A proletarian dictatorship is a political system in which the working class, or proletariat, holds power and controls the state apparatus to suppress the bourgeoisie and enact socialist reforms. This concept is central to Marxist theory, which views the proletarian dictatorship as a necessary transitional phase toward achieving a classless society. The establishment of such a system is often marked by the use of revolutionary violence and significant changes to existing social and economic structures.
