 In later historiography and in modern Chinese the Tangut state is referred to as the "Western Xia" ("Xī Xià" 西夏).The Mongols and other steppe tribes referred to the Tangut kingdom as "Qashi" or "Qashin", which was derived from the Middle Chinese name for the region the Tanguts controlled ().In 881 the Tanguts assisted the Tang in suppressing the Huang Chao rebellion.
