Zimmermann Telegram sent by German Foreign Office to Mexico

German Foreign Secretary Arthur Zimmermann sent a secret diplomatic note proposing a German–Mexican military alliance against the United States if the U.S. entered the war.

Although not immediately public, the telegram's later disclosure to the U.S. public dramatically shifted American opinion against Germany and became a key factor leading toward U.S. entry into World War I.
