The tribunes in the conflict of the orders In 471 BC the
Lex Publilia transferred the election of the tribunes from
comitia curiata to the
comitia tributa, thus removing the influence of the patricians on their election. In 462, the tribune
Gaius Terentillius Arsa alleged that the consular government had become even more oppressive than the monarchy that it had replaced. He urged the passage of a law appointing five commissioners to define and limit the powers of the consuls. By threat of war and plague, the issue was postponed for five contentious years, with the same college of tribunes elected each year. In 457, hoping to deprive the law's supporters of their impetus, the senate agreed to increase the number of tribunes to ten, provided that none of the tribunes from the preceding years should be re-elected. However, the new tribunes continued to press for the adoption of Terentillus' law, until in 454 the senate agreed to appoint three commissioners to study Greek laws and institutions, and on their return help to resolve the strife between the orders. On the return of the envoys, the senate and the tribunes agreed to the appointment of a committee of ten men, known as the
decemviri, or decemvirs, to serve for one year in place of the annual magistrates, and codify Roman law. The tribunate itself was suspended during this time. But when a second college of decemvirs appointed for the year 450 illegally continued their office into the following year, and the abuses of their authority became clear to the people, the decemvirate was abolished and the tribunate restored, together with the annual magistrates. Among the laws codified by the decemvirs was one forbidding intermarriage between the patricians and the plebeians; the
Twelve Tables of Roman law also codified that the consulate itself was closed to the plebeians. Worse still, in 448, two patricians were co-opted to fill vacant positions in the tribunate, although they proved to be of moderate views, and their year of office was peaceful. To prevent future attempts by the patricians to influence the selection of tribunes,
Lucius Trebonius Asper promulgated
a law forbidding the tribunes to co-opt their colleagues, and requiring their election to continue until all of the seats were filled. But relations between the orders deteriorated, until in 445, the tribunes, led by
Gaius Canuleius, were able to push through
a law permitting the intermarriage of patricians and plebeians, and allowing one of the consuls to be a plebeian. Rather than permit the election of a plebeian consul, the senate resolved upon the election of
military tribunes with consular power, who might be elected from either order. Initially this compromise satisfied the plebeians, but in practice only patricians were elected. The regular election of military tribunes in the place of consuls prevented plebeians from assuming the highest offices of state until the year 400, when four of the six military tribunes were plebeians. Plebeian military tribunes served in 399, 396, 383, and 379, but in all other years between 444 and 376 BC, every consul or military tribune with consular powers was a patrician. Beginning in 376,
Gaius Licinius Calvus Stolo and
Lucius Sextius Lateranus, tribunes of the plebs, used the veto power to prevent the election of any annual magistrates. Continuing in office each year, they frustrated the patricians, who, despite electing patrician military tribunes from 371 to 367, finally conceded the consulship, agreeing to the
Licinian Rogations. Under this law, military tribunes with consular power were abolished, and one of the consuls elected each year was to be a plebeian. Although this law was occasionally violated by the election of two patrician consuls, Sextius himself was elected consul for 366, and Licinius in 364. At last, the plebeian tribunes had broken the patrician monopoly on the highest magistracies of the state. Following their victory in 367, the tribunes remained an important check on the power of the senate and the annual magistrates. In 287 BC, the senate formally recognized the
plebiscita as laws with binding force. Former tribunes were once again
admitted to the annual magistracies beginning in 75 BC, and the tribunician authority was fully restored by the consuls
Gnaeus Pompeius Magnus and
Marcus Licinius Crassus in 70. In 48 BC, the senate bestowed the
tribunicia potestas (tribunician power) on the dictator
Gaius Julius Caesar, who, as a patrician, was ineligible to be elected one of the tribunes. When two of the elected tribunes attempted to obstruct his actions, Caesar had them impeached, and taken before the senate, where they were deprived of their powers. Never again did Caesar face opposition from the tribunes; he held the tribunician power until his death in 44. In 23 BC, the senate bestowed the tribunician power on Caesar's nephew,
Octavian, now styled
Augustus. From this point, the
tribunicia potestas became a pre-requisite for the emperors, most of whom received it from the senate upon claiming the throne, though some had already received this power during the reigns of their predecessors; the granting of this authority was a means of designating a favoured member of the imperial court as the emperor's intended successor.
Agrippa,
Drusus the Younger,
Tiberius,
Titus,
Trajan, and
Marcus Aurelius each received the tribunician power in this way. With the regular assumption of the tribunician power by the emperors and their heirs, the ancient authority of the tribunes dwindled away. Although the office of tribune endured throughout
imperial times, its independence and most of its practical functions were lost. Together with the aedileship, it remained a step in the political career of many plebeians who aspired to sit in the senate, at least until the third century. There is evidence that the tribunate continued to exist as late as the fifth century AD. ==See also==
