Fürstentum Tarent
His second son, Raimondello Orsini del Balzo, supported Charles III' "coup d'état" in Naples against Queen Joan I. Under king Ladislaus he was among the few Neapolitan feudataries who were able to maintain their territorial power after the royal war against them. However, at his death in 1406 the southern Orsini fiefs were confiscated. Relationships with the royal family remained cold under Joan II; However, when Raimondello's son Giannantonio (1386–1453) sent his troops to help her against the usurpation attempt of James of Bourbon, he received in exchange the Principality of Taranto.
