World War I

(1914—1918)

The causes of World War I lie in the intricate alliance system that existed in Europe prior to 1914. The trigger was the assassination of Austrian Archduke Franz Ferdinand in Sarajevo on June 28, 1914. It was duty, not dedication to a cause that brought Russia, Britain, and France to Serbia’s aid while Germany and Austria-Hungary prepared for war. World War I, the “War to End All Wars,” grew out of long-held alliances and resulted in a lost generation, disillusioned by war. Many countries, like the United States, vowed to remain neutral yet were inevitably brought into the conflict in response to German aggression. Despite its isolationist policy, the U.S. ultimately declared war on Germany in 1917. World War I was the first major war where aircraft played a significant combat role. It also set the stage for WWII as German citizens nursed a grudge for decades, feeling that the armistice treated them unfairly and prevented Germany from recovering after the war.

The Zimmerman Telegram

Two moves by the Germans brought the United States into World War I: Germany’s decision to wage unrestricted submarine warfare and the Zimmermann Telegram. On March 1, 1917, the United States intercepted a telegram from Arthur Zimmermann, German foreign secretary, to Mexico. The coded correspondence proposed an alliance between Mexico and Germany, and vaguely promised Mexico the return of Texas, New Mexico, and Arizona if Mexico helped Germany attack the United States. This and the new German policy of unrestricted submarine warfare forced the United States to forego neutrality and enter World War I on April 2, 1917. The entrance of America on the side of Great Britain and France gave the Allies the last push forward to win the war.
