North Korea has been ruled as a single-party communist state led by a dictator since 1948. It follows the Juche and Songun ideologies of self-reliance and military-first policy. The country has a centrally planned economy that was heavily dependent on aid from the Soviet Union and China, but it collapsed in the 1990s causing widespread famine. North Korea has a strong military and pursues nuclear weapons, which has led to international sanctions. The society emphasizes universal healthcare and education, but the government strictly controls all aspects of life and human rights abuses are widespread.
