I believe you mean Theocracy - that is a government system that recognizes a deity as the supreme ruler, or sometimes by a group of individuals who are thought to have a direct line of communication with a deity.
Theocracy is a form of government in which religious leaders hold political power and rule in the name of a deity or divine authority. In a theocracy, laws and governance are based on religious principles and interpretations of sacred texts. Examples of theocracies include the Vatican City and historical periods such as the rule of the Taliban in Afghanistan.
Iran and Vatican City are theocracies.
The Etruscan government style changed from total monarchy to oligarchic democracy (as the Roman Republic) in the 6th century BC.
Iran, Vatican City, and Saudi Arabia are examples of countries that are considered theocracies, where religious leaders hold significant political power and influence government policies based on religious principles.
The squeakiest wheel gets the oil. We strive to keep Seperation of Church and State as law. If suddenly tomorrow your government said you country was governed by God and the Church you could be exiled, punished, or murdered for not believing the way they say to believe. I guarantee you if the USA became a theoracy, people would die or disappear.
