Carlo I Tocco
However, Centurione was quickly at war with his alienated relatives. His wife's cousin Carlo I Tocco, duke of Leucas, had Ladislaus absolve him from his feudal obligations to Achaea (1406) and then, allied with Theodore I Palaiologos, Despot of Morea, made war on the principality, conquering Glarentza (1408), long the principality's chief seaport. His brother Stephen, however, abandoned the diocese of Patras to the Venetians on loan for five years. Centurione himself was forced to ally with the Venetians and Justinian, Lord of Chios, and to hire Albanian mercenaries to retake the port on 12 July 1414. In return for military protection, he granted the ports of Glarentza and Navarino to the Giustiniani family of Genoa.
