Note 349 — Chapter XXI · Chingiz Khān

Since the discovery and decipherment of the Orkon inscriptions it may be regarded as certain that the form Khitan, or Kidan, is but the Chinese transcription of the word Kitai, which is the name of a people, most probably of Manchurian origin, who, as is well known, ruled over Northern China during the tenth, eleventh, and twelfth centuries. It was borrowed by some of the tribes inhabiting those parts. Cf. note on p. 106 of vol. x. of Baron Rosen’s Zapiski, article by M. Barthold.
