The Eastern Xia, also known as Dongxia, Dongzhen (東真), or Dazhen (大真), was a short-lived kingdom located in Manchuria. It was established in 1215 by the Jurchen warlord Puxian Wannu during the period of the Mongol conquest of the Jin dynasty.
The kingdom was eventually conquered by the Mongols. Following its collapse, the former territories of the Eastern Xia were administered by the Liaoyang province of the Yuan dynasty.
