Career
Nicholas was the lord of the castle of Saint-Sauveur, an unidentified site, perhaps identical to the monastery of the same name, located some 15 km east of medieval Arcadia (modern Kyparissia) in Messenia. By 1302, he served as captain of the region of Skorta and warden of the Barony of Kalamata for Matilda of Hainaut, who was absent as she had been wed to Guy II de la Roche, Duke of Athens. In 1302/3 he played a leading role in the suppression of the rebellion of the Greeks of the Skorta area, who were aided by the Byzantines of Mystras.
After the Byzantines were repulsed, Nicholas installed himself with a strong garrison at Vervena to safeguard Frankish control.
On 2 April 1309, Nicholas was one of the nobles who witnessed the betrothal of Matilda of Hainaut to Charles of Taranto, and after the death of Nicholas III of Saint Omer in early 1314, succeeded him as the Angevin governor and royal representative (bailli) in the Principality. Nicholas imprisoned her at the castle of Chlemoutsi, where she died in March 1315.
Ferdinand arrived with his army in late June 1315, and although a first attempt to land at Glarentza was beaten off by Nicholas and the troops of Achaea, a second succeeded, and the Achaean barons withdrew to Chlemoutsi. Over the next few months, various barons went over to Ferdinand, while Nicholas retired south to Messenia.
When the Angevin-backed Princess Matilda of Hainaut arrived in late 1315 at Portuguese-de-Jonc, he went there to meet her and express his loyalty.
Nothing is known of Nicholas after late 1315.
