The Romans were the 1st to devise the concept of citizen where it applied to a civil society. ALL definitions whether natural or feudal derived their core foundations on Roman law. The term subject was derived when tribes were conquered and the King became the only sovereign. The subjects were stripped of all natural rights but those that the King or Prince allowed them to retain & the right to remove themselves and become members of another society was NOT one of them, hence the birth of perpetual allegiance. The Republics formed of free citizens were threatening to the feudal kings & princes. They were power hungry & greedy to own all lands. Subjects never really own their land, they merely rent it from the central sovereign.
