Magnates and their honours · The Khmer empire of Jayavarman VII · as at first light, 1 January 1200

Lavo

Lavapura had its own silver coins in the 7th or 8th century, an old Mon population, and Chinese embassies of its own (Luohu) in 1115 and 1155, and again in 1289 to 1299.

The Khmer put their name on it under Suryavarman I and the Preah Khan stele of 1191 lists Lavodayapura first among the western towns that received Jayavarman VII's Buddha image. The Bayon-style Phra Prang Sam Yot, begun about 1200 or in the early 13th century, is the clearest Khmer building programme on the plain. Yet Wyatt, reading sixteen dated inscriptions of 1168 to 1219, found no Angkorian administration, and the Zhufan zhi (1225), which lists Luohu as a dependency of Zhenla, is doubted.

The safe reading for the game: a Khmer seat of real weight, answering to Angkor in titles, gifts and religion, doing as much as it pleases in practice, with a lord no source names for 1200. It controls the rice of the lower river, the road to the Gulf and the copper and iron of Khao Wong Prachan.

Who he is

Title
Lord (or Khmer prince) of Lavodayapura
Since
not known
Born
not known
Family
English Wikipedia (Lavo Kingdom) reports, without a source we could read, that Jayavarman VII appointed a kinsman, Narapatindravarman (spelt Narupatidnavarman there), to govern Lavapura in 1181, and that Coedes recorded a son of the king as 'prince of Lavo'. Songsiri reads such titles as kinship between ruling houses, not administration. A Mon-Tai clan from Chaliang is said to have held Lopburi (same article).
Confidence
low

English Wikipedia (Lavo Kingdom; Lopburi), after Wyatt, Baker and Pasuk, Songsiri. None of the names is dated to 1 January 1200.

Overlord

Angkor by title, at least from Suryavarman I; the strength of the tie in 1200 is argued (see summary).

What it holds

  • Lavodayapura with its moat and the Bayon-style towers going up (Phra Prang Sam Yot, Wat Phra Si Rattana Mahathat prang, San Phra Kan)
  • The Lopburi river plain and the Pa Sak mouth
  • The Khao Wong Prachan metal field (copper and iron) and its smelting mounds of Non Pa Wai and Nil Kham Haeng, worked since long before the Khmer
  • Boat stages on the Chao Phraya and Pa Sak

How it was acquired

By the Khmer from the early 11th century; the local line is older. Not dated.

Allies and rivals

Angkor; Suvarnapura and Chaliang (kin and neighbours); Haripunjaya to the north (northern chronicles tell of wars through the 12th century, all later and the Tai north researcher's ground); the Mon monasteries of the plain.

How things stand that morning

A seat under Khmer titles with Khmer building in progress; its lord is not known. The nearest dated Lopburi text is of 1213, thirteen years later: it is in Khmer, records a Buddha image of Candasvaratana and counts time in the Khmer manner, so it shows the habit of the place but nothing about the winter of 1199 to 1200.

Wealth

Rice, boat tolls, metal, salt and forest goods in transit.

Military

Moat and levies; no numbers.

Threats

  • The Tai chiefs of the upper plain
  • A weak Angkor after the old king

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.

  1. 1289 to 1299Lavo sends its own embassies to the Yuan court (Baker and Pasuk count four, English Wikipedia's table five); it has broken from Angkor.Depends on: A Khmer court too weak to keep its seats. Stopped by: A strong Angkor after Indravarman II.
  2. 1351Ramathibodi (U Thong) founds Ayutthaya on the river island and folds Lavo and Suphan Buri into one kingdom.Depends on: A new house on the lower river. Stopped by: No Ayutthaya.

Places of note

  • Lavo (Lopburi): The moated town.
  • Phra Prang Sam Yot: Bayon-style towers, begun about 1200 or later.
  • Khao Wong Prachan: Copper and iron field.

Where the sources disagree

  • The campaign board entry lavo-lopburi (secure): 'a governor answering to Angkor'. Wyatt found no sign of Angkorian administration; we write a Khmer seat with weight of its own.
  • The campaign board entry phra-prang-sam-yot: 'Bayon manner under Jayavarman VII' is style dating; English Wikipedia gives groundbreaking c. 1200 and the early 13th century, so on 1 January 1200 it is at most begun.
  • English Wikipedia (Lavo Kingdom) after Wyatt: sixteen dated inscriptions of 1168-1219 from Lopburi and the western plain show no sign of Angkorian political or administrative power ('not conclusive'); Baker and Pasuk: the plain has none of the temple-endowment inscriptions typical of Angkorian provinces. The Preah Khan stele of 1191 lists six western towns among the 23 that received Jayabuddhamahanatha images.

Evidence: Monuments, inscriptions counted by Wyatt, Chinese embassies; no lord named.

"The campaign board" is OMNIA's working map. These notes record where its earlier claims were checked against the sources.

On the map: A block round the town and the Pa Sak mouth; the real reach is by boat and road.
