Khazarian is thought to be a descendent of the Proto-Rovas script, which was used to the east of the Aral Sea between about the 1st and 6th centuries AD, when the tribes who were using it, including the Avars, Khazars and Ogurs, started to move into the Carpathian Basin. That process took until about 670 AD, after which the Proto-Rovas script became the Carpathian Basin Rovas and the Khazarian Rovas scripts. The Proto-Rovas script was perhaps a descendent of the Aramaic script.
The Khazarian Rovas script was used until the 10th century AD, and possibly until the 13th century. Inscriptions are mainly in Turkic languages, including Ogur, As-Alan and Common Turkic.
