Who wrote the ancient rome law of nations?

Answer 1

The law of nations was an expression the Romans used for the rules that regulated relations between different peoples/states. An example of this was the rule that ambassadors were not to interfere with the internal politics of the places they were sent to for their embassies.

Answer 2

Nobody wrote the Law of nations (jus gentium). It was a concept, rather than a written law.

Nation was the Latin word for ethnicity/ethnic group and just gentium was a sort of natural law which was regarded as "innate in every human being." Roman law was based on the concept of rights. Jus meant rights. Although the rights of citizenship were reserved to Roman citizens, other rights were seen as held by all persons. This was based on the notion that the concept of justice sprung from the human mind rather than ethnicity and that it applied regardless of citizenship. Through this, the provincials (conquered peoples) of the Roman Empire could enjoy the protection of Roman civil law in their dealings with Roman citizens. Cases between Romans and non-Romans were adjudicated by the praetor peregrino, the chief justice for foreigners, who was supposed to base his rulings on fairness and on Roman civil law.

Answer 3

The Roman's law of nations (jus gentium) originated form the principle of natural law. Nation was the Latin word for ethnicity and jus gentium was a sort of natural law in that it was regarded as innate in every human being. Roman law was based on the principle of rights (jus means rights). The rights conferred by jus gentium were considered to be held by all persons. They were based on the notion that the concept of justice sprung from the human mind rather than ethnicity and that it applied to everyone, regardless of citizenship or ethnicity. Through this, the provincials (the conquered peoples) and the citizens of the client states of Rome enjoyed the protection of Roman civil law in their dealings with Roman citizens. Cases between Romans and non-Romans were adjudicated by the praetor peregrino, the chief justice for foreigners, who was supposed base his rulings on fairness and on Roman civil law under the principle of the jus gentium. The law of nations within the Roman Empire became redundant in 215 A.D. when the emperor Caracalla extended Roman citizenship to all freeborn men in the empire.
