Treaty of Paris (1259)

The Treaty of Paris (1259) was a peace agreement between England and France that concluded decades of territorial conflict. It followed a long history of tensions dating back to the Norman Conquest and intensified by King John’s loss of Normandy in 1204 and his successors’ failed attempts to recover those lands. Pressured by military defeats, internal unrest, and King Louis IX’s desire for continental stability before the launch of the Seventh Crusade, both kingdoms entered negotiations.^[1] The treaty marked a significant turning point but left several issues unresolved, setting the stage for future disputes.
