The interdict was an important and frequent event in medieval society. It was an ecclesiastical sanction which had the effect of closing churches and suspending religious services. Often imposed on an entire community because its leaders had violated the rights and laws of the Church, popes exploited it as a political weapon in their conflicts with secular rulers during the thirteenth century. In this book, Peter Clarke examines this significant but neglected subject, presenting a wealth of new evidence drawn from manuscripts and archival sources. He begins by exploring the basic legal and moral problem raised by the interdict: how could a sanction that punished many for the sins of the few be justified? From the twelfth-century, jurists and theologians argued that those who consented to the crimes of others shared in the responsibility and punishment for them. Hence important questions are raised about medieval ideas of community, especially about the relationship between its head and members.
The book goes on to explore how the interdict was meant to work according to the medieval canonists, and how it actually worked in practice. In particular it examines princely and popular reactions to interdicts and how these encouraged the papacy to reform the sanction in order to make it more effective. Evidence including detailed case-studies of the interdict in action, is drawn from across thirteenth-century Europe--a time when the papacy's legislative activity and interference in the affairs of secular rulers were at their height.

Alexander III was one of the most important popes of the Middle Ages and his papacy (1159-81) marked a significant watershed in the history of the Western Church and society. This book provides a long overdue reassessment of his papacy and his achievements, bringing together thirteen essays which review existing scholarship and present the latest research and new perspectives. Individual chapters cover topics such as Alexander's many contributions to the law of the Church, which had a major impact upon Western society, notably on marriage, his relations with Byzantium, and the extension of papal authority at the peripheries of the West, in Spain, Northern Europe and the Holy Land. But dominant are the major clashes between secular and spiritual authority: the confrontation between Henry II of England and Thomas Becket after which Alexander eventually secured the king's co-operation and the pope's eighteen-year conflict with the German emperor, Frederick I. Both the papacy and the Western Church emerged as stronger institutions from this struggle, largely owing to Alexander's leadership and resilience: he truly mastered the art of survival.
