 Wakeman says many Native nations were not in attendance as the summit was held the day before celebrations for the Battle of Little Bighorn when Lakota and Northern Cheyenne defeated General Custer in what is now southeastern Montana. The governor's office says all nine tribes were represented at the summit, but at least three tribes, Lower Brule, Rosebud, and Yankton, confirmed to SDPB they did not send representatives to attend the summit.
