Formation and evolution of the Party Ideology of the Russian Social Democrats/Bolsheviks as the basis of the future state ideology of the Country of Soviets

The subject of this study is the process of formation of the party ideology of the RSDLP from the moment of its institutionalization at the end of the XIX century until the seizure of power by the Bolsheviks in October 1917. The subject of the study is those aspects of the Bolshevik worldview that later formed the basis of the ideology of the Soviet state. Special attention is paid to Lenin's understanding of ideology as a class worldview of the proletariat, proposed by the "vanguard" of this class - the Russian Social Democratic Workers' Party. The author pays great attention to the class attitudes of the leader of the Russian Social Democrats, V. I. Lenin, because they had a key impact on the formation of the Bolshevik ideology. The novelty of the research lies in the author's approach, which combines the principles of historicism and scientific objectivity with a class understanding of the essence of ideology, on which the development of the party ideology of the RSDLP was based. This allows us to analyze the logic of V. I. Lenin's theoretical constructions, to understand his personal worldview,. which, due to the authority of the party leader, was transformed, first into a party ideology, and then into a state one. The author comes to the following conclusions: the class approach predetermined the basic principles of the formation of the ideology of the Russian Social Democrats/Bolsheviks. Perceiving the class worldview as a kind of monolith based on the relation of property to the means of production, the party leader developed a coherent picture of the world, which changed only when political conditions transformed: when the socialist revolution seemed to be a matter of an uncertain future, and when, in the conditions of the world war, its implementation became temporally tangible. It was the presence of a clearly defined ideology, which was shared by the majority of the Bolsheviks, that allowed them to take power into their own hands during the revolution.
