Zimmermann Telegram, 1917.
The Zimmermann Telegram (also known as the Zimmermann Note) helped bring the United States into World War I. This coded note was written by German Foreign Secretary Arthur Zimmermann. Zimmermann sent the note to Mexico in an attempt to create a military alliance between Germany and Mexico. Intercepted and decoded, the Zimmermann Telegram infuriated Americans because of the threat such a proposed alliance would pose to the United States. The U.S. Congress declared war on Germany in 1917, thereby entering World War I. |
