Note 251 — Chapter XVI · The Kara-Khānides, or Uïghūrs
Reading edition
The name Uïghūr is first found in Mohammedan histories at the beginning of the thirteenth century. Previously to this they seem to have been known by the name of Taghazghaz, which is doubtless a corruption. Cf. Tarikh-i-Rashidi, or, History of the Moghuls of Central Asia, by Ney Elias and E. Denison Ross, p. 94 of Introduction.
