Joseph Vissarionovich Stalin was a Georgian revolutionary and political leader who governed the Soviet Union from 1924 until his death in 1953. He served as both General Secretary of the Communist Party of the Soviet Union and Chairman of the Council of Ministers of the Soviet Union. Despite initially governing the country as part of a collective leadership, he ultimately consolidated power to become the Soviet Union's dictator by the 1930s. A communist ideologically committed to the Leninist interpretation of Marxism, Stalin formalised these ideas as Marxism–Leninism while his own policies are known as Stalinism.
Born to a poor family in Gori in the Russian Empire, Stalin attended the Tbilisi Spiritual Seminary before eventually joining the Marxist Russian Social Democratic Labour Party. He went on to edit the party's newspaper, Pravda, and raised funds for Vladimir Lenin's Bolshevik faction via robberies, kidnappings and protection rackets. Repeatedly arrested, he underwent several internal exiles. After the Bolsheviks seized power during the October Revolution and created a one-party state under the newly formed Communist Party in 1917, Stalin joined its governing Politburo.
