History
The Marmara has been a crossroads since the Bronze Age. Troy, on the mound of Hisarlık above the Dardanelles, was rebuilt again and again over some four thousand years, and its later layers are linked with the city of Homer's Iliad. Greek colonists founded Byzantium on the Bosphorus in the 7th century BC, and in 330 AD Constantine refounded it as Constantinople, capital of the Eastern Roman Empire. Nicaea, today's İznik, hosted the first ecumenical council of the Church in 325.
The Ottoman state grew up on the region's southern edge. Osman's son Orhan took Bursa in 1326 and made it the first great Ottoman capital; the dynasty then crossed into Europe and moved its seat to Edirne, the Roman Adrianople, in the 14th century. Mehmed II set out from Edirne to take Constantinople in 1453, and for the next four and a half centuries Istanbul was the imperial capital, a city of Turks, Greeks, Armenians and Jews.
The empire's end was fought out here too. In 1915 Allied fleets and armies tried to force the Dardanelles, and the Gallipoli campaign cost more than 100,000 lives before the Allies withdrew in January 1916; a young officer, Mustafa Kemal, made his name there. Allied forces occupied Istanbul after 1918, and the republic moved the capital to Ankara in 1923. The population exchange with Greece reshaped Thrace and the coast, and the Balkan migrants who arrived through the century still give the region much of its character. The İzmit earthquake of 1999 killed more than 17,000 people, a reminder of the fault beneath the sea.
