Input: Question: Of the king Duchy sided against and the man who defeated Duchy, which one was born first? Passage:Nicolò's son Piergiampaolo inherited Sora and Alvito, while another son, Piergiovanni, inherited Popoli. Piergiampaolo soon annexed his brother's Abruzzese lands and, after siding against the new king, Ferdinand I, in the revolt of 1460, captured the territories of Montecassino, Arce, and the fiefs of the Colonna in Abruzzo. He also took part in the sieges of Sulmona and L'Aquila, but was in turn besieged and defeated by Napoleone Orsini at Sora. As a result, he was forced to cede Sora, Arpino, Casalvieri, Isola del Liri, and Fontana Liri to the Papal States in 1463. His duchy was downgraded to a county, the title being assigned to Piergiovanni. At the same time, Alvito and Sora were given the right to mint cavalli (a type of coin). Piergiampaolo organized a second plot against Ferdinand, but was again defeated and had to abandon hopes in returning to Alvito. Exiled to France, he returned with the invading army of Charles VIII of France during the War of 1494–95. With his brother, Sigismondo II of Sora, he re-conquered most of his lands. He was able to resist the Neapolitans after the French retreat, but in 1496 Sora fell to Frederick I of Naples, followed in 1496 by Alvito, captured by general Gonzalo de Córdoba. This put an end to the Cantelmo rule.
