The Fourth International (FI) was a political international established in France in 1938 by Leon Trotsky and his supporters, having been expelled from the Soviet Union and the Communist International (also known as Comintern or the Third International).
In the Transitional Program, which was drafted in 1938 during the founding congress of the Fourth International, Trotsky reiterated the need for the legalization of the Soviet parties and worker's control of production.
Trotskyism (Russian: Троцкизм, Trotskizm) is the political ideology and branch of Marxism and Leninism developed by Russian revolutionary and intellectual Leon Trotsky along with some other members of the Left Opposition and the Fourth International. Trotsky described himself as an orthodox Marxist, a revolutionary Marxist, and a Bolshevik–Leninist as well as a follower of Karl Marx, Friedrich Engels, Vladimir Lenin, Karl Liebknecht, and Rosa Luxemburg. His relations with Lenin have been a source of intense historical debate. However, on balance, scholarly opinion among a range of prominent historians and political scientists such as E. H. Carr, Isaac Deutscher, Moshe Lewin, Ronald Suny, Richard B. Day and W. Bruce Lincoln was that Lenin's desired "heir" would have been a collective responsibility in which Trotsky was placed in "an important role and within which Stalin would be dramatically demoted (if not removed)".
Trotsky advocated for a decentralized form of economic planning, workers' control of production, elected representation of Soviet socialist parties, mass soviet democratization,the tactic of a united front against far-right parties,cultural autonomy for artistic movements, voluntary collectivisation, a transitional program, and socialist internationalism. He supported founding a vanguard party of the proletariat, and a dictatorship of the proletariat (as opposed to the "dictatorship of the bourgeoisie", which Marxists argue is a major component of capitalism) based on working-class self-emancipation and council democracy. Trotsky also adhered to scientific socialism and viewed this as a conscious expression of historical processes. Trotskyists are critical of Stalinism as they oppose Stalin's theory of socialism in one country in favour of Trotsky's theory of permanent revolution. Trotskyists criticize the bureaucracy and anti-democratic current developed in the Soviet Union under Stalin.
World communism, also known as global communism or international communism, is a form of communism placing emphasis on an international scope rather than being individual communist states. The long-term goal of world communism is an unlimited worldwide communist society that is classless, moneyless, stateless, and nonviolent, which may be achieved through an intermediate-term goal of either a voluntary association of sovereign states as a global alliance, or a world government as a single worldwide state.
A series of internationals have proposed world communism as a primary goal, including the First International, the Second International, the Third International (the Communist International or Comintern), the Fourth International, the Revolutionary Internationalist Movement, Maoist Internationalist Movement, the World Socialist Movement, and variant offshoots. The methods and political theories of each International remain distinct in their pursuit of the global communist society.
The Transitional Program, originally titled The Death Agony of Capitalism and the Tasks of the Fourth International and later reprinted under the title, The Transitional Program and the Struggle for Socialism, is a political platform adopted by the 1938 founding congress of the Fourth International, the international Leninist organization founded by Leon Trotsky. It is an example of a transitional programme.
