Tangut, also called Xixia, is the historical script used to write the Tangut language, spoken in what is now northwestern China. The script was created under the first emperor of Western Xia around 1036. Tangut texts include official, private, and religious writing, such as books, sutras, inscriptions, and manuscripts. The script continued under the Yuan and Ming dynasties and became obsolete by the end of the Ming dynasty. It was rediscovered in the late 19th century; the scholar N. A. Nevsky helped largely decipher it in the early 20th century. These dates describe the script, not the first surviving use of 𗬟.
