After his unheard claims as governor of New Castile (Peru) following the death of his brother, Gonzalo Pizarro pressed claims to be recognized as the ruler of the land he and his brothers had conquered. After the arrival of appointed royal viceroy Blasco Núñez Vela in 1544, Gonzalo succeeded to have him repelled and sent to Panama in chains. He was released, however, and returned to Peru by sea while Gonzalo was mustering an army. The two met on January 18 at Añaquito in the outskirts of Quito, present-day capital of Ecuador, where the superiority of the Nueva Castilla army ensured victory for Gonzalo. Blasco Núñez Vela reportedly fought bravely but fell as a victim in battle and was later decapitated on the field of defeat, a fate Gonzalo himself would share two years later at Jaquijahuana.
