Two-stage theory

The two-stage theory, or stagism, is a Marxist–Leninist political theory which argues that underdeveloped countries such as Tsarist Russia must first pass through a stage of capitalism via a bourgeois revolution before moving to a socialist stage.

Stagism was applied to countries worldwide that had not passed through the capitalist stage. In the Soviet Union, the two-stage theory was opposed by the Trotskyist theory of permanent revolution.

While the discussion on stagism focuses on the Russian Revolution, Maoist theories such as New Democracy tend to apply a two-stage theory to struggles elsewhere.
