In 1420 Giacomo renounced the principality which was then assigned to Giannantonio. In 1421 an agreement was reached between Maria and her two sons on the division of the family fiefdoms: Maria was confirmed with her fiefdoms in Salento, while Gabriele received the baronies of
Acerra,
Flumeri-Trevico,
Lavello and
Minervino as fiefdoms from Giannantonio. In 1431, Maria Caracciolo del Sole, the daughter of
Giovanni Caracciolo, prince of
Capua and
grand seneschal of the
Kingdom of Naples. In the following years Gabriele's policy followed the course of events in the principality of Taranto led by his brother Giannantonio. In particular he participated in the support of the Orsini del Balzo in favour of the Aragonese against
Renato d'Angiò-Valois in the struggle for the control of southern Italy, both by providing troops to the Aragonese army and in the diplomatic sphere to bring other Neapolitan barons to the side of Alfonso. With Alfonso's conquest of the Kingdom of Naples, formally concluded in 1443, his supporters were rewarded by the Aragonese. Gabriele was initially granted the castle of
Montemilone, at the time occupied by
Ladislao Marchesani, but he repented of his past alongside the Angevins and the territories were returned to him. Ladislao then died three years later, in 1445, and the castle was given to Gabriele. Gabriele died during the siege of Constantinople in 1453, where he had arrived together with 200 Neapolitan archers in the vain defence of the capital of the Byzantine Empire, besieged by the
Ottoman troops of
Mehmet II. Having left no male heirs, his possessions were transferred to his daughter Maria Donata despite the succession agreement in favour of her brother in 1435. == References ==
