A wide upland basin between the Salween and the Mekong.
The Burmese chronicle claims it for Pagan and most historians do not believe it: Pagan's real reach stops at the Salween. The Tai town of Chiang Tung is founded here in 1243 by Mangrai's man on the chronicle, so on 1 January 1200 this is Wa and Lua country with Tai (Khun) settlers moving in. The Wa say they held it and were displaced about 1229; the Khun predecessor state Khemarattha is a tradition.
Mangrai himself is a Ngoenyang prince (Tai north) and not yet the king of anything.

English Wikipedia, Kengtung State: 'most of the early history ... is made up of myths and legends'; a predecessor Khemarattha said to be Tai Khun; Wa tradition says the Wa held the country and were displaced about 1229; the Tai town is founded about 1243 on the chronicle (Mangrai's delegate Mang Kun), or 1263 to 1267 on the Chinese records; the Kengtung Yazawin was written in Burmese in the nineteenth century.
Overlord
None shown. Pagan claims and the nearer valleys may pay tribute in some years; Dali claims on the Shweli side.
What it holds
- The basin floor and its villages
- The caravan and salt roads across the Salween and Mekong
How things stand that morning
A basin held by Lua, Wa and Khun communities; no ruler known; Pagan's claim is paper.
What the year holds
What happened next, if nothing in play changes it. Each event carries what it depends on and what would stop it.
- 1243 (Kengtung Yazawin) or 1263 to 1267 (Chinese records)A Tai town is founded at Kengtung from Mangrai's Lan Na.Depends on: Mangrai's rise in Ngoenyang (founds Chiang Rai 1262). Stopped by: No Lan Na.
Places of note
- Kengtung: Basin town site; Tai town founded later.
- Tachileik: Border river crossing; Mae Sai across the stream is on the Thai side (Khmer and Tai north records).
Where the sources disagree
- The campaign board entry kengtung-basin: 'The Tai town of Chiang Tung is founded here by Mangrai in 1243': that is the chronicle's date; the Chinese records give 1263 to 1267 for the first governor.
- Brief: Mae Sai and the Thai-side neighbours belong to the Tai north and Khmer records; this record stays on the Burmese side.
- Tachileik is drawn at 20.449, 99.879, the town on the Sai river; the gazetteer's Tachileik point (20.684, 99.851) is the township centre and lies about 26 km north of it.
Evidence: Chronicles of the nineteenth century and Chinese records of the 1260s and later.
"The campaign board" is OMNIA's working map. These notes record where its earlier claims were checked against the sources.
