The Indian Civil Rights Act of 1968 is a U.S. law that protects the civil rights of individuals belonging to Native American tribes. It aims to ensure that tribal governments uphold certain rights, such as freedom of speech, religion, and due process, similar to those guaranteed by the U.S. Constitution. This act also addresses issues like discrimination and provides a framework for individuals to seek legal recourse if their rights are violated within tribal jurisdictions. It represents a significant step towards recognizing and safeguarding the rights of Native Americans in the context of their own governments.
