Federal Indian law (FIL), also known as American Indian law, is the body of doctrine that regulates the political relationship between American Indian and Alaska Native governments and the federal government. FIL is best understood as the development of this “government-to-government” relationship, which intersects with other bodies of law like constitutional law, criminal law, and environmental law. FIL is comprised of legal doctrines, statutes, judicial decisions, treaties, and executive orders, all of which have direct influences on the rights and sovereignty of Indian tribes. In the United States there are 573 federally recognized tribes that are subject to the rights and privileges, as well as the consequences, of FIL. These federally recognized tribes are the third sovereign authority in the United States—the other two are states and the federal government—that retain inherent rights and that exercise and enjoy sovereignty and self-governance on their own lands. The historical development of FIL in the United States constitutes an important starting point in understanding the special relationship between Indian tribes and the federal government. The origins of FIL lay in three US Supreme Court cases known as the “Marshall trilogy,” after Chief Justice John Marshall, the presiding chief justice of Johnson v. McIntosh (1823), Cherokee Nation v. Georgia (1831), and Worcester v. Georgia (1832). At that time, the primary questions centered on the sovereign rights of Indian tribes, that is, whether Indians have dominion over themselves and their lands. Throughout the development of FIL, until today, questions of Indian tribal sovereignty—or Indigenous nation sovereignty—remained contentious as Indians continued to fight for treaty rights, autonomy, and self-determination. FIL can be described as a series of wins and losses for American Indians in their fight for sovereign rights. In the end, however, the study of FIL is equally the study of how the United States was able to legally subjugate America’s indigenous peoples and acquire their lands. FIL is basically the study of America’s justification for Native America’s colonization and the genocide perpetrated against American Indians. The literature on FIL or American Indian law is vast, but the most valuable resources are authored by and for attorneys and for students of law. Although the disciplines of Native American and Indigenous studies encompass facets of American Indian and Indigenous peoples’ lives, scholarship in FIL has proven to be beneficial. The resources cited in this article represent some of the widely used texts that provide a solid foundation for studies in FIL.
