Answer: The written treaty ceded roughly 130,000 km² of land from the Rocky Mountains to the west, the Cypress Hills to the east, the Red Deer River to the north, and the US border to the south. All nations kept the rights to use the land for hunting.
Treaty 7 is the last of the Numbered Treaties made between the Government of Canada and the Plains First Nations (see Indigenous Peoples: Plains). It was signed on 22 September 1877 by five First Nations: the Siksika (Blackfoot), Kainai (Blood), Piikani (Peigan), Stoney-Nakoda, and Tsuut’ina (Sarcee). Different understandings of the treaty’s purpose, combined with significant culture and language barriers and what some have argued were deliberate attempts to mislead the First Nations on the part of the government negotiators, have led to ongoing conflicts and claims.
