Circuit (political division)

A circuit is an appealate judicial district among the courts of many nations. The name comes from an era in which justices would ride within a area hearing cases.


Circuit (道 ; Chinese: dào; Japanese: dō) was a Chinese political division, and is a Japanese one. In Korea, the same word 道 (도; Do) is translated as "Province."

China

It originated in China in 627, when Emperor Taizong (唐太宗) subdivided China into ten circuits. Emperor Xuanzong (玄宗) further added 5. It was abolished as the highest administrative divisions when the Qing Empire collapsed in 1911. However, circuits still existed as high-level, though not top-level, divisions of the Republic of China, such as Qionyai Circuit (now Hainan Province). In 1928, all circuits were replaced with committees or just completely abandoned.

Circuits were the highest of the three-tier system (三級制), the next two are prefectures (州) and districts (縣). They are simultaneously inspection areas (監察區 jian1 cha2 qu1).
