Starting out as the British Union of Fascists in 1932, and changing it's name to the British Union in 1937, this British group was disbanded in 1940.
Initially finding wide support in Britain, with backing from notables such as Lord Rothermere, the British Union was made a target of the British government. This included the Public Order Act 1936 which banned political uniforms, such as the black shirts worn by the British Union leading their nickname the blackshirts.
After the outbreak of WWII the British press attacked the group for being sympathetic towards Germany and the group was fully outlawed by the British government in 1940 when it's leader, Sir Oswald Mosely, was put in a British prison. Mosely had favored negotiating a peace treaty, and had ties with Italy. He and his wife were both interned without trial in Holloway Prison until 1943 when they were put under House Arrest for the remainder of the war.
