Kim Jong-suk
The main influence in North Korea has been since 1996, the notion of "The Red Banner Spirit". This system of belief encourages the North Korean people to build a "kangsong taeguk", a fortress state, based on self-reliance and absolute loyalty to the leader (suryong). This philosophy was created by the "three generals of Mt. Paektu," referring to former North Korean leader Kim Jong-il, his father Kim Il-sung and his natural mother Kim Jong-suk. Again little is known of philosophical publications on this subject; but it appears to have replaced Marxism with a home-grown nationalistic ideology.
