A "plebeian" refers to a commoner in ancient Rome, distinguishing them from the elite class known as the patricians. Plebeians made up the majority of the population and included farmers, laborers, and artisans. They had limited political power and often struggled for rights and representation in the Roman government. Over time, plebeians gained more influence, especially after the Conflict of the Orders, a power struggle between the plebeians and patricians. This led to the establishment of the Tribunes, officials who represented plebeian interests. The term "plebeian" has since evolved to describe common people in various contexts, often implying a lack of sophistication or refinement.
