parliaments, the Bundestag is subject to the principle of discontinuation, meaning that a newly elected Bundestag is legally regarded to be a body and entity completely different from the previous Bundestag. This leads to the result that any motion, application or action submitted to the previous Bundestag, e.g. a bill referred to the Bundestag by the Federal Government, is regarded as void by non-decision (German terminology: "Die Sache fällt der Diskontinuität anheim"). Thus any bill that has not been decided upon by the beginning of the new electoral period must be brought up by the government again if it aims to uphold the motion, this procedure in effect delaying the passage of the bill. Furthermore, any newly elected Bundestag will have to freshly decide on the rules of procedure (Geschäftsordnung), which is done by a formal decision of taking over such rules from the preceding Bundestag by reference. + +Any Bundestag (even after a snap election) is considered dissolved only once a newly elected Bundestag has actually gathered in order to constitute itself (Article 39 sec. 1 sentence 2 of the Basic Law), which has to happen within 30 days of its election (Article 39 sec. 2 of the Basic Law). Thus, it may happen (and has happened) that the old Bundestag gathers and makes decisions even after the election of a new Bundestag that has not gathered in order to constitute itself. For example, elections to the 16th Bundestag took place on 18 September 2005, but the 15th Bundestag still convened after election day to make some decisions on German military engagement abroad, and was entitled to do so, as the newly elected 16th Bundestag did not convene for the first time until 18 October 2005. + +See also + German governing coalition + Parliamentwatch + +References +Informational notes + +Citations + +External links + + + German election database + Map of constituencies + Distribution of power + Plenary speech search engine + + +Germany +Germany +Bundesrat is a German word that means federal council and may refer to: + Federal Council (Austria) + Bundesrat of Germany + Federal Council (Switzerland) + Bundesrat (German Empire) +Bayerische Motoren Werke AG, abbreviated as BMW (), is a German multinational manufacturer of luxury vehicles and motorcycles headquartered in Munich, Bavaria, Germany. The company was founded in 1916 as a manufacturer of aircraft engines, which it produced from 1917 to 1918 and again from 1933 to 1945. + +Automobiles are marketed under the brands BMW, Mini and Rolls-Royce, and motorcycles are marketed under the brand BMW Motorrad. In 2017, BMW was the world's fourteenth-largest producer of motor vehicles, with 2,279,503 vehicles produced and in 2022 the 7th largest by revenue. The company has significant motor-sport history, especially in touring cars, sports cars, and the Isle of Man TT. + +BMW is headquartered in Munich and produces motor vehicles in Germany, Brazil, China, India, Mexico, the Netherlands, South Africa, the United Kingdom, and the United States. The Quandt family is a long-term shareholder of the company, following investments by the brothers Herbert and Harald Quandt in 1959 that saved BMW from bankruptcy, with the remaining shares owned by the public. + +History + +Otto Flugmaschinenfabrik was founded in 1910 by Gustav Otto in Bavaria. The firm was reorganized on 7 March 1916 into Bayerische Flugzeugwerke AG. This company was then renamed to Bayerische Motoren Werke (BMW) in 1922. However, the name BMW dates back to 1913, when the original company to use the name was founded by Karl Rapp (initially as Rapp Motorenwerke GmbH). The name and Rapp Motorenwerke's engine-production assets were transferred to Bayerische Flugzeugwerke in 1922, who adopted the name the same year. BMW's first product was a straight-six aircraft engine called the BMW IIIa, designed in the spring of 1917 by engineer Max Friz. Following the end of World War I, BMW remained in business by producing motorcycle engines, farm equipment, household items and railway brakes. The company produced its first motorcycle, the BMW R 32 in 1923. + +BMW became an automobile manufacturer in 1928 when it purchased Fahrzeugfabrik Eisenach, which, at the time, built Austin Sevens under licence under the Dixi marque. The first car sold as a BMW was a rebadged Dixi called the BMW 3/15, following BMW's acquisition of the car manufacturer Automobilwerk Eisenach. Throughout the 1930s, BMW expanded its range into sports cars and larger luxury cars. + +Aircraft engines, motorcycles, and automobiles would be BMW's main products until World War II. During the war, BMW concentrated on aircraft engine production using as many as 40,000 slave laborers. These consisted primarily of prisoners from concentration camps, most prominently Dachau. Motorcycles remained as a side-line and automobile manufacture ceased altogether. + +BMW's factories were heavily bombed during the war and its remaining West German facilities were banned from producing motor vehicles or aircraft after the war. Again, the company survived by making pots, pans, and bicycles. In 1948, BMW restarted motorcycle production. BMW resumed car production in Bavaria in 1952 with the BMW 501 luxury saloon. The range of cars was expanded in 1955, through the production of the cheaper Isetta microcar under licence. Slow sales of luxury cars and small profit margins from microcars meant BMW was in serious financial trouble and in 1959 the company was nearly taken over by rival Daimler-Benz. + +A large investment in BMW by Herbert Quandt and Harald Quandt resulted in the company surviving as a separate entity. The Quandts' father, Günther Quandt, was a well-known German industrialist. Quandt joined the Nazi party in 1933 and made a fortune arming the German Wehrmacht, manufacturing weapons and batteries. Many of his enterprises were appropriated from Jewish owners under duress with minimal compensation. At least three of his enterprises made extensive use of slave laborers, as many as 50,000 in all. One of his battery factories had its own on-site concentration camp, complete with gallows. Life expectancy for laborers was six months. While Quandt and BMW were not directly connected during the war, funds amassed in the Nazi era by his father allowed Herbert Quandt to buy BMW. + +The relative success of the small BMW 700 assisted in the company's recovery, allowing them to develop the New Class sedans. + +The 1962 introduction of the BMW New Class compact sedans was the beginning of BMW's reputation as a leading manufacturer of sport-oriented cars. Throughout the 1960s, BMW expanded its range by adding coupé and luxury sedan models. The BMW 5 Series mid-size sedan range was introduced in 1972, followed by the BMW 3 Series compact sedans in 1975, the BMW 6 Series luxury coupés in 1976 and the BMW 7 Series large luxury sedans in 1978. + +The BMW M division released its first road car, a mid-engine supercar, in 1978. This was followed by the BMW M5 in 1984 and the BMW M3 in 1986. Also in 1986, BMW introduced its first V12 engine in the 750i luxury sedan. + +The company purchased the Rover Group in 1994, however the takeover was not successful and was causing BMW large financial losses. In 2000, BMW sold off most of the Rover brands, retaining only the Mini brand. + +In 1998, BMW also acquired the rights to the Rolls-Royce brand from Vickers Plc. + +The 1995 BMW Z3 expanded the line-up to include a mass-production two-seat roadster and the 1999 BMW X5 was the company's entry into the SUV market. + +The first modern mass-produced turbocharged petrol engine was introduced in 2006, (from 1973 to 1975, BMW built 1672 units of a turbocharged M10 engine for the BMW 2002 turbo), with most engines switching over to turbocharging over the 2010s. The first hybrid BMW was the 2010 BMW ActiveHybrid 7, and BMW's first mass-production electric car was the BMW i3 city car, which was released in 2013, (from 1968 to 1972, BMW built two battery-electric BMW 1602 Elektro saloons for the 1972 Olympic Games). After many years of establishing a reputation for sporting rear-wheel drive cars, BMW's first front-wheel drive car was the 2014 BMW 2 Series Active Tourer multi-purpose vehicle (MPV). + +In January 2021, BMW announced that its sales in 2020 fell by 8.4% due to the impact of the COVID-19 pandemic and the restrictions. However, in the fourth quarter of 2020, BMW witnessed a rise of 3.2% in its customers' demands. + +On 18 January 2022, BMW announced a new limited edition M760Li xDrive simply called "The Final V12," the last BMW series production vehicle to be fitted with a V-12 engine. + +BMW and Toyota aim to sell jointly-developed hydrogen fuel cell vehicles as soon as 2025. + +On October 5, 2023, it was announced that BMW UK CEO Chris Brownridge will succeed Torsten Müller-Ötvös as the CEO of Rolls-Royce starting December 1, 2023, as a result of Müller-Ötvös retiring. + +Branding + +Company name +BMW is an abbreviation for Bayerische Motoren Werke (). This name is grammatically incorrect (in German, compound words must not contain spaces), which is why the grammatically correct form of the name, Bayerische Motorenwerke () has been used in several publications and advertisements in the past.Roland Löwisch: BMW - Die schönsten Modelle: 100 Jahre Design und Technik' by azar'. HEEL, 2016, . p 7. Bayerische Motorenwerke translates into English as Bavarian Motor Works. The suffix AG, short for Aktiengesellschaft, signifies an incorporated entity owned by shareholders, thus akin to "Inc." (US) or PLC, "Public Limited Company" (UK). + +The terms Beemer, Bimmer and Bee-em are sometimes used as slang for BMW in the English language and are sometimes used interchangeably for cars and motorcycles. + + Logo +The circular blue and white BMW logo or roundel evolved from the circular Rapp Motorenwerke company logo, which featured a black ring bearing the company name surrounding the company logo, on a plinth a horse's head couped. + +BMW retained Rapp's black ring inscribed with the company name, but adopted as the central element a circular escutcheon bearing a quasi-heraldic reference to the coat of arms (and flag) of the Free State of Bavaria (as the state of their origin was named after 1918), being the arms of the House of Wittelsbach, Dukes and Kings of Bavaria. However, as the local law regarding trademarks forbade the use of state coats of arms or other symbols of sovereignty on commercial logos, the design was sufficiently differentiated to comply, but retained the tinctures azure (blue) and argent (white).The heraldic blazon of the BMW quasi-heraldic circular escutcheon is Quarterly of 4: 1&4: Azure; 2&3: Argent + +The current iteration of the logo was introduced in 2020, removing 3D effects that had been used in previous renderings of the logo while removing the black outline encircling the rondel. The logo is used for BMW's branding but it is not used on vehicles. + +The origin of the logo as a portrayal of the movement of an aircraft propeller, the BMW logo with the white blades seeming to cut through a blue sky, is a myth which sprang from a 1929 BMW advertisement depicting the BMW emblem overlaid on a rotating propeller, with the quarters defined by strobe-light effect, a promotion of an aircraft engine then being built by BMW under license from Pratt & Whitney. It is well established that this propeller portrayal was first used in a BMW advertisement in 1929 – twelve years after the logo was created – so this is not the true origin of the logo. + + Slogan +The slogan 'The Ultimate Driving Machine' was first used in North America in 1974. In 2010, this long-lived campaign was mostly supplanted by a campaign intended to make the brand more approachable and to better appeal to women, 'Joy'. By 2012 BMW had returned to 'The Ultimate Driving Machine'. + + Finances +For the fiscal year 2017, BMW reported earnings of EUR 8.620 billion, with an annual revenue of EUR 98.678 billion, an increase of 4.8% over the previous fiscal cycle. BMW's shares traded at over €77 per share, and its market capitalization was valued at US 55.3 billion in November 2018. + +Motorcycles + +BMW began production of motorcycle engines and then motorcycles after World War I. Its motorcycle brand is now known as BMW Motorrad. Their first successful motorcycle after the failed Helios and Flink, was the "R32" in 1923, though production originally began in 1921. This had a "boxer" twin engine, in which a cylinder projects into the air-flow from each side of the machine. Apart from their single-cylinder models (basically to the same pattern), all their motorcycles used this distinctive layout until the early 1980s. Many BMW's are still produced in this layout, which is designated the R Series. + +The entire BMW Motorcycle production has, since 1969, been located at the company's Berlin-Spandau factory. + +During the Second World War, BMW produced the BMW R75 motorcycle with a motor-driven sidecar attached, combined with a lockable differential, this made the vehicle very capable off-road. + +In 1982, came the K Series, shaft drive but water-cooled and with either three or four cylinders mounted in a straight line from front to back. Shortly after, BMW also started making the chain-driven F and G series with single and parallel twin Rotax engines. + +In the early 1990s, BMW updated the airhead Boxer engine which became known as the oilhead. In 2002, the oilhead engine had two spark plugs per cylinder. In 2004 it added a built-in balance shaft, an increased capacity to and enhanced performance to for the R1200GS, compared to of the previous R1150GS. More powerful variants of the oilhead engines are available in the R1100S and R1200S, producing , respectively. + +In 2004, BMW introduced the new K1200S Sports Bike which marked a departure for BMW. It had an engine producing , derived from the company's work with the Williams F1 team, and is lighter than previous K models. Innovations include electronically adjustable front and rear suspension, and a Hossack-type front fork that BMW calls Duolever. + +BMW introduced anti-lock brakes on production motorcycles starting in the late 1980s. The generation of anti-lock brakes available on the 2006 and later BMW motorcycles paved the way for the introduction of electronic stability control, or anti-skid technology later in the 2007 model year. + +BMW has been an innovator in motorcycle suspension design, taking up telescopic front suspension long before most other manufacturers. Then they switched to an Earles fork, front suspension by swinging fork (1955 to 1969). Most modern BMWs are truly rear swingarm, single sided at the back (compare with the regular swinging fork usually, and wrongly, called swinging arm). +Some BMWs started using yet another trademark front suspension design, the Telelever, in the early 1990s. Like the Earles fork, the Telelever significantly reduces dive under braking. + +BMW Group, on 31 January 2013, announced that Pierer Industrie AG has bought Husqvarna Motorcycles for an undisclosed amount, which will not be revealed by either party in the future. The company is headed by Stephan Pierer (CEO of KTM). Pierer Industrie AG is 51% owner of KTM and 100% owner of Husqvarna. + +In September 2018, BMW unveiled a new self-driving motorcycle with BMW Motorrad with a goal of using the technology to help improve road safety. The design of the bike was inspired by the company's BMW R1200 GS model. + + Automobiles + Current models + +The current model lines of BMW cars are: + 1 Series five-door hatchbacks (model code F40). A four-door sedan variant (model code F52) is also sold in China and Mexico. + 2 Series two-door coupes (model code G42), "Active Tourer" five-seat MPVs (U06) and four-door "Gran Coupe" fastback sedans (model code F44). + 3 Series four-door sedans (model code G20) and five-door station wagons (G21). + 4 Series two-door coupes (model code G22), two-door convertibles (model code G23) and five-door "Gran Coupe" fastbacks (model code G26). + 5 Series four-door sedans (model code G30) and five-door station wagons (G31).

Since Calder's work of art, many other renowned artists throughout the world have created BMW Art Cars, including David Hockney, Jenny Holzer, Roy Lichtenstein, Robert Rauschenberg, Frank Stella, and Andy Warhol. To date, a total of 19 BMW Art Cars, based on both racing and regular production vehicles, have been created. + + Architecture + +The global BMW Headquarters in Munich represents the cylinder head of a 4-cylinder engine. It was designed by Karl Schwanzer and was completed in 1972. The building has become a European icon and was declared a protected historic building in 1999. The main tower consists of four vertical cylinders standing next to and across from each other. Each cylinder is divided horizontally in its center by a mold in the facade. Notably, these cylinders do not stand on the ground; they are suspended on a central support tower. + +BMW Museum is a futuristic cauldron-shaped building, which was also designed by Karl Schwanzer and opened in 1972. The interior has a spiral theme and the roof is a 40-metre diameter BMW logo. + +BMW Welt, the company's exhibition space in Munich, was designed by Coop Himmelb(l)au and opened in 2007.

It has usually been ruled by Denmark, but also by Sweden and by Lübeck. The ruin of Hammershus, at the northwestern tip of the island, is the largest medieval fortress in northern Europe, testament to the importance of its location. Bornholm and Ertholmene comprise the last remaining Danish territory in Skåneland east of Øresund, having been surrendered to Sweden in 1658, but regained by Denmark in 1660 after a local revolt. + +The island is known as ("sunshine island") because of its weather and ("rock island") because of its geology, which consists of granite, except along the southern coast. The heat from the summer is stored in the rock formations and the weather is quite warm until October. As a result of the climate, a local variety of the common fig, known as Bornholm's Diamond (Bornholms Diamant), can grow locally on the island. The island's topography consists of dramatic rock formations in the north (unlike the rest of Denmark, which is mostly gentle rolling hills) sloping down towards pine and deciduous forests (greatly affected by storms in the 1950s), farmland in the middle and sandy beaches in the south. + +The island is home to many of Denmark's round churches. Occupying an area of , the island had a total population of 39,602 . + +History + +Medieval + +In Old Norse the island was known as Burgundaholmr, and in ancient Danish especially the island's name was Borghand or Borghund; these names were related to Old Norse borg 'height' and bjarg/berg 'mountain, rock' because it is an island that rises high from the sea. Other names known for the island include Burgendaland (9th century), Hulmo / Holmus (Gesta Hammaburgensis ecclesiae pontificum), Burgundehulm (1145), and Borghandæholm (14th century). The Old English translation of Orosius uses the form Burgenda land. Some scholars believe that the Burgundians are named after Bornholm. The Burgundians were Germanic peoples who moved west when the Western Roman Empire collapsed and occupied and named Burgundy in France. + +Bornholm formed part of the historical Lands of Denmark when the nation united out of a series of petty chiefdoms. It was originally administratively part of the province of Scania and was administered by the Scanian Law after this was codified in the 13th century. Control over the island evolved into a long-raging dispute between the See of Lund and the Danish crown, culminating in several battles. The first fortress on the island was Gamleborg, which was replaced by Lilleborg built by the king in 1150. In 1149 the king accepted the transfer of three of the island's four herreder (districts) to the archbishop. In 1250, the archbishop constructed his own fortress, Hammershus. A campaign launched from it in 1259 conquered the remaining part of the island including Lilleborg. The island's status remained a matter of dispute for an additional 200 years. + +Modern + +Bornholm was pawned to Lübeck for 50 years starting in 1525. Its first militia, Bornholms Milits, was formed in 1624. Swedish forces conquered the island in 1645, but returned the island to Denmark in the following peace settlement. After the war in 1658, Denmark ceded the island to Sweden under the Treaty of Roskilde along with the rest of the Skåneland, Bohuslän and Trøndelag, and it was occupied by Swedish forces. +A revolt broke out the same year, culminating in Villum Clausen's shooting of the Swedish commander Johan Printzensköld on 8 December 1658. Following the revolt, a deputation of islanders presented the island as a gift to King Frederick III of Denmark on the condition that the island would never be ceded again. This status was confirmed in the Treaty of Copenhagen in 1660. + +Swedes, notably from Småland and Scania, emigrated to the island during the 19th century, seeking work and better conditions. Most of the migrants did not remain. + +Bornholm also attracted many famous artists at the beginning of the 20th century, forming a group now known as the Bornholm school of painters. In addition to Oluf Høst, they include Karl Isaksson (1878–1922) from Sweden, and the Danes Edvard Weie (1879–1943), Olaf Rude (1886–1957), Niels Lergaard (1893–1982), and Kræsten Iversen (1886–1955). + +German and Soviet occupation +Bornholm, as a part of Denmark, was captured by Nazi Germany on 10 April 1940, and served as a lookout post and listening station during the war, as it was a part of the Eastern Front. The island's perfect central position in the Baltic Sea meant that it was an important "natural fortress" between Germany and Sweden, effectively keeping submarines and destroyers away from Nazi-occupied waters. Several concrete coastal installations were built during the war, as well as several coastal batteries, which had tremendous range. However, none of them were ever used, and only a single test shot was fired during the occupation. These remnants of Nazi rule have since fallen into disrepair and are mostly regarded today as historical curiosities. Many tourists visit the ruins each year, however, providing supplemental income to the tourist industry. + +On 22 August 1942 a V-1 flying bomb (numbered V83, probably launched from a Heinkel He 111) crashed on Bornholm during a test – the warhead was a dummy made of concrete. The wreckage was photographed and sketched by the Danish Naval Officer-in-Charge on Bornholm, Lieutenant Commander Hasager Christiansen. This was one of the first signs British Intelligence saw of Germany's aspirations to develop flying bombs and rockets which were to become known as V-1. The Bornholm rocket turned out to be from Peenemünde. + +Bornholm was heavily bombarded by the Soviet Air Forces in May 1945, as it was a part of the Eastern Front. The German garrison commander, German Navy Captain Gerhard von Kamptz (1902–1998), refused to surrender to the Soviets, as his orders were to surrender only to the Western Allies. The Germans sent several telegrams to Copenhagen requesting that at least one British soldier should be transferred to Bornholm, so that the Germans could surrender to the Western Allied forces instead of the Soviets. When von Kamptz failed to provide a written capitulation as demanded by the Soviet commanders, Soviet aircraft relentlessly bombed and destroyed more than 800 civilian houses in Rønne and in Nexø, and seriously damaged roughly 3,000 more on 7–8 May 1945. The population had been forewarned of the bombardments, and the towns were evacuated, but 10 local people were killed. Soldiers were also killed and wounded. Some of them were conscripts from occupied Latvia fighting in German ranks against the Soviets. + +During the Soviet bombing of the two main towns on 7-8 May, Danish radio was not allowed to broadcast the news because it was thought it would spoil the liberation festivities in Denmark. On 9 May Soviet troops landed on the island, and after a short fight, the German garrison (about 12,000 strong) surrendered. Soviet forces left the island on 5 April 1946. + +Cold War +After the evacuation of their forces from Bornholm, the Soviets took the position that the stationing of foreign troops on Bornholm would be considered a declaration of war against the Soviet Union, and that Denmark should keep troops on it at all times to protect it from such foreign aggression. This policy remained in force after NATO was formed, with Denmark as a founding member. The Soviets accepted the stationing there of Danish troops, which were part of NATO but viewed as militarily inferior elements of the alliance, but they strongly objected to the presence of other NATO troops on Bornholm, US troops in particular. + +On 5 March 1953, the day of Stalin's death, Polish pilot Franciszek Jarecki defected from the Eastern Bloc and landed a MiG-15 fighter on the island. He was later granted asylum and rewarded for providing Western intelligence with the then-newest Soviet jet fighter. + +In 2017, Denmark's Defence Intelligence Service decided to build a listening tower near Østermarie, almost 90 meters high, to intercept radio communications across the Baltic Sea and in parts of Russia. + +Municipality + + + + +Bornholm Regional Municipality is the local authority (Danish, kommune) covering the entire island. Its formal name is Bornholm Municipality. It is given the right in the law establishing it to be called Bornholm Regional Municipality. (For explanation read on). It is the result of a merger of the five former (1 April 1970 until 2002) municipalities on the island (Allinge-Gudhjem, Hasle, Nexø, Rønne and Aakirkeby) and the former Bornholm County. Bornholm Regional Municipality was also a county in its own right during its first four years from 1 January 2003 until 31 December 2006. From 1 January 2007 all counties were abolished, and Bornholm became part of the Capital Region of Denmark whose main responsibility is the health service. In the bill (Danish forslag) (Bill of Law on merger of the municipalities of Bornholm) presented 30 January 2002 by the Minister of Interior and Health to Folketinget, it says in §1 that (1st sentence) "The 1st of January 2003 Bornholm Municipality is established by a merger of (names of municipalities mentioned, and county's name mentioned), and (2nd sentence) Bornholm Municipality is called Bornholm Regional Municipality". + +The island had 21 municipalities until March 1970, of which 6 were market towns and 15 parishes. In addition to supervising parish municipalities, which was the responsibility of the counties in all of Denmark, the market town municipalities of Bornholm were supervised by Bornholm County as well and not by the Interior Ministry as was the case in the rest of Denmark. The seat of the municipal council is the island's main town, Rønne. The voters decided to merge the county with the municipalities in a referendum 29 May 2001, effective from 1 January 2003. The question on the ballot was, "Do you want the six municipal entities of Bornholm to be joined to form one municipal entity as of 1 January 2003?" 73.9% voted in favour. The lowest percentage for the merger was in Nexø municipality (966 more people voting "Yes" than "No"), whose mayor, Annelise Molin, a Social Democrat, spoke out against the merger. It was required that each municipality had more "Yes" votes than "No" votes. Otherwise the merger would have to be abandoned altogether. The six municipal entities had up to 122 councillors (of which county clls were 18, from 1998 15), reduced to 89 in the municipalities from the 1990s, in the 1970s and the new regional municipality would have 27 councillors from the start 1 January 2003. They were reduced to 23 from 1 January 2018 (election November 2017). From 1 January 2003 until 31 December 2006 the 27 cllrs were called Regional Council (Danish Regionsråd), from 1 January 2007 changed to Municipal Board (Danish Kommunalbestyrelse) as is the usual term in almost all Danish municipalities. This was to avoid confusion with the Regional Council in Region Hovedstaden, and in the other regions + +The merger was approved in a law by the Folketing 19 (and signature by the head of state 25) March 2002, transferring the tasks of the abolished county and old municipalities to the new Bornholm Regional Municipality. The first regional mayor in the first three years from 2003 until 2005 was Thomas Thors (born 28 July 1949), a physician and member of the Social Democrats and previously the last mayor of Rønne Municipality for five years from 1998 until 2002. He became a mayor again in 2021. Bjarne Kristiansen, who was the last mayor of Hasle years from the summer of 2000 until 2002, representing the local Borgerlisten political party, served as mayor for four years from 1 January 2006 until 2009. From 1 January 2007, Bornholm became a part of the Capital Region of Denmark. From 1 January 2010 until 31 December 2020 the mayor was Winni Grosbøll, a high school teacher and a member of the Social Democrats (Socialdemokratiet) political party. The deputy mayor Morten Riis was mayor for a short interlude from 1 January until 4 January 2021. He is from the Red-Green Alliance. Thomas Thors, who was elected again in 2017, became mayor again from 4 January 2021. After the 2021 Danish local elections Jacob Trøst became mayor from January 2022. He is from the Conservative party. This was after an agreement (aftale om konstituering) between the Red-Green Alliance, amongst whom Morten Riis will be deputy mayor, and the Danish People's Party with the Conservatives. + +Municipal council +Bornholm's municipal council today consists of 23 members, elected every four years. In the first four local elections in the newly created municipality there were 27 members elected to the municipal council. The 2002 local election only took place on Bornholm. From the election in 2017 the number of councillors elected was reduced to 23 members, serving their term of office from 1 January 2018 until 31 December 2021. + +Below are the election results to the new merged municipal council beginning with the first election 29 May 2002. + +Transport + +Ferry services connect Rønne to Świnoujście (Poland), Sassnitz (Germany), Køge, by road ( as the crow flies) south of Copenhagen, Denmark; the destination to Køge replaced the nighttime route directly to and from Copenhagen (for both cargo and passengers) from 1 October 2004; and catamaran services to Ystad (Sweden). Simrishamn (Sweden) has a ferry connection during the summer. There are also regular catamaran services between Nexø and the Polish ports of Kołobrzeg, Łeba and Ustka. There are direct bus connections Ystad-Copenhagen, coordinated with the catamaran. There are also flights from Bornholm Airport to Copenhagen and other locations. + +Because of its remote location Bornholm Regional Municipality has its own traffic company, BAT, and is its own employment region, and also performs other tasks normally carried out by the regions in the rest of Denmark. In some respects the municipality forms a region of its own. + +Bornholm Regional Municipality was not merged with other municipalities on 1 January 2007 in the nationwide Municipal Reform of 2007. + +Towns and villages +The larger towns on the island are located on the coast and have harbours. There is however one exception, centrally placed Aakirkeby, which was also the name of the municipality from 1970 until 2002, but it included the harbour of Boderne, to the south. The largest town is Rønne; it is the seat, in the southwest on the westernmost point of the island. The other main towns (clockwise around the island) are Hasle, Sandvig, Allinge, Gudhjem, Svaneke and Nexø. Monday morning 22 September 2014 it was documented by Folkeregistret in the municipality that the number of people living in the municipality that day were 39,922, the lowest number in over 100 years. + +, Statistics Denmark gave the populations as follows: + +The town of Rønne after the merger of the island's administrative entities 1 January 2003 reached a low point of 13,568 inhabitants 1 January 2014. 15,957 people in 1965 (date unknown;number not registerbased) lived in the two parishes that would become Rønne municipality from 1 April 1970. In the table, numbers for Rønne are for the parish of Rønne, Rønne Sogn, alone. The year is unknown but sometime between 2000 and 2005. It does not include Knudsker Sogn, which was also part of Rønne Municipality. Other localities (with approximate populations, not updated) include Aarsballe (86), Arnager (151), Olsker (67), Rutsker (64), Rø (181), Stenseby (?) and Vang (92). In 2010 and 2018 10,297 and 9,111 respectively lived in rural districts, and 88 and 71 had no fixed address. A rural district is defined by Statistics Denmark as a settlement with less than 200 inhabitants. + +Demography + +Population of parishes +Year: Beginning with 2007; 2018; + 7552.

Christiansø Parish (which encompasses Ertholmene) is not a part of Bornholm Regional Municipality. It is included because Danmarks Statistik includes it as parish number 7568. Bornholm has 21 parishes (2018) that before 1 April 1970 were parish (15) or market city (6) municipalities themselves. There are 2,158 parishes (2021) in the Church of Denmark. + +Source:Statistikbanken.dk/Befolkning og valg/(table)FODIE (births);FOD207 (deaths);BEV107 (births;deaths;birth surplus);KM1 (parishes). + +On 22 September 2014 population numbers showed fewer than 40,000 inhabitants on the island for the first time in over 100 years. The Folkeregister in the municipality could document 39,922 inhabitants in the municipality on that date. + +Language + +Many inhabitants speak the Bornholmsk dialect, which is officially a dialect of Danish. Bornholmsk retains three grammatical genders, like Faroese, Icelandic and most dialects of Norwegian, but unlike standard Danish. Its phonology includes archaisms (unstressed and internal , where other dialects have and ) and innovations ( for before and after front vowels). This makes the dialect difficult to understand for some Danish speakers. However, Swedish speakers often consider Bornholmian to be easier to understand than standard Danish. The intonation resembles the dialects spoken in nearby Scania, Blekinge and Halland the southernmost provinces of Sweden. + +Religion +Most inhabitants are members of the Lutheran Church of Denmark (Folkekirken). Various Christian denominations have become established on the island, most during the 19th century. +Folkekirken (State church) (1536) +Baptist church (1843) +The Church of Jesus Christ of Latter-day Saints (LDS Church) (1850) +Methodist church (1895) +Jehovah's Witnesses (1897) +Roman Catholic Church (ca 1150–1536, 1849) + +Sights and landmarks + +On the surface of Bornholm older geological formations can be seen better than in the rest of Denmark. Stubbeløkken – which is still operating (Danish i drift) – and Klippeløkken granite quarries in Knudsker parish just east of central Rønne – and statistically a part of the town – are among the few remaining quarries of what was once many active quarries on the island. The island's varied geography and seascapes attract visitors to its many beauty spots from the Hammeren promontory in the northwest to the Almindingen forest in the centre and the Dueodde beaches in the southeast. Of special interest are the rocky sea cliffs at Jons Kapel and Helligdomsklipperne, the varied topography of Paradisbakkerne and rift valleys such as Ekkodalen and Døndalen. Bornholm's numerous windmills include the post mill of Egeby and the well-kept Dutch mill at Aarsdale. The lighthouse at Dueodde is Denmark's tallest, while Hammeren Lighthouse stands at a height of above sea level and Rønne Lighthouse rises over the waterfront. + +Examples of roads that have (very) steep climbs and descents are: (inland) Simblegårdsvej in Klemensker, which begins by the village inn Klemens Kro, and Slamrebjergvej just outside Nexø extending northward from the main road from Rønne. Along the coast there are several steep roads, which is also the case in some parts of Denmark as a whole, for instance in and around Vejle. + +The island hosts examples of 19th- and early-20th-century architecture, and about 300 wooden houses in Rønne and Nexø, donated by Sweden after World War II, when the island was repairing damage caused by the war. +The island is home to 15 medieval churches, four of which are round churches with unique artwork and architecture. The ancient site of Rispebjerg has remains of sun temples from the Neolithic and earthworks from the Iron Age. + +There are 14 European bison near Åkirkeby, attracting 100,000 visitors a year. + +Education +Because of the dilapidated state of their buildings, all secondary educational facilities in Rønne, including adult evening classes, are being transferred to new facilities at Campus Bornholm in 2018. Campus Bornholm is a merger formed in June 2010 consisting of Bornholms Erhvervsskole (youth and adults), Bornholm High School (youth) and VUC Bornholm (adults), then occupying separate addresses. Learning institutions not part of this formalised collaboration will also be housed at Minervavej in Rønne. The building costs were over 300 million DKK (US$46.9 million (29 June 2018)). The A.P. Møller Foundation contributed a sum of 56 million DKK (US$8.76 million (29 June 2018)) to the project. + +Economy +Among Bornholm's chief industrial activities are dairy farming and arts and crafts industries such as glass production and pottery using locally worked clay. +Jensen-Group, an industrial washing and folding machine company, was founded on the island and has a factory in Rønne. It is headquartered in Belgium. + +Tourism is also important during the summer months. + +Electricity supply +Bornholm is connected to the Swedish electricity grid by a submarine 60 kV AC cable, which is among the longest AC cables in Europe. This cable is capable of delivering all the electrical energy consumed on Bornholm. However Bornholm also generates its own electricity at small thermal power plants and especially wind turbines. + +Bornholm is also home to a large internationally funded demonstration project to test the viability of novel energy market mechanisms to regulate energy networks with a high prevalence of renewables (such as wind turbines and photovoltaics). 50% of the EcoGrid project is EU-funded, with the remainder coming mainly from large corporations. + +Military + +Bornholm hosts a Marines like squadron (4th Basic Training Squadron), of the Guard Hussar Regiment at Almegårds Kaserne. + +Climate +Bornholm has an oceanic climate relatively similar to southern Sweden and mainland Denmark, whose summer highs and winter lows are heavily moderated by its maritime and isolated position. Though intense heat is rare, the climate is sunny during summer and rainfall is generally sparse for a climate of this type. The winter of 2010 – 2011 was exceptionally extreme with snow depth reaching at least 146 cm (58 inches) and snowdrifts of six meters (20 feet), the highest in Northern Europe. Military assistance was needed to clear roadways. The DMI estimated the weight of snow to be 100 million tons. + +Sports + +Bornholm's geography as an island and moderate climate makes Bornholm an ideal location for sailing and other water-based sports. Bornholm has also become an internationally recognised venue for 'match racing', a sailing sport where two identical yachts are raced in one-on-one events on the water. The Danish Open event was held in Bornholm in September 2010 at the port town of Rønne on the western coast of Bornholm. The five-day Danish Open is a key event in the World Match Racing Tour calendar which is one of only 3 events awarded 'special event' status by the International Sailing Federation. The Tour is the world's leading professional 'match racing' series and features a nine-event calendar which crosses three continents during the series. Points accrued during the Danish Open contribute directly to the World Match Racing Tour championship with the winner of the season finale at the Monsoon Cup in Malaysia claiming the ultimate match racing title ISAF World Match Racing Champion. + +There are two small stadiums: Nexø Stadion, in Nexø, where NB Bornholm association football club play; and the slightly larger multi-use stadium Rønne Stadion Nord in Rønne, which serves the Bornholm national football team, multi-section club most well known for athletics IK Viking, and several local football clubs. The DBU Bornholm is the local branch governing football on the island. + +Cultural references + Russian writer Nikolay Karamzin in his novella "The Island Bornholm" ("Ostrov Borngol'm") depicts formidable rocks and green meadows of the island.

