Hangchou

The Emperor Kao-tsung (1107-1162), whose official name was Kou, and whose familiar name was Te-chi, was the ninth son of the Emperor Hui-tsung. At first he was entitled Prince of K'ang, but on the two emperors Hui-tsung and Ch'in-tsung being taken north as prisoners by the Khitan he established himself as emperor in Hangchou.

The Sung Dynasty is divided into a Northern and Southern Sung, the former when the capital was at Kaifeng, and the latter when Hangchou was the capital.

When the dust settled, there was the Chin dynasty with its own emperor plus two Sung emperors as prisoners in the north, and Kao-tsung, the first emperor of the Southern Sung, in Hangchou.
