History & cultural identity
Known in antiquity as Nicomedia, an eastern co-capital of the Roman Empire under Diocletian, Kocaeli has long commanded the narrow maritime gateway into Marmara. Founded anciently in the 8th century BC as Astakos and later refounded in 264 BC by King Nicomedes I as Nicomedia (Nikomedia), the city attained its greatest historical glory as the grand eastern capital of the Roman Empire under Emperor Diocletian. Following successive rule by Byzantium and the Ottomans (conquered by Akçakoca in 1337), the region evolved into a vital maritime and commercial hub. In the modern era, Kocaeli transformed into Türkiye's absolute industrial manufacturing, technological, and automotive powerhouse, combining ancient imperial ruins with cutting-edge techno-parks and massive port logistics.
