The form of government that has a small group of leaders is called an oligarchy. In an oligarchy, power is held by a few individuals or a small elite group. These leaders often come from a specific social or economic class and make decisions that affect the entire population. There are different types of oligarchies, such as aristocracy, where power is held by a hereditary ruling class based on noble birth, or a plutocracy, where power is held by wealthy individuals or corporations. In these systems, the leaders may have varying degrees of control and influence over the government and its policies. For example, in ancient Greece, the city-state of Sparta was governed by an oligarchy. The state was ruled by two kings who were advised by a council of elders. The citizens had limited political rights, and power was concentrated in the hands of a small group of nobles. In modern times, countries like Russia and China have been described as having elements of oligarchy, where a small group of powerful individuals control key sectors of the economy and politics. It is important to note that an oligarchy can be seen as a form of government that is not based on the principles of democracy, where power is distributed among the people. Oligarchies can limit individual freedoms and may not prioritize the needs and interests of the general population.
