In China, female emperors are rare things, perhaps for ethnic minorities or foreigners it seems that it is not so strict, there are no sons, and it seems to work to use daughters to inherit the throne, unlike Wu Zetian, who has exhausted all means to become an emperor, and has waited for many years, but the disadvantage of using the heroine is that women must marry after all, and children also have sex with their husbands.
Therefore, the female emperor married a foreigner, and the regime was easily bypassed, and Vietnam has such a history. Speaking of Vietnam, they can't talk about their origins with our country. Everyone knows that Vietnam was once a territory of China, and even many Vietnamese people are just different in nationality, but they are all descendants of Chinese, and even their surnames are no different.
Around 1220, the reigning monarch of Vietnam was still the Lee dynasty, which was also the time when the Lee dynasty was about to be replaced, but this time the Chen clan replaced the Lee clan to take over Vietnam not through violent riots or what we think of as peasant revolts, but through marriage relations gradually replaced the Lee dynasty by the Chen clan.
Li Huizong, the last emperor of the Li clan, had no sons and left only a 7-year-old daughter, Li Zhaohuang (real name Li Tianxin), to inherit the throne. It is said that Li Huizong met a boy who was only one year older than his daughter, this boy was called Chen Rixuan, the second son of the taiwei Chen Cheng, who had the appearance of an emperor, and Li Huizong thought that because he was a female emperor, the throne would not last long, so he wanted to match her with a king.
Later, this boy named Chen Riyan really took Li Zhaozong's daughter Li Zhaohuang, and the Chen family had the opportunity to usurp the throne. According to the "Complete History of Dayue", Chen Rizong's ancestors came from China (there are two theories, one is from Quanzhou, Fujian, and the other is from Guangxi, but Quanzhou is more likely), and later became a fisherman in Vietnam, and there was some power, and then caught up with Li Gaozong and his son Li Huizong who fled due to the rebellion of Fan You, Li Huizong married Chen Rixuan's aunt on the way, and Chen turned salted fish into an imperial relative.
Chen Rixuan was supported by his uncle, who had also raised an army against Li Huizong's mother, and thus gained power, and li Huizong's administrative affairs also fell into the hands of Chen Siqing, and Chen Riqing's father Chen Cheng became a lieutenant after Chen Siqing's death. Another from the uncle Chen Shoudu was also appointed as the commander of the palace, and this background was not possible for the female emperor's husband.
Speaking of Chen Riyan's ability to "accept the Zen throne" is mostly due to Chen Shoudu, Li Zhaohuang was very fond of Chen Ridu, seeing this Chen Shoudu launched a coup d'état to force Li Zhaohuang to abdicate the throne, so the 8-year-old Chen Riyan became the emperor of Vietnam, and established the Chen Dynasty to replace the Li Dynasty, which is recorded in the "Complete History of Dayue History", of course, there are other statements, such as the "Yue Shiluo" said that the Chen clan was indeed allowed by Zen. But this kind of thing, everyone knows it.
Empress Li Zhao's fate was a bit tragic, not only was the throne taken away, but the empress's position was not preserved. However, it is still time to return to the protagonist Chen Rixuan, who made achievements in accounting, taxation, flood control, education, law, official system, and military system during his reign, and the relationship with the Song Dynasty had to be mentioned in diplomatic relations.
But in fact, one of the most surprising things about Chen Riyan is not how he changed from an ordinary Chinese to a foreign emperor, but the custom of inheriting the Vietnamese emperor from him, which is really the first, the so-called one mountain does not tolerate two tigers, but Vietnam often has two emperors in power since then.
It turned out that Chen Riyan Yuanfeng was eight years old, that is, when he was about 40 years old, he chose to take a back seat and let the crown prince Chen Huang succeed to the throne, but Chen Rixuan, who was supposed to become the Emperor taishang and did not care about political affairs, was actually still the head of a country, just presiding over the overall situation with his son, and this habit was already going to be nagged to death in China. But the strange thing is that in Vietnam it has persisted for generations, which is not surprising.
The 13th century was a time when the Central Plains was extremely turbulent, when the Mongol Empire was rising, the Mongols invaded the Song Dynasty and the Dali State in the south in the middle of the 13th century, and had the momentum of annexing the whole of Asia, Vietnam was so close to southern China, naturally it naturally became the target of the Mongols, Chen Riyan's dynasty and Mongolian soldiers inevitably had a war.
Chen Riyan personally supervised the army and supervised the battle, but at first he was also repeatedly frustrated, some people in the country already felt that they could not defeat the Mongols, and hoped to ask for help from the Song Dynasty, but the Song Dynasty was also in danger, but the attitude of the Taishi Chen Shoudu gave Chen Riyan the intention of fighting mongolia again, and actually fought the strong Mongolian troops, making the Mongols withdraw from Dayue.
Of course, later the form of Mongol rule in the Central Plains was irreversible, and Chen Riyan followed the trend and then submitted to the Mongols, but who remembers that this small country once defeated Kublai Khan's army as many as three times, which is really a miracle enough!
