Nicomēdes in Harpers Dictionary of Classical Antiquities (1898)
Nicomēdes III., surnamed Philopator, king of Bithynia (B.C. 91-74), son and successor of Nicomedes II. Immediately after his accession, he was expelled by Mithridates, who set up against him his brother Socrates; but he was restored by the Romans in the following year (B.C. 90). At the instigation of the Romans, Nicomedes now proceeded to attack the dominions of Mithridates, who expelled him a second time from his kingdom (B.C. 88). This was the immediate occasion of the First Mithridatic War, at the conclusion of which (B.C. 84) Nicomedes was again reinstated in his kingdom. He reigned nearly ten years after this second restoration. He died at the beginning of B.C. 74, and, having no children, by his will bequeathed his kingdom to the Roman people.
Nicomedes III of Bithynia in Wikipedia
Nicomedes III Euergetes (Ancient Greek: Νικομήδης Εὐεργέτης Nikomḗdēs Euergétēs) was the king of Bithynia, from c. 127 BC to c. 94 BC. He was the son and successor of Nicomedes II of Bithynia by an unnamed woman. By his first wife Nysa, he had two sons who were Nicomedes IV of Bithynia, Socrates and a daughter called Nysa, who cause was defended by the Roman Politician Gaius Julius Caesar in gratitude for her father's friendship. 
He made himself for a time master of Paphlagonia, and in order to have a claim on Cappadocia married Laodice of Cappadocia (the widow of Ariarathes VI of Cappadocia), who had fled to him when Mithridates VI of Pontus endeavoured to annex the country. With Laodice's two sons Ariarathes VII and Ariarathes VIII died, Nicomedes brought forward an impostor as a claimant to the throne; but the plot was detected. The Romans refused to recognize the claim, and required Nicomedes to give up all pretensions to Cappadocia and to abandon Paphlagonia. This may be the Nicomedes referred to in 'Fortune's Favourite', & 'Caesar' (Rome series, author Colleen McCullough), see her bibliography for sources.
Quotes When asked to provide troops for Gaius Marius´ war on Cimbri and Teutones in transalpine Gaul in 104 BC he turned down the request declaring: "All those eligible for military service in my kingdom have been robbed by the Roman tax-farmers and sold into slavery"
