"The reign of Henry III is most remembered for the constitutional crisis in this period of civil strife, which was provoked ostensibly by Henry III's demands for extra finances, but which marked a more general dissatisfaction with Henry's methods of government on the part of the English barons, discontent which was exacerbated at a more popular level by widespread famine. French-born Simon de Montfort had originally been one of the foreign upstarts so loathed by many lords as Henry's foreign councillors, but having inherited through his mother the English title Earl of Leicester, he married Henry\u2019s sister Eleanor with Henry's permission, but without the agreement of the English Barons, since it was a matter of the state: a feud developed between the two. Their relationship reached a crisis in the 1250s, when de Montfort was put on trial for actions he took as lieutenant of Gascony, the last remaining Plantagenet lands across the English Channel. Henry also became embroiled in funding a war against the Hohenstaufen in Sicily on behalf of Pope Innocent IV in return for the Hohenstaufen title King of Sicily for his second son Edmund. This made many barons fearful that Henry was following in the footsteps of his father King John and, like him, needed to be kept in check. When Henry's treasury ran dry, Innocent withdrew the title, and in regranting it to Charles of Anjou in effect negated the sale. Simon, earl of Leicester, became leader of those who wanted to reassert the Magna Carta and force the king to surrender more power to the baronial council. In 1258, initiating the move toward reform, seven leading barons forced Henry to agree to the Provisions of Oxford, which effectively abolished the absolutist Anglo-Norman monarchy, giving power to a council of twenty-four barons to deal with the business of government and providing for a great council in the form of a parliament every three years, to monitor their performance. Henry was forced to take part in the swearing of a collective oath to uphold the Provisions of Oxford. In the following years, those supporting de Montfort, including his circle of Franciscan advisors centered on Adam Marsh, and those loyal to the king grew more and more polarised; Henry obtained a papal bull in 1261 exempting him from his oath, and both sides began to raise armies, the Royalists under Edward Longshanks, Henry's eldest son. A civil war followed."@en . . "Anti-monarchy forces"@en . . . . "government of Henry III"@en . . . "monarchic victory"@en . . . . . .
