Joseph Stalin( 06 December 1878 – 05 March 1953) was a revolutionary in the Russian Empire and political leader who led the Soviet Union from 1924 until his death in 1953. He held power as 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). Initially governing the country as part of a collective leadership, he consolidated power to become a dictator by the 1930s. Ideologically adhering to the Leninist interpretation of Marxism, he formalised these ideas as Marxism–Leninism, while his own policies are called Stalinism.
Widely considered to be one of the 20th century's most significant figures, Stalin was the subject of a pervasive personality cult within the international Marxist–Leninist movement, which revered him as a champion of the working class and socialism. Since the dissolution of the Soviet Union in 1991, Stalin has retained popularity in Russia and Georgia as a victorious wartime leader who cemented the Soviet Union's status as a leading world power. Conversely, his regime has been described as totalitarian, and has been widely condemned for overseeing mass repression, ethnic cleansing, wide-scale deportation, hundreds of thousands of executions, and famines that killed millions.
