The study of Khitan-Liao history in Korea has been in existence since the 1950s. However, the number of researchers is not even ten in the history of research that has been going on for 70 years. Few researchers have developed the research on the Khitan-Liao history of Korean academia and have made effort to form a basic foundation for research. In this article, I analyzed the research trends of Khitan-Liao history in Korean academia and found that researchers achieved certain results in terms of political history, social history, and institutional history. Based on this, further and more detailed researches should be conducted.
But, when compared with the movement of overseas academic community toward the development of the study of Khitan-Liao history, there are many deficiencies in Korean academic achievements. In addition, until the 1990s, related research was actively coming out, but in the 21st century, it is unlikely that the activity is the same as before. The lack of resource and the question of the reliability of Liao History(『遼史』) were one of the reasons why researchers did not show interest in this period. However, the demand of researchers who want to understand the history of Khitan-Liao is very large, and the fact that it operated the dual system for the first time is the value of the research.
The development of research has been continuing, including the discovery of new resources, the advancement of archaeological achievements, and the development of research on deciphering Khitan scripts. Now it can be said that the field of ‘Khitan Studies’, which is not limited only to the study of history, is increasingly being formed. The historical significance of Khitan-Liao as the so-called ‘the first conquest dynasty’ is very important, and there are still many challenges that need to be clarified to explain it. In the future, I hope that the Korean scholarship will be actively pursued for the development of ‘Khitan Studies’, including the history of Khitan-Liao.
