Indian Land Claims Settlements

Indian Land Claims Settlements are settlements of Native American land claims by the United States Congress, codified in 25 U.S.C. ch. 19. 
In several instances, these settlements ended live claims of aboriginal title in the United States. The first two—the Rhode Island Claims Settlement Act and the Maine Indian Claims Settlement Act—extinguished all aboriginal title in Rhode Island and Maine, respectively, following initial court rulings in the tribes' favor. 
The Mohegan Nation (Connecticut) Land Claims Settlement of 1994 also followed a judicial ruling in favor of a tribe, but did not extinguish all aboriginal title in the state. Other tribes had pending land claims.
The "Passamaquoddy" (1975), "Narragansett I and II" (1976), and "Mohegan" (1980, 1982) cases occurred in the U.S. Supreme Court's "Oneida I" (1974) decision, which held that there was federal subject-matter jurisdiction for such claims.
The Florida Indian (Miccosukee) Land Claims Settlement and Florida Indian (Seminole) Land Claims Settlement relate to water rights in the Everglades.
In Canada, these settlements involve First Nations.
