Conventional views assume a systematic intertwining between the Orthodox Church and the state, which makes Orthodox countries culturally hostile to modernity. These views have been shaped by a long history of antagonistic relationships between Western and Eastern European states and fail to grasp important long-term trends within the Orthodox religious landscape. The political culture in Orthodox countries has undergone several changes across the centuries. Under the East Roman (Byzantine) Empire, complementarity provided the blueprint for church-state relations. In later centuries, this model was modified to suit the Ottoman and Russian empires. Modernization also prompted Orthodox states to create state churches. Church-state separation was further pursued by communist and colonial regimes and was sometimes accompanied by the active persecution of clergy and the faithful. The political culture of modern Orthodox countries was decisively shaped by the nationalization of the faith, spurred by various national revivals. In the 19th century, Orthodox Christianity became a nationalized religion, whereby strong associations were established between newly constructed churches in Serbia, Bulgaria, Greece, and Romania and these countries' respective nations. This version of Orthodoxy was exported into the New World through communities of East European immigrants. The communist takeover of Eastern Europe further strengthened administrative fragmentation. After 1989–1990, the fragmentation of the USSR allowed for a more open expression of the model of national religion. Orthodoxy was revitalized but also served as a cornerstone for Russian, Ukrainian, and Estonian national identities, leading to regional ecclesiastical disputes. Current institutional dilemmas have resulted from these long-term processes.
