Ayutthaya: Four Centuries of a Cosmopolitan Capital (1350–1767)

For more than four centuries, from its foundation in the mid-fourteenth century to its destruction by Burmese armies in 1767, Ayutthaya was far more than a royal residence. It was a capital built on water and open to the gulf, and a court where a Persian merchant, a Greek adventurer, French Jesuits and Siamese ambassadors bound for Versailles all crossed paths. Its history can be read through a handful of figures: U Thong, Naresuan, Narai, Phaulkon, Phetracha, Ekkathat. It can also be read through its neighbours, Sukhothai, Cambodia and the Burmese dynasties, whose fates became entwined with its own. Even so, one must remain wary of sources that were largely rewritten after the fall.

The birth of a kingdom facing the gulf

The first problem Ayutthaya poses is its date of birth. ICOMOS, in the evaluation drafted in 1990 ahead of its World Heritage inscription, gives 1350, as does the UNESCO listing. Thai tradition sets the official foundation on 4 March 1351. The gap is slight. Yet it serves as an immediate reminder that this kingdom's chronology rests on texts that must be read with caution.

The founder bears two names. The first, U Thong, is the one retained by collective memory. The second, Ramathibodi (transcribed as Ramadhipati by ICOMOS), is his reign name. ICOMOS presents him as a rebellious Thai vassal who had himself crowned and then obtained an oath of allegiance from Sukhothai. His reign ended in 1369 and he was succeeded by Ramesuan. His date of birth, on the other hand, rests on no solid source.

Why this site? UNESCO's description puts forward a geographical reason. The city is said to have been established upstream of the point reached by the tidal bore from the gulf: far enough from the sea to escape warships, and in a position that protected it from seasonal floods. The same listing describes a city laid out on a rigorous grid of roads, canals and moats. It was a capital designed around water, as much to defend itself against it as to move about upon it.

A union of regional centres

Several overviews describe the kingdom's birth as the joining of two entities in the central plain. The first was Suphannaphum, around present-day Suphanburi. The second was Lavo, around Lopburi. To these was added the annexation of Phrip Phri, present-day Phetchaburi. This interpretation awaits confirmation from specialist research, but it sheds light on the political life of the early decades. The throne was then contested between lineages linked to Suphanburi and to Lavo, with disputed successions in 1370, 1388 and 1424.

The historians Chris Baker and Pasuk Phongpaichit, in A History of Ayutthaya: Siam in the Early Modern World (Cambridge University Press), propose a shift in perspective. In their view, early Ayutthaya was not an agrarian society resting on a large labour force. Even before 1351, it was an entity facing the sea, living by raiding and trade, and relatively unconcerned with Buddhist monuments or writing. This ‘rough’ city-state would only later have become the extensive, cosmopolitan kingdom with a complex administration that foreigners would call ‘Siam’.

Sukhothai: a lineage to be qualified

ICOMOS describes Ayutthaya as the ‘second Siamese capital’ after Sukhothai. The phrase reflects a narrative of continuity that has become standard. It should not obscure a more fluid reality. Sukhothai was at first a neighbouring power whose allegiance Ayutthaya sought. This northern centre still appears, in 1568–1569, among the allies of the Burmese against Ayutthaya. The stages of its integration have yet to be documented precisely. In any event, they rule out projecting onto the fourteenth century the unity of a state that did not yet exist.

Chronicles written after the fact

One difficulty runs through this entire history. The royal chronicles of Ayutthaya were largely rewritten at the end of the eighteenth century, after the city's fall. These phongsawadan (dynastic chronicles) therefore reflect the concerns of the courts that succeeded Ayutthaya as much as the reality of the centuries they recount. As the review of Baker and Pasuk's book published by H-Net points out, it is difficult to gauge from them the true scale of the kingdom's transformation. The most celebrated episodes, duels and heroic deeds, come from texts written after the events.

Under the threat of Toungoo: vassalage and Naresuan's revenge

In the sixteenth century, the decisive neighbour was Burma under the Toungoo dynasty. The war of 1568–1569 traces a revealing map of regional alliances. Lan Xang, the Lao kingdom, fought alongside Ayutthaya. Lan Na, the northern kingdom, and Sukhothai sided with the Burmese. The outcome was a Burmese victory, and Ayutthaya passed under Toungoo suzerainty for some twenty years. The political geography of the period did not, therefore, pit ‘Thais’ against ‘Burmese’. It set kingdoms and principalities against one another, each choosing its side according to its interests of the moment.

