Pedro Sánchez de la Hoz

Pedro Sánchez de la Hoz (Calahorra, La Rioja, 1514 - Santiago de Chile, 1547) was a Spanish merchant, conquistador and adelantado. In 1534 he obtained the rights of a capitulación south of the Straits of Magellan. Sánchez de la Hoz had a conflictive relation with rival conquistador Pedro de Valdivia. In 1547 Francisco de Villagra, one of Valdivia's men, had Sánchez de la Hoz executed.

According to Argentina and Chile the capitulación granted to Sánchez de la Hoz proves the Spanish Empire had claims and an animus occupandi on the lands that would later be called Antarctica. Given that Chile and Argentina have historically successfully established their border based on the uti possidetis iuris principle of international law the Sánchez de la Hoz grant forms part of their arguments for territorial claims in Antarctica.
