A system of government in which priests rule in the name of God or a god is termed a theocracy. Governmental power is held by religious leaders, who claim divine guidance. Laws and policies are based on religious doctrines and principles. Vatican City and Iran serve as contemporary examples, illustrating differing interpretations and implementations of this governance model.
This form of government significantly shapes cultural landscapes, influencing everything from architecture and dress codes to legal systems and educational curricula. Historically, many societies have organized themselves under theocratic rule, impacting geopolitical dynamics and societal norms. Understanding this concept is crucial for analyzing political systems, cultural practices, and historical developments across various regions.
