Roman citizens were individuals who held legal rights and privileges in ancient Rome. They could participate in government, own property, and marry other citizens. Citizenship was highly valued and could be granted to free men from various regions, including conquered territories, as Rome expanded its influence. The status of a Roman citizen came with responsibilities, such as paying taxes and serving in the military. There were different classes of citizens, including the patricians, who were wealthy and powerful, and the plebeians, who were common people. Over time, citizenship became more accessible, allowing a broader segment of the population to enjoy its benefits.
