Sir Oswald Ernald Mosley, 6th Baronet was a British aristocrat and politician who rose to fame during the 1920s and 1930s when, having become disillusioned with mainstream politics, he turned to fascism. He was a member of parliament and later founded and led the British Union of Fascists (BUF).

The British Union of Fascists (BUF) was a British fascist political party formed in 1932 by Oswald Mosley. Mosley changed its name to the British Union of Fascists and National Socialists in 1936 and, in 1937, to the British Union. In 1939, following the start of the Second World War, the party was proscribed by the British government and in 1940 it was disbanded.
