Edmund Crouchback
Edmund Crouchback , a member of the House of Plantagenet, was the second surviving son of Henry III of England and Eleanor of Provence. In his childhood he had a claim on the Kingdom of Sicily, but he never ruled there. In 1265 he was granted all the lands of Simon de Montfort 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. His nickname, Crouchback , refers to his participation in the Ninth Crusade.
Edmund was born in London. He was a younger brother of Edward I of England, Margaret of England, and Beatrice of England, and an older brother of Katherine of England.
