The Congress of Gela was a diplomatic meeting between a number of Sicilian cities in 424 BC. It brought a temporary halt to several years of warfare between cities on the island. At the conference, the Sicilian cities agreed to a Syracusan proposal to make peace and agree to a platform of "Sicily for the Sicilians", which has been compared to the Monroe Doctrine. Though the agreement was intended to be perpetual, both war and outside involvement in Sicilian affairs resumed within a few decades.
