On the southern coast, among the Greek towns devoted to commerce, Tarentum passed for the most powerful; but these colonies, already in decline, were obliged to have recourse to mercenary troops, to resist the native inhabitants. They disputed with the Samnites and the Romans the preponderance over the people of Magna Græcia. The Samnites, indeed, a manly and independent race, aimed at seizing the whole of Southern Italy; their cities formed a confederacy, redoubtable on account of its close union in time of war. The mountain tribes gave themselves up to brigandage, and it is worthy of attention that recent events show that in our days manners have not much changed in that country. The Samnites had amassed considerable riches; their arms displayed excessive extravagance, and, if we believe Cæsar,[163] they served as models for those of the Romans.

A jealous rivalry had long prevailed between the Romans and the Samnites. The moment these two peoples found themselves in presence of each other, it was evident that they would be at war; the struggle was long and terrible, and, during the fifth century, it was round Samnium that they disputed the empire of Italy. The position of the Samnites was very advantageous. Entrenched in their mountains, they could, at their will, either descend into the valley of the Liris, thence reach the country of the Aurunci, always ready to revolt, and cut off the communications of Rome with Campania; or follow the course of the upper Liris into the country of the Marsi, raise these latter, and hold out the hand to the Etruscans, turning Rome; or, lastly, penetrate into Campania by the valley of the Vulturnus, and fall upon the Sidicini, whose territory they coveted.

In the midst of so many hostile peoples, for a little state to succeed in raising itself above the others, and in subjugating them, it must have possessed peculiar elements of superiority. The peoples who surrounded Rome, warlike and proud of their independence, had neither the same unity, nor the same incentives to action, nor the same powerful aristocratic organisation, nor the same blind confidence in their destinies. They displayed more selfishness than ambition. When they fought, it was much more to increase their riches by pillage than to augment the number of their subjects. Rome triumphed, because alone, in prospect of a future, she made war not to destroy, but to conserve, and, after the material conquest, always set herself to accomplish the moral conquest of the vanquished.
