The decemvirs were forcibly overthrown before the close of their second year in office. The stories as to the cause are not only conflicting but diametrically so. According to one historical theory, the rebellion against the decemvirs began among the plebeians on account of the oppression which they suffered from the hands of these men; while, on the other hand, it is believed by many historians that the decemvirs were overthrown by the patricians because they were giving too many concessions to the plebeians. Whatever the cause, the power of the decemvirs was taken from them and all the former Roman officials and assemblies were reëstablished, with the old powers and jurisdictions. The "Law of the Twelve Tables," which the decemvirs had drawn up, however, remained for centuries as the great basis of Roman law.
Five years after the deposition of the decemvirs the tribune Canuleius secured the passage by the comitia tributa of the Canuleian Law, which marked another milestone passed by the plebeians in their march toward equality before the law.
Two great concessions were given by this act, one in the field of private and the other in the field of public law. The law which had existed from the earliest days in Rome, and which had been incorporated in the "Law of the Twelve Tables," prohibiting intermarriage between plebeians and patricians, was abolished. It was also provided that any year the people, instead of electing consuls, might elect military tribunes, who should possess all the powers, although not all the dignities, of the consuls. Either patricians or plebeians could be elected to the office of military tribunes.
The election of military tribunes was authorized by law many years before any such officials were elected in Rome; but the fear that the consular power might sometime fall into the hands of a plebeian induced the patricians in 443 B.C. to secure the passage of a law for the creation of new officials who should possess some of the powers previously held by the consul and who must be chosen from the patrician order.
These new officials, called censors, were to be two in number and were to be elected every five years. At first these officials held office until the time arrived for the election of their successors, but later their term of office was limited to one year and a half, there thus being three and one half years out of every five-year period when this office was in abeyance.
The most important duty given to the censors at the outset seems to have been the authority of filling vacancies in the Senate as it became necessary to keep the number up to the required three hundred. Up to this time this power of appointing senators had been exercised by the consul. As time went on, however, the powers of this office rapidly increased until at length it became the highest post of honor at Rome, the men elected censors being almost invariably former consuls or military tribunes.
The arbitrary power of inquisition over all the public affairs of Rome and the private conduct of the Roman citizens was so astonishingly great that we wonder how it could have existed without constant and gross abuses. In the later days of the republic the censors had the right to make a so-called "censorial note" of all Roman citizens, who, without having gone to the point of violating the criminal law, or at least without having been convicted of a crime, had been guilty of dishonorable or immoral conduct. All persons thus named suffered severe civic penalties. If the person were a senator he lost his seat in the Senate; if a knight, he lost the peculiar privileges belonging to this rank. In every case the person lost his membership in the association of his tribe and was subject to increased taxation.
The exclusive right to serve as censors was one of the last exclusive privileges retained by the patricians, the plebeians not being made eligible to this office until 339 B.C.
Although Rome was in an almost constant state of warfare during the fifth century before Christ, the conflicts were neither on a large scale nor decisive in their results. The chief enemies of Rome were the neighboring Latin and Etruscan cities, with one or another of whom Rome was almost constantly engaged in hostilities. At the beginning of the fourth century before Christ Rome was attacked by a new and more terrible enemy from the north, who very nearly changed the whole course of the world's history by wiping the city of Rome out of existence before its career of greatness had begun.
This enemy was the Gauls, who captured and burned Rome in the year 390 B.C., but who failed to take the citadel of the city and finally withdrew, either being driven away or bribed to depart. Not only are the details of the capture of Rome by the Gauls very uncertain, but by destroying all the old Roman records and many of the Roman monuments in their sack of Rome, the Gauls are responsible for much of the uncertainty which exists as to the truth of the details of the history of Rome prior to their invasion. In fact, it is generally considered that the authentic history of Rome begins only after 390 B.C., the history of the Roman kingdom being little more than mythology; while what we know of the Roman republic prior to 390 B.C. consists of an inseparable mixture of true history and legendary tales.
