State within a state
State within a state is a political situation in a country when an internal organ ("deep state"), such as the armed forces and civilian authorities (intelligence agencies and police), does not respond to the civilian political leadership. The term, like many in politics, derives from the Greek language (κράτος εν κράτει, kratos en kratei, later adopted into Latin as imperium in imperio or status in statu).
Sometimes, the term refers to state companies that, though formally under the command of the government, act de facto like private corporations. Sometimes, the term refers to companies that, though formally private, act de facto like "states within a state".
Certain political debates surrounding the separation of church and state revolve around the perception that if left unchecked, the Church might turn into a kind of State within a State, an illegitimate outgrowth of the State's natural civil power.
Imperium in imperio was also the first state motto of Ohio, reflecting its great size and influence within the early United States. The motto proved unpopular and was replaced two years later.
