There are two direct reasons for the demise of the Daqin Empire: 1. When the capital of Qin was in an emergency, there were 300 thousand elite troops in the northern part of the empire, but they failed to hold on. Meng Tian, the general of this army, once defeated the Huns and stayed behind to guard along the Great Wall. When the capital was in an emergency, the army began to go south, but for some reason, the March was very slow. Although it is far from the capital along the Great Wall, Qin Shihuang specially built Qin Zhi Road to prevent this day from coming. If this army takes this "expressway", it will reach Xianyang City in a few days. It is strange that they didn't go to the south to fight at all. If so, the battle will be rewritten. I feel that even tarquin, who is brave and elusive, is no match for them, let alone the peasant uprising army.
In addition to the support of the north, there is a 500,000-strong Qin Jun army in the south of the empire. At the critical moment of the empire's survival, they chose silence. There is no support at all. It is said that the army behind it was directly disbanded and disappeared after the demise of Qin State.
We can understand that the two armies didn't rescue Xianyang, but the state of Qin perished, and where did the old Qin people go? What about the old Qin people who shouted * * * to go to the national disaster?
The old Qin people and the king of Qin depend on each other and trust each other. It's always been like this. Why did the old Qin people turn a blind eye this time? The origin of this matter should start with Zhao Haoqi, the king of Qin. Queen Xuan and Chu consorts held the power of Daqin for a long time, and Xiang took the opportunity to drive Chu consorts out of the court. Later, Zhao Haoqi of Qin beheaded Tian Lei, which aroused the anger of the old Qin people. After his death, Lv Buwei entered Qin, and Ying Zheng became the king of Daqin at the age of thirteen, but the power fell to Mrs Huayang and Chu consorts headed by her. The king of Qin has grown up and is nominally in power. He needed power and great cause, so he launched a war against Chu's consorts. As his great-grandfather Zhao Xiangguo Wang hoped, he would get rid of this nightmare completely.
In the thirteenth year of the King of Qin, there was a Jiao mutiny, followed by the Lao Ai rebellion, which killed a large number of generals of the old Qin people. Since then, the Kanto generals headed by Meng Tian have been ordered to command the army. So the intimate relationship between the old Qin people and the king is gone forever, and they are suspicious of each other. Daqin unified the six countries, and there were basically no generals and civil servants of the old Qin people in the court. Chu is in charge of state affairs and Kanto is in charge of the army.
It can be said that from Xiang to Qin Shihuang, the hearts of the old Qin people were deeply hurt. Although Zhang Han Li You and other generals resisted to the death, the old Qin people looked on coldly and refused to help when the Daqin Empire was tottering, so that the Daqin Empire eventually perished.
