What was the Zimmermann Telegram?

• A. A 1917 German proposal to Mexico to ally against the United States, intercepted and publicized in the US.
• B. A British entreaty to invade Germany across the Alps.
• C. A secret Czarist order to negotiate peace with Austria.
• D. A French diplomatic note about naval arms limits.

Answer: (A)

This item centers on a diplomatic telegram from Germany during World War I that proposed an alliance with Mexico against the United States. The telegram, sent in early 1917, carried a bold offer: Germany would support Mexico in recovering territory it had lost to the U.S.—Texas, New Mexico, and Arizona—if Mexico would join Germany’s side should the United States enter the war. The British intercepted the message and decrypted it, then shared it with the United States. When the revelation reached American newspapers, it sparked outrage and helped shift public opinion toward entering the war. This is why the Zimmerman Telegram is remembered as a turning point that contributed to the U.S. decision to declare war on Germany. The other choices describe events or orders that did not occur, so they don’t fit what the telegram actually was.
