measures as well as the senate. In 310, the plebeians mustered courage to demand that one of the consuls should thenceforward be chosen from their order. To divert them from this, the patricians yielded to another demand—the repeal of the law prohibiting intermarriage between the two orders. The plebeians, however, still persisting in their demand regarding the consulship, the patricians, in 311, offered a compromise, which consisted in breaking down the supreme authority, hitherto concentrated in the consulship, into three offices—the Censorship, the Quæstorship, and the Military Tribunate—with consular powers. The censors were to be two in number, chosen for a period of five years, by the curies from among the patricians, subject to the approval of the centuries. The ostensible duty of the censors was the administration of the public revenues; but as they were intrusted with the task of determining the rank of every citizen, and of rating his taxable property, their power was, in reality, enormous. To watch over the moral conduct of the citizens, and to degrade such senators or knights as disgraced their order, were parts of their understood duty. The quæstors, two in number, were to keep the public accounts; they were likewise to be patricians, but were to be chosen by the centuries. Regarding the third office, the military tribunate, the plebeians were to have the option of this office, consisting of an indefinite number of persons of somewhat less dignity than the consuls, but to be chosen by the centuries from either order indiscriminately, or of consuls to be chosen, as before, from among the patricians only.
This compromise having been accepted, the period from 311 to 350 was one of incessant agitation on the part of the plebeians, of incessant opposition on the part of the patricians, of incessant shifting between the consulship and the military tribunate, according as the patricians or the plebeians were the stronger. On the whole, however, the plebeians gained ground. In 321, the active authority of the censors was limited to eighteen months out of the five years for which they were appointed. In 328, the tribes obtained the right of deliberating on questions of peace and war. In 334, the number of the quæstors was increased to four, to be chosen indiscriminately from either order. Lastly, in 350, or B. C. 404, the system of payment for military service became common. During these forty years the patricians had frequently had recourse to the expedient of appointing a Dictator, or supreme magistrate, with unlimited authority for six months. Such an appointment almost always proved a temporary check to the political advancement of the plebeians. In cases of difficulty also, arising from external danger, it was usual to appoint some able man dictator; and it was at such a juncture, in the year 359, that, determined to bring the siege of Veii to a close, the Romans appointed Camillus to this high office.
The siege of Veii having terminated so successfully, the Romans were prepared to resume their career of conquest without, and their political agitations within, when both the one and the other received a check from an unexpected quarter. Some cause, now unknown, had thrown the Gauls, or Celtic populations inhabiting the western portion of Central Europe, into commotion; and bursting from their native haunts, a mass of these savages crossed the Alps in quest of plunder and settlements, established a permanent abode in the country adjacent to the Po, and pushed their destructive way through almost the whole length of the peninsula.
