Gallery description: When the United States entered World War I on April 6, 1917, nearly three years after the war had begun, the nation was shocked.  Woodrow Wilson had clung to an isolationist campaign during the 1916 presidential election, but once he was inaugurated he asked Congress for a declaration of war against the Central Powers.  Both the men who were drafted and the families who awaited them at home needed some sense of patriotism and community to help them through the war.  One way the U.S. did this was through the distribution of music: both in the military camps and as popular songs released to the general public.  The following selection shows some examples of the music published during this time.
