Jonathan Harris continues to offer new insights in this, the third edition of a well-established classic. No student of the crusades or of relations between Byzantium and the West can afford to overlook this important study.

Byzantium and the Crusades is a compelling work regarding Byzantine interaction with the West, not as only a clash of cultures or as only series of plots, but as events also shaped by Byzantine ideology and foreign policy… I cannot recommend this book enough.

Harris' book offers a lucid, precise, and persuasively argued account of a pivotal era in the history of both Byzantium and the Crusades, and it will remain an indispensable reference for scholars and students for years to come.
