Treaty 6 is the sixth of the numbered treaties that were signed by the Canadian Crown and various First Nations between 1871 and 1877. It is one of a total of 11 numbered treaties signed between the Canadian Crown and First Nations. Specifically, Treaty 6 is an agreement between the Crown and the Plains and Woods Cree, Assiniboine, and other band governments at Fort Carlton and Fort Pitt. Key figures, representing the Crown, involved in the negotiations were Alexander Morris, Lieutenant Governor of Manitoba and The North-West Territories; James McKay, The Minister of Agriculture for Manitoba; and William J. Christie, a chief factor of the Hudson's Bay Company. Chief Mistawasis and Chief Ahtahkakoop represented the Carlton Cree.
Treaty 6 included terms that had not been incorporated into Treaties 1 to 5, including a medicine chest at the house of the Indian agent on the reserve, protection from famine and pestilence, more agricultural implements, and on-reserve education. The area agreed upon by the Plains and Woods Cree represents most of the central area of the current provinces of Saskatchewan and Alberta.
