As head of the Politburo of the Central Committee of the Communist Party of the Soviet Union, Stalin consolidated near-absolute power in the 1930s with a Great Purge of the party that claimed to expel "opportunists" and "counter-revolutionary infiltrators".
The Soviet Union entered a series of five-year plans which began in 1928 under the rule of Joseph Stalin. Stalin launched what would later be referred as a "revolution from above" to improve the Soviet Union’s domestic policy. The policies were centered around rapid industrialization and the collectivization of agriculture. Stalin desired to remove and replace any policies created under the New Economic Policy.I think it should be this one.
