The Federal Government has a unique relationship with Indian Tribes derived from the Constitution of the United States, treaties, Supreme Court doctrine, and Federal statutes. It is deeply rooted in American history, dating back to the earliest contact in which colonial governments addressed Indian Tribes as sovereign nations. The ACHP, as a federal agency, recognizes the government-to-government relationship between the United States and federally recognized Indian Tribes and acknowledges Indian Tribes as sovereign nations with inherent powers of self-governance. This relationship has been defined and clarified over time in legislation, Executive Orders, Presidential directives, and by the Supreme Court.
