The Mise [a] of Lewes was a settlement made on 14 May 1264 between King Henry III of England and his rebellious barons, led by Simon de Montfort. The settlement was made on the day of the Battle of Lewes, one of the two major battles of the Second Barons' War. The conflict between king and magnates was caused by dissatisfaction with the influence of foreigners at court and Henry's high level and new methods of taxation. In 1258 Henry was forced to accept the Provisions of Oxford, which essentially left the royal government in the hands of a council of magnates, but this document went through a long series of revocations and reinstatements. In 1263, as the country was on the brink of civil war, the two parties agreed to submit the matter to arbitration by the French king Louis IX. Louis was a firm believer in the royal prerogative, and decided clearly in favour of Henry. The outcome was unacceptable for the rebellious barons, and war between the two parties broke out almost immediately.


The Mise of Lewes was signed on the day of Montfort's victory at the Battle of Lewes, though it is not known whether it happened during or after the battle. Neither are the terms of the document known, though it seems clear that they involved conditions for further negotiations. These efforts at a permanent settlement fell through, however, and the support for Montfort's government gradually eroded. Henry's oldest son, Edward – the later King Edward I  started a military campaign that ended in the Battle of Evesham in August 1265, where Montfort was defeated and killed. Parts of the baronial resistance still held out, but by the end of 1266 the final besieged garrison at Kenilworth Castle surrendered. The rebels were given pardons according to terms set out in the Dictum of Kenilworth.


By 1264, the reign of Henry III was deeply troubled by disputes between the king and his nobility. The conflict was caused by several factors: the influence of foreigners at court, a wasteful war over the crown of Sicily, and a personal dispute between King Henry and Simon de Montfort, Earl of Leicester. In 1258, Henry was forced to accept the so-called Provisions of Oxford, whereby he effectively surrendered control of royal government to a council of magnates. In 1259 the baronial program of reform was further elaborated upon in the Provisions of Westminster. [2] The provisions remained in effect for three years; it was not until 1261 that Henry was able to move against the opposition. Receiving the papal annulment of the provisions his emissaries had campaigned for, he re-assumed control of government. [3] Over the next two years, however, discontent re-emerged over Henry's style of government. He failed to be reconciled with Montfort, and he also alienated Gloucester's son and heir Gilbert. In April 1263 Montfort returned to England after a long stay in France, and reignited the reform movement. [4] On 16 July Henry was surrounded by rebel forces in the Tower of London, and once more forced to accept the conditions of the provisions. [5] Prince Edward the later King Edward I – now took control of the situation. In October Edward took Windsor Castle, and the baronial alliance started to break up. [6]

Cornered, Montfort had to accept a truce and agree to submit the issue to arbitration by the French king Louis IX. By the Mise of Amiens, Louis decided entirely in favour of Henry, and repudiated the provisions. [7] The settlement did not present a solution to the conflict, but rather a recipe for further problems. The one-sided decision for the king and against the barons left Montfort with little choice but armed rebellion. [8] Hostilities started already in February, when Montfort's sons, Henry and Simon the Younger, attacked the possessions of Roger Mortimer in the Marches. [9] Henry summoned the feudal army, and the royal forces won an important victory at Northampton, where the younger Simon was captured. [10] Montfort was still in control of London, as Henry regained control over Kent and Sussex. Montfort marched out of London to negotiate, but the terms involving maintaining the provisions were rejected by the king. [11] The only option remaining was to fight, and the two forces met at Lewes on 14 May 1264. In spite of inferior numbers, the baronial forces led by Simon de Montfort won the battle. Edward, commanding the right wing, quickly defeated the London forces. When he set out in pursuit of the fleeing soldiers, however, he left the rest of the royal army exposed. The baronial forces took advantage of the situation, and soon won the day. [12]


Since no documents exist to confirm the content of the Mise of Lewes, there has been much debate among historians over its content, and the circumstances under which it was written. Noël Denholm-Young, in an article published in 1933, made a conjecture on what the main points of the agreement were. The first point, according to Denholm-Young, was that Prince Edward and his cousin, Henry of Almain, should be given over to the barons as hostages. Secondly, those of the baronial party who had been taken hostage at Northampton were to be released. Thirdly, those who had taken hostages from the royalist party at the Battle of Lewes were to receive ransom. Finally, it was agreed that a committee of French clergy and nobles should arbitrate over a permanent settlement. [13] This interpretation has been largely followed by later historians. [14] [15]

One contentious point in Denholm-Young's article was his assertion that there was no mention of the Provisions of Oxford in the Mise of Lewes. [16] This was an idea that John Maddicott strongly contested in a 1983 article. According to Maddicott, the provisions had been at the centre of Montfort's opposition over the last six years, and it was unlikely that he would give them up so easily. [17] Nevertheless, Montfort showed willingness to negotiate the terms of the provisions. As such, the Mise of Lewes was a moderate document; Montfort wanted to avoid a repetition of the situation after the Mise of Amiens. Rather it was external circumstances outside of Montfort's control that led to the eventual failure of the negotiations between the royalists and the barons. [18]

