Rise and Fall of Viceroyalty of the Río de la Plata
Also know as Viceroyalty of the Provinces of the Río de la Plata, was created by the Spanish Crown in the Americas and was part of the Empire of Spain. The reform Bourbon, which refers to the appointment of Felipe V de Borón as successor of Carlos II by himself a month before his death, gave rise to the creation provisional of this viceroyalty on August 1, 1776, until a year later King Carlos III officially ordered it, based on a suggestion by José de Gálvez y Gallardo, his minister of the Indies, and decided that the city of Buenos Aires was its capital
The emergence of the Viceroyalty of the Río de la Plata took advantage of the break produced in the viceroyalty of Peru and covered Buenos Aires, Tucumán and Santa Cruz de la Sierra, Paraguay and the districts of Charcas and Cuyo (belonging to the General Captaincy of Chile), among other territories. Today, these governorates are part of Uruguay, Argentina, Bolivia, Paraguay and a portion of southern Brazil, southeastern Peru, northern Chile and the Falkland Islands themselves.
On the other hand, history tells us that the African islands Annobón and Fernando Poo (which are currently in Equatorial Guinea) were also part of the dominions of the viceroyalty, although only in theory; the colonization of these lands by the Spanish government was not successful.
The Viceroyalty of the Río de la Plata began to write its last lines when, between the triumph of the May Revolution of 1810 in the city of Buenos Aires, Argentina began the War of Independence, a fact that caused the dismantling of the Viceroyalty and ended up dividing it. Francisco Javier de Elío, known as the last viceroy, left the power on November 18, 1811, giving the command to Gaspar de Vigodet, who until then had ruled Montevideo. Three more years were enough for the Second Site of Montevideo to overthrow Spanish power in the Río de la Plata.
