Margaret Thatcher
Margaret Thatcher was a British politician who served as Prime Minister from 1979 to 1990, becoming the first woman to hold the office and one of the most influential and polarizing leaders in modern British history.
Thatcher rose through the Conservative Party to become its leader in 1975 and won the 1979 general election amid widespread economic difficulty in Britain.
Her government pursued sweeping free-market economic reforms, including privatizing state-owned industries and curbing the power of trade unions, policies that earned her the nickname 'the Iron Lady' for her uncompromising leadership style.
Thatcher led Britain through the Falklands War in 1982 and remained in office for over 11 years, the longest continuous tenure of any British prime minister in the 20th century, before resigning in 1990 amid internal party pressure.
