The first comprehensive analysis of the dynamic interpenetration of religion and war in the West from C4 to early C13.Warfare in all histories and cultures shows evidence of the driving need to sanctify the cause, from the personal devotions of individuals to the grand designs of the architects of battle. In his important study David Bachrach takes a first thorough look at warfare in western Europe and its interaction with Christianity, from the initial appearance of the pacifist sect to the medieval popes' certainty of the crusades as "holy war".Religion played a necessary and crucial role in the conduct of war during late Antiquity and the middle ages. Military discipline and morale depended in significant part on religious rites carried out by priests and soldiers in the field and by their supporters on the home front. Just as importantly, warfare in the late Roman empire and its western successor states had a profound impact on Christian religious practice and doctrine: liturgical developments - in prayer, communion, confession, penance - can be linked to the military needs of the Christian Roman world and the Christian states of medieval Europe. Even more profound was the transformation of Christianity itself from pacifism to a faith which justified and eventually glorified killing on behalf of the Church.This volume provides the first comprehensive analysis of the dynamic interpenetration of religion and war in the West during almost a thousand years, fromthe accession of Constantine the Great in the early fourth century until the eve of the Fourth Lateran Council in the early thirteenth. With its often new interpretations of a vast array of sources, Religion and the Conduct ofWar has much to say to historians and others on the nature of war and its relationship with faith. DAVID S. BACHRACH is Associate Professor of History, University of New Hampshire.
