The Uyghur Khaganate was a Turkic empire that existed for about a century between the mid 8th and 9th centuries. It was a tribal confederation under the Orkhon Uyghur (回鶻) nobility, referred to by the Chinese as the Jiu Xing, a calque of the name Toquz Oghuz or Toquz Tughluq.

The Tang dynasty, or the Tang Empire, was an imperial dynasty of China that ruled from 618 to 907, with an interregnum between 690 and 705. It was preceded by the Sui dynasty and followed by the Five Dynasties and Ten Kingdoms period. Historians generally regard the Tang as a high point in Chinese civilization, and a golden age of cosmopolitan culture. Tang territory, acquired through the military campaigns of its early rulers, rivaled that of the Han dynasty.
