Answer: Russia suffered huge casualties in the war.
Step-by-step explanation:
In addition to the suffering of many people and the enormous material destruction, Russia was also hit by the civil war. A revolution started by the Bolsheviks broke out in Russia. It was an effort to remove the incompetent imperial government. Russia was lagging behind industrial flows, and its European neighbors were at a much higher development stage. In Russia, there was a strengthening of nationalism, given that certain parts of the country came under the control of Germany and the Austro-Hungarian government.
