In 1404, Ladislaus, King of Naples, installed Centurione II Zaccaria, the lord of Arkadia (modern Kyparissia), as prince. Centurione continued to hold the post until 1430, when invasions by the Despots of the Morea, Constantine Palaiologos and Thomas Palaiologos, conquered the heartland of the Principality in Achaea. Centurione married off his daughter and heiress, Catherine, to Thomas, and retreated to his ancestral Messenian castle. On his death in 1432, this too was seized by the Byzantines. In about 1450, his illegitimate son, John Asen, was the focus of rebellions against Constantine, who was despot at the time. The Byzantine reconquest proved short-lived, however, as in 1460, the Ottomans conquered the Despotate.
