Pier Luigi de Borgia, 1st Duke of Gandía

He was the first duke of Gandía, a duchy in the Kingdom of Valencia that King Ferdinand II of Aragon re-established in 1485 as a favour to his father.

In the bull of his legitimation, on 5 November 5 1481, Sixtus IV speaks of him as Adolescente Romano, declaring him to be the son of Cardinal-Deacon Rodrigo Borgia and a freewoman (de tune Diacono Cardinali et soluta).

Through this agreement, Pier Luigi was required to provide the marquis an unknown sum, albeit considered small, and accept certain rights pertaining to the crown and of Valencia over the lands of the duchy.

In late 1485, King Ferdinand II officially elevated Pier Luigi's status to Duke of Gandía.

[4] In his will, Pier Luigi ceded the duchy to his younger brother Giovanni and left a dowry of 10,000 florins to his sister, Lucrezia.
