How were oligarchy and tranny different?

Oligarchy and tyranny represent different forms of governance. An oligarchy is ruled by a small group of individuals or families who hold power, often based on wealth, social status, or military control, and their decisions may reflect the interests of the elite rather than the general population. In contrast, tyranny is characterized by the absolute rule of a single leader who wields power in an oppressive manner, often disregarding laws and ruling without consent from the governed. While both can lead to the suppression of individual rights, oligarchies may allow for some degree of elite competition, whereas tyranny typically involves unilateral decision-making by one person.
