Changes

The Soviet Union was established in December 1922 by the leaders of the Russian Communist Party (Bolshevik) on territory generally corresponding to that of the old Russian Empire. A spontaneous popular uprising in Petrograd overthrew the imperial government in March 1917, leading to the formation of the Provisional Government, which intended to establish democracy in Russia. At the same time, to ensure the rights of the working class, workers' councils (''soviets'') sprang up across the country. The Bolsheviks, led by Vladimir I. Lenin, agitated for socialist revolution in the soviets and on the streets, and they seized power from the Provisional Government in November 1917. Only after the ensuing Civil War (1918-21) and foreign intervention was the new communist government secure.

From its first years, government in the Soviet Union was based on the one-party rule of the Communists, as the Bolsheviks called themselves beginning March 1918. After unsuccessfully attempting to centralize the economy during the Civil War, the Soviet government permitted some private enterprise to coexist with nationalized industry in the 1920s. Debate over the future of the economy provided the background for Soviet leaders to contend for power in the years after Lenin's death in 1924. By gradually consolidating influence and isolating his rivals within the party, Joseph V. Stalin became the sole leader of the Soviet Union by the end of the 1920s.

In 1928 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.
