The term Kwakiutl was usually applie to a group of indigenous peoples of northern Vancouver Island, Queen Charlotte Strait and the Johnstone Strait, who are now known as Kwakwaka'wakw, which means Kwak'wala-speaking-peoples. The term, created by anthropologist Franz Boas, was used up until the 1980's. It comes from one of the Kwakwaka'wakw tribes, the Kwagu'ł, at Fort Rupert, whom Franz Boas did most of his anthropological work and whose Indian Act band government is the Kwakiutl First Nation. The term was also misapplied to mean all the tribes who spoke Kwak'wala, as well as three other indigenous peoples who language is apart of the Wakashan linguistically group, but whose language is not Kwak'wala. These peoples, incorrectly known as the Northern Kwakiutl, were the Haisla, Wuikinuxv, and Heiltsuk.
