Simon de Montfort

Montfort, Simon de (1208?–65), Anglo-French leader who mounted a revolt against King Henry III. The Baron's War, led by de Montfort, followed Henry's annulment (1261) of the Provisions of Oxford which he had been forced to sign in 1258. The war was ended with the capture of the king (1264). The parliament of 1265, summoned by Montfort and including representatives from every shire, town, and borough, was a landmark in English history. In subsequent fighting Montfort was killed at the Battle of Evesham.
