Nicholas III of Saint-Omer

It was on his advice that Guy II de la Roche, the young Duke of Athens, was wed to the daughter and heiress of Princess Isabella of Villehardouin, Matilda of Hainaut, in an effort to improve the relations of the two most powerful, and often rival, Frankish states of Greece, and establish an alliance between them.

The Epirotes were pushed back, and the Frankish army raided as far as the Byzantine province around Thessalonica, from where they withdrew at the request of the Empress Yolande of Montferrat.

[1][6] Charles was determined to renew his attack the next spring, but Anna of Epirus managed to sabotage his plans by bribing Philip of Savoy to stay at home.

[3] In this role, in 1304 he opposed Philip of Savoy and helped Margaret secure part of the inheritance of her husband, the count of Cephalonia Richard Orsini, from her stepson, John I.

[8] According to the Aragonese version of the Chronicle of the Morea, he also served once more as bailli after Gilles de la Plainche (attested in office in 1311), possibly until his death, when he was succeeded by Nicholas le Maure.
