In Ancient Rome, a civitas (Latin pronunciation: [ˈkiːwɪtaːs]; plural civitates), sometimes translated as "city", was the social body of the cives, or citizens, united by their laws, which gave them responsibilities (Latin: munera) on the one hand, and rights on the other. The agreement (concilium) has a life of its own, creating a res publica or "public entity" (synonymous with civitas), into which individuals are born or accepted, and from which they die or are ejected. The civitas is not just the collective body of all the citizens; it is the contract binding them all together, because each of them is a civis.
