Armenians in the Byzantine Empire is a new study exploring the relationship between the Armenians and Byzantines from the ninth through eleventh centuries. Utilising primary sources from multiple traditions, the evidence is clear that until the eleventh century Armenian migrants were able to fully assimilate into the Empire, in time recognized fully as Romaioi (Byzantine Romans). From the turn of the eleventh century however, migrating groups of Armenians seem to have resisted the previously successful process of assimilation, holding onto their ancestral and religious identity, and viewing the Byzantines with suspicion. This stagnation and ultimate failure to assimilate Armenian migrants into Byzantium has never been thoroughly investigated, despite its dire consequences in the late eleventh century when the Empire faced its most severe crisis since the rise of Islam, the arrival and settlement of the Turkic peoples in Anatolia.

The successful coexistence of different ethnic, linguistic, and religious groups within the same political boundaries depends in part on the resolution of the tension between uniformity and separateness. This volume reviews sources of tension and their resolution in a number of cases that may be considered paradigmatic and which include nomads and Muslims, the Serbs, the Armenians, and the population of Byzantine Italy. The mechanisms of integration or acculturation and their various degrees of success are investigated - as are the responses of different groups - in an effort to present some of the complexities of this society, rich in its diversity and impressive in its unicity.
