Champa is not one kingdom ruled from one court but a string of river-mouth plains, each behind a port and each with a highland valley at its back, that obey whichever of them is strongest.
The older books (Maspero) speak of five federated principalities, Indrapura, Amaravati, Vijaya, Kauthara and Panduranga; the French Wikipedia, following Vickery, calls that model obsolete and has a kingdom centred on Vijaya, split into provinces under central authority, with Panduranga (capital Virapura) the most autonomous. The king on 1 January 1200 is Suryavarmadeva, who was the Khmer king's Cham protege in 1190, turned on him, and has held the coast since about 1192. He is at war with Jayavarman VII.
No source places an army, a court or a battle on or near 1 January 1200.

English, French and Chinese Wikipedia; the Cham stelae and the Khmer stele of 1191 as reported there. Maspero, Coedes and Vickery were not opened.
What the realm holds
- Vijaya (Chà Bàn) on the Côn river plain with its port Thị Nại, the likely seat
- Amaravati: Simhapura (Trà Kiệu), Indrapura (Đồng Dương) and the My Son valley, the port at the Thu Bồn mouth, the gold of Bồng Miêu
- The Quảng Ngãi plain with the earth citadel of Châu Sa (Co Luy), the salt of Sa Huỳnh
- The Hue plain (Châu Ô and Châu Lý) behind the Hai Van spur, the northern edge: Thanh Lôi and Liễu Cốc
- Phu Yen (the Da Rang mouth), Kauthara (Po Nagar at Nha Trang, Cam Ranh bay), Panduranga (Phan Rang, Hòa Lai, Phan Rí)
- Tribute, gifts and marriage ties, not tax, with the hill peoples who bring eaglewood, ivory, cinnamon, wax and horn
- Temple lands and servants of Po Nagar and Bhadresvara (My Son), recorded in the steles
How it was acquired
Three readings of 1190 to 1192 are in print. (1) The Maspero and Coedes line, as the Chinese Wikipedia has it: the Khmer take Vijaya in 1190 and carry off Jaya Indravarman IV, set a Khmer-backed prince 'In' on a throne at Panduranga, and a Cham prince Suryajayavarman is enthroned at Vijaya in 1191, beats Panduranga in a civil war, unifies the country and declares independence. (2) The line in the MSA brief: the Cham prince Vidyanandana, raised at Angkor, is put in the old king's place, turns on his patron and has the old king killed in 1191 or 1192.
(3) The French Wikipedia's chronology: Vidyanandana first at Panduranga from 1190 or 1192, then over the whole country, with Jaya Indravarman IV briefly restored 1191 to 1192. All three end with one king, Vidyanandana or Suryavarmadeva, in sole rule.
Allies and rivals
Khmer: Jayavarman VII, his patron turned enemy. The English Wikipedia dates Jayavarman's campaigns against Champa 1190, 1192, 1194-1195 and from 1198 on; the campaign board has 1193 and 1194. We use the English list. Dai Viet: the campaign board says the Ly court recognised him in 1199 (unverified). Song: Jaya Indravarman IV sent tribute to China and to Dai Viet and tried to buy horses (English Wikipedia); we know of no Cham embassy to the Song in the 1190s.
The uncle On Dhanapatigrama, a Cham prince whose place on 1 January is not known (see his record). The hill peoples: courted by gifts and marriage (board), never taxed.
The realm that morning
Suryavarmadeva is king, most likely at Vijaya. The war with Angkor is in a stretch (from 1198 on in the English Wikipedia) that no battle is dated to, so on this morning the Khmer may be in the field or may not; the highland road in (An Khe to the Con, the Se San, the Srepok) is where an army would come. The yuvaraja On Dhanapatigrama is somewhere not known to me, at Angkor or in the south. Building goes on: the tall towers of Dương Long and the twin towers of Thap Doi belong to the late twelfth or early thirteenth century, so on 1 January 1200 they are new or still going up.
