In April 1259, Gojong's eldest son, Gojong of Goryeo, entered the Mongol dynasty on behalf of his father.
At that time, Möngke Khan was launching an attack on Hezhou in the Southern Song Dynasty, and the prince was ordered to go to Sichuan to meet Möngke Khan. However, in July of the same year, during his campaign against the Southern Song Dynasty, Möngke Khan died of illness in the Diaoyu City of Hezhou (present-day Chongqing) in Sichuan.
Upon learning of Möngke Khan's death, the prince of Goryeo made a decision that surprised many: instead of returning to China immediately, he turned to meet Kublai Khan of Mongolia.
This decision is of great significance to the relationship between the two parties. The prince greeted Kublai Khan at Bianliang, which made Kublai Khan very happy. He thought it was "providence" and praised him greatly.
He also saw the determination of the prince and decided to adopt a policy of gentleness, which made the relations between Mongolia and Goryeo develop in a good direction. Soon after, news of Gojong's death in Goryeo reached Kaipyeong.
In order to win the hearts of the princes, Kublai Khan decided to improve the treatment of his pavilion and made him the new king of Goryeo. This decision not only did not move the war, but also allowed Goryeo to be annexed to the Mongols, reflecting the intention of the Central Plains Dynasty to establish good-neighborly and friendly relations with neighboring countries.
After returning to China, he became the king of Goryeo, and his appearance marked the improvement of relations between Mongolia and Goryeo, and also laid the foundation for further cooperation between the two sides.
After returning to Goryeo, he went to Kaesong with Shuri Daeson to inspect the construction of the old capital. When Kublai Khan heard that his son was staying in Goryeo Xijing, he sent people to urge Yuanzong to succeed to the throne, and in April, Yuanzong succeeded to the throne on Ganghwa Island.
After Wonjong of Goryeo ascended the throne, he changed his attitude towards resisting Mongolia during the Gojong period, and the two countries had frequent exchanges. Kublai Khan adopted a liberal attitude towards shaving his hair in accordance with Mongolian customs, and no longer forced the Goryeo king to pro-dynasty and shave his hair.
After Kublai Khan ascended the throne, he issued an edict to Goryeo to succeed to the throne of the new Khan, with a generous attitude, and asked Yuanzong to persuade the farmers to teach the farmers and the remnants of the people, believing that it was a good thing for the people to live in peace when Goryeo went out of the water and land.
In June of the same year, Yuanzong sent his son Yongan Gongxi to Mongolia to congratulate Kublai Khan on his accession to the throne, and Kublai Khan asked Yongan Gongfu to return to Goryeo with three edicts, one of which said that Mongolia would withdraw its troops in the autumn, and the attached Goryeo people were not required to shave their hair and wear Hu clothes.
Another edict told Goryeo to send the king's seal, tiger talisman, clothes, swords, bows, etc. After Goryeo was canonized by the Mongols, in addition to regular tribute, the affairs of the DPRK and China were also interfered by the Mongols, and the affairs of the DPRK and China were also interfered with, and the affairs of the DPRK and China had to be reported to the Mongols.
In 1260, the king of Goryeo changed his name to Yu and sent his son to pay tribute to Mongolia, which was also renamed Yu. Subsequently, the prince returned to Goryeo. However, Goryeo was often harassed by the Jurchens when sending envoys to Mongolia.
After Kublai Khan quelled Ali Buge's rebellion, he sent an envoy to ask Yuanzong to go to Mongolia in person, and asked Yuanzong to gather the princes and nobles in Shangdu to celebrate the victory, and let Yuanzong also participate.
The Goryeo courtiers were divided on the issue, and most of the ministers were skeptical of the Mongols. However, Li Zangyong believed that Yuanzong's pro-dynasty was conducive to the friendship of relations between the two countries, and Yuanzong adopted his opinion.
In June of the same year, Yuanzong arrived in Mongolia with Li Zangyong and met Kublai Khan in Shangdu. Yuanzong's visit was treated well by the Mongol princes, which further promoted the improvement of relations between the two countries.
However, when Kublai Khan demanded that Goryeo fulfill his demands for conscription, food assistance, household registration, and tuntian, Yi Zangyong explained to Mongolia the difficulties in Goryeo and politely rejected the Mongol request.
Wonjong agreed with Kublai Khan that the Mongols would withdraw their troops from Goryeo, and Goryeo moved out of Ganghwa Island for three years. Although relations between the two countries improved after Wonjong's pro-dynasty approach, the Goryeo courtiers still had differences of opinion on Wonjong's pro-dynasty issue.
