Nathan Websdale ‘DEFENDING TWO CRADLES OF CHRISTIANITY:’ THE AGENCY OF PHILARETOS BRAAKHAMIOS AND THE POST-MANZIKERT CONTEST FOR ANTIOCH AND EDESSA. In the fallout of the Battle of Manzikert and the resulting Byzantine civil war of 1071-72, the dissolving fabric of eastern Byzantium enabled the construction of several smaller polities based upon ethnic, cultural, and linguistic grounds and by the force of sheer ambition. One such of these was the proto-principality of Antioch and Edessa ruled by the Chalcedonian-Armenian general Philaretos Braakhamios. Much maligned by both modern historians and of the eleventh and twelfth centuries, the last Eastern Christian ruler of Antioch before its fall to the Seljuk Turks and the Crusaders was the archetype for both Cilician Armenia and the Principality of Antioch. His fascinating career sought to safeguard and unite the Armenian people against the Turkish invasions despite the divisions of their Apostolic faith. Moreover, in the collapse of Byzantine organisation across Anatolia, Philaretos’ career is notable for its longevity and the factors that enabled this. For fifteen years until c.1085, Philaretos blended the court cultures of Armenia, Byzantium and the Arabic world while leading armies to the delivery of Edessa, the massacre of the exiled princes of Greater Armenia, and against the brother of the nascent Alexios Komnenos before Philaretos’ own ultimate apostasy to Islam. The complex relationship between Alexios and Philaretos is the focus of this paper, the first produced in English in forty years as we discuss that what has been previously dismissed as a turbulent and ‘nominal’ vassal relationship between the two developed into a working partnership and a dynamic use of traditional Byzantine deputation.
