Alexander VI

Subject of the Kingdom of Valencia (and therefore subject of the Crown of Aragon). Nephew of Callixtus III; father to both Cesare Borgia and Lucrezia Borgia. Divided the extra-European world between Spain and Portugal in the papal bull Inter caetera (1493).

Considered as one of the most controversial of the Renaissance popes, partly because he acknowledged fathering several children by his mistresses. As a result, his Italianized Valencian surname, Borgia, became a byword for libertinism and nepotism, traditionally considered as characterizing his pontificate.
