After the departure of the allies the new city and the fate of Messenian independence were left in the hands of the Messenian exiles, who had returned primarily from Sicily and North Africa. Apparently they had maintained a transitory community in exile, or diaspora, for some 300 years. They spoke a Doric dialect. Pausanias reports, "even to this day they preserve it in its purity better than anywhere else in the Peloponnese." As the Arcadians are known to have spoken a dialect closely related to Mycenaean Greek, the exiles restored were not from the original Achaean refugees of the return of the Heracleidae, but were the Doricised population that developed in the 7th century BC under the subsequently dispossessed Heraclid dynasty of Messene.
