Although the Yuan Dynasty was defeated by the Ming Dynasty, its own strength was still strong during the Northern Yuan Dynasty (1368-1402). Goryeo, which had been a vassal state for a hundred years, oscillated left and right between the Ming Dynasty and the Northern Yuan. Subsequently, Lee Joseon (1392, 25 years of Hongwu) usurped the throne, still because of the Northern Yuan, lee Korea continued to oscillate around the Ming and Northern Yuan.
At the same time, Tsang-ra was eventually annexed by Silla, thus laying the political map of today's Korean Peninsula. However, when Goryeo Korea was established (unifying the Korean Peninsula in 936), Thanra refused to continue as a vassal state, and the two sides went to war, and two years later Thanhra succumbed. In the fourth year of the Northern Song Dynasty (1105), Goryeo Sujong turned the kingdom into a county and officially annexed Jeju Island.
In the relations between the Yuan Dynasty, Jeju Island was returned to China again in 1274, and Goryeo Korea existed as a vassal state.
The relationship between the Yuan Dynasty and The Tang Dynasty
In 1273, Goryeo formally submitted to the Mongol regime (the Southern Song Dynasty still existed, the ancestor of the Yuan Dynasty Kublai Khan to the 10th year of the Yuan Dynasty), and established the Tamra State Recruitment Division, with 1,700 troops on the border of Tunzhen. It has been subordinated to Zhongshu Province, Liaoyang Province, Zhengdong Province and other institutions.
In 1274, Tanluo officially became a direct territory of the Yuan Dynasty.
After 1294 (Kublai Khan on February 18), part of the jurisdiction was returned and the Yuan and Gao were jointly administered.
Six years later, it was brought under the direct control of the Yuan Dynasty. For another five years, part of it was returned to Goryeo. Repeatedly drifting between Goryeo and the Yuan Dynasty.
The reason why the Yuan Dynasty attached great importance to Tanluo was mainly for two reasons.
First, the geographical location of Tamra is very important. It is about 85 kilometers from the southernmost tip of the Korean Peninsula, across the sea from Japan's Tsushima Island and Nagasaki Prefecture to the east and Jiangsu and Zhejiang in China to the west.
The Yuan Dynasty controlled Tamra, that is, it had a maritime base to monitor the three places, and when the Yuan Dynasty conquered Japan, It was both a logistics base (weapons and military posture, warships - a hundred ships were built) and a starting point for the Eastern Expedition against Japan.
In 1273, he directly controlled Tamla, also in order to directly monitor the Southern Song Dynasty regime from the sea and land. After the collapse of the Southern Song Dynasty, it was also a place to guard against rebellion in the south.
Second, Tamla has produced warhorses since ancient times, which is a very suitable place for horse breeding in Asia, with abundant water and grass and suitable climate. As a nomadic people, the Mongols attached particular importance to war horses. To this end, Tamla served as a horse farm in Mongolia in the fourteenth year of the 14th century (1277).
The main goryeo ponies of Tamla are better endurance, and this horse is called "village horse"; the horse sent from Mongolia is called "Huma", but it is not many.
In addition to the above two reasons, the early Yuan Dynasty often sent people to Jeju Island (Tamra) to skillful naval warfare.
Throughout the Yuan Dynasty, Jeju Island was a place of exile for prisoners.
In April of the twelfth year of the Yuan Dynasty (1275), more than 100 people were exiled, 33 in May, and more than 40 people in August. After that, the exile of prisoners continued. Even the Imperial Family had people, such as The Wei King Amuge and others.
Emperor Yuanshun's plan to escape jeju island
In February of the 27th year of Zhizheng (1367), Emperor Yuanshun sent Gao Gaobei to Goryeo to meet with Wang Qi (王祺), the king of Gongju, and told him that the emperor was preparing to avoid chaos in Jeju, and in order to give back, Jeju Island was returned to Goryeo. At the same time, this time the reward for Wang Hao was extremely rich, with 550 horses of colored silk brocade, which had not been rewarded before or a few horses, dozens of horses. It can be seen that making good friends with Goryeo makes choices for avoiding chaotic destinations.
