James Harold Wilson, Baron Wilson of Rievaulx, (11 March 1916 – 24 May 1995) was a British statesman and Labour politician who served as Prime Minister of the United Kingdom twice, from October 1964 to June 1970 and again from March 1974 to April 1976. He was the Leader of the Labour Party from 1963 to 1976, and was a Member of Parliament (MP) from 1945 to 1983. Wilson is the only Labour leader to have formed administrations following four general elections.
Born in Huddersfield, Yorkshire, to a politically active middle-class family, Wilson won a scholarship to attend Royds Hall Grammar School and went on to study philosophy, politics and economics at Jesus College, Oxford. He was later an economic history lecturer at New College, Oxford, and a research fellow at University College, Oxford. Elected to Parliament in 1945 for the seat of Ormskirk in Lancashire, Wilson was immediately appointed to the Attlee government as a Parliamentary Secretary; he became Secretary for Overseas Trade in 1947, and was elevated to the Cabinet shortly thereafter as President of the Board of Trade. In 1950, he moved to represent the nearby seat of Huyton. Following Labour's defeat at the 1955 election, Wilson joined the Shadow Cabinet as Shadow Chancellor, and was moved to the role of Shadow Foreign Secretary in 1961. When Labour Leader Hugh Gaitskell died suddenly in January 1963, Wilson won the subsequent leadership election to replace him, becoming Leader of the Opposition.
Wilson led Labour to a narrow victory at the 1964 election. His first period as prime minister saw a period of low unemployment and relative economic prosperity, although this would later become hindered by significant problems with Britain's external balance of payments. The Wilson government oversaw significant societal changes in the United Kingdom, abolishing both capital punishment and theatre censorship, partially decriminalising male homosexuality in England and Wales, relaxing the divorce laws, limiting immigration, and liberalising birth control and abortion law.