However, Li Zangyong believed that Yuanzong's pro-dynasty friendship was of great significance to the friendship between the two countries, so Yuanzong finally decided to go to Mongolia in person.
Original text: The main task of staying in Tokyo should be to urge Goryeo to move the capital. When Park Cheon-sik returned to Goryeo in September 1259, he also sent a large number of people to Goryeo to inspect the situation in the water and land dwellings.
When Li Shicai was in Mongolia, Hong Chaqiu, the son of Hong Fuyuan, said to Kublai Khan: "The surrender of Goryeo is not true. So in November, Li Shicai came to review the situation of preparing to go to land.
At this time, the son of the Emperor was in charge of the government in Goryeo, and out of helplessness, he had to send troops to start building a palace in the old capital of Kaesong. In the first month of 1260, Goryeo was born.
Kublai Khan accused Goryeo of failing to fulfill its six obligations after annexing Mongolia, including sending troops, helping in war, and sending food, and said that Goryeo's move out of Ganghwa Island was a sign of his sincere attachment to Mongolia.
Kublai Khan was anxious for Goryeo to move out of Ganghwa Island in order to better fulfill these obligations. In addition, the attitude towards Mongolia within Goryeo and the disagreement over the relocation of the capital faltered the plan.
Lin Yan and others opposed the relocation of the capital, and tried to abolish Yuanzong and make his younger brother king. However, Lin Yan sent Guo Rubi to Mongolia with the letters of Yuanzong and the new king, and reported to Kublai Khan in the name of Yuanzong.
On his way back to Goryeo from Mongolia, he learned of this and returned to Mongolia to report to Kublai Khan. Kublai Khan sent Si Duo Si Buhua and Li Ge to Goryeo for more information, and expressed surprise at the abolition of Wonjong by the ministers.
The Mongol court believed that Yuanzong was not at fault, and even if there was, it should be up to them to decide, and it was not permissible to depose the king without permission. In addition, the Mongol court warned Lin Yan and others not to harm Yuanzong's father and son, and they must explain in detail the reasons for deposing the king.
Kublai Khan sent 3,000 troops led by the prince to return to Goryeo to relieve the country. At the same time, the Mongol court was discussing the matter of conquest of Goryeo, and some people advocated taking the opportunity to send troops in the name of Japan, but others believed that it was not appropriate to send troops at this time, and that they should wait for the Goryeo side to express their feelings before considering it.
At the same time as the deposition of Wonjong, Choi Tan and others led the troops of Goryeo to annex the Mongols, which brought the following 60 cities of Goryeo Xijing under the jurisdiction of the Mongols. If Lin Yan and others did not re-establish Wonjong as king, Mongolia would interfere in the internal affairs of Goryeo by force.
In desperation, Lin Yan and others re-established Yuanzong as king in November, and let his son Shun'an Hou Yi Jian Guo, personally enter the Mongolian court. In 1270, Wonjong of Goryeo went to Mongolia, but the Mongols allowed only 400 members of his retinue to meet him.
The Mongol court considered Lin Yan and Shu's actions to be a rebellion against the Mongols, but Lin Yan's sins were unforgivable, and he could be forgiven because he was at the mercy of the authorized ministers.
According to the "History of the Yuan Dynasty", in February of the seventh year of the Yuan Dynasty, the king of Goryeo, Wang Yu, came to meet the court and received an edict, requiring the king's head and brother to lead the army into the old capital of Goryeo, and to escort him back to China with Toduoer and Jiao Tianyi as the king Daru Huachi.
At the same time, Yuanzong issued an edict: "Lin Yan is abolished, and the crime is unforgivable." Anqing Gongshu has to be forgiven. There are those who can carry out the send-off, even if they are still in the party, they will also regain their official rank. ”
Soon after, Lin Yan died of depression. In June of the same year, Motomune and Sekotsu left Mongolia and arrived in Tokyo in February. In May, the Yuan sect sent Zheng Zixi and Li Fenxi back to Goryeo to inform the countrymen of Kublai Khan's orders.
However, Lin Yan's son Lin Weimao refused to carry out the order, which caused Song Songli, Hong Wenxi, and others from the Qiandu faction to kill Lin Weimao. After this incident, the Goryeo warrior regime finally came to an end, and the power of the vassals who had obstructed the relocation of the capital collapsed.
