Extension of Roman Citizenship

The Constitutio Antoniniana was an edict issued by Emperor Caracalla that granted Roman citizenship to nearly all free inhabitants of the Roman Empire. This decree marked a significant expansion of rights and legal status beyond the previously restricted citizenry.

The motive behind the edict included unifying the empire under a common identity and increasing tax revenues. The extension of citizenship had lasting impacts on social structure, law, and military recruitment within the Roman world.