It can also be a handwritten or printed work of fiction or nonfiction, usually on sheets of paper fastened or bound together within covers. The technical term for this physical arrangement is codex (plural, codices). In the history of hand-held physical supports for extended written compositions or records, the codex replaces its predecessor, the scroll. A single sheet in a codex is a leaf and each side of a leaf is a page. + +As an intellectual object, a book is prototypically a composition of such great length that it takes a considerable investment of time to compose and still considered as an investment of time to read. In a restricted sense, a book is a self-sufficient section or part of a longer composition, a usage reflecting that, in antiquity, long works had to be written on several scrolls and each scroll had to be identified by the book it contained. Each part of Aristotle's Physics is called a book. In an unrestricted sense, a book is the compositional whole of which such sections, whether called books or chapters or parts, are parts. + +The intellectual content in a physical book need not be a composition, nor even be called a book. Books can consist only of drawings, engravings or photographs, crossword puzzles or cut-out dolls. In a physical book, the pages can be left blank or can feature an abstract set of lines to support entries, such as in an account book, appointment book, autograph book, notebook, diary or sketchbook. Some physical books are made with pages thick and sturdy enough to support other physical objects, like a scrapbook or photograph album. Books may be distributed in electronic form as ebooks and other formats. + +Although in ordinary academic parlance a monograph is understood to be a specialist academic work, rather than a reference work on a scholarly subject, in library and information science monograph denotes more broadly any non-serial publication complete in one volume (book) or a finite number of volumes (even a novel like Proust's seven-volume In Search of Lost Time), in contrast to serial publications like a magazine, journal or newspaper. An avid reader or collector of books is a bibliophile or, colloquially, "bookworm". Books are traded at both regular stores and specialized bookstores, and people can read borrowed books, often for free, at libraries. Google has estimated that by 2010, approximately 130,000,000 titles had been published. + +In some wealthier nations, the sale of printed books has decreased because of the increased usage of e-books. However, in most countries, printed books continue to outsell their digital counterparts due to many people still preferring to read in a traditional way. The 21st century has also seen a rapid rise in the popularity of audiobooks, which are recordings of books being read aloud. + +Etymology +The word book comes from Old English , which in turn comes from the Germanic root , cognate to 'beech'. In Slavic languages like Russian, Bulgarian, Macedonian —'letter' is cognate with 'beech'. In Russian, Serbian and Macedonian, the word () or () refers to a primary school textbook that helps young children master the techniques of reading and writing. It is thus conjectured that the earliest Indo-European writings may have been carved on beech wood. The Latin word , meaning a book in the modern sense (bound and with separate leaves), originally meant 'block of wood'. + +History + +Antiquity + +When writing systems were created in ancient civilizations, a variety of objects, such as stone, clay, tree bark, metal sheets, and bones, were used for writing; these are studied in epigraphy. + +Tablet + +A tablet is a physically robust writing medium, suitable for casual transport and writing. Clay tablets were flattened and mostly dry pieces of clay that could be easily carried, and impressed with a stylus. They were used as a writing medium, especially for writing in cuneiform, throughout the Bronze Age and well into the Iron Age. Wax tablets were pieces of wood covered in a coating of wax thick enough to record the impressions of a stylus. They were the normal writing material in schools, in accounting, and for taking notes. They had the advantage of being reusable: the wax could be melted, and reformed into a blank. + +The custom of binding several wax tablets together (Roman pugillares) is a possible precursor of modern bound (codex) books. The etymology of the word codex (block of wood) also suggests that it may have developed from wooden wax tablets. + +Scroll + +Scrolls can be made from papyrus, a thick paper-like material made by weaving the stems of the papyrus plant, then pounding the woven sheet with a hammer-like tool until it is flattened. Papyrus was used for writing in Ancient Egypt, perhaps as early as the First Dynasty, although the first evidence is from the account books of King Neferirkare Kakai of the Fifth Dynasty (about 2400 BC). Papyrus sheets were glued together to form a scroll. Tree bark such as lime and other materials were also used. + +According to Herodotus (History 5:58), the Phoenicians brought writing and papyrus to Greece around the 10th or 9th century BC. The Greek word for papyrus as writing material (biblion) and book (biblos) come from the Phoenician port town Byblos, through which papyrus was exported to Greece. From Greek we also derive the word tome (), which originally meant a slice or piece and from there began to denote "a roll of papyrus". Tomus was used by the Latins with exactly the same meaning as volumen (see also below the explanation by Isidore of Seville). + +Whether made from papyrus, parchment, or paper, scrolls were the dominant form of book in the Hellenistic, Roman, Chinese, Hebrew, and Macedonian cultures. The Romans and Etruscans also made 'books' out of folded linen called in Latin Libri lintei, the only extant example of which is the Etruscan Liber Linteus. The more modern codex book format form took over the Roman world by late antiquity, but the scroll format persisted much longer in Asia. + +Codex + +Isidore of Seville (died 636) explained the then-current relation between a codex, book, and scroll in his Etymologiae (VI.13): "A codex is composed of many books; a book is of one scroll. It is called codex by way of metaphor from the trunks (codex) of trees or vines, as if it were a wooden stock, because it contains in itself a multitude of books, as it were of branches". Modern usage differs. + +A codex (in modern usage) is the first information repository that modern people would recognize as a "book": leaves of uniform size bound in some manner along one edge, and typically held between two covers made of some more robust material. The first written mention of the codex as a form of book is from Martial, in his Apophoreta CLXXXIV at the end of the first century, where he praises its compactness. However, the codex never gained much popularity in the pagan Hellenistic world, and only within the Christian community did it gain widespread use. This change happened gradually during the 3rd and 4th centuries, and the reasons for adopting the codex form of the book are several: the format is more economical, as both sides of the writing material can be used; and it is portable, searchable, and easy to conceal. A book is much easier to read, to find a page that you want, and to flip through. A scroll is more awkward to use. The Christian authors may also have wanted to distinguish their writings from the pagan and Judaic texts written on scrolls. In addition, some metal books were made, that required smaller pages of metal, instead of an impossibly long, unbending scroll of metal. A book can also be easily stored in more compact places, or side by side in a tight library or shelf space. + +Manuscripts + +The fall of the Roman Empire in the 5th century AD saw the decline of the culture of ancient Rome. Papyrus became difficult to obtain due to lack of contact with Egypt, and parchment, which had been used for centuries, became the main writing material. Parchment is a material made from processed animal skin and used, mainly in the past, for writing on, especially in the Middle Ages. Parchment is most commonly made of calfskin, sheepskin, or goatskin. It was historically used for writing documents, notes, or the pages of a book, and first came into use around the 200s BC. Parchment is limed, scraped and dried under tension. It is not tanned, and is thus different from leather. This makes it more suitable for writing on, but leaves it very reactive to changes in relative humidity and makes it revert to rawhide if overly wet. + +Monasteries carried on the Latin writing tradition in the Western Roman Empire. Cassiodorus, in the monastery of Vivarium (established around 540), stressed the importance of copying texts. St. Benedict of Nursia, in his Rule of Saint Benedict (completed around the middle of the 6th century) later also promoted reading. The Rule of Saint Benedict (Ch. XLVIII), which set aside certain times for reading, greatly influenced the monastic culture of the Middle Ages and is one of the reasons why the clergy were the predominant readers of books. The tradition and style of the Roman Empire still dominated, but slowly the peculiar medieval book culture emerged. + +Before the invention and adoption of the printing press, almost all books were copied by hand, which made books expensive and comparatively rare. Smaller monasteries usually had only a few dozen books, medium-sized perhaps a few hundred. By the 9th century, larger collections held around 500 volumes and even at the end of the Middle Ages, the papal library in Avignon and Paris library of the Sorbonne held only around 2,000 volumes. + +The scriptorium of the monastery was usually located over the chapter house. Artificial light was forbidden for fear it may damage the manuscripts. There were five types of scribes: + Calligraphers, who dealt in fine book production + Copyists, who dealt with basic production and correspondence + Correctors, who collated and compared a finished book with the manuscript from which it had been produced + Illuminators, who painted illustrations + Rubricators, who painted in the red letters + +The bookmaking process was long and laborious. The parchment had to be prepared, then the unbound pages were planned and ruled with a blunt tool or lead, after which the text was written by the scribe, who usually left blank areas for illustration and rubrication. Finally, the book was bound by the bookbinder. + +Different types of ink were known in antiquity, usually prepared from soot and gum, and later also from gall nuts and iron vitriol. This gave writing a brownish black color, but black or brown were not the only colors used. There are texts written in red or even gold, and different colors were used for illumination. For very luxurious manuscripts the whole parchment was colored purple, and the text was written on it with gold or silver (for example, Codex Argenteus). + +Irish monks introduced spacing between words in the 7th century. This facilitated reading, as these monks tended to be less familiar with Latin. However, the use of spaces between words did not become commonplace before the 12th century. It has been argued that the use of spacing between words shows the transition from semi-vocalized reading into silent reading. + +The first books used parchment or vellum (calfskin) for the pages. The book covers were made of wood and covered with leather. Because dried parchment tends to assume the form it had before processing, the books were fitted with clasps or straps. During the later Middle Ages, when public libraries appeared, up to the 18th century, books were often chained to a bookshelf or a desk to prevent theft. These chained books are called libri catenati. + +At first, books were copied mostly in monasteries, one at a time. With the rise of universities in the 13th century, the Manuscript culture of the time led to an increase in the demand for books, and a new system for copying books appeared. The books were divided into unbound leaves (pecia), which were lent out to different copyists, so the speed of book production was considerably increased. The system was maintained by secular stationers guilds, which produced both religious and non-religious material. + +Judaism has kept the art of the scribe alive up to the present. According to Jewish tradition, the Torah scroll placed in a synagogue must be written by hand on parchment and a printed book would not do, though the congregation may use printed prayer books and printed copies of the Scriptures are used for study outside the synagogue. A sofer "scribe" is a highly respected member of many Jewish communities. + +Middle East + +People of various religious (Jews, Christians, Zoroastrians, Muslims) and ethnic backgrounds (Syriac, Coptic, Persian, Arab etc.) in the Middle East also produced and bound books in the Islamic Golden Age (mid 8th century to 1258), developing advanced techniques in Islamic calligraphy, miniatures and bookbinding. A number of cities in the medieval Islamic world had book production centers and book markets. Yaqubi (died 897) says that in his time Baghdad had over a hundred booksellers. Book shops were often situated around the town's principal mosque as in Marrakesh, Morocco, that has a street named Kutubiyyin or book sellers in English and the famous Koutoubia Mosque is named so because of its location in this street. + +The medieval Muslim world also used a method of reproducing reliable copies of a book in large quantities known as check reading, in contrast to the traditional method of a single scribe producing only a single copy of a single manuscript. In the check reading method, only "authors could authorize copies, and this was done in public sessions in which the copyist read the copy aloud in the presence of the author, who then certified it as accurate." With this check-reading system, "an author might produce a dozen or more copies from a single reading," and with two or more readings, "more than one hundred copies of a single book could easily be produced." By using as writing material the relatively cheap paper instead of parchment or papyrus the Muslims, in the words of Pedersen "accomplished a feat of crucial significance not only to the history of the Islamic book, but also to the whole world of books". + +Wood block printing + +In woodblock printing, a relief image of an entire page was carved into blocks of wood, inked, and used to print copies of that page. This method originated in China, in the Han dynasty (before 220 AD), as a method of printing on textiles and later paper, and was widely used throughout East Asia. The oldest dated book printed by this method is The Diamond Sutra (868 AD). The method (called woodcut when used in art) arrived in Europe in the early 14th century. Books (known as block-books), as well as playing-cards and religious pictures, began to be produced by this method. Creating an entire book was a painstaking process, requiring a hand-carved block for each page; and the wood blocks tended to crack, if stored for long. The monks or people who wrote them were paid highly. + +Movable type and incunabula + +The Chinese inventor Bi Sheng made movable type of earthenware , but there are no known surviving examples of his printing. Around 1450, in what is commonly regarded as an independent invention, Johannes Gutenberg invented movable type in Europe, along with innovations in casting the type based on a matrix and hand mould. This invention gradually made books less expensive to produce and more widely available. + +Early printed books, single sheets and images which were created before 1501 in Europe are known as incunables or incunabula. "A man born in 1453, the year of the fall of Constantinople, could look back from his fiftieth year on a lifetime in which about eight million books had been printed, more perhaps than all the scribes of Europe had produced since Constantine founded his city in AD 330." + +19th century to 21st centuries +Steam-powered printing presses became popular in the early 19th century. These machines could print 1,100 sheets per hour, but workers could only set 2,000 letters per hour. Monotype and linotype typesetting machines were introduced in the late 19th century. They could set more than 6,000 letters per hour and an entire line of type at once. There have been numerous improvements in the printing press. As well, the conditions for freedom of the press have been improved through the gradual relaxation of restrictive censorship laws. See also intellectual property, public domain, copyright. In mid-20th century, European book production had risen to over 200,000 titles per year. + +Throughout the 20th century, libraries have faced an ever-increasing rate of publishing, sometimes called an information explosion. The advent of electronic publishing and the internet means that much new information is not printed in paper books, but is made available online through a digital library, on CD-ROM, in the form of ebooks or other online media. An on-line book is an ebook that is available online through the internet. Though many books are produced digitally, most digital versions are not available to the public, and there is no decline in the rate of paper publishing. There is an effort, however, to convert books that are in the public domain into a digital medium for unlimited redistribution and infinite availability. This effort is spearheaded by Project Gutenberg combined with Distributed Proofreaders. There have also been new developments in the process of publishing books. Technologies such as POD or "print on demand", which make it possible to print as few as one book at a time, have made self-publishing (and vanity publishing) much easier and more affordable. On-demand publishing has allowed publishers, by avoiding the high costs of warehousing, to keep low-selling books in print rather than declaring them out of print. + +Indian manuscripts + +Goddess Saraswati image dated 132 AD excavated from Kankali tila depicts her holding a manuscript in her left hand represented as a bound and tied palm leaf or birch bark manuscript. In India a bounded manuscript made of birch bark or palm leaf existed side by side since antiquity. The text in palm leaf manuscripts was inscribed with a knife pen on rectangular cut and cured palm leaf sheets; colouring was then applied to the surface and wiped off, leaving the ink in the incised grooves. Each sheet typically had a hole through which a string could pass, and with these the sheets were tied together with a string to bind like a book. + +Mesoamerican codices +The codices of pre-Columbian Mesoamerica (Mexico and Central America) had the same form as the European codex, but were instead made with long folded strips of either fig bark (amatl) or plant fibers, often with a layer of whitewash applied before writing. New World codices were written as late as the 16th century (see Maya codices and Aztec codices). Those written before the Spanish conquests seem all to have been single long sheets folded concertina-style, sometimes written on both sides of the local amatl paper. + +Modern manufacturing + +The methods used for the printing and binding of books continued fundamentally unchanged from the 15th century into the early 20th century. While there was more mechanization, a book printer in 1900 had much in common with Gutenberg. Gutenberg's invention was the use of movable metal types, assembled into words, lines, and pages and then printed by letterpress to create multiple copies. Modern paper books are printed on papers designed specifically for printed books. Traditionally, book papers are off-white or low-white papers (easier to read), are opaque to minimize the show-through of text from one side of the page to the other and are (usually) made to tighter caliper or thickness specifications, particularly for case-bound books. Different paper qualities are used depending on the type of book: Machine finished coated papers, woodfree uncoated papers, coated fine papers and special fine papers are common paper grades. + +Today, the majority of books are printed by offset lithography. When a book is printed, the pages are laid out on the plate so that after the printed sheet is folded the pages will be in the correct sequence. Books tend to be manufactured nowadays in a few standard sizes. The sizes of books are usually specified as "trim size": the size of the page after the sheet has been folded and trimmed. The standard sizes result from sheet sizes (therefore machine sizes) which became popular 200 or 300 years ago, and have come to dominate the industry. British conventions in this regard prevail throughout the English-speaking world, except for the US. The European book manufacturing industry works to a completely different set of standards. + +Processes + +Layout + +Modern bound books are organized according to a particular format called the book's layout. Although there is great variation in layout, modern books tend to adhere to a set of rules with regard to what the parts of the layout are and what their content usually includes. A basic layout will include a front cover, a back cover and the book's content which is called its body copy or content pages. The front cover often bears the book's title (and subtitle, if any) and the name of its author or editor(s). The inside front cover page is usually left blank in both hardcover and paperback books. The next section, if present, is the book's front matter, which includes all textual material after the front cover but not part of the book's content such as a foreword, a dedication, a table of contents and publisher data such as the book's edition or printing number and place of publication. Between the body copy and the back cover goes the end matter which would include any indices, sets of tables, diagrams, glossaries or lists of cited works (though an edited book with several authors usually places cited works at the end of each authored chapter). The inside back cover page, like that inside the front cover, is usually blank. The back cover is the usual place for the book's ISBN and maybe a photograph of the author(s)/ editor(s), perhaps with a short introduction to them. Also here often appear plot summaries, barcodes and excerpted reviews of the book. + +The body of the books is usually divided into parts, chapters, sections and sometimes subsections that are composed of at least a paragraph or more. + +Printing +Some books, particularly those with shorter runs (i.e. with fewer copies) will be printed on sheet-fed offset presses, but most books are now printed on web presses, which are fed by a continuous roll of paper, and can consequently print more copies in a shorter time. As the production line circulates, a complete "book" is collected together in one stack of pages, and another machine carries out the folding, pleating, and stitching of the pages into bundles of signatures (sections of pages) ready to go into the gathering line. The pages of a book are printed two at a time, not as one complete book. Excess numbers are printed to make up for any spoilage due to make-readies or test pages to assure final print quality. + +A make-ready is the preparatory work carried out by the pressmen to get the printing press up to the required quality of impression. Included in make-ready is the time taken to mount the plate onto the machine, clean up any mess from the previous job, and get the press up to speed. As soon as the pressman decides that the printing is correct, all the make-ready sheets will be discarded, and the press will start making books. Similar make readies take place in the folding and binding areas, each involving spoilage of paper. + +Binding +After the signatures are folded and gathered, they move into the bindery. In the middle of last century there were still many trade binders—stand-alone binding companies which did no printing, specializing in binding alone. At that time, because of the dominance of letterpress printing, typesetting and printing took place in one location, and binding in a different factory. When type was all metal, a typical book's worth of type would be bulky, fragile and heavy. The less it was moved in this condition the better: so printing would be carried out in the same location as the typesetting. Printed sheets on the other hand could easily be moved. Now, because of increasing computerization of preparing a book for the printer, the typesetting part of the job has flowed upstream, where it is done either by separately contracting companies working for the publisher, by the publishers themselves, or even by the authors. Mergers in the book manufacturing industry mean that it is now unusual to find a bindery which is not also involved in book printing (and vice versa). + +If the book is a hardback its path through the bindery will involve more points of activity than if it is a paperback. Unsewn binding is now increasingly common. The signatures of a book can also be held together by "Smyth sewing" using needles, "McCain sewing", using drilled holes often used in schoolbook binding, or "notch binding", where gashes about an inch long are made at intervals through the fold in the spine of each signature. The rest of the binding process is similar in all instances. Sewn and notch bound books can be bound as either hardbacks or paperbacks. + +Finishing + +"Making cases" happens off-line and prior to the book's arrival at the binding line. In the most basic case-making, two pieces of cardboard are placed onto a glued piece of cloth with a space between them into which is glued a thinner board cut to the width of the spine of the book. The overlapping edges of the cloth (about 5/8" all round) are folded over the boards, and pressed down to adhere. After case-making the stack of cases will go to the foil stamping area for adding decorations and type. + +Digital printing +Recent developments in book manufacturing include the development of digital printing. Book pages are printed, in much the same way as an office copier works, using toner rather than ink. Each book is printed in one pass, not as separate signatures. Digital printing has permitted the manufacture of much smaller quantities than offset, in part because of the absence of make readies and of spoilage. One might think of a web press as printing quantities over 2000, quantities from 250 to 2000 being printed on sheet-fed presses, and digital presses doing quantities below 250. These numbers are of course only approximate and will vary from supplier to supplier, and from book to book depending on its characteristics. Digital printing has opened up the possibility of print-on-demand, where no books are printed until after an order is received from a customer. + +Ebook + +In the 2000s, due to the rise in availability of affordable handheld computing devices, the opportunity to share texts through electronic means became an appealing option for media publishers. Thus, the "ebook" was made. The term ebook is a contraction of "electronic book"; which refers to a book-length publication in digital form. An ebook is usually made available through the internet, but also on CD-ROM and other forms. Ebooks may be read either via a computing device with an LED display such as a traditional computer, a smartphone, or a tablet computer; or by means of a portable e-ink display device known as an ebook reader, such as the Sony Reader, Barnes & Noble Nook, Kobo eReader, or the Amazon Kindle. Ebook readers attempt to mimic the experience of reading a print book by using the e-ink technology, since the displays on ebook readers are much less reflective. + +Audiobooks + +Audiobooks, or recordings of people reading books aloud, were first created in 1932 in the United States. The first audiobooks were created by the American Foundation for the Blind on vinyl records, where each side could hold 15 minutes of recording. The first recorded pieces were some of William Shakespeare's plays, the Constitution of the United States, and the novel As the Earth Turns by Gladys Hasty Carroll. Gradually over the course of the 20th century and with the dawn of cassette tapes and compact discs, audiobooks began to be sold by booksellers who often had dedicated sections. Publishers of books additionally created divisions within their companies dedicated to audiobooks. By the turn of the millennium, audiobooks were digitally distributed on devices designed around audiobooks, and audiobooks began to receive different narrators for different parts. Some companies, such as the Amazon subsidiary Audible, are tailored to work exclusively in audiobooks, and while their effectiveness is subject to wide debate, sales of audiobooks continue to skyrocket in the present day. + +Design + +Book design is the art of incorporating the content, style, format, design, and sequence of the various components of a book into a coherent whole. In the words of Jan Tschichold, book design "though largely forgotten today, methods and rules upon which it is impossible to improve have been developed over centuries. To produce perfect books these rules have to be brought back to life and applied." Richard Hendel describes book design as "an arcane subject" and refers to the need for a context to understand what that means. Many different creators can contribute to book design, including graphic designers, artists and editors. + +Sizes + +The size of a modern book is based on the printing area of a common flatbed press. The pages of type were arranged and clamped in a frame, so that when printed on a sheet of paper the full size of the press, the pages would be right side up and in order when the sheet was folded, and the folded edges trimmed. + +The most common book sizes are: + Quarto (4to): the sheet of paper is folded twice, forming four leaves (eight pages) approximately 11–13 inches (c. 30 cm) tall + Octavo (8vo): the most common size for current hardcover books. The sheet is folded three times into eight leaves (16 pages) up to inches (c. 23 cm) tall. + DuoDecimo (12mo): a size between 8vo and 16mo, up to inches (c. 18 cm) tall + Sextodecimo (16mo): the sheet is folded four times, forming 16 leaves (32 pages) up to inches (c. 15 cm) tall + +Sizes smaller than 16mo are: + 24mo: up to inches (c. 13 cm) tall. + 32mo: up to 5 inches (c. 12 cm) tall. + 48mo: up to 4 inches (c. 10 cm) tall. + 64mo: up to 3 inches (c. 8 cm) tall. + +Small books can be called booklets. + +Sizes larger than quarto are: + Folio: up to 15 inches (c. 38 cm) tall. + Elephant Folio: up to 23 inches (c. 58 cm) tall. + Atlas Folio: up to 25 inches (c. 63 cm) tall. + Double Elephant Folio: up to 50 inches (c. 127 cm) tall. + +The largest extant medieval manuscript in the world is Codex Gigas 92 × 50 × 22 cm. The world's largest book is made of stone and is in Kuthodaw Pagoda (Burma). + +Types + +By content + +A common separation by content are fiction and non-fiction books. This simple separation can be found in most collections, libraries, and bookstores. There are other types such as books of sheet music. + +Fiction +Many of the books published today are "fiction", meaning that they contain invented material, and are creative literature. Other literary forms such as poetry are included in the broad category. Most fiction is additionally categorized by literary form and genre. + +The novel is the most common form of fiction book. Novels are stories that typically feature a plot, setting, themes and characters. Stories and narrative are not restricted to any topic; a novel can be whimsical, serious or controversial. The novel has had a tremendous impact on entertainment and publishing markets. A novella is a term sometimes used for fiction prose typically between 17,500 and 40,000 words, and a novelette between 7,500 and 17,500. A short story may be any length up to 10,000 words, but these word lengths vary. + +Comic books or graphic novels are books in which the story is illustrated. The characters and narrators use speech or thought bubbles to express verbal language. + +Non-fiction + +Non-fiction books are in principle based on fact, on subjects such as history, politics, social and cultural issues, as well as autobiographies and memoirs. Nearly all academic literature is non-fiction. A reference book is a general type of non-fiction book which provides information as opposed to telling a story, essay, commentary, or otherwise supporting a point of view. + +An almanac is a very general reference book, usually one-volume, with lists of data and information on many topics. An encyclopedia is a book or set of books designed to have more in-depth articles on many topics. A book listing words, their etymology, meanings, and other information is called a dictionary. A book which is a collection of maps is an atlas. A more specific reference book with tables or lists of data and information about a certain topic, often intended for professional use, is often called a handbook. Books which try to list references and abstracts in a certain broad area may be called an index, such as Engineering Index, or abstracts such as chemical abstracts and biological abstracts. + +Books with technical information on how to do something or how to use some equipment are called instruction manuals. Other popular how-to books include cookbooks and home improvement books. + +Students typically store and carry textbooks and schoolbooks for study purposes. + +Unpublished +Many types of book are private, often filled in by the owner, for a variety of personal records. Elementary school pupils often use workbooks, which are published with spaces or blanks to be filled by them for study or homework. In US higher education, it is common for a student to take an exam using a blue book. + +There is a large set of books that are made only to write private ideas, notes, and accounts. These books are rarely published and are typically destroyed or remain private. Notebooks are blank papers to be written in by the user. Students and writers commonly use them for taking notes. Scientists and other researchers use lab notebooks to record their notes. They often feature spiral coil bindings at the edge so that pages may easily be torn out. + +Address books, phone books, and calendar/appointment books are commonly used on a daily basis for recording appointments, meetings and personal contact information. Books for recording periodic entries by the user, such as daily information about a journey, are called logbooks or logs. A similar book for writing the owner's daily private personal events, information, and ideas is called a diary or personal journal. Businesses use accounting books such as journals and ledgers to record financial data in a practice called bookkeeping (now usually held on computers rather than in hand-written form). + +Other +There are several other types of books which are not commonly found under this system. Albums are books for holding a group of items belonging to a particular theme, such as a set of photographs, card collections, and memorabilia. One common example is stamp albums, which are used by many hobbyists to protect and organize their collections of postage stamps. Such albums are often made using removable plastic pages held inside in a ringed binder or other similar holder. Picture books are books for children with pictures on every page and less text (or even no text). + +Hymnals are books with collections of musical hymns that can typically be found in churches. Prayerbooks or missals are books that contain written prayers and are commonly carried by monks, nuns, and other devoted followers or clergy. Lap books are a learning tool created by students. + +Decodable readers and leveling +A leveled book collection is a set of books organized in levels of difficulty from the easy books appropriate for an emergent reader to longer more complex books adequate for advanced readers. Decodable readers or books are a specialized type of leveled books that use decodable text only including controlled lists of words, sentences and stories consistent with the letters and phonics that have been taught to the emergent reader. New sounds and letters are added to higher level decodable books, as the level of instruction progresses, allowing for higher levels of accuracy, comprehension and fluency. + +By physical format + +Hardcover books have a stiff binding. Paperback books have cheaper, flexible covers which tend to be less durable. An alternative to paperback is the glossy cover, otherwise known as a dust cover, found on magazines, and comic books. Spiral-bound books are bound by spirals made of metal or plastic. Examples of spiral-bound books include teachers' manuals and puzzle books (crosswords, sudoku). + +Publishing is a process for producing pre-printed books, magazines, and newspapers for the reader/user to buy. + +Publishers may produce low-cost, pre-publication copies known as galleys or 'bound proofs' for promotional purposes, such as generating reviews in advance of publication. Galleys are usually made as cheaply as possible, since they are not intended for sale. + +Dummy books + +Dummy books (or faux books) are books that are designed to imitate a real book by appearance to deceive people, some books may be whole with empty pages, others may be hollow or in other cases, there may be a whole panel carved with spines which are then painted to look like books, titles of some books may also be fictitious. + +There are many reasons to have dummy books on display such as; to allude visitors of the vast wealth of information in their possession and to inflate the owner's appearance of wealth, to conceal something, for shop displays or for decorative purposes. + +In early 19th century at Gwrych Castle, North Wales, Lloyd Hesketh Bamford-Hesketh was known for his vast collection of books at his library, however, at the later part of that same century, the public became aware that parts of his library was a fabrication, dummy books were built and then locked behind glass doors to stop people from trying to access them, from this a proverb was born, "Like Hesky's library, all outside". + +Libraries + +Private or personal libraries made up of non-fiction and fiction books, (as opposed to the state or institutional records kept in archives) first appeared in classical Greece. In the ancient world, the maintaining of a library was usually (but not exclusively) the privilege of a wealthy individual. These libraries could have been either private or public, i.e. for people who were interested in using them. The difference from a modern public library lies in that they were usually not funded from public sources. It is estimated that in the city of Rome at the end of the 3rd century there were around 30 public libraries. Public libraries also existed in other cities of the ancient Mediterranean region (for example, Library of Alexandria). Later, in the Middle Ages, monasteries and universities also had libraries that could be accessible to the general public. Typically not the whole collection was available to the public; the books could not be borrowed and often were chained to reading stands to prevent theft. + +The beginning of the modern public library begins around 15th century when individuals started to donate books to towns. The growth of a public library system in the United States started in the late 19th century and was much helped by donations from Andrew Carnegie. This reflected classes in a society: the poor or the middle class had to access most books through a public library or by other means, while the rich could afford to have a private library built in their homes. In the United States the Boston Public Library 1852 Report of the Trustees established the justification for the public library as a tax-supported institution intended to extend educational opportunity and provide for general culture. + +The advent of paperback books in the 20th century led to an explosion of popular publishing. Paperback books made owning books affordable for many people. Paperback books often included works from genres that had previously been published mostly in pulp magazines. As a result of the low cost of such books and the spread of bookstores filled with them (in addition to the creation of a smaller market of extremely cheap used paperbacks), owning a private library ceased to be a status symbol for the rich. + +The development of libraries has prompted innovations to help store and organize books on shelves. In library and booksellers' catalogues, it is common to include an abbreviation such as "Crown 8vo" to indicate the paper size from which the book is made. When rows of books are lined on a book holder, bookends are sometimes needed to keep them from slanting. + +Identification and classification + +During the 20th century, librarians were concerned about keeping track of the many books being added yearly to the Gutenberg Galaxy. Through a global society called the International Federation of Library Associations and Institutions (IFLA), they devised a series of tools including the International Standard Bibliographic Description (ISBD). Each book is specified by an International Standard Book Number, or ISBN, which is unique to every edition of every book produced by participating publishers, worldwide. It is managed by the ISBN Society. An ISBN has four parts: the first part is the country code, the second the publisher code, and the third the title code. The last part is a check digit, and can take values from 0–9 and X (10). The EAN Barcodes numbers for books are derived from the ISBN by prefixing 978, for Bookland, and calculating a new check digit. + +Commercial publishers in industrialized countries generally assign ISBNs to their books, so buyers may presume that the ISBN is part of a total international system, with no exceptions. However, many government publishers, in industrial as well as developing countries, do not participate fully in the ISBN system, and publish books which do not have ISBNs. A large or public collection requires a catalogue. Codes called "call numbers" relate the books to the catalogue, and determine their locations on the shelves. Call numbers are based on a Library classification system. The call number is placed on the spine of the book, normally a short distance before the bottom, and inside. Institutional or national standards, such as ANSI/NISO Z39.41 – 1997, establish the correct way to place information (such as the title, or the name of the author) on book spines, and on "shelvable" book-like objects, such as containers for DVDs, video tapes and software. + +One of the earliest and most widely known systems of cataloguing books is the Dewey Decimal System. Another widely known system is the Library of Congress Classification system. Both systems are biased towards subjects which were well represented in US libraries when they were developed, and hence have problems handling new subjects, such as computing, or subjects relating to other cultures. Information about books and authors can be stored in databases like online general-interest book databases. Metadata, which means "data about data" is information about a book. Metadata about a book may include its title, ISBN or other classification number (see above), the names of contributors (author, editor, illustrator) and publisher, its date and size, the language of the text, its subject matter, etc. + +Classification systems + Bliss bibliographic classification (BC) + Chinese Library Classification (CLC) + Colon Classification + Dewey Decimal Classification (DDC) + Harvard-Yenching Classification + Library of Congress Classification (LCC) + New Classification Scheme for Chinese Libraries + Universal Decimal Classification (UDC) + +Uses +Aside from the primary purpose of reading them, books are also used for other ends: + A book can be an artistic artifact, a piece of art; this is sometimes known as an artists' book. + A book may be evaluated by a reader or professional writer to create a book review. + A book may be read by a group of people to use as a spark for social or academic discussion, as in a book club. + A book may be studied by students as the subject of a writing and analysis exercise in the form of a book report. + Books are sometimes used for their exterior appearance to decorate a room, such as a study. + +Marketing +Once the book is published, it is put on the market by distributors and bookstores. Meanwhile, its promotion comes from various media reports. Book marketing is governed by the law in many states. + +Secondary spread +In recent years, the book had a second life in the form of reading aloud. This is called public readings of published works, with the assistance of professional readers (often known actors) and in close collaboration with writers, publishers, booksellers, librarians, leaders of the literary world and artists. + +Many individual or collective practices exist to increase the number of readers of a book. Among them: + abandonment of books in public places, coupled or not with the use of the Internet, known as the bookcrossing; + provision of free books in third places, like bars or cafes; + itinerant or temporary libraries; + free public libraries in the area. + +Industry evolution +This form of the book chain has hardly changed since the eighteenth century, and has not always been this way. Thus, the author has asserted gradually with time, and the copyright dates only from the nineteenth century. For many centuries, especially before the invention of printing, each freely copied out books that passed through his hands, adding if desired his own comments. Similarly, bookseller and publisher jobs have emerged with the invention of printing, which made the book an industrial product, requiring structures of production and marketing. + +The invention of the Internet, e-readers, tablets, and projects like Wikipedia and Gutenberg, are likely to change the book industry for years to come. + +Paper and conservation + +Paper was first made in China as early as 200 BC, and reached Europe through Muslim territories. At first made of rags, the Industrial Revolution changed paper-making practices, allowing for paper to be made out of wood pulp. Papermaking in Europe began in the 11th century, although vellum was also common there as page material up until the beginning of the 16th century, vellum being the more expensive and durable option. Printers or publishers would often issue the same publication on both materials, to cater to more than one market. + +Paper made from wood pulp became popular in the early 20th century, because it was cheaper than linen or abaca cloth-based papers. Pulp-based paper made books less expensive to the general public. This paved the way for huge leaps in the rate of literacy in industrialised nations, and enabled the spread of information during the Second Industrial Revolution. + +Pulp paper, however, contains acid which eventually destroys the paper from within. Earlier techniques for making paper used limestone rollers, which neutralized the acid in the pulp. Books printed between 1850 and 1950 are primarily at risk; more recent books are often printed on acid-free or alkaline paper. Libraries today have to consider mass deacidification of their older collections in order to prevent decay. + +Stability of the climate is critical to the long-term preservation of paper and book material. Good air circulation is important to keep fluctuation in climate stable. The HVAC system should be up to date and functioning efficiently. Light is detrimental to collections. Therefore, care should be given to the collections by implementing light control. General housekeeping issues can be addressed, including pest control. In addition to these helpful solutions, a library must also make an effort to be prepared if a disaster occurs, one that they cannot control. Time and effort should be given to create a concise and effective disaster plan to counteract any damage incurred through "acts of God", therefore an emergency management plan should be in place. + +See also + + Outline of books + Alphabet book + Artist's book + Audiobook + Bibliodiversity + Book burning + Booksellers + Lists of books + Miniature book + Open access book + Society for the History of Authorship, Reading and Publishing (SHARP) + +Citations + +Bibliography + "Book", in International Encyclopedia of Information and Library Science ("IEILS"), Editors: John Feather, Paul Sturges, 2003, Routledge, + +Further reading + Tim Parks (August 2017), "The Books We Don't Understand", The New York Review of Books + +External links + + Information on Old Books, Smithsonian Libraries + "Manuscripts, Books, and Maps: The Printing Press and a Changing World" + + +Documents +Paper products +Media formats +The B-52 is an American strategic bomber aircraft. + +B-52 or B52 may also refer to: + The B-52's, an American new wave band + The B-52's (album) + B52 (New York City bus), a bus line in Brooklyn, New York + B52 (chess opening), a chess opening based on the Sicilian Defence + B-52 (cocktail) + B-52 (hairstyle) or beehive, a hairstyle + B-52 Memorial Park, a park within the Orlando International Airport, Florida + Volvo B52 engine, a group of Volvo engines + Nora B-52, a Serbian self-propelled howitzer + HLA-B52, an HLA-B serotype + Bundesstraße 52, a federal highway in Germany + B52, route number for Kings Highway in Australia + B-52, a coded reference to Mao Zedong in Project 571 + B-52, a pennant number of the Argentinian fast transport ship ARA Hércules (B-52) +Bal Keshav Thackeray (; 23 January 1926 – 17 November 2012) also known as Balasaheb Thackeray, was an Indian politician who founded the Shiv Sena, a right-wing pro-Marathi and Hindu nationalist party active mainly in the state of Maharashtra. + +Thackeray began his professional career as a cartoonist with the English-language daily, The Free Press Journal in Bombay, but he left the paper in 1960 to form his own political weekly, Marmik. His political philosophy was largely shaped by his father Keshav Sitaram Thackeray, a leading figure in the Samyukta Maharashtra (United Maharashtra) movement, which advocated the creation of a separate linguistic state for Marathi speakers. Through Marmik, Bal Thackeray campaigned against the growing influence of non-Marathis in Mumbai. + +He had a large political influence in the state, especially in Mumbai. An inquiry report by human rights watch, submitted to the government found that Thackeray and Chief Minister of Maharashtra Manohar Joshi incited members of the Shiv Sena to commit violence against Muslims during the 1992–1993 Bombay riots. + +In the late 1960s and early 1970s, Thackeray built the Shiv Sena with help of Madhav Mehere chief attorney for trade union of India, Babasaheb Purandare, historian for Govt of Maharastra and Madhav Deshpande Head Accountant for Shiv Sena, these three individuals to a large extent were responsible for the success of Shiv Sena and stability of politics in Mumbai till 2000 to ensure it grows into an economic power center. Thackeray was also the founder of the Marathi-language newspaper Saamana. After the riots of 1992–93, he and his party took a Hindutva stance. In 1999, Thackeray was banned from voting and contesting in any election for six years on the recommendations of the Election Commission for indulging in seeking votes in the name of religion. Thackeray was arrested multiple times and spent a brief stint in prison, but he never faced any major legal repercussions. Upon his death, he was accorded a state funeral, at which many mourners were present. Thackeray did not hold any official positions, and he was never formally elected as the leader of his party. + +Early life + +Thackeray was born on 23 January 1926 in Pune, the son of Prabodhankar Thackeray and his wife Ramabai Thackeray. The family belongs to the Marathi Hindu Chandraseniya Kayastha Prabhu community. His father Keshav was an admirer of India-born British writer William Makepeace Thackeray, and changed his own surname from Panvelkar to "Thackeray" an Anglicised version of their ancestral surname "Thakre". + +Bal's father was a journalist and cartoonist by profession, he was also a social activist and a writer who was involved in a Samyukta Maharashtra Samiti, which advocated the creation of a separate linguistic state for Marathi speakers. He also started a magazine named Prabodhan, where he promoted Hindu philosophies and nationalistic ideals to revive Hindutva in society. This proved to highly influential in shaping Bal Thackeray's political views. + +Career +Thackeray began his career as a cartoonist in the Free Press Journal in Mumbai. His cartoons were also published in the Sunday edition of The Times of India. After Thackeray's differences with the Free Press Journal, he and four or five people, including politician George Fernandes, left the paper and started their own daily, News Day. The paper survived for one or two months. In 1960, he launched the cartoon weekly Marmik with his brother Srikant. It focused on issues of common "Marathi Manoos" (Marathi, or Marathi-speaking, people) including unemployment, immigration and the retrenchment of Marathi workers. Its office in Ranade Road became the rallying point for Marathi youth. Bal Thackeray later stated that it was "not just a cartoon weekly but also the prime reason for the birth and growth of the Sena". It was the issue of Marmik on 5 June 1966 which first announced the launch of membership for the Shiv Sena. + +Politics + +1966–1998 +The success of Marmik prompted Thackeray to form the Shiv Sena on 19 June 1966. The name Shiv Sena (Shivaji's Army) is a reference to the 17th century Maratha Emperor Shivaji. Initially, Thackeray said it was not a political party but an army of Shivaji Maharaj, inclined to fight for the Marathi manoos (person). It demanded that native speakers of the state's local language Marathi (the "sons of the soil" movement) be given preferential treatment in private and public sector jobs. The early objective of the Shiv Sena was to ensure their job security competing against South Indians and Gujaratis. In its 1966 party manifesto, Thackeray primarily blamed south Indians. In Marmik, Thackeray published a list of corporate officials from a local directory, many being south Indians, citing it as proof that Maharashtrians were being discriminated against. + +His party grew in the next ten years. Senior leaders such as Babasaheb Purandare, chief attorney for Trade Union of Maharashtra Madhav Mehere joined the party and chartered accountant Madhav Gajanan Deshpande backed various aspects of the party operations. In 1969, Thackeray and Manohar Joshi were jailed after participating in a protest demanding the merger of Karwar, Belgaum and Nipani regions in Maharashtra. During the 1970s, it did not succeed in the local elections and it was active mainly in Mumbai, compared to the rest of the state. The party set up local branch offices and settled disputes, complaints against the government. It later started violent tactics with attacks against rival parties, migrants and the media; the party agitated by destroying public and private property. Thackeray publicly supported Indira Gandhi during the 1975 Emergency to avoid getting arrested; Thackeray supported the Congress party numerous times. + +Dr. Hemchandra Gupte, Mayor of Mumbai and the former family physician and confidant of Thackeray, left Shiv Sena in 1976 citing the emphasis given to money, violence committed by the Shiv Sena members, and Thackeray's support for Indira Gandhi and the 1975 emergency. + +Politically, the Shiv Sena was anti-communist, and wrested control of trade unions in Mumbai from the Communist Party of India (CPI). Local unemployed youth from the declining textile industry joined the party and it further expanded because of Marathi migrants from the Konkan region. By the 1980s, it became a threat to the ruling Congress party which had initially encouraged it because of it rivalling the CPI. In 1989, the Sena's newspaper Saamna was launched by Thackeray. Because of Thackeray being against the Mandal Commission report, his close aide Chhagan Bhujbal left the party in 1991. Following the 1992 Bombay riots, Thackeray took stances viewed as anti-Muslim and based on Hindutva. Shiv Sena later allied itself with the Bharatiya Janata Party (BJP). The BJP-Shiv Sena alliance won the 1995 Maharashtra State Assembly elections and were in power from 1995 to 1999. Thackeray declared himself to be the "remote control" chief minister. + +Thackeray and the Chief Minister Manohar Joshi were explicitly named for inciting the Shivsainiks for violence against Muslims during the 1992–1993 riots in an inquiry ordered by the government of India, the Srikrishna Commission Report. + +Thackeray had influence in the film industry. His party workers agitated against films he found controversial and would disrupt film screenings, causing losses. Bombay, a 1995 film on the riots, was opposed by them. + +1999–2012 +On 28 July 1999, Thackeray was banned from voting and contesting in any election for six years from 11 December 1999 till 10 December 2005 on the recommendations of the Election Commission for indulging in corrupt practice by seeking votes in the name of religion. In 2000, he was arrested for his role in the riots but was released because the statute of limitations expired. In 2002, Thackeray issued a call to form Hindu suicide bomber squads to take on the menace of terrorism. In response, the Maharashtra government registered a case against him for inciting enmity between different groups. At least two organisations founded and managed by retired Indian Army officers, Lt Col Jayant Rao Chitale and Lt Gen. P.N. Hoon (former commander-in-chief of the Western Command), responded to the call with such statements as not allowing Pakistanis to work in India due to accusations against Pakistan for supporting attacks in India by militants. After the six-year voting ban on Thackeray was lifted in 2005, he voted for the first time in the 2007 BMC elections. Eight or nine cases against Thackeray and Saamna for inflammatory writings were not investigated by the government. + +Thackeray said that the Shiv Sena had helped the Marathi people in Mumbai, especially in the public sector. Thackeray believed that Hindus must be organised to struggle against those who oppose their identity and religion. Opposition leftist parties alleged that the Shiv Sena has done little to solve the problem of unemployment facing a large proportion of Maharashtrian youth during its tenure, in contradiction to its ideological foundation of 'sons of the soil.' + +In 2006, Thackeray's nephew Raj Thackeray broke away from Shiv Sena to form the Maharashtra Navnirman Sena (MNS) during Thackeray's retirement and appointment of his son, Uddhav rather than Raj as the leader of Shiv Sena. Narayan Rane also quit around that time. + +The Sena acted as a "moral police" and opposed Valentine's Day celebrations. On 14 February 2006, Thackeray condemned and apologised for the violent attacks by its Shiv Sainiks on a private celebration in Mumbai. "It is said that women were beaten up in the Nallasopara incident. If that really happened, then it is a symbol of cowardice. I have always instructed Shiv Sainiks that in any situation women should not be humiliated and harassed." Thackeray and the Shiv Sena remained opposed to it, although they indicated support for an Indian alternative. + +In 2007, he was briefly arrested and let out on bail after referring to Muslims as 'Green Poison' during a Shiv Sena rally. + +On 27 March 2008, in protest to Thackeray's editorial, leaders of Shiv Sena in Delhi resigned, citing its outrageous conduct towards non-Marathis in Maharashtra and announced that they would form a separate party. Addressing a press conference, Shiv Sena's North India chief Jai Bhagwan Goyal said the decision to leave the party was taken because of the partial attitude of the party high command towards Maharashtrians. Goyal further said that Shiv Sena is no different from Khalistan and Jammu and Kashmir militant groups which are trying to create a rift between people along regional lines. The main aim of these forces is to split our country. Like the Maharashtra Navnirman Sena, the Shiv Sena too has demeaned North Indians and treated them inhumanely. + +Political views +Thackeray was criticised for his praise of Adolf Hitler. He was quoted by Asiaweek as saying: "I am a great admirer of Hitler, and I am not ashamed to say so! I do not say that I agree with all the methods he employed, but he was a wonderful organiser and orator, and I feel that he and I have several things in common...What India really needs is a dictator who will rule benevolently, but with an iron hand." In a 1993 interview, Thackeray stated, "There is nothing wrong if Muslims are treated as Jews were in Nazi Germany." In another 1992 interview, Thackeray stated, "If you take Mein Kampf and if you remove the word 'Jew' and put in the word 'Muslim', that is what I believe in". Indian Express published an interview on 29 January 2007: "Hitler did very cruel and ugly things. But he was an artist, I love him [for that]. He had the power to carry the whole nation, the mob with him. You have to think what magic he had. He was a miracle...The killing of Jews was wrong. But the good part about Hitler was that he was an artist. He was a daredevil. He had good qualities and bad. I may also have good qualities and bad ones." + +Thackeray also declared that he was not against every Muslim, but only those who reside in this country but do not obey the laws of the land...I consider such people [to be] traitors. The Shiv Sena is viewed by the media as being anti-Muslim, though Shiv sena members officially reject this accusation. When explaining his views on Hindutva, he conflated Islam with violence and called on Hindus to fight terrorism and fight Islam. In an interview with Suketu Mehta, he called for the mass expulsion of illegal Bangladeshi Muslim migrants from India and for a visa system to enter Mumbai, the Indian National Congress state government had earlier during the Indira Gandhi declared national emergency considered a similar measure. + +He told India Today "[Muslims] are spreading like a cancer and should be operated on like a cancer. The country...should be saved from the Muslims and the police should support them [Hindu Maha Sangh] in their struggle just like the police in Punjab were sympathetic to the Khalistanis." However, in an interview in 1998, he said that his stance had changed on many issues that the Shiv Sena had with Muslims, particularly regarding the Babri Mosque or Ram Janmabhoomi issue: "We must look after the Muslims and treat them as part of us." He also expressed admiration for Muslims in Mumbai in the wake of the 11 July 2006 Mumbai train bombings perpetrated by Islamic fundamentalists. In response to threats made by Abu Azmi, a leader of the Samajwadi Party, that accusations of terrorism directed at Indian Muslims would bring about communal strife, Thackeray said that the unity of Mumbaikars (residents of Mumbai) in the wake of the attacks was a slap to fanatics of Samajwadi Party leader Abu Asim Azmi and that Thackeray salute[s] those Muslims who participated in the two minutes' silence on 18 July to mourn the blast victims. Again in 2008 he wrote: "Islamic terrorism is growing and Hindu terrorism is the only way to counter it. We need suicide bomb squads to protect India and Hindus." He also reiterated a desire for Hindus to unite across linguistic barriers to see a Hindustan for Hindus and to bring Islam in this country down to its knees. + +In 2008, following agitation against Biharis and other north Indians travelling to Maharashtra to take civil service examinations for the Indian Railways due to an overlimit of the quota in their home provinces, Thackeray also said of Bihari MPs that they were spitting in the same plate from which they ate when they criticised Mumbaikars and Maharashtrians. He wrote: "They are trying to add fuel to the fire that has been extinguished, by saying that Mumbaikars have rotten brains." He also criticised Chhath Puja, a holiday celebrated by Biharis and those from eastern Uttar Pradesh, which occurs on six days of the Hindu month of Kartik. He said that it was not a real holiday. This was reportedly a response to MPs from Bihar who had disrupted the proceedings of the Lok Sabha in protest to the attacks on North Indians. Bihar Chief Minister Nitish Kumar, upset with the remarks, called on the prime minister and the central government to intervene in the matter. A Saamna editorial prompted at least 16 MPs from Bihar and Uttar Pradesh, belonging to the Rashtriya Janata Dal, Janata Dal (United), Samajwadi Party and the Indian National Congress, to give notice for breach of privilege proceedings against Thackeray. After the matter was raised in the Lok Sabha, Speaker Somnath Chatterjee said: "If anybody has made any comment on our members' functioning in the conduct of business in the House, not only do we treat that with the contempt that it deserves, but also any action that may be necessary will be taken according to procedure and well established norms. Nobody will be spared.'" + +In 2009, he criticised Indian cricketer Sachin Tendulkar, a "Marathi icon", for saying he was an Indian before he was a Maharashtrian. + +Opposition to Caste Based Reservations +Thackeray firmly opposed caste based reservation and said - "There are only two castes in the world, the rich are rich and the poor is poor, make the poor rich but don't make the rich poor. Besides these two castes I don't believe in any other casteism." +The Bhartiya Janata Party (BJP) supported caste based reservations based on the Mandal commission. Thackarey, despite being warned that opposition to the reservations would be politically suicidal for the Shiv Sena party, opposed the BJP over this issue and said he would initiate divorce proceedings against the BJP if the BJP supported caste based reservations. This also led to his conflict with Chhagan Bhujbal, an OBC, who later left the Shiv Sena. + +Views on Vinayak Damodar Savarkar +Thackeray defended Veer Savarkar against criticism and praised him as a great leader. In 2002, when President A. P. J. Abdul Kalam unveiled a portrait of Savarkar in the presence of Prime Minister Atal Bihari Vajpayee, the Congress Party opposed the unveiling of the portrait and boycotted the function. Thackeray criticised the opposition and said, "Who is [Congress president and Leader of the Opposition] Sonia Gandhi to object to the portrait? What relation does she have with the country? How much does she know about the history and culture of India?". Years later, when Congress General Secretary Digvijaya Singh made a statement that Savarkar was the first to suggest the two-nation theory that led to the partition, Thackeray defended Savarkar and accused Singh of distorting history. + +Support for Kashmiri Pandits +In 1990, Bal Thackeray got seats reserved in engineering colleges for the children of Kashmiri Pandits in Maharashtra. He was one of the first persons to help them after which Punjab also followed suit. At a meeting with them he supported the idea that the Kashmiri Pandits could be armed for their self-defence against Jihadis. + +Personal life +Thackeray was married to Meena Thackeray (née Sarla Vaidya) on 13 June 1948 and had three sons, oldest son Bindumadhav, middle son Jaidev, and youngest son Uddhav. Meena died in 1995 and Bindumadhav died the following year in a car accident. Bal was the eldest of eight siblings, three among them being brothers Shrikant Thackeray (father of Raj Thackeray) and Ramesh Thackeray, and five sisters (Sanjeevani Karandikar, Prabhavati (Pama) Tipnis, Malati (Sudha) Sule, Sarla Gadkari and Susheela Gupte). + +Raj is his brother Shrikant's son. Despite Raj's breakaway from the main party, Raj continues to maintain that Thackeray was his ideologue and relations between them improved during Thackeray's final years. Raj broke away from Shiv Sena to form his own political party called the Maharashtra Navnirman Sena. + +Sanjeevani Karandikar is Bal Thackeray's sister. + +Thackeray drew cartoons for the Free Press Journal, the Times of India and Marmik besides contributing to Saamna till 2012. He cited the New Zealander cartoonist David Low as his inspiration. + +Death + +Thackeray died on 17 November 2012, of cardiac arrest. Mumbai came to a virtual halt immediately as the news broke out about his death, with shops and commercial establishments shutting down. The entire state of Maharashtra was put on high alert. The police appealed for calm and 20,000 Mumbai police officers, 15 units of the State Reserve Police Force and three contingents of the Rapid Action Force were deployed. It was reported that Shiv Sena workers forced shops to close down in some areas. The then Prime Minister Manmohan Singh called for calm in the city and praised Thackeray's "strong leadership", while there were also statements of praise and condolences from other senior politicians such as the then-Gujarat Chief Minister Narendra Modi and the BJP leader and MP (Former Deputy Prime Minister of India), L. K. Advani. + +He was accorded a state funeral at Shivaji Park, which generated some controversy and resulted from demands made by Shiv Sena. It was the first public funeral in the city since that of Bal Gangadhar Tilak in 1920. Thackeray's body was moved to the park on 18 November. Many mourners attended his funeral, although there were no official figures. The range reported in media sources varied from around 1 million, to 1.5 million and as many as nearly 2 million. His cremation took place the next day, where his son Uddhav lit the pyre. Among those present at his cremation were senior representatives of the Maharashtra government and the event was broadcast live on national television channels. The Parliament of India opened for its winter session on 21 November 2012. Thackeray was the only non-member to be noted in its traditional list of obituaries. He is one of few people to have been recorded thus without being a member of either the Lok Sabha or the Rajya Sabha. Despite having not held any official position, he was given the 21-gun salute, which was again a rare honour. Both houses of Bihar Assembly also paid tribute. The funeral expenses created further controversies when media reports claimed that the BMC had used taxpayers' money. In response to these reports, the party later sent a cheque of Rs. 500,000 to the corporation. + +The Hindu, in an editorial, said regarding the shutdown that "Thackeray’s legion of followers raised him to the status of a demigod who could force an entire State to shut down with the mere threat of violence". Following his death, police arrested a 21-year-old woman who posted a Facebook comment against him, as well as her friend who "liked" the comment. Shiv Sena members also vandalised the clinic owned by the woman's relative. + +Legacy +Thackeray was called Hindu Hriday Samrat ("Emperor of Hindu Hearts") by his supporters. His yearly address at Shivaji Park was popular among his followers. In 2012, he instead gave a video-taped speech and urged his followers "to give the same love and affection to his son and political heir Uddhav as they had given him". Thackeray was known to convert popular sentiment into votes, getting into controversies and making no apologies for it though his son has tried to tone down the party's stance after his death. He was known for his inflammatory writings, was seen as a good orator who used cruel humour to engage his audience. He had a large political influence throughout the state, especially in Mumbai. His party never had any formal internal elections nor was he ever formally elected as its chief at any point. Gyan Prakash said, "Of course, the Samyukta Maharashtra Movement had mobilized Marathi speakers as a political entity, but it was Thackeray who successfully deployed it as an anti-immigrant, populist force." +He inspired Baliram Kashyap the leader of Bastar who often regarded as the Thackeray of Bastar. + +A memorial for him was proposed at Shivaji Park but legal issues and opposition from local residents continue to delay it. + +Thackeray is satirised in Salman Rushdie's 1995 novel The Moor's Last Sigh as 'Raman Fielding'. The book was banned by the Maharashtra state government. Suketu Mehta interviewed Thackeray in his critically acclaimed, Pulitzer-nominated, non-fiction 2004 book Maximum City. Thackeray previewed director Ram Gopal Verma's film Sarkar, which is loosely based on him, released in 2005. The 2011 documentary Jai Bhim Comrade depicted a speech by Thackeray at a public rally, in which he articulated "genocidal sentiments" about Muslims, stating that they were the "species to be exterminated." The documentary followed this by showing several Dalit leaders criticising Thackeray for his beliefs. + +In popular culture +A Bollywood biopic titled Thackeray, starring Nawazuddin Siddiqui and written by Shiv Sena politician Sanjay Raut was released on 25 January 2019. + +Makarand Padhye played Balasaheb Thakeray in the 2022 marathi film Dharmaveer based on the life of Shivsena politician Anand Dighe. + +See also + + Thackeray family + Prabodhankar Thackeray + Uddhav Thackeray + Shiv Sena + Marmik + +Notes + +References + +Further reading + +External links + + + + + + + +1926 births +2012 deaths +Indian anti-communists +Shiv Sena politicians +Politicians from Mumbai +Indian political party founders +Marathi-language writers +Indian editorial cartoonists +Marathi politicians +Anti-Bihari sentiment +Indian Hindus +Indian far-right politicians +20th-century Indian politicians +Thackeray family +Indian Hindu religious leaders +Hindu religious leaders +BSE may refer to: + +Medicine + Bovine spongiform encephalopathy, also known as mad cow disease, a neurodegenerative disease of cattle + Breast self-examination + +Stock exchanges + Bahrain Stock Exchange, Bahrain + Baku Stock Exchange, Azerbaijan + Barbados Stock Exchange + Beijing Stock Exchange, China + Bombay Stock Exchange, Mumbai, India + Boston Stock Exchange, Massachusetts, US + Botswana Stock Exchange in Gaborone, Botswana + Budapest Stock Exchange, Hungary + Bulgarian Stock Exchange – Sofia, BSE-Sofia + +Other uses + Blueprint for a Safer Economy, California classification of safe practices within a lockdown economy + Britain Stronger in Europe, a lobbying group + Board of Secondary Education, Odisha, India + Biological systems engineering + Bury St Edmunds railway station (station code), Suffolk, England + Backscattered electron (see scanning electron microscope) + Blender Stack Exchange, a Q&A site for the Blender 3D software + BSE (satellite), a Japanese satellite + Bachelor of Science in Engineering, an undergraduate academic degree awarded to a student after 3-5 years of studying engineering at a university or college + Black Sun Empire, a Dutch drum and bass group + Bethe–Salpeter equation, an equation in quantum field theory + Bendigo South East College, a secondary school in Victoria, Australia + Banco de Seguros del Estado, a Uruguayan state-owned insurance company + Sematan Airport (IATA code: BSE), an airport in Sarawak, Malaysia + +See also + Creutzfeldt–Jakob disease, sometimes called a human form of bovine spongiform encephalopathy +Bille August (born 9 November 1948) is a Danish director, screenwriter, and cinematographer of film and television.

