 After Lenin's death, Stalin's administration established an ideology known as Marxism–Leninism, a movement that came to be interpreted differently by various contending factions in the communist movement.After being forced into exile by Stalin's administration, Trotsky argued that Stalinism was a debasement of Leninism, which was dominated by bureaucratism and Stalin's own personal dictatorship.Marxism–Leninism was adapted to many of the 20th century's most prominent revolutionary movements, forming into variants such as Stalinism, Maoism, Juche, Ho Chi Minh Thought, and Castroism.
