The collection includes the fundamental works of K. Marx, F. Engels and V.I. Lenin, giving an idea not only of the essence of the Marxist concept, but also of its dynamics. The work “Anti-Dühring” by F. Engels was written in defense of Marxist theory from the attacks of the petty-bourgeois ideologist E. Dühring, and is still an indispensable tool for mastering the Marxist worldview, ideological weapons of the working people in the struggle against bourgeois ideology. In the “Manifesto of the Communist Party,” K. Marx and F. Engels extremely simply and convincingly substantiated the goals, objectives and most effective methods of struggle of the barely nascent world communist movement against the old world order. Selected works of V.I. Lenin, as the only world-class theorist among Russian Marxists, characterizes the essence of Marxism and its significance as a single international teaching.
