Edmund Crouchback

Edmund Crouchback, Earl of Lancaster, Leicester, and Derby was a member of the House of Plantagenet. He was the second surviving son of King Henry III of England and Eleanor of Provence. In his childhood he had a claim on the Kingdom of Sicily; however, he never ruled there. He was granted all the lands of Simon de Montfort in 1265, and from 1267 he was titled Earl of Leicester. In that year he also began to rule Lancashire, but he did not take the title Earl of Lancaster until 1276. Between 1276 and 1284 he governed the counties of Champagne and Brie with his second wife, Blanche of Artois, in the name of her daughter Joan, and he was described in the English patent rolls as earl of Lancaster and Champagne. His nickname, "Crouchback", may be a corruption of 'crossback' and refer to his participation in the Ninth Crusade.