On the one hand, it is related to the fact that Yuanzong was deposed by Lin Yan and reinstated by the intervention of the Mongols, and on the other hand, Yuanzong may have realized that it was a matter of time before the Mongols destroyed the Southern Song Dynasty.
Therefore, judging from the political trend at that time, Yuanzong needed to rely on the protection of Mongolia to prevent the recurrence of the incident of the powerful ministers arbitrarily controlling the government. Therefore, he moved out of Ganghwa Island in accordance with the Mongol wishes and returned to the old capital of Kaesong.
In Kublai Khan's time, the Mongol aspirations, which had not been fulfilled after several generations of Khan and decades of conquest, were now realized without the use of force. In the same year, the Mongols changed the name of Goryeo's Xijing to Dongnyeong, appointed Chotan as the governor, and sent Daru Huachi to oversee it.
The Mongols established Dongnyeong Province in Goryeo, which governed 54 castles including Seogyong and 6 castles in Sehaedo. In fact, all 60 cities were occupied by the Yuan, thus reducing the territorial extent of Goryeo.
Therefore, the existence of Dongnyeong Province and the Shuangcheng Governor's Office in the northeast region caused Goryeo to lose its outposts in the north on both the east and west, and at the same time, it was unable to get rid of the complete suppression of Yuan.
Against this backdrop, the garrison of Hwasa Island in Goryeo opposed the relocation of the capital, triggering a rebellion. Sambetsu was a special unit in the Goryeo period, similar to the Imperial Forest Army, consisting of the Left Betsu, the Right Betsu, and the Shinyi Army.
In May 1270, after Yuanzong moved back to the old capital, he sent Jin Zhidi to Ganghwa Island to disband Sanbetsu Copy, which caused a rebellion against Sambetsu and Lin Yanyu Party Pei Zhongsun led the Sambetsu rebellion.
In June, Pei Zhongsun and others supported Yongning Gongjiao's eldest brother Chenghua Hou Wen as king and established a pseudo-**.
Pei Zhongsun led his army south, occupied Zhendao as a base area, and continued to invade the surrounding prefectures and counties. At the same time that Goryeo sent Kim Fangqing to crusade against the rebels, he also sent people to report the rebellion to Mongolia, and Mongolia sent troops to join forces with Goryeo.
Yuan Zong sent Shen Si Ji to Jeolla Province to defeat the rebels, Shen Si Ji fled back to the capital after learning that the rebels had landed, and the Mongolian commander of the Tuntian Army in Kaegyung, Ah Hai and Goryeo Kim Fang Kyung, led troops to pursue the rebels, but Ah Hai led too many troops and did not achieve victory.
So Kublai Khan deposed Ah Hai and ordered Hong Chaqiu to lead the Goryeo army to march to Jindo. Kublai Khan ordered Kudu Da'er to hold an edict to the Goryeo Lim Yan remnants, but the rebels wanted to get Jeolla Province and then subordinate it to the Mongols.
The Mongols did not agree, but the edict to the rebels was unsuccessful. Hong Chaqiu asked to attack Zhendao with Hu Linchi and Wang Guochang, and Kublai Khan agreed and ordered Xi and Yong to lead the Goryeo army from Liaodong to conquer together.
Goryeo Yuanzong ordered Kim Fangqing and Mongol Marshal Xindu to fight against the rebels in Jindo, and finally broke through Jindo in May, captured more than 10,000 men and women, killed the puppet king Chenghua Hou Wen, Bae Zhongsun was killed in battle, and Kim Tongjing led the remnants of the force to flee to Tamna Island in southern Goryeo.
In March 1272, Goryeo sent an envoy to the rebels based on Jeju Island, but Kim Tong-jeong refused to surrender and continued to loot food in Jeolla-do and other places. In December, Hong Chaqiu went to Mongolia to ask Kublai Khan to make a decision, and Kublai Khan ordered Hong Chaqiu to be the marshal of the Goryeo Army and go to Jeju Island with Xindu to defeat the rebels.
From March 1272 to the first month of 1273, the rebels invaded Huining County, Dapu and other places to loot supplies, and in February 1273, Jin Fangqing, the marshal of the Chinese army's marching battalion, led 800 elite cavalry to attack the rebels in Tamna.
Kublai Khan responded to Yuanzong's request to reduce the Hongchaqiu tribe to pacify the three beyond. In April, the Mongol-Goryeo coalition army broke through the city of Jeju, Kim Tongjing fled to his death, and Sambetsu surrendered.
After the rebellion was quelled, the Mongols set up a recruitment division and a border army on Tamna Island, and there was no more war between the two countries.
