By expanding Rome, this made Rome more powerful and closer to become a world dominator. The Ius Civile was the creation of a single unified code of Roman law the was written by Julius Caesar. The science of law is one of the few original creations of Roman literature. The earliest legal code of the Republic was the Law of the Twelve Tables and its general aim was to equate human law with that of nature by developing an objective system of natural justice.
