The purpose of this paper is to reveal how the academic tendency of trying to understand one’s national history from the ‘internal’ perspective-a perspective that which defines one’s national history as a result of their own independent choices-was begotten in each country according to their own particular historical situation, as it did in the case of Korea. The study of Korean history has been conducted in ways that differ from one time period to another, accordingly to the context of each time period. Interestingly, the new trend of studying Korean history from the perspective of independent or internal development came from North Korea, where the concept of historicity is essential to the building of its socialist government and society. Also, Korean ­Japanese researchers of the Korean descent acted as the mediator of intellectual exchange, despite suffering from discrimination by the Japanese. In South Korea, it was Kim Yong­Sup who first adopted the perspective with his research, which was focused on trying to explain the relationship between war and society. This study is also an effort to find the point of intersection between the academic tendencies in Korean history and Northeast Asia history, the point which also provides to be a turning point for Korea. This new trend of studying Korean history was adopted by the academia of Northeast Asian history at relatively same time period. Since then, with the help of direct or indirect exchanges, academic researches of the trend have accumulated in Northeast Asia. Finally, by 1950’s, the new perspective, or the positive mindset that we can overcome the discourse of the Orient as a particular, was born.
