Origins & Early Life

The Viceroyalty of the Río de la Plata or Viceroyalty of the River Plate was the last to be organised and also the shortest-lived viceroyalty of the Spanish Empire in the Americas. It was established in 1776 from several former Viceroyalty of Peru dependencies that mainly extended over the Río de la Plata Basin, roughly the present-day territories of Argentina, northern Chile, Bolivia, Paraguay and Uruguay, extending inland from the Atlantic Coast. The colony of Spanish Guinea (present-day Equatorial Guinea) also depended administratively on the Viceroyalty of the Río de la Plata. Buenos Aires, located on the western shore of the Río de la Plata estuary flowing into the Atlantic Ocean, opposite the Portuguese outpost of Colonia del Sacramento, was chosen as the capital. Usually considered one of the late Bourbon Reforms, the organisation of this viceroyalty was motivated on both commercial grounds (Buenos Aires was by then a major spot for illegal trade), as well as on security concerns brought about by the growing interest of competing foreign powers in the area.

Career & Major Achievements

The Spanish Crown wanted to protect its territory against Great Britain and Portugal. But these Enlightenment reforms proved counterproductive, or perhaps too late, to quell the colonies' demands. The entire history of this Viceroyalty was marked by growing domestic unrest and political instability. Between 1780 and 1782, the Rebellion of Túpac Amaru II inspired a violent Aymara-led revolt across the Upper Peru highlands, demonstrating the great resentment against colonial authorities by both the mestizo and indigenous populations. Twenty-five years later, the Criollos, native-born people of Spanish descent, successfully defended against two successive British attempts to seize control of Buenos Aires and Montevideo.

Enduring Legacy & Impact

This enhanced their sense of autonomy and power at a time when Spanish troops were unable to help. In 1809, the Criollo elite revolted against colonial authorities in La Paz and Chuquisaca, establishing revolutionary governments or juntas. Although short-lived, retroversion of the sovereignty to the people provided a theoretical basis for the legitimacy of the locally based governments (temporarily in the absence of a legitimate king in Spain). These events proved decisive at the 1810 May Revolution events deposing Viceroy Cisneros at Buenos Aires. The revolution in Buenos Aires spread across the other provinces of the Viceroyalty, against the resistance of Paraguay (which declared itself an independent nation in 1811) and the Upper Peru (which was annexed by the Viceroyalty of Peru).
