What groups would most likely support the Bolsheviks?

The Bolsheviks were primarily supported by the working class, particularly industrial workers and peasants who sought radical change during the tumultuous period of the Russian Revolution. Additionally, they gained backing from soldiers disillusioned by World War I and leftist intellectuals who advocated for a Marxist ideology. Other groups, such as the urban poor and some segments of the intelligentsia, also aligned with the Bolsheviks due to their promises of land redistribution and social justice.
