What document encourage Mexico to reconquer three American states in return for German help

1 answer

The document you are referring to is the "Zimmermann Telegram." Sent in January 1917 by German Foreign Minister Arthur Zimmermann to the German ambassador in Mexico, the telegram proposed a military alliance between Germany and Mexico in the event that the United States entered World War I against Germany. In the proposal, Germany promised to support Mexico in reconquering the territories of Texas, New Mexico, and Arizona in exchange for Mexico's support. The telegram was intercepted and decoded by British intelligence, and its revelation to the United States helped sway public opinion against Germany and contributed to the U.S. decision to enter the war.
