The system of interrelations between the center and the regions in the Soviet Union from the 1920s to the early 1930s is analyzed in the study. Concrete cases are used to describe the development of relations and mutual interactions between the center and the regions in the USSR as well as the factors determining them. The tools used and the attempts made by the center, where the decisive power was concentrating in J. V. Stalin's hands, to centralize state power and limit the influence of Party elite at the regional level are explained. The latter had, however, strong positions in the Central Committee of the Bolshevist Party and were able to enforce the interests of their particular regions, and thus protect and strengthen their own positions within the Party system. It appears that not only geographical factors and insufficient control of the provinces played some role in the development of interrelations between the center and the regions; of great importance was also the ethnic policy and later also, in particular, the start of radical modernization of the country by means of forced collectivization and industrialization. Both of these processes strengthened dramatically Moscow's centralization efforts; on the other hand, however, they created new opportunities for the regional elite to increase their influence and strengthen their positions.
