Jiujiang's history dates back over 2,200 years to the Qin Dynasty, when it was established as a county. Its name "Nine Rivers" reflects the confluence of waterways that made it a natural trading port. During the Three Kingdoms period (220-280 AD), Jiujiang was a strategic military stronghold for the Wu Kingdom.
Under the Tang Dynasty, Jiujiang flourished as a commercial center along the Yangtze River. The famous poet Bai Juyi served as an official here and wrote about the city in his works. During the Song Dynasty, the city became a major hub for ceramic exports from nearby Jingdezhen, with Lushan marble and timber also passing through its ports.
The Opium War and the Treaty of Nanjing (1842) forced Jiujiang to open as a treaty port. Foreign concessions were established along the waterfront, and Westerners built churches, warehouses, and villas. This colonial period left a lasting architectural legacy and exposed the city to international trade.
After 1949, Jiujiang developed into an industrial center, with particular strengths in petrochemicals, shipbuilding, and textiles. The reform and opening-up policy after 1978 accelerated its growth. In 1992, Jiujiang was designated as one of the Yangtze River Open Cities, attracting foreign investment. Today, the city balances industrial development with ecological preservation of Lushan and Poyang Lake.
