Marxism and the Oppression of Women: Toward a Unitary Theory (1983; revised edition 2013) is a book by the sociologist Lise Vogel that is considered an important contribution to Marxist Feminism. Vogel surveys Karl Marx and Friedrich Engels's comments on the causes of women's oppression, examines how socialist movements in Europe and in the United States have addressed women's oppression, and argues that women's oppression should be understood in terms of women's role in social reproduction and in particular in reproducing labor power.
