A Global War
In 1914 war erupted in Europe. Rival nations around the globe, tangled in webs of alliances, took sides: Germany, Austria-Hungary and other Central Powers united against the Allies that included Britain, Canada, France, Italy, Japan, and Russia.
After three years of fighting, both sides were dug in and deadlocked, facing each other in trenches that ran nearly 500 miles across northern France—the notorious Western Front. When the United States entered the war on April 6, 1917, few could foresee that American troops would break the impasse, bringing the war to an end by November 11, 1918.
