We want to explore what phenomena (and not events) of the historical past correspond to the Russian fairy tale and to what extent it really determines and causes it. In other words, our goal is to find out the sources of the fairy tale in historical reality. The study of the genesis of a phenomenon is not yet the study of the history of this phenomenon. The study of history cannot be carried out immediately - this is a matter of long years, it is not a matter of one person, it is a matter of generations, a matter of Marxist folklore emerging in our country. Studying genesis is the first step in this direction. This is the main question posed in this work.
