A contest greater than with Pyrrhus and the Greek cities, more memorable in its incidents, and more important in its consequences, now awaited the Romans. This was with Carthage, the greatest power, next to Rome, in the world at that time—a commercial State which had been gradually aggrandized for three hundred years. It was a rich and powerful city at the close of the Persian wars. It had succeeded Tyre as the mistress of the sea.
Causes of the Punic war.
We have seen, in the second book, how the Carthaginians were involved in wars with Syracuse, when that city had reached the acme of its power under Dionysius. We have also alluded to the early history and power of Carthage. At the time Pyrrhus landed in Sicily, it contained nearly a million of people, and controlled the northern coast of Africa, and the western part of the Mediterranean. Carthage was strictly a naval power, although her colonies were numerous, and her dependencies large. The land forces were not proportionate to the naval; but large armies were necessary to protect her dependencies in the constant wars in which she was engaged. These armies were chiefly mercenaries, and their main strength consisted in light cavalry.
Territories of Carthage. Sicilian affairs.
The territories of Carthage lay chiefly in the islands which were protected by her navy and enriched by her commerce. Among these insular possessions, Sardinia was the largest and most important, and was the commercial depot of Southern Europe. A part of Sicily, also, as we have seen ([Book ii., chap. 24]), was colonized and held by [pg 430] her, and she aimed at the sovereignty of the whole island. Hence the various wars with Syracuse. The Carthaginians and Greeks were the rivals for the sovereignty of this fruitful island, the centre of the oil and wine trade, the store-house for all sorts of cereals. Had Carthage possessed the whole of Sicily, her fleets would have controlled the Mediterranean.
Rhegium.
The embroilment of Carthage with the Grecian States on this island was the occasion of the first rupture with Rome. Messina, the seat of the pirate republic of the Mamertines, was in close alliance with Rhegium, a city which had grown into importance during the war with Pyrrhus. Rhegium, situated on the Italian side of the strait, solicited the protection of Rome, and a body of Campanian troops was sent to its assistance. These troops expelled or massacred the citizens for whose protection they had been sent, and established a tumultuary government. On the fall of Tarentum, the Romans sought to punish this outrage, and also to embrace the opportunity to possess a town which would facilitate a passage to Sicily, for Sicily as truly belonged to Italy as the Peloponnesus to Greece, being separated only by a narrow strait. A Roman army was accordingly sent to take possession of Rhegium, but the defenders made a desperate resistance. It was finally taken by storm, and the original citizens obtained repossession, as dependents and allies of Rome. The fall of Rhegium robbed the pirate city of Messina of the only ally on which it could count, and subjected it to the vengeance of both the Carthaginians and the Syracusans. The latter were then under the sway of Hiero, who, for fifty years, had reigned without despotism, and had quietly developed both the resources and the freedom of the city. He collected an army of citizens, devoted to him, who expelled the Mamertines from many of their towns, and gained a decisive victory over them, not far from Messina.
The Mamertines.
The Mamertines, in danger of subjection by the Syracusans, then looked for foreign aid. One party looked to Carthage, [pg 431] and another to Rome. The Carthaginian party prevailed on the Mamertines to receive a Punic garrison. The Romans, seeking a pretext for a war with Carthage, sent an army ostensibly to protect Messina against Hiero. But the strait which afforded a passage to Sicily was barred by a Carthaginian fleet. The Romans, unaccustomed to the sea, were defeated. Not discouraged, however, they finally succeeded in landing at Messina, and although Carthage and Rome were at peace, seized Hanno, the Carthaginian general, who had the weakness to command the evacuation of the citadel as a ransom for his person.
