The reasons of immigration in Qin dynasty

When Qin immigrated to Sichuan for the first time, he moved 10000 households. According to a family of four or five, there are 40,000 or 50,000 people at most. This is the first migration in Sichuan history. But this is just the beginning. In fact, many fugitives and displaced people have brought their wives and sorrows to Sichuan since Qin began to emigrate to Sichuan. The second migration, to the Eastern Jin Dynasty at the end of the Eastern Han Dynasty, divided the masses, plunged the Central Plains into chaos, and a large number of people died in chaos or scattered around.

Refugees and bureaucrats all over the country have avoided this situation. At that time, the stable and prosperous Yizhou area almost became the first direction for the victims. The third group of immigrants and exiles took refuge in Chengdu. The most typical ones are the Tang Dynasty and the Five Dynasties and Ten Kingdoms. After Anshi Rebellion and Huang Chao Rebellion, the late Tang regime finally collapsed in the storm. This country has entered the most chaotic period in China. Prince rule, Beowulf in power, frequent wars. Although the time is short, dynasties change frequently. This is the history of five dynasties and ten countries.

In the fourth migration, Sichuan had the strongest resistance to Mongolian troops at the end of Song Dynasty and the beginning of Yuan Dynasty. Therefore, according to the custom of the Mongolian army, Sichuan also suffered the most violent revenge and slaughter, and its population suddenly dropped from 6.5438+million to nearly 800,000. The practical significance of Sichuan in the Song Dynasty was just a name. This is the fourth largest immigrant in Sichuan history. Immigrants in the early Ming Dynasty mainly came from Huguang, including parts of Hubei, Hunan, Guangdong and Guangxi. About 300,000 immigrants came to Sichuan. During the five immigrants in the late Ming and early Qing dynasties, Zhang's crazy talk made Sichuan suffer the most painful loss in history.

From Shunzhi and Kangxi years, the Qing Dynasty gradually implemented the policy of encouraging people from northern and southern provinces to enter Sichuan. The migration activity in this century is also the fifth largest migration in Sichuan history. 1937 after the outbreak of War of Resistance against Japanese Aggression, the national government moved to Chongqing, and then moved many factories, schools, enterprises and institutions. The eastern population also moved in. After the founding of New China, China People's Liberation Army (PLA) went south, the third-line construction, reform and opening up, and the Three Gorges immigrants, and Sichuan and Chongqing ushered in a new round of immigrants in history.
