Trotskyism is the political ideology and branch of Marxism developed by Russian revolutionary Leon Trotsky and by some other members of the Left Opposition and Fourth International. Trotsky self-identified as an orthodox Marxist, a revolutionary Marxist, and Bolshevik–Leninist, a follower of Marx, Engels, and of 3L: Vladimir Lenin, Karl Liebknecht, Rosa Luxemburg. He supported founding a vanguard party of the proletariat, proletarian internationalism, and a dictatorship of the proletariat based on working class self-emancipation and mass democracy. Trotskyists are critical of Stalinism as they oppose Joseph Stalin's theory of socialism in one country in favor of Trotsky's theory of permanent revolution. Trotskyists also criticize the bureaucracy and anti-democratic current that developed in the Soviet Union under Stalin.
Shachtmanism is the form of Marxism associated with Max Shachtman (1904–1972). It has two major components: a bureaucratic collectivist analysis of the Soviet Union and a third camp approach to world politics. Shachtmanites believe that the Stalinist rulers of proclaimed socialist countries are a new ruling class distinct from the workers and reject Trotsky's description of Stalinist Russia as a "degenerated workers' state".

The International Socialist Organization (ISO) was a Trotskyist group active primarily on college campuses in the United States that was founded in 1976 and dissolved in 2019. The organization held Leninist positions on imperialism and the role of a vanguard party. However, it did not believe that necessary conditions for a revolutionary party in the United States were met; ISO believed that it was preparing the ground for such a party. The organization held a Trotskyist critique of nominally socialist states, which it considered class societies. In contrast, the organization advocated the tradition of "socialism from below." as articulated by Hal Draper. Initially founded as a section of the International Socialist Tendency (IST), it was strongly influenced by the perspectives of Draper and Tony Cliff of the British Socialist Workers Party. It broke from the IST in 2001, but continued to exist as an independent organization for the next eighteen years. The organization advocated independence from the U.S. two-party system and sometimes supported electoral strategies by outside parties, especially the Green Party of the United States.
