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

The Western Xia was a Tangut-led Chinese dynasty which ruled over what are now the northwestern Chinese subdivisions of Ningxia, Gansu, eastern Qinghai, northern Shaanxi, northeastern Xinjiang, southwest Inner Mongolia, and southernmost Outer Mongolia from 1032 until 1227 when they were destroyed by the Mongols. The country was established by the Tangut people; likewise its earliest coins were escribed with Tangut characters, while later they would be written in Chinese. Opposed to Song dynasty coins that often read top-bottom-right-left, Western Xia coins exclusively read clockwise. Despite the fact that coins had been cast for over a century and a half, very little were actually produced and coins from Western Xia are a rarity today. Although the Western Xia cast their own coins barter remained widely used.
