But I must return to the story of the advance of Rome in Italy. It seems clear that after the Gallic invasion the Latins became more and more discontented with Roman policy, which probably aimed at utilising all the resources of the league and at the same time getting complete control of its relations to other powers. We have the text in Greek, preserved by the historian Polybius, of a treaty with Carthage, then the greatest naval power in the Mediterranean, which well illustrates this: the date is 348 B.C. Rome acts for Latium in negotiating this treaty; and Carthage undertook not to molest the Latin cities, provided that they remained faithful to Rome; nay, even to restore to the power of the leading city any revolting Latin community that might fall into their hands. This plainly shows that revolt was expected, and a few years later it became general. But in spite of the support of the Campanians in the rich volcanic plain farther south, and indeed of danger so great that it gave rise to another story of the “devotio” of a Roman consul to the infernal deities on behalf of the State, the Latins were completely beaten at the battle of Mount Vesuvius, and the Romans were able so to alter the league as to deprive it of all real claim to be called a federation.

We saw that any citizen of a Latin city could buy and hold property, marry and have legitimate children, in any other Latin city, knowing that he was protected by the law in the enjoyment of these rights. But after the rebellion this was all changed. A citizen could enjoy these rights in his own city, or at Rome, but nowhere else, while a Roman could enjoy them everywhere. A citizen of Præneste, for example, could enjoy them at Præneste or Rome, but not in the neighbouring cities of Tibur or Tusculum: while a Roman could do business in all these cities, and be supported in all his dealings by the Roman law, which now began gradually to permeate the whole of Latium. Rome thus had a monopoly of business with the other cities, which were effectually isolated from each other. To us this seems a cruel and selfish policy, and so in itself it was. But we must remember that Rome had been all but destroyed off the face of the earth, and that the Latins had done nothing, so far as we know, to help her. To resist another such attack as that of the Gauls, it was absolutely necessary for Rome to control the whole military resources of Latium, and this she could not do in a loose and equal federation. She was liable not only to assaults from the Gauls, but from Etruscans, and, as we shall see directly, from Samnites, and, if we find that in the struggle for existence she was at times unjust, we may remember that there has hardly been a successful nation of which the same might not be said. She saw that Latium must become Roman if either Rome or the Latins were to survive, and she devised the principle of isolation with this object.

From this time all Latins served in Roman armies nominally as allies, but in reality as subjects; and all Latins who became Roman citizens served in the Roman legions. When a military colony was founded, it might be either Roman or Latin; but a Latin colony meant not necessarily a collection of Latins; it might admit any one—Roman, Latin or other, who threw in his lot with the new city and accepted the two rights of trade and marriage described above. Thus the term Latin came to mean not so much a man of a certain stock as a man with a certain legal position, and so it continued for many centuries, while the new power rising to prominence in the world came to be known not as Latin, but as Roman.

The last and decisive battle with the Latins took its name, as we saw, from Mount Vesuvius, and the reader who knows the map of Italy will ask how it came to be fought so far south of Latium, in the large and fertile plain of Campania, near the modern city of Naples. The answer is that a powerful State, such as Rome was now becoming, is liable to be appealed to by weaker communities when in trouble; and the Campanians, attacked by the hill-men from the central mountainous region of the Samnites, had appealed for help to Rome. This was given, but the Romans found it necessary to make peace with these Samnites, and left the Campanians in the lurch, and then the latter threw in their lot with the Latins, and the Latin war drifted south to Campania. At the end of that war they were treated in much the same way as the Latins; and thus Rome now found herself presiding with irresistible force over a territory that included both the plains of western Italy and all its most valuable land, and over a confederacy in which all the advantages were on her side, and all the resources of the members under her control.

