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. |
