The study calls the attention to the conclusion that Lenin's political and theoretical views on the first Russian revolution are organically and directly rooted in the historical-economical-theoretical and political analysis of the capitalist system, more precisely the Russian capitalism. From the perspective of his "preparation" for the revolution of 1905 (and 1917) it is such a fundamental circumstance that is necessary to understand his political-strategic considerations that later played a dominant role in his revolutionary activity and thinking.
