Sancho Pedro: - Pedro Sánchez de la Hoz, sometimes known as Pedro Sancho de la Hoz, was a Spanish merchant, conqueror, and adelantado who worked as Pizarro's secretary from 1514 to 1547. He received the rights to a capitulación de conquista [es] south of the Magellan Straits in 1534. In 1539, Charles V, Holy Roman Emperor, appointed him as an adelantado of the Governorate of Terra Australis. Sánchez de la Hoz was Pizarro's secretary in Peru during the conquest of Cuzco, and he penned an account of the conquest of Peru. While the original manuscript was lost, an Italian translation of the work was saved and has since been translated into various languages, serving as a valuable account of both the Spanish invasion and Incan ethnography. He returned to Spain after some financial success and was granted permission by Emperor Charles V to return to the New World, where he clashed with rival conqueror Pedro de Valdivia over several grants to regions south of Peru. Sánchez de la Hoz was executed for spearheading a rebellion in 1547 by Francisco de Villagra, one of Valdivia's men. According to Argentina and Chile, Sánchez de la Hoz's capitulación demonstrates the Spanish Empire had claims and an animus occupandi on the areas that would later be known as Antarctica.
