Dionysius I of Syracuse
Dionysius I of Syracuse repeatedly attempted to take over Enna. At first he encouraged Aeimnestus, a citizen of Enna, to seize the sovereign power. Afterward Dionysius I turned against him and assisted the Ennaeans to get rid of their despot. But it was not till a later period that, after repeated expeditions against the neighbouring Sicilian cities, Dionysius took control of the city by betrayal.
