What defined the crusades in contrast to other wars was the opportunity for warriors to win a spiritual reward, the indulgence. In The Crusade Indulgence. Spiritual Rewards and the Theology of the Crusades, c. 1095-1216 Ane L. Bysted examines the theological and institutional development of the indulgence from the proclamation of the First Crusade to Pope Innocent III. This first comprehensive study of crusade indulgences in more than a hundred years challenges some earlier interpretations and demonstrates how theologians, popes, and crusade preachers in the 12th century formed the concept of indulgences and argued that fighting for Christ and the Church was meritorious in the sight of God and thus worthy of a spiritual reward proclaimed by the Church

A study of the Dominicans' and Franciscans' propagandist role in the thirteenth-century crusades.

Historian Pegg has produced a swift-moving, gripping narrative of a horrific crusade, drawing in part on thousands of testimonies collected by inquisitors in the years 1235 to 1245. These accounts of ordinary men and women bring the story vividly to life.

Throughout the history of the Crusades, liturgical prayer, masses, and alms were all marshaled in the fight against Muslim armies. In Invisible Weapons, M. Cecilia Gaposchkin focuses on the ways in which Latin Christians communicated their ideas and aspirations for crusade to God through liturgy, how public worship was deployed, and how prayers and masses absorbed the ideals and priorities of crusading. Placing religious texts and practices within the larger narrative of crusading, Gaposchkin offers a new understanding of a crucial facet in the culture of holy war.

Claiming that many in the West lack a thorough understanding of crusading, Jonathan Riley-Smith explains why and where the Crusades were fought, identifies their architects, and shows how deeply their language and imagery were embedded in popular Catholic thought and devotional life.

"The Popes and the Baltic Crusades" examines the formulation of papal policy on the crusades and missions in the Baltic region in the central Middle Ages and analyses why and how the crusade concept was extended from the Holy Land to the Baltic region.

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.
