Dionysius I of Syracuse
In 406 BC, the Carthaginians conquered Agrigento and destroyed it. Gela asked for the help of Dionysius I of Syracuse but for unknown reasons, Dionysius did not arrive in time and, after heroic deeds, the following year, Gela was ruined in and its treasures were sacked. The survivors took refuge in Syracuse. In 397 BC, they returned in Gela and joined Dionysius II in his struggle for freedom from the invaders, and in 383 BC, their independence was acknowledged.
