How did world war 1 contribute to the of the Russian revolution?

World War I significantly exacerbated Russia's existing social and economic issues, leading to widespread discontent among the populace. The war caused severe military losses, economic hardship, and food shortages, which intensified public frustration with the Tsarist regime. This unrest ultimately fueled the February Revolution of 1917, which led to the abdication of Tsar Nicholas II and the establishment of a provisional government. The failure of this government to address key issues paved the way for the Bolshevik Revolution later that year, fundamentally transforming Russia's political landscape.
