How did Russian Civil War begin?

It began when a few groups in Russia decided to try out communism, and then they were called the Red Army. The White Army was the group of people that were still either loyal to the Tsar, or they opposed Communism. It really broke out when the Red Army assassinated Tsar Nicholas, his wife Alexandra, their daughters Olga, Tatiana, Marie, and Anastasia, as well as their son Alexei and some of their friends and faithful servants, who were all imprisoned in the Ipatiev house. Then, of course, people went crazy, one party against another, with the peasants all over Russia playing a large part.
