Propaganda represents a deliberate and systematic attempt to create mass perception by non-ethnic means, to manipulate with the knowledge of masses and to focus their behavior in order to achieve the effect of a propagandist's intentions. Political propaganda is most often associated with totalitarian regimes and their leaders. North Korea is the last totalitarian country of the 21st century. The political elites in that country are directing most of their resources on creating and spreading propaganda messages to ensure the population's affection and to retain power in their hands. The paper gives an overview of North Korea's propaganda activities. By analyzing the state ideology, the cult of personality, film art, and the Internet, the propaganda activities of the North Korean government have been summed up, from the early days of this country to the present day. The author sums up the needs and modalities of the use of propaganda techniques by the North Korean government, to create and preserve an isolated social community in which it is possible to ensure the existence of non-democratic government and control, over the people of that country.
