Native American Languages Act

The Native American Languages Act of 1990 (NALA) is a US statute that gives historical importance as repudiating past policies of eradicating indigenous languages of the Americas by declaring as policy that Native Americans were entitled to use their own languages. The fundamental basis of the policy's declaration was that the United States "declares to preserve, protect and promote the rights and freedom of Native Americans to use practice and develop Native American Languages".
