But in the moment of triumph news came that Etruria was in arms. The Etruscans hoped by a brave effort to recover the territory which the Romans had for the second time appropriated. A force was sent against them; but so completely was it routed on the nones of July, that this day was noted in the Calendar as the Poplifugia. Siege was then laid to Sutrium by the victors, and it fell. But the prompt dictator, on the first alarm, marched his troops straight from Bola to the point of danger; and on the very day on which Sutrium had yielded to the foe, it was again taken by the Roman general. Thus Camillus again appears as the saviour of Rome. He enjoyed a threefold triumph over the Volscians, the Æquians, and the Etrurians. It was two years after, that the Etruscan territory, now effectually conquered, was formed into four tribes. By the addition of these new tribes, the first that had been added since this very territory had been wrested from Rome by Porsenna, the whole number was raised to twenty-five. The late assault of the Etruscans, perhaps, suggested the wisdom of making the free inhabitants of this district citizens of Rome. Men who had lately been subject to the oppressive government of a civic oligarchy, being now mingled with Roman plebeians who had received allotments in the district, and seeing the comparative freedom of all Roman burgesses, were sure to fight for Rome rather than join in an insurrection against her. Here was the beginning of that sagacious policy, which for a time led political enfranchisement hand in hand with conquest. Thirty years later (358 B.C.) the senate pursued the same course with respect to the Pontine district and other lowlands which had been recovered from the grasp of the Volscians. A settlement of poor plebeians, which was attempted in 387 B.C., failed; the emigrants were cut off by the Volscian hills-men. But the territory being now formed into two tribes, so as to make the whole number twenty-seven, the inhabitants had an interest in repressing predatory inroads. [Sidenote: [387-354 B.C.]] Soon after followed the struggle for the Licinian laws; and during this period the annals are altogether silent on the subject of wars.
