In history, Turpan was the capital of ancient Gaochang Kingdom (from the sixth century) and later the administration residence of Xizhou. The depression was the center (A.D. 200–400) of a flourishing civilization in which Indian and Persian elements were combined. This civilization was later absorbed by the Uygurs, who had their capital at nearby Gaochang (9th–13th century).
Turpan used to be an important strategic point on the Silk Road. As early as two thousand years ago, a town called Jiaohe was built forth kilometers from today‘s town of Turpan. Jiaohe then was the capital of the Outer Cheshi Kingdom. During the first century, Jiaohe came under the rule of the Han Dynasty. During the sixth century, Turpan was under the administration of Gaochang Kingdom. During the reign of Emperor Tai Zong (626-649), the Tang Dynasty conquered the Gaochang Kingdom, and Turpan again became a frontier town of China, serving as a stopover for merchants, monks, and other travelers on their way to the west.
