Bulgar language

(Not to be confused with Bulgarian language.) Bulgar (also spelled Bolğar, Bulghar) is an extinct language which was spoken by the Bulgars. The name is derived from the Bulgars, a tribal association which established the Bulgar state, known as Old Great Bulgaria in the mid-7th century, giving rise to the Danubian Bulgaria by the 680s. While the language was extinct in Danubian Bulgaria (in favour of the Slavic Bulgarian language), it persisted in Volga Bulgaria, eventually giving rise to the modern Chuvash language.
