Trotskyism is a Marxist and Leninist political tradition associated with Leon Trotsky that developed in opposition to Stalin's consolidation of power in the Soviet Union. Its most distinctive theoretical concept is permanent revolution, which holds that in countries with delayed or uneven capitalist development, democratic and national liberation tasks can pass directly into socialist revolution rather than necessarily requiring a prolonged capitalist stage.
Trotsky also argued that socialist revolution has an international character and that a socialist revolution isolated within one country would face severe economic, political, and military pressures from the capitalist world. Trotskyism therefore combines Leninist revolutionary organisation with an emphasis on international proletarian revolution, criticism of bureaucratic degeneration, and opposition to the theory of socialism in one country. It became an international tendency through groups associated with Trotsky's Left Opposition and later Fourth International.
Trotsky's theory of permanent revolution originated in his analysis of the Russian Revolution and the contradictory conditions of economically backward countries. Trotsky argued that a capitalist class in a late developing country could be too weak or politically dependent to complete the democratic and national tasks historically associated with bourgeois revolutions. The working class could therefore become the leading political force in a democratic revolution and, after gaining power, move toward socialist measures.
The process was described as permanent because the revolution would pass continuously from democratic transformation toward socialist transformation rather than stopping at a separate bourgeois stage. Trotsky also extended the concept internationally, arguing that a socialist revolution beginning in one country would need to connect with revolutionary developments elsewhere if it were to overcome the pressures created by the international capitalist system.
Trotskyism emerged from the political conflict inside the Bolshevik Party and Soviet state during the 1920s. After Lenin's death, Trotsky opposed the growing influence of Stalin and criticised the increasing bureaucratisation of Soviet political institutions. The Left Opposition challenged aspects of economic policy, party democracy, and international strategy. Trotsky argued that the Soviet Union had become a degenerated workers state in which the revolutionary gains of the October Revolution remained but political power had become concentrated in a bureaucratic layer.
He did not therefore describe the Soviet Union simply as an ordinary capitalist state. His analysis attempted to explain how a state could retain nationalised property relations while political power was exercised by a bureaucratic apparatus rather than by democratic workers institutions. This became a central element of later Trotskyist theory.
Trotskyism's conception of the Soviet Union distinguished it from both liberal anti communist interpretations and Stalinist interpretations. Trotskyists argued that nationalised property and planned economic structures represented historical gains that should be defended while simultaneously opposing the bureaucratic political regime controlling them. Trotsky's analysis therefore created a difficult political position in which supporters defended the social foundations of the revolution while opposing the ruling bureaucracy.
Later Trotskyists disagreed about whether the Soviet Union and other states with similar structures should be classified as degenerated workers states, deformed workers states, state capitalist systems, or something else. These disagreements demonstrate that Trotskyism itself contains multiple schools and should not be treated as one perfectly uniform doctrine.
Trotskyism also places considerable emphasis on internationalism. Trotsky rejected Stalin's theory of socialism in one country as a sufficient strategic objective and argued that the international character of capitalism made international revolutionary expansion necessary for the long term survival and development of socialism. His reasoning was economic as well as political. National economies were increasingly integrated through trade, finance, technology, and production, while revolutionary states remained subject to external competition and internal contradictions.
Trotsky therefore viewed national revolution as part of a wider international process rather than as a self contained project. This did not mean that Trotskyists necessarily advocated military conquest of other countries. The theory centred on international class struggle and revolutionary political development rather than simply territorial expansion by an existing state.
Trotskyism retained important Leninist ideas about the revolutionary party, political organisation, and the working class. Trotsky did not reject disciplined revolutionary organisation; rather, he argued that communist parties had to remain politically accountable to revolutionary objectives and international working class movements. Trotskyist organisations subsequently developed theories of democratic centralism, revolutionary cadres, united fronts, transitional demands, and mass mobilisation.
The united front strategy sought temporary political cooperation among working class organisations against common reactionary or authoritarian threats without eliminating their independent political identities. Later Trotskyists also developed transitional programme approaches intended to connect immediate reforms with broader revolutionary objectives. These organisational and strategic concepts became important distinguishing features of international Trotskyist movements.
Trotskyism is often contrasted with Stalinism, but the distinction involves more than personal rivalry between Stalin and Trotsky. The two traditions disagreed over international revolution, Soviet political organisation, economic development, party democracy, bureaucratic power, and the appropriate interpretation of revolutionary strategy. Stalin's doctrine of socialism in one country argued that socialist construction could proceed within the Soviet Union even without immediate successful revolutions elsewhere.
Trotsky considered this approach strategically inadequate and maintained that international revolution was necessary for the complete development and defence of socialism. Trotsky also criticised the concentration of political power and repression under Stalin. Later Trotskyists consequently made opposition to Stalinism a central component of their political identity while retaining a commitment to Marxism and Leninism.
Trotskyism became an international political tradition after Trotsky's exile and especially after the establishment of the Fourth International in 1938. Trotskyist organisations appeared in numerous countries and interpreted local political conditions through the concepts of permanent revolution, internationalism, bureaucratic degeneration, and revolutionary working class organisation. They remained generally smaller than major communist parties but influenced intellectual debates, labour activism, anti colonial politics, student movements, and revolutionary organisations.
Internal divisions produced numerous Trotskyist tendencies with differing assessments of the Soviet Union, China, Cuba, social democracy, national liberation movements, and electoral politics. Consequently, contemporary Trotskyism is best understood as a family of related Marxist political traditions united around several central ideas rather than as one centrally controlled organisation.
