Thracian Sea
The Thracian Sea occupies the northernmost Aegean, receiving the Strymon, Nestos and Evros rivers and opening toward the Dardanelles. Thasos, Samothrace and Imbros lie in its waters. After the fall of Constantinople, the Imbrian leader Michael Critoboulos helped arrange his island's peaceful submission to the Ottomans. Its position near the straits remained significant: in 1717 Venetian and Ottoman fleets fought an inconclusive battle off Imbros.
