Conquest and Colonization of the Río de la Plata

The conquest and colonization of the Río de la Plata relates to the discovery, conquest and colonization of the current Argentine territory, by the Spanish empire. Until then our territory was inhabited by sparse indigenous population, composed mostly of nomadic aborigines.

The issue that we will discuss here, refers to the historical period, covered since the discovery of America by Christopher Columbus in 1492; the foundation of the fort Sancti Spiritu by Sebastian Cabot in 1527; the first and second foundation of Buenos Aires by Pedro de Mendoza (1534) and Juan de Garay (1580) respectively; the foundation of the Viceroyalty of the Río de la Plata in 1776; to the defense of Buenos Aires from British invasions of 1806 and 1807 by the natives who begin to write their own history.

When Settlers came to South

After the first travels by Columbus, in 1492, there were new expeditions. One of them, led by Amerigo Vespucci, in 1502, was responsible for the Spaniards first encounter with the lands which would later become the Argentine territory. By that time, this area of the south was inhabited by different groups of indigenous peoples, who were mostly nomadic.
A short time afterwards, in 1516, in a failed attempt to find a passage connecting the Atlantic Ocean to the Pacific Ocean, Juan Díaz de Solís had to end his expedition near the sandbanks of Plata River. It was in these lands that Solís found his death by the Indians. Sebastián Gaboto, his successor, arrived with a new expedition sent by the Spanish King, Charles V.

Gaboto established the first Spanish settlement, Fort Sancti Spiritu, in 1527.
In 1536, the conquest and colonization of the Río de la Plata, was left in the hands of Pedro de Mendoza, thanks to an agreement signed with Charles V. Two years later, Nuestra Señora del Buen Ayre was founded in the canyons of Río de la Plata (Plata River).
After Mendoza’s death in the sea, while returning to Spain, and the dismantlement of Nuestra Señora del Buen Ayre by the Indians, the Spanish Capital was moved in 1541 to Asuncion, Paraguay.

Foundation of Buenos Aires

The definitive founding of Buenos Aires took place in 1580, by Juan de Garay, who in turn colonized most of the Argentine territory.
The governorship was divided into two intendances in 1617, Asunción and Buenos Aires. From then on, different governors succeeded and the missionary activity became stronger. The rivalry between Spain and Portugal about the American colonies increased.

English Invasions

Meanwhile, after the establishment of the Virreinato del Río de la Plata in 1776, these lands began to stand out as a political and economic unit of some relevance, a fact which did not pass unnoticed for British eyes. Furthermore, the decline of the Spanish empire brought about the attempted invasions by England in 1806 and 1807. Nevertheless, the sudden English attack ended in failure thanks to the strong resistance by the natives, who had begun to feel that these lands were their own.
