Theocracy is a form of government in which one or more deities are recognized as supreme ruling authorities, giving divine guidance to human intermediaries who manage the government's daily affairs.
The word theocracy originates from the θεοκρατία (theocratia) meaning "the rule of God". This, in turn, derives from θεός (theos), meaning "god", and κρατέω (krateo), meaning "to rule". Thus the meaning of the word in Greek was "rule by god(s)" or human incarnation(s) of god(s).
The term was initially coined by Flavius Josephus in the first century AD to describe the characteristic government of the Jews. Josephus argued that while mankind had developed many forms of rule, most could be subsumed under the following three types: monarchy, oligarchy, and democracy. However, according to Josephus, the government of the Jews was unique. Josephus offered the term "theocracy" to describe this polity in which a god was sovereign and the god's word was law.
Josephus' definition was widely accepted until the Enlightenment era, when the term took on negative connotations and was barely salvaged by Hegel's commentary. The first recorded English use was in 1622, with the meaning "sacerdotal government under divine inspiration" (as in ancient Israel and Judah); the meaning "priestly or religious body wielding political and civil power" was first recorded in 1825.
The term theocracy derives from the Koine Greek θεοκρατία, "rule of God", a term used by Josephus for the kingdoms of Israel and Judah, reflecting the view that "God himself is recognized as the head" of the state. The common, generic use of the term, as defined above in terms of rule by a church or analogous religious leadership, may be more accurately described as an ecclesiocracy.
In a pure theocracy, the civil leader is believed to have a personal connection with the deity or deities of that civilization's religion or belief, such as Muhammad's leadership of the early Muslims with prophecies from Allah.
