Simon de Montfort's Parliament
The Parliament that Simon de Montfort convened in January 1265 was not England's first great council — kings had long gathered their leading barons to discuss affairs of state — but it was the first assembly explicitly to include representatives of the counties and boroughs alongside the magnates of Church and state. Two knights from each shire and two burgesses from each of the principal towns received writs summoning them to Westminster, creating an assembly that, for the first time in English history, could claim to speak for the realm as a whole rather than merely its landed elite. Simon de Montfort, sixth Earl of Leicester and brother-in-law to Henry III, had risen to lead the baronial reform movement that sought to enforce the Provisions of Oxford (1258), a programme of radical constitutional reform that would have subjected the king's government to permanent baronial oversight. The Second Barons' War (1264–67) was the violent collision between this reform programme and Henry's determination to recover his prerogatives. When de Montfort captured Henry III and his son Prince Edward at the Battle of Lewes in May 1264, he briefly controlled England. He governed in the king's name while genuine power rested with himself and a council of nine — and he needed as broad a base of political support as possible. The January 1265 Parliament was partly a propaganda exercise, designed to demonstrate that de Montfort's regime had the backing of the nation. But the precedent it set proved more durable than the regime itself. Prince Edward escaped captivity in May 1265 and rapidly rebuilt royalist support. At the Battle of Evesham on August 4, 1265, de Montfort was killed, his body mutilated by his enemies. His parliamentary experiment seemed finished with him. Yet the idea survived. Edward I, once king in his own right, recognised that representative assemblies could be tools of royal government as well as baronial resistance. His Model Parliament of 1295 — summoned in the famous formulation that 'what concerns all should be approved by all' — became the template for the bicameral Parliament that would develop over the following two centuries. The knights and burgesses de Montfort had summoned became the House of Commons; the magnates became the House of Lords. The twin chambers of modern British democracy trace their ancestry directly to the crisis of 1265. De Montfort's memory was contested from the moment of his death. Henry III ordered his cult suppressed, but popular veneration of 'Good Sir Simon' as a martyr for justice persisted for decades. Modern historians debate how far de Montfort was a genuine constitutional reformer, how far a self-interested magnate who used reforming language to advance his own power. The answer is probably both — but the institutional legacy he accidentally consolidated outlasted all his personal ambitions and contradictions.
