The Tang Dynasty began by deposing the Crown Prince

In the Tang Dynasty, the crown princes who succeeded to the throne were Li Yu, Li Heng, Li Longji, Li Longji, and Li Shimin.

In the Tang Dynasty, there were two crown princes who successfully succeeded to the throne. The first was Li Yu, the crown prince of Li Heng, who succeeded the throne and became Emperor Shunzong of Tang. The second was Li Ke, the crown prince of Emperor Gaozong of the Tang Dynasty. He succeeded the throne and became Emperor Xuanzong of the Tang Dynasty.

The Crown Prince of the Tang Dynasty, Li Chengze, was the second prince born of the Qing Emperor and Noble Consort Shu. He was a character in the TV series " Celebrating Years ", played by Liu Duanduan.

There were many reasons why the Tang Dynasty Crown Prince Li Chengqian was deposed. First of all, Li Chengqian's character was corrupt and he lost the trust and respect of his father and his subjects. He did not obey his father's orders, did not respect his teachers, did not care about political affairs, indulged in wine, sex, and pleasure, wasting the country's financial and material resources. He had also befriended some crafty people and listened to their instigation, betraying his father and country. Secondly, Li Chengqian's rebellion violated his father's bottom line and endangered the country's security and stability. He attempted to assassinate his brothers and ministers, and even wanted to overthrow his father's rule and seize the throne. Such behavior forced Li Shimin to depose him as the Crown Prince and exile him to other places. In general, Li Chengqian's misbehavior and rebellion were the main reasons for his dethronement.

The Crown Prince of the Tang Dynasty, Li Chengze, was the second prince born of the Qing Emperor and Noble Consort Shu.

In the end, Li Chengqian, the crown prince of the Tang Dynasty, was demoted to a commoner and exiled to Qianzhou. Because of his rebellion, he was deposed as a commoner by Li Shimin and eventually died in Qian Prefecture. Emperor Taizong of the Tang Dynasty had a deep father-son relationship with Li Chengqian. Although it was a big mistake for him to force the abdication and rebel, Emperor Taizong of the Tang Dynasty did not kill him in the end. Instead, he demoted him to a commoner. Li Chengqian's ending was a tragedy. He failed in the struggle for power and eventually spent the rest of his life as a commoner.

Li Chengqian deposed the Crown Prince and went to the Western Regions. The title of the novel was " The Crown Prince of the Tang Dynasty, Li Chengqian and Li Shimin."

The novels of the First Crown Prince of the Tang Empire, Tang Yu, could be read for free on many websites, such as " The First Crown Prince of the Tang Empire, Tang Yu " and " The Wind Raises the Dragon City: The First Crown Prince of the Tang Empire ". This novel told the story of a special military doctor, Tang Yu, who accidentally transmigrated to the Tang Empire and became the crown prince. He was faced with the challenges of sycophants and the invasion of powerful enemies, but he solved the internal and external problems with modern black technology.

In the novel," The Great Tang: Self-Abolishing the Crown Prince's Position at the Beginning," the protagonist, Li Chengqian, announced that he would give up the position of Crown Prince in Taiji Palace and lead more than 20 cavalry to flee the Western Regions. This move shocked the court. Several years later, when someone submitted a petition to re-appoint a Crown Prince, all the officials stood up and said that the Crown Prince was in the Western Regions to build a foundation for the Great Tang and that there was no need for another Crown Prince. Thus, Li Chengqian had been active in the Western Regions ever since he gave up his position as Crown Prince.
