The cities were granted as a fief in 1211–1212 to Otto of La Roche, Duke of Athens, by Geoffrey I of Villehardouin, Prince of Achaea. The lordship remained in the possession of the Brienne Dukes of Athens even after their expulsion from Athens in 1311, and those Dukes continued to be recognized there. Walter VI of Brienne was largely an absentee lord, spending most of his life in his European domains, and the lordship was inherited by his sister Isabella of Brienne at his death in 1356. When she divided her inheritance, her sixth son, Guy of Enghien received the lordship and took up residence there. It passed to his daughter Marie of Enghien when he died in 1376. In 1377, she married Peter Cornaro, who would also reside there until his death in 1388. Shortly after his death, Marie sold the two cities to Venice and retired there.
