(France). 
11 February 1225 
Henry III 'confirms' Magna Carta and the Charter of the Forest. This means that he reaffirms his intention to govern England in accordance with the laws contained in 
the charters. 
1254 
Henry III arranges with the pope that his son, Edmund, should become king of Sicily. He agrees to pay £90,000 to the pope, but parliament refuses to raise the sum. 
1258 
The pope threatens to excommunicate Henry III if he does not pay £90,000 to the papacy. Henry III had promised this sum so that his son could become king of Sicily. 
 
June 1258 
Henry III desperately seeks advice from his barons concerning the £90,000 he owes to the pope. Henry's barons agree to help their king, if he agrees to accept major political reforms. Discussions take place at the 'Mad Parliament' held at Oxford. 
June-July 1258 
Henry agrees to the Provisions of Oxford. The king is forced to rule with the advice of a council. It is also decided that parliament should meet three times a year to review political developments. 
October 1259 
Henry agrees to the Provision of Westminster, a series of twenty-four major legal reforms similar to Magna Carta in their scope and importance. 
29 April 1261 
The pope condemns the reforms that have been forced upon Henry III. All barons in England are absolved from any oaths they have taken to ensure that the reforms are upheld. 
14 May 1264 
Simon de Montfort and the rebel barons defeat a royal army at the battle of Lewes, taking King Henry III captive. Simon de Montfort is now the unofficial ruler of England. 
 
January 1265 
Simon de Montfort calls a parliament to discuss the terms for the king's release. He orders knights from each of England's shires, and representatives from England's towns, to attend. 
4 August 1265 
King Henry III defeats Simon de Montfort and the rebels at the battle of Evesham. Simon de Montfort is killed, marking an end to the reform movement that had begun in 1258. 
30 October 1266 
Dictum of Kenilworth marks the royalist recovery, but in a manner of reconciliation. Many of the reforms issued since 1258 are now issued in the name of the king. Henry III dies, and is succeeded by his son, King Edward I. 
16 November 1272 1294 
King Philip IV of France declares Edward I's territories in Gascony forfeit, because Edward refused to attend the French court up following a summons by Philip. War breaks out between England and France. 
 
7 July 1297 
Two important barons, Roger Bigod and Humphrey de Bohun, refused Edward I's order to draw up a muster list - those summoned by the king for military service. The king was forced to offer wages for military service, instead of relying on 
feudal obligations. 
30 July 1297 
Royal writs (instructions) order the collection of tax set at a very high rate. The king falsely claimed that the tax had been granted with the assent of the whole laity of the realm. In reality, the king ordered the collection of a tax without the assent of parliament. 
22 August 1297 
Roger Bigod and Humphrey de Bohun appeared at the exchequer - which managed the kingdoms finances - and stated that the people of England would 
not pay the tax. 
October 1297 
The king's 'bad' tax was cancelled, and replaced with a new tax, which was set at a lower rate and properly granted by parliament. 
March 1300 
Edward I confirmed Magna Carta, and agreed to a new set of political reforms put forward by the rebel barons in a document known as 'Articuli super cartas', which means 'Articles in addition to Magna Carta and the Charter of the Forest'. This document set out in detail how Magna Carta could be enforced to prevent the king from breaking its laws. 
1 January 1306 
The pope condemns the 'Articuli super cartas', releasing Edward I from his obligation to follow the rules set out in this new document.
