The Tsetsaut (also known as the Wetaɬ) were a Dene people who lived inland from the Tlingit (Łingít) along the western coast of British Columbia and Southeastern Alaska. Apart from Nisga’a oral tradition and the linguistic research of anthropologist Franz Boas, who lived among the Tsetsaut in the 1890s, little is known about them. The Tsetsaut were decimated by war and disease in the 1800s, their numbers reduced to just 12 by the end of the century. It was once believed that the last of the Tsetsaut people died in 1927 and that their ancient language was no longer spoken. However, as of 2019, there are approximately 30 people from the Tsetsaut/Skii km Lax Ha Nation identifying as Tsetsaut in British Columbia.
