Mongol conquest of Eastern Xia

In 1217, Wannu attempted a rebellion against his Mongol allies.^[7][8] This was swiftly subdued, and Wannu accepted the Mongols as his lords.^[8] In 1218, the Eastern Xia armies joined those of the Mongols in pursuit of remnants of the Khitan armies from the Later Liao dynasty which were invading Goryeo territory.^[9][10] Goryeo aided in these endeavors and accepted tributary status to the Mongol Empire and Eastern Xia.^[11] Wannu over the next decade raided into Goryeo numerous times.^[3][12] At some point after 1221, Wannu broke from the Mongols, and in 1232 the Mongol Empire requested Goryeo to attack Eastern Xia. In 1233, as part of a punitive expedition into Goryeo to force that dynasty's compliance,^[3][13] Ögedai sent Güyük and Alchidai to subdue Eastern Xia.^[14][15] The Mongol armies quickly overwhelmed Eastern Xia and Wannu was beheaded.^[9][16] The conquered territory was given to the youngest brother of the late Genghis Khan, Temüge.^[6]

The Jin dynasty fell the year after, completing the Mongol conquest of North China. The empire then, in 1235, launched invasions against Korea and the Song dynasty.^[14] The conquest of all of China would not be complete until 1279 with the Battle of Yamen.^[17]
