Trotskyism is the political ideology and branch of Marxism 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, Frederick 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 ".
The Communist International (Comintern), also known as the Third International, was an international organization founded in 1919 that advocated world communism, and which was led and controlled by the Communist Party of the Soviet Union.

The Comintern was preceded by the dissolution of the Second International in 1916. Vladimir Lenin, Leon Trotsky, and Joseph Stalin were all honorary presidents of the Communist International.

The Second International continued the work of the dissolved First International, though excluding the powerful anarcho-syndicalist movement.
