The Second Barons' War (1264–1267) was a civil war in England between the forces of a number of barons led by Simon de Montfort against the royalist forces of King Henry III, led initially by the king himself and later by his son Prince Edward, the future King Edward I.
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 by widespread famine.
French-born Simon de Montfort, Earl of Leicester, 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’s sister Eleanor without Henry's permission, and without the agreement of the English Barons (ordinarily necessary since it was a matter of state). As a result, a feud developed between de Montfort and Henry. 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 Dynasty 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 de Montfort 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.
Seeking to restore his position, in 1259 Henry purchased the support of King Louis IX of France by the Treaty of Paris, agreeing to accept the loss of the lands in France that had been seized from him and from his father King John by Louis and his predecessors since 1202, and to do homage for those that remained in his hands. In 1261 he obtained a papal bull releasing him from his oath, and set about reasserting his control of government. The baronial opposition responded by summoning their own Parliament and contesting control of local government, but with civil war looming they backed down and de Montfort fled to France, while the other key opposition leader, Richard de Clare, Earl of Hertford and Gloucester, switched over to the King's side. Under the Treaty of Kingston an arbitration system was agreed to resolve outstanding disputes between Henry and the barons, with de Clare as the initial arbiter and the option of appealing his verdicts to Louis IX. However, continued Poitevin influence and the failures and renewal of provocative policies by Henry's government soon inflamed hostility once more. The King's position was further weakened by the death of Richard de Clare and the succession of his son Gilbert, who sided with the opposition, and by the reversal of the papal annulment of his oath to uphold the Provisions.
In April 1263 Simon de Montfort returned to England and gathered a council of dissident barons at Oxford. Fighting broke out in the Welsh Marches, and by the autumn both sides had raised considerable armies. De Montfort marched on London and the city rose in revolt, trapping the King and Queen at the Tower of London. They were taken prisoner and de Montfort assumed effective control of government in Henry's name. However, his support soon fractured and Henry was able to regain his liberty. With violent disorder spreading and the prospect of all-out war, Henry appealed to Louis for arbitration, and after initial resistance de Montfort consented to this. In January 1264, by the Mise of Amiens, Louis declared in Henry's favour, annulling the Provisions of Oxford. Some of the barons who had previously opposed Henry acquiesced in this verdict, but a more radical faction led by de Montfort prepared to resist any reassertion of royal power, and both they and the king gathered their forces for war.
Course of the war
Fighting resumed in February 1264, with attacks by Simon de Montfort's sons Henry and Simon on royalist supporters in the Welsh Borders. In April the elder Simon de Montfort, in control of London, assembled his forces at St Albans and marched to relieve Northampton, which was under siege by the royalists, but was too late to prevent the town's capture by betrayal. He then moved into Kent and laid siege to the royal stronghold of Rochester Castle, but on hearing reports of a royal advance on London he withdrew most of his forces from the siege to confront this threat. King Henry, however, bypassed the capital and the rebel army and raised the siege of Rochester, before capturing Tonbridge and Winchelsea from the rebels.
Moving into Sussex, Henry was confronted by de Montfort, who had led his army out from London in pursuit. In the Battle of Lewes on 14 May 1264, Henry was defeated and taken prisoner by de Montfort, along with his son Prince Edward and his brother, Richard of Cornwall. While Henry was reduced to a figurehead king, de Montfort broadened parliamentary representation to include groups beyond the nobility, members from each county of England and many important towns. Henry and his son Edward remained effective prisoners, but the radicalism of de Montfort's subversion of traditional order once again led to a fracturing of his brittle base of support.
In May 1265 Prince Edward escaped from de Montfort's custody at Hereford and assembled a new royalist army at Worcester. He attracted defectors from the baronial cause, most importantly Gilbert de Clare, de Montfort's most powerful ally. Simon was blocked from moving east from Hereford by royalist control of the crossings of the River Severn, completed by Edward's capture of Gloucester. Moving into Wales, de Montfort forged an alliance with the Welsh Prince Llywelyn ap Gruffudd, who provided him with soldiers. An attempt by Simon to ship his forces across the Severn estuary from Newport was thwarted when his transports were destroyed by royalist warships, and he returned to Hereford.
Prince Edward meanwhile attacked de Montfort's seat at Kenilworth Castle, where the younger Simon de Montfort had been gathering forces to assist his father. The baronial army was caught asleep in camp by a surprise attack in the early hours of 1 August and massacred. The survivors took refuge inside the castle and Edward initiated the long Siege of Kenilworth. The elder Simon had taken advantage of Edward's move to Kenilworth to cross the Severn at Kempsey, and was on his way to join his son when he was intercepted and decisively defeated by the royalists in the Battle of Evesham on 4 August. Simon and his son Henry were killed in the fighting, and King Henry, whom de Montfort had taken into battle with him, was freed.
The victory at Evesham left the royalists in a dominant position, but the rebels continued to defend their strongholds, most notably Kenilworth, and the war dragged on. In 1266 the King was persuaded to seek a compromise settlement, and a commission of bishops and barons drafted a proclamation known as the Dictum of Kenilworth, issued on 31 October. This set terms under which rebels could secure a pardon and regain their confiscated lands, on payment of a heavy fine. The proposal was initially rejected by the rebels, but on 14 December 1266 hunger finally compelled the defenders of Kenilworth to surrender, accepting the terms of the Dictum. In April 1267 Gilbert de Clare turned again to revolt and occupied London. He was reconciled with Henry by a negotiated settlement in June, which eased the terms of the Dictum, enabling repentant rebels to regain their lands before rather than after paying their fines. That summer also saw the negotiated surrender of the last group of defiant rebels, who had been holding out in the Fens at the Isle of Ely. The total casualties of the war are estimated at 15,000.
