Trotskyism is the political ideology and branch of Marxism developed by Russian revolutionary Leon Trotsky and some other members of the Left Opposition and Fourth International. Trotsky described himself as an orthodox Marxist, a revolutionary Marxist, and a Bolshevik–Leninist as well as a follower of Marx, Engels, Vladimir Lenin, Karl Liebknecht, and 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 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 Joseph 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.
