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.
