Throughout history, different states designate the groups within their boundaries that are recognized as indigenous peoples according to international or national legislation by different terms. Indigenous people also include people indigenous based on their descent from populations that inhabited the country when non-indigenous religions and cultures arrived—or at the establishment of present state boundaries—who retain some or all of their own social, economic, cultural and political institutions, but who may have been displaced from their traditional domains or who may have resettled outside their ancestral domains.
