The Viceroyalty of Peru was a major administrative division of the Spanish Empire in South America, established in the early 16th century. It served as a critical center for Spanish colonial rule, covering a vast territory that included modern-day Peru, Ecuador, Bolivia, and parts of Chile and Argentina. This viceroyalty was significant in the context of Spanish conquest, as it facilitated the exploitation of resources and the establishment of colonial governance, connecting directly to the activities of Spanish conquistadors.
