Tangut script
The Tangut people founded the Western Xia dynasty (1038–1227) in northwestern China, which was eventually overthrown by the Mongols. The Tangut script, which was devised in 1036, was widely used in printed books and on monumental inscriptions during the Western Xia period, as well as during the Yuan dynasty (1271–1368), but the language became extinct sometime during the Ming dynasty (1368–1644). The latest known examples of Tangut writing are Buddhist inscriptions dated 1502 on two dharani pillars from a temple in Baoding, Hebei. By the Qing dynasty (1636–1912) all knowledge of the Tangut language and script had been lost, and no examples or descriptions of the Tangut script had been preserved in any surviving Chinese books from the Song, Yuan or Ming dynasties. It was not until the 19th century that the Tangut language and script were rediscovered.
