Although the Albigensian Crusade had been concluded with the Treaty of Paris-Meaux in 1229, local resistance continued. The Cathar Church was still able to operate and oppose the terror of the Inquisition that pervaded the Languedoc. In 1233, the Cathar Bishop Guilhabert de Castres asked Raymond de Pereille for permission to make Montségur "the seat and head" (domicilium et caput) of the Cathar Church.[1]
