The history of the people of Rome can be recorded in prehistoric times, and likewise the death of Emperor Constantine of 337 AD. It can be divided into three main sectors, monarchy, republic and empire. (Star, ancient Romans) The system and trend of creation and development in Rome during the monarchy was very important for the future life of the people of Rome. Trends such as handling of families, concepts of private property, social and political systems, laws, and ultimately religion.
Following the history of the Roman government, you can see that the first form of governance is monarchy. This means that the king will dominate the masses of people. But by 510 BC, with the elimination of the monarchy, the two territories recognized two equal consulss, enabling a new power distribution process. These consular services serve in a highly authoritative position and regularly handle military and legal affairs, and public affairs. As described in Polybius's "World History" 12.1-9, "Consular offenses are responsible for taking these (public service), opening a rally, leading a resolution, and enforcing the order of people." Because there are many obligations, the government is planning to divide it further, including the magistrate's court.
In his political work Aristotle first mentioned the idea of "mixed government" or "mixed government" and borrowed many constitutional forms of ancient Greek city states. In the Republic of Rome, Roman Senator, Consul and Congress published an example of a mixed government based on Polybius (History, pages 6, 11-13). John Calvin (1509-1564) supports dividing political power into government systems between democracy and aristocracy (mixed government). Calvin appreciated the advantages of democracy and said, "If God allows people to elect their own government and local judges it would be a very valuable gift." These agencies complement each other and need to be controlled by a check and balance system.
