Although the founding emperor of the Tang Dynasty was Li Yuan, the emperor of the Tang Dynasty, half of the Tang Dynasty was basically beaten down by his talented second son Li Shimin, who became emperor and became the emperor of Tang Taizong. Tang Taizong never worried about the heir issue, because he had 14 sons, but most of these 14 sons did not end well, three were killed, three committed suicide, three died early, and one was claustrophobic. Among them, the third son who was killed, Li Ke, was the son that Tang Taizong most admired, because this son was the most like Li Shimin. At one point, Emperor Taizong of Tang even wanted to make his third son, Li Ke, crown prince. However, Emperor Taizong of Tang eventually made Li Zhi, the son of Empress Changsun, crown prince. Li Ke was executed by Emperor Gaozong's chancellor for plotting a rebellion, and Li Shimin would shed tears under the Nine Springs.
The person who dared to frame the crown prince was naturally not an ordinary person, he was the eldest grandson of Emperor Taizong of Tang's li shimin. If you want to say what Li Ke's greatest sin is, it is that he has cast a wrong fetus, and his mother is the daughter of the Sui Emperor. Everyone knows that the change of Xuanwu Gate opened the curse of the Tang Dynasty prince. Emperor Taizong of Tang's first crown prince was his eldest son Li Chengqian, whose crown princeship was coveted by his fourth brother Li Tai, and the two fought for each other. Li Chengqian actually sent someone to assassinate Li Tai, and after the matter was revealed, Li Chengqian did not stop forcing the palace, hoping to make another change in Xuanwumen and make Tang Taizong abdicate. Emperor Taizong of Tang was furious and deposed Li Chengqian as crown prince, and Li Tai was involved in a power struggle, and naturally did not fall into Tang Taizong's eyes. With the support of the powerful forces of Changsun Wuji and Empress Changsun, Emperor Taizong of Tang eventually made his ninth son Li Zhi crown prince.
However, Li Zhi was too cowardly, and Tang Taizong wanted to replace the crown prince with his third son Li Ke, and summoned the eldest son Wuji to discuss the matter, and the eldest son Wujie resolutely disagreed with the change of the prince, after all, Li Zhi was his nephew. In the end, the eldest son Wuji forced Tang Taizong to give up the idea of changing the crown prince, but the hatred for Li Ke in his heart was indelible. After the death of Emperor Taizong of Tang, Li Zhi smoothly became Emperor Gaozong of Tang. As the king of the domain, Li Ke did not have the idea of being an emperor, scrupulously fulfilled his duties, and managed his territory in an orderly manner, and Emperor Gaozong of Tang repeatedly sealed this brother.
However, the eldest grandson's hatred for Li Ke was growing day by day. In 653, Fang Xuan'ai's second son Fang Yi'ai and his wife Princess Gaoyang joined forces with Chai Shaowu and others to launch a coup d'état to depose Emperor Gaozong of Tang and install Li Yuanjing, the sixth son of Emperor Gaozu of Tang, as emperor. After the matter was revealed, all the people involved in the case were arrested, and the eldest grandson Wuji was responsible for hearing the case. Li Ke had nothing to do with this case at all, but the eldest grandson was unscrupulous and put a rebellious hat on him. Emperor Gaozong of Tang was merciful and wanted to pardon his brother, but was opposed by his courtiers. Eventually, at the age of 34, Li Ke was executed in Chang'an. Tang Taizong's favorite son was unjustly killed in this way. The eldest grandson Wuji did not have any good retribution, and was eventually forced to die by Wu Zetian.
