An artist’s depiction of the passenger ship, Lusitania, sinking after being torpedoed by a German U-boat in 1915, published in the London News. The ship was bound for Liverpool, carrying a number of United States citizens that lost their lives in the sinking. England and France, making little headway on the Western Front in the First World War, repeatedly called upon the United States to enter the war. The sinking of the Lusitania was one of the key events that changed the opinion of the predominantly isolationist-leaning United States citizens towards a willingness to entering the war.
