Núñez Vela, Blasco, d. 1546, first viceroy of Peru (1544-46). Sent to replace Vaca de Castro and to enforce the New Laws of Bartolomé de Las Casas, he had a violent, short career. He antagonized all in command and either ordered a murder or committed it himself. He was arrested and put on a ship for Spain, but landed at Tumbez, was defeated by Gonzalo Pizarro, and was executed.
