Abstract
The Occitanian Cathars were among the most successful heretics in medieval Europe. In order to combat this heresy the Catholic Church ordered preaching campaigns, passed ecclesiastic legislation, called for a crusade and eventually turned to the new mechanism of the Inquisition. Understanding why the Cathars were so popular in Occitania and why the defeat of this heresy required so many different mechanisms entails exploring the development of Occitanian culture and the wider world of religious reform and enthusiasm. This paper will explain the origins of popular piety and religious reform in medieval Europe before focusing in on two specific movements, the Patarenes and Henry of Lausanne, the first of which became an acceptable form of reform while the other remained a heretic. This will lead to a specific description of the situation in Occitania and the attempts to eradicate the Cathars with special attention focused on the way in which Occitanian culture fostered the growth of Catharism. In short, Catharism filled the need that existed in the people of Occitania for a reformed religious experience. Despite all the church’s active attempts to quell the Cathars, it was only when a new group of religious men providing an orthodox solution to the religious need of Occitanians and a new political culture came to Occitania that the Cathars were finally eliminated from the fabric of society.