It is located in the southern part of the Pelagonia valley, surrounded by the Baba, Nidže, and Kajmakčalan mountain ranges, north of the Medžitlija-Níki border crossing with Greece. The city stands at an important junction connecting the south of the Adriatic Sea region with the Aegean Sea and Central Europe, and it is an administrative, cultural, industrial, commercial, and educational centre. It has been known since the Ottoman period as the "City of Consuls", since many European countries had consulates in Bitola. + +Bitola, known during the Ottoman Empire as Manastır or Monastir, is one of the oldest cities in North Macedonia. It was founded as Heraclea Lyncestis in the middle of the 4th century BC by Philip II of Macedon. The city was the last capital of the First Bulgarian Empire (1015-1018) and the last capital of Ottoman Rumelia, from 1836 to 1867. According to the 2002 census, Bitola is the second-largest city in the country, after the capital Skopje. Bitola is also the seat of the Bitola Municipality. + +Etymology +The name Bitola is derived from the Old Church Slavonic word (, meaning "monastery, cloister"), literally "abode," as the city was formerly noted for its monastery. When the meaning of the name was no longer understood, it lost its prefix "o-". The name Bitola is mentioned in the Bitola inscription, related to the old city fortress built in 1015 during the ruling of Gavril Radomir of Bulgaria (1014–1015) when Bitola served as capital of the First Bulgarian Empire. Modern Slavic variants include the Macedonian (), the Serbian () and Bulgarian (). In Byzantine times, the name was Hellenized to () or (), hence the names Butella used by William of Tyre and Butili by the Arab geographer al-Idrisi. + +The Modern Greek name for the city (, ), also meaning "monastery", is a calque of the Slavic name. The Turkish name () is derived from the Greek name, as is the Albanian name (), and the Ladino name ( ). The Aromanian name, or alternatively, , is derived from the same root as the Macedonian name. + +Geography +Bitola is located in the southwestern part of North Macedonia. The Dragor River flows through the city. Bitola lies at an elevation of 615 metres above sea level, at the foot of Baba Mountain. Its magnificent Pelister mountain (2,601 m) is a national park with exquisite flora and fauna, among which is the rarest species of pine, known as Macedonian pine or pinus peuce. It is also the location of a well-known ski resort. + +Covering an area of . and with a population of 122,173 (1991), Bitola is an important industrial, agricultural, commercial, educational and cultural centre. It represents an important junction that connects the Adriatic Sea to the south with the Aegean Sea and Central Europe. + +Climate +Bitola has a mildly continental climate typical of the Pelagonija region, experiencing very warm and dry summers, and cold and snowy winters. The Köppen climate classification for this climate is Cfb, which would be an oceanic climate, going by the original threshold. + +History + +Prehistory +There are a number of prehistoric archaeological sites around Bitola. The earliest evidence of organized human settlements are the archaeological sites from the early Neolithic period, among which the most important are the tells of Veluška Tumba and Bara Tumba near the village of Porodin, first inhabited around 6000 BC. + +Ancient and early Byzantine periods +The region of Bitola was known as Lynkestis in antiquity, a region that became part of Upper Macedonia, and was ruled by semi-independent chieftains until the later Argead rulers of Macedon. The tribes of Lynkestis were known as Lynkestai. According to Nicholas Hammond, they were a Greek tribe belonging to the Molossian group of the Epirotes. There are important metal artifacts from the ancient period at the necropolis of Crkvište near the village of Beranci. A golden earring dating from the 4th century BC is depicted on the obverse of the Macedonian 10-denar banknote, issued in 1996. + +Heraclea Lyncestis ( - City of Hercules upon the Land of the Lynx) was an important settlement from the Hellenistic period till the early Middle Ages. It was founded by Philip II of Macedon by the middle of the 4th century BC, and named after the Greek hero Heracles. With its strategic location, it became a prosperous city. The Romans conquered this part of Macedon in 148 BC and destroyed the political power of the city. However, its prosperity continued mainly due to the Roman Via Egnatia road which passed near the city. A number of archaeological monuments from the Roman period can be seen today in Heraclea, including a portico, thermae (baths), a theater. The theatre was once capable of housing an audience of around 2,500 people. + +In the early Byzantine period (4th to 6th centuries AD) Heraclea became an important episcopal centre. Some of its bishops were mentioned in the acts of the first Church Councils, including Bishop Evagrius of Heraclea in the Acts of the Sardica Council of 343. The city walls, a number of Early Christian basilicas, the bishop's residence, and a lavish city fountain are some of the remains of this period. The floors in the three naves of the Great Basilica are covered with mosaics with a very rich floral and figurative iconography; these well preserved mosaics are often regarded as one of the finest examples of the early Christian art in the region. During the 4th and 6th centuries, the names of other bishops from Heraclea were recorded. The city was sacked by Ostrogothic forces, commanded by Theodoric the Great in 472 AD and, despite a large gift to him from the city's bishop, it was sacked again in 479. It was restored in the late 5th and early 6th centuries. However, in the late 6th century the city suffered successive attacks by various tribes, and eventually the region was settled by the early Slavic peoples. Its imperial buildings fell into disrepair and the city gradually declined to a small settlement, and survived as such until around the 11th century AD. + +Middle Ages +In the 6th and 7th centuries, the region around Bitola experienced a demographic shift as more and more Slavic tribes settled in the area. In place of the deserted theater, several houses were built during that time. The Slavs also built a fortress around their settlement. Bitola was a part of the First Bulgarian Empire from the middle of the 8th to the early 11th centuries, after which it again became part of the Byzantine Empire, and in turn was briefly part of the Serbian Empire during the 14th century. Arguably, a number of monasteries and churches were built in and around the city during the Medieval period (hence its other name Manastir). + +In the 10th century, Bitola came under the rule of tsar Samuel of Bulgaria. He built a castle in the town, later used by his successor Gavril Radomir of Bulgaria. The town is mentioned in several medieval sources. John Skylitzes's 11th-century chronicle mentions that Emperor Basil II burned Gavril's castle in Bitola, when passing through and ravaging Pelagonia. The second chrysobull (1019) of Basil II mentioned that the Bishop of Bitola depended on the Archbishopric of Ohrid. During the reign of Samuil, the city was the seat of the Bitola Bishopric. In many medieval sources, especially Western, the name Pelagonia was synonymous with the Bitola Bishopric. According to some sources, Bitola was known as Heraclea since what once was the Heraclea Bishopric later became the Pelagonian Metropolitan's Diocese. In 1015, Tsar Gavril Radomir was killed by his cousin Ivan Vladislav, who then declared himself tsar and rebuilt the city's fortress. To commemorate the occasion, a stone inscription written in the Cyrillic alphabet was set in the fortress; in it the Slavic name of the city is mentioned: Bitol. + +During the battle of Bitola in 1015 between a Bulgarian army under the command of the voivode Ivats and a Byzantine army led by the strategos George Gonitsiates, the Bulgarians were victorious and the Byzantine Emperor Basil II had to retreat from the Bulgarian capital Ohrid, whose outer walls were by that time already breached by the Bulgarians. Afterwards Ivan Vladislav moved the capital from Ohrid to Bitola, where he re-erected the fortress. However, the Bulgarian victory only postponed the fall of Bulgaria to Byzantine rule in 1018. + +As a military, political and religious center, Bitola played a very important role in the life of the medieval society in the region, prior to the Ottoman conquest in the mid-14th century. On the eve of the Ottoman conquest, Bitola (Monastir in Ottoman Turkish) experienced great growth with its well-established trading links all over the Balkan Peninsula, especially with big economic centers like Constantinople, Thessalonica, Ragusa and Tarnovo. Caravans carrying various goods came and went from Bitola. + +Ottoman rule + +From 1382 to 1912, Bitola was part of the Ottoman Empire, at which time it was called Monastir. Fierce battles took place near the city during the Ottoman conquest. Ottoman rule was completely established after the death of Prince Marko in 1395 when the Ottoman Empire established the Sanjak of Ohrid as a part of the Rumelia Eyalet and one of the earliest established sanjaks in Europe. Before it became part of the Ottoman Empire in 1395 Bitola was part of the realm of Prince Marko. Initially its county town was Bitola and later it was Ohrid, so it was sometimes referred to as the Sanjak of Monastir and sometimes as the Sanjak of Bitola. + +After the Austro-Ottoman wars, the trade development and the overall prosperity of the city declined. But in the late 19th century, it again became the second-largest city in the wider southern Balkan region after Thessaloniki. + +Between 1815 and 1822, the town was ruled by the Albanian Ali Pasha as part of the Pashalik of Yanina. + +During the Great Eastern Crisis, the local Bulgarian movement of the day was defeated when armed Bulgarian groups were repelled by the League of Prizren, an Albanian organisation opposing Bulgarian geopolitical aims in areas like Bitola that contained an Albanian population. Nevertheless, in April 1881, an Ottoman army captured Prizren and suppressed the League's rebellion. + +In 1874, Manastır became the center of Monastir Vilayet which included the sanjaks of Debra, Serfidze, Elbasan, Manastır (Bitola), Görice and the towns of Kırcaova, Pirlepe, Florina, Kesriye and Grevena. + +Traditionally a strong trading center, Bitola was also known as "the city of the consuls". In the final period of Ottoman rule (1878–1912), Bitola had consulates from twelve countries. During the same period, there were a number of prestigious schools in the city, including a military academy that, among others, was attended by the Turkish reformer Mustafa Kemal Atatürk. In 1883, there were 19 schools in Monastir, of which 11 were Greek, 5 were Bulgarian and 3 were Romanian. In Bitola, besides the schools where Ottomanism and Turkism flourished in the 19th century, schools of various nations were also opened. These institutions, which were very effective in increasing the education level and the rate of literacy, caused the formation of a circle of intellectuals in Bitola. Bitola was also the headquarters of many cultural organizations at that time. + +In 1894, Manastır was connected with Thessaloniki by train. The first motion picture made in the Balkans was produced by the Aromanian Manakis brothers in Manastır in 1903. In their honour, the annual Manaki Brothers International Cinematographers Film Festival is held in Bitola since 1979. + +In November 1905, the Secret Committee for the Liberation of Albania, a secret organization formed to fight for the liberation of Albania from the Ottoman Empire, was founded by Bajo Topulli and other Albanian nationalists and intellectuals. Three years later, the Congress of Manastir of 1908, which standardized the modern Albanian alphabet, was held in the city. The congress was held at the house of Fehim Zavalani. Mit'hat Frashëri was chairman of the congress. The participants in the Congress were prominent figures from the cultural and political life of Albanian-inhabited territories in the Balkans, and the Albanian diaspora. + +Ilinden Uprising + +The Bitola region was a stronghold of the Ilinden Uprising. The uprising was conceived in 1903 in Thessaloniki by the Internal Macedonian Revolutionary Organization (IMRO). The uprising in the Bitola region was planned in Smilevo village in May 1903. Battles were fought in the villages of Bistrica, Rakovo, Buf, Skocivir, Paralovo, Brod, Novaci, Smilevo, Gjavato, Capari and others. Smilevo was defended by 600 rebels led by Dame Gruev and Georgi Sugarev. They were defeated and the villages were burned. + +Balkan Wars +In 1912, Montenegro, Serbia, Bulgaria and Greece fought the Ottomans in the First Balkan War. After a victory at Sarantaporo, Greek troops advanced towards Monastir but were defeated by the Ottomans at Sorovich. The Battle of Monastir (16–19 November 1912) led to Serbian occupation of the city. According to the Treaty of Bucharest, 1913, the region of Macedonia was divided into three parts among Greece, Serbia and Bulgaria. Monastir was ceded to Serbia and its official name became the Slavic toponym Bitola. + +World War I + +During World War I Bitola was on the Salonica front. Bulgaria, a Central Power, took the city on 21 November 1915, while the Allied forces recaptured it in 1916. Bitola was divided into French, Russian, Italian and Serbian sections, under the command of French general Maurice Sarrail. Until Bulgaria's surrender in late autumn 1918, Bitola remained a front line city and was bombarded almost daily by air bombardment and artillery fire and was nearly destroyed. + +Inter-war period +At the end of World War I Bitola was restored to the Kingdom of Serbia, and, consequently, in 1918 became part of the Kingdom of Serbs, Croats and Slovenes, which was renamed Yugoslavia in 1929. Bitola became one of the major cities of the Vardarska banovina. + +World War II +During World War II (1939–45), the Germans (on 9 April 1941) and Bulgarians (on 18 April 1941) took control of the city. But in September 1944, Bulgaria switched sides in the war and withdrew from Yugoslavia. On 4 November, the 7th Macedonian Liberation Brigade entered Bitola after the German withdrawal. The historical Jewish community, of Sephardic origin, lived in the city until World War II, when some were able to immigrate to the United States and Chile. On 11 March 1943 the Bulgarians deported the vast majority of the Jewish population (3276 Jews) to Treblinka extermination camp. After the end of the war, SR Macedonia was established within SFR Yugoslavia. + +Socialist Yugoslavia +In 1945, the first Gymnasium (named "Josip Broz Tito") to use the Macedonian language, was opened in Bitola. In 1951–52, as part of a Turkification campaign total of 40 Turkish schools were opened in Debar, Kičevo, Kumanovo, Struga, Resen, Bitola, Kruševo and Prilep. + +Main sights + +The city has many historical building dating from many historical periods. The most notable ones are from the Ottoman age, but there are some from the more recent past. + +Širok Sokak + +Širok Sokak (, meaning "Wide Alley") is a long pedestrian street that runs from Magnolia Square to the City Park. + +Clock Tower + +It is unknown when Bitola's clock tower was built. Written sources from the 16th century mention a clock tower, but it is unclear if it is the same. Some believe it was built at the same time as St. Dimitrija Church in 1830. Legend says that the Ottoman authorities collected around 60,000 eggs from nearby villages and mixed them in the mortar to make the walls stronger. + +The tower has a rectangular base and is about 30 meters high. Near the top is a rectangular terrace with an iron fence. On each side of the fence is an iron console construction which holds the lamps for lighting the clock. The clock is on the highest of three levels. The original clock was replaced during World War II with a working one, given by the Nazis because the city had maintained German graves from World War I. +The massive tower is composed of walls, massive spiral stairs, wooden mezzanine constructions, pendentives and the dome. During the construction of the tower, the façade was simultaneously decorated with simple stone plastic. + +Church of Saint Demetrius +The Church of Saint Demetrius was built in 1830 with the voluntary contributions of local merchants and craftsmen. It is plain on the outside, as all churches in the Ottoman Empire had to be, but lavishly decorated with chandeliers, a carved bishop throne and an engraved iconostasis on the inside. According to some theories, iconostasis is a work of the Mijak engravers. Its most impressive feature is the arc above the imperial quarters with modelled figures of Jesus and the apostles. + +Other engraved wood items include the bishop's throne made in the spirit of Mijak engravers, several icon frames and five more-recent pillars shaped like thrones. The frescoes originate from two periods: the end of the 19th century and the end of World War I to the present. The icons and frescoes were created thanks to voluntary contributions of local businessmen and citizens. The authors of many of the icons had a vast knowledge of iconography schemes of the New Testament. The icons show a great sense of color, dominated by red, green and ochra shades. The abundance of golden ornaments is noticeable and points to the presence of late-Byzantine artwork and baroque style. The icon of Saint Demetrius is signed with the initials "D. A. Z.", showing that it was made by iconographer Dimitar Andonov the zograph in 1889. There are many other items, including the chalices made by local masters, a darohranilka of Russian origin, and several paintings of scenes from the New Testament, brought from Jerusalem by pilgrims. + +The opening scenes of the film The Peacemaker were shot in the "Saint Dimitrija" church in Bitola, as well as some Welcome to Sarajevo scenes. + +Co-Cathedral of the Sacred Heart + +Heraclea Lyncestis +Heraclea Lyncestis () was an important ancient settlement from the Hellenistic period till the early Middle Ages. It was founded by Philip II of Macedon by the middle of the 4th century BC. Today, its ruins are in the southern part of Bitola, from the city center. + +The covered bazaar + +Situated near the city centre, the covered bedisten () is one of the most impressive and oldest buildings in Bitola from the Ottoman period. With its numerous cupolas that look like a fortress, with its tree-branch-like inner streets and four large metal doors it is one of the biggest covered markets in the region. + +It was built in the 15th century by Kara Daut Pasha Uzuncarsili, then Rumelia's Beylerbey. Although the bazaar appears secure, it has been robbed and set on fire, but has managed to survive. The bedisten, from the 15th to the 19th centuries, was rebuilt, and many stores, often changing over time, were located there. Most of them were selling textile and other luxurious fabrics. At the same time the Bedisten was a treasury, where in specially made small rooms the money from the whole Rumelian Vilaet was kept, before it was transferred into the royal treasury. In the 19th century the Bedisten contained 84 shops. Today most of them are contemporary and they sell different types of products, but despite the internal renovations, the outwards appearance of the structure has remained unchanged. + +Gazi Hajdar Kadi Mosque +The Gazi Hajdar Kadi Mosque is one of the most attractive monuments of Islamic architecture in Bitola. It was built in the early 1560s, as the project of the architect Mimar Sinan, ordered by the Bitola kadija Ajdar-kadi. Over time, it was abandoned and heavily damaged, and at one point used as a stare, but recent restoration and conservation has restored to some extent its original appearance. + +New Mosque, Bitola + +The New Mosque is located in the center of the city. It has a square base, topped with a dome. Near the mosque is a minaret, 40 m high. Today, the mosque's rooms house permanent and temporary art exhibitions. Recent archaeological excavations have revealed that it has been built upon an old church. + +Ishak Çelebi Mosque +The Ishak Çelebi Mosque is the inheritance of the kadi Ishak Çelebi. In its spacious yard are several tombs, attractive because of the soft, molded shapes of the sarcophagi. + +Kodža Kadi Mosque + +The old bazaar +The old bazaar (Macedonian: Стара Чаршија) is mentioned in a description of the city from the 16th and the 17th centuries. The present bedisten does not differ much in appearance from the original one. The bedisten had eighty-six shops and four large iron gates. The shops used to sell textiles, and today sell food products. + +Deboj Bath +The Deboj Bath is a Ottoman Empire-era hamam. It is not known when exactly it was constructed. At one point, it was heavily damaged, but after repairs it regained its original appearance: a façade with two large domes and several minor ones. + +Bitola today +Bitola is the economic and industrial center of southwestern North Macedonia. Many of the largest companies in the country are based in the city. The Pelagonia agricultural combine is the largest producer of food in the country. The Streževo water system is the largest in North Macedonia and has the best technological facilities. The three thermoelectric power stations of REK Bitola produce nearly 80% of electricity in the state. The Frinko refrigerate factory was a leading electrical and metal company. Bitola also has significant capacity in the textile and food industries. + +Bitola is also home to thirteen consulates, which gives the city the nickname "the city of consuls." + +General consulates + (since 2006) + (since 2006) + +Honorary consulates + (since 2019) + (since 2014) + (since 2014) + (since 1996) + (since 2012) + (since 2008) + (since 2007) + (since 2001) + (since 2007) + (since 1998) + (since 2011) + +Former consulates + (2006-2014) + (2005-2014) + (2000-2014) + +Italy has also expressed interest in opening a consulate in Bitola. + +Media +There is only one television station in Bitola: Tera, few regional radio stations: the private Radio 105 (Bombarder), Radio 106,6, UKLO FM, Radio Delfin as well as a local weekly newspaper — Bitolski Vesnik. + +City Council +The Bitola Municipality Council () is the governing body of the city and municipality of Bitola.

