An oligarchy is a form of government in which power is concentrated in the hands of a small group of individuals or families. This elite group typically holds significant influence over political, economic, and social decisions, often prioritizing their own interests over those of the broader population. Oligarchies can arise in various contexts, including politics, business, or social structures, and may exist alongside other forms of governance. Examples include certain historical regimes and contemporary political systems where a few individuals exert disproportionate control.
