Mithridates IV Philopator Philadelphus (in Greek Mιθριδάτης Φιλoπάτωρ Φιλάδελφoς; died c. 150 BC), sixth king of Pontus and son of Mithridates III. The date of his accession to the throne is utterly mysterious, since we first hear of him as ruler only in 154 BC, when he is mentioned as sending an auxiliary force to the assistance of Attalus II against Prusias II, king of Bithynia -- an important event, since it signaled the start of a policy of friendship of Pontus wih Rome and its allies which would continue till Mithridates VI Eupator¹ The only other mention we have of him is as much as twenty-five years before (179 BC): his name is associated with that of his brother Pharnaces in the treaty concluded by the latter with the king of Pergamon Eumenes II, in a manner that would lead one to suppose he was already admitted to some share in the sovereign power.2
