Question

Looking for a reasonably official Word or phrase for Ideology /political system of a country, whose governing bodies keeps tight control of its media, its internal affairs and does not let any interference whether human rights or international pressure on their self serving policies. Where laws are passed by parliament tightening media control. Mishandling in the country is beyond scrutiny from outside (international) forces. Pretty much everything is insulated as in "insulated country"

An '...ism' or '...logy' or "...cracy" or "insulated country" like listed word or listed phrase. I believe dictatorship could have been used. But it is rather outsider pressure which is intolerated while internally there is either amicable agreement owing to plain cultural similarities or simply forced cultural obedience typically like a monarchy.

Answer 2

Authoritarianism.

According to Wikipedia, authoritarianism is "a form of government characterized by the rejection of political plurality, the use of a strong central power to preserve the political status quo, and reductions in the rule of law, separation of powers, and democratic voting."

A government that controls its media to this sort of extent is definitely using a strong central power to preserve the political status quo along with a reduction in the rule of law and separation of powers.
