This study by Simonia is among the first to present an in-depth analysis of the theory and practical effect of the transition to socialism in Russia. The work consists of two parts: the first deals with the attempt initiated by Lenin to affect a socialist system, the evolution of his theoretical thought, and his search for a model of indirect transition to socialism (through state capitalism); the second analyzes Stalin's direct declaration of state-bureaucratic socialism, his distortion of the ideas of cooperation, state capitalism, and socialist accumulation, and the failure of his communist society. In concluding, Simonia relates Russia's socialist development to its current economic and socio-political problems, providing insights into its tortuous and thorny history.
