Last years

A danger now arose in the shape of a conspiracy by the deposed despots, the Orsini, and of some of Cesare's own condottieri. At first, the papal troops were defeated and things looked bleak for the house of Borgia. But a promise of French help quickly forced the confederates to come to terms. Cesare, by an act of treachery, then seized the ringleaders at Senigallia and put Oliverotto da Fermo and Vitellozzo Vitelli to death (31 December 1502). When Alexander VI heard the news, he lured Cardinal Orsini to the Vatican and cast him into a dungeon, where he died. His goods were confiscated and many other members of the clan in Rome were arrested, while Alexander's son Goffredo Borgia led an expedition into the Campagna and seized their castles. Thus the two great houses of Orsini and Colonna, who had long fought for predominance in Rome and often flouted the pope's authority, were subjugated and the Borgias' power increased. Cesare then returned to Rome, where his father asked him to assist Goffredo in reducing the last Orsini strongholds; this he was unwilling to do, much to his father's annoyance; but he eventually marched out, captured Ceri and made peace with Giulio Orsini, who surrendered Bracciano.

The war between France and Spain for the possession of Naples dragged on, and the pope was forever intriguing, ready to ally himself with whichever power promised the most advantageous terms at any moment. He offered to help Louis XII on condition that Sicily be given to Cesare, and then offered to help Spain in exchange for Siena, Pisa and Bologna.
