At the end of the Albigensian Crusade from the northern "barons" against the southern Occitania on a religious pretext (fighting the Cathar heresy), the Count of Toulouse was defeated and concluded the Treaty of Paris in 1229. With this, the Count gave the Rouergue county to his daughter. She married Alphonse de Poitiers, brother of Saint Louis, King of France. Alphonse founded Villefranche on the place of an old village called La Peyrade in 1252.
