In 1928 [[Joseph Stalin]] introduced the First Five-Year Plan for building a socialist economy. In industry, the state assumed control over all existing enterprises and undertook an intensive program of industrialization; in agriculture, the state appropriated the peasants' property to establish collective farms. These sweeping economic innovations produced widespread misery, and millions of peasants perished during forced collectivization. Social upheaval continued in the mid-1930s when Stalin began a purge of the party; out of this purge grew a campaign of terror that led to the execution or imprisonment of untold millions of people from all walks of life. Yet despite this turmoil, the Soviet Union developed a powerful industrial economy in the years before World War II.
