This profile offers an excellent overview of Oglala Sioux law, both traditional and modern. Like many tribes, the Indian Reorganization Act had a major impact on the contemporary law of the Oglala Sioux. While the IRA resulted in tribal constitutions that reflected the values of the U.S. Constitution, this profile examines the traditional and customary law that was subsequently incorporated into the Oglala Sioux Constitution. This profile includes a brief history of the Oglala Sioux, overview of traditional law, governmental structure, summary of contemporary law, and history of political activism.
