James of Piedmont

James was the Lord of Piedmont from 1334 to his death. He was the eldest son of Philip I and Catherine de la Tour du Pin. While his father had been stripped of the Principality of Achaea in 1307 by the Angevins of the Kingdom of Naples, James continued to use the princely title and even passed it on to his successors. However, James was not a son of Isabella Villehardouin - the first wife of his father - and thus not a descendant of the Villehardouin dynasty.
