Tribunician power was a significant political authority in ancient Rome, primarily associated with the office of the tribune of the plebs. This power allowed tribunes to represent the interests of the plebeians, propose legislation, and veto decisions made by other magistrates or the Senate, ensuring protection against arbitrary actions by patricians and officials. In the context of the Age of Augustus, this power was pivotal as it contributed to the consolidation of Augustus' authority while maintaining a semblance of traditional republican governance.
