A seven-day kingSuccession crisis
Ramesuen, who had voluntarily abdicated to his uncle Borommaracha I eighteen years earlier, marched on Ayutthaya the moment Borommaracha's fifteen-year-old son Thong Lan took the throne, seized him, and had him executed after a reign of exactly seven days - restoring the founder's own bloodline to a throne it had given up without a fight.

King Intharacha I's two eldest sons met on a bridge inside Ayutthaya, each mounted on his own war elephant, to settle the succession by single combat between the animals; both were thrown and killed in the same encounter, leaving their younger brother to take the throne as Borommaracha II without another claimant left standing.

Ayutthaya's army brought home a working royal culture rather than plunder - consecration rites, palace language and legal formulae wholesale - and kept using a defeated rival's own court apparatus for longer than most dynasties last outright.

The first fallSiege
A vassalage imposed by force lasted only as long as the generation that had lost the battle. Fifteen years after his own father's defeat, Naresuan broke a subjection the previous reign had had no choice but to accept, and Ayutthaya did not lose its independence to an outside army again for nearly two centuries.

1688
The palace revolutionRevolt
A palace coup expelled a foreign garrison from inside the capital's own defences at the height of the closest relationship any court in the region had built with Europe, and the expulsion held for a century and a half - a reversal few port polities faced with a European garrison ever managed, and the clearest evidence that an inland agrarian capital was a fundamentally harder target than a coastal one.

The second fallSiege
A capital one of the largest cities in the world only decades earlier was left with no working government, no surviving legal code and no population large enough to defend it, and the war left almost nothing of its own to be reconstructed from.

What was carried north
formationDrafted from Phongpaichit, A History of Ayutthaya: Siam in the Early Modern World (2017)
Ayutthaya was founded in 1351 on an island where three rivers meet, about fifty
miles up the Chao Phraya from the Gulf. Eighty years later its army took Angkor,
and what it brought back was not treasure.

It brought the brahmans. The ritual specialists of the Khmer court, the
consecration rites, the Sanskritic royal titulature, the palace language, the
legal formulae — the working apparatus of Angkorian kingship went up the road to
Siam, and the Siamese court used it for four hundred years. The Bangkok dynasty
that followed was still using it in the twentieth century.
It was a whole court culture acquired by capturing the city that had it, and
Ayutthaya went on using it, without apparent embarrassment, for four centuries.
And the letters
Ayutthaya wrote in the Thai script, which is an adaptation of the Khmer script
made at Sukhothai in the late thirteenth century. So the titles taken from
Angkor in 1431 were written down in letters that had also come from Angkor, a
hundred and fifty years earlier and by a different route, through the
Sukhothai kingdom that had first adapted them.
The titulature and the alphabet it was written in had, by different roads and a
century and a half apart, the same origin.
The throne five times over
formationDrafted from Wood, A History of Siam (1926)
Ramathibodi I died in 1369 leaving a kingdom whose founder remains,
even in the Siamese chronicles' own telling, almost a blank: no
certain name before his royal title, no certain father, no account of
his life before he arrived at Ayutthaya through his marriage to a
local ruler's daughter. His son and heir, Ramesuen, proved unpopular
within a year - blamed for military incompetence in an earlier war
against Cambodia - and was persuaded by his own ministers to abdicate
in favour of his uncle, Borommaracha, governor of Suphanburi. The
handover was amicable enough that Ramesuen simply returned to his old
post as governor of Lopburi, and Borommaracha I spent the next
eighteen years completing what Ramathibodi had started: the conquest
of the rival Tai kingdom of Sukhothai to the north.
A seven-day king
Borommaracha I died in 1388 marching to relieve a governor under
attack, and the throne passed to his fifteen-year-old son, Thong Lan.
Ramesuen, still governor of Lopburi and still, by strict right, the
founder's own son, marched on Ayutthaya at once, seized his young
cousin, and had him put to death after a reign of exactly seven days
restoring himself to the throne he had voluntarily given up eighteen
years before. Five years later he led an army into Cambodia in
retaliation for a border raid, routed the Cambodian forces in the
field, and took the Khmer capital at Angkor Thom itself, installing a
Cambodian client king under a Siamese garrison and carrying off
ninety thousand prisoners - a full generation before the conquest that
would end Angkor's own independence for good.
Fourteen years of nothing recorded
Ramesuen died in 1395, and his own son, Ramracha, took the throne to
a reign the chronicles pass over almost entirely - fourteen years in
which, as Wood's own sources put it, "nothing whatever is recorded as
having occurred." It ended in 1408 when Ramracha quarrelled with his
chief minister; the minister fled to Suphanburi and appealed to its
governor, Nakhon In, a nephew of Borommaracha I, who marched on
Ayutthaya, forced Ramracha's abdication, and took the throne himself
as Intharacha I.
Two princes on a bridge
Intharacha I ruled for sixteen years, sending and receiving embassies
from Ming China and intervening in a succession dispute at Sukhothai
without ever fully annexing it. When he died in 1424, his two eldest
sons met on a bridge inside Ayutthaya itself, each mounted on his own
war elephant, to settle the succession by single combat between the
animals - and both princes were thrown and killed in the same
encounter. Their younger brother, left as the only claimant standing,
took the throne unopposed as Borommaracha II - the fifth change of
king in Ayutthaya's first seventy-three years, and the one who would,
within a decade of his own accession, finish what Ramesuen had
started at Angkor.

