The Origin of the Family, Private Property and the State (1884), was a
provocative and profoundly influential critique of the Victorian nuclear
family. Engels argued that the traditional monogamous household was in
fact a recent construct, closely bound up with capitalist societies.
Under this patriarchal system, women were servants and, effectively,
prostitutes. Only Communism would herald the dawn of communal living and
a new sexual freedom and, in turn, the role of the state would become
superfluous.
