The First Barons' War (1215–1217) was a civil war in the Kingdom of England in which a group of rebellious major landowners (commonly referred to as barons) led by Robert Fitzwalter with a French army under the future Louis VIII of France, waged war against King John of England.The war resulted from King John's refusal to accept and abide by Magna Carta, which he had sealed on 15 June 1215.
After John's death the ambitions of the French crown prince Louis to be King of England meant that many of the rebels switched sides and the war dragged on. The war ended after French defeats at Lincoln and Sandwich in 1217 and Louis was forced to sign the Treaty of Lambeth. This formalised the end of the civil war and the departure of the French from England.
King John in June 1215 was forced to put his seal to "The Articles of the Barons" by a group of powerful barons who could no longer stand John's failed leadership and despotic rule. The king's Great Seal was attached to it on 15 June 1215. In return, the barons renewed their oaths of fealty to King John on 19 July 1215. A formal document to record the agreement was created by the royal chancery on 15 July: this was the original Magna Carta. "The law of the land" is one of the great watchwords of Magna Carta, standing in opposition to the king's mere will.
The Magna Carta of 1215 contained clauses which in theory noticeably reduced the power of the king, such as clause 61, the "security clause". This clause allowed a group of 25 barons to override the king at any time by way of force, a medieval legal process called distraint that was normal in feudal relationships but had never been applied to a king. After a few months of half-hearted attempts to negotiate in the summer of 1215, open warfare broke out between the rebel barons and the king and his supporters.
Course of eventsEdit
Louis invited and welcomedEdit
The war began over Magna Carta but quickly turned into a dynastic war for the throne of England. The rebel barons, faced with a powerful king, turned to Louis, son and heir apparent of King Philip II of France and grandson-in-law of King Henry II of England. The Norman invasion had occurred only 149 years before, and the relationship between England and France was not so simply adversarial as it later became. The contemporary document called the annals of Waverley sees no contradiction in stating that Louis was invited to invade in order to "prevent the realm being pillaged by aliens."
At first, in November 1215, Louis simply sent the barons a contingent of knights to protect London. However, even at that stage he also agreed to an open invasion, despite discouragement from his father and from Pope Innocent III. This came in May 1216, when watchmen on the coast of Thanet detected sails on the horizon, and on the next day, the King of England and his armies saw Louis's troops disembark on the coast of Kent.
John decided to escape to the Saxon capital of Winchester, and so Louis had little resistance on his march to London. He entered London, also with little resistance, and was openly received by the rebel barons and citizens of London and proclaimed (though not crowned) king at St Paul's Cathedral. Many nobles gathered to give homage to him, including Alexander II of Scotland, who held fiefs in England.
Many of John's supporters, sensing a tide of change, moved to support the barons. Gerald of Wales remarked: "The madness of slavery is over, the time of liberty has been granted, English necks are free from the yoke."
In pursuit of John, Louis led his army south from London on June 6, arriving the following day in Reigate where he found the castle abandoned. He moved onwards to Guildford Castle on June 8, which surrendered immediately. Farnham Castle initially closed its gates, but then it too surrendered as the French started to lay siege. He only met resistance when he reached Winchester Castle on June 14 – it fell after a ten day siege. Louis' campaign continued and by July about a third of England was under his control. 
First siege of DoverEdit
In the meantime, the King of France taunted his son for trying to conquer England without first seizing its key: Dover. The royal castles at Canterbury and Rochester, their towns, and indeed, most of Kent had already fallen to Louis but when he did move on to Dover Castle on 25 July it was prepared. Its constable, Hubert de Burgh, had a well-supplied garrison of men.
The first siege began on 19 July, with Louis taking the high ground to the north of the castle. His men successfully undermined the barbican and attempted to topple the castle gate, but De Burgh's men managed to repel the invaders, blocking the breach in the walls with giant timbers. (After the siege the weak northern gate was blocked and tunnels were built in that area, to St John's Tower, and the new Constable's Gate and Fitzwilliam's Gate.) In the meantime Louis's occupation of Kent was being undermined by a guerrilla force of Wealden archers raised and led by William of Cassingham.
After three months spent besieging the castle, and with a large part of his forces diverted by the siege, Louis called a truce on 14 October and soon after returned to London.
Sieges of Windsor and RochesterEdit
Apart from Dover, the only castle to hold out against Louis was that at Windsor, where 60 loyalist knights survived a two-month siege, despite severe damage to the structure of its lower ward (immediately repaired in 1216 by Henry III, who further strengthened the defences with the construction of the western curtain wall, much of which survives today). This is possibly due to its having been already besieged by the barons in 1189, less than 30 years earlier.
In 1206, John had spent £115[a] on repairs to Rochester Castle, and he had even preemptively held it during the year of the negotiations leading up to Magna Carta, but the Charter's terms had forced him to hand it back into the custody of Stephen Langton, Archbishop of Canterbury, in May 1215. The rebel barons had then sent troops under William d'Aubigny to the castle, to whom its constable Reginald de Cornhill opened the castle's gates. Thus, during October 1215 on his marching from Dover to London, John found Rochester in his way and on 11 October began besieging it in person.
The rebels were expecting reinforcements from London but John sent fire ships out to burn their route in, the city's bridge over the Medway. Robert Fitzwalter rode out to stop the king, fighting his way onto the bridge but eventually being beaten back into the castle. John also sacked the cathedral, took anything of value and stabled his horses in it, all as a slight to Langton. Orders were then sent to the men of Canterbury.
