The outcome of the Russian Civil War (1917-1922) was the establishment of a Bolshevik government headed by the Communist Party, under the leadership of Vladimir Lenin. The conflict arose following the Russian Revolution, where the Bolshevik Red Army fought against the White Army, a coalition of anti-Bolshevik forces, along with various nationalists and foreign interventionists. The Reds' victory solidified the Bolshevik's control over Russia, leading to the formation of the Soviet Union in 1922. The war had devastating consequences, with millions of deaths and immense social and economic disruption, but it ultimately set the stage for the emergence of the Soviet state and the implementation of Communist policies.
