 Because of its support of the Catholic Church during the crusade, the Abbey was also able to buy feudal lands from those who had been excommunicated as Cathar sympathisers.Following many revolts and military reversals, the crusade was rejoined under Louis VIII in 1225 and Caunes was once more in the frame as a stronghold of the Catholic faith.Of particular note was the burning at the stake of the elderly Cathar Bishop or Perfect of Carcassonne, Pierre Isarn in 1226, witnessed by the King.
