Bactrian language
Bactria came under formal Hephthalite rule from that time. Taxes were levied by the Hephthalites over the local population: a contract in the Bactrian language from the archive of the Kingdom of Rob, has been found, which mentions taxes from the Hephthalites, requiring the sale of land in order to pay these taxes. It is dated to 483/484 CE.
