The Lusitania was a British passenger ship sunk by a German submarine in 1915, killing nearly 1,200 people, including 128 Americans. The deaths intensified American anger and suspicion toward Germany, so public opinion turned against the Germans even more. The sinking did not immediately bring the United States into the war, but it worsened relations.
