For months, the Standing Rock Sioux Tribe and its allies have protested the routing of an oil pipeline near its reservation in North Dakota – and recently won a temporary victory when federal officials put a hold on the pipeline’s completion. But the protest itself has been a significant event in the 200-year history of American Indian activism, says Frederick E. Hoxie, who told that history in the book “This Indian Country: American Indian Activists and the Place They Made.” Recently retired as a University of Illinois professor of history, law and American Indian studies, he spoke with the Illinois News Bureau about the protest and what it means.
