The first meeting of the United Nations Working Group on Indigenous Populations was on 9 August 1982 and this date is now celebrated as the International Day of the World's Indigenous Peoples. In 1982 the United Nations Working Group on Indigenous Populations (WGIP) accepted as a preliminary definition a formulation put forward by Mr. José R. Martínez-Cobo, Special Rapporteur on Discrimination against Indigenous Populations. This definition has some limitations, because the definition applies mainly to pre-colonial populations, and would likely exclude other isolated or marginal societies. Indigenous communities, peoples, and nations are those that, having a historical continuity with pre-invasion and pre-colonial societies that developed on their territories, consider themselves distinct from other sectors of the societies now prevailing in those territories, or parts of them.
