The Union Movement was a fascist political party in the United Kingdom that was active from 1948 to 1973, founded by Oswald Mosley. Following the release of interned fascists at the end of World War II, they re-founded the British Union of Fascists under Mosley, its original leader. An increase in immigration led to the growth of the movement, which called for assisted repatriation and spread myths about the sexual deviance of blacks. The party dropped its commitment to British nationalism in favor of European unity, but it declined in the late 1960s and early 1970s. In 1973, the party was renamed to the "Action Party", which lasted less than a decade before being dissolved.
