1. Economic factors:
China's ancient economic center of gravity moved southward through three stages, which was not completely completed until the Southern Song Dynasty. From the end of the Han Dynasty to the Southern Song Dynasty, it took nearly 1 0,000 years, so the economic development level of the North always surpassed that of the South before the Southern Song Dynasty. The northern economy has been ahead of the southern economy for a long time, and Chang 'an and Luoyang were the most prosperous cities when the capital was established.
2. Topographic factors:
As for the topography of China, it is generally high in the west and low in the north, high in the south and low in the east. In the ancient cold war, high-lying areas were more conducive to defense, but difficult to attack. The flat terrain in the north is conducive to the development of agriculture.
3. Cultural factors:
The general nation likes to build its capital in the birthplace of culture, while the culture of the Han nationality mainly originated in the Yellow River basin north of the Yangtze River basin. Therefore, in order to get close to their roots, most ancient emperors chose to build their capital in the north.
4. Feng Shui factors:
In geomantic geography, the south seems to be less generous. As we all know, in ancient times, the south was regarded as supreme, while the north was marked as defeat and submission. Both the court and the temple face south, so does the emperor's seat. When he became emperor, he was called "Nan Rong". Defeat, surrender to others' "defeat" and "northern surrender".
5. Population:
In the era of ancient cold weapons, the war was about population. At that time, the most densely populated place was North China, because this area had the richest grain and the most developed economy. At the same time, the largest cities in ancient China were also in the north, such as Chang 'an, Luoyang and Xi 'an. Therefore, as long as you occupy the north, your army will have no worries and no soldiers. The advantage of making its capital in the north is that once the dynasty is threatened, the emperor and the court can quickly organize troops to fight back.
6. Resource factors
The north is rich in iron ore and good horses. Anyone who is familiar with our country's topography and specialties knows that the north is characterized by rich iron ore resources and excellent horses, which are very important to the army of the dynasty at that time.
To sum up, the reasons why most ancient dynasties chose to build their capital in the north can be divided into the above factors.
