History of Goguryeo

First of all, from the perspective of the composition of the people, Goguryeo is a multi-ethnic country. In this regard, there is a significant difference from Silla and Baekje, which are both "Three Kingdoms". The main body of Goguryeo is the Goguryeo people of the Urugu family. In addition, the Mohe people also account for a large proportion. (Among the "Nine Oath Buildings" of the Central Army that unified Silla, this can be seen from three Goguryeo buildings and one Mohe people building.) When Goguryeo fell, Silla only absorbed a small part of the Goguryeo people, and the Tang Dynasty absorbed a small part. The other Goguryeo people should eventually be absorbed by the "Bahae Kingdom". Only a small part of the territory of the Bohai Kingdom is on the Korean Peninsula. Moreover, the Liao Dynasty destroyed the Bohai Sea, the Jin Dynasty destroyed the Liao Dynasty, the Yuan Dynasty destroyed the Jin Dynasty, and the Ming Dynasty destroyed the Yuan Dynasty. As minority regimes, the Liao, Jin, and Yuan Dynasties all considered themselves orthodox in China, so the Bohai Kingdom The country is the history of China. Most of the Goguryeo people became Balhae people, so it should be said that most of the Goguryeo people were absorbed by the current Chinese people. Therefore, from the perspective of the ownership of the Goguryeo people, it is more appropriate that the history of Goguryeo belongs to Chinese history.

Secondly, from the perspective of the focus of national policies, before Pyongyang moved its capital, Goguryeo’s policy focus was toward the west and south, because the political and military opponent in Goguryeo’s mind was China’s power. , was also somewhat ambitious towards the Central Plains, so the history of Goguryeo during this period should be the history of China; after Pyongyang moved its capital, Goguryeo’s westward and southward expansion was blocked by the powerful forces of the Central Plains, so the focus of Goguryeo’s policy shifted to the Korean Peninsula. This period is the real "Korean Three Kingdoms Period", and the history of Goguryeo at this time should belong to the history of Korea.

So, traditionally, there is no problem that the history of Goguryeo (especially the later period) belongs to Korean history, no matter from the Chinese perspective of "what happened on the current land of the country is the history of the country", Judging from the conventions of the international historical community, it should be recognized. At the same time, the history of Goguryeo still belongs to Chinese history, because its origin is in the current territory of China, and the main scope of activities in the early and middle periods is also generally in the territory of present China.

In short, I think the traditional "one history for two purposes" in Chinese historical circles is more in line with the understanding of the history of Goguryeo. I oppose the Northeast Engineering Project’s view that “the history of Goguryeo belongs only to Chinese history” and the Korean academic circle’s view that “the history of Goguryeo only belongs to Korean history.”
