 Pope Callixtus III (in office 1455-1458) hoped to establish a new military order on the island, which controlled the exit of the Dardanelles, but nothing came of it as Isma'il Bey soon recovered Lemnos for the Sultan.In 1464, during the First Ottoman–Venetian War,the Venetians seized Lemnos and other former Gattilusi possessions, but the area reverted to Ottoman control in accordance with the 1479 Treaty of Constantinople.In the aftermath, the Kapudan Pasha, Gedik Ahmed, repaired the island's fortifications and brought in settlers from Anatolia.
