Aŋpétu Wašté Wiŋ was born on this day in 1889 on the South Dakota Yankton Indian Reservation, and raised on Pine Ridge. She was an ethnographer, linguist, and writer known for her important work recording oral histories and documenting the Dakota language. She is also known for working with Franz Boas and from the Akta Lakota Museum: "Deloria did her own research as well, interviewing tribal elders, writing Dakota grammar books, translating ceremonial texts, writing the novel ‘Waterlily,’ and conducting studies for the Bureau of Indian Affairs in regards to the Lumbee of Robeson county and socio-economic challenges on the Navajo Reservation."

In the aftermath of the Bannock War, US President Rutherford B. Hayes ordered the forced relocation of the Wadatika Band of Northern Paiutes by military escort >300 miles north to the Yakama Reservation in Washington State. Although the Wadatika band was not involved in any of the battles or raids of the Bannock war, they were nevertheless forcibly removed and forbidden to return to their home, the Malheur reservation for five years. 543 Paiute and Bannocks were force marched north. After five years in a concentration camp, they returned home to find it had been returned to “Public Domain” and opened to settlers. These landless Paiutes are the ancestors who survived and fought to create the Burns-Paiute Tribe. They lived together in a tight-knit community and often successfully hid their children from Indian Agents who came to try to take their children to boarding schools, thus retaining their language and traditional practices in meaningful ways. Other Paiutes went to Duck Valley Indian Reservation.
