Abstract: This essay focuses on factors that led to the origins and development of agriculture in Inner Mongolia in the early Qing dynasty as well as the relevant agriculture policies practiced by the Qing monarchs. Government support and encouragement was an essential element contributing to the rise of agriculture in Inner Mongolia. Although the Shunzhi emperor promulgated a ban on opening new land, this policy was quickly abandoned. For over 80 years, from the beginning of the Kangxi reign until the Qianlong emperor once again banned land reclamation in 1748, the government pursued a policy of developing Inner Mongolian agriculture. According to the author, it was the positive government policy that created a solid foundation for the development of agriculture in Inner Mongolia.
