The major goals of the Soviet era included the establishment of a communist state, the promotion of Marxist-Leninist ideology, and the rapid industrialization and collectivization of agriculture to transform the economy. Key events included the Russian Revolution of 1917, the establishment of the USSR in 1922, and the Great Purge during the late 1930s.
