Foreword
The Qin Dynasty, with its domineering and ambition to unify the six kingdoms, created the first great unified dynasty in Chinese history. However, who would have thought that just fifteen years later, the once invincible Qin Empire would come to an end. What is even more puzzling is that the Qin Dynasty still had a huge army at that time, numbering as many as 800,000, but they did not seem to have played any role in saving the Qin Dynasty's demise. Why is that?
1. The historical background of the fall of the Qin Dynasty
Let's first return to the historical background of the Qin Dynasty. After Qin Shi Huang unified the six kingdoms, in order to consolidate the rule of the empire, he implemented a series of reforms, such as the introduction of Legalism, the unification of writing, and weights and measures. However, these reforms have not been genuinely embraced by the people everywhere. Under the harsh rule of Qin Shi Huang, the common people lived in hardship, and the mood of rebellion gradually grew.
Two: Why did the Qin Dynasty fall
1: Most of the Qin Dynasty's armies were stationed in the frontier areas to defend the newly conquered lands. When the uprising of Chen Sheng and Wu Guang broke out, the lag in the transmission of information prevented most of the Qin troops in the frontier from returning in time. Even though part of the army was recalled, the morale and combat effectiveness were seriously affected due to the long period of conquest and garrisoning.
2: In the process of unification and establishment of the Qin Dynasty, Qin Shi Huang's excessive investment in military affairs led to the exhaustion of the Qin army. In addition, the Qin army suffered heavy losses in the war of unification, and its combat effectiveness declined significantly, making it difficult for it to cope with external threats.
3: The internal contradictions of the Qin Dynasty are also reasons that cannot be ignored. Qin Shi Huang's eldest son, Fusu, repeatedly advised his father to reduce his conquests and reduce the burden on the people, but he was refused and was eventually forced to commit suicide. The youngest son of Qin Shi Huang, Hu Hai, was a mediocre and incompetent monarch, which led to chaos in the government and the eunuch Zhao Gao monopolized power. Such internal strife prevented the Qin army from concentrating its forces against external enemies.
4: Let's look at geography. When the rebel army captured Hangu Pass, the gateway to the Guanzhong area was wide open, and Xianyang City was in danger. However, due to the Qin army stationed in the border area, the long and difficult way to return to help, coupled with the inconvenient transportation, made it impossible for them to rush to Xianyang in time to rescue.
Three: Reflections on the fall of the Qin Dynasty
Based on the above reasons, we can understand why the 800,000 Qin army failed to save the Qin Dynasty. This is not only a historical necessity, but also an interweaving of various accidental factors.
From this point of view, the fall of the Qin Dynasty was not a simple military defeat, but the result of a combination of factors. It offers us a valuable lesson: the stability of a dynasty does not depend on force alone, but also requires popular support, effective governance, and internal unity.
Four: Summary
History is a complex process, and there are often many factors and backgrounds for the occurrence of an event. Therefore, when looking at historical issues, it is necessary to analyze them comprehensively and objectively, and cannot simply reduce them to a single cause. Only by having an in-depth understanding of the truth of history and the reasons behind it can we better provide reference and enlightenment for future development.
