In the second great city on the east coast, Messana, a band of foreign soldiers had established themselves and held the city, independent alike of Syracusans and Carthaginians. These new rulers of Messana were Campanian mercenaries. The dissolute habits that had become prevalent among the Sabellians settled in and around Capua,(1) had made Campania in the fourth and fifth centuries--what Aetolia, Crete, and Laconia were afterwards--the universal recruiting field for princes and cities in search of mercenaries. The semi-culture that had been called into existence there by the Campanian Greeks, the barbaric luxury of life in Capua and the other Campanian cities, the political impotence to which the hegemony of Rome condemned them, while yet its rule was not so stern as wholly to withdraw from them the right of self-disposal--all tended to drive the youth of Campania in troops to the standards of the recruiting officers. As a matter of course, this wanton and unscrupulous selling of themselves here, as everywhere, brought in its train estrangement from their native land, habits of violence and military disorder, and indifference to the breach of their allegiance. These Campanians could see no reason why a band of mercenaries should not seize on their own behalf any city entrusted to their guardianship, provided only they were in a position to hold it--the Samnites had established their dominion in Capua itself, and the Lucanians in a succession of Greek cities, after a fashion not much more honourable. Mammertines Nowhere was the state of political relations more inviting for such enterprises than in Sicily. Already the Campanian captains who came to Sicily during the Peloponnesian war had insinuated themselves in this way into Entella and Aetna. Somewhere about the year 470 a Campanian band, which had previously served under Agathocles and after his death (465) took up the trade of freebooters on their own account, established themselves in Messana, the second city of Greek Sicily, and the chief seat of the anti-Syracusan party in that portion of the island which was still in the power of the Greeks. The citizens were slain or expelled, their wives and children and houses were distributed among the soldiers, and the new masters of the city, the Mamertines or "men of Mars," as they called themselves, soon became the third power in the island, the north-eastern portion of which they reduced to subjection in the times of confusion that succeeded the death of Agathocles. The Carthaginians were no unwilling spectators of these events, which established in the immediate vicinity of the Syracusans a new and powerful adversary instead of a cognate and ordinarily allied or dependent city. With Carthaginian aid the Mamertines maintained themselves against Pyrrhus, and the untimely departure of the king restored to them all their power.
