full_context: Document 1: List of members of the British Free Corps: This is a list of members of the British Free Corps. It is based on the list printed in Appendix 5 of Adrian Weale. "Renegades: Hitler's Englishmen". London: Weidenfeld & Nicolson, 1994. ISBN  . The Corps (German: "Britisches Freikorps" ) was a unit of the Waffen SS during World War II consisting of British and Dominion prisoners of war who had been recruited by the Nazis. The Corps used the SS rank structure. The column 'MI5 no.' refers to the number allocated to the member in question in MI5's Report on the British Free Corps dated 27 March 1945, which is printed in Appendix 1 of 'Renegades'. Starting in February 1944, BFC members were ordered to adopt aliases for official purposes, although several declined to do so.
Document 2: Alan Hancock: Alan Vivien Hancock (14 August 1914-July, 1989) was one of the early leaders of the Racial Preservation Society (RPS). He was formerly a member of the British Union of Fascists (BUF) which was formed in 1932 by ex-Labour government minister Sir Oswald Mosley and was a union of several small, extreme nationalist parties. Hancock formed part of a three-man leadership team in the RPS who came from the BUF, alongside Ted Budden and Jimmy Doyle.
Document 3: British Movement: The British Movement (BM), later called the British National Socialist Movement (BNSM), is a British Neo-Nazi organisation founded by Colin Jordan in 1968. It grew out of the National Socialist Movement (NSM), which was founded in 1962. Frequently on the margins of the British far-right, the BM has had a long and chequered history for its association with violence and extremism. It was founded as a political party but manifested itself more as a pressure and activist group. It has had spells of dormancy.
Document 4: Nationalist Movement: The Nationalist Movement is a Mississippi-founded, white nationalist organization with headquarters in Georgia that advocates what it calls a "pro-majority" position. It has been called white supremacist by the Associated Press and Anti-Defamation League, among others. Richard Barrett was succeeded by unanimous vote as leader by Thomas Reiter after Barrett's murder. Its Secretary originally was Barry Hackney, and the position of Secretary was discontinued by Thomas Reiter. Thomas Reiter saved most Nationalist Movement assets and intellectual property after Barrett's murder. The symbol of the movement is the Crosstar. In 2012 with the endorsement of Thomas Reiter, Travis Golie was sworn in as the Leader of The Nationalist Movement. Like Reiter, Golie was an original Barrett-era Nationalist Movement member. Golie returned The Nationalist Movement headquarters to the South where it originated.
Document 5: The Blackshirt: The Blackshirt was the official newspaper of Oswald Mosley's British Union of Fascists (BUF). The paper first appeared in 1933. From June 1939 it became the "British Union News". It ceased the same year. The paper also incorporated the short-lived "The Fascist Week" (1933-34).
Document 6: Max Mosley: Max Rufus Mosley (born 13 April 1940) is the former president of the Fédération Internationale de l'Automobile (FIA), a non-profit association that represents the interests of motoring organisations and car users worldwide. The FIA is also the governing body for Formula One and other international motorsports.
Document 7: Union Movement: The Union Movement was a far-right political party founded in Britain by Oswald Mosley. Where Mosley had been associated with a peculiarly British form of fascism, the Union Movement attempted to redefine the concept by stressing the importance of developing a European nationalism rather than narrower country-based nationalisms. The UM has therefore been characterized as an attempt by Mosley to start again in his political life by embracing more democratic and international policies, than those with which he had been associated.
Document 8: The European (1953 magazine): The European was a privately circulated far-right cultural and political magazine that was published between 1953 and 1959. During this tenure, it was edited by fascist supporter and politician Diana Mosley. The magazine was published by 'Euphorion Books', a publishing company formed by Mosley and her husband, Sir Oswald Mosley, founder of the British Union of Fascists.
Document 9: John Warburton (fascist): John Warburton (30 April 1919 – 26 August 2004) was an English fascist and press photographer. He was an assistant district leader for the Clapham branch of Oswald Mosley's British Union of Fascists (BUF) before the Second World War, and afterwards was a key member of the Union Movement, the founder editor of "Comrade", and the senior Council member of Friends of Oswald Mosley.
Document 10: Ancoats Hall: Ancoats Hall in Ancoats, Manchester, England, was a post-medieval country house built in 1609 by Oswald Mosley, a member of the family who were Lords of the Manor of Manchester. The old timber-framed hall, built in the early 17th century, was described by John Aiken in his 1795 book "Description of the country from 30 to 40 miles around Manchester". The old hall was demolished in the 1820s and replaced by a brick building in the early neo-Gothic style. The new hall, at the eastern end of Great Ancoats Street between Every Street and Palmerston Street, was demolished in the 1960s.
Document 11: British Union of Fascists: The British Union of Fascists, or BUF, was a fascist political party in the United Kingdom formed in 1932 by Oswald Mosley. It changed its name to the "British Union of Fascists and National Socialists" in 1936 and, in 1937, to "British Union". It was finally disbanded in 1940 after it was proscribed by the British government, following the start of the Second World War.
Document 12: Oswald Mosley: Sir Oswald Ernald Mosley, 6th Baronet of Ancoats ( ; 16 November 1896 – 3 December 1980) was a British politician who rose to fame in the 1920s as a Member of Parliament and later in the 1930s became leader of the British Union of Fascists (BUF).
Document 13: Friends of Oswald Mosley: The Friends of Oswald Mosley (FOM) is the last vestige of Oswald Mosley's British Union of Fascists (BUF) and its successors the Union Movement and the Action party. Their motto is "The spirit lives ... the rest will follow". The group is not politically active but has described itself as "pro-Islam, pro-EU, against US global supremacy, anti-capitalist, anti-state socialism, [and] pro-syndicalism".
Document 14: Flash and Circle: The Flash and Circle is the second symbol used by the British Union of Fascists (BUF) and its best known symbol. (The BUF had briefly used the fasces of Mussolini's fascists.) It was chosen to represent "action within unity". Oswald Mosley's post-war group the Union Movement and his National Party of Europe initiative also used this symbol.
Document 15: Richard Edensor Heathcote: Richard Edensor Heathcote (1780–1850) was a British industrialist. Born the son of Sir John Edensor Heathcote of Longton Hall. He was elected the Member of Parliament (MP) for Coventry in 1826 and rebuilt (in the Elizabethan style) Apedale Hall, near Newcastle, in Staffordshire, at about the same time. He died in Genova, Italy, in 1850. A descendant was Oswald Mosley, the founder of the British Union of Fascists who lived for a time at Apedale Hall.
