Catharism
Despite being a priest in a Roman Catholic church Pierre Clergue was a staunch Albigensian having been converted by the parfait Guillaume Authié. For many years he played an important role by convincing the inquisition to ignore Montaillou, despite its being filled with heretics. This changed about 1300 when Pierre Clergue began to inform on some members of his parish. In 1308 he played a central role in the inquisition's move to arrest the entire adult population of the town. Pierre decided which villagers would be freed and which punished. He used this power to satisfy personal grievances. Despite this he and his brother continued to provide shelter and aid to certain Cathars.
