Ngoenyang in 1200, Ngoenyang

The senior Tai muang of the Mekong bend and the house from which Mangrai comes.

The chronicles put its seat near Doi Tung and the mouth of the Ruak; where exactly is disputed. English Wikipedia says Ngoenyang was most likely near Doi Tung and that Wiang Phang Kham, near Mae Sai, is argued to be the same city. The walled city of Chiang Saen is the work of a later age: English Wikipedia says it was founded in 1329 by Saenphu, a grandson of Mangrai, with a moat on three sides, the Mekong on the fourth and an earth wall behind the ditch; the campaign board says brick walls in 1328.

The same article says Ngoenyang was probably the first major city in the area, on a trade route to Yunnan, and that its name is still used interchangeably with Chiang Saen. On 1 January 1200 the seat is a stockade of earth, timber and ditch with rice land at its foot, the Mekong landing below it and hill villages round it. There is no brick wall, no mint and no inscription, and the lord is known only by chronicle names that disagree.

English Wikipedia (Ngoenyang, Chiang Saen, Mangrai).

Lord in 1200

The phaya of Ngoenyang (name not known).

What the town holds

The stockaded seat and its rice land on the Chiang Saen plain
The Mekong landing and the boats of the river
The roads to Sop Ruak, Mae Sai and the Kok

How it was acquired

Not known; the chronicle line from the hero Lao Chong is legend in its early part.

Allies and rivals

Phayao (cadet line or friend), Fang (cadet seat), the Lawa and Shan chiefs across the Ruak and the Sai (Burma), Chiang Rung up the Mekong, Haripunjaya over the passes. No dated war or treaty in 1200.

How things stand that morning

A Tai chief in a stockaded seat, at peace so far as any source shows. The chronicle wars of the 1170s to 1190s belong to the legend cycle and are not used as events.

Wealth

Rice, crossing tolls on the Mekong and the Sai, captives from raids, hill produce.

Military

Stockade, ditch and the levy of the valleys; no numbers.

Threats

Quarrels among the cadet lines (undated)
Hill raiding across the Ruak and the Sai

Council

Not known; the phaya and his kin.

Communities

Tai, with Lawa and Shan neighbours.

Militia

The levy of the valleys; no numbers.

Walls and castle

Stockade, earth bank and ditch; the moat and earth wall of the city founded in 1329 are later.

Trade and crafts

Rice, river tolls, captives and hill produce.

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.

1329 (the campaign board: 1328)Saenphu founds the walled city of Chiang Saen, with a moat and an earth wall (English Wikipedia).Depends on: The chronicle sequence being right. Stopped by: Lan Na losing the Mekong bend.
1259 or 1261; 1262Mangrai succeeds his father at Ngoenyang and founds Chiang Rai on the Kok bend.Depends on: The chronicle line being right. Stopped by: A rival cadet line taking the seat.

Places of note

Doi Tung: relic hill above the plain
Sop Ruak: mouth of the Ruak

Where the sources disagree

Board (ngoenyang-chiang-saen): "Chiang Saen's brick walls go up in 1328". The English Wikipedia article on Chiang Saen gives 1329 for the founding, describes a moat and an earth wall and does not mention brick. Either way it is later than 1200.
The identification of Ngoenyang with the Chiang Saen site is disputed (Wiang Phang Kham near Mae Sai is the rival site). The point is drawn on Chiang Saen with that caveat.

Evidence: Chronicles only, all later than 1200 by three to seven centuries (Chiang Mai Chronicle, Chronicle of Chiang Saen, Yonok Chronicle); no inscription of Ngoenyang is known to me.

On the map: Near land by the tierra; the seat is a point on the later city.

Primary sources for Ngoenyang

Chronicles, registers, sagas and inscriptions written in or near 1200 that cover this entry. Each has its own page with editions, translations and where to read it.

The later Tai, Lao and Mon chronicles of the north, Ratanapanna (Jinakalamali); Bodhiramsi (Chamadevivamsa); anonymous monks and court scribes (the Chamadevivamsa about 1410; the Jinakalamali 1516 to 1528; the Chiang Mai Chronicle in its surviving form 1827; the Nithan Khun Borom 16th to 17th century). There is no text of 1200 for the Mon kingdom of Haripunjaya, the Tai muang of Ngoenyang (Chiang Saen), Chiang Rung, the Yom and Nan valleys, or the Lao middle Mekong.
