U.S. Entered World War I
April 6, 1917

Disagreements in Europe over territory and boundaries, among other issues, came to a head with the assassination of the Archduke Ferdinand of Austria by a Serbian zealot on June 28, 1914. Exactly one month later, war broke out. In 1915, the British passenger liner the Lusitania was sunk by a German submarine, killing 128 Americans and futher heightening tensions. By the end of 1915, Austria-Hungary, Bulgaria, Germany, and the Ottoman Empire were battling the Allied Powers of Britain, France, Russia, Italy, Belgium, Serbia, Montenegro and Japan. In 1917, the U.S. entered the war. Germany formally surrendered on November 11, 1918, and all nations agreed to stop fighting while the terms of peace were negotiated.
