The Tangut people were a Sino-Tibetan people who founded and inhabited the Western Xia dynasty. The group initially lived under Tuyuhun authority, but later submitted to the Tang dynasty. After the collapse of Tang dynasty, the Tanguts established the Western Xia. They spoke the Tangut language, which was previously believed to be one of the Qiangic languages or Yi languages which belong to the Tibeto-Burman family." Phylogenetic and historical linguistic accounts, however, reveal that Tangut belonged instead to the Gyalrongic branch of Tibeto-Burman. Western Xia was annihilated by the Mongol Empire in 1227, most of its written records and architecture were destroyed. Today the Tangut language and its unique script are extinct; only fragments of Tangut literature remain.

Tangut is an extinct language in the Sino-Tibetan language family.
