12세기 초 국제 정세와 麗金 간의 전쟁과 외교

Abstract

In the late nineteenth century, Jurchens (女眞) widely extended its influence. From the time of Jin’s establishment up to the collapse of Northern Song (北宋), the relationship between Goryeo (高麗) and Jin (金) can be classified into the following. Before the Jurchens established Jin, the herandian war occurred between Goryeo and Jurchens. In the beginning, Goryeo won the war by mobilizing more than 170,000 forces and constructed nine fortresses in the war zone. Goryeo then received an agreement in which Jurchens would not invade Goryeo (高麗) further and returned nine fortresses in the war zone. When Jin and Liao started the war which brought the fall of Liao,Goryeo monitored the situation closely and refused to enter the war on the Allied side. Finally, Goryeo cancelled subservience to the Liao and endeavored to regain Koguryo’s former territory through diplomatic efforts. At the end, Goryeo occupied both Baozhou and Laiyuan forts. Goryeo tried to advise Northern Song for the near future when Northern Song concluded a new pact with Jin. However, Beisong concluded a new pact with Jin and Liao was destroyed. Before Liao was destroyed, Goryeo played a leading role to ward Jin,and Jin maintained taking a passive stance toward Goryeo. However, Goryeo maintained the same subservient way to Jin as Goryeo did to Liao and obtained Baozhou fort from Jin(金). Song(宋) tried to exploit Goryeo, which was under the control of Jin,but Goryeo acted on its own. Goryeo strenuously handled the issue of regaining Koguryo’s former territory and took practical interest. From 1127, Goryeo and Jin maintained amicable relations with each other. The reason why Goryeo and Jin maintained good relations with each other is that Jin and Southern Song often made regional wars, while Northern Song and Liao had no war after concluding the new pact. Secondly, Goryeo concentrated its diplomatic efforts against rapidly changing circumstances.
