Second Baron's War, 1264-1267
Civil war between Henry III and the Barons led by Simon de Montfort. The rebellion was caused by increased financial demands made by Henry III. Initially, de Montfort was triumphant, capturing Henry III at the battle of Lewes, but his victory was shortlived. The Barons argued amongst themselves, and Gilbert, earl of Gloucester and Roger Mortimer joined the Royalists, by then led by Prince Edward, the future Edward I. At the battle of Evesham (1265), the rebels were defeated, Simon de Montfort killed, and Henry III rescued. Peace was proclaimed on 16 September 1265, but the siege of Kenilworth, where de Montfort's son was besieged, went on for longer, while the last resistance was not ended until 1267.
