2. 1243Paris · ParisOn 4 December 1243, Henry III signed the treaty in Paris, renouncing claims to Normandy, Maine, Anjou, Touraine, and Poitou, retaining only Gascony and certain port rights; Blanche, on behalf of the young Louis IX, accepted the concessions, and the territorial pattern on the continent between England and France was thereby redrawn.