This historical material is from the History of Goryeo. It can be seen from this that some people absurdly unfold their talents and say that the Ming Dynasty let Emperor Yuan Shun escape. This historical data can prove that for escaping from Dadu, it was already the established policy of the Yuan Shun Emperor. However, the speed of the Ming army was indeed relatively fast, and Emperor Yuan Shun, who had not yet made up his mind where to flee, fled in an unexpected panic.
Similarly, in September 1369, Wang Hao transferred eleven craftsmen from Jeju Island to build a palace and asked them to work for themselves. Among them, Yuan Shi told Zaifu that the Emperor of the Yuan Dynasty had lost the world because the Emperor of the Yuan Dynasty was going to flee to Tangluo, so we craftsmen were sent. In less than two years, the world has changed greatly, and we are lucky to have come here because we were requisitioned.
Zhu Yuanzhang did not recover Goryeo, only to make good friends with Goryeo
After the fall of the Yuan Dynasty, the Mongol forces on Jeju Island were relatively strong. Because of the exiles, the warhorse bases, the people and horses who monitored the Japanese Goryeo regime in southeastern China, and the palace-building personnel sent by Emperor Shun, the Mongol forces (including the various ethnic groups, including the Han chinese, who were inclined to the Yuan Dynasty) were still fighting, and this was their last base.
Is it possible to escape back to Mongolia by land and sea? Nor is it possible to go north by land. Therefore, the metaphor of "trapped beasts and beasts fighting" can show its danger even more.
The Mongol forces on Jeju Island conspired with pro-Yuan forces in Goryeo to defeat the Goryeo army several times, and eventually staged a coup d'état to kill the Goryeo king Wang.
At first, Wang Asked Zhu Yuanzhang for permission to attack the Mongols on Jeju Island. In the third year of Hongwu, the pro-Yuan forces of the Qi clan were killed, and the prime minister Yin Shi was killed when he was sent to ask for guilt. Wang Zhao showed his loyalty to Zhu Yuanzhang and asked for approval. Zhu Yuanzhang refused, demanding that he treat the Inner Mongolians well.
However, after the defeat of Hongwu at the Battle of Lingbei in the fifth year (Wang Hao again requested permission to attack before he failed, and when the Battle of Lingbei was at war in July, Wang Hao's third request was rejected by Zhu Yuanzhang to ask him to treat the Mongols well), and Wang Hao, the king of Goryeo, fearing the strength of the Northern Yuan, eventually endangered Goryeo and began to re-make friends with the Mongols on Jeju Island.
In this case, Zhu Yuanzhang changed his previous attitude and began to personally hand-write wang hao to launch an attack on Jeju Island. Mainly to test Wang Zhao's attitude towards The Northern Yuan. The following year, in order to prevent the Ming Dynasty from being known, Wang Hao received the Northern Yuan emissaries in the middle of the night.
Zhu Yuanzhang was very angry about this, and coupled with the stimulation of the two killings of the envoys, Zhu Yuanzhang issued a military threat. Wang Hao had no way, thinking that he had offended The Northern Yuan before, and could only hold ming dynasty's thigh.
In the seventh year of Hongmu (1374), Goryeo Joseon conquered Jeju Island and sent the heads of three Mongol chiefs on Jeju Island to Nanjing.
Even so, Wang Was killed by pro-Yuan forces in 1375. Subsequently, lee's Joseon dynasty of Goryeo appeared, and Zhu Yuanzhang, facing the strategic location of Jeju Island, did not ask for the ownership of Jeju Island for the purpose of wooing North Korea.
However, this problem continues to this day, and Jeju Island is not there, which has a far-reaching impact on China. Although, because of the problem of national strength, the Korean regime became a vassal state in peace, but the question is, what if he becomes a vassal state of other great powers?
The three functions of Jeju's strategic position (looking at the Korean Peninsula, Southeast China, and Japan) will be activated, which will have a great impact on China's strategic interests.
