The North Korean cult of personality surrounding its ruling family, the Kim family, has existed in North Korea for decades and can be found in many examples of North Korean culture. Although not officially recognized by the North Korean government, many defectors and Western visitors claim there are often stiff penalties for those who criticize or do not show "proper" respect for the regime. The personality cult began soon after Kim Il-sung took power in 1948, and was greatly expanded after his death in 1994.
While other countries have had cults of personality to various degrees (such as Joseph Stalin's in the Soviet Union), the pervasiveness and extreme nature of North Korea's personality cult surpasses that of Stalin or Mao Zedong. The cult is also marked by the intensity of the people's feelings for and devotion to their leaders, and the key role played by a Confucianized ideology of both in maintaining the cult and thereby in sustaining the regime itself.
The cult of personality surrounding the Kim family requires total loyalty and subjugation to the Kim family and establishes the country as a one-man dictatorship through successive generations. The 1972 constitution of North Korea incorporates the ideas of Kim Il-sung as the only guiding principle of the state and his activities as the only cultural heritage of the people. According to New Focus International, the cult of personality, particularly surrounding Kim Il-sung, has been crucial for legitimizing the family's hereditary succession, and Yong-soo Park noted in the Australian Journal of International Affairs that the "prestige of the Suryong [supreme leader] has been given the highest priority over everything else in North Korea".
Kim Il-sung developed the political ideology of the Juche idea, generally understood as self-reliance, and further developed it between the 1950s and the 1970s. Juche became the main guide of all forms of thought, education, culture and life throughout the nation until Kim Jong-il introduced the Songun (military-first) policy, which augments the Juche philosophy and has a great impact on national economic policies.
