The season 4 episode about the Falklands War is titled “War.” It is the tenth and final episode of The Crown’s fourth season, released on November 15, 2020.
The episode places Margaret Thatcher’s political crisis alongside the worsening breakdown of Charles and Diana’s marriage. Thatcher’s government had led Britain through the 1982 conflict with Argentina after Argentine forces invaded the Falkland Islands, a British overseas territory in the South Atlantic.
The real conflict lasted 74 days and ended with Argentina’s surrender in June 1982. The Crown compresses and dramatizes events, so “War” is not a documentary account of the campaign. “The Iron Lady” is the season’s fourth episode and focuses more directly on Thatcher’s arrival in power; “Falklands” is not the title of a season 4 episode.
