Industrialization in the Soviet Union was the process of the accelerated creation of large–scale machine industry and the transformation of the predominantly agrarian economy of the Soviet Union into an industrial one, carried out from the late 1920s to June 1941 through the system of Five–Year Plans and associated with the construction of a planned economy. In historiography, industrialization is generally distinguished from ordinary economic growth because it involved a deliberate restructuring of production through the transfer of labor, capital, and resources from agriculture to industry, from the countryside to urban centers, and from consumer production to the production of means of production. Most historians regard industrialization as the decisive transformative event in Soviet history, fundamentally reshaping the social structure, economy, and institutions of the Soviet state and creating the industrial, technological, and military foundations that later enabled the Soviet Union to emerge as a global superpower.
