According to Marquette University, the Russian Revolution of 1917 resulted in the end of the tsar and aristocracy along with the beginning of communism. After a series of foreign wars and taxes on the Russian population, the Russian Revolution overthrew Tsar Nicholas II in February 1917. After disagreement between the two main political parties, another revolution in October 1917 declared Bolshevik Vladimir Lenin leader.
After the Russian Revolution, a series of battles and statutory changes permanently altered Russia’s political history. Lenin ended participation in World War I after seizing power. With a lack of resources for the current population and veterans from World War I, a civil war erupted between the Reds and Whites. The Whites propagated the reinstatement of the monarchy to fix the problems in the country, and the Reds constituted the Bolsheviks. In order to allay fears of another revolution, a bloody civil war consumed the country. The Reds killed dissenters and the nobility, and a new era of terror crippled the country over the next several decades.
The Bolsheviks renamed the country The Union of Soviet Socialist Republics in 1922 at the end of the civil war, solidifying the Russian Revolution of 1917. The Bolshevik regime remained in power until the fall of the Soviet Union in 1991.