Five siege engines were then erected and work carried out to undermine the curtain wall. By one of these means the king's forces entered and held the bailey in early November, and began attempting the same tactics against the keep, including undermining the south-east tower. The mine-roof was supported by wooden props, which were then set alight using pig-fat. On 25 November 1215 John had sent a writ to the justiciars saying "Send to us with all speed by day and night, forty of the fattest pigs of the sort least good for eating so that we may bring fire beneath the castle". The fire thus created caused one entire corner of the keep to collapse. The rebels withdrew behind the keep's cross-wall but still managed to hold out. A few were allowed to leave the castle but on John's orders had their hands and feet lopped off as an example.
Winter was now setting in, and the castle was taken on 30 November by starvation and not by force. John set up a memorial to the pigs and a gallows with the intention of hanging the whole garrison, but one of his captains (Savari de Mauléon) persuaded him not to hang the rebels since hanging those who had surrendered would set a precedent if John ever surrendered – only one man was actually hanged (a young bowman who had previously been in John's service). The remainder of the rebel barons were taken away and imprisoned at various royal-held castles, such as Corfe Castle. Of the siege, the Barnwell chronicler wrote "No one alive can remember a siege so fiercely pressed and so manfully resisted" and that, after it, "There were few who would put their trust in castles".
Death of King JohnEdit
On 18 October 1216, John contracted dysentery, which would ultimately prove fatal. He died at Newark Castle, Nottinghamshire, and with him the main reason for the fighting. Louis now seemed much more of a threat to baronial interests than John's nine-year-old son, Prince Henry. While Eleanor of Brittany, the grown daughter of John's late elder brother Geoffrey, imprisoned by John since 1202, posed another potential candidate for the crown, the barons passed her over just like their ignorance of her conditions when Magna Carta was issued, leaving her still in prison.
Pierre des Roches, Bishop of Winchester, and a number of barons rushed to have the young Henry be crowned as King of England. London was held by Louis (it was his seat of government) and therefore could not be used for this coronation so, on 28 October 1216, they brought the boy from the castle at Devizes to Gloucester Abbey in front of a small attendance presided over by a Papal Legate, Guala Bicchieri (d. 1227, Bishop of Vercelli, papal legate in England 1216–18). They crowned Henry with a band of gold made from a necklace.
On 12 November 1216 Magna Carta was reissued in Henry's name with some of the clauses omitted, including clause 61. The revised charter was sealed by the young king's regent William Marshal. A great deal of the country was loyal to Prince Louis, with the southwest of England and the Midlands favouring Henry. Marshal was highly respected and he asked the barons not to blame the child Henry for his father's sins. The prevailing sentiment, helped by self-interest, disliked the idea of depriving a boy of his inheritance. Marshal also promised that he and the other regents would rule by Magna Carta. Furthermore, he managed to get support from the Pope, who had already excommunicated Louis.
William Marshal slowly managed to get most barons to switch sides from Louis to Henry and attack Louis. The two opposing sides fought for about a year. On 6 December 1216 Louis took Hertford Castle but allowed the defending knights to leave with their horses and weapons. He then took Berkhamsted Castle in late December, again allowing the royal garrison to withdraw honourably with their horses and weapons.
By early 1217, Louis decided to return to France for reinforcements. He had to fight his way to the south coast through loyalist resistance in Kent and Sussex, losing part of his force in an ambush at Lewes, with the remainder pursued to Winchelsea and were only saved from starvation by the arrival of a French fleet.
Since the truce had been arranged with Dover, the Dover garrison had repeatedly disrupted Louis's communication with France, and so Louis sailed back to Dover to begin a second siege. The French camp set up outside Dover Castle in anticipation of the new siege was attacked and burned by William of Cassingham just as the fleet carrying the reinforcements arrived. Louis was forced to land at Sandwich and march to Dover, where he began a second siege in earnest on 12 May 1217. This new siege diverted so much of Louis's forces that Marshal and Falkes de Breauté were able to attack and heavily defeat pro-Louis barons at Lincoln Castle on 15 May or 20 May 1217, in what became known as the Second Battle of Lincoln.
Marshal prepared for a siege against London next. In the meantime, Louis suffered two more heavy defeats, this time at sea, at the Battle of Dover and Battle of Sandwich in the Straits of Dover, this time at the hands of William's ally and Dover's constable Hubert de Burgh. Louis' new reinforcement convoy, under Eustace the Monk, was destroyed, making it nearly impossible for Louis to continue fighting.
After a year and a half of war, most of the rebellious barons had defected. As a result of this and the defeat of the French in 1217, Louis was forced to negotiate. A few of Henry's supporters held out for unconditional surrender, but the Earl of Pembroke successfully argued for the more moderate terms.
At the Treaty of Lambeth which was signed on 11 September 1217, Louis had to give up his claim to be the King of England and agreed he had never been the legitimate king. The principal provisions of the treaties were an amnesty for English rebels, nevertheless the barons who had joined Louis were made to pay the French prince 10,000 marks to expedite his withdrawal. Louis surrendered the few remaining castles that he had held, and exhorted to his allies; Scottish and Welsh troops under Alexander II and Llywelyn the Great respectively to lay down their arms. Louis also undertook not to attack England again.
