Overview
World War I (1914–1918) was the first truly global armed conflict, involving most of Europe's major powers plus nations worldwide. Also called 'The Great War', it introduced industrial-scale warfare: machine guns, poison gas, tanks, and aerial bombing. The Western Front became a brutal stalemate with millions dying in trenches. The war killed 17–22 million people (civilian + military) and set the stage for WWII.
