Answer:
The Song dynasty was the second great "medieval" period of China. But unlike the Tang, it coexisted uneasily with powerful rivals to the north. These rivals were the Khitan Tartars of Manchuria and Mongolia, kept at bay only through costly bribes, and the Jurchen people of Central Asia, who were intent on conquering China but could not be influenced by payoffs. While the Song dynasty managed to recapture—and develop—much of the glory of the Tang, it did suffer a blow in 1127 when the Jurchen took the capital of Kaifeng, and sent the Song Chinese administration southward, to establish the Southern Song capital at Hangzhou, near modern Shanghai. Still the Northern Song (while it lasted) and the Southern Song (from 1127 until 1279) achieved incredible feats of learning, science, art, and philosophy. To the Chinese, the Song was a period certainly as great as the Tang.
