The Lusitania, a British ocean liner noted for its speed, size, and luxurious interior, docks at a pier in an undated photograph. The Cunard Line ship was launched in 1907 and torpedoed by a German U-boat in 1915. The Luisitania sank, killing nearly 1,200 civilian passengers and crew members, including 128 Americans. The tragedy helped influence American popular opinion about the war in Europe, turning the country's largely isolationist stance into support for declaring war on Germany.
