The Northwest

Numerous archaeological sites in the region indicate the presence—before the Spanish invasion—of permanently settled Indians who practiced irrigation and terraced farming in the oasis-like valleys. The Spanish, arriving overland from what are now Peru and Bolivia, initially occupied areas on the lowland plains of the Chaco, distant from hostile indigenous groups; they made their first permanent settlement in 1553 at Santiago del Estero. Not long afterward forts arose in the Northwest at San Miguel de Tucumán (1565), Salta (1582), San Salvador de Jujuy (1593), and San Luis (1594); Córdoba, to the south, was founded in 1573. Meanwhile, the Northwest received colonists from still farther south as Spaniards and Creole settlers from Chile founded the cities of Mendoza and San Juan in the early 1560s.

The cities in the Northwest were founded originally to support agriculture (including livestock raising) and trade with the silver mines of the Viceroyalty of Peru, particularly those at Potosí (now in Bolivia). Later, as Buenos Aires developed and the silver mines became less profitable, the country’s orientation switched to the southeast. The Spanish established a trade route between Chile and Buenos Aires that went through Córdoba and Mendoza, both of which thrived. This northward path was chosen in order to avoid the Pampas Indians, and it has remained an important transportation route. Settlement in the 600-mile- (1,000-km-) long rain shadow zone east of the Andes took place in river oases stretching from just south of San Miguel de Tucumán to San Rafael, south of Mendoza.

Rail transportation linked Mendoza to the Pampas in 1885 and sparked the development of viticulture in the Mendoza region. Access to Buenos Aires brought new capital, more settlers, better grape stock, and larger markets. Mendoza and oases such as San Rafael expanded once European immigrants could reach them and fill the labour shortage. Farmers in Tucumán province benefited from their more humid surroundings amid Andean foothills; they responded to the new markets across the Pampas by increasing sugar production, which had begun there during early colonial times. The first direct rail link between Tucumán and the Pampas in 1875 provided access to expanding sugar markets and to more modern machinery. Most of the tens of thousands of workers needed to harvest the crop came to live year-round on the large plantations, making Tucumán the most densely settled province in Argentina.
