Nicomēdes I., a king of Bithynia, about 278 years before the christian era. It was by his exertions that this part of Asia became a monarchy. He behaved with great cruelty to his brothers, and built a town which he called by his own name, Nicomedia. Justin.Pausanias, &c.

Nicomēdes II., was ironically surnamed Philopater, because he drove his father Prusias from the kingdom of Bithynia, and caused him to be assassinated, B.C. 149. He reigned 59 years. Mithridates laid claim to his kingdom, but all their disputes were decided by the Romans, who deprived Nicomedes of the province of Paphlagonia, and his ambitious rival of Cappadocia. He gained the affections of his subjects by a courteous behaviour, and by a mild and peaceful government. Justin.

Nicomēdes III., son and successor of the preceding, was dethroned by his brother Socrates, and afterwards by the ambitious Mithridates. The Romans re-established him on his throne, and encouraged him to make reprisals upon the king of Pontus. He followed their advice, and he was, at last, expelled another time from his dominions, till Sylla came into Asia, who restored him to his former power and affluence. Strabo.Appian.

Nicomēdes IV., was son and successor of Nicomedes III. He passed his life in an easy and tranquil manner, and enjoyed the peace which his alliance with the Romans had procured him. He died B.C. 75, without issue, and left his kingdom, with all his possessions, to the Roman people. Strabo, bk. 12.—Appian, Mithridatic Wars.—Justin, bk. 38, ch. 2, &c.Florus, bk. 3, ch. 5.