Wealth
Trade is the wealth: eaglewood, cinnamon, ivory, rhinoceros horn, cardamom, beeswax and captives from the hills; gold from Bồng Miêu; salt from Sa Huỳnh and Cà Ná; rice on the plains; kiln wares from Gò Sành (the wares are mostly of the thirteenth century, so a kiln at work in 1200 is inference). The ports are Thi Nai, the Thu Bon mouth, the Da Rang mouth, the Dinh mouths, Cam Ranh and Phan Ri.
Military
A war fleet is attested under Jaya Indravarman IV (the English Wikipedia: he built a naval squadron after failing to buy horses in China; Vickery doubts the sack of Angkor in 1177). Earth-and-brick citadels at Cha Ban, Simhapura, Chau Sa and Thanh Loi. The Chinese Wikipedia has a Fujian man teaching Cham troops cavalry archery in 1171. We give no numbers.
Threats
- A Khmer army by the An Khe pass and the Con valley, or by the Se San and the Ba
- A Khmer fleet into Thi Nai
- The uncle On Dhanapatigrama and any Cham lords who sided with the old king
- Panduranga going its own way
- The hill peoples closing the trade roads
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.
- 1203 (the Cham stelae and the Vietnamese annal; month not given for the fall)The yuvaraja On Dhanapatigrama, with a Khmer army, beats Suryavarmadeva and takes Vijaya; the king flees north by sea and reaches Cua Lo in August 1203, is not given refuge, and vanishes.Depends on: The Khmer keep their forward base and the uncle stays loyal to Angkor. Stopped by: A Khmer defeat in the highlands or a Cham reconciliation.
- 1203 to 1220 or 1226Champa is governed as a Khmer province; building at My Son and Po Nagar stops for a generation.Depends on: Angkor holds the coast. Stopped by: Jayavarman VII's death or a rising.
- 1220 or 1226 (the inscriptions disagree)Jaya Paramesvaravarman II, a Cham prince raised at Angkor, restores a Cham kingdom; the Khmer withdraw.Depends on: The Khmer empire pulls back from its outer holdings. Stopped by: A Khmer relief force.
- 1306Jaya Simhavarman III gives Chau O and Chau Ly (the Hue plain) for a Viet princess: the frontier moves to the Hai Van.Depends on: A marriage treaty. Stopped by: A war or a refusal.
Places of note
- Vijaya (Cha Ban): The likely seat
- Thi Nai: The harbour of Vijaya
- An Khe pass: The step from the Con valley to the Bahnar plateau
Where the sources disagree
- Board 'Champa' blurb: Khmer armies 'came against him in 1193 and 1194 and were beaten'. The English Wikipedia (Champa) gives 1190, 1192, 1194-1195 and 1198-1203; we use that list and make no claim of Cham victories.
- Board: 'recognised by the Ly court in 1199, which buys a quiet frontier': unverified; no source we could open mentions it.
- Board: 'sent home in 1190 with the army that broke his own country; killed both the captive king and the usurper who followed him': sources differ (see acquired); the MSA brief says he killed the old king in 1191 or 1192.
- The campaign board entry says he holds Vijaya on 1 January 1200: plausible (the 1203 flight is from Vijaya) but not shown; the French Wikipedia has him first at Panduranga.
- The campaign board's 'federation of five plains' is the older model; the French Wikipedia, after Vickery, calls it obsolete.
- Saka dating: 1 January 1200 falls in Saka 1121 (the year that began in the spring of 1199).
Evidence: The Cham and Khmer steles are the best evidence, but the years 1190 to 1203 reach me only through Wikipedia articles that disagree with each other; Maspero, Coedes and Vickery could not be opened.
"The campaign board" is OMNIA's working map. These notes record where its earlier claims were checked against the sources.
On the map: Coastal plains drawn as unions of modern districts; the old plains had no such edges. The highland valleys behind each plain belong to the hill peoples and are drawn as their own records.
