Argentina's history is a rich tapestry that can be divided into four distinct periods: the pre-Columbian or early history (up to the sixteenth century), the colonial period (1530–1810), the nation-building period (1810–1880), and contemporary history (from approximately 1880 to the present). Each phase shaped the region, transforming it from sparsely inhabited land into the modern Argentine Republic.
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.
