The Bosporan Kingdom, also known as the Kingdom of the Cimmerian Bosporus (Greek: Βασίλειον του Κιμμερικού Βοσπόρου Basileion tou Kimmerikou Bosporou), was an ancient state located in eastern Crimea and the Taman Peninsula on the shores of the Cimmerian Bosporus, the present-day Strait of Kerch. (It was not named after the more famous Bosphorus beside Istanbul at the other end of the Black Sea.) The Bosporan Kingdom was the longest surviving Roman client kingdom. It was a Roman province from 63 to 68 AD, under Emperor Nero. The 1st and 2nd centuries BC saw a period of renewed golden age of the Bosporan state.
