The Ganzhou Uyghur Kingdom (traditional Chinese: 甘州回鶻; simplified Chinese: 甘州回鹘; pinyin: Gānzhōu Huíhú), also referred to as the Hexi Uyghurs (traditional Chinese: 河西回鶻; simplified Chinese: 河西回鹘; pinyin: Héxī Huíhú), was a Turkic dynastic state ruled by the Uyghur Yaglakar clan. It was established in 894 around Ganzhou in modern-day Zhangye, and lasted until 1036. During that time, many of Ganzhou's residents converted to Buddhism.
The Hexi Corridor, located within modern Gansu, was traditionally a Chinese inroad into Central Asia. From the 9th to 11th centuries this area was shared between the Ganzhou Uyghurs and the Guiyi Circuit. By the early 11th century both the Uyghurs and Guiyi Circuit were conquered by the Tangut people of the Western Xia dynasty.
