First full-length study of Pope Gregory X in relation to Crusade, demonstrating his significant impact.

Pope Gregory X stood at the very centre of the crusading movement in the later thirteenth century. An able diplomat, he showed himself adept at navigating the political waters of Europe and the Mediterranean World. His crusade gained the participation of virtually all of the leaders of Western Europe, and even the Byzantine emperor and the Ilkhan of the Mongols: crucial if his crusade were to have a chance of defeating the very formidable and successful Mamluk Sultan Baybars. However, Gregory's premature death put paid to his crusade plans. Perhaps because of this, Gregory has hitherto been somewhat neglected by historians - a gap which this book aims to fill. It provides a full account of his contribution to the Crusade, demonstrating that he left a lasting mark on how crusading would operate in the years to come. Philip Baldwin received his doctorate from Queen Mary, University of London.

In December 1235, Pope Gregory IX altered the mission of a crusade he had begun to preach the year before. Instead of calling for Christian magnates to go on to fight the infidel in Jerusalem, he now urged them to combat the spread of Christian heresy in Latin Greece and to defend the Latin empire of Constantinople. The Barons' Crusade, as it was named by a fourteenth-century chronicler impressed by the great number of barons who participated, would last until 1241 and would represent in many ways the high point of papal efforts to make crusading a universal Christian undertaking. This book, the first full-length treatment of the Barons' Crusade, examines the call for holy war and its consequences in Hungary, France, England, Constantinople, and the Holy Land. In the end, Michael Lower reveals, the pope's call for unified action resulted in a range of locally determined initiatives and accommodations. In some places in Europe, the crusade unleashed violence against Jews that the pope had not sought; in others, it unleashed no violence at all. In the Levant, it even ended in peaceful negotiation between Christian and Muslim forces. Virtually everywhere, but in different ways, it altered the relations between Christians and non-Christians. By emphasizing comparative local history, The Barons' Crusade: A Call to Arms and Its Consequences brings into question the idea that crusading embodies the religious unity of medieval society and demonstrates how thoroughly crusading had been affected by the new strategic and political demands of the papacy.

In 1213, Pope Innocent III issued his letter Vineam Domini, thundering against the enemies of Christendom—the "beasts of many kinds that are attempting to destroy the vineyard of the Lord of Sabaoth"—and announcing a General Council of the Latin Church as redress. The Fourth Lateran Council, which convened in 1215, was unprecedented in its scope and impact, and it called for the Fifth Crusade as what its participants hoped would be the final defense of Christendom. For the first time, a collection of extensively annotated and translated documents illustrates the transformation of the crusade movement. Crusade and Christendom explores the way in which the crusade was used to define and extend the intellectual, religious, and political boundaries of Latin Christendom. It also illustrates how the very concept of the crusade was shaped by the urge to define and reform communities of practice and belief within Latin Christendom and by Latin Christendom's relationship with other communities, including dissenting political powers and heretical groups, the Moors in Spain, the Mongols, and eastern Christians. The relationship of the crusade to reform and missionary movements is also explored, as is its impact on individual lives and devotion. The selection of documents and bibliography incorporates and brings to life recent developments in crusade scholarship concerning military logistics and travel in the medieval period, popular and elite participation, the role of women, liturgy and preaching, and the impact of the crusade on western society and its relationship with other cultures and religions. Intended for the undergraduate yet also invaluable for teachers and scholars, this book illustrates how the crusades became crucial for defining and promoting the very concept and boundaries of Latin Christendom. It provides translations of and commentaries on key original sources and up-to-date bibliographic materials.
