Along with Constantine's cavalry, Francesco del Balzo, the Duke of Andria who had remained loyal to Ferdinand, managed to defeat Ercole d'Este, one of the pro-Angevin nobles in Gargano.
In the 13th century the Angevine rules of Naples chose the city a capital of a county, ruled by the di Castro, Del Balzo, Orsini, Campofregoso, Castriota and Sanseverino, Carafa and Gallarati-Scotti families, until feudalism was abrogated in 1806.
