Career
He was Viscount of Aumelas and Lord of Frontignan from 1311 and Prince of Achaea and Morea from 1315. He was sent by Frederick III of Sicily to take command of the Catalan Company in Frederick"s name, but was rebuffed by Bernat de Rocafort, one of their leaders. On his return with the chronicler Ramón Muntaner, he was captured by the Venetians at Negroponte.
He had been released by 1310, when he distinguished himself at the siege of Almería by killing the son of the King of Guadix.
In 1313, he returned to Sicily to take part in the war then in hand with the Angevins and was created Lord of Catania. Margaret of Villehardouin was then in Sicily, seeking to advance her claim to the Principality of Achaea.
He seized Clarenza in June 1315 and briefly took control of the Morea. In the autumn of 1315 he took a second wife, Isabella of Ibelin, daughter of the Seneschal of Cyprus.
Ferdinand"s expected aid from Majorca and Sicily was tardy, as was that of the Catalan Company from Athens.
Facing superior numbers, he was killed at the Battle of Manolada on July 5, 1316.
