The Lao kingdom of the middle Mekong, joined under one crown by an exile's son raised at the Khmer court, which fought Burma to a standstill, lost a king without a trace in a Cambodian jungle, split into rival thrones, and fell at last to a Siamese army.

Fa Ngum's coronationSuccession crisis
Raised in exile at the Khmer court of Angkor and given an army by his father-in-law the Cambodian king, Fa Ngum fought and negotiated his way up the Mekong, winning most of his rivals' submission through a shared claim of descent from a common ancestor rather than by conquest, before taking Wiangchan by a feigned retreat and being crowned king - joining Luang Prabang and Wiangchan under one throne for the first time.

Jai Jett'a returns from Chiengmai with Buddha imagesSuccession crisis
Crowned Maharaja of Chiengmai shortly after his father's death, Jai Jett'a chose to return to Luang Prabang instead to fight his own younger brother for their father's throne, carrying with him the Emerald Buddha, the crystal Buddha of Lamp'un and other images sacred to Chiengmai - none of which he ever returned. Chiengmai's nobles, finding the Chiangmai throne he had abandoned, summoned a rival prince to fill it instead.

Jai Jett'a besieges P'itsanulokSiege
Invited by a disaffected Siamese official to intervene against a pro-Burmese governor, Jai Jett'a marched a large army to the Siamese border town of P'itsanulok and laid siege to it, briefly threatening to draw Lan Xang into a direct contest for influence over Siam's own northern provinces before a relieving Burmese force compelled his retreat.

Jai Jett'a lost in the Cambodian jungleCatastrophe
While campaigning in Cambodia, Jai Jett'a became separated from his forces in the jungle and was never seen again, leaving no adult heir; an infant son was proclaimed king under a regent, a succession too fragile to resist the pressure that followed from Burma.

Burma installs Jai Jett'a's brother as vassal kingSuccession crisis
The Burmese king demanded the regent's abdication in favor of one of Jai Jett'a's own brothers, a prisoner in Burma since an earlier invasion; when the regent refused, a Burmese army invaded, captured the infant king's guardian, and placed the brother on the Wiengchan throne as a tributary ruler - the furthest extent of Burmese power over the kingdom.

One crown dividedTreaty
Rather than fight his cousin's Siamese-backed army for control of Wiengchan, Prince Kingkisarat of Luang Prabang agreed to a treaty splitting the old kingdom outright, one cousin keeping Luang Prabang and the other Wiengchan as separate thrones; a third kingdom, Champasak, already stood apart downriver by the time Siam next intervened in Lao affairs in the 1770s, though the source gives no account of when or how it separated.

A Siamese army of twenty thousand, joined by the rival prince of Luang Prabang, besieged and after several months captured Wiengchan, terrorizing the countryside with boatloads of severed heads offered for sale outside a neighboring town and stripping the captured capital of everything of value, the Emerald Buddha included. Luang Prabang and Wiengchan both became Siamese dependencies from that year.

Brothers since Borom
formationDrafted from Cowing, The Indianized States of Southeast Asia (1968)
Fa Ngum was born in 1316 the son of a Lao prince exiled for a fault
the chronicles remember only as a fit of temper - Phi Fa, "Spirit of
Heaven," a name his own father gave him in bitter irony after Phi
Fa's taste for women reached into the royal harem itself and got him
driven out before he ever ruled. Father and infant son found refuge
at the Khmer court of Angkor, where a Cambodian king raised the boy,
married him to his own daughter at sixteen, and, at some point between
1340 and 1350, gave him an army to go reclaim the kingdom of his
grandfathers.
A conquest paid for in kinship
The Lao chronicle Nithan Khun Borom describes Fa Ngum's advance up the
Mekong through Bassac, Khammuan and Tran-ninh, negotiating a border
with Dai Viet along the way, before descending on Muang Chawa - the
future Luang Prabang - where he was proclaimed king. What made the
conquest possible, the same chronicle insists, was less force than a
shared claim of descent every Tai-speaking ruler in his path
recognized: the Tran-ninh envoys called him brother through their
common ancestor Khun Borom, a Tai chief of the Sip Song Phan Na made
the same appeal rather than fight him, and even the king of Ayutthaya,
moving to check Fa Ngum's advance onto the Khorat plateau, chose to
offer territory and a royal marriage instead of battle, reminding him
they were "brothers since Borom." Only at Wiangchan did Fa Ngum resort
to force outright - and even there by trick rather than storm, luring
the defenders out to gather a feigned retreat's abandoned gold and
silver arrows before turning on them in the open.

