There is one thing you can always be sure of regarding power in government—somebody has it. It may be an entire group or just one leader, but you will not find a society where power is absent. Who has the power, why they have it, and how it is used depend on many different factors. And these factors create the political system of a country.
The Feudal System
After the Roman Empire fell, Europe was a mess. Law and order had disappeared, and money was no longer used to buy things. Roads, cities, and bridges fell into disrepair. People did whatever they wanted, and there was no government to keep order. It was a harsh world.
Finally, a series of kings rose up and took control, one after the other. Whenever a king or queen has unrestricted rule of country, the political system is called a monarchy.
