"The byzantine army in VIII - XI centuries: organizational structure, command of the armed forces, every-day life. The project was connected with investigations of the several problems of the development military-administration system of the Byzantine Empire in 8 th – 11th centuries. In the course of project were in-vestigate two closely related problems of the history of Byzantium during the reign of the Macedonian dynasty. At the first, the transformation of military-organizational structure of the empire from provincial militia to the standing army. Secondly, the polemical notions characteristic of the traditional Byzantine society of the given time were investigated. In the 10th – first half of the 11th century the Byzantine army was a complex, dynamically developing structure. In this period, Byzantium was the only Christian state with a clearly articulated military doctrine. Despite the preservation of traditional social structures, the purposeful military policy of the emperors of the Macedonian dynasty allowed the creation, by the end of the 10th century, capable regular army. This allowed Byzantium to retain its military-political power until the second half of the 11th century.