A coronation, and a Buddha that gave the capital its name
Fa Ngum's own solemn coronation, which the sources place in 1353,
marks the founding of the kingdom that would come to be called Lan
Chang (Lan Xang). It joined Luang Prabang and Wiangchan under one
crown for the first time, at the expense of a Khmer garrison presence
on the upper Mekong that had held the territory since Jayavarman VII's
own reign a century and a half before. Fa Ngum did not forget the
court that had raised him: shortly after his accession he sent his old
religious tutor, Maha Pasaman, back to Angkor with a mission of monks
and artisans, who returned with sacred texts and a revered image, the
Phra Bang - the statue that would eventually give Luang Prabang its
own name, and the clearest sign that the kingdom Fa Ngum built on the
upper Mekong owed its script, its Buddhism and its court culture to
the same Khmer world his own family had once fled to as exiles.

The images that never went back
peakDrafted from Wood, A History of Siam (1926)
Jai Jett'a came to power by leaving a throne rather than seizing one.
Crowned Maharaja of Chiengmai shortly after the death of that kingdom's
own king in 1547, he chose within two years to abandon it and return to
Luang Prabang to fight his younger brother, who had claimed their father's
Lao throne on his sudden death. He took with him some of Chiengmai's most
sacred possessions: the Emerald Buddha, the crystal Buddha of Lamp'un, and
other images that had been kept in that city for generations. Only one of
them - a lesser image called the P'rasingh - was ever returned. Chiengmai's
own nobles, finding their throne effectively vacated, simply summoned a
rival prince to fill it.
A new capital on the river
Some time in the years that followed, Jai Jett'a moved his own capital
from Luang Prabang downriver to Wiengchan, a site he named Sri
Satanakonahut - what later ages would know as Vientiane. The Emerald
Buddha moved with him, and would stay in his new capital for more than
two centuries.

A princess sent, and a princess sent back
The new king's ambitions extended into marriage diplomacy with Siam
itself. He asked King Chakrap'at of Ayut'ia for the hand of Princess T'ep
Krasatri, daughter of the warrior queen Suriyot'ai; when the princess fell
ill before her journey, the Siamese king sent a different daughter in her
place. Jai Jett'a was, in the words of the chronicler who later recorded
it, a man whose "taste in collecting Princesses seems to have been equal
to his discrimination in amassing other people's images of Buddha" - he
sent the substitute back at once, with a blunt message that he would
accept T'ep Krasatri and no one else. In 1564 the princess finally set out
for Wiengchan, only to be intercepted en route by a Burmese force acting
on intelligence from a rival Siamese governor and carried off to Burma
instead - a diversion that left the marriage forever unconsummated, and
left Jai Jett'a and that governor enemies from that day forward.

The siege of P'itsanulok
peakDrafted from Wood, A History of Siam (1926)
Jai Jett'a spent most of his reign fighting off Burma rather than fighting
for advantage elsewhere, but one episode shows how far his own ambitions
reached when the opportunity arose. A Siamese governor, out of favor with
the pro-Burmese faction controlling the regency at Ayut'ia, invited Jai
Jett'a to intervene against the border town of P'itsanulok, then held by
the very official who had helped intercept Princess T'ep Krasatri two
years before. Jai Jett'a needed no second invitation. At the end of 1566
he marched a large army to the town and laid siege to it, while a Siamese
prince who marched north ostensibly to relieve the town in fact intended
to hand it over to the Lao king instead. The plot failed - the townspeople
refused the prince admittance - and a Burmese relief force arrived before
Wiengchan's army could take the walls, forcing Jai Jett'a to withdraw.

A kingdom that kept surviving invasion by disappearing into the jungle
The pattern held throughout his reign: when Burmese armies invaded
Wiengchan itself, in 1563-64 and again in 1569-70, Jai Jett'a did not try
to hold his capital against them. He abandoned it and withdrew into the
jungle with most of his own population, waiting out Burmese armies that
suffered, each time, from famine and disease before they retired. It was
not a glamorous strategy, but it worked twice running - a kingdom too
thinly held to be occupied for long, and too elusive to be permanently
broken by any single campaign.
Lost in the jungle
contractionDrafted from Wood, A History of Siam (1926)
The strategy that had twice saved Wiengchan from Burmese occupation could
not save the king who relied on it. In 1571, campaigning in Cambodia, Jai
Jett'a became separated from his own army in the jungle and was never
found again - no body, no captor, no clear account of what became of him,
only a king who simply stopped appearing in the record. One later
chronicler, unable to resist the irony, called it a fitting judgment on a
man who had once carried off Chiengmai's most sacred images and never
returned them.

