The roles of popes, saints, and crusaders were inextricably intertwined in the Middle Ages: papal administration was fundamental in the making and promulgating of new saints and in financing crusades, while crusaders used saints as propaganda to back up the authority of popes, and even occasionally ended up being sanctified themselves. Yet, current scholarship rarely treats these three components of medieval faith together. This book remedies that by bringing together scholars to consider the links among the three and the ways that understanding them can help us build a more complete picture of the working of the church and Christianity in the Middle Ages.
