Domestic dependent nations are a legal and political concept that refers to the unique relationship between the United States government and certain Native American tribes. These tribes are recognized as sovereign nations, but they are also considered dependent on the federal government for protection and certain services, making them domestic dependent nations. The term 'domestic dependent nations' was established by the Supreme Court in the 1831 case Cherokee Nation v. Georgia, which defined the relationship between the Cherokee tribe and the U.S. government. This ruling established that Native American tribes are not foreign nations, but rather domestic dependent nations that have a trust relationship with the federal government.
