The dictatorship of the proletariat is a term employed by Karl Marx in his 1875 Critique of the Gotha Program that refers to a transition period between capitalist and communist society "in which the state can be nothing but the revolutionary dictatorship of the proletariat". The term refers to a concentration of power in which rule by the proletariat (working class) would supplant the current political situation controlled by the bourgeoisie (propertied class). It does not refer to the repressive situation associated with the contemporary meaning of the term "dictatorship."
Before 1875, Marx said little about what in practice would characterize a “dictatorship of the proletariat,” believing that planning in advance the details of a future socialist system constituted the fallacy of "utopian socialism." Thus, Marx used the term very infrequently.
