The Samnite land, properly so called, alone remained unaffected by these innovations, which, beautiful and natural as they may to some extent have been, powerfully contributed to relax still more the bond of national unity which even from the first was loose. Through the influence of Hellenic habits a deep schism took place in the Samnite stock. The civilized "Philhellenes" of Campania were accustomed to tremble like the Hellenes themselves before the ruder tribes of the mountains, who were continually penetrating into Campania and disturbing the degenerate earlier settlers. Rome was a compact state, having the strength of all Latium at its disposal; its subjects might murmur, but they obeyed. The Samnite stock was dispersed and divided; and, while the confederacy in Samnium proper had preserved unimpaired the manners and valour of their ancestors, they were on that very account completely at variance with the other Samnite tribes and towns.

In fact, it was this variance between the Samnites of the plain and the Samnites of the mountains that led the Romans over the Liris. The Sidicini in Teanum, and the Campanians in Capua, sought aid from the Romans (411) against their own countrymen, who in swarms ever renewed ravaged their territory and threatened to establish themselves there. When the desired alliance was refused, the Campanian envoys made offer of the submission of their country to the supremacy of Rome: and the Romans were unable to resist the bait. Roman envoys were sent to the Samnites to inform them of the new acquisition, and to summon them to respect the territory of the friendly power. The further course of events can no longer be ascertained in detail[20]; we discover only that - whether after a campaign, or without the intervention of a war - Rome and Samnium came to an agreement, by which Capua was left at the disposal of the Romans, Teanum in the hands of the Samnites, and the upper Liris in those of the Volscians.

The consent of the Samnites to treat is explained by the energetic exertions made about this very period by the Tarentines to get quit of their Sabellian neighbours. But the Romans also had good reason for coming to terms as quickly as possible with the Samnites; for the impending transition of the region bordering on the south of Latium into the possession of the Romans converted the ferment that had long existed among the Latins into open insurrection. All the original Latin towns, even the Tusculans who had been received into the burgess-union of Rome, took up arms against Rome, with the single exception of the Laurentes, whereas of the colonies founded beyond the bounds of Latium only the old Volscian towns Velitrae, Antium, and Tarracina adhered to the revolt. We can readily understand how the Capuans, notwithstanding their very recent and voluntarily offered submission to the Romans, should readily embrace the first opportunity of again ridding themselves of the Roman rule and, in spite of the opposition of the optimate party that adhered to the treaty with Rome, should make common cause with the Latin confederacy, whereas the still independent Volscian towns, such as Fundi and Formiae, and the Hernici abstained like the Campanian aristocracy from taking part in this revolt. The position of the Romans was critical; the legions which had crossed the Liris and occupied Campania were cut off by the revolt of the Latins and Volsci from their home, and a victory alone could save them. The decisive battle was fought near Trifanum (between Minturnae, Suessa, and Sinuessa) in 414; the consul Titus Manlius Imperiosus Torquatus achieved a complete victory over the united Latins and Campanians. In the two following years the individual towns, so far as they still offered resistance, were reduced by capitulation or assault, and the whole country was brought into subjection. The effect of the victory was the dissolution of the Latin league. It was transformed from an independent political federation into a mere association for the purpose of a religious festival; the ancient stipulated rights of the confederacy as to a maximum for the levy of troops and a share of the gains of war perished as such along with it, and assumed, where they were recognized in future, the character of acts of grace. Instead of the one treaty between Rome on the one hand and the Latin confederacy on the other, there came at best perpetual alliances between Rome and the several confederate towns. To this footing of treaty there were admitted of the old-Latin places, besides Laurentum, also Tibur and Praeneste, which however were compelled to cede portions of their territory to Rome. Like terms were obtained by the communities of Latin rights founded outside of Latium, so far as they had not taken part in the war. The principle of isolating the communities from each other, which had already been established in regard to the places founded after 370[21], was thus extended to the whole Latin nation. In other respects the several places retained their former privileges and their autonomy. The other old-Latin communities as well as the colonies that had revolted lost - all of them - independence and entered in one form or another into the Roman burgess-union. The two important coast towns Antium (416) and Tarracina (425) were, after the model of Ostia, occupied with Roman full-burgesses and restricted to a communal independence confined within narrow limits, while the previous burgesses were deprived in great part of their landed property in favour of the Roman colonists and, so far as they retained it, likewise adopted into the full burgess-union. Lanuvium, Aricia, Momentum, Pedum became Roman burgess-communities after the model of Tusculum[22]. The walls of Velitrae were demolished, its senate was ejected en masse and deported to the interior of Roman Etruria, and the town was probably constituted a dependent community with Caerite rights[23]. Of the land acquired a portion - the estates, for instance, of the senators of Velitrae - was distributed to Roman burgesses: with these special assignations was connected the erection of two new tribes in 422. The deep sense which prevailed in Rome of the enormous importance of the result achieved is attested by the honorary column, which was erected in the Roman Forum to the victorious dictator of 416, Gaius Maenius, and by the decoration of the orators' platform in the same place with the beaks taken from the galleys of Antium that were found unserviceable. Complete Submission of the Volscian and Campanian Provinces In like manner the dominion of Rome was established and confirmed in the south Volscian and Campanian territories. Fundi, Formiae, Capua, Cumae, and a number of smaller towns became dependent Roman communities with self-administration. To secure the pre-eminently important city of Capua, the breach between the nobility and commons was artfully widened, the communal constitution was revised in the Roman interest, and the administration of the town was controlled by Roman officials annually sent to Campania.  The same treatment was measured out some years after to the Volscian Privernum, whose citizens, supported by Vitruvius Vaccus a bold partisan belonging to Fundi, had the honour of fighting the last battle for the freedom of this region; the struggle ended with the storming of the town (425) and the execution of Vaccus in a Roman prison. In order to rear a population devoted to Rome in these regions, they distributed, out of the lands won in war particularly in the Privernate and Falernian territories, so numerous allotments to Roman burgesses, that a few years later (436) they were able to institute there also two new tribes. The establishment of two fortresses as colonies with Latin rights finally secured the newly won land. These were Cales (420) in the middle of the Campanian plain, whence the movements of Teanum and Capua could be observed, and Fregellae (426), which commanded the passage of the Liris. Both colonies were unusually strong, and rapidly became flourishing, notwithstanding the obstacles which the Sidicines interposed to the founding of Cales and the Samnites to that of Fregellae. A Roman garrison was also despatched to Sora, a step of which the Samnites, to whom this district had been left by the treaty, complained with reason, but in vain. Rome pursued her purpose with undeviating steadfastness, and displayed her energetic and far-reaching policy - more even than on the battlefield - in the securing of the territory which she gained by enveloping it, politically and militarily, in a net whose meshes could not be broken.
