History
Turpan has long been the centre of a fertile oasis (with water provided by the karez canal system) and an important trade centre. It was historically located along the Silk Road, at which time it was adjacent to the kingdoms of Kroran and Yanqi. The name Turfan itself however was not used until the end of the Middle Ages - its use became widespread only in the post-Mongol period. The center of the region has shifted a number of times, from Yar-Khoto (Jiaohe, 10 km to the west of modern Turpan) to Qocho (Gaochang, 30 km to the southeast of Turpan), and to Turpan itself. Historically, many settlements in the region have been given a number of different names, some of which refer to more than one place – Turpan/Turfan/Tulufan is one such example. (Others include Loulan/Kroran/Korla, Jushi/Gushi, Gaochang/Qocho/Karakhoja, Hezhou, and Jiaohe/Yarkhoto.)
