Sir Oswald Ernald Mosley, 6th Baronet, was a British aristocrat and politician who rose to fame during the 1920s and 1930s when, disillusioned with mainstream politics, he turned to fascism. He was Member of Parliament (MP) for Harrow from 1918 to 1924 and for Smethwick from 1926 to 1931. He founded the British Union of Fascists (BUF) in 1932 and led it until its forced disbandment in 1940.
