In the late Ming and early Qing dynasties, the population of Sichuan decreased sharply due to the war. At the end of the Ming Dynasty, the Qing army and Zhang Jun fought fiercely in Sichuan, and the long-term war made the population of Sichuan decrease rapidly. After the Qing dynasty suppressed Zhang's peasant uprising army, Sichuan finally gained stability for a period of time. But Emperor Kangxi decided to cancel San Francisco, and Wu Sangui, the king of Yunnan, withdrew. Wu Sangui launched a rebellion under the banner of anti-Qing and regaining sight. This time, the battlefield is still in Sichuan, and the people of Sichuan have suffered from war. After the war, the population of Sichuan dropped to a low point. The rulers of the Qing Dynasty thought that Sichuan's population was too low, which was not conducive to economic recovery, so they let people from Huguang area live in Sichuan under the official organization. This is the saying that Huguang fills Sichuan.
However, it was not only in the Qing Dynasty that Huguang filled Sichuan. Sichuan has a very good geographical position and is suitable for agricultural production. As early as the Southern Song Dynasty, the population of Sichuan was about 6.5438+million, which contributed a lot of tax revenue to the Southern Song Dynasty court. Only after the demise of the Song Dynasty, the Yuan army attacked Sichuan, which was destroyed by the war, and the population suddenly dropped to several hundred thousand. The Yuan government did not manage Sichuan, nor did it want to adjust the population. By the Ming dynasty, the Ming government realized that a place as big as Sichuan was too small in population, so it organized people around Sichuan to move to Sichuan, which was also the early Huguang filling Sichuan movement.
As can be seen from the above, Sichuan can be regarded as an immigrant province. Most people immigrated from neighboring provinces. Although Sichuan has suffered so much, it is now a very developed province.
