Haidong District

Under the Han Empire in 121 BC e. General Huo Quibin defeated the Huns , who were wandering west of the Yellow River loop, and created the basis for a further offensive there. In 111 BC e. Generals Li Xi and Lan Zhong defeated the Qiangs who lived by the Huangshui River and founded the Xiping Post. In 61 BC e. the Qiang living in the territory of modern Haidong were brought to obedience, and the Jincheng (金城 郡) district was created, to which the counties of Yunyu (允 吾 县), Anyi (安夷 县) and Potsiang (破 羌 县) were subordinate; County authorities are located in Yunyu County. As a result of the development of the territory, the western part of the okrug was allocated in a separate district of Siping (西 平郡) in 213.

In the era of the Southern and Northern Dynasties, these lands constantly changed hands from hand to hand during wars between numerous short-lived state formations. In 397, the state of South Liang was formed , the capital of which was eventually moved to these places; in 414, it was annexed by Western Qin .

Under the Tang empire, these lands became one of the theaters of the Tango-Tibetan wars . After the fall of the Tang empire, these lands were captured by the Tibetans, who in the 11th century formed the state of Gusulo . At the beginning of the XII century, they were captured by the Tangut state of Western Xia , then the Chinese Empire of Song , then the Jurchen Empire of Jin, and in the XIII century they were captured by the Mongols. Under the Mongol Empire, Yuan Muslims began to arrive from Central Asia to Qinghai.

Under the Ming and Qing empires, most of the modern city district of Haidong was part of the Hezhou region (河 州), while the smaller part was subordinate to the Xining Council (西宁 府). After the Xinhai revolution in China, a reform of the administrative division structure was carried out, and from June 1, 1913, the provinces and councils were abolished.

After the formation of the PRC, all districts of modern Haidong until 1978 were under the direct control of the authorities of Qinghai Province. On October 19, 1978, by the decree of the State Council of the People’s Republic of China, Haidong County (海东 地区) was created, consisting of 5 counties and 4 autonomous counties.

In 1985, Minghe County was transformed into Minghe-Hui-Tui Autonomous County, as a result of which Haidong County began to consist of 4 counties and 4 autonomous counties. In 1999, Huangzhong and Huangyuan counties were transferred to Xining's jurisdiction.

In 2013, Haidong County was transformed into an urban district; the former county of Ladou has become the Ladou district in its composition.

In 2015, Ping'an County was transformed into an area of ​​urban subordination.

Haidong City District is divided into 2 districts, 4 autonomous counties:
