07 · History

How Haimen took shape

Haimen is a district of Nantong, Jiangsu province, located on the northern bank of the Yangtze River estuary. Historically famous for fishing and salt production, the area has developed into an important port-based industrial hub.

How did Haimen evolve through history and modern administration?

The territory of Haimen formed originally from silt deposits originating from the Yangtze River, with sandbanks like Dongzhou and Buzhou joining the mainland during the Tang dynasty. Haimen County was established in 958 CE during the Later Zhou dynasty with its seat at Dongzhou Town, though it was subsequently merged into Tongzhou District. Shifting river courses and northward movements of the Yangtze River mouth during the Ming dynasty brought severe flooding that destroyed parts of the county, including Lüsi, Yudong, and Sijia. Under the Kangxi Emperor of the Qing dynasty, the administrative seat relocated to Jinghai Township in 1672, and subsequent southern shifts in the river course generated over forty new sandbanks, leading to the establishment of an independent subprefecture with its seat at Maojia Town in 1768.

During the late Qing period, industrialist Zhang Jian was born in Changle Town, founding the Dasheng Cotton Mill in 1895 to catalyze China's modern textile industry. Haimen transitioned back to a county in 1912 following the establishment of the Republic of China, and fell under the governance of Nantong Prefecture when the People's Republic of China was founded in 1949. The area regained county status in 1983, advanced to a county-level city in June 1994, and was formally integrated as a district of Nantong in 2020.
