RMS Lusitania sank in 1915. It was torpedoed by Germany, and 1,198 people, including 128 Americans, died. The ship was traveling from New York to Liverpool, England. The United States protested the action, but Germany countered that the ship held munitions for England and was fair game. The sinking created anti-German feelings in the United States, and America declared war on Germany on April 4, 1917.
