Huangchuan County (simplified Chinese: 潢川县; traditional Chinese: 潢川縣; pinyin: Huángchuān Xiàn; local pronunciation: Huāngchuǎn Xiàn) is a county of southeastern Henan province, People's Republic of China. It is located in the center of Xinyang City, straddling the Huang River. That is why it is named Huangchuan, meaning where Huang River flows.
Origin and early development
Recorded in Bamboo Annals, Huangchuan was settled as a tribe of Huang during Xia Dynasty, in the 21st century BCE. In the beginning of Zhou Dynasty, Huang was founded as a vassal state, which is considered root of the Chinese surname Huang. Huang was counquered by Chu in 648 BCE, during the Spring and Autumn Period.
According to Brief Sketch of North Parts of Ming Dynasty (Chinese: 明季北略), a book by Ji Liu-qi (Chinese: 计六奇) recording the transitional period from the Ming to the Qing, Huangchuan (then Guangzhou) was devastated and the residents massacred by the peasant army. And now residents in Huangchuan are mainly descendants of migrants from Jiangxi, Fujian and Guangdong settled down during the period of Kangxi.
In 1913, Huangchuan was renamed to its current name.
In 2009, Huang-Guang Integration project was launched aiming to integrate Huangchuan County and neighboring Guangshan County.
