Attlee was born into an upper middle class family, the son of a wealthy London solicitor. After attending Haileybury College and the University of Oxford, he practised as a barrister. The volunteer work he carried out in London's East End exposed him to poverty, and his political views shifted leftwards thereafter. He joined the Independent Labour Party, gave up his legal career, and began lecturing at the London School of Economics; with his work briefly interrupted by service as an officer in the First World War. In 1919, he became mayor of Stepney and in 1922 was elected to Parliament as the Member for Limehouse. Attlee served in the first Labour minority government led by Ramsay MacDonald in 1924, and then joined the Cabinet during MacDonald's second minority (1929–1931). After retaining his seat in Labour's landslide defeat of 1931, he became the party's Deputy Leader. Elected Leader of the Labour Party in 1935, and at first advocating pacificism and opposing re-armament, he became a critic of Neville Chamberlain's policy of appeasement in the lead-up to the Second World War. Attlee took Labour into the wartime coalition government in 1940 and served under Winston Churchill, initially as Lord Privy Seal and then as Deputy Prime Minister from 1942.
