The Mithridatic dynasty ruled the kingdom of Bosporus, with its last member being Dynamis.
He married Gepaepyris, daughter of Cotys III (Sapaean) king of Thrace and some of his descendants had thracian royal names like Cotys, Rhescouporis and Roemetalces.
The dynasty had strong family relations to Roman Emperors, and the kingdom lasted longer than any other Hellenistic one.
The last king died on 342 AD, when Constantius II was Emperor.
Then the Huns captured the kingdom, after that Utigurs and later Goths.
