Lucrezia Borgia (1480 – 1519) was the illegitimate daughter of Rodrigo Borgia, and the younger sister of Cesare Borgia. She was a member of the Templar Order, and later became the Duchess of Ferrara. During her lifetime, Lucrezia was ruthlessly betrothed by her father twice before her thirteenth birthday, in order to secure political alliances. She was also rumored to have been sexually abused by her father and brothers.
