Most Significant - Impact of the First World War

Series of defeats and increasing death toll
Focus on army meant there were more food shortages and lack of equipment
Reflected badly on Tsar Nicholas II as he'd taken personal command of the army in September 1915
People felt betrayed and angry at government.
Soldiers weren't loyal to the Tsar, mutinies = Tsar losing status and control. Russians wanted to change government. (Defections in the armed government and incompetence of Nicholas II too)
Took personal control of the army despite no military training (Incompetence of Nicholas II)
Rasputin began to run the government when Nicholas went to fight in frontline, anger amongst Russians built (Actions of Rasputin)
Bread had to be rationed as it was going to the army. Farmers were leaving farmland to fight = food shortages (Social and economic problems)
