Ideocracy
Ideocracy (a portmanteau word combining "ideology" and kratos, Greek for "power") is "governance of a state according to the principles of a particular (political) ideology; a state or country governed in this way". It is government based on a monistic ideology—as distinct from an authoritarian state which is characterized by strong central power and limited political freedoms. An ideocratic state can either be totalitarian—citizens being forced to follow an ideology—or populist (citizens voluntarily following an ideology).
