The Zimmermann Telegram (also called the Zimmermann Note) was a telegram sent to Mexico from Germany on January 16, 1917. It was what made America enter World War I. It is named for the German man who sent it, Arthur Zimmermann. Zimmermann was the German Foreign Secretary (took care of things with other countries). Zimmermann sent it to the German ambassador in the United States, Johann von Bernstorff. Bernstorff then sent it to the German ambassador in Mexico, Heinrich von Eckardt.
The telegram's message was:
- FROM 2nd from London # 5747.
- "We intend to begin on the first of February unrestricted submarine warfare. We shall endeavor in spite of this to keep the United States of America neutral. In the event of this not succeeding, we make Mexico a proposal of alliance on the following basis: make war together, make peace together, generous financial support and an understanding on our part that Mexico is to reconquer the lost territory in Texas, New Mexico, and Arizona. The settlement in detail is left to you. You will inform the President of the above most secretly as soon as the outbreak of war with the United States of America is certain and add the suggestion that he should, on his own initiative, invite Japan to immediate adherence and at the same time mediate between Japan and ourselves. Please call the President's attention to the fact that the ruthless employment of our submarines now offers the prospect of compelling England in a few months to make peace." Signed, ZIMMERMANN
The telegram told the ambassador to ask the Mexicans to join the war on the German side by attacking America. Germany promised to help Mexico take back land the United States had taken from Mexico in the Mexican–American War. These places were Texas, New Mexico, and Arizona. Germany wanted Mexico to enter the war so America would be too busy to help the enemies of Germany. Mexico was already busy with the Mexican Revolution and did not like the idea.
The British secretly got the telegram. They were able to decode the telegram. They held on to the telegram until February 24, 1917. They gave it to President Woodrow Wilson of the United States of America. President Wilson published the telegram so the people would know about it. The telegram made the American people angry. Wilson asked the United States Congress for a Declaration of war against Germany. Congress accepted the request on April 2, 1917. The United States of America announced war on Germany on April 6, 1917. Americans were already angry over German submarines sinking ships, but this telegram is what made America come into the war.
