The Mise[a] of Amiens ([miz ɒv a.mjɛ̃]) was a settlement given by King Louis IX of France on 23 January 1264 in the conflict between King Henry III of England and his rebellious barons, led by Simon de Montfort. Louis' one-sided decision for King Henry led directly to the hostilities 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 of taxation. In 1258 Henry was forced to accept the Provisions of Oxford that essentially left 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 was a firm believer in the royal prerogative and decided clearly in favour of Henry.[b]
The outcome was unacceptable for the rebellious barons, and war between the two parties broke out almost immediately after the announcement of the settlement. After a victory at the Battle of Lewes in May 1264, Montfort took over control of government, but the success was short-lived. 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 garrison at Kenilworth Castle surrendered. The rebels were given pardons according to terms set out in the Dictum of Kenilworth.
