Dictum of Kenilworth The Dictum of Kenilworth, issued on 31 October 1266, was a pronouncement designed to reconcile the rebels of the Barons' War with the royal government of England. After the baronial victory at the Battle of Lewes in 1264, Simon de Montfort took control of royal government, but at the Battle of Evesham the next year Montfort was killed, and King Henry III restored to power. A group of rebels held out in the stronghold of Kenilworth Castle, however, and their resistance proved hard to crush.
