Giordano Loffredo Caetani by his marriage with Giovanna dell'Aquila, heiress of the counts of Fondi and Traetto, in 1297 added the name of Aquila to his own, and his grandson Giacomo acquired the lordships of Piedimonte and Gioia. The Caetani proved brave warriors and formed a bodyguard to protect Boniface VIII from his many foes. During the 14th and 15th centuries their feuds with the Colonna caused frequent disturbances in Rome and the Campagna, sometimes amounting to civil war. They also played an important role as Neapolitan nobles: in particular, Onorato I Caetani was a powerful baron in what is now southern Lazio and one of the main supporters of Antipopes Clement VII and Benedict XIII. In 1500 Pope Alexander VI, in his attempt to crush the great Roman feudal nobility, confiscated the Caetani fiefs and gave them to his daughter Lucrezia Borgia; but they afterwards regained them.
