Robert Anthony Eden, 1st Earl of Avon (12 June 1897 – 14 January 1977), was a British politician and military officer who served as Prime Minister of the United Kingdom and Leader of the Conservative Party from 1955 until his resignation in 1957. Achieving rapid promotion as a young Conservative member of Parliament, he became foreign secretary aged 38, before resigning in protest at Neville Chamberlain's appeasement policy towards Benito Mussolini's Fascist regime in Italy. He returned to that position for most of the Second World War, and held it for a third time in the early 1950s. Having been deputy to Winston Churchill for almost 15 years, Eden succeeded him as the leader of the Conservative Party and prime minister in 1955, and a month later won a general election.