It numbered some 37,500 at the end of the 19th century. There were around 7,000 Aromanians, most of whom fully embraced the Hellenic culture, although some preferred the Romanian culture. Bitola also had a significant Muslim population - 11,000 (Turks, Roma, and Albanians) as well as a Jewish community of 5,200. The Slavic-speakers were divided between the Bulgarian Exarchate - 8,000, and the Greek Patriarchate - 6,300. A significant part of the Muslim Albanian population of Bitola was Turkified during Ottoman rule. + +In statistics gathered by Vasil Kanchov in 1900, the city of Bitola was inhabited by 37,000 people, of whom 10,500 were Turks, 10,000 Christian Bulgarians, 7,000 Vlachs, 2,000 Romani, 5500 Jews, 1500 Muslim Albanians, 500 inhabitants of various other origins. The Bulgarian researcher Vasil Kanchov wrote in 1900 that many Albanians declared themselves as Turks. In Bitola, the population that declared itself Turkish "was of Albanian blood", but it "had been Turkified after the Ottoman invasion, including Skanderbeg", referring to Islamization. + +During Ottoman times, Bitola had a significant Aromanian population, which according to some sources was larger than the Bulgarian and Jewish ones. In 1901, the Italian consul to the Ottoman Empire in Bitola said that "Undoubtedly, Koutzo-Vlach [Aromanian] population in Bitola is most significant in this town in terms of number of inhabitants, social status and importance in trade". + +According to the statistics of the secretary of the Bulgarian Exarchate, Dimitar Mishev (" La Macédoine et sa Population Chrétienne "), in 1905 the Christian population of Bitola consisted of 8,844 Bulgarian Exarchists, 6,300 Greek Patriarchal Bulgarians, 72 Serboman Patriarchal Bulgarians, 36 Protestant Bulgarians, 100 Greeks . 7200 Vlachs, 120 Albanians and 120 Gypsies. In the city there are 10 primary and 3 secondary Bulgarian schools, 7 primary and 2 secondary Greek, 2 primary and 2 secondary Romanian and 1 primary and 2 secondary Serbian schools. + +According to a 1911 Ottoman census, there were 350,000 Greeks, 246,000 Bulgarians and 456,000 Muslims in the vilayet of Manastır, however the basis of the Ottoman censuses was the millet system where people were assigned an ethnicity according to their religion. Therefore, all Sunni Muslims were categorised as "Turks" even though many of them were Albanians, while all members of the Greek Orthodox church were listed as "Greeks" although this group was composed of Aromanians, Slavs, and Tosk Albanians, in addition to the Greeks which were numbered at ~100,000. The Slavic-speakers were divided between the Bulgarian majority and a small Serbian minority. + +Bulgarian ethnographer Jordan Ivanov, professor at the University of Sofia, wrote in 1915 that Albanians, since they did not have their own alphabet, lacked a consolidated national consciousness and were influenced by foreign propaganda, declared themselves as Turks, Greeks and Bulgarians, depending on which religion they belonged to. Ivan further stated that Albanians were losing their mother tongue in Bitola. German linguist Gustav Weigand describes the process of Turkification of the Albanian urban population in his 1923 work Ethnographie Makedoniens (Ethnography of Macedonia). He writes that in the cities, especially noting Bitola, many of the Turkish inhabitants are in fact Albanians, being distinguished by the difference in articulation of certain Turkish words, as well as their clothing and tool use. They speak Albanian at home, however use Turkish when in public. They refer to themselves as Turks, the term at the time also being a synonym for Muslim, with ethnic Turks referring to them as Turkoshak, a derogatory term for someone portraying themselves as Turkish. + +According to the 1948 census Bitola had 30,761 inhabitants. 77.2% (or 23,734 inhabitants) were Macedonians, 11.5% (or 3,543 inhabitants) were Turks, 4.3% (or 1,327 inhabitants) were Albanians, 3% (or 912 inhabitants) were Serbs and 1.3% (or 402 inhabitants) were Aromanians. As of 2021, the city of Bitola has 69,287 inhabitants and the ethnic composition is the following: + +In the 1953 census, large portions of Albanians declared themselves as ethnic Turks. In the municipality of Bitola, 13,166 Albanians were registered in 1948 and 4,014 in 1953, with the Turkish community going from 14,050 members in 1948, to numbering 29,151 in 1953. + +PWDTFAS-Persons for whom data are taken + +Language +According to the 2002 census the most common languages in the city are the following: + +Religion +Bitola is a bishopric city and the seat of the Diocese of Prespa- Pelagonia. In World War II the diocese was named Ohrid - Bitola. With the restoration of the autocephaly of the Macedonian Orthodox Church in 1967, it got its present name Prespa- Pelagonia diocese which covers the following regions and cities: Bitola, Resen, Prilep, Krusevo and Demir Hisar. + +The diocese's first bishop (1958 - 1979) was Mr. Kliment.

The diocese has two church museums- the cathedral "St. Martyr Demetrius" in Bitola and at the Church "St. John" in Krusevo and permanent exhibition of icons and libraries in the building of the seat of the diocese. The seat building was built between 1901 and 1902 and is an example of baroque architecture.

