The author analyzes the ideological views of a group of Russian migrants of the first wave, known as Eurasianists, including N.S. Trubetskoy, P.N. Savitsky, N.N. Alekseeva, L.N. Karsavina and others. The author discusses fundamental elements of the classical Eurasianist program, such as the role of the Orthodox Church and the state in the life of Russia and its society, their attitude to Roman Catholic culture, and their place in dialogue with other religions. In addition, other important elements of Eurasianism noted here are the ideas of pan-Eurasian nationalism, ideocracy, the spatial borders of Russia-Eurasia, the symphonic personality, a guarantee state. These issues are associated directly with the authors of these concepts and with Eurasianism in general. The author demonstrates the continuity with the teachings of the Slavophiles and highlights the special attention that the Eurasians paid to the traditional cultures of Russia. Also noted is the interest in Eurasianism of church circles in exile in Europe. At the same time, the Eurasianists' critical vies on the "Petersburg period" in the history of the Russian church are highlighted, which are also implicit in Eurasianism as an independent ideological and philosophical line of thought of Russian emigration in the first half of the twentieth century. An attempt is made to show how, through conservative thought, Eurasians tried to form a new type of political identity. This ideological direction with an emphasis on spirituality and special institutions was considered by Eurasians as a prototype of the future statehood of Russia as opposed to the Soviet-Marxist system. In the context of the contemporary Eurasian integration (EAEU), of the current role of the Russian Orthodox Church and external political manipulations around the role of the Moscow Patriarchate, the theoretical views of the Eurasians take on a new dimension.
