History & cultural identity
Kocaeli (historically and culturally known as İzmit), magnificently sprawling around the deep azure gulf waters of the Gulf of İzmit (İzmit Körfezi) and stretching across to the Black Sea coast, holds a monumental ancient Bithynian, Roman, Byzantine, and Ottoman imperial civilizational legacy. 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.
