Soviet Union
At the same time, workers' councils, known as Soviets, sprang up across the country. The Bolsheviks, led by Vladimir Lenin, pushed for socialist revolution in the Soviets and on the streets. In November 1917, during the "October Revolution", they took power from the Provisional Government. In December, the Bolsheviks signed an armistice (peace) with the Central Powers. In March, after more fighting, the Soviets quit the war for good and signed the Treaty of Brest-Litovsk.
