The first known reference to Juche as a North Korean ideology was an anti-Soviet speech given by Kim Il-sung on December 28, 1955. Titled "On Eliminating Dogmatism and Formalism and Establishing Juche in Ideological Work", it was given to promote a political purge similar to the earlier Yan'an Rectification Movement in China.[2] The process for the development of Juche followed a process similar to China's development of Zili Gengsheng, in that both came from a doubt in the benefits of being in the Soviet orbit, and that both ideologies stimulated a turn towards the Third World in foreign policy