Naresuan and Ekathotsarot

The break came with Naresuan, whose reign is generally dated from 1590 to 1605. With his brother Ekathotsarot, he led the rebellion against Burmese suzerainty. The conflict of 1584–1593 ended with Siamese independence. Ayutthaya would not fall under Burmese domination again until 1767, more than a century and a half later.

The episode that encapsulates this revenge is the battle of Nong Sarai, in January 1593. According to the classic version of the Siamese chronicles, Naresuan fought the Burmese crown prince Mingyi Swa in single combat on elephant-back and killed him. The same chronicles give the name of his elephant, Phraya Chayanuphap. They add that Ekathotsarot likewise defeated a Burmese general, Mangcacharo, in a duel.

A duel whose story falters

The scene has become a national emblem, but it stands up poorly to scrutiny of the sources. The Burmese chronicles date the battle to 8 January 1593, the Siamese chronicles to 18 January. Above all, the Burmese chronicles have Mingyi Swa killed by a gunshot, not at the end of single combat. The historian Barend Jan Terwiel compared indigenous and European sources in the Journal of the Siam Society. He identifies at least ten different accounts of the battle, which diverge sharply, and his reading places the arrival of the Burmese army in February 1593. The most prudent course is to present the duel as a story handed down by the royal chronicles, rather than as a fact established in its details.

Cambodia and the Iberian shadow

Regained independence immediately altered the regional balance. The Siamese–Cambodian war of 1591–1594 ended in victory for Ayutthaya and the reduction of Cambodia to vassal status. The detail is not insignificant: Cambodia then enjoyed the support of Spain and Portugal. By the end of the sixteenth century, the European powers were already parties to mainland rivalries. They were not content merely to trade in the ports.

Narai and the court at Lopburi: Siam faces Europe

The reign of Narai, from 1656 to 1688, marks the high point of Ayutthaya's relations with Europe. Born in 1632, he belonged to the so-called Prasat Thong dynasty. He divided his court life between Ayutthaya and Lopburi, where he spent part of each year.

A Greek favourite and a Persian house

The most singular figure of this reign is Constantine Phaulkon. Born in 1647 at Erisso, on the island of Cephalonia, then under Venetian rule, he married Maria Guyomar de Pinha in 1682 and became the king's favourite. His rise was meteoric. In 1683 he obtained the office of Phra Khlang, minister of the treasury. From 1685 to 1688 he held the post of Samuhanayok, head of the civil government.

A study published in Damrong, the journal of Silpakorn University, has reconstructed his residence at Lopburi. It shows just how much the court was a meeting place. Before 1683, the house belonged to a Persian merchant in Narai's service. Between 1683 and 1685 it was converted to house Phaulkon and to receive the French embassy of the Chevalier de Chaumont. It remained his home until 1688. The very walls of Lopburi thus preserve the trace of three worlds: the Siamese court, Persian merchant networks and European diplomacy.

Embassies in both directions

Exchanges with France set the rhythm of the decade. In 1685 the first French embassy arrived, led by the Chevalier de Chaumont and accompanied by the Abbé de Choisy. A famous engraving shows Narai observing a lunar eclipse at Lopburi that same year, in the company of French Jesuits. The image speaks of the court's interest in knowledge from Europe.

In return, Phaulkon chose Kosa Pan to accompany the Chaumont embassy on its journey home. In 1686 he led the Siamese embassy to Versailles, where it was received by Louis XIV. Thai memory has nicknamed him ‘the ambassador with the golden tongue’. A second French embassy, that of La Loubère, followed in 1687. For a few years, Ayutthaya and Versailles regarded each other as partners. France saw in Siam a sphere of influence; Siam saw in France one counterweight among others.

1688: Phetracha's ‘revolution’

This balance broke down abruptly. In March 1688, Narai fell gravely ill. According to certain secondary sources, which need to be cross-checked, he is said to have designated his daughter, Princess Yothathep, as his successor in May. Events then unfolded very quickly:

• 17–18 May: Phetracha seizes the palace at Lopburi, and Narai is placed under house arrest;
• 18 May: Phaulkon is arrested;
• 20 May: Mom Pi, the king's adopted son, is executed;
• 5 June: Phaulkon is beheaded at Lopburi;
• 10 or 11 July: Narai dies, and Phetracha succeeds him.

Historians speak of the ‘revolution’ of 1688. The term covers at once a succession crisis, the elimination of a foreign favourite who had become all-powerful, and a reaction against the French presence. One should beware of turning this coup into a definitive closing-off of the kingdom. What followed, as the debate over the eighteenth century shows, calls for nuance.

