Stalin's final moments - Timewatch: Who Killed Stalin - BBC
Joseph Stalin was a Soviet revolutionary and politician of Georgian ethnicity. He ruled the Soviet Union from the mid-1920s until his death in 1953, holding the titles of General Secretary of the Communist Party of the Soviet Union from 1922 to 1952 and the nation's Premier from 1941 to 1953. Initially presiding over an oligarchic one-party regime that governed by plurality, he became the de facto dictator of the Soviet Union by the 1930s. Ideologically committed to the Leninist interpretation of Marxism, Stalin helped to formalise these ideas as Marxism–Leninism while his own policies became known as Stalinism.
