What was the capital of the union of provinces in the Río de la Plata comprised by most of the former dependencies from the last to be organized and also the shortest-lived of the Viceroyalties of the Spanish Empire in the Americas?
United Provinces of the Rio de la Plata The United Provinces of the Río de la Plata (Spanish: "Provincias Unidas del Río de la Plata" ), earlier known as the United Provinces of South America (Spanish: "Provincias Unidas de Sudamérica" ), a union of provinces in the Río de la Plata region of South America, emerged from the May Revolution in 1810 and the Argentine War of Independence of 1810–1818. It comprised most of the former Viceroyalty of the Río de la Plata dependencies and had Buenos Aires as its capital.
Battle of Cuzco The Battle of Cuzco was fought in 1533 between the forces of Spain and of the Incas. After executing the Inca Atahualpa, Francisco Pizarro marched his forces to Cuzco, the capital of the Incan Empire. As the Spanish army approached Cuzco, however, Pizarro sent his brother Juan Pizarro and Hernando de Soto ahead with forty men. The advance guard fought a pitched battle with Incan troops in front of the city, securing victory. The Incan army under the command of Quizquiz withdrew during the night. The Spanish plundered Cuzco, where they found much gold and silver. Quizquiz was eventually killed, after being struck down by his own followers, leaving none to lead the Inca Empire, since his only equal commander Chalkuchimac had been burned in captivity.
