Before the economic center of gravity moved south, the main population of the whole country was concentrated in the north, and major wars also took place in the north. Of the seven countries in the Warring States Period, six are all in the north of the Yangtze River, and only part of the territory of Chu is in the south of the Yangtze River. When Chu and Han fought for the supremacy, Liu Bang, who occupied Guanzhong area, was obviously more dominant than Xiang Yu, who occupied the area south of Huaihe River. Xiang Yu committed suicide on the banks of the Wujiang River because there were too few troops in the south to compete with Liu Bang, who occupied the north.
After Liu Bang established the Han Dynasty, the ruling center of the Han Dynasty was still in the northern region, and most of the southern region was divided into vassals. At that time, Fujian belonged to Fujian Province, the ruling kingdom, and was not under the jurisdiction of the central government of the Han Dynasty. After Emperor Wu of the Han Dynasty conquered Fujian and Vietnam, Fujian began to be under the jurisdiction of the Central Committee of the Han Dynasty. Because the main enemy of the Han Dynasty came from the north at that time, the Han Dynasty paid little attention to Fujian, and only sent a captain south of Huiji to manage this area.
From the conquest of Fujian and Vietnam by Emperor Wu of the Han Dynasty to the chaos in the late Eastern Han Dynasty, Fujian has not been able to set up a county alone for more than 300 years. At the same time, the northern provinces are divided into several counties, and some places are even set as States. From the gap of administrative divisions, it is not difficult to see that Fujian's strategic position in the Han Dynasty was not high. During the Three Kingdoms period, Fujian built Jian 'an County. After the population of the Eastern Jin Dynasty moved south, Fujian's status gradually improved. First it was divided into several counties, and later it became a single state in the late Southern Dynasty.
Although Fujian's position has improved after the Northern and Southern Dynasties, it still does not belong to the military stronghold. The wars in the Northern and Southern Dynasties were mainly concentrated in the Huaihe River and the Yangtze River. Once the northern army broke through the Yangtze River, the southern regime had already declared its demise, and it was difficult for the war to reach Fujian. After the Sui Dynasty and the Tang Dynasty unified the whole country, the war between the Central Plains dynasty and nomadic people was mainly concentrated in the north and west, and Fujian's strategic position declined again. During the Sui Dynasty, Fujian was abolished and Jian 'an County was re-established in Fujian. During the Tang Dynasty, Fujian belonged to Jiangnan Road, and the status gap between Fujian and the northern provinces was obvious. During the Northern Song Dynasty, Fujian's strategic position was still relatively low. During the Southern Song Dynasty, due to the large-scale loss of land in the north, the southern region developed greatly. Fujian also reached its heyday in the Southern Song Dynasty. At that time, Fujian had 8 Fujian and 42 counties, which belonged to a relatively prosperous area in the Southern Song Dynasty. When the Southern Song Dynasty perished, the old ministers of the Southern Song Dynasty tried to support the young emperor to succeed in Fujian, but in the end they failed because the Yuan Army captured Fuzhou. Fujian's remote geographical location doomed its position in the unified dynasty to be not too high. Fujian can only play a certain role if a one-sided dynasty appears and dies in troubled times.
When the Ming Dynasty perished, the old ministers of the Ming Dynasty also wanted to rely on Fujian to make a comeback. As a result, the Qing army conquered Fujian and the Longwu regime was wiped out by the Qing army. After the outbreak of War of Resistance against Japanese Aggression, the Japanese army occupied a large territory in the southeast of China, but they only bypassed Fujian. The Japanese army did not attack Fujian, mainly because Fujian is vast and sparsely populated, lacking in natural resources and rugged terrain. Capturing Fujian can not only disperse Japan's forces, but also make Japan unable to obtain enough population and resources. Although Fujian was a relatively remote area in ancient times, it is now an economically developed province in China, and its economic development level has far surpassed that of Guanzhong area, which achieved the hegemony of princes in ancient times.
