During World War I, Germany became an enemy of America. As such, many everyday cultural ties to Germany were altered to express a more American or patriotic feel. For example, hamburgers, which were named for the German city of Hamburg, were changed to Salisbury steaks. Frankfurters, named for the German city of Frankfurt, became known as "liberty sausages." Although "liberty sausages" faded into history, Salisbury steak continues to be a popular food in America.
