Abstract

After the death of King Daeso of Dongbuyeo(東夫餘), Buyeo of the Nak’s Kingdom, which was initially sealed by Goguryeo(高句麗) as Buyeo King, is not a lord belonging to the Goguryeo Yeonnabu(椽那部). It can be confirmed through Korean-Chinese historical records that it was a royal state with independent military, diplomatic, and trade rights. King Daeso's younger cousin, who surrendered to Goguryeo, was not a heir to the throne, so he was not eligible to surrender by sacrificing his country, so it can be seen as an exile with his followers. Goguryeo, which wanted to become a new hegemonic power, established a new Buyeo as a result of King Daemusin's strategic proposal to expand its power by turning the royal family of Dongbuyeo into a reliable ally. The relationship with Goguryeo can be seen as a bandwagon alliance if analyzed by modern international political relations theory (IR). Buyeo became a target of the enemy and suffered serious damage when it participated in Goguryeo's hegemonic war, and Goguryeo's discriminatory support for this became the background for Buyeo to break its alliance with Goguryeo and collude with Houhan(後漢). King Uigutae(尉仇台), who rejuvenated Buyeo, secured the Daebang(帶方) area with Gonsongang(公孫康), the son of Gongsondo(公孫 度), the Taishou of Liaodong(遼東太守), and move the capital. For this Buyeo, which was in the Liaoseo(遼西) area from the 1st to the early 4th centuries, I suggest that it is necessary to classify it as 'Seobuyeo(西夫餘)' for the systematic organization of Buyeo history research.
