The author deals with emergence of Stalinism as a phenomenon and elaboration of its principal, universal concepts. The new socio-political and legal doctrine was discussed and put into turnover by members of the Marxists-supporters of the statehood Society. Until recently virtually nothing has been known about activities of this entity. Due to use of unique archive materials (retrieved from the Academy of sciences archive and its Saint-Petersburg branch) the author succeeded in tracing genesis of principal ideological constructs of Stalinism. The author focuses on minutes and verbatim of presentations delivered by the Society’s members at the First All-Union congress of Marxists supporters of the statehood and at the First All-Union plenum of the Societies of Marxists-supporters of statehood societies.
