Roman Citizenship was a privileged status granted to individuals in ancient Rome, providing them with specific legal rights and protections. Citizens could participate in government, own property, and marry other citizens. They were also subject to Roman law and could appeal to the courts. Initially, citizenship was limited to residents of Rome and its surrounding areas, but over time, it expanded to include people from conquered territories. The Constitutio Antoniniana in 212 AD granted citizenship to all free inhabitants of the Roman Empire, further integrating diverse cultures and communities into Roman society.
