The Tribunes of the Plebs were elected officials in ancient Rome who represented the interests of the common people, known as the plebeians. Established in 494 BCE, these tribunes had the power to veto decisions made by the Senate and other magistrates, ensuring that the rights of the plebeians were protected against the more powerful patrician class. Each tribune was sacrosanct, meaning that harming them was a serious offense. They could also convene the Council of the Plebs, allowing them to propose legislation. Over time, the role of the tribunes evolved, becoming influential in Roman politics and contributing to the balance of power in the Republic.
