The policy of peace and pro-family, as a political activity between the Central Plains Dynasty and the surrounding regimes, for the Central Plains Dynasty could maintain stability in the border areas and strengthen its rule with a policy of gentleness; for the vassal regime, it could increase the political chips for the survival of the regime. Its appearance is also a long history, dating back to the Spring and Autumn Period and the Warring States Period. The lost affair between the Goryeo king Wang Fu and the Yuan Dynasty princess Kudu Lujian is also the product of a political union.
As the predecessor of the Yuan Dynasty, the Mongol Empire, under the leadership of Genghis Khan and Kublai Khan, gradually achieved unification, expanded its sphere of influence, and successively attacked the Western Liao, Western Xia, Jinguo and other countries, and the Goryeo Dynasty located on the Korean Peninsula naturally became their target.
During the reign of Emperor Yuanxianzong, he sent a large army to attack, hoping to destroy the Goryeo Dynasty in one fell swoop with the bravery and good warfare of the Mongol Iron Horse. Although the Goryeo Dynasty was weak, the suzerainty of the Song Dynasty was powerless, and the Mongol army also achieved the battle record of "pulling up the city out of ten", the people of Goryeo still relied on their own stubborn resistance, so that the Mongols' plan to destroy the country was broken. In the end, the Goryeo king Gojong Wang Hao had to decide to make his son Wang Jung a proton and submit to the Mongols. After Wang Hao's death, Kublai Khan released Wang Wei to Goryeo to inherit the throne as Emperor Wonjong of Goryeo.
In 1260, after Kublai Khan established the Yuan dynasty, Wang Qi went to worship as a vassal state. Although Kublai Khan promised to "complete the old frontier, the An Ertian domain, and the Paul family", but this is obviously not a guarantee of safety for the Goryeo Dynasty, if it can make peace with the Yuan Dynasty and seek a princess, the Goryeo Dynasty will certainly sit back and relax, and can also use the power of the princess to eliminate the power of the internal and consolidate its rule.
Therefore, Wang Qi wrote to Kublai Khan, hoping to marry a princess, but Kublai Khan, as the ruler of the entire Mongol Empire at that time, naturally did not have any comment on the weak Goryeo kingdom. However, Wang Qian was naturally unwilling, so he was willing to ask his son Wang Fu as a hostage and propose marriage again. Although Kublai Khan had already refused many times, he saw that Wang Kui was so sincere, and he agreed to lose his concubine Princess Kudu Lujian and marry Wang Qi's crown prince Wang Zhuo. Wang Qian was naturally satisfied, and naturally attached great importance to the arrival of his daughter-in-law. Not only did he order the harem concubines and the wives of the ministers to greet them, but he also personally brought a group of courtiers to wait on the shore. In the face of such a grand ceremony, Wang Xuan also demoted his concubine to Zhenhe Princess, and Kudu Lujian naturally became the rightful place when he was lost.
It is said that this princess is noble, and should have been knowledgeable and gentle, but Kudu Lujian was lost on the contrary, as a Mongol, and kublai Khan's concubine, she was spoiled and habitual from an early age. As soon as he married into Goryeo, he began to "be a demon", not only insulting the prime minister and other courtiers at every turn, but even his husband Wang Yu did not let go, and even beat him with a cane. At this time, although Wang Xuan became the king, but helplessly her mother's family was strong, but "the king could not forbid it, but just wept." A king, being beaten and crying is also rare.
What's more, at the wedding feast where Kudu Lujian lost the birth of his son Wang Yuan, in front of the Goryeo courtiers, Hou Zhen and the palace master knelt down to toast, while Wang Fu looked back at Kudu Lujian and lost a glance, but even after looking at you more in the crowd, Kudu Lujian was so angry that he not only ordered the banquet to be revoked, but also ordered someone to file a complaint to the Yuan Dynasty, fortunately, the great general Du'er felt that this was only a family affair between husband and wife, and did not have to be reported, so he suppressed this time, but Zhen and the palace master were also beaten into the cold palace, and Wang Xuan was ordered to never communicate.
It is said that marrying a wife and marrying a sage, this Wang Meng naturally has a thousand unhappiness in his heart, fortunately, this princess does not live long, in 1297, at the age of 38, she died, but even so, The King of Goryeo wang Fu was also concerned in his heart, afraid of being pursued by the Yuan Dynasty, and had to pass the throne to his son.
