Joseph Stalin or Iosif Vissarionovich Stalin was the de facto leader of the Soviet Union from the mid-1920s until his death in 1953. Among the Bolshevik revolutionaries who took part in the Russian Revolution of 1917, Stalin was appointed General Secretary of the party's Central Committee in 1922. He subsequently managed to consolidate power following the 1924 death of Vladimir Lenin through expanding the functions of his role, all the while eliminating any opposition. He held this nominal post until abolishing it in 1952, concurrently serving as the Premier of the Soviet Union after establishing the position in 1941.
