Sir Oswald Ernald Mosley, 6th Baronet (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, having become disillusioned with mainstream politics, he became the leader of the British Union of Fascists (BUF). Mosley was never knighted, but inherited the title 'Sir' by virtue of his baronetcy; he was the sixth baronet of a title that had been in his family for more than a century when he succeeded to the title upon his father's death on 21 September 1928.
