The Zimmermann Telegram was a secret message sent by Germany to Mexico during World War I. In the message, Germany promised to help Mexico regain territory it had lost to the U.S. in exchange for Mexico's support in the war effort. When the contents of the telegram were intercepted and made public by British intelligence, American public opinion turned against Germany. This, in turn, helped to sway the U.S. government to enter the war on the side of the allies.
