What was the period of several large-scale southward migrations of the Central Plains in ancient China?

On a large scale, there are three times.

The first time was in the Jin Dynasty. In the Western Jin Dynasty (AD 290-306), the Eight Kings Rebellion occurred, and the rule was severely weakened. Then the nomadic people in the west and north coincided with the cold climate, unsustainable water plants and difficult life. Therefore, nomadic people migrated to the Central Plains on a large scale, which is said in old history books. This, in turn, led to the indigenous people in the Central Plains moving southward and entering the Jiangnan area on a large scale.

The second time was after the Anshi Rebellion in the Tang Dynasty (755-763). The armies of An Lushan and Shi Siming fought bravely and treated the people more fiercely. The Central Plains region, represented by Luoyang, suffered large-scale destruction. This in turn prompted China aborigines to move southward on a large scale.

The third time was in the Song Dynasty. Due to the rise of nomadic peoples in the north and northwest, such as the Khitan nationality to which Feng Xiao belongs, the Jurchen nationality to which Akuta belongs, the Mongolian nationality to which Genghis Khan belongs, and the Tangut to which Xixia belongs as mentioned in "Tianlong Babu", "First Class Hall" has been set up, and the wars in the northern and northwest borders have continued, leading to the final demise of the Northern Song regime in the hands of the Jurchen nationality. The population of the Central Plains once again moved southward on a large scale.

The above three times were all due to the influence of nomadic people in the north or northwest going south. Because nomadic people rely on the advantage of force and make a living by large-scale looting, not agricultural production. This has caused great losses to farmers. In the early days after nomadic people went south, it always triggered a large-scale migration of residents. From the 2nd century BC to 1 century AD, the Han regime expelled the northern nomadic Huns, which triggered a large-scale ethnic migration on the Eurasian grassland. This was the largest national migration activity before the large-scale western colonization in modern times, which eventually led to the demise of the Roman Empire like a domino.

However, after a period of time, the nomadic regime will gradually accept the ruling strategies and methods of the Central Plains and will gradually stabilize. For example, Manchu in Qing Dynasty.

Take a look at some finishing work.

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.

2. "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.

3. "Jingkang Rebellion" Period

It happened in the Northern Song Dynasty. 1 125, 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. Jin Yan Hong Liang period

1 16 1 Jin tore up the contract 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 and others arrived at Khan's position, 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 escape the war, a large number of local residents moved to the Pearl River Basin, mainly in Guangdong, Guangxi and Fujian.
