Stalinism is the means of governing and related policies implemented by Joseph Stalin. Stalinist policies in the Soviet Union included: state terror, rapid industrialization, the theory of socialism in one country, a centralized state, collectivization of agriculture, cult of personality, and subordination of interests of foreign communist parties to those of the Communist Party of the Soviet Union—deemed by Stalinism to be the most forefront vanguard party of communist revolution at the time. Stalinism promoted the escalation of class conflict, utilizing state violence to forcibly purge society of claimed supporters of the bourgeoisie, regarding them as threats to the pursuit of the communist revolution that resulted in substantial political violence and persecution of such people. These included not only bourgeois people but also working-class people accused of counter-revolutionary sympathies.
