Lusitania: Germans Provoke US

     When the German submarine (U-boat) U-20 torpedoed the British ocean liner Lusitania carrying 1,962 passengers on May 7, 1915, the act would ultimately trigger the United States' entry into WWI.

     Until that time, the United States had chosen to remain neutral. However, between the continued German submarine warfare and the British interception of the Zimmerman Telegram in January 1917, President Woodrow Wilson asked the United States Congress for permission to engage in war.

     Complying, Congress officially declared war on Germany and its allies on April 6, 1917.
