In the second year of Zhenyou (1214)

after fierce controversy

Emperor Xuanzong of Jin moved the capital to the Southern Capital (now Kaifeng

Henan). Then

the Jurchens went south

which was the fourth large-scale southward migration of the Jurchens after those led respectively by Emperor Taizong

Xizong and Hailing. The Jurchens who moved to the south were concentrated in different parts of Henan with the Southern Capital as the center

and parts of Jiangsu and Anhui today. The Jurchens’ southward migration was forced by the Mongols’ attacks. Although it strengthened the anti-Mongol forces in Henan and other places

it destroyed the military deployment in the north

increased the burden on people in Henan and other places

caused serious social problems

and accelerated the demise of the Jin Dynasty to a certain extent.
