What role did the First World War play in the development of the revolution?

The First World War exacerbated the already difficult situation in the country. It lasted for several years, the people were exhausted by it, many goods could not be obtained due to the orientation of many enterprises towards the production of goods necessary for the front. The lack of high-profile victories allowed the disaffected to use military action as an indicator of the inability of the tsarist government to successfully rule the country. Adding to this the urgent problems unresolved in the country, the leaders of the revolutionary circles could count on an early revolution.