But to be mistress of these two plains was not as yet to be mistress of Italy. Those plains, and especially the southern and more valuable one, had to be defended from the mountaineers of the central highlands of the peninsula: a region which the reader should at this point of our story study carefully in his map. Towards the end of the Latin war these highlanders, Samnites, as the Romans called them, had ceased raiding the Campanian plain, for they in their turn had to defend southern Italy against an unexpected enemy. The strong and wealthy Greek merchant-city of Tarentum, just inside the “heel” of Italy, destined to play an important part in Italian history for the next century, had lately had its lands raided by the Samnites and their kin the Lucanians to the south of them, and had called in Greeks from oversea to help them. Here we come into touch with Greek history, just at the time when Alexander the Great was the leading figure in the Greek world. A Spartan king came over to aid Tarentum, and lost his life in so doing; then Alexander of Epirus was induced to come, an uncle of the great conqueror: and after a period of success against the Samnites, he was assassinated. It is said that Rome came to an understanding with him, and it is likely enough; there must have been men in the great Council at Rome who were already accustomed to look far ahead, and keep themselves informed of what was going on far away in Italy and even beyond the Italian seas. Her long struggle for existence had taught her venerable statesmen the arts of diplomacy, and we are not surprised to learn that after the death of Alexander she began to form alliances in that far country between the Samnites and Tarentum, much of which was rich and fertile, in order that when the inevitable struggle with the hill-men should come, she might have them enclosed between two foes—herself and Latium on the north and west, and the Apulians and Greeks in the south and east. It seemed as if her power and prestige must continually go forward, or collapse altogether; the same alternative that faced the English in India in the eighteenth century and later. In neither case did the advancing power fully realise what the future was to be.

The inevitable struggle with the Samnites came, and lasted many years. We need not pursue it in detail, and indeed the details are quite untrustworthy as they have come down to us; but one episode in it is told so explicitly and has become so famous, that it deserves a place in our sketch as showing that hard feeling of national self-interest, without a touch of chivalry, that is gradually emerging as the guide of Roman action in her progress towards universal dominion.

A strong Roman army, under the command of both consuls, was pushing to the south through the mountains, and fell into a trap in a defile called the Caudine Forks,[3] a name never forgotten by the Romans. All attempts to escape were vain, and they were forced to capitulate. The terms dictated by Pontius the Samnite general were these: the consuls were to bind themselves on behalf of the Senate to agree to evacuate Samnium and Campania and the fortresses (coloniæ) which had been planted there, and to make peace with the Samnites as with an equal power. The consuls bound themselves by a solemn rite, and the army was allowed to go home, after being sent under the yoke, i.e. under a kind of archway consisting of one spear resting on two upright ones: this was an old Italian custom of dealing with a conquered army, which may have originally had a religious signification. When the disgraced legions reached Rome, and the consuls summoned the Senate to ratify their bond with Pontius, the Fathers, as they were called, positively refused to do so. The consuls and all who had made themselves responsible for the terms were sent back to Pontius as his prisoners, but not the army. His indignation was great, for he knew that Samnium had lost her chance, and would never have it again. The consuls, of course, had no power to bind the Senate, and the Samnite terms were such as the Senate could not accept as the result of a single disaster caused by a general’s blunder: that was not the way in which the Romans carried on war. But the disgraced army should have been sent back too, and the Senate and people knew it. The speech which the later Roman historian puts into the mouth of Pontius to express his indignation, shows that some feeling of shame at this dishonourable action had come down in the minds of many generations.

The last effort of this long struggle against Rome was a desperate attempt to combine the forces of Samnites, Etruscans and Gauls: the idea was to separate her armies and thus crush her in detail. Even this was a failure, and without going into the doubtful stories of the fighting, we may ask why it was so. Beyond all doubt the Roman power was for a time in very great peril; but in the end it prevailed, and this is a good moment for pausing to think about the advantages that Rome’s genius for organisation had secured for herself; advantages which no other Italian stock seemed able to acquire.

First, she had learnt how to use with profit her geographical position; to north, south and east she could send armies to strike in different directions at the same time; and she must have devised some means (though we do not know the method) of keeping up communication between these armies. The stories seem to suggest that the commanders of this period belonged to a very few noble families whose members had spent their whole lives in fighting—not indeed merely in fighting battles, but in carrying on war: the Fabii and Papirii are particularly prominent. These veterans must have come to know the art of war thoroughly, as it could then be applied in Italy, and also the details of the country in which they had to fight.

Secondly, the efforts of these tough old heroes were admirably seconded by the home government, i.e. the Senate, because this assembly consisted of men of the like military experience, and the leaders among them were themselves generals, men who had been consuls and had led armies. Though at this very time, as we shall see, there was a strong tendency towards popular government, yet in the direction of war we find no sign that the monopoly of the old families was questioned; and as their interests and their experience were all of the same type, they could act together with a unanimity which was probably unknown to their enemies. The fact that Rome always at this time, and indeed at all times, negotiated and kept in touch with the aristocracies in the Italian cities, shows how completely the noble families had gained control over the management of diplomacy as well as war.
