"This series of informative essays embodies new methodologies and details many aspects of Christian-Muslim tensions and conflicts over eight centuries, emphasizing the Syrian and Anatolian borders and excluding the other major areas of conflict between these two missionary empires. [...] Recommended.--S. Bowman, emeritus, University of Cincinnati ""CHOICE, January 2024"" This important volume challenges us to rethink how we understand the frontier, both culturally and geographically, between the Byzantine and Islamic worlds from the 7th century CE onwards. Its eleven chapters present cutting-edge research and establish a new baseline from which this key region must now be studied. --John F. Haldon, Princeton University"
