What did native Americans gain during the 1970 and 1980 as a result of legal victories?

During the 1970s and 1980s, Native Americans achieved significant legal victories that led to increased recognition of their rights and sovereignty. Landmark court cases, such as the 1974 decision in United States v. Wheeler, affirmed tribal sovereignty and self-governance. Additionally, the Indian Self-Determination and Education Assistance Act of 1975 enabled tribes to manage federal programs and services, fostering greater autonomy. These developments contributed to a resurgence of cultural identity and empowerment within Native American communities.
