The stone evidence that this country was inside the Angkor orbit.
At Sukhothai: Wat Phra Phai Luang (late 12th century), Wat Si Sawai (late 12th or early 13th century, founded for Vishnu) and the Ta Pha Daeng shrine. At Chaliang, up the Yom: Wat Phra Si Ratana Mahathat, a Mahayana temple of the late 12th century with a prang in what is believed to be the Bayon style. What they prove is that Khmer builders and a Khmer taste reached the Yom valley.
They do not prove that Angkor governed it: Baker and Pasuk find no administrative trace of Angkorian authority west of the Khmer country (as the English page reports them), and the old story of a Khmer outpost freed by a Tai rising in 1238 is now doubted. Chaliang is named as a polity of its own, Cheng Liang, in the Song Shi for 1001. There is no Siam on this morning.
No monk, abbot or shrine-keeper is named for any of the shrines.

English Wikipedia (Sukhothai Historical Park): Wat Phra Phai Luang built in the late 12th century in the reign of Jayavarman VII (Gosling argues a Theravada foundation; little studied); Wat Si Sawai founded in the late 12th or early 13th century as a Hindu shrine for Vishnu, lower parts apparently Khmer; the Ta Pha Daeng shrine undated. English Wikipedia (Si Satchanalai Historical Park): Wat Phra Si Ratana Mahathat at Chaliang built as a Mahayana Buddhist temple in the late 12th century in the reign of Jayavarman VII, its prang believed originally Bayon in style.
Overlord
No governor is attested (see the Sukhothai record); Khom Sabat of the Lavo orbit is the figure the chronicle sources name.
What it holds
- Wat Phra Phai Luang, Wat Si Sawai and the Ta Pha Daeng shrine at Sukhothai
- Wat Phra Si Ratana Mahathat at Chaliang
- Endowments (not known)
How things stand that morning
Standing or in the last stage of building; dates are 'late 12th century' and cannot be pinned tighter.
Places of note
- Wat Phra Phai Luang: Khmer-style towers north of the old city (position uncertain by about 1 km).
- Wat Si Sawai: Three prangs inside the old city (placed at the town).
- Wat Phra Si Ratana Mahathat, Chaliang: Prang on the Yom bend (board placement).
Where the sources disagree
- The campaign board entry sukhothai-sukhodaya: 'a Khmer governor over it'. No Khmer governor is attested; the English Wikipedia page for the Sukhothai park says how far Angkorian authority reached is disputed.
- The Chaliang point (17.397, 99.805) is the campaign board's; the English Wikipedia coordinates for the Si Satchanalai park (17.5239, 99.7865) are for the Tai town 15 km to the north.
Evidence: Monuments dated by style on English Wikipedia; their patronage and the control of the towns are argued.
"The campaign board" is OMNIA's working map. These notes record where its earlier claims were checked against the sources.
On the map: Two discs; the hold of the Khmer orbit over these towns is argued, not shown.
