Métis [SEP] Introduction
The Métis (; ) are a multi ancestral indigenous group whose homeland is in Canada and parts of the United States between the Great Lakes region and the Rocky Mountains. The Métis trace their descent to both Indigenous North Americans and European settlers. Not all people of mixed Indigenous and Settler descent are Métis, as the Métis are a distinct group of people with a distinct culture and language.
