The event that caused the death of 14,000,000 Russians was the Russian Civil War. Explain the causes of Russia's Civil War and its outcome. The causes of Russia's Civil War were the failure of provisional government of Kerensky, the growing power of the soviets, the treaty of Brest-Litovsk angered Russians, and the Bolsheviks wanted to wipe out all their enemies. The outcome was the Bolshevik victory over the Whites and 14,000,000 dead.
Why did the Bolsheviks win the Russian Civil War? Fresh from seizing control of Russia from the hands of the Provisional Government, the Bolsheviks' next step was to safeguard their fragile grip on the reigns of power. Lenin negotiated peace with Germany and therefore an end to Russia's role in World War I. He could not, however, avoid a civil war in Russia. The Bolsheviks were made to fight for control of the country. The Russian Civil War raged from 1918 until the start of 1921. During this time, the Bolsheviks faced massive opposition to their rule in the form of the White Armies, led by former officers of the Tsarist state, and also from intervention by the forces of foreign countries.
