Joseph Stalin
Joseph Vissarionovich Stalin (18 December [O.S. 6 December] 1878 – 5 March 1953) was a Georgian revolutionary and the ruler of the Soviet Union from 1927 until 1953. He served as both General Secretary of the Communist Party of the Soviet Union (1922–1952) and Chairman of the Council of Ministers of the Soviet Union (1941–1953). 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.
