Treaty of Corbeil settles French and Aragonese borders

1254

Louis IX and James I of Aragon renounced each other's historic claims in the former Marca Hispanica, effectively setting the Franco-Aragonese border in the Pyrenees. The treaty ended residual Carolingian claims and gave Catalonia a stable northern frontier. The agreement was characteristic of Louis's preference for negotiated settlements over military adventures, a trait that earned him the respect of even his rivals.
