[2] They may have formed as a tribe within the Lakota relatively recently, as the first mention of the Hunkpapa in European-American historical records was from a treaty of 1825.
The US representatives gave a medal to Little White Bear, who they understood was the principal Hunkpapa chief; they did not realize how decentralized Native American authority was.
Some visiting Hunkpapa may have benefitted from Dr. M. Martin's inoculation of about 900 southern Lakota (no divisions named) at the head of Medicine Creek that autumn.
[7] The boundaries for the Lakota Indian territory were defined in the general peace treaty negotiated near Fort Laramie in the summer of 1851.
[1] In addition to dealing with warfare, they suffered considerable losses due to contact with Europeans and contracting of Eurasian infectious diseases to which they had no immunity.
The Hunkpapa gave some of their remote relatives among the Santee Sioux armed support during a large-scale battle near Killdeer Mountain in 1864 with U.S. troops led by General A.
[14] The Lakota pressed the Crow Indians to the point that they reacted like other small tribes: they called for the U.S. Army to intervene and take actions against the intruders.
[15] In the late summer of 1873, the Hunkpapa boldly attacked the Seventh Cavalry in United States territory north of the Yellowstone.
[16] Battles such as Honsinger Bluff and Pease Bottom took place on land purchased by the United States from the Crow tribe on May 7, 1868.
[17] These continual attacks, and complaints from American Natives, prompted the Commissioner of Indian Affairs to assess the full situation on the northern plains.
It comprises land along the Grand River which had been used by the Arikara Indians in 1823; the Hunkpapa "won the west" half a century before the whites.
By 1891, the majority of Hunkpapa Lakota, about 571 people, resided in the Standing Rock Indian Reservation of North and South Dakota.
