The article deals with the features of sociological analysis of religion in Russia during the imperial period of its history. The national sociological tradition of study of religion as a socio-cultural phenomenon and a social institution, which was developed during this period, had its own unique and peculiar appearance and was just begun to revive again in post-Soviet Russia, is sharply different from the tradition that took place in the West. In this context, the appeal to the works of classics of Russian religious, socio-political thought, unfortunately undeservedly forgotten, is a very promising area of modern sociological research. When studying this issue, the author emphasizes the peculiarities of the historical development of Russian society and the state and the events that had a significant impact on the formation and development of scientific understanding of religion in Russia: reforms of Peter I, the elimination of patriarchy, the independence of the Russian Orthodox Church, its transformation into part of the bureaucratic state system created by Peter I, the beginning of a large-scale process of secularization of Russian society, the emergence of Westernism (the direction of the Russian social thought and political ideology focused on values of the Western European culture, which is negative to the idea of originality, an originality, uniqueness of ways of development of the Russian culture, combined with the aspiration of representatives of this trend to impose to the Russian nation of a form of the western culture, social practice and political system, rejecting the system of values and traditional foundations of activity of the Russian society), the imperial nature of the Russian statehood and official imperial ideology. The author analyzes the content of the Uvarov’s triad formula, which underlies the official imperial ideology, as well as the discussions that took place between representatives of Slavophilism and Westernism about understanding the historical path and fate of Russia, the historical role of Orthodoxy, the Russian Orthodox Church in the fate of the Russian people, Russian society and the state, as well as the whole world. In his opinion, this problem has remained relevant to the present, including in the framework of a sociological analysis of religion in post-Soviet Russia.
