Cesare Borgia, son of Pope Alexander VI, becomes the first person in history to resign the cardinalate; later that same day, King Louis XII of France names him Duke of Valentinois.
Cesare Borgia (Italian pronunciation: [ˈtʃeːzare ˈbɔrdʒa, ˈtʃɛː-]; Valencian: Cèsar Borja [ˈsɛzaɾ ˈbɔɾdʒa]; Spanish: César Borja [ˈθesaɾ ˈβoɾxa]; 13 September 1475 – 12 March 1507) was an Italian cardinal and condottiero (mercenary leader) of Aragonese (Spanish) origin, whose fight for power was a major inspiration for The Prince by Niccolò Machiavelli. He was an illegitimate son of Pope Alexander VI and member of the Spanish-Aragonese House of Borgia.After initially entering the church and becoming a cardinal on his father's election to the Papacy, he became, after the death of his brother in 1498, the first person to resign a cardinalate. He served as a condottiero for King Louis XII of France around 1500, and occupied Milan and Naples during the Italian Wars. At the same time he carved out a state for himself in Central Italy, but after his father's death he was unable to retain power for long. According to Machiavelli, this was not due to a lack of foresight, but his error in creating a new pope.
