Aegean Sea

The Aegean Sea is a regional sea of the Mediterranean Sea between Greece and Turkey. The Greek mainland forms most of its western coast, while Anatolia forms its eastern coast. Its northern shores include Greek Macedonia and Thrace and the European territory of Turkey. Crete, Karpathos, and Rhodes mark the southern edge of the sea.

The Aegean connects with the Sea of Marmara through the Dardanelles. Together with the Bosporus, this passage forms the maritime route between the Mediterranean and the Black Sea.

Geography

The Aegean Sea contains a large number of islands, channels, bays, and peninsulas. Its main island groups include the Cyclades, Dodecanese, Sporades, Saronic Islands, and the North Aegean Islands. Euboea lies close to the eastern coast of mainland Greece, while Crete forms the largest island along the southern boundary.

The western coast contains the Greek regions of Macedonia, Thessaly, Central Greece, Attica, and the eastern Peloponnese. The Turkish coast includes the Gallipoli Peninsula and the western shoreline of Anatolia. Major coastal inlets include the Thermaic Gulf, Pagasetic Gulf, Euboean Gulf, Saronic Gulf, Gulf of Edremit, Gulf of İzmir, and Gulf of Kuşadası.

Several rivers flow into the northern Aegean. The Vardar River, known as the Axios in Greece, crosses North Macedonia and northern Greece before reaching the sea west of Thessaloniki. The Maritsa, Struma, and Mesta rivers also drain parts of the eastern and central Balkans into the northern Aegean.

The sea contains deep basins, narrow island channels, rocky coasts, beaches, wetlands, and seagrass habitats. Marine life includes fish, dolphins, seals, seabirds, shellfish, and other Mediterranean species. Fishing, shipping, coastal construction, tourism, pollution, and rising water temperatures affect its coastal and marine environments.

History and maritime use

The Aegean coast and islands supported some of the earliest urban and maritime societies in Europe. The Minoan civilization developed on Crete, while the Mycenaean civilization occupied parts of mainland Greece and several islands. Maritime routes connected settlements, ports, and trading centres throughout the basin.

Ancient Greek communities developed around the sea and established cities on both the European and Anatolian coasts. Athens, Miletus, Ephesus, Rhodes, and other centres used Aegean routes for trade, colonisation, military movement, and communication. The region later came under Macedonian and Roman authority.

The Aegean remained an important maritime region under the Byzantine Empire. During the medieval and early modern periods, its ports and islands were contested or governed by Byzantine, Venetian, Genoese, and Ottoman authorities. The Ottoman Empire gradually gained control of most of the surrounding coasts and islands.

The modern political geography of the sea developed through Greek independence, the decline of Ottoman authority in southeastern Europe, and territorial changes during the nineteenth and twentieth centuries. Most Aegean islands became part of Greece, while the eastern mainland coast remained part of Turkey.

The sea supports commercial shipping, passenger ferries, fishing, tourism, and naval movement. Major ports on or connected to the Aegean include Piraeus, Thessaloniki, Volos, Alexandroupoli, İzmir, and Çanakkale. Ferry routes connect the Greek mainland with the islands and provide services between neighbouring island groups.

Ships travelling between the Black Sea and the wider Mediterranean pass through the Bosporus, the Sea of Marmara, the Dardanelles, and the northeastern Aegean. The sea also connects the southern Balkans and western Anatolia with routes toward the eastern Mediterranean and the Suez Canal.
