Paris, Treaty of 1259
Paris, Treaty of (1259)
a treaty concluded in 1258 between Henry III of England and Louis IX of France. Under the treaty, which was ratified in 1259, Henry III renounced his claim to Normandy, Maine, Anjou, Touraine, and Poitou, which had been lost by John Lackland, his predecessor. He remained, however, the de facto ruler of Aquitaine, a duchy in vassalage to the French king. Louis IX was to pay a considerable sum of money to Henry III, to support the latter’s struggle against the English barons. The treaty played an important role in the centralization of the French state.
