Harold Wilson (James Harold Wilson, Baron Wilson of Rievaulx), 1916–95, British statesman. A graduate of Oxford, he became an economics lecturer there (1937) and a fellow of University College (1938). Wilson entered Parliament (1945) as a Labour member, and as president of the Board of Trade (1947–51) he ended many of the wartime controls on industry. In 1951 he resigned with Aneurin Bevan, opposing the introduction of changes within the National Health Service. He thus became a spokesman for the left-wing of the Labour party, later opposing party leader Hugh Gaitskell's stand against unilateral nuclear disarmament.
After Gaitskell's death (1963), Wilson won the leadership of the party and became prime minister in 1964. At first his government had only a four-seat majority in Parliament, but it was reelected with a large majority in 1966. The Labour government under Wilson sought to offset Britain's diminishing role outside Europe by increasing its role in Europe, and in 1967 it reapplied for membership in the European Community (EC). Wilson also tried unsuccessfully to reach a settlement with the white supremacist regime in Rhodesia (now Zimbabwe), which unilaterally declared itself independent of Britain in 1965. Domestically, Wilson imposed strict controls on wages and prices, raised taxes, and devalued (1967) the pound to end the growing economic crisis. By the spring of 1970 the economy seemed to be recovering, and Wilson scheduled a June election, which resulted in an unexpected defeat for the Labour party.
In opposition, Wilson led his party to reverse its stand on entry into the EC, but a significant minority voted with the Conservative government in favor of entry. Another divisive issue arose with the party's espousal (1973) of wide-scale nationalization. Nonetheless, in the general election of Feb., 1974, held at a time of severe economic crisis, Labour was returned to power, and Wilson again became prime minister.
Despite the fact that he headed a minority government (and was therefore very vulnerable to defeat in Parliament), Wilson announced his intention of implementing the controversial policies of renegotiation of the terms of Britain's membership in the EC and nationalization. His government faced continuing economic difficulties as well as a deterioration of the situation in Northern Ireland (which required the reimposition of direct British rule). It was also obliged to mediate between Greece and Turkey in the tense crisis created by the overthrow of Archbishop Makarios III in Cyprus and the subsequent Turkish invasion of that island in July, 1974. Wilson called another election in Oct., 1974, and secured a narrow majority in Parliament. In 1975 he called and won an unprecedented referendum on Britain's membership in the EC, largely silencing left-wing Labour critics who favored withdrawal. Wilson unexpectedly resigned in 1976 and was knighted later the same year. The longest serving Labour prime minister, he retained his seat in Commons until he was created a life peer in 1983.
