Zimmermann Telegram

The Zimmermann Telegram was a 1917 coded message from the Foreign Secretary of the German Empire, Arthur Zimmermann to the German Minister to Mexico, Heinrich von Eckard, offering United States territory to Mexico in return for joining the German cause. This message helped draw the United States into World War I and thus changed the course of history.

The coded message was intercepted and deciphered by the British Secret Intelligence Service, Military Intelligence, Section 2 (MI2).
