Mithridates IV Philopator Philadelphus

Mithridates IV succeeded his brother Pharnaces I, who had conquered Sinope and lost Paphlagonia. Little is known about the reign of Mithridates, except for the fact that he was allied to the Romans and supported Attalus II Philadelphus of Pergamon against Prusias II the Hunter of Bithynia. He was succeeded by his nephew Mithridates V, a son of Pharnaces.
