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.

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.

This concise and balanced survey of heresy and inquisition in the Middle Ages examines the dynamic interplay between competing medieval notions of Christian observance, tracing the escalating confrontations between piety, reform, dissent, and Church authority between 1100 and 1500. Jennifer Kolpacoff Deane explores the diverse regional and cultural settings in which key disputes over scripture, sacraments, and spiritual hierarchies erupted, events increasingly shaped by new ecclesiastical ideas and inquisitorial procedures. Incorporating recent research and debates in the field, her analysis brings to life a compelling issue that profoundly influenced the medieval world.

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.

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.

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.

The followers of the martyred Bohemian priest Jan Hus (1371-1415) formed one of the greatest challenges to the medieval Latin Church. Branded as heretics, outlawed, then forced to fight for their faith as well as their lives, the Hussites occupy one of the most colorful and challenging chapters of European religious history. The essays reprinted in this book (along with one here first published in English and additional notes) explore the essence of the early Hussite movement by focusing on the nature and development of heresy both as accusation and identity. Heresy and Hussites in Late Medieval Europe first examines the definition of heresy, and its comparative nature across Europe. It investigates the unique practices of popular religion in local communities, while examining theology and its unavoidable conflicts. The repressive policy of crusade and the growth of martyrdom with its inevitable contribution to the formation of Hussite history is explored. The social application of religious ideas, its revolutionary outcomes, along with the intentional use of art in pedagogy and propaganda, situates the Czech heretics in the fifteenth century. An examination of leading personalities, together with the eventual and more formal church administration, rounds out the study of this remarkable era.

A fresh examination of the Cathar heresy, using the records of inquisitorial tribunals to bring out new details of life at the time.
