Catharism was the most successful heresy of the Middle Ages. Flourishing principally in the Languedoc and Italy, the Cathars taught that the world is evil and must be transcended through a simple life of prayer, work, fasting, and non-violence. They believed themselves to be the heirs of the true heritage of Christianity going back to apostolic times, and completely rejected the Catholic Church and all its trappings, regarding it as the Church of Satan. Cathar services and ceremonies, by contrast, were held in fields, barns, and in people's homes. Finding support from the nobility in the fractious political situation in southern France, the Cathars also found widespread popularity among peasants and artisans. And, unlike the Church, the Cathars respected women; they played a major role in the movement. Alarmed at the success of Catharism, the Church founded the Inquisition and launched the Albigensian Crusade to exterminate the heresy. While previous Crusades had been directed against Muslims in the Middle East, the Albigensian Crusade was the first Crusade to be directed against fellow Christians, and was also the first European genocide. With the fall of the Cathar fortress of Montségur in 1244, Catharism was largely obliterated, although the faith survived into the early fourteenth century. Today, the mystique surrounding the Cathars is as strong as ever, and Sean Martin recounts their story and the myths associated with them in this lively and gripping book.

The question of the reality of Cathars and other heresies is debated in this provocative collection.

A compelling introduction to the war against the heretics of Languedoc launched in 1209, combined with a description of the political, economic, religious and social conditions of south-western France in the twelfth and thirteenth centuries. Michael Costen shows why the Cathar heresy came to flourish and how the campaign against it developed into a programme of conquest by which an alliance of church and state finally destroyed the heresy and united the region with the newly expanding French kingdom.

The Cathars are one of the most famous heretical movements of the late twelfth and early thirteenth centuries. They infiltrated the highest ranks of society and posed a major threat not only to the Catholic Church but also to secular authorities as well. The movement was finally smashed by the crusade and the inquisitional proceedings that followed. This new study is the first comprehensive history of the Cathars. It addresses major topics in medieval history including heresy, orthodoxy and the Crusades as well as providing a history of the social and political history of Languedoc and the rise of the Capetian dynasty. A fascinating study of the development of radical religious belief and its violent suppression.

Some of the most portentous events in medieval history—the Cathar crusade, the persecution and mass burnings of heretics, the papal inquisition—fall between 1000 and 1250, when the Catholic Church confronted the threat of heresy with force. Moore’s narrative focuses on the motives and anxieties of elites who waged war on heresy for political gain.

A deep-dive into the history, culture, and legacy of the medieval Christian dualist movement, Catharism—as seen in popular novels by Dan Brown and Kate Mosse Centuries after the brutal slaughter of the Cathars by papally endorsed Northern French forces, and their suppression by the Inquisition, the medieval Cathars continue to exert a powerful influence on both popular culture and spiritual seekers. Yet few people know anything of the beliefs of the Cathars beyond vague notions that they believed in reincarnation, were vegetarians, were somehow Gnostic, and had some relation to Mary Magdalene. The Lost Teachings of the Cathars explores the history of this Christian dualist movement between the twelfth and fourteenth centuries, offering a sympathetic yet critical examination of its beliefs and practices. In addition to investigating the Cathars’ origin, their relationship to Gnosticism, and their possible survival of the Inquisition, author Andrew Philip Smith also addresses theories and figures from the Cathars’ recent past. Eccentric esotericists initiated a neo-Cathar revival in the Languedoc which inspired the philosopher Simone Weil. The German Otto Rahn—the real-life Indiana Jones—believed that the Cathars were protectors of the Holy Grail and received support from Heinrich Himmler. Meanwhile, English psychiatrist Arthur Guirdham became convinced that he and a circle of patients had all been Cathars in previous lives. Tourists flock to the Languedoc to visit Cathar country. Bestsellers such as Kate Mosse’ timeslip novel Labyrinth continue to fascinate readers. But what did the Cathars really believe and practice?
