fact that "Indian" arose from a historical error, and does not accurately reflect the origin of the people to whom it refers. In addition, some feel that the term has so absorbed negative and demeaning connotations through its historical usage as to render it objectionable in context. Additionally, "American Indian" is often understood to mean only the peoples of the mainland body of the United States, which excludes other peoples considered Indigenous peoples of the Americas; including the Haida, Tlingit, Athabascan, Inuit, Yup'ik (Yuits/Alutiiq/Cup'ik), Iñupiat, Aleut (i.e., the groups whose traditional languages are Eskimo–Aleut languages), Marshallese, and Samoan. Related groups among these tribal peoples are referred to collectively as either Alaskan Natives (based on geography), First Nations (in Canada), Native Hawaiians, or Siberians. Supporters of the terms "Indian" and "American Indian" argue that they have been in use for such a long period of time that many people have become accustomed to them and no longer consider them exonyms. Both terms are still widely used today. "American Indian" appears often in treaties between the United States and the Indigenous peoples with whom they have been negotiating since the colonial period, and many federal, state and local laws also use it. "American Indian" is the term used in the United States Census.

One early use is the 1817 novel Keep Cool by John Neal, which declares "the Indian is the only native American; he holds his charter from God himself". During the 1850s, a group of Anglo-Saxon Protestant Americans used the capitalized term Native Americans to differentiate themselves from recent Irish and German immigrants, both of which groups were predominantly Catholic. The group later formed the "Know-Nothings", a 19th-century political party that opposed immigration to the United States, a policy known as nativism. The Know-Nothings also called themselves the "Native American Party" and were referred to in the press with the capitalized term. In 1918, leaders of the Indigenous Peyote Religion incorporated as the Native American Church of Oklahoma. In 1956, British writer Aldous Huxley wrote to thank a correspondent for "your most interesting letter about the Native American churchmen". The use of Native American or native American to
