The purpose of this study is to analyze of Eurasianism, which began during the Russian scientific and philosophical emigration and has generated sharp discussion over the last century. Within the framework of Eurasianism, extensive research has been conducted on a wide range of interrelated topics, much of whose theoretical and practical significance is just beginning to be realized. The main objective of the article is the identification of various aspects of the national question, and its many issues which form the basis of Eurasian ethnosociology. Eurasianism has re-examined, among other issues, the inequality of national communities and the ways to eliminate this inequality, the conditions for fruitful interaction between ethnic groups, the nature of nationalism, and many more. Eurasianists have proposed a systemic and holistic approach to the national question, as an alternative to the prevailing ideas of today and, in the authors' opinion, an appropriate heuristic, especially given the deepening of many national problems in the modern world.
