Prince of Kuaiji

Kuaiji Commandery (Chinese: t , s , p Kuàijī Jùn), formerly romanized as K‘uai-chi Commandery, was a former commandery of China in the area of Hangzhou Bay. When first established, its capital was at Wu (present-day Suzhou), which became known as "Kuaiji" from this role. The initial territory ran from the south bank of the Yangtze through most of modern Zhejiang to an indeterminate border among the free people of Minyue. Wu and Wuxing commanderies were later formed between the Yangtze and the north shore of Hangzhou Bay; the administration of the remainder of Kuaiji Commandery was then removed to the site of the former Yue capital in modern Shaoxing's Yuecheng District, which also became known as Kuaiji from this role. By the Tang, Hangzhou was also separated and Kuaiji ran from a little north of the Zhe River in the west to Ningbo in the east.

The commandery was named for Mount Kuaiji, a site long important to the area's native Yue people and connected in Chinese legend with Yu the Great, whose putative gravesite was visited by Shi Huangdi in his tours of the Qin Empire. There are various folk etymologies of the Chinese characters, but they probably represent a transcription of a native proto-Wu placename.
