Knightly Piety refers to a specific strand of Christian belief espoused by
knights during the Middle Ages. The term comes from
Ritterfrömmigkeit coined by Adolf Waas in his book
Geschichte der Kreuzzüge. Many scholars debate the importance of knightly piety, however it is apparent as an important part of the
chivalric ethos based on its appearance within the Geoffroi de Charny's
Book of Chivalry as well as much of the popular literature of the time.
