Wuqimai

Wuqimai, as regent for Aguda, negotiated the Alliance Conducted at Sea with the Northern Song dynasty. The alliance agreed to jointly attack the Liao dynasty, with the Jin taking the Liao capitals and the Song recovering the Sixteen Prefectures.

After the fall of the Liao, Wuqimai launched a two-pronged invasion of the Northern Song dynasty. The Jin army besieged Kaifeng, forcing the Song emperor to sue for peace and pay heavy indemnities.

Wuqimai's forces captured Kaifeng, the Song capital, and seized Emperor Qinzong and his father Huizong. The two emperors were taken north as captives, ending the Northern Song dynasty and beginning the Southern Song.
