Marxist attempts at integrating gender in the class-struggle framework was uneven in the Russian revolutionary movement. A class reductionism often held back the Bolsheviks, but contests with the liberal feminists, as well as the objective reality of more women entering the labour force, led to changes. Women activists took the lead in this. The Revolution of 1917 saw a much greater degree of women’s involvement. Women workers provided leadership in the early stages of the February Revolution, though it often remains unacknowledged by mainstream (including mainstream left) historiography of the revolution. At the same time, gendering the practice of class went hand in hand with a sharp rise in class issues against undifferentiated feminism, for liberal feminism supported the war and the bourgeois Provisional Government.
