The Old Bolsheviks, also called the Old Bolshevik Guard or Old Party Guard, were members of the Bolshevik faction of the Russian Social Democratic Labour Party prior to the Russian Revolution of 1917. Many Old Bolsheviks became leading politicians and bureaucrats in the Soviet Union and the ruling Communist Party. While some died over the years from natural causes, many were removed from power, imprisoned in gulags or executed in the late 1930s, as a result of the Great Purge by Joseph Stalin.
Lazar Kaganovich (1893–1991) joined the Bolsheviks in 1911, survived Stalin's purge, and died only five months before the dissolution of the Soviet Union.
