The Tang Dynasty (6 18-907) was a unified Central Plains dynasty after the Sui Dynasty, with a total of 2 1 emperor and enjoyed the country for 289 years. After Emperor Xuanzong of the Tang Dynasty ascended the throne, he created a prosperous new century and reached the peak of the Tang Dynasty. At the end of Tianbao, the national population reached about 80 million. After the Anshi Rebellion, separatist regimes and eunuch dictatorship appeared one after another, and the national strength gradually declined.
"The Change of Xuanwu Gate" can be said to be the most famous coup in the Tang Dynasty and even in the ancient history of China. Emperor Taizong became the emperor of the Tang Dynasty, which became a psychological shadow that he never really got rid of in his life. Moreover, for various reasons, many people in later generations have all kinds of sympathy for the loser Li.
But in fact, before the Xuanwumen Revolution, Li gained the upper hand, and the coup launched was a Jedi counterattack. In a sense, Li was "culpable of punishment", but he lost his life with a huge advantage. So what advantages did Li have before the "Xuanwu Gate Change"?
First of all, the dispute with Li is essentially the contradiction between the hero group represented by Li Yuan and the imperial power represented by Li Yuan. So Li took advantage of the power contradiction between and attacked the Qinwang Group many times. Even Fang and Du Ruhui were transferred from the Qin Palace.
In the ninth year of Wude (626), Li planned to take advantage of the Turkish invasion of the border and destroy all the military commanders of Qin State. If the plan is successful, Li Shimin Group, the King of Qin, will be eliminated politically, thus forcing Li Shimin to launch the "Xuanwu Gate Change". In the whole "Battle of the Prince", Li always occupied the political advantage.
Secondly, before the "Xuanwumen Revolution", Prince Li had the command of some garrison troops in Chang 'an, and he also publicly formed 3,000 Chang 'an Army. Together with the original Eastern Palace Guard and Peace Corps, Li Ying's strength is about 5,000 to 6,000. Li Shimin has only 800 troops in Chang 'an.
Therefore, during the "Xuanwumen Rebellion", almost all people who could carry weapons, including Li Shimin, took part in the coup, and Gao Shilian, the uncle of the eldest grandson, even went to the prison to launch prisoners to participate in the war. If Li hadn't been killed at the beginning of the coup, he might not have won the "Xuanwumen Change".
Generally speaking, before the Xuanwumen Revolution, it occupied a huge advantage in political strength and military strength, but it was at a disadvantage. If Li himself hadn't made all kinds of mistakes, it would be difficult to win the "War of the Prince" and there would be no brilliant "Zhenguan Rule" later.
