The Indian Self-Determination Movement refers to a political effort by Native American tribes and communities to assert their right to self-governance, autonomy, and control over their own affairs. This movement gained significant momentum in the 1960s and 1970s as Indigenous peoples sought to reclaim their rights, challenge federal policies, and promote cultural revitalization. It is closely connected to broader discussions on tribal jurisdiction and legal sovereignty, highlighting the need for tribes to manage their own resources and legal systems without external interference.
