Oligarchy implies rulership by a few powerful individuals. It is a system of government where a small group of people holds all the power and control over a country or organization. The word "oligarchy" comes from the Greek words "oligos," meaning "few," and "arkhein," meaning "to rule." In an oligarchic system, the ruling class may come from a specific social, economic, or political background, and they often use their power to maintain their privileged position and control the resources of the state.
