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.

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.

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.

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.

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.

An edited collection of letters, chronicles, and sermons written, in the main, by clerics and other highly placed church officials during the eleventh and twelfth centuries. R.I. Moore uses them to analyse the beginning and development of popular heresy.
