Counting the founding emperors of China's dynasties and dynasties, either Wen Taowu is slightly added to one, or the role of civilian counterattack, all of them are heroic and strategic. According to the five major dynasties of the Tang, Song, Yuan, Ming, and Qing dynasties, such as Zhao Kuangyin of the Song Dynasty, Genghis Khan of the Yuan Dynasty, Zhu Yuanzhang of the Ming Dynasty, and Nurhaci of the Qing Dynasty, everyone can be called the originator of the founding of the country, and they are also highly respected by future generations. Only Li Yuan, the founding emperor of the Tang Dynasty, was even less famous than several generations of emperors in later generations.
Chairman Mao, the great leader of our country, was very fond of reading, and he would write down his own observations on many important things recorded in the book, such as his evaluation of Qin Shi Huang was very high, saying that no emperor in the future could compare with him. And also commented that Liu Bang, the ancestor of Han Gao, was the most powerful one among the emperors of feudal society. But when he mentioned Li Yuan, he only wrote a sentence next to him, "There is no decisiveness in case of trouble", and it was hastily done.
In fact, as long as you look through the relevant books on the history of the founding of the Tang Dynasty, you can find the answer from it, and Li Yuan is definitely not without reason for being evaluated by Chairman Mao. He showed great hesitation in many battles when he overthrew the Sui Dynasty and established the Tang Dynasty, and even wanted to give up at many favorable opportunities, if it were not for Li Shimin's persuasion, I am afraid that our "Tang Dynasty" would have been drowned in history.
At that time, in the late Sui Dynasty, because the Sui Emperor lived a luxurious life and reused eunuchs, the government and the public at that time were in turmoil. Just as we saw in the TV series "The Legend of sui and Tang heroes", many princes and people at that time took advantage of this opportunity to completely overthrow the ruling power of the Sui Dynasty. Li Yuan was one of the many rebel armies at that time.
Li Yuan and the Sui Emperor Yang Guangben were relatives, and in the feudal dynasty at that time, the emperor was very taboo about some superstitious claims. At that time, a eunuch who had a vendetta against Li Yuan found a warlock and asked the warlock to spread the rumor that "Li Shi should be the son of heaven" through inducement. This statement quickly spread at that time, and soon reached the ears of the Sui Emperor, making the Sui Emperor very wary of Li Yuan at that time, and even planned to take the opportunity to kill him.
At that time, Li Yuan had already discovered that the situation was not quite right, and began to pretend to be crazy and stupid, playing a liquor-colored person with no ability, thus successfully deceiving the Sui Emperor. Later, the domestic princes rebelled against the Sui Dynasty one after another, and the rebel armies marched from all directions to the capital of the Sui Dynasty, and when the Sui Emperor saw this situation, he appointed Li Yuan at that time as the remainer of Taiyuan to resist these rebellious forces.
However, under the situation at that time, the Sui Dynasty Emperor was already the target of public criticism and was unpopular. Li Shimin also began to persuade his father Li Yuan to establish himself as king, but Li Yuan did not agree. It was not until later, when the Turks defeated the Sui army under the command of Li Yuan at the time, that Yang Guang wanted to take Li Yuan and question him.
Li Shimin took this opportunity to hurriedly submit a request to Li Yuan for an uprising, and Li Yuan also understood that if he really went to Yang Guang, heng and vertical would be a death, so he decided to revolt.
The idea of an uprising had not been decided for long, and Yang Guang gave up the decision to punish Li Yuan because there was no one available. And this Li Yuan is also strange enough, once he sees that there is no danger, he does not want to revolt. Li Shimin persuaded Li Yuan for a long time at that time before he persuaded Li Yuan to take "Tang" as the national name and officially began to send troops to attack Chang'an.
Not only that, Li Yuan also wanted to give up many times on the road of the uprising, even under the premise that he had a great advantage at that time. In the end, when Li Shimin saw that Li Yuan was indecisive, he directly knelt down on the spot and cried unceasingly, persuading Li Yuan not to withdraw his troops under any circumstances.
Li Yuan's indecisiveness and lack of talent in his heart are definitely not just talking. At that time, Li Yuan's army was already under the city of Chang'an, and seeing that the victory was in hand, he was about to call the emperor emperor, and this opportunity was what many people dreamed of. However, Li Yuan hesitated again, he felt that this was against the Way of Heaven and would be considered by the people of the world as a villain who plotted rebellion.
In 618, Li Yuan officially declared himself emperor and established the Tang Empire, which had flourished in Chinese history. However, on the way to Li Yuan's army, it really made Li Shimin and many courtiers break their hearts and break their mouths. If it were not for Li Shimin's mediation, the Tang Empire would really have ceased to exist.
Conclusion: Later, it was the well-known Xuanwumen Change, li Yuan was controlled by the li yuanji brothers in his imperial city, which was also the only founding emperor among the founding emperors of the Chinese dynasties who was controlled within his own palace. After Li Shimin ascended the throne, Li Yuan became emperor Taishang. This is also enough to see that although this Li Yuan is nominally the founding emperor, he really did not make as much contribution as Li Shimin to the establishment of the Tang Dynasty.
