Native American cultural traditions
Nez Pierce tribal traditions are preserved at Montana's Big Hole National Battlefield.
The Native American Graves Protection and Repatriation Act (NAGPRA) formally affirms the rights of lineal descendants, Indian tribes, and Native Hawaiian organizations to custody of Native American human remains, funerary objects, sacred objects, and objects of cultural patrimony. In enacting this legislation, Congress and the President acknowledged that over the course of the nation's history, Native American human remains and funerary objects have suffered from differential treatment as compared with the human remains and funerary objects of other groups. They also acknowledged that the loss of sacred objects by Indian tribes and Native Hawaiian organizations has negatively impacted Native American religious practices. They further acknowledged the failure of American law to recognize concepts of communal property that were traditionally and still are in use by some Indian tribes.
