Historical evolution

Name and origin

The name of "Dengkou" originated from the old Dengkou (now the residence of bayinmuren Sumu, azuo banner, Alxa League). "Deng", stone steps. The Yellow River flows to Dengkou in a north-south direction. Dengkou is on the West Bank of the Yellow River. Because the base of the channel is hard, the river is not easy to wash, and the upper layer is covered with loose sandy loam, which is easy to wash. In this way, the water rises and falls, leaving a step after step. Dengkou is also an important ferry for the east-west traffic of the Yellow River, hence its name.

Evolution of organizational system

After the Qin Dynasty unified China, it belonged to the new Qin Dynasty.

During the reign of Emperor Wu of the Han Dynasty, Shuofang county was set up, with ten counties under it. Yuhun, LINRONG and Sanfeng were all located in Dengkou. They were once prosperous reclamation areas in Shuofang during the Han Dynasty, with a population of more than 70000.

In the Northern Wei Dynasty, Dengkou belonged to xiazhou; in the Tang Dynasty, it belonged to xiazhou Jiedushi.

In the Song Dynasty, the Dangxiang clan gradually strengthened and established the Xixia Dynasty, where the German army returned to heaven.

During the reign of Emperor Qianlong, Dengkou was selected as the Jilantai Salt export terminal, and a government office was set up with officers stationed, which promoted the development of local handicraft industry, agriculture and Commerce in Dengkou.

In 1926, after general Feng Yuxiang took the oath of Wuyuan, he advanced westward and passed Dengkou to provide convenience for military supplies and connect with Suigan corridor. So he decided to set up "Dengkou military station". In January 1929, with the approval of Nanjing National Government, he set up a county, which belonged to Ningxia. After liberation, Dengkou county was still under the jurisdiction of Ningxia.
