Ēnzhōu

Enzhou was a prefectural seat on the plain of northwestern Shandong. Its name dates to 1048, when the Song official Wen Yanbo suppressed Wang Ze's rebellion and petitioned to rename Beizhou as Enzhou. The prefecture once governed territory extending into what is now Hebei as well as western Shandong. In 1369, the early Ming reduced Enzhou to En County, which came under Gao Tang department in Dongchang prefecture.
