Why do you think at least one of the censors had to be a plebeian?

Having at least one plebeian among the censors ensured that the perspectives and interests of the common people were represented in the governance of the Roman Republic. This inclusion would help balance the power dynamics between the patricians and plebeians, promoting fairness and accountability in the administration. Additionally, it fostered trust in the political system, as plebeians could see their concerns reflected in decisions affecting public life. Ultimately, this arrangement aimed to strengthen the overall stability of the Republic by bridging class divides.
