In 1313, he took part in a complex marriage pact designed to secure control by the Angevins and the Burgundians over Frankish Greece.

On 31 July 1313 he married Matilda of Hainaut, heir-general of William II Villehardouin, to whom Philip I of Taranto gave the Principality of Achaea in fief.

Ferdinand of Majorca, who also claimed the principality jure uxoris (his wife Isabelle de Sabran was descended from the younger daughter of William II Villehardouin), had landed there in 1315 and taken to Glarentza.

Ferdinand sent for aid from the Kingdom of Majorca and the Catalan Company, but neither arrived in time to prevent his death and defeat by Louis at the Battle of Manolada on 5 July 1316.

The Chronicle of the Morea attributes his death to a fever, while the Catalan Declaratio summaria states that he was poisoned by Count John of Cephalonia.