An infant king, and a regency too weak to hold
With no adult heir in the capital, an infant son of Jai Jett'a was
proclaimed king, governed in practice by a regent. It was exactly the kind
of succession a hostile neighbor could exploit, and Burma did not wait
long to try.
A brother's borrowed crown
contractionDrafted from Wood, A History of Siam (1926)
Burma's king demanded that the infant's regent abdicate in favor of one
of Jai Jett'a's own brothers - a man who had spent years as a prisoner in
Burma since an earlier invasion of Wiengchan, and who could therefore be
relied on to rule as a compliant vassal. The regent refused. In 1574 a
Burmese army invaded, captured the guardian who had been protecting the
young king, and placed Jai Jett'a's brother on the Wiengchan throne under
Burmese supervision - the furthest reach Burmese power would ever achieve
over the Lao kingdom, and a striking reversal for a dynasty that only a
few years before had been strong enough to besiege a Siamese border town
on its own initiative.
Two decades, then a throw of the yoke
Vassalage did not last forever. In 1595, after twenty-one years as a
Burmese tributary, Wiengchan renounced the arrangement and reasserted its
own independence - one of the last of the mainland kingdoms Burma had
subdued in its sixteenth-century expansion to shake the yoke off
entirely. The kingdom that had once survived by vanishing into its own
jungle proved just as capable of waiting out an occupying overlordship as
it had been at waiting out an invading army.
One crown divided
endDrafted from Wood, A History of Siam (1926)
Independence recovered in 1595 did not bring stability. For more
than a century afterward, rival princes contested the Wiangchan
throne with little the neighboring kingdoms troubled to record in
detail - until, by 1699, the dispute had split the kingdom outright.
Prince Chao Ong Wiet had set himself up as king at Wiangchan; his
cousin, Prince Kingkisarat, had meanwhile seized Luang Prabang and
now prepared to reunite the two by force, marching against his rival's
capital.
A princess offered, an army that never fought
Ong Wiet, facing a cousin's army he could not match alone, appealed
to Siam for help and offered his own daughter's hand as the price of
alliance. Ayutthaya's king sent a relief force at once - but the
campaign never came to battle. Kingkisarat, weighing his own chances
against the combined strength of Wiangchan and its new Siamese ally,
chose negotiation instead: a treaty dividing the old kingdom of Lan
Xang between the two cousins outright, one to hold Luang Prabang and
the other Wiangchan, each an independent throne rather than a single
crown contested between two claimants. The promised princess went on
to Ayutthaya regardless, where she was given in marriage to the
Siamese king's own heir.
A third throne, already standing apart
By the time Siam next intervened in Lao affairs, in the 1770s, a
third kingdom existed on the middle Mekong as well: Champasak, ruled
by a Prince Chao O as an independent principality in its own right,
far enough downriver that Wood's own account treats its separation
from the old body of Lan Xang as an accomplished fact rather than a
recent event needing explanation, and how or when it broke away is
left unstated. What is certain is that
the single kingdom Fa Ngum had joined by conquest in 1353, and that
Jai Jett'a had governed as one throne two centuries later, had by the
early eighteenth century become three separate courts - Luang
Prabang, Wiangchan and Champasak - each answering for itself, and
each, within a century, a tributary of one or another of its
stronger neighbors rather than of any single Lao crown.

Heads for sale outside P'ak'o
endDrafted from Wood, A History of Siam (1926)
Two centuries after Jai Jett'a's reign, a chain of events set off by a
Siamese campaign against Champasak brought a reckoning to Wiengchan
itself. A Wiengchan noble named P'ra Woh, who had rebelled against Prince
Bun San, ruler of Wiengchan, fled south to Champasak territory and
submitted formally to the victorious Siamese army when it arrived there.
As soon as the Siamese withdrew, Bun San's forces caught P'ra Woh and cut
off his head. King Taksin of Siam took the killing as an act of war
against himself, and raised an army of twenty thousand men to invade
Wiengchan in response, joined by the rival Prince of Luang Prabang, who
saw in Siam's campaign a chance to settle old scores of his own.
A siege months in the taking
Wiengchan held out for several months. During the siege of the nearby
town of P'ak'o, the besieging Siamese sent women out to sell boatloads of
severed heads outside the walls - a calculated act of terror the source
that records it compares, without much exaggeration, to Burmese methods
in their own invasions of the kingdom two centuries before. When
Wiengchan finally fell, the Siamese stripped it of everything of value
they could carry.
The Buddha that finally left for good
Among the plunder taken from the captured capital was the Emerald Buddha
itself - the same image Jai Jett'a had carried off from Chiengmai more
than two hundred years earlier, and which had stood in Wiengchan ever
since. It went to Bangkok, where it remains. From 1779 until the French
protectorate arrived in 1893, both Luang Prabang and Wiengchan stood as
dependencies of Siam - a kingdom that had spent two centuries acquiring
sacred images and vassal thrones by turns finally reduced, in a single
campaign, to keeping neither.
