After the Spanish conquest of Peru (1532–37), the first Audiencia was constituted by Lope García de Castro (1516–1576), a Spanish colonial administrator who served as a member of the Council of the Indies and of the Audiencias of Panama and Lima. From September 2, 1564, to November 26, 1569, he was interim viceroy of Peru. In 1542, the Spanish created the Viceroyalty of New Castile, which shortly afterward 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 Álvarez de Toledo, who made an extensive tour of inspection of the colony.
