The Bolsheviks, led by Vladimir Lenin, were a far-left faction of the Marxist Russian Social Democratic Labour Party (RSDLP) which split with the Mensheviks at the Second Party Congress in 1903. The Bolshevik party, formally established in 1912, seized power in Russia in the October Revolution of 1917, and was later renamed the Russian Communist Party, All-Union Communist Party, and Communist Party of the Soviet Union. The party's ideology, based on Leninist and later Marxist–Leninist principles, is known as Bolshevism.
Lev Davidovich Bronstein, better known as "Leon Trotsky", was a Russian revolutionary, politician, and political theorist. He was a central figure in the 1905 Revolution, October Revolution, Russian Civil War, and establishment of the Soviet Union. Trotsky, Vladimir Lenin, and Joseph Stalin were widely considered the three most prominent Soviet figures, and Trotsky was "de facto" second-in-command during the early years of the Russian Soviet Republic. Ideologically a Marxist and Leninist, his thought and writings inspired a school of Marxism known as Trotskyism.
Nikolai Ivanovich Bukharin was a Russian revolutionary, Soviet politician, and Marxist theorist. A prominent Bolshevik described by Vladimir Lenin as a "most valuable and major theorist" of the Communist Party, Bukharin was active in the Soviet leadership from 1917 to his purge in the 1930s.
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 ten years 1917–1927 saw a radical transformation of the Russian Empire into a socialist state, the Soviet Union. Soviet Russia covers 1917–1922 and Soviet Union covers the years 1922 to 1991. After the Russian Civil War (1917–1923), the Bolsheviks took control. They were dedicated to a version of Marxism developed by Vladimir Lenin. It promised the workers would rise, destroy capitalism, and create a socialist society under the leadership of the Communist Party of the Soviet Union. The awkward problem, regarding Marxist revolutionary theory, was the small proletariat, in an overwhelmingly peasant society with limited industry and a very small middle class. Following the February Revolution in 1917 that deposed Nicholas II of Russia, a short-lived provisional government gave way to Bolsheviks in the October Revolution. The Bolshevik Party was renamed the Russian Communist Party (RCP).
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 resolved at its Second Congress in 1920 to "struggle by all available means, including armed force, for the overthrow of the international bourgeoisie and the creation of an international soviet republic as a transition stage to the complete abolition of the state". The Comintern was preceded by the dissolution of the Second International in 1916. Vladimir Lenin, Leon Trotsky, and Joseph Stalin were both honorary presidents of the Communist International.

The history of the Communist Party of the Soviet Union was generally perceived as covering that of the Bolshevik faction of the Russian Social Democratic Labour Party from which it evolved. In 1912, the party formally split, and the predecessor to the Communist Party of the Soviet Union became a distinct entity. Its history since then can roughly be divided into the following periods:
In political ideology, a deviationist is a person who expresses a deviation: an abnormality or departure. In Stalinist ideology and practice, deviationism is an expressed belief which does not accord with official party doctrine for the time and area. Accusations of deviationism often led to purges. Forms of deviationism included revisionism, dogmatism, and bourgeois nationalism.
