In medieval Europe hostages were given, not taken. They were a means of guarantee used to secure transactions ranging from treaties to wartime commitments to financial transactions. In principle, the force of the guarantee lay in the threat to the life of the hostage if the agreement were broken but, while violation of agreements was common, execution of hostages was a rarity. Medieval hostages are thus best understood not as simple pledges, but as a political institution characteristic of the medieval millennium, embedded in its changing historical contexts. In the Early Middle Ages, hostageship was principally seen in warfare and diplomacy, operating within structures of kinship and practices of alliance characteristic of elite political society. From the eleventh century, hostageship diversified, despite the spread of a legal and financial culture that would seem to have made it superfluous. Hostages in the Middle Ages traces the development of this institution from Late Antiquity through the period of the Hundred Years War, across Europe and the Mediterranean World. It explores the logic of agreements, the identity of hostages, and the conditions of their confinement, while shedding light on a wide range of subjects, from sieges and treaties, to captivity and ransom, to the Peace of God and the Crusades, to the rise of towns and representation, to political communication and shifting gender dynamics. The book closes by examining the reasons for the decline of hostageship in the Early Modern era, and the rise the modern variety of hostageship that was addressed by the Nuremberg tribunals and the United Nations in the twentieth century.

This study examines the role of written agreements in eleventh- and twelfth-century Catalonia, and how they determined the social and political order. By tracing the fate of these agreements - or convenientiae - from their first appearance to the late twelfth century, it is possible to demonstrate the remarkable stability of the fluid structures which they engendered in what is generally thought of as 'feudal society'. The process of documentary change reveals the true nature and pace of the 'transformation of the year 1000'. Analysis of the convenientia as an instrument of power and its interaction with oral practices contributes to a deeper understanding of the role of the written word in medieval societies. Finally, a broad historiographical context establishes the significance of this study of Catalonia for a more general appreciation of the medieval Mediterranean world.

Taking their inspiration from the work of Thomas N. Bisson, to whom the book is dedicated, the contributors to this volume explore the experience of power in medieval Europe: the experience of those who held power, those who helped them wield it, and those who felt its effects. The seventeen essays in the collection, which range geographically from England in the north to Castile in the south, and chronologically from the tenth century to the fourteenth, address a series of specific topics in institutional, social, religious, cultural, and intellectual history. Taken together, they present three distinct ways of discussing power in a medieval historical context: uses of power, relations of power, and discourses of power. The collection thus examines not only the operational and social aspects of power, but also power as a contested category within the medieval world. The Experience of Power suggests new and fruitful ways of understanding and studying power in the Middle Ages.
