Remember, World War 1 was the first of two wars, which started on July 28th, 1914 and ended on November 11th, 1918.
A major factor that led the United States to enter World War 1 would be because of Germans attacking American ships that had Americans on it, using submarines. Another reason would be because of a British telegram, called the Zimmerman Telegram/Note, that offered an alliance between Germany and Mexico.