The siege that ended an empire
expansionDrafted from Wood, A History of Siam (1926)
Borommaracha II, crowned unopposed after his two elder brothers
killed each other in single combat, proved a warlike and capable
king from the start of his reign, and within a few years he turned
his own army south against Cambodia again. His great-uncle Ramesuen
had sacked Angkor once already, a generation earlier, installing a
client king before withdrawing; Borommaracha II went further. His
army invested the Khmer capital itself and held it under siege for
seven months. Tammasok, the Cambodian king, died during the siege -
whether by illness or by the strain of the campaign, the chronicles
do not say - and when the city finally fell, Borommaracha II placed
his own son, the Prince of Inthaburi, on the Cambodian throne as a
client ruler.
A throne that did not stay in Siamese hands
The arrangement did not hold. After the Siamese army withdrew, the
young Prince of Inthaburi died - murdered, according to Cambodian
accounts of the same events - and a Cambodian prince took the throne
in his place under the title Borommaracha Thirat Ramathibodi,
apparently without Ayutthaya contesting it. His first act was to
move the Khmer capital away from Angkor entirely, to Phnom Penh - a
relocation driven by simple geography: Angkor sat dangerously close
to the new Siamese frontier that had just proven it could take the
city twice in one generation. Angkor would never again serve as a
Khmer capital.
A city, not just a treasury
Borommaracha II brought back bronze images and a great number of
prisoners from the campaign - the ordinary spoils of a medieval
siege. But an army that spends seven months occupying a working
capital carries off more than bronze and captives: the men who ran
that capital's own court came north too.
Not a rice kingdom
expansionDrafted from Phongpaichit, A History of Ayutthaya: Siam in the Early Modern World (2017)
Ayutthaya is usually described as a rice kingdom on a fertile delta. Baker and
Pasuk's account, which the chapters here follow, is against the standard
picture.
The Chao Phraya delta was not intensively farmed for export until the nineteenth
century — the great canal-and-paddy landscape of central Thailand is a later
thing — and what the crown actually lived on was trade. Customs on the Gulf
traffic. And, more importantly, royal monopolies on what the hinterland produced:
sappanwood, eaglewood, hides, ivory, tin, and the sea products the China trade
wanted, bought cheap through the corvée system and sold on through the king's own
warehouses to Chinese, Japanese, Persian, Indian and eventually European buyers.
The king was the kingdom's largest merchant, and for some commodities its only
legal one.

A land power that lived like a port
Angkor, a hundred and fifty miles away and the source of Ayutthaya's court
ritual, lived on land tax and almost nothing else. So did its other neighbours
inland. Ayutthaya sat fifty miles up a river with a corvée labour system and a
hinterland empire, and made its money the way Melaka did.
It is worth being careful about what that resemblance means. A strait polity
lives by sitting astride somebody else's route and charging for passage.
Ayutthaya's tolls were collected at a river port it controlled by holding the
whole country behind it — the hinterland was not a route to be taxed but an
estate to be worked, and the monopolies only functioned because the corvée that
supplied them reached deep inland.
Same ledger, then, and a completely different state underneath it.
1688
peakDrafted from Phongpaichit, A History of Ayutthaya: Siam in the Early Modern World (2017)
King Narai's court in the 1680s had gone further toward Europe than any other in
Southeast Asia. His chief minister was a Greek adventurer, Constantine
Phaulkon, who had arrived as an employee of the English East India Company.
There were French troops garrisoned in two forts, at Bangkok and Mergui.
Embassies had gone to Versailles and been received with ceremony. A French
mission in Ayutthaya believed, and reported home, that the king was on the point
of converting to Catholicism.

