A View of WW1 as a Russian Student

Due to the needs of modernizing Russia, Russia had an increase in the number of universities and students. Being a student of a university in Russia, one would criticize autocracy, and see it as their mission to transform Russia. These students were known as "intelligentsia". In hopes of bringing change to the countryside, students organized a populist movement. Such idealists educated the peasants to make them more politically aware, and eventually formed the People's Will, which eventually led to murders of public officals to hasten the day of revolution.
They supported the idea getting rid of autocracy, though it is not clear if they supported the war. If I could make an inference, I would say that they did support the war, because they supported the peasants' knowlegde of what was occuring politically, and how unjust the peasants were being treated, and conflict to change that was inevitable.
