Oligarchy is a form of governance in which power is concentrated in the hands of a small, elite group of individuals or families. This ruling class often holds significant economic, social, or political influence, allowing them to control decision-making processes and resources. Oligarchies can arise in various contexts, including political systems, corporations, and even social organizations, and they may operate alongside other forms of government, such as democracy or autocracy. The concentration of power can lead to inequality and limit broader participation in governance.
