Governorate of New Castile
The Governorate of New Castile (Gobernación de Nueva Castilla, pronounced [ɡoβeɾnaˈθjon de ˈnweβa kasˈtiʎa]) was the gubernatorial region administered to Francisco Pizarro in 1529 by King Charles I of Spain, of which he was appointed governor via a capitulation. The region roughly consisted of modern Peru and was, after the foundation of Lima in 1535, divided.
