Demarchus
Δήμαρχος
(Δήμαρχος), son of Pidocus, a Syracusan. He was one of the generals sent out to replace Hermocrates and his colleagues in the command of the Syracusan auxiliaries in Greece, when those generals were banished. (Thuc. 8.85; Xen. Hell. 1.1.30.) After his return he appears to have taken a leading part in public affairs, and became one of the most powerful opponents of the rising power of Dionysius. He was in consequence put to death at the instigation of the latter, at the same time with Daphnaeus, shortly after Dionysius had been appointed general autocrator. (Diod. 13.96.)
