History of Argentina: From the Arrival of the Spanish to the 20th Century

Human presence in what is now Argentina dates back approximately 13,000 years, with evidence of early settlements in Patagonia. Archaeological findings suggest human activity through the Paleolithic, Mesolithic, and Neolithic periods. However, a significant depopulation of large interior areas occurred between 4000 and 2000 B.C., likely due to a prolonged period of drought. Over time, indigenous peoples in the region evolved into diverse cultural groups with varying levels of complexity.

Uruguayan archaeologist Raúl Campá Soler categorized Argentina’s indigenous peoples into three groups: basic hunters and food gatherers without pottery; advanced gatherers and hunters; and basic farmers who developed pottery. The Pampas and Patagonia were dominated by the first group, while the second included tribes like the Charrúa, Minuane, and Guaraní. The third group, inhabiting regions such as the Quebrada de Humahuaca, adopted farming practices and pottery.
