Pandolfo Petrucci

When the Noveschi returned to prominence, Petrucci seized power in a coup,[3] with the support of Cardinal Piccolomini, nephew of Pope Pius II, and assistance from his brother Giacopo (d. 1497).

With his father-in-law's backing, Petrucci assumed a number of public offices and gained a vast amount of political power.

However, Petrucci's power and his organization of followers in Siena's government gained him many enemies, including his father-in-law.

Although a brutal authoritarian and absolutist, Petrucci was careful to pacify the people of Siena by improving the city's economy and encouraging the advancement of art.

[2] When France and Spain invaded the Italian Peninsula, Petrucci became involved in a number of political intrigues.

Petrucci suspected his life was in danger and avoided the meeting, but nevertheless fled Siena in January 1503 in order to appease Borgia.

However, Pope Julius II and Spain forced Petrucci to make peace with Florence, to which he reluctantly gave the territory of Montepulciano in 1512.
