Abstract
In the article, the author focused on the place occupied by the Turkic peoples in the Byzantine period, namely on the achievements that led the Turks to change the lives of the Byzantines. Their influence on the fall of the Byzantine state or the assimilation of peoples was more pronounced in comfort. At the same time, throughout its life - from the IV to the XV centuries - Byzantium was closely and variously connected with the civilizations of the East, telling about the reflection of the Turkic peoples in the Byzantine names and written texts of this period. Competition with the East developed in different ways. We have tried to comprehensively study all the surviving sources of the range of Byzantine, Muslim, Latin and Slavic languages. In the Western Byzantine region, Greek, Latin, South Slavic, Arabic and Turkish written sources are considered the most important. Although the aspect of Byzantine-Turkic interaction we have chosen is not systematically (unexplored) developed in science, its full-fledged study is widely factographically, etc.
