Dongxia, also known as Dongzhen or Dazhen, refers to a short-lived kingdom established in Manchuria during the early 13th century. It was founded in 1215 by the Jurchen warlord Puxian Wannu amidst the Mongol conquest of the Jin dynasty.
The kingdom was eventually conquered by the Mongols. Following its collapse, the territories formerly held by Dongxia were administered as part of the Liaoyang province under the Yuan dynasty.
