EXPLANATIONS BELOW
Concept note-1: -The Zimmermann Telegram (or Zimmermann Note or Zimmerman Cable) was a secret diplomatic communication issued from the German Foreign Office in January 1917 that proposed a military alliance between Germany and Mexico if the United States entered World War I against Germany.
Concept note-2: -This telegram, written by German Foreign Secretary Arthur Zimmermann, is a coded message sent to Mexico, proposing a military alliance against the United States.
Concept note-3: -The note revealed a plan to renew unrestricted submarine warfare and to form an alliance with Mexico and Japan if the United States declared war on Germany. The message was intercepted by the British and passed on to the United States; its publication caused outrage and contributed to the U.S. entry into World War I.
Concept note-4: -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.
Concept note-5: -In the message, Zimmermann instructed the German diplomats to approach the Mexican government, if United States entered the war in Europe, to offer an alliance between Germany and Mexico.
