Stalinism
Stalinism is a term largely used by anti-communists, revisionists and Trotskyists to attack real or imagined supporters of the socialist construction which took place in the Union of Soviet Socialists Republics and the Bolshevik Party under Joseph Stalin.
Despite the rampant usage of the term in bourgeois academia, "Stalinism" was seldom used in the Soviet Union and other socialist countries.
Marxist–Leninist usage
Certain Marxist–Leninists use the term "Stalinism" as a self-description, viewing it as a point of pride to be associated with Stalin in such a way. Albanian communist leader Enver Hoxha sometimes used the term "Stalinism" or "Marxism–Leninism–Stalinism" to contrast himself with the anti-Stalinist Khrushchev clique and other phony "Marxist–Leninists".
