Czar Nicholes II abdicated his throne and was later on executed. Russians had a revolution because they wanted a better government and wanted to end the war. In the begining, Nicholes lead Russia, but he wasn't good at it. The things that brought Russia to WWI was Militarism, Nationalism, the assasin of franz ferdinand, etc.
Militarism was when other countries from WWI were increasing militay power to fight againts their enemies. They even had plans to see how they were gonna fight in the war. Nationalism was something that the countries had in mind to caputre somefor their lands.
The most big reason that made Russia go into war was that Franz Ferdinand was killed by a serbian man. The Serbian man was in a group called the "dark man" which was his job to kill franz from going to other countries.
