This issue of the Library on Scientific Socialism includes the works of the outstanding figure of the Communist Party and the Soviet state F.E. Dzerzhinsky. They consider a number of important questions of scientific socialism: about the proletariat as a great revolutionary force capable of freeing all workers from economic and political oppression, about the Communist Party and its role in the struggle for the victory of socialism, about the nature of the new social system arising as a result of the socialist revolution, about the union of workers and peasants, as a necessary condition for the conquest of political power and the construction of socialism.
