No later mention of Morgantina is made until Thucydides lists it as part of the terms of a truce in the war of 427–424 BCE between Syracuse and the Dorian cities of Sicily on one side, and Kamarina, the Khalkidian cities of Sicily, the Sikels, and Athens on the other side. Thucydides says that Syracuse agreed at the Congress of Gela to give Morgantina to Kamarina in return for payment of an indemnity. Kamarina was destroyed in 405 by the Carthaginians. Morgantina therefore must have been independent from at least this date, although it was soon recaptured by Dionysios of Syracuse in 396. Syracuse retained (occasionally more nominal than actual) control of Morgantina until the Second Punic War. In 317, Morgantina received the tyrant Agathocles, then in exile, and offered him help in returning to Syracuse. He was elected "praetor" at Morgantina, and later "dux".
