Population Currents
Since the 16th. Century until 1810 there were three population currents on the Argentine territory, namely:
Eastern Population current: it came directly from Spain, arriving through the Río de la Plata and Paraná rivers. It founded the cities of Buenos Aires, Asunción del Paraguay, Santa Fe, Corrientes and Paraná.
Northern Population Current : it descended from Perú and came across the Humahuaca Plateau founding the cities of: Santiago del Estero, San Miguel de Tucumán, Córdoba, Salta, San Fernando del Valle de Catamarca, La Rioja and San Salvador de Jujuy. It was characterized by an urban and cultural development with population settlements accompanied by an economic growth.
Western Population Current : it arrived from Chile and founded the cities of Mendoza, San Juan and San Luis. In 1700 there were around 2,500 Europeans in the Viceroyalty of the Río de la Plata. By 1810 there were scarcely 6,000, over a total population of 700,000 inhabitants in the present national territory. Unlike the conquering process developed by the British in the United States of America, based on the settlement of agricultural colonies, the Spanish colonisers tended to develop urban settlements and left large areas with no occupation such as Chaco, Patagonia and La Pampa, what decisively determined the future demographic development.
