The Tuscans, who had taken advantage of the Celtic attack on Rome to assail Veii, had accomplished nothing, because they had appeared in insufficient force; the barbarians had scarcely departed, when the heavy arm of Latium descended on the Tuscans with undiminished weight. After the Etruscans had been repeatedly defeated, the whole of southern Etruria as far as the Ciminian hills remained in the hands of the Romans, who formed four new tribes in the territories of Veii, Capena, and Falerii (367), and secured the northern boundary by establishing the fortresses of Sutrium (371) and Nepete (381). With rapid steps this fertile region, covered with Roman colonists, became completely Romanized. About 396 the nearest Etruscan towns, Tarquinii, Caere, and Falerii, attempted to revolt against the Roman encroachments, and the deep exasperation which these had aroused in Etruria was shown by the slaughter of the whole of the Roman prisoners taken in the first campaign, three hundred and seven in number, in the market-place of Tarquinii; but it was the exasperation of impotence. In the peace (403) Caere, which as situated nearest to the Romans suffered the heaviest retribution, was compelled to cede half its territory to Rome, and with the diminished domain which was left to it to withdraw from the Etruscan league, and to enter into the relationship of subjects to Rome which had in the meanwhile been constituted primarily for individual Latin communities. It seemed, however, not advisable to leave to this more remote community alien in race from the Roman such communal independence as was still retained by the subject communities of Latium; the Caerite community received the Roman franchise not merely without the privilege of electing or of being elected at Rome, but also subject to the withholding of self-administration, so that the place of magistrates of its own was as regards justice and the census taken by those of Rome, and a representative (-praefectus-) of the Roman praetor conducted the administration on the spot--a form of subjection, which in state-law first meets us here, whereby a state which had hitherto been independent became converted into a community continuing to subsist -de jure-, but deprived of all power of movement on its own part. Not long afterwards (411) Falerii, which had preserved its original Latin nationality even under Tuscan rule, abandoned the Etruscan league and entered into perpetual alliance with Rome; and thereby the whole of southern Etruria became in one form or other subject to Roman supremacy. In the case of Tarquinii and perhaps of northern Etruria generally, the Romans were content with restraining them for a lengthened period by a treaty of peace for 400 months (403).
