Viceroyalty of the Río de la Plata The Viceroyalty of the Río de la Plata (Spanish: "Virreinato del Río de la Plata" ) was the last to be organized and also the shortest-lived of the Viceroyalties of the Spanish Empire in the Americas.
Real Audiencia of Charcas The Real Audiencia of Charcas (Spanish: "Audiencia y Cancillería Real de La Plata de los Charcas" ) was a Spanish "audiencia" with its seat in what is today Bolivia. It was established in 1559 in Ciudad de la Plata de Nuevo Toledo (later Charcas, today Sucre) and had jurisdiction over Charcas, Paraguay and the Governorate of the Río de la Plata, today Uruguay and northern Argentina. This court oversaw the incredible silver output of the mines at Potosí. It was part of the Viceroyalty of Peru until 1776, when it was transferred to the newly created Viceroyalty of the Río de la Plata and began to be referred to as Upper Peru.
