Song–Xia wars

The Song–Xia wars (Chinese: 宋夏戰爭) were a series of military conflicts fought by the Northern Song dynasty, Western Xia dynasty, and Liao dynasty from the late 10th century to early 12th century. Although sporadic conflicts would continue, the Northern Song lost their land border with the Western Xia after the Jin–Song wars and the Jingkang Incident of 1127 which saw the fall of their capital, Kaifeng, to the Jurchen-led Jin dynasty.
