Between 1878 and 1884 the so-called Conquest of the Desert occurred, with the purpose of giving by means of the constant confrontations between natives and Criollos in the border, and the appropriation of the indigenous territories, tripling the Argentine territory. The first conquest, consisted of a series of military incursions into the Pampa and Patagonian territories dominated by the indigenous peoples, distributing them among the members of the ''Sociedad Rural Argentina'', financiers of the expeditions. The conquest of Chaco lasted up to the end of the century, since its full ownership of the national economic system only took place when the mere extraction of wood and tannin was replaced by the production of cotton. The Argentine government considered indigenous people as inferior beings, without the same rights as Criollos and Europeans.