Phongpaichit, A History of Ayutthaya: Siam in the Early Modern World (2017) · Charles Le Brun · Public domain
In 1688, as Narai lay dying, the commander of the elephant corps seized the
palace. Phaulkon was executed. Narai's heirs were killed. The French garrisons
were besieged and then allowed to leave, and the commander took the throne as
Phetracha.
Siam then dealt with Europeans on its own terms for the next century and a half.
Why the removal held
Elsewhere in the region, a European garrison seized by force tended to come
back with a bigger fleet, or simply never leave. Ayutthaya had foreign soldiers
inside its own capital's defences and removed them in a palace coup, and the
removal held for good.
The difference was not courage or cunning. Ayutthaya was a large
agrarian-labour state with an inland capital and a population it could
conscript, not a port city standing on water a fleet could reach and blockade.
A crown that could raise an army from its own rice-growing hinterland did not
depend on the harbour the way a trading city did, and a coup that expelled a
foreign garrison from an inland capital was not answerable, the way a coastal
sultanate's was, to whatever fleet arrived next season.
After the French
contractionDrafted from Loubère, A New Historical Relation of the Kingdom of Siam (1693)
Simon de la Loubère reached Ayutthaya as Louis XIV's envoy in September 1687
and left in January 1688. Four months later the reign he had been negotiating
with was over, the Greek favourite who had arranged everything was dead, and
the country closed the door he had come through.
His book is the last European description of Ayutthaya before that happened.
What he saw at court
He is exact about the physical protocol, and the protocol is the political
system.

Loubère, A New Historical Relation of the Kingdom of Siam (1693) · Simon de La Loubère · Public domain
When the king moves, the guards follow confusedly and without any order; the
courtiers walk with their hands joined on their breast; and when he stops,
everyone on foot prostrates themselves on their Knees and Elbows, while those
on horses or elephants bow down entirely on the animal.
He notes a category of royal attendants — he transcribes the word as Scham
mow — who follow on foot, and specifies that they are the King's Domesticks,
which are not Slaves, which tells you what the default assumption was.
He records that revolutions are common at Siam and refers his readers to two
earlier accounts for examples, which is a striking thing to print about a court
you have just concluded a treaty with, four months before it happened again.
Why the French were there at all
Because of Constantine Phaulkon, a Greek who had come east with the English East
India Company, entered Siamese service, and risen to run the kingdom's foreign
trade and much of its foreign policy.
Constantine Phaulkon in a seventeenth-century engraving.
Loubère, A New Historical Relation of the Kingdom of Siam (1693) · Pierre-Joseph d'Orléans · Public domain
Phaulkon's project was a French alliance: embassies both ways, French officers,
French garrisons at Bangkok and Mergui, and — the part that destroyed him —
the suggestion to Versailles that King Narai might be converted.
He was not wrong that Ayutthaya wanted a counterweight. The kingdom had spent
the century balancing the Dutch, who had the shipping and were prepared to
blockade the river to get trading terms, against everyone else. What Phaulkon
supplied was a European power with no commercial position in the region and
therefore, in theory, no leverage to use.
1688
Narai fell ill in the spring of 1688. Phra Phetracha, the commander of the
elephant corps, took the palace, executed Phaulkon, killed the heirs, married
into the royal house and took the throne when Narai died.
The French garrison at Bangkok was besieged and allowed to sail away. The
missionaries were imprisoned. The treaties were void.
It is usually described as a xenophobic reaction and it was narrower than that.
The Dutch stayed and went on trading. Chinese, Indian, Persian and Japanese
merchants stayed. What was expelled was a specific arrangement — foreign troops
in Siamese forts under a foreign favourite — that a substantial part of the
court had regarded as intolerable for years.
What the century afterwards looked like
Not decline in the ordinary sense. Trade with China grew through the eighteenth
century and Ayutthaya's Chinese population with it; the rice export to the
Chinese coast became the kingdom's most valuable business.
What did change is that the court stopped taking European powers seriously as
partners and stopped being taken seriously by them, and the succession problem
did not improve. The throne passed by palace violence more often than not, and
the reign that ended in 1767 began with the usual eliminations.
So the kingdom that met the Burmese army in the 1760s was rich, commercially
sophisticated, and had spent eighty years without a stable rule for replacing
its own kings.
1767
endDrafted from Phongpaichit, A History of Ayutthaya: Siam in the Early Modern World (2017)
The Burmese came twice. In 1569 Bayinnaung took the city and Ayutthaya spent
fifteen years as a vassal before Naresuan restored it; the city survived that one
substantially intact.
The second time, in April 1767 after a fourteen-month siege, a Konbaung army took
it, burned it, and carried off what was left of the population. The chronicles,
the law codes, the literature and the palace archive largely went with it, which
is why the history of a state that lasted four hundred years has to be
reconstructed from foreign accounts, from what survived in provincial copies,
and from later recensions made at Bangkok from memory.

What replaced it, and how fast
The state re-formed almost immediately. Taksin held most of the country from
Thonburi by 1770, and Bangkok was founded in 1782 — fifteen years after the
sack.

