(Μολπαγόρας), a demagogue of Cios, in Bithynia, who, by the usual arts of his class, raised himself to absolute power in his state. To the imprudence of the men of Cios, in placing confidence in him and in persons like him, Polybius ascribes mainly the capture of their city by Philip V. of Macedon, in B. C. 202. (Plb. 15.21; comp. Liv. 32.33, 34.)
