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