Fought on 22 August 1485, the battle was won by an alliance of Lancastrians and disaffected Yorkists. Their leader Henry Tudor, Earl of Richmond, became the first English monarch of the Tudor dynasty by his victory and subsequent marriage to a Yorkist princess. His opponent Richard III, the last king of the House of York, was killed during the battle, the last English monarch to die in combat. Historians consider Bosworth Field to mark the end of the Plantagenet dynasty, making it one of the defining moments of English history. + +Richard's reign began in 1483 when he ascended the throne after his twelve-year-old nephew, Edward V, was declared illegitimate. The boy and his younger brother Richard soon disappeared, and their fate is a mystery still today. Across the English Channel Henry Tudor, a descendant of the greatly diminished House of Lancaster, seized on Richard's difficulties and laid claim to the throne. Henry's first attempt to invade England in 1483 foundered in a storm, but his second arrived unopposed on 7 August 1485 on the southwest coast of Wales. Marching inland, Henry gathered support as he made for London. Richard hurriedly mustered his troops and intercepted Henry's army near Ambion Hill, south of the town of Market Bosworth in Leicestershire. Lord Stanley and Sir William Stanley also brought a force to the battlefield, but held back while they decided which side it would be most advantageous to support, initially lending only four knights to Henry's cause; these were: Sir Robert Tunstall, Sir John Savage (nephew of Lord Stanley), Sir Hugh Persall and Sir Humphrey Stanley. Sir John Savage was placed in command of the left flank of Henry's army. + +Richard divided his army, which outnumbered Henry's, into three groups (or "battles"). One was assigned to the Duke of Norfolk and another to the Earl of Northumberland. Henry kept most of his force together and placed it under the command of the experienced Earl of Oxford. Richard's vanguard, commanded by Norfolk, attacked but struggled against Oxford's men, and some of Norfolk's troops fled the field. Northumberland took no action when signalled to assist his king, so Richard gambled everything on a charge across the battlefield to kill Henry and end the fight. Seeing the king's knights separated from his army, the Stanleys intervened; Sir William led his men to Henry's aid, surrounding and killing Richard. After the battle, Henry was crowned king. + +Henry hired chroniclers to portray his reign favourably; the Battle of Bosworth Field was popularised to represent his Tudor dynasty as the start of a new age, marking the end of the Middle Ages for England. From the 15th to the 18th centuries the battle was glamourised as a victory of good over evil, and features as the climax of William Shakespeare's play Richard III. The exact site of the battle is disputed because of the lack of conclusive data, and memorials have been erected at different locations. The Bosworth Battlefield Heritage Centre was built in 1974, on a site that has since been challenged by several scholars and historians. In October 2009, a team of researchers who had performed geological surveys and archaeological digs in the area since 2003 suggested a location southwest of Ambion Hill. + +Background + +During the 15th century civil war raged across England as the Houses of York and Lancaster fought each other for the English throne. In 1471 the Yorkists defeated their rivals in the battles of Barnet and Tewkesbury. The Lancastrian King Henry VI and his only son, Edward of Westminster, died in the aftermath of the Battle of Tewkesbury. Their deaths left the House of Lancaster with no direct claimants to the throne. The Yorkist king, Edward IV, was in complete control of England. He attainted those who refused to submit to his rule, such as Jasper Tudor and his nephew Henry, naming them traitors and confiscating their lands. The Tudors tried to flee to France but strong winds forced them to land in Brittany, which was a semi-independent duchy, where they were taken into the custody of Duke Francis II. Henry's mother, Lady Margaret Beaufort, was a great-granddaughter of John of Gaunt, uncle of King Richard II and father of King Henry IV. The Beauforts were originally bastards, but Richard II legitimised them through an Act of Parliament, a decision quickly modified by a royal decree of Henry IV ordering that their descendants were not eligible to inherit the throne. Henry Tudor, the only remaining Lancastrian noble with a trace of the royal bloodline, had a weak claim to the throne, and Edward regarded him as "a nobody". The Duke of Brittany, however, viewed Henry as a valuable tool to bargain for England's aid in conflicts with France, and kept the Tudors under his protection. + +Edward IV died 12 years after Tewkesbury in April 1483. His 12-year-old elder son succeeded him as King Edward V; the younger son, nine-year-old Richard of Shrewsbury, was next in line to the throne. Edward V was too young to rule and a Royal Council was established to rule the country until the king's coming of age. Some among the council were worried when it became apparent that the relatives of Edward V's mother, Elizabeth Woodville, were plotting to use their control of the young king to dominate the council. Having offended many in their quest for wealth and power, the Woodville family was not popular. To frustrate the Woodvilles' ambitions, Lord Hastings and other members of the council turned to the new king's uncle—Richard, Duke of Gloucester, brother of Edward IV. The courtiers urged Gloucester to assume the role of Protector quickly, as had been previously requested by his now dead brother. On 29 April Gloucester, accompanied by a contingent of guards and Henry Stafford, 2nd Duke of Buckingham, took Edward V into custody and arrested several prominent members of the Woodville family. After bringing the young king to London, Gloucester had the Queen's brother Anthony Woodville, 2nd Earl Rivers, and her son by her first marriage Richard Grey executed, without trial, on charges of treason. + +On 13 June Gloucester accused Hastings of plotting with the Woodvilles and had him beheaded. Nine days the Three Estate of the Realm, an informal Parliament declared the marriage between Edward IV and Elizabeth illegal, rendering their children illegitimate and disqualifying them from the throne. With his brother's children out of the way, he was next in the line of succession and was proclaimed King Richard III on 26 June. The timing and extrajudicial nature of the deeds done to obtain the throne for Richard won him no popularity, and rumours that spoke ill of the new king spread throughout England. After they were declared bastards, the two princes were confined in the Tower of London and never seen in public again. + +In October 1483 a conspiracy emerged to displace him from the throne. The rebels were mostly loyalists to Edward IV, who saw Richard as a usurper. Their plans were coordinated by a Lancastrian, Henry's mother Lady Margaret, who was promoting her son as a candidate for the throne. The highest-ranking conspirator was Buckingham. No chronicles tell of the duke's motive in joining the plot, although historian Charles Ross proposes that Buckingham was trying to distance himself from a king who was becoming increasingly unpopular with the people. Michael Jones and Malcolm Underwood suggest that Margaret deceived Buckingham into thinking the rebels supported him to be king. + +The plan was to stage uprisings within a short time in southern and western England, overwhelming Richard's forces. Buckingham would support the rebels by invading from Wales, while Henry came in by sea. Bad timing and weather wrecked the plot. An uprising in Kent started 10 days prematurely, alerting Richard to muster the royal army and take steps to put down the insurrections. Richard's spies informed him of Buckingham's activities, and the king's men captured and destroyed the bridges across the River Severn. When Buckingham and his army reached the river, they found it swollen and impossible to cross because of a violent storm that broke on 15 October. Buckingham was trapped and had no safe place to retreat; his Welsh enemies seized his home castle after he had set forth with his army. The duke abandoned his plans and fled to Wem, where he was betrayed by his servant and arrested by Richard's men. On 2 November he was executed. Henry had attempted a landing on 10 October (or 19 October), but his fleet was scattered by a storm. He reached the coast of England (at either Plymouth or Poole) and a group of soldiers hailed him to come ashore. They were, in fact, Richard's men, prepared to capture Henry once he set foot on English soil. Henry was not deceived and returned to Brittany, abandoning the invasion. Without Buckingham or Henry, the rebellion was easily crushed by Richard. + +The survivors of the failed uprisings fled to Brittany, where they openly supported Henry's claim to the throne. At Christmas, Henry Tudor swore an oath in Rennes Cathedral to marry Edward IV's daughter, Elizabeth of York, to unite the warring houses of York and Lancaster. Henry's rising prominence made him a great threat to Richard, and the Yorkist king made several overtures to the Duke of Brittany to surrender the young Lancastrian. Francis refused, holding out for the possibility of better terms from Richard. In mid-1484 Francis was incapacitated by illness and while recuperating, his treasurer Pierre Landais took over the reins of government. Landais reached an agreement with Richard to send back Henry and his uncle in exchange for military and financial aid. John Morton, a bishop of Flanders, learned of the scheme and warned the Tudors, who fled to France. The French court allowed them to stay; the Tudors were useful pawns to ensure that Richard's England did not interfere with French plans to annex Brittany. On 16 March 1485 Richard's queen, Anne Neville, died, and rumours spread across the country that she was murdered to pave the way for Richard to marry his niece, Elizabeth. Later findings though, showed that Richard had entered into negotiations to marry Joanna of Portugal and to marry off Elizabeth to Manuel, Duke of Beja. The gossip must have upset Henry across the English Channel. The loss of Elizabeth's hand in marriage could unravel the alliance between Henry's supporters who were Lancastrians and those who were loyalists to Edward IV. Anxious to secure his bride, Henry recruited mercenaries formerly in French service to supplement his following of exiles and set sail from France on 1 August. + +Factions + +By the 15th century, English chivalric ideas of selfless service to the king had been corrupted. Armed forces were raised mostly through musters in individual estates; every able-bodied man had to respond to his lord's call to arms, and each noble had authority over his militia. Although a king could raise personal militia from his lands, he could muster a large army only through the support of his nobles. Richard, like his predecessors, had to win over these men by granting gifts and maintaining cordial relationships. Powerful nobles could demand greater incentives to remain on the liege's side or else they might turn against him. Three groups, each with its own agenda, stood on Bosworth Field: Richard III and his Yorkist army; his challenger, Henry Tudor, who championed the Lancastrian cause; and the fence-sitting Stanleys. + +Yorkist +Small and slender, Richard III did not have the robust physique associated with many of his Plantagenet predecessors. However, he enjoyed very rough sports and activities that were considered manly. His performances on the battlefield impressed his brother greatly, and he became Edward's right-hand man. During the 1480s Richard defended the northern borders of England. In 1482, Edward charged him to lead an army into Scotland with the aim of replacing King James III with the Duke of Albany. Richard's army broke through the Scottish defences and occupied the capital, Edinburgh, but Albany decided to give up his claim to the throne in return for the post of Lieutenant General of Scotland. As well as obtaining a guarantee that the Scottish government would concede territories and diplomatic benefits to the English crown, Richard's campaign retook the town of Berwick-upon-Tweed, which the Scots had conquered in 1460. Edward was not satisfied by these gains, which, according to Ross, could have been greater if Richard had been resolute enough to capitalise on the situation while in control of Edinburgh. In her analysis of Richard's character, Christine Carpenter sees him as a soldier who was more used to taking orders than giving them. However, he was not averse to displaying his militaristic streak; on ascending the throne he made known his desire to lead a crusade against "not only the Turks, but all [his] foes". + +Richard's most loyal subject was John Howard, 1st Duke of Norfolk. The duke had served Richard's brother for many years and had been one of Edward IV's closer confidants. He was a military veteran, having fought in the Battle of Towton in 1461 and served as Hastings' deputy at Calais in 1471. Ross speculates that he bore a grudge against Edward for depriving him of a fortune. Norfolk was due to inherit a share of the wealthy Mowbray estate on the death of eight-year-old Anne de Mowbray, the last of her family. However, Edward convinced Parliament to circumvent the law of inheritance and transfer the estate to his younger son, who was married to Anne. Consequently, Howard supported Richard III in deposing Edward's sons, for which he received the dukedom of Norfolk and his original share of the Mowbray estate. + +Henry Percy, 4th Earl of Northumberland, also supported Richard's ascension to the throne of England. The Percys were loyal Lancastrians, but Edward IV eventually won the earl's allegiance. Northumberland had been captured and imprisoned by the Yorkists in 1461, losing his titles and estates; however, Edward released him eight years later and restored his earldom. From that time Northumberland served the Yorkist crown, helping to defend northern England and maintain its peace. Initially the earl had issues with Richard III as Edward groomed his brother to be the leading power of the north. Northumberland was mollified when he was promised he would be the Warden of the East March, a position that was formerly hereditary for the Percys. He served under Richard during the 1482 invasion of Scotland, and the allure of being in a position to dominate the north of England if Richard went south to assume the crown was his likely motivation for supporting Richard's bid for kingship. However, after becoming king, Richard began moulding his nephew, John de la Pole, 1st Earl of Lincoln, to manage the north, passing over Northumberland for the position. According to Carpenter, although the earl was amply compensated, he despaired of any possibility of advancement under Richard. + +Lancastrians +Henry Tudor was unfamiliar with the arts of war and was a stranger to the land he was trying to conquer. He spent the first fourteen years of his life in Wales and the next fourteen in Brittany and France. Slender but strong and decisive, Henry lacked a penchant for battle and was not much of a warrior; chroniclers such as Polydore Vergil and ambassadors like Pedro de Ayala found him more interested in commerce and finance. Having not fought in any battles, Henry recruited several experienced veterans to command his armies. + +John de Vere, 13th Earl of Oxford, was Henry's principal military commander. He was adept in the arts of war. At the Battle of Barnet, he commanded the Lancastrian right wing and routed the division opposing him. However, as a result of confusion over identities, Oxford's group came under friendly fire from the Lancastrian main force and retreated from the field. The earl fled abroad and continued his fight against the Yorkists, raiding shipping and eventually capturing the island fort of St Michael's Mount in 1473. He surrendered after receiving no aid or reinforcement, but in 1484 escaped from prison and joined Henry's court in France, bringing along his erstwhile gaoler Sir James Blount. Oxford's presence raised morale in Henry's camp and troubled Richard III. + +Stanleys +In the early stages of the Wars of the Roses, the Stanleys of Cheshire had been predominantly Lancastrians. Sir William Stanley, however, was a staunch Yorkist supporter, fighting in the Battle of Blore Heath in 1459 and helping Hastings to put down uprisings against Edward IV in 1471. When Richard took the crown, Sir William showed no inclination to turn against the new king, refraining from joining Buckingham's rebellion, for which he was amply rewarded. Sir William's elder brother, Thomas Stanley, 2nd Baron Stanley, was not as steadfast. By 1485, he had served three kings, namely Henry VI, Edward IV, and Richard III. Lord Stanley's skilled political manoeuvrings—vacillating between opposing sides until it was clear who would be the winner—gained him high positions; he was Henry's chamberlain and Edward's steward. His non-committal stance, until the crucial point of a battle, earned him the loyalty of his men, who felt he would not needlessly send them to their deaths. + +Lord Stanley's relations with the king's brother, the eventual Richard III, were not cordial. The two had conflicts that erupted into violence around March 1470. Furthermore, having taken Lady Margaret as his second wife in June 1472, Stanley was Henry Tudor's stepfather, a relationship which did nothing to win him Richard's favour. Despite these differences, Stanley did not join Buckingham's revolt in 1483. When Richard executed those conspirators who had been unable to flee England, he spared Lady Margaret. However, he declared her titles forfeit and transferred her estates to Stanley's name, to be held in trust for the Yorkist crown. Richard's act of mercy was calculated to reconcile him with Stanley, but it may have been to no avail—Carpenter has identified a further cause of friction in Richard's intention to reopen an old land dispute that involved Thomas Stanley and the Harrington family. Edward IV had ruled the case in favour of Stanley in 1473, but Richard planned to overturn his brother's ruling and give the wealthy estate to the Harringtons. Immediately before the Battle of Bosworth, being wary of Stanley, Richard took his son, Lord Strange, as hostage to discourage him from joining Henry. + +Crossing the English Channel and through Wales +Henry's initial force consisted of the English and Welsh exiles who had gathered around Henry, combined with a contingent of mercenaries put at his disposal by Charles VIII of France. The history of Scottish author John Major (published in 1521) claims that Charles had granted Henry 5,000 men, of whom 1,000 were Scots, headed by Sir Alexander Bruce. No mention of Scottish soldiers was made by subsequent English historians. + +Henry's crossing of the English Channel in 1485 was without incident. Thirty ships sailed from Harfleur on 1 August and, with fair winds behind them, landed in his native Wales, at Mill Bay (near Dale) on the north side of Milford Haven on 7 August, easily capturing nearby Dale Castle. Henry received a muted response from the local population. No joyous welcome awaited him on shore, and at first few individual Welshmen joined his army as it marched inland. Historian Geoffrey Elton suggests only Henry's ardent supporters felt pride over his Welsh blood. His arrival had been hailed by contemporary Welsh bards such as Dafydd Ddu and Gruffydd ap Dafydd as the true prince and "the youth of Brittany defeating the Saxons" in order to bring their country back to glory. When Henry moved to Haverfordwest, the county town of Pembrokeshire, Richard's lieutenant in South Wales, Sir Walter Herbert, failed to move against Henry, and two of his officers, Richard Griffith and Evan Morgan, deserted to Henry with their men. + +The most important defector to Henry in this early stage of the campaign was probably Rhys ap Thomas, who was the leading figure in West Wales. Richard had appointed Rhys Lieutenant in West Wales for his refusal to join Buckingham's rebellion, asking that he surrender his son Gruffydd ap Rhys ap Thomas as surety, although by some accounts Rhys had managed to evade this condition. However, Henry successfully courted Rhys, offering the lieutenancy of all Wales in exchange for his fealty. Henry marched via Aberystwyth while Rhys followed a more southerly route, recruiting a force of Welshmen en route, variously estimated at 500 or 2,000 men, to swell Henry's army when they reunited at Cefn Digoll, Welshpool. By 15 or 16 August, Henry and his men had crossed the English border, making for the town of Shrewsbury. + +Shrewsbury: the gateway to England + +Since 22 June Richard had been aware of Henry's impending invasion, and had ordered his lords to maintain a high level of readiness. News of Henry's landing reached Richard on 11 August, but it took three to four days for his messengers to notify his lords of their king's mobilisation. On 16 August, the Yorkist army started to gather; Norfolk set off for Leicester, the assembly point, that night. The city of York, a historical stronghold of Richard's family, asked the king for instructions, and receiving a reply three days later sent 80 men to join the king. Simultaneously Northumberland, whose northern territory was the most distant from the capital, had gathered his men and ridden to Leicester. + +Although London was his goal, Henry did not move directly towards the city. After resting in Shrewsbury, his forces went eastwards and picked up Sir Gilbert Talbot and other English allies, including deserters from Richard's forces. Although its size had increased substantially since the landing, Henry's army was still considerably outnumbered by Richard's forces. Henry's pace through Staffordshire was slow, delaying the confrontation with Richard so that he could gather more recruits to his cause. Henry had been communicating on friendly terms with the Stanleys for some time before setting foot in England, and the Stanleys had mobilised their forces on hearing of Henry's landing. They ranged themselves ahead of Henry's march through the English countryside, meeting twice in secret with Henry as he moved through Staffordshire. At the second of these, at Atherstone in Warwickshire, they conferred "in what sort to arraign battle with King Richard, whom they heard to be not far off". On 21 August, the Stanleys were making camp on the slopes of a hill north of Dadlington, while Henry encamped his army at White Moors to the northwest of their camp. + +On 20 August, Richard rode from Nottingham to Leicester, joining Norfolk. He spent the night at the Blue Boar inn (demolished 1836). Northumberland arrived the following day. The royal army proceeded westwards to intercept Henry's march on London. Passing Sutton Cheney, Richard moved his army towards Ambion Hill—which he thought would be of tactical value—and made camp on it. Richard's sleep was not peaceful and, according to the Croyland Chronicle, in the morning his face was "more livid and ghastly than usual". + +Engagement + +The Yorkist army, variously estimated at between 7,500 and 12,000 men, deployed on the hilltop along the ridgeline from west to east. Norfolk's force (or "battle" in the parlance of the time) of spearmen stood on the right flank, protecting the cannon and about 1,200 archers. Richard's group, comprising 3,000 infantry, formed the centre. Northumberland's men guarded the left flank; he had approximately 4,000 men, many of them mounted. Standing on the hilltop, Richard had a wide, unobstructed view of the area. He could see the Stanleys and their 4,000–6,000 men holding positions on and around Dadlington Hill, while to the southwest was Henry's army. + +Henry's force has been variously estimated at between 5,000 and 8,000 men, his original landing force of exiles and mercenaries having been augmented by the recruits gathered in Wales and the English border counties (in the latter area probably mustered chiefly by the Talbot interest), and by deserters from Richard's army. Historian John Mackie believes that 1,800 French mercenaries, led by Philibert de Chandée, formed the core of Henry's army. John Mair, writing thirty-five years after the battle, claimed that this force contained a significant Scottish component, and this claim is accepted by some modern writers, but Mackie reasons that the French would not have released their elite Scottish knights and archers, and concludes that there were probably few Scottish troops in the army, although he accepts the presence of captains like Bernard Stewart, Lord of Aubigny. + +In their interpretations of the vague mentions of the battle in the old text, historians placed areas near the foot of Ambion Hill as likely regions where the two armies clashed, and thought up possible scenarios of the engagement. In their recreations of the battle, Henry started by moving his army towards Ambion Hill where Richard and his men stood. As Henry's army advanced past the marsh at the southwestern foot of the hill, Richard sent a message to Stanley, threatening to execute his son, Lord Strange, if Stanley did not join the attack on Henry immediately. Stanley replied that he had other sons. Incensed, Richard gave the order to behead Strange but his officers temporised, saying that battle was imminent, and it would be more convenient to carry out the execution afterwards. Henry had also sent messengers to Stanley asking him to declare his allegiance. The reply was evasive—the Stanleys would "naturally" come, after Henry had given orders to his army and arranged them for battle. Henry had no choice but to confront Richard's forces alone. + +Well aware of his own military inexperience, Henry handed command of his army to Oxford and retired to the rear with his bodyguards. Oxford, seeing the vast line of Richard's army strung along the ridgeline, decided to keep his men together instead of splitting them into the traditional three battles: vanguard, centre, and rearguard. He ordered the troops to stray no further than from their banners, fearing that they would become enveloped. Individual groups clumped together, forming a single large mass flanked by horsemen on the wings. + +The Lancastrians were harassed by Richard's cannon as they manoeuvred around the marsh, seeking firmer ground. Once Oxford and his men were clear of the marsh, Norfolk's battle and several contingents of Richard's group, under the command of Sir Robert Brackenbury, started to advance. Hails of arrows showered both sides as they closed. Oxford's men proved the steadier in the ensuing hand-to-hand combat; they held their ground and several of Norfolk's men fled the field. Norfolk lost one of his senior officers, Walter Devereux, in this early clash. + +Recognising that his force was at a disadvantage, Richard signalled for Northumberland to assist but Northumberland's group showed no signs of movement. Historians, such as Horrox and Pugh, believe Northumberland chose not to aid his king for personal reasons. Ross doubts the aspersions cast on Northumberland's loyalty, suggesting instead that Ambion Hill's narrow ridge hindered him from joining the battle. The earl would have had to either go through his allies or execute a wide flanking move—near impossible to perform given the standard of drill at the time—to engage Oxford's men. + +At this juncture Richard saw Henry at some distance behind his main force. Seeing this, Richard decided to end the fight quickly by killing the enemy commander. He led a charge of mounted men around the melee and tore into Henry's group; several accounts state that Richard's force numbered 800–1000 knights, but Ross says it was more likely that Richard was accompanied only by his household men and closest friends. Richard killed Henry's standard-bearer Sir William Brandon in the initial charge and unhorsed burly John Cheyne, Edward IV's former standard-bearer, with a blow to the head from his broken lance. French mercenaries in Henry's retinue related how the attack had caught them off guard and that Henry sought protection by dismounting and concealing himself among them to present less of a target. Henry made no attempt to engage in combat himself. + +Oxford had left a small reserve of pike-equipped men with Henry. They slowed the pace of Richard's mounted charge, and bought Tudor some critical time. The remainder of Henry's bodyguards surrounded their master, and succeeded in keeping him away from the Yorkist king. Meanwhile, seeing Richard embroiled with Henry's men and separated from his main force, William Stanley made his move and rode to the aid of Henry. Now outnumbered, Richard's group was surrounded and gradually pressed back. Richard's force was driven several hundred yards away from Tudor, near to the edge of a marsh, into which the king's horse toppled. Richard, now unhorsed, gathered himself and rallied his dwindling followers, supposedly refusing to retreat: "God forbid that I retreat one step. I will either win the battle as a king, or die as one." In the fighting Richard's banner man—Sir Percival Thirlwall—lost his legs, but held the Yorkist banner aloft until he was killed. It is likely that James Harrington also died in the charge. The king's trusted advisor Richard Ratcliffe was also slain. + +Polydore Vergil, Henry Tudor's official historian, recorded that "King Richard, alone, was killed fighting manfully in the thickest press of his enemies". Richard had come within a sword's length of Henry Tudor before being surrounded by William Stanley's men and killed. The Burgundian chronicler Jean Molinet says that a Welshman struck the death-blow with a halberd while Richard's horse was stuck in the marshy ground. It was said that the blows were so violent that the king's helmet was driven into his skull. The contemporary Welsh poet Guto'r Glyn implies the leading Welsh Lancastrian Rhys ap Thomas, or one of his men, killed the king, writing that he ("Killed the boar, shaved his head"). Analysis of King Richard's skeletal remains found 11 wounds, nine of them to the head; a blade consistent with a halberd had sliced off part of the rear of Richard's skull, suggesting he had lost his helmet. + +Richard's forces disintegrated as news of his death spread. Northumberland and his men fled north on seeing the king's fate, and Norfolk was killed by the knight Sir John Savage in single combat according to the Ballad of Lady Bessy. + +After the battle + +Although he claimed fourth-generation, maternal Lancastrian descendancy, Henry seized the crown by right of conquest. After the battle, Richard's circlet is said to have been found and brought to Henry, who was proclaimed king at the top of Crown Hill, near the village of Stoke Golding. According to Vergil, Henry's official historian, Lord Stanley found the circlet. Historians Stanley Chrimes and Sydney Anglo dismiss the legend of the circlet's finding in a hawthorn bush; none of the contemporary sources reported such an event. Ross, however, does not ignore the legend. He argues that the hawthorn bush would not be part of Henry's coat of arms if it did not have a strong relationship to his ascendance. Baldwin points out that a hawthorn bush motif was already used by the House of Lancaster, and Henry merely added the crown. + +In Vergil's chronicle, 100 of Henry's men, compared to 1,000 of Richard's, died in this battle—a ratio Chrimes believes to be an exaggeration. The bodies of the fallen were brought to St James Church at Dadlington for burial. However, Henry denied any immediate rest for Richard; instead the last Yorkist king's corpse was stripped naked and strapped across a horse. His body was brought to Leicester and openly exhibited to prove that he was dead. Early accounts suggest that this was in the major Lancastrian collegiate foundation, the Church of the Annunciation of Our Lady of the Newarke. After two days, the corpse was interred in a plain tomb, within the church of the Greyfriars. The church was demolished following the friary's dissolution in 1538, and the location of Richard's tomb was long uncertain. + +On 12 September 2012, archaeologists announced the discovery of a buried skeleton with spinal abnormalities and head injuries under a car park in Leicester, and their suspicions that it was Richard III. On 4 February 2013, it was announced that DNA testing had convinced Leicester University scientists and researchers "beyond reasonable doubt" that the remains were those of King Richard. On 26 March 2015, these remains were ceremonially buried in Leicester Cathedral. Richard's tomb was unveiled on the following day. + +Henry dismissed the mercenaries in his force, retaining only a small core of local soldiers to form a "Yeomen of his Garde", and proceeded to establish his rule of England. Parliament reversed his attainder and recorded Richard's kingship as illegal, although the Yorkist king's reign remained officially in the annals of England history. The proclamation of Edward IV's children as illegitimate was also reversed, restoring Elizabeth's status to a royal princess. The marriage of Elizabeth, the heiress to the House of York, to Henry, the master of the House of Lancaster, marked the end of the feud between the two houses and the start of the Tudor dynasty. The royal matrimony, however, was delayed until Henry was crowned king and had established his claim on the throne firmly enough to preclude that of Elizabeth and her kin. Henry further convinced Parliament to backdate his reign to the day before the battle, enabling him retrospectively to declare as traitors those who had fought against him at Bosworth Field. Northumberland, who had remained inactive during the battle, was imprisoned but later released and reinstated to pacify the north in Henry's name. The purge of those who fought for Richard occupied Henry's first two years of rule, although later he proved prepared to accept those who submitted to him regardless of their former allegiances. + +Of his supporters, Henry rewarded the Stanleys the most generously. Aside from making William his chamberlain, he bestowed the earldom of Derby upon Lord Stanley along with grants and offices in other estates. Henry rewarded Oxford by restoring to him the lands and titles confiscated by the Yorkists and appointing him as Constable of the Tower and admiral of England, Ireland, and Aquitaine. For his kin, Henry created Jasper Tudor the Duke of Bedford. He returned to his mother the lands and grants stripped from her by Richard, and proved to be a filial son, granting her a place of honour in the palace and faithfully attending to her throughout his reign. Parliament's declaration of Margaret as femme sole effectively empowered her; she no longer needed to manage her estates through Stanley. Elton points out that despite his initial largesse, Henry's supporters at Bosworth would enjoy his special favour for only the short term; in later years, he would instead promote those who best served his interests. + +Like the kings before him, Henry faced dissenters. The first open revolt occurred two years after Bosworth Field; Lambert Simnel claimed to be Edward Plantagenet, 17th Earl of Warwick, who was Edward IV's nephew. The Earl of Lincoln backed him for the throne and led rebel forces in the name of the House of York. The rebel army fended off several attacks by Northumberland's forces, before engaging Henry's army at the Battle of Stoke Field on 16 June 1487. Oxford and Bedford led Henry's men, including several former supporters of Richard III. Henry won this battle easily, but other malcontents and conspiracies would follow. A rebellion in 1489 started with Northumberland's murder; military historian Michael C. C. Adams says that the author of a note, which was left next to Northumberland's body, blamed the earl for Richard's death. + +Legacy and historical significance +Contemporary accounts of the Battle of Bosworth can be found in four main sources, one of which is the English Croyland Chronicle, written by a senior Yorkist chronicler who relied on second-hand information from nobles and soldiers. The other accounts were written by foreigners—Vergil, Jean Molinet, and Diego de Valera. Whereas Molinet was sympathetic to Richard, Vergil was in Henry's service and drew information from the king and his subjects to portray them in a good light. Diego de Valera, whose information Ross regards as unreliable, compiled his work from letters of Spanish merchants. However, other historians have used Valera's work to deduce possibly valuable insights not readily evident in other sources. Ross finds the poem, The Ballad of Bosworth Field, a useful source to ascertain certain details of the battle. The multitude of different accounts, mostly based on second- or third-hand information, has proved an obstacle to historians as they try to reconstruct the battle. Their common complaint is that, except for its outcome, very few details of the battle are found in the chronicles. According to historian Michael Hicks, the Battle of Bosworth is one of the worst-recorded clashes of the Wars of the Roses. + +Historical depictions and interpretations + +Henry tried to present his victory as a new beginning for the country; he hired chroniclers to portray his reign as a "modern age" with its dawn in 1485. Hicks states that the works of Vergil and the blind historian Bernard André, promoted by subsequent Tudor administrations, became the authoritative sources for writers for the next four hundred years. As such, Tudor literature paints a flattering picture of Henry's reign, depicting the Battle of Bosworth as the final clash of the civil war and downplaying the subsequent uprisings. For England the Middle Ages ended in 1485, and English Heritage claims that other than William the Conqueror's successful invasion of 1066, no other year holds more significance in English history. By portraying Richard as a hunchbacked tyrant who usurped the throne by killing his nephews, the Tudor historians attached a sense of myth to the battle: it became an epic clash between good and evil with a satisfying moral outcome. According to Reader Colin Burrow, André was so overwhelmed by the historic significance of the battle that he represented it with a blank page in his Henry VII (1502). For Professor Peter Saccio, the battle was indeed a unique clash in the annals of English history, because "the victory was determined, not by those who fought, but by those who delayed fighting until they were sure of being on the winning side." + +Historians such as Adams and Horrox believe that Richard lost the battle not for any mythic reasons, but because of morale and loyalty problems in his army. Most of the common soldiers found it difficult to fight for a liege whom they distrusted, and some lords believed that their situation might improve if Richard were dethroned. According to Adams, against such duplicities Richard's desperate charge was the only knightly behaviour on the field. As fellow historian Michael Bennet puts it, the attack was "the swan-song of [mediaeval] English chivalry". Adams believes this view was shared at the time by the printer William Caxton, who enjoyed sponsorship from Edward IV and Richard III. Nine days after the battle, Caxton published Thomas Malory's story about chivalry and death by betrayal—Le Morte d'Arthur—seemingly as a response to the circumstances of Richard's death. + +Elton does not believe Bosworth Field has any true significance, pointing out that the 20th-century English public largely ignored the battle until its quincentennial celebration. In his view, the dearth of specific information about the battle—no-one even knows exactly where it took place—demonstrates its insignificance to English society. Elton considers the battle as just one part of Henry's struggles to establish his reign, underscoring his point by noting that the young king had to spend ten more years pacifying factions and rebellions to secure his throne. + +Mackie asserts that, in hindsight, Bosworth Field is notable as the decisive battle that established a dynasty which would rule unchallenged over England for more than a hundred years. Mackie notes that contemporary historians of that time, wary of the three royal successions during the long Wars of the Roses, considered Bosworth Field just another in a lengthy series of such battles. It was through the works and efforts of Francis Bacon and his successors that the public started to believe the battle had decided their futures by bringing about "the fall of a tyrant". + +Shakespearean dramatisation +William Shakespeare gives prominence to the Battle of Bosworth in his play, Richard III. It is the "one big battle"; no other fighting scene distracts the audience from this action, represented by a one-on-one sword fight between Henry Tudor and Richard III. Shakespeare uses their duel to bring a climactic end to the play and the Wars of the Roses; he also uses it to champion morality, portraying the "unequivocal triumph of good over evil". Richard, the villainous lead character, has been built up in the battles of Shakespeare's earlier play, Henry VI, Part 3, as a "formidable swordsman and a courageous military leader"—in contrast to the dastardly means by which he becomes king in Richard III. Although the Battle of Bosworth has only five sentences to direct it, three scenes and more than four hundred lines precede the action, developing the background and motivations for the characters in anticipation of the battle. + +Shakespeare's account of the battle was mostly based on chroniclers Edward Hall's and Raphael Holinshed's dramatic versions of history, which were sourced from Vergil's chronicle. However, Shakespeare's attitude towards Richard was shaped by scholar Thomas More, whose writings displayed extreme bias against the Yorkist king. The result of these influences is a script that vilifies the king, and Shakespeare had few qualms about departing from history to incite drama. Margaret of Anjou died in 1482, but Shakespeare had her speak to Richard's mother before the battle to foreshadow Richard's fate and fulfill the prophecy she had given in Henry VI. Shakespeare exaggerated the cause of Richard's restless night before the battle, imagining it as a haunting by the ghosts of those whom the king had murdered, including Buckingham. Richard is portrayed as suffering a pang of conscience, but as he speaks he regains his confidence and asserts that he will be evil, if such needed to retain his crown. + +The fight between the two armies is simulated by rowdy noises made off-stage (alarums or alarms) while actors walk on-stage, deliver their lines, and exit. To build anticipation for the duel, Shakespeare requests more alarums after Richard's councillor, William Catesby, announces that the king is "[enacting] more wonders than a man". Richard punctuates his entrance with the classic line, "A horse, a horse! My kingdom for a horse!" He refuses to withdraw, continuing to seek to slay Henry's doubles until he has killed his nemesis. There is no documentary evidence that Henry had five decoys at Bosworth Field; the idea was Shakespeare's invention. He drew inspiration from Henry IV's use of them at the Battle of Shrewsbury (1403) to amplify the perception of Richard's courage on the battlefield. Similarly, the single combat between Henry and Richard is Shakespeare's creation. The True Tragedy of Richard III, by an unknown playwright, earlier than Shakespeare's, has no signs of staging such an encounter: its stage directions give no hint of visible combat. + +Despite the dramatic licences taken, Shakespeare's version of the Battle of Bosworth was the model of the event for English textbooks for many years during the 18th and 19th centuries. This glamorised version of history, promulgated in books and paintings and played out on stages across the country, perturbed humorist Gilbert Abbott à Beckett. He voiced his criticism in the form of a poem, equating the romantic view of the battle to watching a "fifth-rate production of Richard III": shabbily costumed actors fight the Battle of Bosworth on-stage while those with lesser roles lounge at the back, showing no interest in the proceedings. + +In Laurence Olivier's 1955 film adaptation of Richard III, the Battle of Bosworth is represented not by a single duel but a general melee that became the film's most recognised scene and a regular screening at Bosworth Battlefield Heritage Centre. The film depicts the clash between the Yorkist and Lancastrian armies on an open field, focusing on individual characters amidst the savagery of hand-to-hand fighting, and received accolades for the realism portrayed. One reviewer for The Manchester Guardian newspaper, however, was not impressed, finding the number of combatants too sparse for the wide plains and a lack of subtlety in Richard's death scene. The means by which Richard is shown to prepare his army for the battle also earned acclaim. As Richard speaks to his men and draws his plans in the sand using his sword, his units appear on-screen, arraying themselves according to the lines that Richard had drawn. Intimately woven together, the combination of pictorial and narrative elements effectively turns Richard into a storyteller, who acts out the plot he has constructed. Shakespearian critic Herbert Coursen extends that imagery: Richard sets himself up as a creator of men, but dies amongst the savagery of his creations. Coursen finds the depiction a contrast to that of Henry V and his "band of brothers". + +The adaptation of the setting for Richard III to a 1930s fascist England in Ian McKellen's 1995 film, however, did not sit well with historians. Adams posits that the original Shakespearian setting for Richard's fate at Bosworth teaches the moral of facing one's fate, no matter how unjust it is, "nobly and with dignity". By overshadowing the dramatic teaching with special effects, McKellen's film reduces its version of the battle to a pyrotechnic spectacle about the death of a one-dimensional villain. Coursen agrees that, in this version, the battle and Richard's end are trite and underwhelming. + +Battlefield location + +The site of the battle is deemed by Leicestershire County Council to be in the vicinity of the town of Market Bosworth. The council engaged historian Daniel Williams to research the battle, and in 1974 his findings were used to build the Bosworth Battlefield Heritage Centre and the presentation it houses. Williams's interpretation, however, has since been questioned. Sparked by the battle's quincentenary celebration in 1985, a dispute among historians has led many to doubt the accuracy of Williams's theory. In particular, geological surveys conducted from 2003 to 2009 by the Battlefields Trust, a charitable organisation that protects and studies old English battlefields, show that the southern and eastern flanks of Ambion Hill were solid ground in the 15th century, contrary to Williams's claim that it was a large area of marshland. Landscape archaeologist Glenn Foard, leader of the survey, said the collected soil samples and finds of medieval military equipment suggest that the battle took place southwest of Ambion Hill (52°34′41″N 1°26′02″W), contrary to the popular belief that it was fought near the foot of the hill. + +Historians' theories + +English Heritage argues that the battle was named after Market Bosworth because the town was then the nearest significant settlement to the battlefield. As explored by Professor Philip Morgan, a battle might initially not be named specifically at all. As time passes, writers of administrative and historical records find it necessary to identify a notable battle, ascribing it a name that is usually toponymical in nature and sourced from combatants or observers. This name then becomes accepted by society and without question. Early records associated the Battle of Bosworth with "Brownehethe", "bellum Miravallenses", "Sandeford" and "Dadlyngton field". The earliest record, a municipal memorandum of 23 August 1485 from York, locates the battle "on the field of Redemore". This is corroborated by a 1485–86 letter that mentions "Redesmore" as its site. According to the historian, Peter Foss, records did not associate the battle with "Bosworth" until 1510. + +Foss is named by English Heritage as the principal advocate for "Redemore" as the battle site. He suggests the name is derived from "Hreod Mor", an Anglo-Saxon phrase that means "reedy marshland". Basing his opinion on 13th- and 16th-century church records, he believes "Redemore" was an area of wetland that lay between Ambion Hill and the village of Dadlington, and was close to the Fenn Lanes, a Roman road running east to west across the region. Foard believes this road to be the most probable route that both armies took to reach the battlefield. Williams dismisses the notion of "Redmore" as a specific location, saying that the term refers to a large area of reddish soil; Foss argues that Williams's sources are local stories and flawed interpretations of records. Moreover, he proposes that Williams was influenced by William Hutton's 1788 The Battle of Bosworth-Field, which Foss blames for introducing the notion that the battle was fought west of Ambion Hill on the north side of the River Sence. Hutton, as Foss suggests, misinterpreted a passage from his source, Raphael Holinshed's 1577 Chronicle. Holinshed wrote, "King Richard pitched his field on a hill called Anne Beame, refreshed his soldiers and took his rest." Foss believes that Hutton mistook "field" to mean "field of battle", thus creating the idea that the fight took place on Anne Beame (Ambion) Hill. To "[pitch] his field", as Foss clarifies, was a period expression for setting up a camp. + +Foss brings further evidence for his "Redemore" theory by quoting Edward Hall's 1550 Chronicle. Hall stated that Richard's army stepped onto a plain after breaking camp the next day. Furthermore, historian William Burton, author of Description of Leicestershire (1622), wrote that the battle was "fought in a large, flat, plaine, and spacious ground, three miles [5 km] distant from [Bosworth], between the Towne of Shenton, Sutton [Cheney], Dadlington and Stoke [Golding]". In Foss's opinion both sources are describing an area of flat ground north of Dadlington. + +Physical site +English Heritage, responsible for managing England's historic sites, used both theories to designate the site for Bosworth Field. Without preference for either theory, they constructed a single continuous battlefield boundary that encompasses the locations proposed by both Williams and Foss. The region has experienced extensive changes over the years, starting after the battle. Holinshed stated in his chronicle that he found firm ground where he expected the marsh to be, and Burton confirmed that by the end of the 16th century, areas of the battlefield were enclosed and had been improved to make them agriculturally productive. Trees were planted on the south side of Ambion Hill, forming Ambion Wood. In the 18th and 19th centuries, the Ashby Canal carved through the land west and south-west of Ambion Hill. Winding alongside the canal at a distance, the Ashby and Nuneaton Joint Railway crossed the area on an embankment. The changes to the landscape were so extensive that when Hutton revisited the region in 1807 after an earlier 1788 visit, he could not readily find his way around. + +Bosworth Battlefield Heritage Centre was built on Ambion Hill, near Richard's Well. According to legend, Richard III drank from one of the several springs in the region on the day of the battle. In 1788, a local pointed out one of the springs to Hutton as the one mentioned in the legend. A stone structure was later built over the location. The inscription on the well reads: + +Northwest of Ambion Hill, just across the northern tributary of the , a flag and memorial stone mark Richard's Field. Erected in 1973, the site was selected on the basis of Williams's theory. St James's Church at Dadlington is the only structure in the area that is reliably associated with the Battle of Bosworth; the bodies of those killed in the battle were buried there. + +Rediscovered battlefield and possible battle scenario +The very extensive survey carried out (2005–2009) by the Battlefields Trust headed by Glenn Foard led eventually to the discovery of the real location of the core battlefield. This lies about a kilometre further west of the location suggested by Peter Foss. It is in what was at the time of the battle an area of marginal land at the meeting of several township boundaries. There was a cluster of field names suggesting the presence of marshland and heath. Thirty four lead round shot were discovered as a result of systematic metal detecting (more than the total found previously on all other C15th European battlefields), as well as other significant finds, including a small silver gilt badge depicting a boar. Experts believe that the boar badge could indicate the actual site of Richard III's death, since this high-status badge depicting his personal emblem was probably worn by a member of his close retinue. + +A new interpretation of the battle now integrates the historic accounts with the battlefield finds and landscape history. The new site lies either side of the Fenn Lanes Roman road, close to Fenn Lane Farm and is some three kilometres to the southwest of Ambion Hill. +Based on the round shot scatter, the likely size of Richard III's army, and the topography, Glenn Foard and Anne Curry think that Richard may have lined up his forces on a slight ridge which lies just east of Fox Covert Lane and behind a postulated medieval marsh. Richard's vanguard commanded by the Duke of Norfolk was on the right (north) side of Richard's battle line, with the Earl of Northumberland on Richard's left (south) side. + +Tudor's forces approached along the line of the Roman road and lined up to the west of the present day Fenn Lane Farm, having marched from the vicinity of Merevale in Warwickshire. +Historic England have re-defined the boundaries of the registered Bosworth Battlefield to incorporate the newly identified site. There are hopes that public access to the site will be possible in the future. + +References + +Citations + +General sources + +Books + + + + + + + + + + + + + + + + + + + + + + + + Jones, Michael.

Most are herbaceous plants, while some are shrubs. The leaves are simple (although are sometimes deeply incised), lack stipules, and appear alternately on stems or in rosettes. The inflorescences are terminal and lack bracts. The flowers have four free sepals, four free alternating petals, two shorter free stamens and four longer free stamens. The fruit has seeds in rows, divided by a thin wall (or septum). + +The family contains 372 genera and 4,060 accepted species. The largest genera are Draba (440 species), Erysimum (261 species), Lepidium (234 species), Cardamine (233 species), and Alyssum (207 species). + +The family contains the cruciferous vegetables, including species such as Brassica oleracea (cultivated as cabbage, kale, cauliflower, broccoli and collards), Brassica rapa (turnip, Chinese cabbage, etc.), Brassica napus (rapeseed, etc.), Raphanus sativus (common radish), Armoracia rusticana (horseradish), but also a cut-flower Matthiola (stock) and the model organism Arabidopsis thaliana (thale cress). + +Pieris rapae and other butterflies of the family Pieridae are some of the best-known pests of Brassicaceae species planted as commercial crops. Trichoplusia ni (cabbage looper) moth is also becoming increasingly problematic for crucifers due to its resistance to commonly used pest control methods. Some rarer Pieris butterflies, such as P. virginiensis, depend upon native mustards for their survival in their native habitats. Some non-native mustards such as Alliaria petiolata (garlic mustard), an extremely invasive species in the United States, can be toxic to their larvae. + +Description +Species belonging to the Brassicaceae are mostly annual, biennial, or perennial herbaceous plants, some are dwarf shrubs or shrubs, and very few vines. Although generally terrestrial, a few species such as water awlwort live submerged in fresh water. They may have a taproot or a sometimes woody caudex that may have few or many branches, some have thin or tuberous rhizomes, or rarely develop runners. Few species have multi-cellular glands. Hairs consist of one cell and occur in many forms: from simple to forked, star-, tree- or T-shaped, rarely taking the form of a shield or scale. They are never topped by a gland. The stems may be upright, rise up towards the tip, or lie flat, are mostly herbaceous but sometimes woody. Stems carry leaves or the stems may be leafless (in Caulanthus), and some species lack stems altogether. The leaves do not have stipules, but there may be a pair of glands at base of leaf stalks and flower stalks. The leaf may be seated or have a leafstalk. The leaf blade is usually simple, entire or dissected, rarely trifoliolate or pinnately compound. A leaf rosette at the base may be present or absent. The leaves along the stem are almost always alternately arranged, rarely apparently opposite. The stomata are of the anisocytic type. The genome size of Brassicaceae compared to that of other Angiosperm families is very small to small (less than 3.425 million base pairs per cell), varying from 150 Mbp in Arabidopsis thaliana and Sphaerocardamum spp., to 2375 Mbp Bunias orientalis. The number of homologous chromosome sets varies from four (n=4) in some Physaria and Stenopetalum species, five (n=5) in other Physaria and Stenopetalum species, Arabidopsis thaliana and a Mathiola species, to seventeen (n=17). About 35% of the species in which chromosomes have been counted have eight sets (n=8). Due to polyploidy, some species may have up to 256 individual chromosomes, with some very high counts in the North American species of Cardamine, such as C. diphylla. Hybridisation is not unusual in Brassicaceae, especially in Arabis, Rorippa, Cardamine and Boechera. Hybridisation between species originating in Africa and California, and subsequent polyploidisation is surmised for Lepidium species native to Australia and New Zealand. + +Inflorescence and flower +Flowers may be arranged in racemes, panicles, or corymbs, with pedicels sometimes in the axil of a bract, and few species have flowers that sit individually on flower stems that spring from the axils of rosette leaves. The orientation of the pedicels when fruits are ripe varies dependent on the species. The flowers are bisexual, star symmetrical (zygomorphic in Iberis and Teesdalia) and the ovary positioned above the other floral parts. Each flower has four free or seldom merged sepals, the lateral two sometimes with a shallow spur, which are mostly shed after flowering, rarely persistent, may be reflexed, spreading, ascending, or erect, together forming a tube-, bell- or urn-shaped calyx. Each flower has four petals, set alternating with the sepals, although in some species these are rudimentary or absent. They may be differentiated into a blade and a claw or not, and consistently lack basal appendages. The blade is entire or has an indent at the tip, and may sometimes be much smaller than the claws. The mostly six stamens are set in two whorls: usually the two lateral, outer ones are shorter than the four inner stamens, but very rarely the stamens can all have the same length, and very rarely species have different numbers of stamens such as sixteen to twenty four in Megacarpaea, four in Cardamine hirsuta, and two in Coronopus. The filaments are slender and not fused, while the anthers consist of two pollen producing cavities, and open with longitudinal slits. The pollen grains are tricolpate. The receptacle carries a variable number of nectaries, but these are always present opposite the base of the lateral stamens. + +Ovary, fruit and seed +There is one superior pistil that consists of two carpels that may either sit directly above the base of the stamens or on a stalk. It initially consists of only one cavity but during its further development a thin wall grows that divides the cavity, both placentas and separates the two valves (a so-called false septum). Rarely, there is only one cavity without a septum. The 2–600 ovules are usually along the side margin of the carpels, or rarely at the top. Fruits are capsules that open with two valves, usually towards the top. These are called silique if at least three times longer than wide, or silicle if the length is less than three times the width. The fruit is very variable in its other traits. There may be one persistent style that connects the ovary to the globular or conical stigma, which is undivided or has two spreading or connivent lobes. The variously shaped seeds are usually yellow or brown in color, and arranged in one or two rows in each cavity. The seed leaves are entire or have a notch at the tip. The seed does not contain endosperm. + +Differences with similar families +Brassicaceae have a bisymmetrical corolla (left is mirrored by right, stem-side by out-side, but each quarter is not symmetrical), a septum dividing the fruit, lack stipules and have simple (although sometimes deeply incised) leaves. The sister family Cleomaceae has bilateral symmetrical corollas (left is mirrored by right, but stem-side is different from out-side), stipules and mostly palmately divided leaves, and mostly no septum. Capparaceae generally have a gynophore, sometimes an androgynophore, and a variable number of stamens. + +Phytochemistry +Almost all Brassicaceae have C3 carbon fixation. The only exceptions are a few Moricandia species, which have a hybrid system between C3 and C4 carbon fixation, C4 fixation being more efficient in drought, high temperature and low nitrate availability. Brassicaceae contain different cocktails of dozens of glucosinolates. They also contain enzymes called myrosinases, that convert the glucosinolates into isothiocyanates, thiocyanates and nitriles, which are toxic to many organisms, and so help guard against herbivory. + +Taxonomy +Carl Linnaeus in 1753 regarded the Brassicaceae as a natural group, naming them "Klass" Tetradynamia. Alfred Barton Rendle placed the family in the order Rhoeadales, while George Bentham and Joseph Dalton Hooker in their system published from 1862 to 1883, assigned it to their cohort Parietales (now the class Violales). Following Bentham and Hooker, John Hutchinson in 1948 and again in 1964 thought the Brassicaceae to stem from near the Papaveraceae. In 1994, a group of scientists including Walter Stephen Judd suggested to include the Capparaceae in the Brassicaceae. Early DNA-analysis showed that the Capparaceae—as defined at that moment—were paraphyletic, and it was suggested to assign the genera closest to the Brassicaceae to the Cleomaceae. The Cleomaceae and Brassicaceae diverged approximately 41 million years ago. All three families have consistently been placed in one order (variably called Capparales or Brassicales). The APG II system merged Cleomaceae and Brassicaceae. Other classifications have continued to recognize the Capparaceae, but with a more restricted circumscription, either including Cleome and its relatives in the Brassicaceae or recognizing them in the segregate family Cleomaceae. The APG III system has recently adopted this last solution, but this may change as a consensus arises on this point. Current insights in the relationships of the Brassicaceae, based on a 2012 DNA-analysis, are summarized in the following tree. + +Relationships within the family +Early classifications depended on morphological comparison only, but because of extensive convergent evolution, these do not provide a reliable phylogeny. Although a substantial effort was made through molecular phylogenetic studies, the relationships within the Brassicaceae have not always been well resolved yet. It has long been clear that the Aethionema are sister of the remainder of the family. One analysis from 2014 represented the relation between 39 tribes with the following tree. + +Genera + +As of October 2023 Plants of the World Online accepts 346 genera. + +Etymology +The name Brassicaceae comes to international scientific vocabulary from Neo-Latin, from Brassica, the type genus, + -aceae, a standardized suffix for plant family names in modern taxonomy. The genus name comes from the Classical Latin word brassica, referring to cabbage and other cruciferous vegetables. The alternative older name, Cruciferae, meaning "cross-bearing", describes the four petals of mustard flowers, which resemble a cross. Cruciferae is one of eight plant family names, not derived from a genus name and without the suffix -aceae that are authorized alternative names. + +Distribution +Brassicaceae can be found almost on the entire land surface of the planet, but the family is absent from Antarctica, and also absent from some areas in the tropics i.e. northeastern Brazil, the Congo basin, Maritime Southeast Asia and tropical Australasia. The area of origin of the family is possibly the Irano-Turanian Region, where approximately 900 species occur in 150 different genera. About 530 of those 900 species are endemics. Next in abundance comes the Mediterranean Region, with around 630 species (290 of which are endemic) in 113 genera. The family is less prominent in the Saharo-Arabian Region—65 genera, 180 species of which 62 are endemic—and North America (comprising the North American Atlantic Region and the Rocky Mountain Floristic Region)—99 genera, 780 species of which 600 are endemic. South America has 40 genera containing 340 native species, Southern Africa 15 genera with over 100 species, and Australia and New-Zealand have 19 genera with 114 species between them. + +Ecology +Brassicaceae are almost exclusively pollinated by insects. A chemical mechanism in the pollen is active in many species to avoid selfing. Two notable exceptions are exclusive self-pollination in closed flowers in Cardamine chenopodifolia, and wind pollination in Pringlea antiscorbutica. Although it can be cross-pollinated, Alliaria petiolata (garlic mustard) is self-fertile. Most species reproduce sexually through seed, but Cardamine bulbifera produces gemmae and in others, such as Cardamine pentaphyllos, the coral-like roots easily break into segments, that will grow into separate plants. In some species, such as in the genus Cardamine, seed pods open with force and so catapult the seeds quite far. Many of these have sticky seed coats, assisting long distance dispersal by animals, and this may also explain several intercontinental dispersal events in the genus, and its near global distribution. Brassicaceae are common on serpentine and dolomite rich in magnesium. Over a hundred species in the family accumulate heavy metals, particularly zinc and nickel, which is a record percentage. Several Alyssum species can accumulate nickel up to 0.3% of their dry weight, and may be useful in soil remediation or even bio-mining. + +Brassicaceae contain glucosinolates as well as myrosinases inside their cells. When the cell is damaged, the myrosinases hydrolise the glucosinolates, leading to the synthesis of isothiocyanates, which are compounds toxic to most animals, fungi and bacteria. Some insect herbivores have developed counter adaptations such as rapid absorption of the glucosinates, quick alternative breakdown into non-toxic compounds and avoiding cell damage. In the whites family (Pieridae), one counter mechanism involves glucosinolate sulphatase, which changes the glucosinolate, so that it cannot be converted to isothiocyanate. A second is that the glucosinates are quickly broken down, forming nitriles. Differences between the mixtures of glucosinolates between species and even within species is large, and individual plants may produce in excess of fifty individual substances. The energy penalty for synthesising all these glucosinolates may be as high as 15% of the total needed to produce a leaf. Barbarea vulgaris (bittercress) also produces triterpenoid saponins. These adaptations and counter adaptations probably have led to extensive diversification in both the Brassicaceae and one of its major pests, the butterfly family Pieridae. A particular cocktail of volatile glucosinates triggers egg-laying in many species. Thus a particular crop can sometimes be protected by planting bittercress as a deadly bait, for the saponins kill the caterpillars, but the butterfly is still lured by the bittercress to lay its egg on the leaves. +A moth that feeds on a range of Brassicaceae is the diamondback moth (Plutella xylostella). Like the Pieridae, it is capable of converting isothiocyanates into less problematic nitriles. Managing this pest in crops became more complicated after resistance developed against a toxin produced by Bacillus thuringiensis, which is used as a wide spectrum biological plant protection against caterpillars. Parasitoid wasps that feed on such insect herbivores are attracted to the chemical compounds released by the plants, and thus are able to locate their prey. The cabbage aphid (Brevicoryne brassicae) stores glucosinolates and synthesises its own myrosinases, which may deter its potential predators. + +Since its introduction in the 19th century, Alliaria petiolata has been shown to be extremely successful as an invasive species in temperate North America due, in part, to its secretion of allelopathic chemicals. These inhibit the germination of most competing plants and kill beneficial soil fungi needed by many plants, such as many tree species, to successfully see their seedlings grow to maturity. The monoculture formation of an herb layer carpet by this plant has been shown to dramatically alter forests, making them wetter, having fewer and fewer trees, and having more vines such as poison ivy (Toxicodendron radicans). The overall herb layer biodiversity is also drastically reduced, particularly in terms of sedges and forbs. Research has found that removing 80% of the garlic mustard infestation plants did not lead to a particularly significant recovery of that diversity. Instead, it required around 100% removal. Given that not one of an estimated 76 species that prey on the plant has been approved for biological control in North America and the variety of mechanisms the plant has to ensure its dominance without them (e.g. high seed production, self-fertility, allelopathy, spring growth that occurs before nearly all native plants, roots that break easily when pulling attempts are made, a complete lack of palatability for herbivores at all life stages, etc.) it is unlikely that such a high level of control can be established and maintained on the whole. It is estimated that adequate control can be achieved with the introduction of two European weevils, including one that is monophagous. The USDA's TAG group has blocked these introductions since 2004. In addition to being invasive, garlic mustard also is a threat to native North American Pieris butterflies such as P. oleracea, as they preferentially oviposit on it, although it is toxic to their larvae. + +Invasive aggressive mustard species are known for being self-fertile, seeding very heavily with small seeds that have a lengthy lifespan coupled with a very high rate of viability and germination, and for being completely unpalatable to both herbivores and insects in areas to which they are not native. Garlic mustard is toxic to several rarer North American Pieris species. + +Uses + +This family includes important agricultural crops, among which many vegetables such as cabbage, broccoli, cauliflower, kale, Brussels sprouts, collard greens, Savoy, kohlrabi, and gai lan (Brassica oleracea), turnip, napa cabbage, bomdong, bok choy and rapini (Brassica rapa), rocket salad/arugula (Eruca sativa), garden cress (Lepidium sativum), watercress (Nasturtium officinale) and radish (Raphanus) and a few spices like horseradish (Armoracia rusticana), Brassica, wasabi (Eutrema japonicum), white, Indian and black mustard (Sinapis alba, Brassica juncea and B. nigra respectively). Vegetable oil is produced from the seeds of several species such as Brassica napus (rapeseed oil), perhaps providing the largest volume of vegetable oils of any species. Woad (Isatis tinctoria) was used in the past to produce a blue textile dye (indigo), but has largely been replaced by the same substance from unrelated tropical species like Indigofera tinctoria. + +Pringlea antiscorbutica, commonly known as Kerguelen cabbage, is edible, containing high levels of potassium. Its leaves contain a vitamin C-rich oil, a fact which, in the days of sailing ships, made it very attractive to sailors suffering from scurvy, hence the species name's epithet antiscorbutica, which means "against scurvy" in Low Latin. It was essential to the diets of the whalers on Kerguelen when pork, beef, or seal meat was used up. + +The Brassicaceae also includes ornamentals, such as species of Aethionema, Alyssum, Arabis, Aubrieta, Aurinia, Cheiranthus, Erysimum, Hesperis, Iberis, Lobularia, Lunaria, Malcolmia, and Matthiola. Honesty (Lunaria annua) is cultivated for the decorative value of the translucent remains of the fruits after drying. It can be a pest species in areas where it is not native. + +The small Eurasian weed Arabidopsis thaliana is widely used as model organism in the study of the molecular biology of flowering plants (Angiospermae). + +Some species are useful as food plants for Lepidoptera, such as certain wild mustard and cress species, such as Turritis glabra and Boechera laevigata that are utilized by several North American butterflies. + +Gallery + +References + +External links + BrassiBase, a collection of resources on Brassicaceae biology + +Further reading + + + +Brassicales families +Baseball statistics play an important role in evaluating the progress of a player or team. + +Since the flow of a baseball game has natural breaks to it, and normally players act individually rather than performing in clusters, the sport lends itself to easy record-keeping and statistics. Statistics have been recorded since the game's earliest beginnings as a distinct sport in the middle of the nineteenth century, and as such are extensively available from leagues such as the National Association of Professional Base Ball Players and the Negro leagues, although the consistency to which these records have been kept and the standards with respect to which they were calculated (and their accuracy) has varied. + +Since the National League (which along with the American League constitutes contemporary Major League Baseball) was founded in 1876, statistics in the most elite levels of professional baseball have been kept to a reasonably consistent standard which has continually evolved in tandem with advancement in available technology. + +Development +The practice of keeping records of player achievements was started in the 19th century by Henry Chadwick. Based on his experience with the sport of cricket, Chadwick devised the predecessors to modern-day statistics including batting average, runs scored, and runs allowed. + +Traditionally, statistics such as batting average (the number of hits divided by the number of at bats) and earned run average (the average number of earned runs allowed by a pitcher per nine innings) have dominated attention in the statistical world of baseball. However, the recent advent of sabermetrics has created statistics drawing from a greater breadth of player performance measures and playing field variables. Sabermetrics and comparative statistics attempt to provide an improved measure of a player's performance and contributions to his team from year to year, frequently against a statistical performance average. + +Comprehensive, historical baseball statistics were difficult for the average fan to access until 1951, when researcher Hy Turkin published The Complete Encyclopedia of Baseball. In 1969, Macmillan Publishing printed its first Baseball Encyclopedia, using a computer to compile statistics for the first time. Known as "Big Mac", the encyclopedia became the standard baseball reference until 1988, when Total Baseball was released by Warner Books using more sophisticated technology. The publication of Total Baseball led to the discovery of several "phantom ballplayers", such as Lou Proctor, who did not belong in official record books and were removed. + +Use +Throughout modern baseball, a few core statistics have been traditionally referenced – batting average, RBI, and home runs. To this day, a player who leads the league in all of these three statistics earns the "Triple Crown". For pitchers, wins, ERA, and strikeouts are the most often-cited statistics, and a pitcher leading his league in these statistics may also be referred to as a "triple crown" winner. General managers and baseball scouts have long used the major statistics, among other factors and opinions, to understand player value. Managers, catchers and pitchers use the statistics of batters of opposing teams to develop pitching strategies and set defensive positioning on the field. Managers and batters study opposing pitcher performance and motions in attempting to improve hitting. Scouts use stats when they are looking at a player who they may end up drafting or signing to a contract. + +Some sabermetric statistics have entered the mainstream baseball world that measure a batter's overall performance including on-base plus slugging, commonly referred to as OPS. OPS adds the hitter's on-base percentage (number of times reached base by any means divided by total plate appearances) to their slugging percentage (total bases divided by at-bats). Some argue that the OPS formula is flawed and that more weight should be shifted towards OBP (on-base percentage). The statistic wOBA (weighted on-base average) attempts to correct for this. + +OPS is also useful when determining a pitcher's level of success. "Opponent on-base plus slugging" (OOPS) is becoming a popular tool to evaluate a pitcher's actual performance. When analyzing a pitcher's statistics, some useful categories include K/9IP (strikeouts per nine innings), K/BB (strikeouts per walk), HR/9 (home runs per nine innings), WHIP (walks plus hits per inning pitched), and OOPS (opponent on-base plus slugging). + +However, since 2001, more emphasis has been placed on defense-independent pitching statistics, including defense-independent ERA (dERA), in an attempt to evaluate a pitcher's performance regardless of the strength of the defensive players behind them. + +All of the above statistics may be used in certain game situations. For example, a certain hitter's ability to hit left-handed pitchers might incline a manager to increase their opportunities to face left-handed pitchers. Other hitters may have a history of success against a given pitcher (or vice versa), and the manager may use this information to create a favorable +match-up. This is often referred to as "playing the percentages". + +Commonly used statistics +Most of these terms also apply to softball. Commonly used statistics with their abbreviations are explained here. The explanations below are for quick reference and do not fully or completely define the statistic; for the strict definition, see the linked article for each statistic. + +Batting statistics + 1B – Single: hits on which the batter reaches first base safely without the contribution of a fielding error + 2B – Double: hits on which the batter reaches second base safely without the contribution of a fielding error + 3B – Triple: hits on which the batter reaches third base safely without the contribution of a fielding error + AB – At bat: plate appearances, not including bases on balls, being hit by pitch, sacrifices, interference, or obstruction + AB/HR – At bats per home run: at bats divided by home runs + BA – Batting average (also abbreviated AVG): hits divided by at bats (H/AB) + BB – Base on balls (also called a "walk"): hitter not swinging at four pitches called out of the strike zone and awarded first base. + BABIP – Batting average on balls in play: frequency at which a batter reaches a base after putting the ball in the field of play.

