The Turkic-speaking Yugurs are considered to be the descendants of a group of Old Uyghurs who fled fromMongolia southwards to Gansu after the collapse of theUyghur Khaganate in 840, where they established the prosperousGanzhou Uyghur Kingdom (870-1036) with capital near presentZhangye at the base of theQilian Mountains in the valley of theRuo Shui.[5]
In 1037, the Yugur came underTangut domination.[6] As a result ofKhizr Khoja’s invasion ofQumul, many residents who rejected conversion escaped to nearbyDunhuang andHunan in China proper. These became the ancestors of the modern Yellow Uyghurs, who have remainedBuddhists to the present day.[7]
In 1893, Russian explorerGrigory Potanin, the first Western scientist to study the Yugur, published a small glossary of Yugur words, along with notes on their administration and geographical situation.[8]
About 4,600 Yugurs speak Western Yugur (a Turkic language) and about 2,800 Eastern Yugur (a Mongolic language). Western Yugur has preserved many archaisms ofOld Uyghur.[9][10]
Both Yugur languages are now unwritten, although theOld Uyghur alphabet was in use in some Yugur communities until the end of 17th century.[11]
