"The Communist Party of the Soviet Union (Bolsheviks)" has traversed a long and glorious road, leading from the first tiny Marxist circles and groups that appeared in Russia in the eighties of the past century to the great Party of the Bolsheviks, which now directs the first Socialist State of Workers and Peasants in the world. The C.P.S.U.(B.) grew up on the basis of the working-class movement in pre-revolutionary Russia; it sprang from the Marxist circles and groups which had established connection with the working-class movement and imparted to it a Socialist consciousness. The C.P.S.U.(B.) has always been guided by the revolutionery teachings of Marxism-Leninism. In the new conditions of the era of imperialism, imperialist wars and proletarian revolutions, its leaders further developed the teachings of Marx and Engels and raised them to a new level.
