The Korean–Jurchen border conflicts were a series of conflicts from the 10th century to the 17th century between the Korean states of Goryeo and Joseon and the Jurchen people.
In 993, the land between the border of Liao and Goryeo was occupied by troublesome Jurchen tribes, but the Goryeo diplomat Sŏ Hŭi was able to negotiate with Liao and obtain that land up to the Yalu River, citing that in the past it belonged to Goguryeo, the predecessor to Goryeo.[2][3]
Both Balhae remnants and miscellaneous tribal peoples like Jurchens lived in the area between the Yalu and Daedong rivers which was targeted for annexation by Goryeo.[4]
The Jurchens in the Yalu River region were tributaries of Goryeo since the reign of Wang Kŏn, who called upon them during the wars of the Later Three Kingdoms period, but the Jurchens switched allegiance between Liao and Goryeo multiple times, taking advantage of the tension between the two nations; posing a potential threat to Goryeo's border security, the Jurchens offered tribute to the Goryeo court, expecting lavish gifts in return, which was the custom of the sinospheric order at the time.[5]
The Joseon Koreans tried to deal with the Jurchens by using both forceful means and incentives. Sometimes the military was dispatched, in tandem with appeasement with titles and degrees, and allowing Jurchens to sell furs for Joseon crops to make up for Jurchens' lack of food. Starting with Lee Ji-ran's recommendation and example, attempts were started to acculturate Jurchens by having Koreans marry them to integrate them into Korea. Despite the tributary relations and gifting and acculturating, many Jurchen tribes were submissive one year and rebellious the next.[6][7] By the 1400s, the Ming Yongle Emperor was determined to wrest the Jurchens out of Korean influence and have China dominate them instead.[8][9]
A key Jurchen leader named Mengtemu (Möngke Temür), chief of the Odoli Jurchens, who had always claimed he had been a servant of the Taejo of Joseon since Taejo's days as a border general of Goryeo, and even following him (Taejo Lee Seong-gye) to his wars, because he fed Mengtemu's family and provided land for him to live during his impoverished youth. Mengtemu was asked by Joseon to reject Ming's overtures, but was unsuccessful since Mengtemu folded and submitted to the Ming in 1412.[10][11][12][13]
Joseon under Sejong the Great engaged in military campaigns against the Jurchen and after defeating the Odoli, Maolian and Udige clans, Joseon managed to take control of Hamgyong. This shaped the modern borders of Korea around 1450, when several border forts were established in the region.[14]
Nurhaci, who was originally a vassalage to the Ming dynasty,[15] made efforts to unify the Jurchen tribes including the Jianzhou, Haixi and Wild Jurchens.[16] He offered the Ming dynasty to send Jianzhou Jurchen troops into Korea to fight against the Japanese forces during the Japanese invasions of Korea in the 1590s. The Ming dynasty was still fully recognized by Nurhaci as his overlord since he did not send this message to Joseon and only to the Ming. Nurhaci's offer to fight against the Japanese was denied due to misgivings from the Koreans,[17] but the Ming awarded Nurhaci the title of dragon-tiger general (龍虎將軍) along with another Jurchen leader.[18]
Nurhaci later established the Later Jin dynasty and openly renounced Ming overlordship with the Seven Grievances in 1618.[19] A 30,000-strong Jurchen force led by Nurhaci's nephew Amin overran Joseon's defenses during the Later Jin invasion of Joseon in 1627. The Jurchens pushed Joseon to adopt "brotherly relations" with the Later Jin through a treaty. In 1636, Nurhaci's son and Qing emperor Hong Taiji dispatched a punitive expedition to Joseon because Injo of Joseon persisted in his anti-Jurchen (anti-Manchu) policies. Having been defeated, Joseon was compelled to sever ties with the Ming and instead recognized the Qing as suzerain according to the imperial Chinese tributary system.[20]
^Yun 1998, p.64: "By the end of the negotiation, Sô Hûi had ... ostensibly for the purpose of securing safe diplomatic passage, obtained an explicit Khitan consent to incorporate the land between the Ch’ôngch’ôn and Amnok Rivers into Koryô territory."
^Breuker 2010, pp. 220-221. "The Jurchen settlements in the Amnok River region had been tributaries of Koryŏ since the establishment of the dynasty, when T'aejo Wang Kŏn heavily relied on a large segment of Jurchen cavalry to defeat the armies of Later Paekche. The position and status of these Jurchen is hard to determine using the framework of the Koryŏ and Liao states as reference, since the Jurchen leaders generally took care to steer a middle course between Koryŏ and Liao, changing sides or absconding whenever that was deemed the best course. As mentioned above, Koryŏ and Liao competed quite fiercely to obtain the allegiance of the Jurchen settlers who in the absence of large armies effectively controlled much of the frontier area outside the Koryŏ and Liao fortifications. These Jurchen communities were expert in handling the tension between Liao and Koryŏ, playing out divide-and-rule policies backed up by threats of border violence. It seems that the relationship between the semi-nomadic Jurchen and their peninsular neighbours bore much resemblance to the relationship between Chinese states and their nomad neighbours, as described by Thomas Barfield."
