Francisco de Carvajal was a Spanish military officer, conquistador, and explorer remembered as "the demon of the Andes" due to his brutality and uncanny military skill in the Peruvian civil wars of the 16th century.

Gonzalo Pizarro y Alonso was a Spanish conquistador. He was the younger paternal half brother of Francisco Pizarro, who led the Spanish conquest of the Inca Empire. Pizarro was the illegitimate son of Gonzalo Pizarro y Rodríguez de Aguilar (1446–1522), who, as an infantry colonel, served under Gonzalo Fernández de Córdoba during the Italian Wars. He was also the younger paternal half brother of Hernándo Pizarro y de Vargas and the older paternal full brother of Juan Pizarro y Alonso.
