History of the Communist Party of the Soviet Union (Bolsheviks)

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 revolutionary 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. The C. P. S. U.(B.) grew and gained strength in a fight over fundamental principles waged against the petty-bourgeois parties within the working-class movement-the Socialist-Revolutionaries (and earlier still, against their predecessors, the Narodniks), the Mensheviks, Anarchists and bourgeois nationalists of all shades-and, within the Party itself, against the Menshevik, opportunist trends-the Trotskyites, Bukharinites, nationalist deviators and other anti-Leninist groups. The C. P. S. U.(B.) gained strength and became tempered in the revolutionary struggle against all enemies of the working class and of all working people-against landlords, capitalists, kulaks, wreckers, spies, against all the hirelings of the surrounding capitalist states. The history of the C. P. S. U.(B.) is the history of three revolutions: the bourgeois-democratic revolution of 1905, the bourgeois-democratic revolution of February 1917, and the Socialist revolution of October 1917.
