Why were Rome's patricians so concerned when the plebeians elected their own council?

Rome's patricians were concerned when the plebeians elected their own council, known as the Tribune of the Plebs, because it represented a shift in power dynamics that threatened their elite status and control over the Roman political system. The plebeians, who were the common citizens, gained a voice to advocate for their interests and challenge patrician authority, which could lead to significant social and political reforms. This development heightened fears among patricians of losing their privileges and influence, potentially destabilizing the traditional hierarchies in Roman society.
