The sinking of the RMS Lusitania by a German submarine changed World War I.  Though carrying ammunition to support The War effort, it also carried nearly 2,000 passengers and crew, most of whom died.  This incensed the British and Americans, but most Americans still wanted no involvement in The War.  Unable to swing opinion towards War, President Wilson sent multiple demands that the Germans cease all actions against mercantile shipping.
