Answer:
The Bolsheviks defeated anti-Communists because their actions were approved by the people and they were supported by the military.
Step-by-step explanation:
The Russian Revolution of 1917 was one of the volatile political protests of the century. The result of this protest resulted in the uprooting of the Romanov Dynasty and czarist rule.
The Bolsheviks were led by Vladimir Lenin and were successful in driving out the imperial dynasty. After the Russian Revolt of 1917, the Russian Civil War began in 1918 in which anti-Bolsheviks (White and anti-Communist) stood against Bolsheviks (Reds and Communists). The Bolsheviks were able to defeat Whites as they have already become popular amongst them because of the Russian Revolution of 1917 and were backed up by the military.
