The northern end of the plateau: the Sedang of Đắk Glei, Kon Plông, Ngọc Hồi and Đắk Tô, round the headwaters of the Sê San and the Thu Bồn tributaries.
They sell to whichever side is buying; anyone marching from Angkor to Vijaya overland comes through this basin (board). We found no source for a Cham or Khmer post here. The group names are those of the nineteenth and twentieth century; the Chinese and Cham sources of the time use general labels. We use the later name only to say which people the ground is for, and we read their society backwards from later ethnography: villages with headmen and elders, shifting fields, no kings and no towns.
Who holds it
- Title
- Village headmen and councils of elders; no overall chief is known for 1200
- Confidence
- low
Later ethnography read backwards; Chinese trade lists and Cham inscriptions that name hill goods (board)
Overlord
None that we can show.
How things stand that morning
Governing itself under village headmen; the lowland courts trade with it and claim it in name; not pinned further.
Wealth
Eaglewood, bark, wax, iron.
Military
Village fighters; no numbers.
Places of note
- Dak To: Sedang country
Where the sources disagree
Evidence: Chinese trade lists, Cham inscriptions that name hill goods, and ethnography written six centuries later (board); no dated event for 1200.
On the map: A union of modern districts standing for the people's country; there was no border, and the groups overlapped and traded across any line we draw.
