Greco-Bactrian Kingdom
"Daxia", "Ta-Hsia", or "Ta-Hia" () was the name given in antiquity by the Han Chinese to Tukhara or Tokhara: the central part of Bactria. The name "Daxia" appears in Chinese from the 3rd century BC to designate a little-known kingdom located somewhere west of China. This was possibly a consequence of the first contacts between China and the Greco-Bactrian Kingdom.
