Since its first appearance in 2004, The Crusades: A Reader has been the go-to sourcebook in the field. S.J. Allen and Emilie Amt cover the entire crusading movement, from its origins to its modern afterlife, using key primary source documents. The third edition features a new introduction that includes a guide for students on how to use the book. The editors have also added more content on women, material culture, Jewish and Byzantine perspectives, Muslim-Crusader interactions, and modern use of Crusade imagery and rhetoric by the Far Right. The geographic range is broad, covering not only Crusades in the Middle East, but also in Spain and in northern Europe and against European heretics. While scholarship, courses, and textbooks on the Crusades have proliferated over the past twenty years, The Crusades: A Reader remains the only comprehensive, up-to-date, and in-print sourcebook available on the subject.