An at bat is different from a plate appearance. A batter is credited with a plate appearance regardless of what happens during their turn at bat, but a batter is credited with an at bat only if that plate appearance does not have one of the results enumerated below. While at bats are used to calculate certain statistics, including batting average and slugging percentage, a player can qualify for the season-ending rankings in these categories only if they accumulate 502 plate appearances during the season. + +Batters will not receive credit for an at bat if their plate appearances end under the following circumstances: + They receive a base on balls (BB). + They are hit by a pitch (HBP). + They hit a sacrifice fly or a sacrifice bunt (also known as sacrifice hit). + They are awarded first base due to interference or obstruction, usually by the catcher. + They are replaced by another hitter before their at bat is completed, in which case the plate appearance and any related statistics go to the pinch hitter (unless they are replaced with two strikes and their replacement completes a strikeout, in which case the at bat and strikeout are charged to the first batter). +In addition, if the inning ends while they are still at bat (due to the third out being made by a runner caught stealing, for example), no at bat or plate appearance will result. + +Put shortly, an at bat is a specific type of plate appearance in which the batter puts the ball in play intending to get on base---it is why at bats, and not plate appearances, are used to calculate batting average, as plate appearances in general can result in many outcomes that don't involve putting the ball in play, and batting average specifically measures a batter's contact hitting. + +Rule 9.02(a)(1) of the official rules of Major League Baseball defines an at bat as: "Number of times batted, except that no time at bat shall be charged when a player: (A) hits a sacrifice bunt or sacrifice fly; (B) is awarded first base on four called balls; (C) is hit by a pitched ball; or (D) is awarded first base because of interference or obstruction[.]" + +Examples +An at bat is counted when: +The batter reaches first base on a hit +The batter reaches first base on an error +The batter is called out for any reason other than a sacrifice +There is a fielder's choice + +Records + +Pete Rose had 14,053 career at bats, the all-time major league and National League record. The American League record is held by Carl Yastrzemski, whose 11,988 career at bats were all in the AL. + +The single season record is held by Jimmy Rollins, who had 716 at bats in 2007; Willie Wilson, Ichiro Suzuki and Juan Samuel also had more than 700 at bats in a season. 14 players share the single game record of 11 at bats in a single game, all of which were extra inning games. In games of 9 innings or fewer, the record is 7 at bats and has occurred more than 200 times. + +The team record for most at bats in a single season is 5,781 by the 1997 Boston Red Sox. + +At bat as a phrase +"At bat", "up", "up at bat", and "at the plate" are all phrases describing a batter who is facing the pitcher. Note that just because a player is described as being "at bat" in this sense, he will not necessarily be given an at bat in his statistics; the phrase actually signifies a plate appearance (assuming it is eventually completed). This ambiguous terminology is usually clarified by context. To refer explicitly to a statistical "at bat", the term "official at bat" is sometimes used. + +"Time at bat" in the rulebook +Official Baseball Rule 5.06(c) provides that "[a] batter has legally completed his time at bat when he is put out or becomes a runner" (emphasis added). The "time at bat" defined in this rule is more commonly referred to as a plate appearance, and the playing rules (Rules 1 through 8) uses the phrase "time at bat" in this sense. In contrast, the scoring rules use the phrase "time at bat" to refer to the statistic at bat, defined in Rule 9.02(a)(1), but sometimes uses the phrase "official time at bat" or refers back to Rule 9.02(a)(1) when mentioning the statistic. The phrase "plate appearance" is used in Rules 9.22 and 9.23 dealing with batting titles and hitting streaks, and in Rule 5.10(g) comment regarding the Three-Batter Minimum: "[t]o qualify as one of three consecutive batters, the batter must complete his plate appearance, which ends only when the batter is put out or becomes a runner." The term is not elsewhere defined in the rulebook. + +See also +Batting order +At bats with runners in scoring position + +Notes + +References + +Batting statistics +Batting (baseball) +In baseball, an earned run is any run that was fully enabled by the offensive team's production in the face of competent play from the defensive team. Conversely, an unearned run is a run that would not have been scored without the aid of an error or a passed ball committed by the defense. + +An unearned run counts just as much as any other run for the purpose of determining the score of the game. However, it is "unearned" in that it was, in a sense, "given away" by the defensive team. + +Both total runs and earned runs are tabulated as part of a pitcher's statistics. However, earned runs are specially denoted because of their use in calculating a pitcher's earned run average (ERA), the number of earned runs allowed by the pitcher per nine innings pitched (i.e., averaged over a regulation game). Thus, in effect, the pitcher is held personally accountable for earned runs, while the responsibility for unearned runs is shared with the rest of the team. + +To determine whether a run is earned, the official scorer must reconstruct the inning as it would have occurred without errors or passed balls. + +Details +If no errors and no passed balls occur during the inning, all runs scored are automatically earned (assigned responsible to the pitcher(s) who allowed each runner to reach base). Also, in some cases, an error can be rendered harmless as the inning progresses. For example, a runner on first base advances to second on a passed ball and the next batter walks. Since the runner would now have been at second anyway, the passed ball no longer has any effect on the earned/unearned calculation. On the other hand, a batter/runner may make his entire circuit around the bases without the aid of an error, yet the run would be counted as unearned if an error prevented the third out from being made before he crossed the plate to score. + +An error made by the pitcher in fielding at his position is counted the same as an error by any other player. + +A run is counted as unearned when: + + A batter reaches base on an error (including catcher's interference) that would have retired the batter except for the error, and later scores a run in that inning by any means. + A batter hits a foul fly ball that is dropped by a fielder for an error, extending the at-bat, and later scores. In this case, the manner in which the batter reached base becomes irrelevant. + A baserunner remains on base or advances to the next base as the result of an error on a fielder's choice play that would put the baserunner out except for the error, and later scores. + A batter reaches first base on a passed ball (but not a wild pitch) and later scores. + A baserunner scores by any means after the third out would have been made except for an error other than catcher's interference. + A batter or runner advances one or more bases on an error or passed ball (but not a wild pitch) and scores on a play that would otherwise not have provided the opportunity to score. + Under either form of a WBSC tiebreaker in which each half-inning starts with the last one or two batters from the previous inning being placed on either second base (and if two runners, first base) to begin the inning, a run scored by these runners are unearned. If the runners are erased on a fielder's choice which places a batter on base, and the new batter-runner later scores, this would also be an unearned run. This rule was first implemented in WBSC competitions in 2008 and in the World Baseball Classic in 2013, with Major League Baseball adding it in 2020. + +While the inning is still being played, the second and the second-last scenario can cause a temporary situation where a run has already scored, but its earned/unearned status is not yet certain. Under the last circumstance, for example, with two outs, a runner on third base scores on a passed ball. For the time being, the run is unearned since the runner should still be at third. If the batter strikes out to end the inning, it will stay that way. If the batter gets a base hit, which would have scored the runner anyway, the run now becomes earned. + +Under the second circumstance, if there are runners on base and a batter hits a foul fly ball that is dropped, and then bats in the runners on base through a base hit (including a home run), the runs are unearned for the time being, as the runners should not have advanced. If the results of the remaining at-bats in the inning would not have scored the runners, the runs remain unearned. However, if results of subsequent at-bats would have scored the runs anyway, the runs would count as earned, unless they only would have scored as a result of a subsequent error or passed ball. + +A baserunner who reaches on catcher's interference and subsequently scores with two outs scores an unearned run, but baserunners who subsequently score after the runner who has reached on catcher's interference exclusively on clean plays score earned runs; the baserunner cannot be assumed to have been put out except for the error. (2019 MLB Rule 9.16(a)(4)). + +Neither the use of a pinch-runner to replace a baserunner who represents an unearned run nor the use of a pinch-hitter to continue the turn at bat of a batter who would be out except for an error transforms a run scored by such a person or his successors on base from an unearned run to an earned run. + +Pitching changes +When pitchers are changed in the middle of an inning, and one or more errors have already occurred, it is possible to have a run charged as earned against a specific pitcher, but unearned to the team. The simplest example is when the defensive team records two outs and makes an error on a play that would have been the third out. A new pitcher comes into the game, and the next batter hits a home run. The runner who reached on the error comes around to score, and his run is unearned to both the prior pitcher and the team. However, the run scored by the batter is counted as earned against the relief pitcher, but unearned to the team (since there should have already been three outs). Had the team not switched pitchers, neither run would be counted as an earned run because that pitcher should have already been out of that inning. + +A pitcher who is relieved mid-inning may be charged with earned runs equal to the number of batters who reached base while he was pitching, even if the specific batters he faced do not score. The batters he put on base may be erased by fielder's choice plays after he has been relieved by another pitcher, but if earned runs are scored in the inning the original pitcher is liable for as many earned runs as the number of batters he put on base. +Example: +On April 15, 2017, Detroit's Justin Verlander allowed the first two Cleveland batters in the 5th inning to reach base on base hits; Verlander was then relieved by Shane Greene. Greene walked the next batter to load the bases. The next batter hit a grounder and Miguel Cabrera threw home to force out the runner on third in a fielder's choice, so the bases remained loaded with one out. Greene struck out the next batter for the second out. Carlos Santana then hit a single that scored the runners from second and third (only one of whom was put on base by Verlander), and the runner from first was thrown out at the plate to end the inning. Since Verlander allowed two batters to reach base, he was charged with two earned runs, even though only one of the two specific batters he faced actually scored. + +When a pitching change occurs, the new pitcher is said to "inherit" any runners that are on base at the time, and if they later score, those runs are charged (earned or unearned) to the prior pitcher. Most box scores now list inherited runners, and the number that scored, as a statistic for the relief pitcher. + +See also +Baseball statistics +Earned run average +Run average + +References + +External links +Major League Baseball Official Rules + +Baseball terminology +Pitching statistics + +it:Media PGL +A base on balls (BB), also known as a walk, occurs in baseball when a batter receives four pitches during a plate appearance that the umpire calls balls, and is in turn awarded first base without the possibility of being called out. The base on balls is defined in Section 2.00 of baseball's Official Rules, and further detail is given in 6.08(a). Despite being known as a "walk", it is considered a faux pas for a professional player to literally walk to first base; the batter-runner and any advancing runners normally jog on such a play. + +The term "base on balls" distinguishes a walk from the other manners in which a batter can be awarded first base without liability to be put out (e.g., hit by pitch (HBP), catcher's interference). Though a base on balls, catcher's interference, or a batter hit by a pitched ball all result in the batter (and possibly runners on base) being awarded a base, the term "walk" usually refers only to a base on balls, and not the other methods of reaching base without the bat touching the ball. An important difference is that for a hit batter or catcher's interference, the ball is dead and no one may advance unless forced; the ball is live after a walk (see below for details). + +A batter who draws a base on balls is commonly said to have been "walked" by the pitcher. When the batter is walked, runners advance one base without liability to be put out only if forced to vacate their base to allow the batter to take first base. If a batter draws a walk with the bases loaded, all preceding runners are forced to advance, including the runner on third base who is forced to home plate to score a run; when a run is forced on a walk, the batter is credited with a run batted in per rule 9.04. + +Receiving a base on balls does not count as a hit or an at bat for a batter but does count as a time on base and a plate appearance. Therefore, a base on balls does not affect a player's batting average, but it can increase his on-base percentage. + +A hit by pitch is not counted statistically as a walk, though the effect is mostly the same, with the batter receiving a free pass to first base. One exception is that on hit-by-pitch, the ball is dead, and any runners attempting to steal on the play must return to their original base unless forced to the next base anyway. When a walk occurs, the ball is still live: any runner not forced to advance may nevertheless attempt to advance at his own risk, which might occur on a steal play, passed ball, or wild pitch. Also, because a ball is live when a base on balls occurs, runners on base forced to advance one base may attempt to advance beyond one base, at their own risk. The batter-runner himself may attempt to advance beyond first base, at his own risk. Rule 6.08 addresses this matter as well. An attempt to advance an additional base beyond the base awarded might occur when ball four is a passed ball or a wild pitch. + +History +In early baseball, there was no concept of a "ball." It was created by the NABBP in 1863, originally as a sort of unsportsmanlike-conduct penalty: "Should the pitcher repeatedly fail to deliver to the striker fair balls, for the apparent purpose of delaying the game, or for any other cause, the umpire, after warning him, shall call one ball, and if the pitcher persists in such action, two and three balls; when three balls shall have been called, the striker shall be entitled to the first base; and should any base be occupied at that time, each player occupying them shall be entitled to one base without being put out." Note that this rule in effect gave the pitcher 9 balls, since each penalty ball could only be called on a third offense. In 1869 the rule was modified so that only those baserunners forced to advance could advance. From 1871 through 1886, the batter was entitled to call "high" or "low," i.e. above or below the waist; a pitch which failed to conform was "unfair." Certain pitches were defined as automatic balls in 1872: any ball delivered over the batter's head, that hit the ground in front of home plate, was delivered to the opposite side from the batter, or came within one foot of him. In 1880, the National League changed the rules so that eight "unfair balls" instead of nine were required for a walk. In 1884, the National League changed the rules so that six balls were required for a walk. In 1886, the American Association changed the rules so that six balls instead of seven were required for a walk; however, the National League changed the rules so that seven balls were required for a walk instead of six. In 1887, the National League and American Association agreed to abide by some uniform rule changes, including, for the first time, a strike zone which defined balls and strikes by rule rather than the umpire's discretion, and decreased the number of balls required for a walk to five. In 1889, the National League and the American Association decreased the number of balls required for a walk to four. + +In 2017, Major League Baseball approved a rule change allowing for a batter to be walked intentionally by having the defending bench signal to the umpire. The move was met with some controversy. + +Intentional base on balls + +A subset of the base on balls, an intentional base on balls (IBB), or intentional walk, is when the defensive team intentionally issues a walk to the batter. In Major League Baseball and many amateur leagues, an intentional base on balls is signaled to the home plate umpire by the defensive team's manager holding up four fingers, at which point the batter is awarded first base without any further pitches being thrown. In some leagues and in Major League Baseball prior to 2017, an intentional base on balls is issued when the pitcher deliberately pitches the ball away from the batter four times (or as many times as needed to get to ball four if the decision to issue the intentional walk is made with one or more balls already on the count). As with any other walk, an intentional walk entitles the batter to first base without liability to be put out, and entitles any runners to advance if forced. + +Intentional walks are a strategic defensive maneuver, commonly done to bypass one hitter for one the defensive team believes is less likely to initiate a run-scoring play (e.g., a home run, sacrifice fly, or RBI base hit).

A hit batsman is awarded first base, provided that (in the plate umpire's judgment) he made an honest effort to avoid the pitch, although failure to do so is rarely called by an umpire. Being hit by a pitch is often caused by a batter standing too close to, or "crowding", home plate. + +The rule dates from 1887; before that, a pitch that struck the batter was merely a ball. + +Official rule +Per baseball official rule 5.05(b), a batter becomes a baserunner and is awarded first base when he or his equipment (except for his bat): +is touched by a pitched ball outside the strike zone, +and he attempts to avoid it (or had no opportunity to avoid it), +and he did not swing at the pitch. +If all these conditions are met, the ball is dead, and other baserunners advance if they are forced to vacate their base by the batter taking first. Rule 5.09(a) further clarifies that a hit by pitch is also called when a pitch touches a batter's clothing. + +In the case where a batter swings and the pitch hits him anyway, the ball is dead and a strike is called. If the batter does not attempt to avoid the pitch, he is not awarded first base, and the pitch is ruled either a strike if in the strike zone or a ball if out of the strike zone. Umpires rarely make this call. A famous instance of a non-hit by pitch was on May 31, 1968, when Don Drysdale hit Dick Dietz with a pitch that would have forced in a run and ended Drysdale's scoreless innings streak at 44. Umpire Harry Wendelstedt ruled that Dietz made no effort to avoid the pitch; Dietz proceeded to fly out, and Drysdale's scoreless streak continued to a then-record 58 innings. Another notable example was the first game of the 2022 World Series. In the bottom of the 10th inning, Philadelphia Phillies pitcher David Robertson was pitching to Houston Astros pinch hitter Aldemys Diaz. With 2 balls and no strikes, two out and two runners in scoring position, Robertson threw a pitch inside that struck Diaz's left arm. Home plate umpire James Hoye ruled that Diaz did not attempt to avoid the pitch and called the pitch a ball. Diaz, who had begun to take first base before Hoye called time, disputed the call, and would go on to ground out to end the game. + +A hit-by-pitch can also be called on a pitch that has first touched the ground before hitting the batter. Such a bouncing pitch is like any other, and if a batter is hit by such a pitch, he will be awarded first unless he made no attempt to avoid it (and he had an opportunity to avoid it). + +A batter hit by a pitch is not credited with a hit or at bat, but is credited with a time on base and a plate appearance; therefore, being hit by a pitch does not increase or decrease a player's batting average but does increase his on-base percentage. A batter hit by a pitch with the bases loaded is also credited with an RBI per MLB rule 10.04(a)(2). A pitch ruled a hit by pitch is recorded as a ball in the pitcher's pitch count, since by definition the ball must be outside the strike zone and not have been swung at. + +The rule awarding first base to a batter hit by a pitch was instituted in 1887. + +Tactical use + +Inside pitching is a common and legal tactic in baseball, and many players make use of brushback pitches, or pitches aimed underneath the chin, commonly referred to as "chin music", to keep players away from the plate. "Headhunter" is a common term for pitchers who have a reputation for throwing these kinds of pitches. However, throwing at a batter intentionally is illegal, and can be very dangerous. When an umpire suspects that a pitcher has thrown at a batter intentionally, but is not certain, a warning is issued to the pitcher and the managers of both teams. From that point on, any pitch thrown at a batter can cause the pitcher and the manager of the offending team to be ejected immediately from the game. Serious offenses such as a ball thrown at the head (called a beanball) can result in the immediate ejection of the pitcher, and the manager if he ordered the beanball, even without a warning. If the umpire is certain that the pitcher intentionally hit the batter with the pitch, the pitcher is ejected from the game with no warning. This infamously happened on August 15, 2018, when José Ureña was ejected from a game against the Atlanta Braves after hitting Ronald Acuña Jr. on the elbow with the first pitch of the game, which led to the Braves' and Marlins' benches emptying. + +Occasionally, if a player is acting rude or unsportsmanlike, or having an extraordinarily good day, the pitcher may intentionally hit the batter, disguising it as a pitch that accidentally slipped his control. Managers may also order a pitcher to throw such a pitch (sometimes called a "plunking"). These pitches are typically aimed at the lower back and slower than normal, designed to send a message more than anything else. The opposing team usually hits a batter in retaliation for this act. The plunkings generally end there because of umpire warnings, but in some cases things can get out of hand, and sometimes they lead to the batter charging the mound, bench-clearing brawls, and several ejections. + +Records + +Korea Baseball Organization third baseman Choi Jeong holds the most hit by pitch with 294. It is also the world record. He surpassed the 287 hit by pitch held by Hughie Jennings in 2021. +The all-time record for a player being hit by a pitch in MLB is held by Jennings, who was hit by 287 pitches between 1891 and 1903. The modern-era record is held by Craig Biggio of the Houston Astros, who had 285 as of the end of the 2007 season when he retired. Prior to Biggio, the modern-era record belonged to Don Baylor, who was hit 267 times. + +The all-time single-season record also belongs to Jennings, who was hit 51 times during the 1896 season. Ron Hunt of the 1971 Montreal Expos was hit 50 times during that year, the modern-era record. The single-game record is three, held by numerous players. + +The all-time record for pitchers is held by Gus Weyhing with 277 (1887–1901). The modern-era career pitching record for most hit batsmen is 205 by Hall-of-Famer Walter Johnson. The season record is 54 by Phil Knell in 1891, and the game record is six, held by Ed Knouff and John Grimes. +Brady Anderson was the first player to be hit by a pitch two times in the same inning in an American League game. On April 25, 2014, Brandon Moss became the second when he was hit twice in the top of the 9th inning by Houston Astros pitchers. Five players have been hit by a pitch twice in the same inning in the National League. On September 1, 2021, Austin Adams became the first pitcher hitting batters 20 or more times with 120 or less IPs in a season. Ed Doheny hit batters 22 times in 133.2 IP in 1900. + +Three times has a perfect game been broken up by the 27th batter being hit by pitch. Hooks Wiltse, Max Scherzer, and Joe Musgrove hold this rare feat. All three finished with no-hitters after the hit by pitch. Scherzer's team was leading 6–0 and Musgrove's 3–0 when they pitched their no-hitters, but Wiltse's team was scoreless through 9; he pitched a 10-inning 1–0 no-hitter. The record for most hit batters in a no-hitter is three, held by Chris Heston of the San Francisco Giants for his 2015 effort against the New York Mets. + +Postseason career records are held by Greg Maddux and Tim Wakefield—each of whom hit 9 batters—and Shane Victorino, who was hit by pitch 11 times. + +Dangers + +One major league player died as a result of being struck by a pitch: Ray Chapman of the Cleveland Indians was hit in the head by Carl Mays on August 16, 1920, and died the next morning. + +Serious injuries may result from being hit by a pitch, even when wearing a batting helmet. On August 18, 1967, Boston Red Sox batter Tony Conigliaro was hit almost directly in the left eye by a fastball thrown by Jack Hamilton of the California Angels. His cheekbone was shattered; he nearly lost the sight of the eye, was unable to play for over a year, and never regained his earlier batting ability. Batting helmets at the time were not required to have an "ear flap"; it was not until 2002 that all Major League batters were required to wear helmets with side-protection. Ron Santo was the first player to wear a helmet with an improvised ear-flap, in 1966. He had it made after he was struck by a pitch from Jack Fisher that briefly knocked him unconscious and put him on the Disabled List for two weeks with a fractured cheekbone. On September 28, 1995, Kirby Puckett, of the Minnesota Twins, was struck in the cheek by a Dennis Martínez fastball, breaking his jaw and loosening two teeth. It would be his last regular-season game; during spring training the following year he developed glaucoma, which ended his career. Most recently, Mike Piazza, then of the New York Mets, was hit in the head by a pitch from Julián Tavárez of the St. Louis Cardinals on September 10, 2005. His helmet shattered, and he suffered a concussion. Other relatively minor injuries that are possible include broken fingers or hands, broken feet, broken ribs, injuries to the knee, or groin injuries. + +Legal interpretation + +Since inside pitching is a legitimate tactic in baseball, courts have recognized that being hit by a pitch is an inherent risk of the game, so that players cannot sue for any resulting injuries. On April 6, 2006, in a case arising from a game involving community college baseball teams, the Supreme Court of California ruled that baseball players in California assume the risk of being hit by baseballs even if the balls were intentionally thrown so as to cause injury. In the court's words: "For better or worse, being intentionally thrown at is a fundamental part and inherent risk of the sport of baseball. It is not the function of tort law to police such conduct." + +References + +External links + + List of all-time HBP leaders + + Article on changing HBP rates in The Hardball Times + +Baseball rules +Baseball pitching +Baseball terminology +Batting statistics +Pitching statistics +In baseball statistics, a hit (denoted by H), also called a base hit, is credited to a batter when the batter safely reaches or passes first base after hitting the ball into fair territory with neither the benefit of an error nor a fielder's choice. + +Scoring a hit +To achieve a hit, the batter must reach first base before any fielder can either tag him with the ball, throw to another player protecting the base before the batter reaches it, or tag first base while carrying the ball. The hit is scored the moment the batter reaches first base safely; if he is put out while attempting to stretch his hit to a double or triple or home run on the same play, he still gets credit for a hit (according to the last base he reached safely on the play). + +If a batter reaches first base because of offensive interference by a preceding runner (including if a preceding runner is hit by a batted ball), he is also credited with a hit. + +Types of hits +A hit for one base is called a single, for two bases a double, and for three bases a triple. A home run is also scored as a hit. Doubles, triples, and home runs are also called extra base hits. + +An "infield hit" is a hit where the ball does not leave the infield. Infield hits are uncommon by nature, and most often earned by speedy runners. + +Pitching a no-hitter +A no-hitter is a game in which one of the teams prevented the other from getting a hit. Throwing a no-hitter is rare and considered an extraordinary accomplishment for a pitcher or pitching staff. In most cases in the professional game, no-hitters are accomplished by a single pitcher who throws a complete game. A pitcher who throws a no-hitter could still allow runners to reach base safely, by way of walks, errors, hit batsmen, or batter reaching base due to interference or obstruction. If the pitcher allows no runners to reach base in any manner whatsoever (hit, walk, hit batsman, error, etc.), the no-hitter is a perfect game. + +1887 discrepancy + +In 1887, Major League Baseball counted bases on balls (walks) as hits. The result was skyrocketing batting averages, including some near .500; Tip O'Neill of the St. Louis Browns batted .485 that season, which would still be a major league record if recognized. The experiment was abandoned the following season. + +There is controversy regarding how the records of 1887 should be interpreted. The number of legitimate walks and at-bats are known for all players that year, so computing averages using the same method as in other years is straightforward. In 1968, Major League Baseball formed a Special Baseball Records Committee to resolve this (and other) issues. The Committee ruled that walks in 1887 should not be counted as hits. In 2000, Major League Baseball reversed its decision, ruling that the statistics which were recognized in each year's official records should stand, even in cases where they were later proven incorrect. Most current sources list O'Neill's 1887 average as .435, as calculated by omitting his walks. He would retain his American Association batting championship. However, the variance between methods results in differing recognition for the 1887 National League batting champion. Cap Anson would be recognized, with his .421 average, if walks are included, but Sam Thompson would be the champion at .372 if they are not. + +Major League Baseball rules +The official rulebook of Major League Baseball states in Rule 10.05: +(a) The official scorer shall credit a batter with a base hit when: +(1) the batter reaches first base (or any succeeding base) safely on a fair ball that settles on the ground, that touches a fence before being touched by a fielder or that clears a fence; +(2) the batter reaches first base safely on a fair ball hit with such force, or so slowly, that any fielder attempting to make a play with the ball has no opportunity to do so; +Rule 10.05(a)(2) Comment: The official scorer shall credit a hit if the fielder attempting to handle the ball cannot make a play, even if such fielder deflects the ball from or cuts off another fielder who could have put out a runner. +(3) the batter reaches first base safely on a fair ball that takes an unnatural bounce so that a fielder cannot handle it with ordinary effort, or that touches the pitcher's plate or any base (including home plate) before being touched by a fielder and bounces so that a fielder cannot handle the ball with ordinary effort; +(4) the batter reaches first base safely on a fair ball that has not been touched by a fielder and that is in fair territory when the ball reaches the outfield, unless in the scorer's judgment the ball could have been handled with ordinary effort; +(5) a fair ball that has not been touched by a fielder touches a runner or an umpire, unless a runner is called out for having been touched by an Infield Fly, in which case the official scorer shall not score a hit; or +(6) a fielder unsuccessfully attempts to put out a preceding runner and, in the official scorer's judgment, the batter-runner would not have been put out at first base by ordinary effort. +Rule 10.05(a) Comment: In applying Rule 10.05(a), the official scorer shall always give the batter the benefit of the doubt.

