How did world war 1 affect the Russian revolution in 1917?

World War I significantly exacerbated existing social, economic, and political tensions in Russia, leading to widespread dissatisfaction with the Tsarist regime. The war caused severe casualties, food shortages, and military failures, which fueled public unrest and strikes. This discontent culminated in the February Revolution of 1917, which resulted in the abdication of Tsar Nicholas II and the establishment of a provisional government. Ultimately, the chaos and instability created by the war set the stage for the Bolshevik Revolution later that year, as revolutionary factions capitalized on the desire for peace, land, and bread.
