Why did Russian civil war breake out in 1918
Finally, these groups within Russia were helped by the Great Powers, angry that
Russia had dropped out of the First World War. They were afraid because the
Bolsheviks believed in World Revolution, the Bolsheviks set up the Comintern, led by
Zinoviev, which said it would cause communist revolutions all over the world.
Consequently, the Allies sent armies to destroy the Bolsheviks, British, American and
French armies attacked from Archangel, Ukraine, and Vladivostock.
As an result Bolsheviks had their victory and a huge establishment of the Soviet
Union. Also a lots of countries got their independence like Estonia, Finland, Latvia,
Lithuania and Poland.
Reason for Russian civil war in 1918 was basically the oppositional ideologies
fighting for government control and because of that many people lost their lives.
