Puxian Wannu

While Mukhali of the Mongol Empire invaded Northern China, Puxian Wannu rebelled against Jin and founded the Dazhen (大眞) kingdom in Dongjing (Liaoyang) in 1215.

As a result of an internal strife in the Eastern Liao, Yelü Liuge was expelled and sought support from Genghis.

Puxian Wannu capitulated to Mukhali's army and sent his son Tege Qorči [ja] (铁哥/鐵哥 Tiěgē) as a hostage in 1216.

In 1218 the Mongol and Eastern Xia armies jointly intruded into Goryeo to subdue the Khitan remnants.

In 1233 Ögedei's son Güyük attacked Eastern Xia with a large force and captured Puxian Wannu.
