Jonathan Harris's classic text chronologically surveys Byzantine history in the time of the Crusades. The book reveals the attitudes of the Byzantine ruling elites towards the Crusades and their ultimate inability to adapt to the challenges this presented. Incorporating recent scholarship, this 3rd edition has 25 further images, as well as additional maps and genealogical tables. This new edition also comes with two significant additions to the text: Appendices that translate and analyse key primary sources and secondary texts.
