Question about Tindanotae

regional? most of the men in the successor kingdoms whom documents, inscriptions, or histories identify as galatians never lived in any galatian settlement areas. i'd say its remains primarily a label for ethnicity, especially if we understand ethnicity as being primarily a factor of culture, and secondarily one of descent or physical appearance. region of origin has little do with it I think, at least in Ptolemaic Egypt. In the Seleukid empire, I think you may be right; I would be very surprised (if this could be found out) if there were no native Anatolians or Thracians soldiering as part of Galatian units.
