The subject of the study is the modern transformation of political identity in the Middle Eastern states and communities that profess Islam. The author examines in detail the complex of identifications that exist in the Middle East region. Particular attention is paid to the interaction and harmonization of religious, imperial, national and ethno-cultural identities. Regional features of identification transformations are considered both in the context of transformations in the global system of international relations, and taking into account the regional specifics of political processes and the general originality of the socio-cultural space. The general tendencies typical for all communities of the region under consideration are analyzed, as well as particular features of identity transformations as a factor of state policy on the example of Turkey and Iran. The novelty of the study lies in the analysis of transnational identification transformations in the Middle East region in the context of global trends towards the growing role of transnational identity in international relations and world politics. The author's special contribution to the study of the topic is the combination of fundamental theoretical approaches to the study of identity with the methodology of system analysis, which allows to more accurately describe the complex multi-level structure of modern identities, based on the current works of Russian, Western and Middle Eastern researchers. The main results of the study are the determination of general and particular features of identification transformations in the Middle East region, as well as the definition of the functions of religious and imperial identities in the system of identifications.
