Ganzhou (simplified Chinese: 赣州; traditional Chinese: 贛州; pinyin: Gànzhōu) (also formerly known in English as Kanchou) is a prefecture-level city in Jiangxi province, China。
   Its administrative seat is at Zhanggong (章贡)。In 201, Emperor Gaozu of the Han Dynasty established a county in the territory of modern Ganzhou。
   In those early years, ethnic Han settlement and authority in the area was minimal and largely restricted to the Gan River basin。
   The river, a tributary of the Yangtze River via Poyang Lake, provided a route of communication from the north as well as irrigation for rice farming。
  During the Sui Dynasty the county administration was promoted to prefecture status and the area called Qianzhou (虔州)。 During the Song Dynasty immigration from the north bolstered the local population and drove local aboriginal tribes further into the hills。
   Especially after the fall of the Northern Song capital of Kaifeng, migrants increased dramatically。 The name was officially changed to Ganzhou in the Southern Song。
  During the late 1800s Ganzhou was opened as one of the southern treaty ports and became a minor base for foreign companies。
   Between 1929 and 1934, Ganzhou formed a part of the Jiangxi Soviet, one of the bases of the Communist Party of China。
   Due to its proximity to the Red capital Ruijin (瑞金), Ganzhou was subject to a number of Kuomintang encirclement campaigns。
