What term is used for the extreme left-wing workers' party in Russia during the revolution?

The term that refers to the extreme left-wing workers' party in Russia during the revolution is "Bolsheviks." This faction, led by figures such as Vladimir Lenin, played a crucial role in the October Revolution of 1917, which resulted in the overthrow of the provisional government and the establishment of a communist regime in Russia.

The Bolsheviks advocated for radical changes in society, including the establishment of a dictatorship of the proletariat, the abolition of private property, and the nationalization of industry. Their Marxist ideology was centered on the belief that the working class (or proletariat) would rise against the bourgeoisie (the capitalist class) in a revolution to create a classless society. This distinguishing focus on achieving a revolutionary change through force and organization set the Bolsheviks apart from other political movements of the time, such as various groups that favored more gradual reforms or moderation.

While "revolutionaries" may refer to broader categories of individuals or groups seeking change, and "socialists" encompasses a wider range of ideologies advocating for social ownership and democratic control of the means of production, the Bolsheviks were specifically identified as a prominent and radical faction advocating for immediate revolutionary action in the context of the Russian Revolution.
