As the ancient capital of six dynasties, why was Xi'an abandoned by later kings?
Most people in ancient times attached great importance to Feng Shui. Especially when the emperor chose the capital, he attached great importance to the landscape and carefully studied the surrounding environment. From a geographical point of view, Xi'an's location is very good. This city is very close to the Yellow River and is blocked by mountains on three sides, making it difficult to defend and attack. It is very good to set the capital at this place. In addition, the Guanzhong Plain near the Yellow River has developed very well and is very conducive to people's production. What is the reason why no emperor chose this place to build his capital after the Tang Dynasty?
In fact, this needs to be analyzed from many aspects. At the beginning, Zhao Kuangyin set the capital in Kaifeng. The main reason for this was that after Xi'an experienced the Anshi Rebellion, it also experienced many wars, large and small, which caused serious damage to local buildings. If the capital is chosen in this place, it will require a lot of financial and manpower to repair the city, and it will also take a lot of time, which is very detrimental to the consolidation of the political power. The city of Kaifeng was positioned as a second-tier city during the Tang Dynasty. Therefore, after experiencing the turmoil, it was not seriously damaged and could still be used.
If coincidence and fate are ignored, Xi'an has a huge drawback, which is economic development. During the Sui and Tang Dynasties, due to the influence of geography, the economy in the Jiangnan area developed rapidly and was called the granary of the world. However, Xi'an during this period was already an ancient capital. The geographical environment was severely damaged, and agricultural production capacity also dropped a lot. At this time, if the supply of food cannot keep up, problems will inevitably arise in the dynasty.
After experiencing the Anshi Rebellion, Chang'an, which was in desperate need of recovery, developed an unforgettable dependence on Jiangnan. However, there were some problems with the local supply of food at that time, and the failure to replenish it in time caused panic in the city of Chang'an. Of course, the reason why Xi'an was abandoned is not only these, but also affects the country's planning for the strategic defense center.
Before the Tang Dynasty, most of the main enemies came from the northwest region. After the Tang Dynasty, most of the enemy armies were from the Northeast. For the farming society at that time, if you wanted to choose a city as the capital, the first condition was that it must be very close to the battle line, so that the security and stability of the country could be effectively guaranteed.
If the capital is too far away from the battle line, transportation development was very backward at that time, which will inevitably bring great pressure on information update and mobilization. If a large number of troops are placed far away from the capital, It is very likely to lead to the emergence and growth of local forces.
Therefore, when choosing the location of the capital, it also has a great relationship with the security pressure of the country. In general, the reason why Xi'an was abandoned was a mixture of accident and necessity~
