Born in Grantham in Lincolnshire, England, Margaret Hilda Roberts attended Somerville College of the University of Oxford. She was selected for Finchley in 1958 and took her seat in the House of Commons the following year. Upon the election of Edward Heath in 1970, Thatcher was appointed Secretary of State for Education and Science. In 1974, she backed Sir Keith Joseph for the Conservative party leader, but after falling short he dropped out of the race; Thatcher entered herself and became leader of the Conservative party in 1975. Among other things, she defiantly opposed the Soviet Union, and her tough-talking rhetoric gained her the nickname the "Iron Lady." As the Conservative party maintained leads in most polls, Thatcher went on to become Britain's Prime Minister in the 1979 General Election.
