In 1870, Canada acquired the Hudson's Bay Company's territories and formed the North-West Territories to administer the vast territory between British Columbia and Manitoba. The Crown also entered into a series of numbered treaties with the indigenous peoples of the area, which serve as the basis of the relationship between First Nations, as they are called today, and the Crown. Since the late twentieth century, land losses and inequities as a result of those treaties have been subject to negotiation for settlement between the First Nations in Saskatchewan and the federal government, in collaboration with provincial governments.
