In June 1899, negotiation began on Treaty No. 8, which covered 840,000 square kilometers in the Northwest Territory. It was an agreement between the Canadian Government and the Dene groups in the area in question; in return for their willingness to share their land with non-Natives, the Dene would receive medical and educational assistance, as well as treaty payments. The Canadian Government and the various Dene groups, including Yellowknives and Tłįchǫ under chief Drygeese with headmen Benaiyah and Sek'eglinan, signed the treaty in 1900 at Fort Resolution (called by the Tłįchǫ "Įndàà") . After the signing, the group that signed the treaty was called the ""Yellowknife B Band"" (Helm, 7: 1994). At that point in history, Treaty No. 8 was the largest land settlement the Canadian Government had ever made (PWNHC, Historical).
