The seeds of the organization were planted when Chiefs and leaders gathered in Fort Qu’Appelle in 1946, emerging with an organization to advocate for the rights of First Nations people — the Union of Saskatchewan Indians.
In 1958, the First Nations leaders gathered in Fort Qu’Appelle and reviewed the constitution of the Union, replacing it with a new organization that more fairly represented the First Nations reality. It was decided that the organization be looked upon as a federation of bands and that the power reside in the hands of the Chiefs. The Union evolved into the Federation of Saskatchewan Indians.
In April 1982, the First Nations signed the Federation of Saskatchewan Indian Nations Convention and agreed to unite in a common front to protect and preserve First Nations’ Treaty rights and their political, economic, social and cultural characteristics. The political convention outlined a governing structure that consisted of the Chiefs-in-Assembly, a Senate, an Elders’ Council, an Executive Council and an Indian Government Commission.
