History
Little is known about the origin of the Aconcagua culture, few elements of which can be ascribed to their predecessors, the Bato and Llolleo peoples, although neither is there evidence that they migrated from other latitudes. Some evidence, such as their ceramic designs, suggests that their development was influenced by groups in other regions, perhaps northwest Argentina or the Bolivian Altiplano. When the Inka arrived in the 15th Century, the Aconcagua people adopted many cultural elements from both the Inka and the Diaguita, the latter being a culture from further north that expanded into this part of Chile through their association with the Inka Empire of Tawantinsuyu.
