Changes

==History==

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.
