[Convention 169] (1989) of the ILO identifies indigenous peoples as (a) tribal peoples in countries whose social, cultural and economic conditions distinguish them from other sections of the national community, and whose status is regulated wholly or partially by their own customs or traditions or by special laws or regulations, and (b) peoples in countries who are regarded by themselves or others as indigenous on account of their descent from the populations that inhabited the country, or a geographical region to which the country belongs, at the time of conquest or colonization or the establishment of present state boundaries and who, irrespective of their legal status, retain or wish to retain, some of their own social, economic, spiritual, cultural and political characteristics and institutions.