An official Major League Baseball (MLB) statistic since 1984, it is sometimes referred to as on-base average (OBA), as it is rarely presented as a true percentage. + +Generally defined as "how frequently a batter reaches base per plate appearance", OBP is specifically calculated as the ratio of a batter's times on base (the sum of hits, bases on balls, and times hit by pitch) to the sum of at bats, bases on balls, hit by pitch, and sacrifice flies. OBP does not credit the batter for reaching base on fielding errors, fielder's choice, uncaught third strikes, fielder's obstruction, or catcher's interference. + +OBP is added to slugging average (SLG) to determine on-base plus slugging (OPS). + +The OBP of all batters faced by one pitcher or team is referred to as "on-base against". + +On-base percentage is calculable for professional teams dating back to the first year of National Association of Professional Base Ball Players competition in 1871, because the component values of its formula have been recorded in box scores ever since. + +History +The statistic was invented in the late 1940s by Brooklyn Dodgers statistician Allan Roth with then-Dodgers general manager Branch Rickey. In 1954, Rickey, who was then the general manager of the Pittsburgh Pirates, was featured in a Life Magazine graphic in which the formula for on-base percentage was shown as the first component of an all-encompassing "offense" equation. However, it was not named as on-base percentage, and there is little evidence that Roth's statistic was taken seriously at the time by the baseball community at large. + +On-base percentage became an official MLB statistic in 1984. Its perceived importance jumped after the influential 2003 book Moneyball highlighted Oakland Athletics general manager Billy Beane's focus on the statistic. Many baseball observers, particularly those influenced by the field of sabermetrics, now consider on-base percentage superior to the statistic traditionally used to measure offensive skill, batting average, which accounts for hits but ignores other ways a batter can reach base. + +Overview +Traditionally, players with the best on-base percentages bat as leadoff hitter, unless they are power hitters, who traditionally bat slightly lower in the batting order. The league average for on-base percentage in Major League Baseball has varied considerably over time; at its peak in the late 1990s, it was around .340, whereas it was typically .300 during the dead-ball era. On-base percentage can also vary quite considerably from player to player. The highest career OBP of a batter with more than 3,000 plate appearances is .482 by Ted Williams. The lowest is by Bill Bergen, who had an OBP of .194. + +On-base percentage is calculated using this formula: + +where + +H = Hits +BB = Bases on Balls (Walks) +HBP = Hit By Pitch +AB = At bat +SF = Sacrifice fly + +In certain unofficial calculations, the denominator is simplified and replaced by Plate Appearance (PA); however, the calculation PAs includes certain infrequent events that will slightly lower the calculated OBP (i.e. catcher's interference, and sacrifice bunts). Sacrifice bunts are excluded from consideration on the basis that they are usually imposed by the manager with the expectation that the batter will not reach base, and thus do not accurately reflect the batter's ability to reach base when attempting to do so. This is in contrast with the sacrifice fly, which is generally unintentional; the batter was trying for a hit. + +All-time leaders + +Single-season leaders + +See also + +List of Major League Baseball career on-base percentage leaders +Moneyball: The Art of Winning an Unfair Game + +Notes + +References + +Batting statistics +Baseball terminology +Percentages +In baseball, a sacrifice fly (sometimes abbreviated to sac fly) is defined by Rule 9.08(d): +"Score a sacrifice fly when, before two are out, the batter hits a ball in flight handled by an outfielder or an infielder running in the outfield in fair or foul territory that + is caught, and a run scores after the catch, or + is dropped, and a runner scores, if in the scorer's judgment the runner could have scored after the catch had the fly ball been caught." + +They are so named because the batter allows a teammate to score a run, while "sacrificing" his or her ability to do so. They are traditionally recorded in box scores with the designation "SF". + +Rules + +As addressed within Rule 9.02(a)(1) of the Official Baseball Rules a sacrifice fly is not counted as a time at bat for the batter, though the batter is credited with a run batted in. The same is true with a bases-loaded walk. + +The purpose of not counting a sacrifice fly as an at-bat is to avoid penalizing hitters for a successful action. The sacrifice fly is one of two instances in baseball where a batter is not charged with a time at bat after putting a ball in play; the other is the sacrifice hit (also known as a sacrifice bunt). But, while a sacrifice fly does not affect a player's batting average, it counts as a plate appearance and lowers the on-base percentage. A player on a hitting streak will have end it with no official at-bats but a sacrifice fly. + +Unlike a sacrifice bunt, which may be scored if a runner advances from any base to any base, a sacrifice fly is only credited if a runner scores on the play. Therefore, when a runner on first or second base tags on a fly ball and advances no further than third base, no sacrifice is given and the batter is charged with an at-bat. Also, if a runner tags and advances from second base (or, theoretically, from first base) all the way to home and scores (without an intervening error) the batter is credited with a sacrifice fly, as well as a second RBI if a runner on third also scores. At the professional level this will only typically occur in unusual circumstances that prevent the defense from making an immediate throw back to the infield, such as an outfielder colliding with the wall while making a catch on the warning track. + +The sacrifice fly is credited even if another runner is put out so long as the run scores. The sacrifice fly is credited on a dropped ball even if another runner is forced out by reason of the batter becoming a runner. + +On any fly ball, a runner can initiate an attempt to advance bases as soon as a fielder touches the ball by tagging up, even before the fielder has full control of the ball. + +Records +The most sacrifice flies by a team in one game in Major League Baseball (MLB) is five; the record was established by the Seattle Mariners in 1988, tied by the Colorado Rockies in 2006, and tied again by the Mariners in 2008. + +Five MLB teams have collected three sacrifice flies in an inning: the Chicago White Sox (fifth inning, July 1, 1962 against the Cleveland Indians); the New York Yankees twice (fourth inning, June 29, 2000 against the Detroit Tigers and third inning, August 19, 2000 against the Anaheim Angels); the New York Mets (second inning, June 24, 2005 against the Yankees); and the Houston Astros (seventh inning, June 26, 2005 against the Texas Rangers). In these cases one or more of the flies did not result in a putout due to an error. + +Since the rule was reinstated in its present form in MLB in 1954, Gil Hodges of the Dodgers holds the record for most sacrifice flies in one season with 19, in 1954; Eddie Murray holds the MLB record for most sacrifice flies in a career with 128. + +As of the end of the 2021 Major League Baseball season, the ten players who had hit the most sacrifice flies were as follows: + + Eddie Murray (128) + Cal Ripken Jr. (127) + Robin Yount (123) + Hank Aaron (121) + Frank Thomas (121) + George Brett (120) + Rubén Sierra (120) + Rafael Palmeiro (119) + Rusty Staub (119) + Andre Dawson (118) + +Only once has the World Series been won on a sac fly. In 1912, Larry Gardner of the Boston Red Sox hit a fly ball off a pitch from the New York Giants' Christy Mathewson. Steve Yerkes tagged up and scored from third base to win game 8 in the tenth inning and take the series for the Red Sox. + +History +Batters have not been charged with a time at-bat for a sacrifice hit since 1893, but baseball has changed the sacrifice fly rule multiple times. The sacrifice fly as a statistical category was instituted in 1908, only to be discontinued in 1931. The rule was again adopted in 1939, only to be eliminated again in 1940, before being adopted for the last time in 1954. For some baseball fans, it is significant that the sacrifice-fly rule was eliminated in 1940 because, in 1941, Ted Williams was hitting .39955 on the last day of the season and needed one hit in a doubleheader against the Philadelphia A's to become the first hitter since Bill Terry in 1930 to hit .400. He got six hits, finishing with an official .406 average, the last player in over 80 years to bat .400 or more in the American or National League. In his book Baseball and Other Matters in 1941 author Robert Creamer, citing estimates, points out that if Williams' 14 at-bats on sacrifice flies that year were deducted from the 456 official at-bats he was charged with, his final average in 1941 would have been .419. + +References + +External links +MLB Official Rules from the Major League Baseball website +Baseball Rules Chronology, from Baseball Library +The Sacrifice Fly, from the SABR web site (Research Journals Archive) + +Baseball plays +Batting (baseball) +On-base plus slugging (OPS) is a sabermetric baseball statistic calculated as the sum of a player's on-base percentage and slugging percentage. The ability of a player both to get on base and to hit for power, two important offensive skills, are represented.

Baseball journalist Peter Gammons used and evangelized the statistic, and other writers and broadcasters picked it up. The popularity of OPS gradually spread, and by 2004 it began appearing on Topps baseball cards. + +OPS was formerly sometimes known as production. For instance, production was included in early versions of Thorn's Total Baseball encyclopedia, and in the Strat-O-Matic Computer Baseball game.

An OPS+ of 150 or more is excellent and 125 very good, while an OPS+ of 75 or below is poor. + +The basic equation for OPS+ is + +where *lgOBP is the park adjusted OBP of the league (not counting pitchers hitting) and *lgSLG is the park adjusted SLG of the league. + +A common misconception is that OPS+ closely matches the ratio of a player's OPS to that of their league. In fact, due to the additive nature of the two components in OPS+, a player with an OBP and SLG both 50% better than league average in those metrics will have an OPS+ of 200 (twice the league average OPS+) while still having an OPS that is only 50% better than the average OPS of the league. It would be a better (although not exact) approximation to say that a player with an OPS+ of 150 produces 50% more runs, in a given set of plate appearances, as a player with an OPS+ of 100 (though see clarification above, under "History"). + +Leaders in OPS+ +Through the end of the 2019 season, the career top twenty leaders in OPS+ (minimum 3,000 plate appearances) were: + +Babe Ruth, 206 +Ted Williams, 190 +Barry Bonds, 182 +Lou Gehrig, 179 +Mike Trout, 176 +Rogers Hornsby, 175 +Mickey Mantle, 172 +Dan Brouthers, 171 +Joe Jackson, 170 +Ty Cobb, 168 +Pete Browning, 163 +Jimmie Foxx, 163 +Mark McGwire, 163 +Dave Orr, 162 +Stan Musial, 159 +Hank Greenberg, 158 +Johnny Mize, 158 +Tris Speaker, 157 +Dick Allen, 156 +Willie Mays, 156 +Frank Thomas 156 + +The only purely right-handed batters to appear on this list are Browning, Hornsby, Foxx, Orr, Trout, McGwire, Allen, Mays, and Thomas.

He did not play nearly so well when this rule was removed, although injuries may have been mostly to blame, as his fielding statistics similarly declined. + +If Dunlap's and Barnes's seasons were to be eliminated from the list, two other Ruth seasons (1926 and 1927) would be on the list. This would also eliminate the only two right-handed batters in the list. + +Criticism +Despite its simple calculation, OPS is a controversial measurement. OPS weighs on-base percentage and slugging percentage equally. However, on-base percentage correlates better with scoring runs. Statistics such as wOBA build on this distinction using linear weights. Additionally, the components of OPS are not typically equal (league-average slugging percentages are usually 75–100 points higher than league-average on-base percentages). As a point of reference, the OPS for all of Major League Baseball in 2019 was .758. + +See also + + Sabermetrics + Gross production average + +Notes + +References + + + +Batting statistics +In baseball, a stolen base occurs when a runner advances to a base unaided by other actions and the official scorer rules that the advance should be credited to the action of the runner. The umpires determine whether the runner is safe or out at the next base, but the official scorer rules on the question of credit or blame for the advance under Rule 10 (Rules of Scoring) of the MLB's Official Rules. + +A stolen base most often occurs when a base runner advances to the next base while the pitcher is pitching the ball to home plate. + +Successful base stealers must be fast and have good timing. + +Background +Ned Cuthbert, playing for the Philadelphia Keystones in either 1863 or 1865, was the first player to steal a base in a baseball game, although the term stolen base was not used until 1870. For a time in the 19th century, stolen bases were credited when a baserunner reached an extra base on a base hit from another player. For example, if a runner on first base reached third base on a single, it counted as a steal. In 1887, Hugh Nicol set a still-standing Major League record with 138 stolen bases, many of which would not have counted under modern rules. Modern steal rules were fully implemented in 1898. + +Base stealing was popular in the game's early decades, with speedsters such as Ty Cobb and Clyde Milan stealing nearly 100 bases in a season. But the tactic fell into relative disuse after Babe Ruth introduced the era of the home run – in 1955, for example, no one in baseball stole more than 25 bases, and Dom DiMaggio won the AL stolen base title in 1950 with just 15. However, in the late 1950s and early 1960s, base-stealing was brought back to prominence primarily by Luis Aparicio and Maury Wills, who broke Cobb's modern single-season record by stealing 104 bases in 1962. Wills’ record was broken in turn by Lou Brock in 1974 and Rickey Henderson in 1982. The stolen base remained a popular tactic through the 1980s, perhaps best exemplified by Vince Coleman and the St. Louis Cardinals, but began to decline again in the 1990s as the frequency of home runs reached record heights and the steal-friendly artificial turf ballparks began to disappear. + +Base stealing is an important characteristic of the "small ball" managing style (or "manufacturing runs"). Such managers emphasize "doing the little things" (including risky running plays like base-stealing) to advance runners and score runs, often relying on pitching and defense to keep games close. The Los Angeles Dodgers of the 1960s, led by pitcher Sandy Koufax and speedy shortstop Maury Wills, were a successful example of this style. The antithesis of this is reliance on power hitting, exemplified by the Baltimore Orioles of the 1970s, which aspired to score most of its runs via home runs. Often the "small ball" model is associated with the National League, while power hitting is associated with the American League. However, some successful recent American League teams, including the 2002 Anaheim Angels, the 2001 Seattle Mariners the 2005 Chicago White Sox, and the 2015 Kansas City Royals have excelled at "small ball." The Royals in particular embodied this style within the last decade, leading the league in stolen bases but finishing last in home runs in 2013 and 2014, leading to a berth in two consecutive World Series, one of which they won. Successful teams often combine both styles, with speedy runners complementing power hitters—such as the 2005 White Sox, who hit 200 home runs, which was fifth most in the majors, and had 137 stolen bases, which was fourth. + +Base-stealing technique +Baseball's Rule 8 (The Pitcher) specifies the pitching procedure in detail. For example, in the Set Position, the pitcher must "com[e] to a complete stop"; thereafter, "any natural motion associated with his delivery of the ball to the batter commits him to the pitch without alteration or interruption." A runner intending to "steal on the pitcher" breaks for the next base the moment the pitcher commits to pitch to home plate. The pitcher cannot abort the pitch and try to put the runner out; this is a balk under Rule 8. + +If the runner breaks too soon (before the pitcher is obliged to complete a pitch), the pitcher may throw to a base rather than pitch, and the runner is usually picked off by being tagged out between the bases. Past this moment, any delay in the runner's break makes it more likely that the catcher, after receiving the pitch, will be able to throw the runner out at the destination base. + +Before the pitch, the runner takes a lead, walking several steps away from the base as a head start toward the next base. Even a runner who does not intend to steal takes a secondary lead of a few more steps, once the pitcher has legally committed to complete the pitch. + +The pitcher may throw to the runner's base. The runner must return to that base or risk being tagged out. As well as putting the runner out, an underlying goal is to dissuade the runner from too big a lead; that is, to hold the runner on the original base. (Historically, this gambit could be used without limit. An MLB rules change in 2023 limited the pitcher to two throws; the pitcher must then pitch to the batter.) + +The more adept base stealers are proficient at reading the pickoff, meaning that they can detect certain tells (tell-tale signs) in a pitcher's pre-pitch movements or mannerisms that indicate the pickoff attempt is or is not imminent. For example, one experienced base stealer noted that careless pitchers dig the toes on their back foot into the ground when they are about to pitch in order to get a better push off, but when they intend to turn and throw a pickoff, they do not. + +If a batted ball is caught on the fly, the runner must return to his original base. In this case, a runner trying to steal is more likely to be caught off his original base, resulting in a double play. This is a minor risk of a steal attempt. It is offset by the fact that a ground ball double play is less likely. + +Plays involving baserunning +In the hit-and-run play, coaches coordinate the actions of runner and batter. The runner tries to steal and the batter swings at almost any pitch, if only to distract the catcher. If the batter makes contact, the runner has a greater chance of reaching the next base; if the batter gets a base hit, the runner will likely be able to take an extra base. If the batter fails to hit the ball, the hit-and-run becomes a pure steal attempt. + +The less common cousin to the hit and run is the "run and hit" play. In the run and hit, the base runner attempts to advance when the pitcher commits the pitch to home plate, but the batter is instead directed to exercise his judgement as to whether or not to swing at the pitch. If the batter feels it is not advantageous to swing, AND he believes the base runner is very likely to succeed in the steal attempt, he does not swing. This play is typically utilized with elite base stealers and skilled batters only, wherein a highly experienced batsman is trusted to decide whether or not to "protect" the base runner. If the batter chooses not to swing, it becomes a pure steal attempt. + +In the delayed steal, the runner does not take advantage of the pitcher's duty to complete a pitch, but relies on surprise and takes advantage of any complacency by the fielders. The runner gives the impression he is not trying to steal, and does not break for the next base until the ball crosses the plate. It is rare for Major League defenses to be fooled, but the play is used effectively at the college level. The first delayed steal on record was performed by Miller Huggins in 1903. The delayed steal was famously practiced by Eddie Stanky of the Brooklyn Dodgers. + +Second base is the base most often stolen, because once a runner is on second base he is considered to be in scoring position, meaning that he is expected to be able to run home and score on most routine singles hit into the outfield. Second base is also the easiest to steal, as it is farthest from home plate and thus a longer throw from the catcher is required to prevent it. Third base is a shorter throw for the catcher, but the runner is able to take a longer lead off second base and can leave for third base earlier against a left-handed pitcher. A steal of home plate is the riskiest, as the catcher only needs to tag out the runner after receiving the ball from the pitcher. It is difficult for the runner to cover the distance between the bases before the ball arrives home. Ty Cobb holds the records for most steals of home in a single season (8) as well as for a career (54). Steals of home are not officially recorded statistics, and must be researched through individual game accounts. Thus Cobb's totals may be even greater than is recorded. Jackie Robinson famously stole home in Game 1 of the 1955 World Series. Thirty-five games have ended with a runner stealing home, but only two have occurred since 1980. In a variation on the steal of home, the batter is signaled to simultaneously execute a sacrifice bunt, which results in the squeeze play. The suicide squeeze is a squeeze in which the runner on third begins to steal home without seeing the outcome of the bunt; it is so named because if the batter fails to bunt, the runner will surely be out. In contrast, when the runner on third does not commit until seeing that the ball is bunted advantageously, it is called a safety squeeze. + +In more recent years, most steals of home involve a delayed double steal, in which a runner on first attempts to steal second, while the runner on third breaks for home as soon as the catcher throws to second base. If it is important to prevent the run from scoring, the catcher may hold on to the ball (conceding the steal of second) or may throw to the pitcher; this may deceive the runner at third and the pitcher may throw back to the catcher for the out. + +Statistics + +In baseball statistics, stolen bases are denoted by "SB". Attempts to steal that result in the baserunner being out are caught stealing ("CS"). The sum of these statistics is steal attempts. Successful steals as a percentage of total steal attempts is called the success rate. + +The rule on stolen bases states that: +Advances that are credited to some other play are not steal attempts. For example, on a wild pitch or a passed ball, the official scorer must notice whether the runner broke for the next base before the pitch got away. +As usual, statistics in the case of a defensive error are based on error-free play. If a runner would have been out, but for the error, it is scored as "caught stealing, safe on the error." A catcher does not commit an error by throwing poorly to the destination base, but if any runner takes an extra base on the bad throw, it is "stolen base plus error." +There is no steal attempt on a dead ball, whether the runner is sent back to the original base (as on a foul ball) or is awarded the next base (as on a hit batsman). On a base award when the ball is live (such as a walk), the runner could make a steal attempt beyond the base awarded. + Cases where the defense intentionally allows the runner to advance without attempting to put him out are scored as defensive indifference, also called fielder's indifference, and do not count as stolen bases. This is usually only scored late in games when it is clear that the defense's priority is getting the batter out. The lack of a putout attempt does not by itself indicate defensive indifference; the official scorer must also factor in the game situation and the defensive players' actions. + +Relative skill at stealing bases can be judged by evaluating either a player's total number of steals or the success rate. Noted statistician Bill James has argued that unless a player has a high success rate (67–70% or better), attempting to steal a base is detrimental to a team. + +Comparing skill against players from other eras is problematic, because the definition has not been constant. Caught stealing was not recorded regularly until the middle of the 20th century. Ty Cobb, for example, was known as a great base-stealer, with 892 steals and a success rate of over 83%. However, the data on Cobb's caught stealing is missing from 12 seasons, strongly suggesting he was unsuccessful many more times than his stats indicate. Carlos Beltrán, with 286 steals, has the highest career success rate of all players with over 300 stolen base attempts, at 88.3%. + +Evolution of rules and scoring + +The first mention of the stolen base as a statistic was in the 1877 scoring rules adopted by the National League, which noted credit toward a player's total bases when a base is stolen. It was not until 1886 that the stolen base appeared as something to be tracked, but was only to "appear in the summary of the game". + +In 1887, the stolen base was given its own individual statistical column in the box score, and was defined for purposes of scoring: "...every base made after first base has been reached by a base runner, except for those made by reason of or with the aid of a battery error (wild pitch or passed ball), or by batting, balks or by being forced off. In short, shall include all bases made by a clean steal, or through a wild throw or muff of the ball by a fielder who is directly trying to put the base runner out while attempting to steal." The next year, it was clarified that any attempt to steal must be credited to the runner, and that fielders committing errors during this play must also be charged with an error. This rule also clarified that advancement of another base(s) beyond the one being stolen is not credited as a stolen base on the same play, and that an error is charged to the fielder who permitted the extra advancement. There was clarification that a runner is credited with a steal if the attempt began before a battery error. Finally, batters were credited with a stolen base if they were tagged out after over running the base. + +In 1892, a rule credited runners with stolen bases if a base runner advanced on a fly out, or if they advanced more than one base on any safe hit or attempted out, providing an attempt was made by the defense to put the runner out. The rule was rescinded in 1897. + +In 1898, stolen base scoring was narrowed to no longer include advancement in the event of a fielding error, or advancement caused by a hit batsman. + +1904 saw an attempt to reduce the already wordy slew of rules governing stolen bases, with the stolen base now credited when "the advances a base unaided by a base hit, a put out, (or) a fielding or batter error." + +1910 saw the first addressing of the double and triple steal attempts. Under the new rule, when any runner is thrown out, and the other(s) are successful, the successful runners will not be credited with a stolen base. + +Without using the term, 1920 saw the first rule that would be referred to today as defensive indifference, as stolen bases would not be credited, unless an effort was made to stop the runner by the defense. This is usually called if such is attempted in the ninth inning while that player's team is trailing, unless the runner represents the potential tying run. + +1931 saw a further narrowing of the criteria for awarding a stolen base. Power was given to the official scorer, in the event of a muff by the catcher in throwing, that in the judgment of the scorer the runner would have been out, to credit the catcher with an error, and not credit the runner with a stolen base. Further, any successful steal on a play resulting in a wild pitch, passed ball, or balk would no longer be credited as a steal, even if the runner had started to steal before the play. + +One of the largest rewrites to the rules in history came in 1950. The stolen base was specifically to be credited "to a runner whenever he advances one base unaided by a base hit, a putout, a forceout, a fielder's choice, a passed ball, a wild pitch, or a balk." + +There were noted exceptions, such as denying a stolen base to an otherwise successful steal as a part of a double or triple steal, if one other runner was thrown out in the process. A stolen base would be awarded to runners who successfully stole second base as a part of a double steal with a man on third, if the other runner failed to steal home, but instead was able to return safely to third base. Runners who are tagged out oversliding the base after an otherwise successful steal would not be credited with a stolen base. Indifference was also credited as an exception. Runners would now be credited with stolen bases if they had begun the act of stealing, and the resulting pitch was wild, or a passed ball. Finally, for 1950 only, runners would be credited with a stolen base if they were "well advanced" toward the base they were attempting to steal, and the pitcher is charged with a balk, with the further exception of a player attempting to steal, who would otherwise have been forced to advance on the balk by a runner behind them. This rule was removed in 1951. + +A clarification came in 1955 that awarded a stolen base to a runner even if he became involved in a rundown, provided he evaded the rundown and advanced to the base he intended to steal. + +The criteria for "caught stealing" were fine-tuned in 1979, with a runner being charged with being caught if he is put out while trying to steal, overslides a base (otherwise successfully stolen), or is picked off a base and tries to advance to the next base. It is explicitly not caught stealing to be put out after a wild pitch or passed ball. + +"Stealing first" + +While not recorded as a stolen base, the same dynamic between batter/runner and defense is on display in the case of an uncaught third strike. The batter/runner can avoid an out and become a baserunner by reaching first base ahead of the throw. This case is a strikeout that is not an out; the batter/runner's acquisition of first base is scored as a passed ball, a wild pitch, or an error. + +In baseball's earlier decades, a runner on second base could "steal" first base, perhaps with the intention of drawing a throw that might allow a runner on third to score (a tactic famously employed by Germany Schaefer). However, such a tactic was not recorded as a stolen base. MLB rules now forbid running clockwise on the basepaths to "confuse the defense or make a travesty of the game". Further, after the pitcher assumes the pitching position, runners cannot return to any previous base. + +In a game on August 16, 1987, Toronto Blue Jays center fielder Lloyd Moseby successfully stole second base on a throwing error by Chicago White Sox catcher Carlton Fisk that went well into center field. However, shortstop Ozzie Guillen faked as if the batter had hit a popfly, which would have required Moseby to return to first base to avoid getting doubled off. Moseby made it back to first base, but another throwing error sent the ball to the infield wall, giving Moseby another chance to steal second, which he did. This chaos led the announcer to say, "He doesn't know where the throw is; he's going back to first base! Is he going to steal first? He steals first! Now he's going to steal second again! I've never seen it before!" This bizarre play was officially scored as a baserunner advancing on a throwing error by the center fielder, ironically resulting in neither a stolen base awarded nor an error charged to the catcher. + +In a game on April 19, 2013, Milwaukee Brewers shortstop Jean Segura stole second base in the bottom of the eighth inning. After the batter up, Ryan Braun, walked, Segura broke early for third base and the pitcher, Shawn Camp of the Chicago Cubs, threw ahead of him. As Segura was chased back to second base, Braun advanced to second as well and was tagged out. Segura, thinking he was out, began to return to the home dugout behind first base, but first base coach Garth Iorg directed him to stand at first. Segura had not intentionally run the bases backwards as a deception or mockery, but no fielder tried to tag him out. Later in the inning, he attempted to steal second for the second time, but was thrown out by catcher Welington Castillo. + +The expression "You can't steal first base" is sometimes used in reference to a player who is fast but not very good at getting on base in the first place. Former Pittsburgh Pirates and Seattle Mariners manager Lloyd McClendon is jokingly referred to as having "stolen first" in a June 26, 2001 game as the manager of the Pirates: after being ejected for disputing a call at first base, he yanked the base out of the ground and left the field with it, delaying the game. Of the incident, McClendon said "I told him he wasn't using it, so I thought I'd take it." When a groundskeeper came out to replace the bag, the crowd booed him. + +The independent Atlantic League instituted a new rule for the second half of the 2019 season, allowing batters to become runners on any pitch not "caught in flight" by the catcher, as they can throughout baseball after most uncaught third strikes. On July 13, 2019, outfielder Tony Thomas of the Southern Maryland Blue Crabs became the first player to reach first base under this rule. The press described this as "stealing first base", though it is scored as described above. + +See also + + Lead off + Stolen base percentage + List of Major League Baseball career stolen bases leaders + List of Major League Baseball annual stolen base leaders + List of Major League Baseball stolen base records + Stolen run (cricket) + +References + +External links + +Baseball Almanac – List of MLB career leaders for stolen bases +Sports Illustrated – The 10 most significant steals of home in MLB history + +Baserunning statistics +Baseball terminology +In baseball, a player is credited with a plate appearance (denoted by PA) each time he completes a turn batting. Under Rule 5.04(c) of the Official Baseball Rules, a player completes a turn batting when he is put out or becomes a runner. This happens when he strikes out or is declared out before reaching first base; or when he reaches first base safely or is awarded first base (by a base on balls, hit by pitch, catcher's interference, or obstruction); or when he hits a fair ball which causes a preceding runner to be put out for the third out before he himself is put out or reaches first base safely (see also left on base, fielder's choice, force play). A very similar baseball statistic, at bats, counts a subset of plate appearances that end under certain circumstances. + +Use as batting record qualifier +At bats - rather than plate appearances - are used to calculate batting averages, slugging percentages. However, starting in 1957, at season's end a player must have accumulated 3.1 times the number of games scheduled for each team (502 plate appearances for a 162-game season) during a season to be ranked as a league-leader in certain statistical categories. For example, Player A gets 100 hits in 400 at bats over 510 plate appearances, which works out to a .250 batting average (equivalent to one hit in every four at-bats). Alternatively, Player B gets 110 hits in 400 at bats over 490 plate appearances during the same season, finishing with a .275 batting average. Player B, even though he had the same amount of at bats as Player A and even though his batting average is higher, will not be eligible for certain percentage-based season-ending rankings because he did not accumulate the required 502 plate appearances, while Player A did and therefore will be eligible. There is, however, an exception: + +Exception for batting titles +Rule 9.22(a) of the Official Baseball Rules make a single allowance to the minimum requirement of 502 plate appearances for the purposes of determining the batting, slugging or on-base percentage title. If a player: + + leads the league in one of the statistics; + does not have the required 502 plate appearances; and + would still lead the league in that statistic if as many at bats (without hits or reaching base) were added to his records as necessary to meet the requirement, + +he will win that title, but with his original statistic (before the extra at bats were added). + +In the example above, Player B is 12 plate appearances short of the required 502, but were he be charged with 12 additional unproductive at bats, he would go 110-for-412 for a batting average of .267. If no one else has a batting average (similarly modified if appropriate) higher than .267, player B will be awarded the batting title (with his original batting average of .275) despite the lack of 502 plate appearances. + +In a real-life example, in 2012, Melky Cabrera, then of the San Francisco Giants, finished the season with a league-high .346 batting average, but he had only 501 plate appearances, one short of the required 502. Per the rule, he would have won the batting title because after an extra at bat is added and his batting average recalculated, he still would have led the league in batting average. Cabrera's case, however, turned out differently. The reason Cabrera finished the season with only 501 at bats was because he was suspended in mid-August when he tested positive for illegal performance-enhancing drugs. Cabrera was still eligible for that extra plate appearance, but he requested that the extra plate appearance not be added to his total, and that he not be considered for the batting crown, because he admitted that his use of performance-enhancing drugs had given him an unfair advantage over other players. As a result, Cabrera's name is nowhere to be found on the list of 2012 National League batting leaders. + +Scoring +A batter is not credited with a plate appearance if, while batting, a preceding runner is put out on the basepaths for the third out in a way other than by the batter putting the ball into play (i.e., picked off, caught stealing). In this case, the same batter continues his turn batting in the next inning with no balls or strikes against him. + +A batter is not credited with a plate appearance if, while batting, the game ends as the winning run scores from third base on a balk, stolen base, wild pitch or passed ball. + +A batter may or may not be credited with a plate appearance (and possibly at bat) in the rare instance when he is replaced by a pinch hitter after having already started his turn at bat. Under Rule 9.15(b), the pinch hitter would receive the plate appearance (and potential of an at-bat) unless the original batter is replaced when having 2 strikes against him and the pinch hitter subsequently completes the strikeout, in which case the plate appearance and at-bat are charged to the first batter. + +Relation to at bat +Under Official Baseball Rule 9.02(a)(1), an at bat results from a completed plate appearance, unless the batter: + + hits a sacrifice bunt or sacrifice fly; or + is awarded first base on four called balls; or + is hit by a pitched ball; or + is awarded first base because of interference or obstruction. + +In common parlance, the term "at bat" is sometimes used to mean "plate appearance" (for example, "he fouled off the ball to keep the at bat alive"). The intent is usually clear from the context, although the term "official at bat" is sometimes used to explicitly refer to an at bat as distinguished from a plate appearance. However, terms such as turn at bat or time at bat are synonymous with plate appearance. + +"Time at bat" in the rulebook +Official Baseball Rule 5.06(c) provides that "[a] batter has legally completed his time at bat when he is put out or becomes a runner" (emphasis added). The "time at bat" defined in this rule is more commonly referred to as a plate appearance, and the playing rules (Rules 1 through 8) uses the phrase "time at bat" in this sense (e.g. Rule 5.04(a)(3), which states that "[t]he first batter in each inning after the first inning shall be the player whose name follows that of the last player who legally completed his time at bat in the preceding inning" (emphasis added)). In contrast, the scoring rules uses the phrase "time at bat" to refer to the statistic at bat, defined in Rule 9.02(a)(1), but sometimes uses the phrase "official time at bat" or refers back to Rule 9.02(a)(1) when mentioning the statistic. The phrase "plate appearance" is used in Rules 9.22 and 9.23 dealing with batting titles and hitting streaks, and in Rule 5.10(g) Comment in relation to the Three-Batter Minimum: "[t]o qualify as one of three consecutive batters, the batter must complete his plate appearance, which ends only when the batter is put out or becomes a runner." (emphasis added) The term is not elsewhere defined in the rulebook. + +In on-base percentage +Plate appearances are a primary component in calculating on-base percentage (OBP), an alternative measurement of a player's offensive performance, but are not the only one in determining its denominator. + +By rule, certain plate appearances, such as times reached base via either catcher's interference or fielder's obstruction or sacrifice bunts, are excluded from it, leaving the denominator determined instead as the sum of at-bats, walks, hit-by-pitches, and sacrifice flies. And the numerator represented by a batter's times on base (composed of the sum of hits, base on balls, and times hit by pitch). + +Other uses +Plate appearances are used by scorers for "proving" a box score.

