The result of the Russian Civil War, fought from 1917 to 1922, was the establishment of the Soviet Union under the leadership of the Bolshevik Party, led by Vladimir Lenin. The war was primarily between the Red Army (Bolsheviks) and the White Army (anti-Bolsheviks, including monarchists and liberals). The victory of the Bolsheviks solidified their control over Russia, allowing them to implement extensive political, social, and economic reforms. This conflict also contributed to the rise of communism in Russia and shaped the country's future, leading to a one-party state and establishing the foundation for future tensions with the West during the Cold War.
