Carlo I Tocco
Around 900 A.D, the Byzantine fleet from Naupaktos (Lepanto) at the Gulf of Corinth became and capital and became Nikopolis. The new capital became secured by the fortress. One of these fortresses were favourable for defense on the island and the lagoons in Aitoliko. Since the 12th century, the island fortress of Anatoliko developed to the city. In 1406, it was sold to Carlo I Tocco of Kefallinia. The Venetian forces divided their incomes from the salt gardens and fishing waters of Anatoliko which lasted until 1430.
