More than seventy documents, ranging in date from the early eleventh century to the early fourteenth century and representing both orthodox and heretical viewpoints are included.

The struggle over fundamental issues erupted with great fury in the eleventh and twelfth centuries. In this book preeminent medievalist Heinrich Fichtenau turns his attention to a new attitude that emerged in Western Europe around the year 1000. This new attitude was exhibited both in the rise of heresy in the general population and in the self-confident rationality of the nascent schools. With his characteristic learning and insight, Fichtenau shows how these two separate intellectual phenomena contributed to a medieval world that was never quite as uniform as might appear from our modern perspective.

Throughout the Middle Ages and early modern Europe theological uniformity was synonymous with social cohesion in societies that regarded themselves as bound together at their most fundamental levels by a religion. To maintain a belief in opposition to the orthodoxy was to set oneself in opposition not merely to church and state but to a whole culture in all of its manifestations. From the eleventh century to the fifteenth, however, dissenting movements appeared with greater frequency, attracted more followers, acquired philosophical as well as theological dimensions, and occupied more and more the time and the minds of religious and civil authorities. In the perception of dissent and in the steps taken to deal with it lies the history of medieval heresy and the force it exerted on religious, social, and political communities long after the Middle Ages. In this volume, Edward Peters makes available the most compact and wide-ranging collection of source materials in translation on medieval orthodoxy and heterodoxy in social context.

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.

Investigation of the development of the Cathar heresy in south-west France, looking at how and why its growth differed across the regions. The medieval county of Quercy in Languedoc lay between the Dordogne and the Toulousain in south-west France; it played a significant role in the history of Catharism, of the Albigensian crusade launched against the heresy in 1209, and of the subsequent inquisition. Although Cathars had come to dominate religious life elsewhere in Languedoc during the course of the twelfth century, the chronology of heresy was different in Quercy. In the late twelfth century, nearby abbeys were still the main focus of devotional activity; inquisitors' discoveries in the 1240s point to the previous twenty years as the period when Catharism and also the Waldensian heresy took a firm hold, most dramatically in its far north. This study deals with the cultural and political origins of the religious change. Its careful analysis offers a significant re-evaluation of the nature and social significance of religious dissidence, and of its protection and persecution in both the history and historiography of Catharism.

For the third edition, this comprehensive history of the great heretical movements of the Middle Ages has been updated to take account of recent research in the field.

A comparative history of heresy in Latin and Greek Christianity, Judaism, and Islam, spanning the fourth to the sixteenth century.

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.

Replete with terror, passion, and hope, this gripping narrative history explores the intricate mysteries of medieval Europe through the lives of the great heretics whose beliefs and practices challenged the teachings of an all-powerful church. Five centuries of social and spiritual turmoil are covered through a vivid and telling mix of events, personalities, and ideas.

All the known theories and incidents of witchcraft in Western Europe from the fifth to the fifteenth century are brilliantly set forth in this engaging and comprehensive history. Building on a foundation of newly discovered primary sources and recent secondary interpretations, Jeffrey Burton Russell first establishes the facts and then explains the phenomenon of witchcraft in terms of its social and religious environment, particularly in relation to medieval heresies. Russell treats European witchcraft as a product of Christianity, grounded in heresy more than in the magic and sorcery that have existed in other societies. Skillfully blending narration with analysis, he shows how social and religious changes nourished the spread of witchcraft until large portions of medieval Europe were in its grip, "from the most illiterate peasant to the most skilled philosopher or scientist." A significant chapter in the history of ideas and their repression is illuminated by this book. Our enduring fascination with the occult gives the author's affirmation that witchcraft arises at times and in areas afflicted with social tensions a special quality of immediacy.
