Zimmermann Telegram

The Zimmermann Telegram was a secret message sent by Germany to Mexico in January 1917 during World War I. It proposed a military alliance between Germany and Mexico, suggesting that Mexico should join the war against the United States in exchange for Texas, New Mexico, and Arizona. The British intercepted and decrypted the message, sharing it with the U.S., which ignited public outrage and shifted American sentiment toward entering the war. The telegram played a crucial role in turning the tide of U.S. involvement, ultimately contributing to the defeat of the Central Powers.
