In which season does the character of Margaret Thatcher appear?

Margaret Thatcher appears in season 4 of The Crown. Gillian Anderson portrays Thatcher, who becomes Britain’s first female prime minister and serves alongside Queen Elizabeth II during the season’s 1979–1990 period.

Thatcher entered Downing Street in May 1979 after the Conservative Party won the general election. Her premiership lasted more than eleven years, making her the longest-serving British prime minister of the 20th century. Season 4 follows major events from her tenure, including the Falklands War, the miners’ conflict, and her eventual resignation in 1990.

Viewers sometimes confuse the season with the character’s historical dates: Thatcher was not part of the earlier seasons, which focus on the 1950s and 1960s. The Crown also dramatizes private conversations between Thatcher and the Queen, so scenes involving their personal relationship should not be treated as literal transcripts of recorded history.
