Two river valleys east of the Phi Pan Nam ridges: the Yom, with Phrae (Wiang Kosai) and Muang Song above it, and the Nan, with Pua above and the narrows at Wiang Sa below, and the brine wells of Bo Kluea in the hills of the upper Nan.
The wells are the only salt for a long way in the interior and are the wealth of the region: whoever held them taxed everyone's cooking. Both valleys have chronicles (the Phrae chronicle; the Nan Chronicle) that begin their ruling lines too far back or too late to use for 1200: Nan's starts at Pua in the thirteenth century, Phrae's with a ninth-century or eleventh-century foundation that nothing dated supports. So the realm is the two valleys, the wells and the roads; the chiefs are not named.
A muang here means one rice plain with a stockade or a moated town at its head, and loyalty to a person.
Who rules
- Title
- Chiefs (chao) of Phrae (Wiang Kosai) on the Yom and of the valley of Pua on the upper Nan; the salt-well families of Bo Kluea
- Since
- not known
- Born
- not known
- Family
- No ruler is named for either valley on 1 January 1200. The Nan Chronicle (compiled in the Bangkok period) starts its line at Pua with Khun Fong and Phukha (Phukha 1269 to 1337 in the Wikipedia infobox); the Phrae chronicle gives a foundation of 828 in the English Wikipedia article, unsourced.

What the realm holds
- Phrae (Wiang Kosai), a moated town on the middle Yom, with the relic hill of Phra That Cho Hae behind it
- Muang Song and the upper Yom on the road toward the Ing and the Mekong
- The rice plain of the upper Nan round Pua; the narrows of the Nan at Wiang Sa below
- The brine wells of Bo Kluea (the sources reach them only from the fourteenth century)
- The lac and forest-produce villages of the Nan uplands, which the Chinese trade lists name without naming where it was gathered
How it was acquired
Not known; both valleys are old rice country and the chronicle lines are later than the facts.
Allies and rivals
Phayao over the ridge to the north-west (its chronicle takes Pua in 1263); Haripunjaya and Khelang Nakhon beyond the Phi Pan Nam; the Chaliang and Sukhothai plain to the south; the Lao muang across the hills to the east (Muang Sua, which the Nan Chronicle ties to Khun Nun, a son of Phukha). None of these dealings is dated before 1263.
The realm that morning
Two valley principalities and a salt district with no recorded lord or event on 1 January 1200. Phrae is a moated town with a relic hill; the upper Nan is settled rice country with no attested muang seat (the chronicle's Pua line starts in the 1260s to 1280s); the Bo Kluea wells are worked by the fourteenth century at least and probably earlier.
Wealth
Salt boiled down from the brine of Bo Kluea and sold by pack and boat to the Yom, the Mekong and the Lao muang; rice of the two valleys; stick lac, wax and forest produce from the hills; teak is cut for local use only.
Military
Nothing recorded. The moated town of Phrae and the hill refuges.
Threats
- Phayao's rise: Ngammueang takes Pua in 1263 in the chronicle
- The Sukhothai rulers' push north up the Yom (after 1238 or about 1243)
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.
- 1263Ngammueang of Phayao seizes Pua, the Nan capital, and places his son there (Nan Chronicle and Phayao tradition).Depends on: A strong Phayao under Ngammueang (1258 to about 1318). Stopped by: A Nan-Phrae alliance.
- 1269 to 1337 (Wikipedia infobox)Phukha, the Nan Chronicle's founder of the line; his son Khun Fong founds Pua for the Kao people and another son, Khun Nun, rules Luang Prabang.Depends on: The Nan Chronicle being right on the order. Stopped by: The chronicle's late compilation making the story a later invention.
- 1292 (disputed)The Ram Khamhaeng stele, whose authenticity has been disputed since 1987, is said (as we recall it, not re-read) to name Phrae and Nan among the places in a Sukhothai ruler's reach.Depends on: The stele's text being genuine of 1292. Stopped by: The stele being a later work.
Places of note
- Phrae (Wiang Kosai): moated town on the Yom
- Pua: rice plain of the upper Nan
- Bo Kluea: the salt wells
Where the sources disagree
- Board (nan-valley-pua): "the Nan chronicle begins its ruling line at Pua under Phu Kha in the 1280s". English Wikipedia: Phukha 1269 to 1337, Pua founded 1282 (infobox), Pua taken 1263. The dates inside the chronicle tradition do not agree.
- Board (bo-kluea-salt): "the workings are old". The only dating we found puts the wells in use by the fourteenth century (Nan Kingdom article); earlier use is probable but not shown.
Evidence: Chronicles only, compiled in the Bangkok period (the Nan Chronicle) or of unstated date (Phrae); no inscription, Chinese notice or excavation we could reach dates the valleys' lords in 1200. The valleys and the salt are certain; the states over them are not.
On the map: Drawn on the valley floors and the salt district; the hills between are shown as the Kha peoples' country.
