In the 5th–4th centuries BC, the city became the residence first of the
Archaeanactids and then of the
Spartocids, dynasties of
Thracian kings of
Bosporus, and was hence itself sometimes called Bosporus. Its economic decline in the 4th–3rd centuries BC was the result of the
Sarmatian conquest of the steppes and the growing competition of
Egyptian grain.
Mithridates with bows from Panticapeum, 4th century BC The last of the
Spartocids,
Paerisades V, apparently left his realm to
Mithridates VI Eupator, king of
Pontus. This transition was arranged by one of Mithridates's generals,
Diophantus, who earlier had been sent to Taurica to help local Greek cities against
Palacus of the
Scythian kingdom in Crimea. The mission did not go smoothly: Paerisades was murdered by
Scythians led by
Saumacus, and Diophantus escaped to return later with reinforcements to suppress the revolt (c. 110 BC). Half of a century later, Mithridates took his life in Pantikapaion, when, after his defeat in a
war against
Rome, his son and heir
Pharnaces and citizens of Pantikapaion turned against him. == First centuries AD ==
