The author, relying on the concept of nations as imagined communities, sharing the existence of the scientific concepts of “ethnic” and “civil” nations, considers the possibility of the emergence of a single national myth, which could become the most important construct in the formation of national unity in a multinational country. Based on various legislative initiatives, amendments to the Constitution of Russia, considering certain aspects of historical policy in Russia, the author concludes that after 2014, on the background of the Ukrainian crisis, the Syrian crisis, US and European Union’s sanctions pressure and political confrontation with the West, the Russian authorities situationally started the mobilisation of public opinion. This policy is capable of producing results only in the short term. Achievement of national unity based on the single national myth, acceptable to most of the Russian society, will require more thorough work and delicate inclusion in the information space, as well as in the educational programs of secondary and higher education.
