What was the purpose of the zimmermann telegram?

The Zimmermann Telegram was a secret diplomatic communication sent by Germany to Mexico in January 1917 during World War I. Its purpose was to propose a military alliance between Germany and Mexico in the event that the United States entered the war against Germany. Germany promised to support Mexico in reclaiming territories lost to the U.S., such as Texas, New Mexico, and Arizona. The interception and publication of the telegram by British intelligence helped galvanize American public opinion against Germany and contributed to the U.S. entering the war.
