Montfort was killed at the Battle of Evesham later that year, but the idea of inviting both knights and burgesses to parliaments became more popular under Henry's son Edward I.
[3] On 30 April, Hugh Bigod marched into Westminster in the middle of the King's parliament, backed by his co-conspirators, including Simon de Montfort, the Earl of Leicester, and carried out a coup d'état.
[6] They were used to agree upon the raising of taxes which, in the 13th century, were single, one-off levies, typically on movable property, intended to support the King's normal revenues for particular projects.
[7] During Henry's reign, the counties had begun to send regular delegations to these parliaments, and came to represent a broader cross-section of the community than simply the major barons.
[9] These provisions created a smaller council of 15 members, elected solely by the barons, which then had the power to appoint England's justiciar, chancellor and treasurer, and which would be monitored through triennial parliaments.
[21] Initially Montfort's legal arguments held sway, but in January 1264, Louis announced the Mise of Amiens, condemning the rebels, upholding the King's rights and annulling the Provisions of Oxford.
[25] Captured, Henry was forced to pardon the rebel barons and reinstate the Provisions of Oxford, leaving him, as historian Adrian Jobson describes, "little more than a figurehead".
[30] In response, and hoping to win wider support for his government, Montfort summoned a new parliament for 20 January 1265 which continued until mid March that year.
[32] He summoned not only the nobility, senior churchmen and two knights from each county, but also two burgesses from each of the major towns such as York, Lincoln, Sandwich, and the Cinque Ports, the first time this had been done.
[34] The event was overseen by King Henry, and held in the Palace of Westminster, just outside London, which was the largest city in England, and whose continuing loyalty was essential to Montfort's cause.
[35] This parliament was a tactical move by Montfort in an attempt to gather support from the regions, and the historian Jeffrey Hamilton characterises it as "a very partisan assembly, not some sort of proto-democratic representative body".
[37] The business of the parliament focused on enforcing the Provisions of Westminster, in particular its restrictions on the major nobles, and promising judicial help to those who felt they were suffering from unfair feudal lordship.
[40] Edward pursued Montfort's forces through the Welsh Marches, before striking east to attack his fortress at Kenilworth and then turning once more on the rebel leader himself.
