What it is

An adaptation of the Greek alphabet, with a new letter (sho) for the sh sound, to write the Bactrian language. Kanishka replaced Greek with Bactrian in his administration, as a stone inscription found in 1993 recounts.

The dating of Kanishka's reign is one of the most debated in ancient Asian history: 127 and 78 AD are proposed as its start. This entry follows the most widespread chronology (c. 127) with a wide margin.

What it led to

  • the official language of the Kushan Empire and the Hephthalites
  • Tokharistan documents revealing administration in Kushan and later times
  • the Rabatak inscription (deciphered by Nicholas Sims-Williams and Joe Cribb) as a source for Kushan history
