Henry III
/ˌhenri ðə ˈθɜːd/
/ˌhenri ðə ˈθɜːrd/
- (1207-72) king of England (1216-72) and the son of King John. He was not popular with the barons, who disliked his use of foreign people to advise him and criticized him for poor judgement in financial matters. In 1264, Simon de Montfort led a rebellion of the barons and Henry was defeated and put in prison. He took back power in 1265 after a battle in which the rebels were defeated by an army led by Henry's son (later Edward I).
