Treaty 7 is an agreement between the Canadian government and several, mainly Blackfoot, First Nation band governments in what is today Southern Alberta. The idea of developing treaties for Blackfoot lands was suggested to Blackfoot Chief Crowfoot in 1875. Negotiations were concluded two years later and on September 22, 1877, the agreement was signed at the present-day Siksika Nation reserve, east of Calgary. Chief Crowfoot was one of the signatories to Treaty 7.
