The least likely type of government in the early Greek poleis was theocracy. While theocracy involves rule by religious leaders and is characterized by religious authority, early Greek city-states (poleis) were more commonly governed by forms such as aristocracy, monarchy, oligarchy, and democracy, which were primarily based on political or social structures rather than religious ones.
