Spartocid dynasty in the context of Camasarye Philotecnus

The Bosporan Kingdom, also known as the Kingdom of the Cimmerian Bosporus (Ancient Greek: Βασιλεία τοῦ Κιμμερικοῦ Βοσπόρου, romanized: Basileía tou Kimmerikou Bospórou; Latin: Regnum Bospori), was an ancient Greco-Scythian state located in eastern Crimea and the Taman Peninsula on the shores of the Cimmerian Bosporus, centered in the present-day Strait of Kerch. It was the first truly 'Hellenistic' state, in the sense that a mixed population adopted the Greek language and civilization, under aristocratic consolidated leadership. Under the Spartocid dynasty, the aristocracy of the kingdom adopted a double nature of presenting themselves as archons to Greek subjects and as kings to barbarians, which some historians consider unique in ancient history. The Bosporan Kingdom became the longest surviving Roman client kingdom. The 1st and 2nd centuries AD saw a period of a new golden age of the Bosporan state. It was briefly incorporated as part of the Roman province of Moesia Inferior from AD 63 to 68 under Emperor Nero, before being restored as a Roman client kingdom. At the end of the 2nd century AD, King Sauromates II inflicted a critical defeat on the Scythians and included all the territories of the Crimean Peninsula in the structure of his state.

The prosperity of the Bosporan Kingdom was based on the export of wheat, fish and slaves. As a result, the Kingdom became the economic center of the Black Sea and is often dubbed the ancient Jewel of the Black Sea. The profit of the trade supported a class whose conspicuous wealth is still visible from newly discovered archaeological finds, excavated, often illegally, from numerous burial barrows known as kurgans. The once-thriving cities of the Bosporus left extensive architectural and sculptural remains, while the kurgans continue to yield spectacular Greco-Sarmatian objects, the best examples of which are now preserved in the Hermitage Museum in St. Petersburg. These include gold work, vases imported from Athens, coarse terracottas, textile fragments, and specimens of carpentry and marquetry.

The Bosporan kings were the rulers of the Bosporan Kingdom, an ancient Hellenistic Greco-Scythian state centered on the Kerch Strait (the Cimmerian Bosporus) and ruled from the city of Panticapaeum. Panticapaeum was founded in the 7th or 6th century BC; the earliest known king of the Bosporus is Archaeanax, who seized control of the city c. 480 BC as a usurper. The Archaeanactid dynasty ruled the city until it was displaced by the more long-lived Spartocid dynasty in 438 BC. After ruling for over three centuries, the Spartocids were then displaced by the Mithridatic dynasty of Pontus and then its offshoot the Tiberian-Julian dynasty. The Tiberian-Julian kings ruled as client kings of the Roman Empire until late antiquity.

After several successive periods of rule by groups such as the Sarmatians, Alans, Goths and Huns, the remnants of the Bosporan Kingdom were finally absorbed into the Roman Empire by Justinian I in the 6th century AD following a revolt against the Hunnic ruler Gordas.
