In 751 of the Tang Dynasty, Songjiang was named Huating County. In 1277, during the Yuan Dynasty, it was named Huating Prefecture, which was changed to Songjiang Prefecture the next year. Then, in 1805, in the Qing Dynasty, it was developed into Songjiang Prefecture with Huating, Shanghai, Qingpu, Lou, Fengxian, Jinshan, Nanhui, and Chuansha Counties subject to it. In 1912, when the prefecture was abolished, Huating and Lou were merged into Huating County of Jiangsu Province. In 1914, Huating County was changed to Songjiang County. After liberation, the area became Songjiang Special District. In March 1958, it was merged into Suzhou Special District, and in November, Songjiang became a county of Shanghai. Then, in February 1998, the State Council approved Songjiang as a district.
