Pandolfo Petrucci

Pandolfo Petrucci (1452–1512) was the effective lord of Renaissance Siena. His family was exiled in 1456 after his uncle's failed plot and returned only in 1480. As captain of the city guard from 1495 he built his power, and after his brother's death in 1497 he eliminated his rivals, having his father-in-law killed in 1500, and ruled Siena as its undisputed master.

After plotting against Cesare Borgia he fled in 1503 and returned under French protection. In 1512 he ceded Montepulciano to Florence before dying, leaving Siena to his son Borghese.
