Louis's short reign was marked by an intervention using royal forces into the Albigensian Crusade in southern France that decisively moved the conflict towards a conclusion.
He was the first Capetian king to grant appanages to his younger sons on a large scale.
He died in 1226 and was succeeded by his son Louis IX.
