In the summer of 1918, the white chairman of the National Association for the Advancement of Colored People, Major Joel E. Spingarn, called for urgent congressional action on mob violence. He seized the opportunity of a post in the Military Intelligence Branch (MIB) of the War Department General Staff in Washington, D.C., to put forward a “constructive programme,” the central idea of which was the passage of a bill to make lynching in wartime a federal offense. Attempting to exploit the peculiar circumstances of the national emergency and the expansion of federal powers during World War I, Spingarn also proposed a series of more modest initiatives designed to lessen discrimination and raise black morale. The official reaction to the arguments he advanced in support of his program sheds light on the reluctance of the Democratic administration of Woodrow Wilson to develop a policy on race relations. It also suggests some of the problems and hazards facing a would-be reformer working from within.
