1776 CE
Spain, acting on security concerns over the increasing interest of other world powers on the area, mainly the Kingdom of Portugal and the Kingdom of Great Britain, carves from the Viceroyalty of Peru in 1776 a new polity, the Viceroyalty of the Río de la Plata (including present Argentina, Uruguay, Paraguay and southern Bolivia), with its capital in Buenos Aires. (The Spanish name, Virreinato del Río de la Plata, translates literally to Viceroyalty of the River of Silver, although some sources conventionally call the new entity Viceroyalty of the River Plate.)
