Appearing around the year 1000, Catharism was a dissident Christian religion, originating from the East, particularly influential around Toulouse, Carcassonne, Béziers and Albi. The region therefore became a refuge for the Cathars when the Church pursued them during the Albigensian crusade, all the way to the heights of Montségur. It is this saga that the castles of Cathar country recount.
