The Russian Civil War was fought between 1918-1921 and was between the Bolshevik Red Army and opposing anti-Bolshevik White armies. The Bolsheviks faced opposition from supporters of the Tsar, socialist groups opposed to Bolshevik methods, and capitalists and landowners who lost wealth due to Bolshevik reforms. Though the Bolsheviks controlled major cities, most of Russia was held by opposing forces. The Red Army, led brilliantly by Trotsky, eventually defeated the various White armies through separate campaigns, exploiting weaknesses in White coordination and popularity. By 1921 the Bolsheviks had defeated all armed resistance and consolidated control over Russia.
