who did the us fight in world war i

The United States fought primarily against Germany and Austria-Hungary in World War I, as part of the Allied powers alongside Britain, France, and others.

Core answer

• The U.S. declared war on Germany on April 6, 1917, ending its earlier neutrality in the conflict.

• Later, the U.S. also declared war on Austria-Hungary on December 7, 1917.

• The U.S. did not formally declare war on the other Central Powers (the Ottoman Empire and Bulgaria), so most American combat was directed against German forces on the Western Front and, to a lesser extent, Austro-Hungarian forces.

Quick context

• World War I was fought mainly between the Allied Powers (including Britain, France, Russia, later the U.S. and others) and the Central Powers (Germany, Austria-Hungary, the Ottoman Empire, and Bulgaria).

• When the U.S. entered on the Allied side in 1917, its troops, the American Expeditionary Forces under General John J. Pershing, were sent largely to France to help stop and then push back German offensives.
