By Jennifer Rosenberg. The Zimmermann Telegram was a coded message sent from German Foreign Minister Arthur Zimmermann to Germany's ambassador in Mexico, Heinrich von Eckhardt, in January 1917. The British managed to intercept this coded message and were able to decipher it.
In February the British gave the American ambassador in London a copy of an intercepted German telegram. The telegram came from the German Foreign Secretary, Arthur Zimmerman, to the German ambassador to Mexico. Zimmerman proposed that in the event of war with the US, Germany and Mexico would join in an alliance. Germany would fund Mexico's conflict with the US. With victory achieved, Mexico would regain her lost territories of Arizona, Texas and New Mexico.
