Can you name the first woman to ever hold the position of Prime Minister?

Margaret Thatcher, often referred to as the "Iron Lady," holds a significant place in British political history as the first female Prime Minister. Her tenure, lasting from 1979 to 1990, was marked by significant economic and social reforms. Before Thatcher, British politics was dominated by male figures, making her rise to power a groundbreaking achievement. She led the Conservative Party to three consecutive general election victories, implementing policies such as privatization of state-owned industries and reforms to trade unions. While figures like Florence Nightingale are celebrated for their contributions to nursing and Elizabeth Brown and Mary Peters for their achievements in other fields, none of them held the office of Prime Minister. Thatcher's impact on British society and her status as the first female Prime Minister make her the only correct answer.