DJ Scott La Rock was murdered on August 27, 1987, five months after the release of BDP's debut album, Criminal Minded. The name of the group, Boogie Down, derives from a nickname for the South Bronx section of New York City. The group pioneered the fusion of dancehall reggae and hip hop music and their debut LP Criminal Minded contained frank descriptions of life in the South Bronx during the late 1980s, thus setting the stage for what would eventually become gangsta rap. + +Members +BDP's membership changed throughout its existence, the only constant being KRS-One. The group was founded by KRS-One and DJ Scott La Rock, with producer Lee Smith, who was essential in the production of the songs on Criminal Minded, being added as a member shortly after. From those beginnings, BDP members and collaborators included Ced Gee of Ultramagnetic MC's, Lee Smith, Scott La Rock, D-Nice, Henry Wilkerson PoppyDa, Kenny Parker (KRS-One's younger brother), Just-Ice, ICU, McBoo, Ms. Melodie, Heather B., Scottie Morris, Tony Rahsan, Willie D., RoboCop, Harmony, DJ Red Alert, Jay Kramer, D-Square, Rebekah Foster, Scott Whitehill, Scott King, Chris Tait and Sidney Mills. BDP as a group essentially ended because KRS-One began recording and performing under his own name rather than the group name. Lee Smith, who has co-producer credit on the original 12" "South Bronx" single, was the first to be jettisoned by KRS-One and the future new label after Scott's death. + +In the liner notes on BDP's 1992 album Sex and Violence, KRS-One writes: "BDP in 1992 is KRS-One, Willie D, and Kenny Parker! BDP is not D-Nice, Jamal-Ski, Harmony, Ms. Melodie, and Scottie Morris. They are not down with BDP so stop frontin'." Steve "Flash" Juon of RapReviews.com claimed that this initiated the ultimate breakup of the group. + +Cultural influences and impact + +"The Bridge Wars" + +A conflict arose in the late 1980s concerning the origins of hip-hop, and BDP made conscious efforts in its early work to establish its interpretation of the issue. The origins of hip-hop to many, including BDP, are believed to be from the Bronx. A rival hip-hop collective, known as the Juice Crew's lyrics, were misunderstood to contain a claim in the song "The Bridge" that hip hop was directly a result of artists originating from Queensbridge. Boogie Down and KRS retorted angrily with songs such as "The Bridge is Over" and "South Bronx," which started one of the first notable hip hop wars as MC Shan, Marley Marl, Roxanne Shanté and Blaq Poet all released songs featuring verses personally attacking KRS and Scott La Rock. But the Bridge Wars were short-lived, and after Scott La Rock's death, KRS began to concentrate on socially conscious music. + +While Criminal Minded contained vivid descriptions of South Bronx street life, BDP changed after Scott's death. Lee Smith was dropped and KRS-One adopted the Teacha moniker and made a deliberate attempt at creating politically and socially conscious hip-hop. BDP was influential in provoking political and social consciousness in hip-hop, for example in "Stop The Violence" on 1988's By All Means Necessary. + +Jamaican inspirations +The Jamaican influence in Criminal Minded is well illustrated by the use of the "Mad Mad" or "Diseases" riddim started in 1981 with reggae star Yellowman's song "Zunguzung." BDP used this riff in the song "Remix for P is Free," and it was later resampled by artists such as Black Star and dead prez. As an album regarded by many as the start of the gangsta rap movement, Criminal Minded played an important role in reaffirming the social acceptance of having Jamaican roots. BDP referenced reggae in a way that helped to solidify Jamaica's place in modern hip-hop culture. + +Political and social activism +From its start, BDP affected the development of hip-hop and gave a sincere voice to the reality of life in the South Bronx, a section of New York City clouded with poverty and crime. With Criminal Minded, the group combined the sounds of LaRock's harsh, spare, reggae-influenced beats and KRS-One's long-winded rhyme style on underground classics such as "9mm Goes Bang" and "South Bronx," the album's gritty portrait of life on the streets (as well as the firearms that adorned its cover) influenced the gangsta rap movement that began in earnest two years later. + +BDP's influence in the creation and development of gangsta rap highlights the cultural significance and impact of the type of music BDP and other early hip-hop artists like it created. This subgenre of hip-hop is most closely associated with hard-core hip-hop and is widely misinterpreted as promoting violence and gang activity. This misinterpretation or stigma is closely related to Boogie Down Productions and the general purpose behind their underlying themes of violence. For instance, the cover art of Criminal Minded displays the two artists in the group brandishing drawn guns and displaying other firearms. This is not an encouragement of the violence described in BDP's music, but a portrayal of the violence in the South Bronx as a means of expression, escape, and even condemnation. This album art is not meant to advocate violence but to challenge the conception of a criminal, to assert that those who are really criminally minded are those who hold power. + +BDP's music became significantly more politically astute after Scott La Rock's death. KRS-One published four more albums under the title Boogie Down Productions, and each was increasingly innovative and expanded from the thuggish imagery of Criminal Minded, exploring themes like black-on-black crime and black radicalism, using a riff on the words of Malcolm X, "by any means necessary", which became the title of the second BDP album, and remains one of the most political hip-hop albums to date. It was in this album that KRS defined himself as the "teacha" or "teacher", symbolizing his emphasis on educating his audience members and fans about relevant social issues surrounding the African-American experience. + +During his time in association with Boogie Down Productions, KRS-One joined other rappers to create the Stop the Violence Movement, which addressed many of the issues brought up in BDP's music and is the most conscious effort displayed by KRS-One and BDP of political activism and engagement. The movement created the single "Self-Destruction" in 1989 through the collaboration of BDP (KRS-One, D-Nice & Ms. Melodie), Stetsasonic (Delite, Daddy-O, Wise, and Frukwan), Kool Moe Dee, MC Lyte, Doug E. Fresh, Just-Ice, Heavy D, Biz Markie, and Public Enemy (Chuck D & Flavor Flav), with the aim of spreading awareness about violence in African-American and hip-hop communities. All proceeds from this effort went to the National Urban League. + +Discography + +Studio albums +Criminal Minded (1987) +By All Means Necessary (1988) +Ghetto Music: The Blueprint of Hip Hop (1989) +Edutainment (1990) +Sex and Violence (1992) + +References + +Bibliography + "KRS-One."

Sometimes, special bit patterns are used for a sign or other indications (e.g. error or overflow). + +In byte-oriented systems (i.e. most modern computers), the term unpacked BCD usually implies a full byte for each digit (often including a sign), whereas packed BCD typically encodes two digits within a single byte by taking advantage of the fact that four bits are enough to represent the range 0 to 9. The precise four-bit encoding, however, may vary for technical reasons (e.g. Excess-3). + +The ten states representing a BCD digit are sometimes called tetrades (the nibble typically needed to hold them is also known as a tetrade) while the unused, don't care-states are named , pseudo-decimals or pseudo-decimal digits. + +BCD's main virtue, in comparison to binary positional systems, is its more accurate representation and rounding of decimal quantities, as well as its ease of conversion into conventional human-readable representations. Its principal drawbacks are a slight increase in the complexity of the circuits needed to implement basic arithmetic as well as slightly less dense storage. + +BCD was used in many early decimal computers, and is implemented in the instruction set of machines such as the IBM System/360 series and its descendants, Digital Equipment Corporation's VAX, the Burroughs B1700, and the Motorola 68000-series processors. BCD per se is not as widely used as in the past, and is unavailable or limited in newer instruction sets (e.g., ARM; x86 in long mode). However, decimal fixed-point and decimal floating-point formats are still important and continue to be used in financial, commercial, and industrial computing, where the subtle conversion and fractional rounding errors that are inherent in binary floating point formats cannot be tolerated. + +Background +BCD takes advantage of the fact that any one decimal numeral can be represented by a four-bit pattern. The most obvious way of encoding digits is Natural BCD (NBCD), where each decimal digit is represented by its corresponding four-bit binary value, as shown in the following table. This is also called "8421" encoding. + +This scheme can also be referred to as Simple Binary-Coded Decimal (SBCD) or BCD 8421, and is the most common encoding. Others include the so-called "4221" and "7421" encoding – named after the weighting used for the bits – and "Excess-3". For example, the BCD digit 6, in 8421 notation, is in 4221 (two encodings are possible), in 7421, while in Excess-3 it is (). + +The following table represents decimal digits from 0 to 9 in various BCD encoding systems. In the headers, the "8421" indicates the weight of each bit. In the fifth column ("BCD 84−2−1"), two of the weights are negative. Both ASCII and EBCDIC character codes for the digits, which are examples of zoned BCD, are also shown. + +As most computers deal with data in 8-bit bytes, it is possible to use one of the following methods to encode a BCD number: + Unpacked: Each decimal digit is encoded into one byte, with four bits representing the number and the remaining bits having no significance. + Packed: Two decimal digits are encoded into a single byte, with one digit in the least significant nibble (bits 0 through 3) and the other numeral in the most significant nibble (bits 4 through 7). + +As an example, encoding the decimal number 91 using unpacked BCD results in the following binary pattern of two bytes: + Decimal: 9 1 + Binary : 0000 1001 0000 0001 + +In packed BCD, the same number would fit into a single byte: + Decimal: 9 1 + Binary : 1001 0001 + +Hence the numerical range for one unpacked BCD byte is zero through nine inclusive, whereas the range for one packed BCD byte is zero through ninety-nine inclusive. + +To represent numbers larger than the range of a single byte any number of contiguous bytes may be used. For example, to represent the decimal number 12345 in packed BCD, using big-endian format, a program would encode as follows: + Decimal: 0 1 2 3 4 5 + Binary : 0000 0001 0010 0011 0100 0101 + +Here, the most significant nibble of the most significant byte has been encoded as zero, so the number is stored as 012345 (but formatting routines might replace or remove leading zeros). Packed BCD is more efficient in storage usage than unpacked BCD; encoding the same number (with the leading zero) in unpacked format would consume twice the storage. + +Shifting and masking operations are used to pack or unpack a packed BCD digit. Other bitwise operations are used to convert a numeral to its equivalent bit pattern or reverse the process. + +Packed BCD + +In packed BCD (or simply packed decimal), each nibble represent a decimal digit. Packed BCD has been in use since at least the 1960s and is implemented in all IBM mainframe hardware since then. Most implementations are big endian, i.e. with the more significant digit in the upper half of each byte, and with the leftmost byte (residing at the lowest memory address) containing the most significant digits of the packed decimal value. The lower nibble of the rightmost byte is usually used as the sign flag, although some unsigned representations lack a sign flag. As an example, a 4-byte value consists of 8 nibbles, wherein the upper 7 nibbles store the digits of a 7-digit decimal value, and the lowest nibble indicates the sign of the decimal integer value. + +Standard sign values are 1100 (hex C) for positive (+) and 1101 (D) for negative (−). This convention comes from the zone field for EBCDIC characters and the signed overpunch representation. Other allowed signs are 1010 (A) and 1110 (E) for positive and 1011 (B) for negative. IBM System/360 processors will use the 1010 (A) and 1011 (B) signs if the A bit is set in the PSW, for the ASCII-8 standard that never passed. Most implementations also provide unsigned BCD values with a sign nibble of 1111 (F). ILE RPG uses 1111 (F) for positive and 1101 (D) for negative. These match the EBCDIC zone for digits without a sign overpunch. In packed BCD, the number 127 is represented by 0001 0010 0111 1100 (127C) and −127 is represented by 0001 0010 0111 1101 (127D). Burroughs systems used 1101 (D) for negative, and any other value is considered a positive sign value (the processors will normalize a positive sign to 1100 (C)). + +No matter how many bytes wide a word is, there is always an even number of nibbles because each byte has two of them. Therefore, a word of n bytes can contain up to (2n)−1 decimal digits, which is always an odd number of digits. A decimal number with d digits requires (d+1) bytes of storage space. + +For example, a 4-byte (32-bit) word can hold seven decimal digits plus a sign and can represent values ranging from ±9,999,999. Thus the number −1,234,567 is 7 digits wide and is encoded as: + 0001 0010 0011 0100 0101 0110 0111 1101 + 1 2 3 4 5 6 7 − + +Like character strings, the first byte of the packed decimal that with the most significant two digits is usually stored in the lowest address in memory, independent of the endianness of the machine. + +In contrast, a 4-byte binary two's complement integer can represent values from −2,147,483,648 to +2,147,483,647. + +While packed BCD does not make optimal use of storage (using about 20% more memory than binary notation to store the same numbers), conversion to ASCII, EBCDIC, or the various encodings of Unicode is made trivial, as no arithmetic operations are required. The extra storage requirements are usually offset by the need for the accuracy and compatibility with calculator or hand calculation that fixed-point decimal arithmetic provides. Denser packings of BCD exist which avoid the storage penalty and also need no arithmetic operations for common conversions. + +Packed BCD is supported in the COBOL programming language as the "COMPUTATIONAL-3" (an IBM extension adopted by many other compiler vendors) or "PACKED-DECIMAL" (part of the 1985 COBOL standard) data type. It is supported in PL/I as "FIXED DECIMAL". Beside the IBM System/360 and later compatible mainframes, packed BCD is implemented in the native instruction set of the original VAX processors from Digital Equipment Corporation and some models of the SDS Sigma series mainframes, and is the native format for the Burroughs Corporation Medium Systems line of mainframes (descended from the 1950s Electrodata 200 series). + +Ten's complement representations for negative numbers offer an alternative approach to encoding the sign of packed (and other) BCD numbers. In this case, positive numbers always have a most significant digit between 0 and 4 (inclusive), while negative numbers are represented by the 10's complement of the corresponding positive number. As a result, this system allows for 32-bit packed BCD numbers to range from −50,000,000 to +49,999,999, and −1 is represented as 99999999. (As with two's complement binary numbers, the range is not symmetric about zero.) + +Fixed-point packed decimal +Fixed-point decimal numbers are supported by some programming languages (such as COBOL and PL/I). These languages allow the programmer to specify an implicit decimal point in front of one of the digits. For example, a packed decimal value encoded with the bytes 12 34 56 7C represents the fixed-point value +1,234.567 when the implied decimal point is located between the fourth and fifth digits: + 12 34 56 7C + 12 34.56 7+ + +The decimal point is not actually stored in memory, as the packed BCD storage format does not provide for it. Its location is simply known to the compiler, and the generated code acts accordingly for the various arithmetic operations. + +Higher-density encodings +If a decimal digit requires four bits, then three decimal digits require 12 bits. However, since 210 (1,024) is greater than 103 (1,000), if three decimal digits are encoded together, only 10 bits are needed. Two such encodings are Chen–Ho encoding and densely packed decimal (DPD). The latter has the advantage that subsets of the encoding encode two digits in the optimal seven bits and one digit in four bits, as in regular BCD. + +Zoned decimal +Some implementations, for example IBM mainframe systems, support zoned decimal numeric representations. Each decimal digit is stored in one byte, with the lower four bits encoding the digit in BCD form. The upper four bits, called the "zone" bits, are usually set to a fixed value so that the byte holds a character value corresponding to the digit. EBCDIC systems use a zone value of 1111 (hex F); this yields bytes in the range F0 to F9 (hex), which are the EBCDIC codes for the characters "0" through "9". Similarly, ASCII systems use a zone value of 0011 (hex 3), giving character codes 30 to 39 (hex). + +For signed zoned decimal values, the rightmost (least significant) zone nibble holds the sign digit, which is the same set of values that are used for signed packed decimal numbers (see above). Thus a zoned decimal value encoded as the hex bytes F1 F2 D3 represents the signed decimal value −123: + F1 F2 D3 + 1 2 −3 + +EBCDIC zoned decimal conversion table + +(*) Note: These characters vary depending on the local character code page setting. + +Fixed-point zoned decimal +Some languages (such as COBOL and PL/I) directly support fixed-point zoned decimal values, assigning an implicit decimal point at some location between the decimal digits of a number. For example, given a six-byte signed zoned decimal value with an implied decimal point to the right of the fourth digit, the hex bytes F1 F2 F7 F9 F5 C0 represent the value +1,279.50: + F1 F2 F7 F9 F5 C0 + 1 2 7 9. 5 +0 + +BCD in computers + +IBM + +IBM used the terms Binary-Coded Decimal Interchange Code (BCDIC, sometimes just called BCD), for 6-bit alphanumeric codes that represented numbers, upper-case letters and special characters. Some variation of BCDIC alphamerics is used in most early IBM computers, including the IBM 1620 (introduced in 1959), IBM 1400 series, and non-Decimal Architecture members of the IBM 700/7000 series. + +The IBM 1400 series are character-addressable machines, each location being six bits labeled B, A, 8, 4, 2 and 1, plus an odd parity check bit (C) and a word mark bit (M). For encoding digits 1 through 9, B and A are zero and the digit value represented by standard 4-bit BCD in bits 8 through 1. For most other characters bits B and A are derived simply from the "12", "11", and "0" "zone punches" in the punched card character code, and bits 8 through 1 from the 1 through 9 punches. A "12 zone" punch set both B and A, an "11 zone" set B, and a "0 zone" (a 0 punch combined with any others) set A. Thus the letter A, which is (12,1) in the punched card format, is encoded (B,A,1). The currency symbol $, (11,8,3) in the punched card, was encoded in memory as (B,8,2,1). This allows the circuitry to convert between the punched card format and the internal storage format to be very simple with only a few special cases. One important special case is digit 0, represented by a lone 0 punch in the card, and (8,2) in core memory. + +The memory of the IBM 1620 is organized into 6-bit addressable digits, the usual 8, 4, 2, 1 plus F, used as a flag bit and C, an odd parity check bit. BCD alphamerics are encoded using digit pairs, with the "zone" in the even-addressed digit and the "digit" in the odd-addressed digit, the "zone" being related to the 12, 11, and 0 "zone punches" as in the 1400 series. Input/Output translation hardware converted between the internal digit pairs and the external standard 6-bit BCD codes. + +In the Decimal Architecture IBM 7070, IBM 7072, and IBM 7074 alphamerics are encoded using digit pairs (using two-out-of-five code in the digits, not BCD) of the 10-digit word, with the "zone" in the left digit and the "digit" in the right digit. Input/Output translation hardware converted between the internal digit pairs and the external standard 6-bit BCD codes. + +With the introduction of System/360, IBM expanded 6-bit BCD alphamerics to 8-bit EBCDIC, allowing the addition of many more characters (e.g., lowercase letters). A variable length Packed BCD numeric data type is also implemented, providing machine instructions that perform arithmetic directly on packed decimal data. + +On the IBM 1130 and 1800, packed BCD is supported in software by IBM's Commercial Subroutine Package. + +Today, BCD data is still heavily used in IBM processors and databases, such as IBM Db2, mainframes, and Power6. In these products, the BCD is usually zoned BCD (as in EBCDIC or ASCII), Packed BCD (two decimal digits per byte), or "pure" BCD encoding (one decimal digit stored as BCD in the low four bits of each byte). All of these are used within hardware registers and processing units, and in software. To convert packed decimals in EBCDIC table unloads to readable numbers, you can use the OUTREC FIELDS mask of the JCL utility DFSORT. + +Other computers +The Digital Equipment Corporation VAX-11 series includes instructions that can perform arithmetic directly on packed BCD data and convert between packed BCD data and other integer representations. The VAX's packed BCD format is compatible with that on IBM System/360 and IBM's later compatible processors. The MicroVAX and later VAX implementations dropped this ability from the CPU but retained code compatibility with earlier machines by implementing the missing instructions in an operating system-supplied software library. This is invoked automatically via exception handling when the defunct instructions are encountered, so that programs using them can execute without modification on the newer machines. + +The Intel x86 architecture supports a unique 18-digit (ten-byte) BCD format that can be loaded into and stored from the floating point registers, from where computations can be performed. + +The Motorola 68000 series had BCD instructions. + +In more recent computers such capabilities are almost always implemented in software rather than the CPU's instruction set, but BCD numeric data are still extremely common in commercial and financial applications. There are tricks for implementing packed BCD and zoned decimal add–or–subtract operations using short but difficult to understand sequences of word-parallel logic and binary arithmetic operations. For example, the following code (written in C) computes an unsigned 8-digit packed BCD addition using 32-bit binary operations: +uint32_t BCDadd(uint32_t a, uint32_t b) +{ + uint32_t t1, t2; // unsigned 32-bit intermediate values + + t1 = a + 0x06666666; + t2 = t1 ^ b; // sum without carry propagation + t1 = t1 + b; // provisional sum + t2 = t1 ^ t2; // all the binary carry bits + t2 = ~t2 & 0x11111110; // just the BCD carry bits + t2 = (t2 >> 2) | (t2 >> 3); // correction + return t1 - t2; // corrected BCD sum +} + +BCD in electronics + +BCD is very common in electronic systems where a numeric value is to be displayed, especially in systems consisting solely of digital logic, and not containing a microprocessor. By employing BCD, the manipulation of numerical data for display can be greatly simplified by treating each digit as a separate single sub-circuit. This matches much more closely the physical reality of display hardware—a designer might choose to use a series of separate identical seven-segment displays to build a metering circuit, for example. If the numeric quantity were stored and manipulated as pure binary, interfacing with such a display would require complex circuitry. Therefore, in cases where the calculations are relatively simple, working throughout with BCD can lead to an overall simpler system than converting to and from binary. Most pocket calculators do all their calculations in BCD. + +The same argument applies when hardware of this type uses an embedded microcontroller or other small processor. Often, representing numbers internally in BCD format results in smaller code, since a conversion from or to binary representation can be expensive on such limited processors. For these applications, some small processors feature dedicated arithmetic modes, which assist when writing routines that manipulate BCD quantities. + +Operations with BCD + +Addition +It is possible to perform addition by first adding in binary, and then converting to BCD afterwards. Conversion of the simple sum of two digits can be done by adding 6 (that is, 16 − 10) when the five-bit result of adding a pair of digits has a value greater than 9. The reason for adding 6 is that there are 16 possible 4-bit BCD values (since 24 = 16), but only 10 values are valid (0000 through 1001). For example: + 1001 + 1000 = 10001 + 9 + 8 = 17 + +10001 is the binary, not decimal, representation of the desired result, but the most significant 1 (the "carry") cannot fit in a 4-bit binary number. In BCD as in decimal, there cannot exist a value greater than 9 (1001) per digit. To correct this, 6 (0110) is added to the total, and then the result is treated as two nibbles: + + 10001 + 0110 = 00010111 => 0001 0111 + 17 + 6 = 23 1 7 + +The two nibbles of the result, 0001 and 0111, correspond to the digits "1" and "7". This yields "17" in BCD, which is the correct result. + +This technique can be extended to adding multiple digits by adding in groups from right to left, propagating the second digit as a carry, always comparing the 5-bit result of each digit-pair sum to 9. Some CPUs provide a half-carry flag to facilitate BCD arithmetic adjustments following binary addition and subtraction operations. The Intel 8080, the Zilog Z80 and the CPUs of the x86 family provide the opcode DAA (Decimal Adjust Accumulator). + +Subtraction +Subtraction is done by adding the ten's complement of the subtrahend to the minuend. To represent the sign of a number in BCD, the number 0000 is used to represent a positive number, and 1001 is used to represent a negative number. The remaining 14 combinations are invalid signs. To illustrate signed BCD subtraction, consider the following problem: 357 − 432. + +In signed BCD, 357 is 0000 0011 0101 0111. The ten's complement of 432 can be obtained by taking the nine's complement of 432, and then adding one. So, 999 − 432 = 567, and 567 + 1 = 568. By preceding 568 in BCD by the negative sign code, the number −432 can be represented. So, −432 in signed BCD is 1001 0101 0110 1000. + +Now that both numbers are represented in signed BCD, they can be added together: + 0000 0011 0101 0111 + 0 3 5 7 + + 1001 0101 0110 1000 + 9 5 6 8 + = 1001 1000 1011 1111 + 9 8 11 15 + +Since BCD is a form of decimal representation, several of the digit sums above are invalid. In the event that an invalid entry (any BCD digit greater than 1001) exists, 6 is added to generate a carry bit and cause the sum to become a valid entry. So, adding 6 to the invalid entries results in the following: + 1001 1000 1011 1111 + 9 8 11 15 + + 0000 0000 0110 0110 + 0 0 6 6 + = 1001 1001 0010 0101 + 9 9 2 5 + +Thus the result of the subtraction is 1001 1001 0010 0101 (−925). To confirm the result, note that the first digit is 9, which means negative. This seems to be correct since 357 − 432 should result in a negative number. The remaining nibbles are BCD, so 1001 0010 0101 is 925. The ten's complement of 925 is 1000 − 925 = 75, so the calculated answer is −75. + +If there are a different number of nibbles being added together (such as 1053 − 2), the number with the fewer digits must first be prefixed with zeros before taking the ten's complement or subtracting. So, with 1053 − 2, 2 would have to first be represented as 0002 in BCD, and the ten's complement of 0002 would have to be calculated. + +Comparison with pure binary + +Advantages + Many non-integral values, such as decimal 0.2, have an infinite place-value representation in binary (.001100110011...) but have a finite place-value in binary-coded decimal (0.0010). Consequently, a system based on binary-coded decimal representations of decimal fractions avoids errors representing and calculating such values. This is useful in financial calculations. + Scaling by a power of 10 is simple. + Rounding at a decimal digit boundary is simpler. Addition and subtraction in decimal do not require rounding. + The alignment of two decimal numbers (for example 1.3 + 27.08) is a simple, exact shift. + Conversion to a character form or for display (e.g., to a text-based format such as XML, or to drive signals for a seven-segment display) is a simple per-digit mapping, and can be done in linear (O(n)) time. Conversion from pure binary involves relatively complex logic that spans digits, and for large numbers, no linear-time conversion algorithm is known (see ). + +Disadvantages + Some operations are more complex to implement. Adders require extra logic to cause them to wrap and generate a carry early. Also, 15 to 20 per cent more circuitry is needed for BCD add compared to pure binary. Multiplication requires the use of algorithms that are somewhat more complex than shift-mask-add (a binary multiplication, requiring binary shifts and adds or the equivalent, per-digit or group of digits is required). + Standard BCD requires four bits per digit, roughly 20 per cent more space than a binary encoding (the ratio of 4 bits to log210 bits is 1.204). When packed so that three digits are encoded in ten bits, the storage overhead is greatly reduced, at the expense of an encoding that is unaligned with the 8-bit byte boundaries common on existing hardware, resulting in slower implementations on these systems. + Practical existing implementations of BCD are typically slower than operations on binary representations, especially on embedded systems, due to limited processor support for native BCD operations. + +Representational variations +Various BCD implementations exist that employ other representations for numbers. Programmable calculators manufactured by Texas Instruments, Hewlett-Packard, and others typically employ a floating-point BCD format, typically with two or three digits for the (decimal) exponent. The extra bits of the sign digit may be used to indicate special numeric values, such as infinity, underflow/overflow, and error (a blinking display). + +Signed variations +Signed decimal values may be represented in several ways. The COBOL programming language, for example, supports five zoned decimal formats, with each one encoding the numeric sign in a different way: + +Telephony binary-coded decimal (TBCD) +3GPP developed TBCD, an expansion to BCD where the remaining (unused) bit combinations are used to add specific telephony characters, with digits similar to those found in telephone keypads original design. + +The mentioned 3GPP document defines TBCD-STRING with swapped nibbles in each byte. Bits, octets and digits indexed from 1, bits from the right, digits and octets from the left. +bits 8765 of octet n encoding digit 2n + +bits 4321 of octet n encoding digit 2(n – 1) + 1 + +Meaning number 1234, would become 21 43 in TBCD. + +Alternative encodings +If errors in representation and computation are more important than the speed of conversion to and from display, a scaled binary representation may be used, which stores a decimal number as a binary-encoded integer and a binary-encoded signed decimal exponent. For example, 0.2 can be represented as 2. + +This representation allows rapid multiplication and division, but may require shifting by a power of 10 during addition and subtraction to align the decimal points. It is appropriate for applications with a fixed number of decimal places that do not then require this adjustment—particularly financial applications where 2 or 4 digits after the decimal point are usually enough. Indeed, this is almost a form of fixed point arithmetic since the position of the radix point is implied. + +The Hertz and Chen–Ho encodings provide Boolean transformations for converting groups of three BCD-encoded digits to and from 10-bit values that can be efficiently encoded in hardware with only 2 or 3 gate delays. Densely packed decimal (DPD) is a similar scheme that is used for most of the significand, except the lead digit, for one of the two alternative decimal encodings specified in the IEEE 754-2008 floating-point standard. + +Application +The BIOS in many personal computers stores the date and time in BCD because the MC6818 real-time clock chip used in the original IBM PC AT motherboard provided the time encoded in BCD. This form is easily converted into ASCII for display. + +The Atari 8-bit family of computers used BCD to implement floating-point algorithms. The MOS 6502 processor has a BCD mode that affects the addition and subtraction instructions. The Psion Organiser 1 handheld computer's manufacturer-supplied software also entirely used BCD to implement floating point; later Psion models used binary exclusively. + +Early models of the PlayStation 3 store the date and time in BCD. This led to a worldwide outage of the console on 1 March 2010. The last two digits of the year stored as BCD were misinterpreted as 16 causing an error in the unit's date, rendering most functions inoperable. This has been referred to as the Year 2010 problem. + +Legal history +In the 1972 case Gottschalk v. Benson, the U.S. Supreme Court overturned a lower court's decision that had allowed a patent for converting BCD-encoded numbers to binary on a computer. The decision noted that a patent "would wholly pre-empt the mathematical formula and in practical effect would be a patent on the algorithm itself". This was a landmark judgement that determining the patentability of software and algorithms. + +See also + Bi-quinary coded decimal + Binary-coded ternary (BCT) + Binary integer decimal (BID) + Bitmask + Chen–Ho encoding + Decimal computer + Densely packed decimal (DPD) + Double dabble, an algorithm for converting binary numbers to BCD + Year 2000 problem + +Notes + +References + +Further reading + + + and (NB.

He was the eldest son of Ashina Tuwu (吐務 / 吐务). He was the chieftain of the Turks under the sovereignty of Rouran Khaganate. He is also mentioned as Tumen (, , commander of ten thousand) of the Rouran Khaganate. + +Early life and reign +According to History of Northern Dynasties and Zizhi Tongjian, in 545 Tumen's tribe started to rise and frequently invaded the western frontier of Wei. The chancellor of Western Wei, Yuwen Tai, sent An Nuopanto (安諾盤陀, Nanai-Banda, a Sogdian from Bukhara,) as an emissary to the Göktürk chieftain Tumen, in an attempt to establish a commercial relationship. In 546, Tumen paid tribute to the Western Wei state. In that same year, Tumen put down a revolt of the Tiele tribes against the Rouran Khaganate, their overlords. Following this, Tumen felt entitled to request of the Rouran a princess as his wife. The Rouran khagan, Anagui, sent a message refusing this request and adding: "You are my blacksmith slave. How dare you utter these words?" Bumin got angry, killed Anagui's emissary, and severed relations with the Rouran Khaganate. Anagui's "blacksmith" (鍛奴 / 锻奴, Pinyin: duàn nú, Wade–Giles: tuan-nu) insult was recorded in Chinese chronicles. Some sources state that members of the Tujue did serve blacksmiths for the Rouran elite, and that "blacksmith slavery" may refer to a kind of vassalage that prevailed in Rouran society. Nevertheless, after this incident Bumin emerged as the leader of the revolt against Rouran. + +In 551, Bumin requested a Western Wei princess in marriage. Yuwen Tai permitted it and sent Princess Changle(長樂公主) of Western Wei to Bumin. In the same year when Emperor Wen of Western Wei died, Bumin sent mission and gave two hundred horses. + +The beginning of formal diplomatic relations with China propped up Bumin's authority among the Turks. He eventually united the local Turkic tribes and threw off the yoke of the Rouran domination. In 552 Bumin's army defeated Anagui's forces at the north of Huaihuang and then Anagui committed suicide. With their defeat Bumin proclaimed himself "Illig Qaghan" and made his wife qaghatun. "Illig" means Ilkhan (i.e. ruler of people) in Old Turkic. According to the Bilge Qaghan's memorial complex and the Kul Tigin's memorial complex, Bumin and Istemi ruled people by Turkic laws and they developed them. + +Death and family +Bumin died within several months after proclaiming himself Illig Qaghan.

His accomplishments were described in the Orkhon inscriptions. + +Names +As was the custom, his personal name and the name after assuming the title Qaghan were different. His personal name was recorded in Chinese characters as (). His name after assuming the title was Bilgä Qaγan. (, ). + +Early years +He was born in 683, in the early years of the khaganate. He campaigned alongside his father from early childhood. He was created as Tardush shad and given command over the western wing of the empire in 697 by Qapaghan. He managed to annihilate Wei Yuanzhong's army in 701 with his brother. He also reconquered Basmyl tribes in 703. He also subdued Yenisei Kyrgyz forces in 709, after their disobedience had to reconquer and kill their Qaghan in 710. He killed Türgesh khagan Suoge at Battle of Bolchu. + +In later years of Qapaghan, he had to fight four battles in a year starting from 714, resubduing tribes and nearly was killed in an ambush from Uyghur forces in 716. + +Reign + +In 716, Qapaghan Qaghan, the second Qaghan, was killed in his campaign against the Toquz Oghuz alliance and his severed head was sent to Chang'an. Although his son Inel Khagan succeeded him, Bilgä's brother Kul Tigin and Tonyukuk carried out a coup d'état against Inel Qaghan. They killed him and made him Bilgä Qaghan. His name literally means "wise king". + +He appointed his brother Kul Tigin to be Left Wise Prince, which made second most powerful person in realm. He re-subdued Huige in 716. He also appointed his father-in-law Tonyukuk to be Master Strategist. + +New reforms and stabilization of the regime, caused tribes that fled Tujue to come back. Tang chancellor Wang Jun, believing that the Göktürks who surrendered would try to flee back to the Göktürk state, suggested that they be forcibly moved into the heart of the empire to prevent them from doing so. Before Wang's suggestion could be acted upon, however, there was an uprising by the Göktürks who surrendered, under the leadership of Xiedie Sitai (𨁂跌思泰) and Axilan (阿悉爛). Xue and Wang tried to intercept them and dealt them defeats, but they were able to flee back to the Göktürk state anyway. This defeat led to Xue Ne's retirement. + +Religious policy +At some point in his life, he thought about converting to Buddhism and settling in cities. However, Tonyukuk discouraged him from this, citing the Turks' few numbers and vulnerability to Chinese attacks. While the Turks' power rested on their mobility, conversion to Buddhism would bring pacifism among the population. Therefore, sticking to Tengrism was necessary for survival. + +Later reign + +In 720, Wang believed that the Pugu (僕固) and Xiedie tribes of the region were planning to defect to Eastern Tujue and attack with Eastern Tujue troops. He thus held a feast and invited the chieftains, and, at the feast, massacred them. He then attacked the Pugu and Xiedie tribes in the area, nearly wiping them out. He then proposed a plan to attack Qaghan along with the Baximi, Xi, and Khitan. Emperor Xuanzong also recruited Qapaghan Khagan's sons Bilgä Tigin and Mo Tigin, Yenisei Kyrgyz Qaghan Kutluk Bilgä Qaghan and Huoba Guiren to fight against Tujue. Tonyukuk cunningly launched first attack on Baximi in 721 autumn, completely crushing them. Meanwhile, Bilgä raided Gansu, taking much of the livestock. Later that year Khitans, next year Xi were also crushed. + +In 726, his father-in-law and chancellor Tonyukuk died. + +In 727, he sent Buyruk Chor () as en emissary to Xuanzong to send 30 horses as gift. He also alarmed him of Me Agtsom's proposal of anti-Tang alliance. This alarm proved to be true when Tibetan general We Tadra Khonglo invaded Tang China in 727, sacked Guazhou (瓜州, in modern Gansu), Changle (常樂, in south of modern Guazhou County), Changmenjun (長門軍, in north of modern Yumen) and Anxi (安西, modern Lintan). + +On 27 February 731, Kul Tigin died, for which Qaghan mourned and ordered a great funeral ceremony. + +In 733, he defeated rebellious Khitan tribes. + +Death +Just after sending an emissary to Xuanzong to gain heqin alliance, he was poisoned by Buyruk Chor.