This interpretation was challenged by David Carpenter two years later, in 1985. Montfort had no intention to compromise with the royalists at all, according to Carpenter. [19] In Carpenter's version of events, the Mise of Lewes was written while the battle was still ongoing, not after the battle was over, as previously assumed. [20] This put Montfort in a situation where concessions were necessary, in order to bring hostilities to a halt as soon as possible. Once the battle was over and government in Montfort's hands, he had no longer any interest in reaching a compromise with the royalists, and that was why hostilities continued. [21] This dating of the document, however, has later been disputed by D. W. Burton, who maintains that the document was in fact signed after the battle was concluded. [22]


The government led by Montfort soon ran into problems; he faced poor finances, general disorder, and the threat of invasion from exiled royalists in France. [23] It was decided since the French arbitration committee had come to nothing to set up a provisional administration, consisting of Montfort, the young Earl of Gloucester, and the Bishop of Chichester. These three were to elect a council of nine, to govern until a permanent settlement could be reached. [24] By the Peace of Canterbury in August, Henry and Edward were forced to accept even stricter terms than those of the Mise of Lewes. According to this new agreement, the current form of government was to remain in force throughout the reign of King Henry, and into that of Edward. [25] To keep the borders safe, Montfort had been forced to release Roger Mortimer and other royalist Marcher lords after the Battle of Lewes. [26] In December, Montfort forced Mortimer, Roger de Clifford and Roger de Leybourne to promise to leave the country for Ireland. [27] Then, in January, he summoned a parliament at Leicester which became known as Montfort's Parliament, including representatives from the shires and boroughs; an innovation in English government. Here Montfort secured the support of the community of the realm for his continued reign. [28]

Montfort's success was illusory, however. The terms of the Peace of Canterbury were rejected by a papal legate in negotiations at Boulogne. [29] Meanwhile, the Marcher lords did not leave the country, and remained a thorn in the side of the regime. [30] The triumvirate at the head of government broke up when the Earl of Gloucester defected to the royalist side. [31] In May, Edward was able to escape captivity, with Gloucester's help. [32] Edward started on a campaign of re-conquest, while Montfort was forced to suppress a rebellion in the Marches. He succeeded only by making large concessions to Llewelyn, and then moved east to join forces with his son Simon. [33] Edward, however, routed the younger Simon at Kenilworth Castle. On 4 August 1265 Montfort found himself trapped at Evesham, forced to give battle with a much smaller army than the royals. [33] The battle soon turned into a massacre; Montfort himself was killed and mutilated on the field. [34] Even with Montfort dead resistance remained, particularly at the virtually impregnable Kenilworth Castle. In October 1266 the Dictum of Kenilworth set down terms by which the rebels could obtain pardons, and by the end of the year the garrison surrendered. [35]


a. ^ A "mise" in this context is a settlement by agreement. The use of the word in this sense is very rare in English, and is normally reserved for the Mise of Lewes and the Mise of Amiens from earlier the same year. It is the feminine past participle of the French verb mettre (to put), and is pronounced /ˈmz/ . [36]

In 1259, he briefly sided with a baronial reform movement, supporting the Provisions of Oxford. After reconciliation with his father, however, he remained loyal throughout the subsequent armed conflict, known as the Second Barons' War. After the Battle of Lewes, Edward was hostage to the rebellious barons, but escaped after a few months and defeated the baronial leader Simon de Montfort at the Battle of Evesham in 1265. Within two years the rebellion was extinguished and, with England pacified, Edward joined the Ninth Crusade to the Holy Land. He was on his way home in 1272 when he was informed that his father had died. Making a slow return, he reached England in 1274 and was crowned at Westminster Abbey.

However, Edward pursued his quarry off the battlefield and left Henry's men exposed. Henry was forced to launch an infantry attack up Offham Hill where he was defeated by the barons' men defending the hilltop. The royalists fled back to the castle and priory and the King was forced to sign the Mise of Lewes, ceding many of his powers to Montfort.

The barons sought to force the king to rule with a council of barons rather than through his favourites. The war also featured a series of massacres of Jews by de Montfort's supporters including his sons Henry and Simon, in attacks aimed at seizing and destroying evidence of baronial debts. To bolster the initial success of his baronial regime, de Montfort sought to broaden the social foundations of parliament by extending the franchise to the commons for the first time. However, after a rule of just over a year, de Montfort was killed by forces loyal to the king in the Battle of Evesham.

The Ordinances of 1311 were a series of regulations imposed upon King Edward II by the peerage and clergy of the Kingdom of England to restrict the power of the king. The twenty-one signatories of the Ordinances are referred to as the Lords Ordainers, or simply the Ordainers. English setbacks in the Scottish war, combined with perceived extortionate royal fiscal policies, set the background for the writing of the Ordinances in which the administrative prerogatives of the king were largely appropriated by a baronial council. The Ordinances reflect the Provisions of Oxford and the Provisions of Westminster from the late 1250s, but unlike the Provisions, the Ordinances featured a new concern with fiscal reform, specifically redirecting revenues from the king's household to the exchequer.
