The Washitaw Nation, or Washitaw de Dugdahmoundyah, is a group of Black Americans that claim to be a sovereign Native American nation within the boundaries of the United States. Their name is taken from that of the Ouachita tribe, who are also eponymous of the Washita River and of Washita, Oklahoma. The group is part of the sovereign citizen movement, a movement whose members generally believe that they are not subject to any statutes or proceedings at the federal, state, or municipal levels.
