Abstract
The article analyzes the state of scientific development of relations between the Russian SFSR and the Ukrainian SSR in the 1920's in the Soviet scientific literature. The use of the problematic and chronological method allowed of to divide the historiography of the problem into groups, taking into account the key concepts, typical for the specified period of history, and to make its periodization. The scientific literature of the Soviet period is divided into two groups: the achievements of the direct participants of the state-building in the 1920's and the studies of Soviet historians and politicians. The works of the party and public officials in the 1920's are highlighted and it is proved that they influenced the formation of ideologemes in the historiography of Soviet Russian politics toward Ukraine in the 1920's. In their studies Soviet scientists tried to prove that the formation of a union state was the result of the initiative of the Soviet republics, the activity of the masses in the uniting movement was emphasized. The topic of social, political and economic relations between the republics, in particular between the Ukrainian SSR and the Russian SFSR was closed from the political point of view, and ignored by the Soviet historians.
It has been established that the study of the relations between the Russian SFSR and the Ukrainian SSR, conducted by the Soviet historians is characterized by the disadvantages in the schematic presentation of the material, subjectivity, limited use of the source base, the conclusions bias, ideologymania and myth-making. The Soviet historiography was put in the framework of compliance with the formula established in the totalitarian state. The role of the research center of fundamental historical topics was played by Moscow; the republican scientific institutions remained only small matters, devoid of national content
