The Crusade is the sixth serial of the second season in the British science fiction television series Doctor Who. Written by David Whitaker and directed by Douglas Camfield, the serial was broadcast on BBC1 in four weekly parts from 27 March to 17 April 1965. In this serial, the First Doctor (William Hartnell) and his travelling companions Ian Chesterton (William Russell), Barbara Wright (Jacqueline Hill), and Vicki (Maureen O'Brien) arrive in 12th century Palestine during the Third Crusade, and find themselves entangled in the conflict between King Richard the Lionheart (Julian Glover) and Saladin (Bernard Kay). They also meet King Richard's sister Lady Joanna (Jean Marsh) and Saladin's brother Saphadin (Roger Avon). Whitaker wrote the serial after departing his role as the show's story editor in 1964. He was fascinated by the Third Crusade, and found the historical figures effective material for a character drama, particularly the relationship between King Richard and his sister. Story editor Dennis Spooner was impressed by the maturity and near-Shakespearean nature of Whitaker's scripts, and Camfield considered them the best he directed for the show. Viewership fell from the previous serial and dropped throughout the four weeks, but was considered acceptable. The Crusade received positive reviews, with praise directed at the writing, performances, and set design. Two of the four episodes remain missing after the BBC wiped them from archives. The story received several print adaptations and home media releases, with the missing episodes reconstructed using off-air recordings.

Barbara and William des Preaux (John Flint) are presented to Saladin's brother Saphadin (Roger Avon) by El Akir (Walter Randall), who mistakenly believes them to be King Richard and his sister Lady Joanna. When des Preaux reveals their true identities, El Akir is furious; before he can act, Saladin (Bernard Kay) emerges and is intrigued by Barbara. He invites her to entertain him with her stories at supper. Ian, anxious to rescue Barbara, asks for the King's
