Jiao Province

Jiaozhou (Chinese: ; Vietnamese: Giao Châu) was an imperial Chinese province under the Han and Jin dynasties. Under the Han, the area included Liangguang and northern Vietnam but Guangdong was later separated to form the province of Guangzhou by Sun Quan following the death of Shi Xie.

In 111 BC, the armies of Emperor Wu conquered the rebel state of Nanyue and organized the area as the bù () of Jiāozhǐ, under the rule of a cìshǐ (, ). In addition to six original commanderies (Nanhai, Hepu, Cangwu, Yulin, Jiaozhi and Jiuzhen), the Han Empire conquered new territories on Hainan Island as well as in the area south of the Ngang Pass and established them as the commanderies of Zhuya, Dan'er, and Rinan. In 203 CE, Jiāozhǐ bù was renamed to Jiāozhōu.
