In celebration of Native American History Month, we have just added 428 Native American documents containing constitutions, charters, and acts from the years 1830 to 1960 to Law.gov. The collection contains two types of material: constitutions from the 1800s produced by the Cherokee, Choctaw, Chickasaw, and Creek; and constitutions and charters drafted after the 1934 Indian Reorganization Act. The latter includes laws produced by the Office of Indian Affairs of the United States Department of the Interior. These materials are divided by region based on the new KI class designations: Arctic-Alaska, US-Northeast Atlantic, US-North Central, US-New Southwest, US-Pacific Northwest, and US-South.
