The history of the Soviet Union between 1927 and 1953 covers the period in Soviet history from the establishment of Stalinism through victory in the Second World War and down to the death of Joseph Stalin in 1953. He sought to destroy his enemies while transforming Soviet society with central planning, in particular through the forced collectivization of agriculture and rapid development of heavy industry. Stalin consolidated his power within the party and the state and fostered an extensive cult of personality. Soviet secret-police and the mass-mobilization Communist Party served as Stalin's major tools in molding Soviet society. Stalin's methods in achieving his goals, which included party purges, political repression of the general population, and forced collectivization, led to millions of deaths: in Gulag labor camps and during famine.
