The Russian Civil War was a massive armed conflict taking place between multiple factions in the Russian Empire. The war lasted for nearly ten years and resulted in 500,000 deaths and many more casualties.
The war stemmed from the Russian defeat during World War I. This, along with nationalist movements and the tsar's total rule resulted in a full blown revolution. Ideological splits among groups led to many splinter groups, widening the conflict. Foreign powers took an interest in the conflict, supporting different groups. Near the end of the war two powers emerged, which were the St. Petersburg Soviet and the White Army. The Soviets defeated the Whites, however they continued to operate as an underground resistance movement.
The Civil War would eventually lead to World War II during the 1930s, and would continue to effect modern politics.