Phongpaichit, A History of Ayutthaya: Siam in the Early Modern World (2017) · Horiuchi · Public domain
The Chakri dynasty that founded it made the continuity explicit. It rebuilt the
royal precinct on a new river bend to reproduce the old one, re-promulgated the
law code from what could be recovered, had the lost literature composed again by
commission, and put Ayutthaya's own name at the head of its new capital's formal
title, where it still is.
Fifteen years between the destruction of a capital and the founding of its
deliberate replacement is about as short an interval as this kind of thing
takes.
What Bangkok rebuilt
afterlifeDrafted from Phongpaichit, A History of Ayutthaya: Siam in the Early Modern World (2017)
Ayutthaya was destroyed in 1767 and the state was reassembled within fifteen
years, forty miles downriver, by people who had been in it — and the
reassembly was deliberate, itemised, and largely successful.
The interval
The Burmese sack was thorough: the city burned, the population deported or
scattered, the royal family killed or carried off, the archives and the
libraries gone.
Then the Burmese left, because a Chinese invasion of Burma required the army
elsewhere. What was left in Siam was five or six regional warlords, and the one
who won was Taksin — a provincial governor of Chinese descent who had broken
out of the siege with a few hundred men, took the eastern seaboard, then Thonburi
at the river mouth, and had reunified most of the country by 1770.
He reigned fourteen years, went — by the account of the men who deposed him —
mad, claimed to be a stream-enterer on the path to arhatship and had monks
flogged for not prostrating to him, and was executed in 1782 by a general who
took the throne as Rama I.
Rebuilding on purpose
What the new dynasty did at Bangkok is unusual because it was explicit.
The Grand Palace and the temple of the Emerald Buddha were laid out to
reproduce the Ayutthayan royal precinct. The city was sited on a river bend and
canalised to give it an island quarter, as Ayutthaya had been. The ministries
were re-established with the Ayutthayan names and functions. The law was
recompiled in 1805 — the Three Seals Code — from whatever texts had survived,
with the gaps filled by the memory of officials who had served the old kingdom.

The royal chronicles were rewritten too, and this is the part to be careful
with. The versions of the Ayutthaya story that are standard were compiled or
recompiled in Bangkok, by a dynasty that had replaced Taksin and needed the
sequence to run cleanly from the old kingdom through a regrettable interval to
itself.
Taksin's reputation is the casualty. The madness may be true and it is also
exactly what a successor regime would record.
The literature
The most striking single act of reconstruction is the Ramakien.
The Thai version of the Ramayana had existed at Ayutthaya and was largely lost
in the sack. Rama I convened a commission and had it composed again, in 1797,
running to some fifty thousand verses — a national epic rebuilt from fragments
and memory by royal committee, thirty years after the library burned.
The same was done for the Traiphum cosmology, the court poetry, the dance
drama and the mural conventions. The classical Thai culture that exists now is
substantially an early Bangkok reconstruction of an Ayutthayan original, and it
is not always possible to tell which is which.
What that bought
A century later, when Britain had taken Burma and France had taken Vietnam,
Cambodia and Laos, Siam was the one state in the region that was not colonised.
The reasons are usually given as diplomacy and buffer geography, and both are
real. But the thing being defended mattered: a continuous monarchy with an
articulated bureaucracy, a codified law, a national literature and a court that
could negotiate — all of it demonstrably older than the Europeans in the region,
and much of it rebuilt from ashes by men who had watched the original burn.
Ayutthaya is a ruin and a UNESCO site, and it is also the template the country
next door to it is still built on.
Ayutthaya took Angkor in 1431 and the Khmer court moved south to Phnom Penh, taking with it nothing of the ritual apparatus, which stayed and went to Siam.
After an eight-year reign, King Thammaraja II was forced to accept vassal status under Ayutthaya, ending 132 years of independent Sukhothai kingship, though Sukhothai's own kings continued to rule locally for decades afterward.
The Kingdom of Ayutthaya
1351–1767
What led away
1767The Kingdom of Ayutthayaconquered bythe Konbaung dynasty of Burma
A fourteen-month siege ended with the city stormed and burned in April 1767: the population deported or scattered, the royal family killed or carried off, and the archives, libraries and law texts destroyed, which is why the history of a four-hundred-year state has to be reconstructed from foreign accounts and later recensions. The Burmese then withdrew, because a Chinese invasion of Burma required the army elsewhere, and made no attempt to hold the country.
1782Thonburi under Taksin, and the Chakri dynasty at Bangkok
Taksin, a provincial governor who had broken out of the siege with a few hundred men, held most of the country from Thonburi within three years. After his deposition in 1782 the Chakri dynasty founded Bangkok on the opposite bank and reassembled the state on purpose: the royal precinct laid out to reproduce Ayutthaya's, the ministries re-established with their old names, the law recompiled in 1805 from surviving texts and the memory of officials who had served the old kingdom, and the lost literature composed again by commission. Ayutthaya's own name still stands at the head of Bangkok's formal title.
