Margaret Thatcher, leader of the Conservative Party, becomes Britain’s first female prime minister on May 4, 1979. The Oxford-educated chemist and lawyer took office the day after the Conservatives won a 44-seat majority in general parliamentary elections.
In March 1979, Callaghan was defeated by a vote of no confidence, and on May 3 a general election gave Thatcher’s Conservatives a majority in Parliament. The next day, Prime Minister Thatcher immediately set about dismantling socialism in Britain. She privatized numerous industries, cut back government expenditures, and gradually reduced the rights of trade unions. In 1983, despite the worst unemployment figures for half a decade, Thatcher was reelected to a second term, thanks largely to the decisive British victory in the 1982 Falklands War with Argentina.
