Ivanhoe is a British television adventure series first shown on ITV in 1958-59. The show stars Roger Moore in his first starring role, as Sir Wilfred of Ivanhoe, in a series of adventures aimed at a children's audience. The characters were drawn loosely from Sir Walter Scott's 1819 novel Ivanhoe.
The series is set in England during the 12th century reign of King Richard the Lionheart, who had gone to fight in the Crusades and failed to return. In his absence, power had been taken by his younger brother, the ambitious and wicked Prince John, who sought to strip the people of their rights and land. The dashing and heroic knight Ivanhoe, with his father-and-son companions Gurth and Bart whom he had freed from servitude (from the evil Sir Maurice), attempted to right wrongs, secure justice, help those in need, and thwart John and his allies.
