Mistawasis is a Cree name meaning "big child", derived from mistahi ("big, great") and awâsis ("child"). This name was borne by a prominent 19th-century Chief of the Sak-kaw-wen-o-wak Plains Cree, also known in English as Pierre Belanger. Mistawasis is best remembered for his role as a key leader during the signing of Treaty 6 in 1876, where he was the first signatory. Facing the decline of the buffalo herds due to overhunting, he recognized the need for a new strategy to ensure his people's survival and advocated for negotiation with the Canadian government. Historical Significance Alongside his close ally, Chief Ahtahkakoop, Mistawasis used his influence among the Cree to achieve consensus in favor of Treaty 6's adoption. The terms of Treaty 6 established reserves, including the Mistawasis First Nation in Saskatchewan, which bears his name where he met government officials. After the treaty, he maintained allegiance to the Crown until his death. Cultural Context The name reflects Cree linguistic elements associated with size and respect. "Mistah" conveys greatness. This remains a surname for many Cree traced to his lineage. There is also the late Plains Cree elder, John Mistawasis, who narrated a tragic story of marriage between two chiefs' children. Spellings like Mistowasis also exist. Meaning: "Big child" Origin: Cree Type: First name Usage regions: Indigenous (Plains Cree), Canada
