Nerio's troops captured Neopatras before the end of 1390. King Ladislaus of Naples appointed Nerio as his vicar-general in Achaea and in Lepanto in 1391, but Ladislaus had no authority in the principality. Amadeus of Savoy sent envoys to Athens to secure Nerio's support for himself. On 29 December 1391, Nerio recognized Amadeus as his suzerain in return for a promise of the restoration of his Achaean estates, but Amadeus could never assert his authority in the principality. Nerio dispatched Lodovico Aliotti, Archbishop of Athens, to Ladislaus of Naples to achieve the legitimization of his rule in Athens. Ladislaus accepted the offer and granted the Duchy of Athens to Nerio and his legitimate male heirs on 11 January 1394.
