Viceroyalty of Perú
In 1542, the Spanish created the Viceroyalty of New Castilla, that shortly afterwards would be called the Viceroyalty of Peru. In 1544, Holy Roman Emperor Charles V (King Charles I of Spain) named Blasco Núñez Vela Peru's first viceroy, but the viceroyalty was not organized until the arrival of Viceroy Francisco de Toledo in 1572.
