Crusading and the Crusader States follows the progress of the major crusading expeditions, offers insights into their continuing failure, and charts the development of new attitudes towards Islam and its followers. This new edition takes into account the wealth of rich and varied recent research to demonstrate that crusading should be seen as central to the European experience in the Middle Ages, and engages in the key historiographical debates of the past decade. This includes new research on how crusades were formed, the political culture, networks, liturgies and crusading culture in the East. It is essential reading for all students of the Crusades and medieval history.
