How did World War 1 connect with the Russian Revolution?

World War I significantly contributed to the Russian Revolution by exacerbating existing social, economic, and political tensions in Russia. The war placed immense strain on the Russian economy, leading to food shortages, military defeats, and widespread discontent among soldiers and civilians alike. In 1917, this discontent fueled the February Revolution, which resulted in the abdication of Tsar Nicholas II, followed by the Bolshevik-led October Revolution, which ultimately established a communist government. Thus, the chaos and challenges of World War I acted as a catalyst for revolutionary change in Russia.
