Korean nationalist history had widened the position and faculty as the regime that regulate the traitors to the nation each other in South and North Korea due to the division into 2 regime in 1948 and the partition of the Korean peninsula in 1945. The North Korean historical group occupied it first, developed and grown the Korean nationalist history. However, the South Korean historical group didn't think the academic achievement of North Korean as the Korean nationalist history at all. This article reviews the achievement of historical study in North Korea as a fork of Korean nationalist history. It is also examines about the examples of nation, nationalist notions used in North Korea, and the procedures of appearance, competition and establishment, and the role of Korean nationalist history. As a result of this study, the regulation of national, nationalist notions in North Korea had changed depending on the situation and the policy of the Worker's Party of Korea. The North Korean historical group created the compilation committee of the Korean history in 1947 and tried to describe a national history rather than the class line. In this process, they could eradicate the vestiges of Japanese imperialist colonial history by making clear that there divided into the Old Stone Age, the Neolithic era and the Bronze Age in Korean peninsular. The North Korean historical group issued the Historical Science from 1955 and researched the formation of nation and periodization. They also tried to systemize logically the nationalist history based on the national theory focusing the lineage. The North Korean historical group criticized the limitation of the materialistic conception of history as revising the Korean history based on a history view of Juche from the 6th conference Worker's Party of Korea. However, they didn't apply a struggle of the people's independence to the description of history in ancient and middle ages. They aimed at fostering of North Korea nationalist history for respecting Kim Il-seong and DPRK. The historians lost their autonomy as a result of excessive interference for the historical studies and publication in this process. North Korea had tried to hard maintain their system since 1990. They clarified the Korea nation－first－principle in public as one of crisis breakthrough and historical group created new mythology and ancient history. The restoration of Dangun tomb and the civilization of Daedong River can be examples of that. The characteristic in the path of national history naturalization in North Korea is the formulation and balance of the category in ‘people' and ‘class' through the reformulation of concept as accepting national values, parallelism with class category → expand of nationalism content by emphasizing the leadership of popular mass → ‘true nationalism' regarding universal Marx-Leninist content and patriotism as a medium. The North nationalist history currently naturalized as a Tangun (nation)-Kim Ilseong(Socialist) nationalism.
