Amadeus, Prince of Achaea
Nerio I Acciaioli, Duke of Athens, had been a one-time employer of the Navarrese Company, but having been imprisoned at Listrina for a year from September 1389 by the Navarrese master Pedro de San Superano, he abandoned his erstwhile allies and began talks with Amadeo, who had written letters of condolence to Nerio's relatives.On 29 December 1391, Amadeo's representatives met with Nerio in the palace chapel on the Acropolis and signed a pact against the Navarrese then controlling the Morea.Nerio agreed to recognise Amadeo as Prince of Achaea and his legal suzerain for the lordship of Corinth and the duchy of Athens and Neopatria.Meanwhile, Amadeo had also been negotiating with Pedro and he had secured Navarrese recognition of his title in return for the confirmation of their vast holdings.Venice had also made an accord with Amadeo and were ready to transport himself and his army by sea to Greece in return for his aid in reconquering Argos from the Despotate of Morea.
