Upper Peru (Spanish: Alto Perú; Portuguese: Alto Peru) is a name for the land that was governed by the Real Audiencia of Charcas.[1] The name originated in Buenos Aires[2] towards the end of the 18th century[3] after the Audiencia of Charcas was transferred from the Viceroyalty of Peru to the Viceroyalty of the Río de la Plata in 1776.[4] It comprised the governorships of Potosí, La Paz, Cochabamba, Chiquitos, Moxos and Charcas (since renamed Sucre).
