When did the population migration in China occur in history?

Our population originally lived in the middle and lower reaches of the Yellow River. Since Qin and Han Dynasties, due to natural environment and social reasons, people's center of gravity and economic center of gravity have been moving south. Large-scale centralized population migration includes:

(1) "Yongjia mourning" period

During the Yongjia period of the Western Jin Dynasty, the decadent rulers brutally exploited and oppressed people of all ethnic groups, which led to the displacement of people in the Yellow River basin and forced them to move to the Jianghuai basin on a large scale (mainly into Jiangsu, Anhui, Hubei, Sichuan and other places). The population moving south is about 900,000, which has changed the pattern of large population in the north and small population in the south since Qin and Han Dynasties. The population in the south has increased rapidly, which has promoted the rapid economic development in the south. This is a landmark event that the population distribution center of China has shifted to the Yangtze River basin.

(B) "An Shi Rebellion" period

In the Tang Dynasty, about 6,543,800 people moved south, which fundamentally changed the population distribution pattern in China with the Yellow River basin as the center of gravity, and the population distribution ratio between the north and the south of China reached a balance for the first time.

(C) "Jingkang Rebellion" period

It happened in the Northern Song Dynasty. 1 125 years, Jin destroyed Liao and began to attack the northern song dynasty in the south. The Yellow River basin has become the main battlefield. Every major war has caused a large number of residents in the Yellow River basin to migrate to the Yangtze River basin, mainly to Zhejiang, Jiangsu, Hubei and Sichuan. This is the biggest stage of population migration in the late Northern Song Dynasty.

④ During the period of "Jin Yan Liang Hongnan Invasion"

1 16 1 Jin tore up the peace treaty with the Song Dynasty and invaded the south on a large scale. The Huaihe River basin became the main battlefield, forcing the residents of the Huaihe River basin to move south to the Yangtze River basin, mainly to Zhejiang, Jiangsu, Hunan and Jiangxi.

(5) The period of "Mongolian soldiers invading south"

After Kublai Khan ascended the throne of Khan, 1273, a large number of Mongolian soldiers invaded the south and launched a war to destroy the Southern Song Dynasty. The main battlefield is in the middle and lower reaches of the Yangtze River. In order to avoid the war, local residents migrated to the Pearl River Basin in large numbers, mainly to Guangdong, Guangxi and Fujian.

After the above-mentioned population migration, the population in the south greatly surpassed that in the north, and the south of China became the most densely populated area in China. At the same time, the social economy in the south of the Yangtze River basin has developed greatly, which can be said to be the transfer of China's population center and cultural center from the Yellow River basin to the Yangtze River basin.

(6) the period of "going west and going east"

/kloc-In old China in the late 20th century, after the invasion of Russian and Japanese imperialism, the two countries competed to expand their power in the northeast, build railways and plunder resources, which required a lot of labor, thus forcing farmers in North China to go bankrupt and move to the northeast, especially in Shandong and Hebei provinces. In addition, there are also many immigrants from Henan, Shaanxi and other provinces in Gansu, Qinghai and Xinjiang in the northwest.

(7) The period of "the southeast coast moves towards the South China Sea"

After European and American capitalism invaded Southeast Asia, in order to plunder the resources of Southeast Asia, they recruited farmers who went bankrupt in the middle of the Zhou Dynasty as labor resources to develop colonies and sold China laborers, which led to a sharp increase in the population of Southeast Asia.