An eighteenth century in decline? An open debate

For a long time, Ayutthaya's last century was read as one of waning vigour. In the second volume of Southeast Asia in the Age of Commerce (1993), Anthony Reid argues that Southeast Asian trade receded in the eighteenth century. Baker and Pasuk dispute this reading for Ayutthaya. In their view, the kingdom's trade remained robust until the fall, driven by growing exchanges with China. Cosmopolitanism, then, would not have disappeared with the departure of the French. It would have changed direction, from Europe towards the Chinese world.

The two authors also put forward a climatic hypothesis, presented tentatively by the H-Net reviewer. Low rainfall, linked to variations in climate, might explain some of the kingdom's military failures. The idea deserves attention in a capital whose defence relied largely on water. It nonetheless remains a line of research, not a proven explanation.

This debate has a direct bearing on how 1767 is read. If the kingdom was not in decline, its fall cannot be explained by internal weakening. One must then look towards its western neighbour.

1765–1767: the fall, seen from Burma as much as from Siam

By the mid-eighteenth century, Burma had changed its face. The Konbaung dynasty, founded by Alaungpaya, was in full expansion. A first campaign, in 1759–1760, was cut short: Alaungpaya withdrew, ill, as the floods approached. His son Hsinbyushin, who reigned from 1763 according to most chronologies, relaunched the offensive in 1765. His generals were Maha Nawrahta and Ne Myo Thihapate.

Why attack Ayutthaya?

The library of KMUTT university in Bangkok reports three competing explanations:

• for the historian D.G.E. Hall (A History of South-East Asia), the pretext for the 1759–1760 campaign was Siam's refusal to hand over Mon rebels who had taken refuge there;
• according to The King Taksin the Great (Old Palace Conservation Foundation, 2000), Hsinbyushin wanted to destroy Ayutthaya completely, accusing it of encouraging revolts in Burma's vassal states;
• for Wisetchaicharee (1998), Siam had failed to send the tribute promised to Alaungpaya.

These motives are not mutually exclusive. All of them show a Siam embedded in a regional game: a land of asylum for the Mon, a rival suspected of fomenting dissent, a defaulting tributary partner. The war of 1765–1767 was a matter of rivalry between two states contending for borderlands and vassals. It was not an ancestral hatred between two peoples.

The siege and the fall

The siege began in January or February 1766. It took place while Qing China had launched its first invasion of Burma. The Siamese were counting on the rainy season to force the besiegers to withdraw, as in 1760. Hsinbyushin nevertheless maintained the siege. The city fell on 7 April 1767. The last king, Ekkathat, met his death there. High dignitaries were taken prisoner, among them the Chaophraya Phrakhlang and the Phraya Yommaraj and Phollathep (Chaophraya and Phraya being titles borne by senior dignitaries). Among the Siamese commanders was Phraya Tak, the future King Taksin.

The figures often cited must be handled with great caution, as their sources have not been verified. They speak of more than 40,000 Burmese soldiers against some 20,000 Siamese, and of more than 20,000 dead and 30,000 deported. The Burmese occupation lasted until November 1767. In the unoccupied Siamese territories, a period of civil war began.

The other side of victory

For Burma, this triumph came at a cost. Waging war simultaneously against Siam and China nearly cost it its independence. Hsinbyushin had to withdraw his troops from Siam in haste, and a fragile truce was concluded with China in 1769. The fall of Ayutthaya thus belongs to a wider crisis, in which Chinese pressure in the north weighed on Burmese ambitions in the east.

Memory, heritage and uses of the past

The memory of these wars was profoundly shaped in the modern era. Prince Damrong Rajanubhab's work, Our Wars with the Burmese, is said to have contributed greatly to establishing the image of the Burmese as the enemy of the Thai nation. Films such as Suriyothai, Bang Rajan and King Naresuan have extended this glorification. This national narrative is not without foundation, since the wars were real and devastating. But it simplifies a past in which Sukhothai, Lan Na and Cambodia changed sides, in which the Mon sought refuge in Siam, and in which the court of Ayutthaya entrusted its finances to a Greek.

The site itself was inscribed on the World Heritage List in December 1991, as number 576, under criterion (iii), which recognises testimony to a vanished civilisation. The prang (reliquary towers) and monumental monasteries bear witness to its former splendour. The grid of canals and moats recalls what the city once was. The Fine Arts Department, the Thai authority responsible for heritage, drew up and implemented a master plan for conservation and enhancement. After the floods of 2011, an ICOMOS advisory mission recommended extending it to flood management. Water, which protected the capital in the fourteenth century, has become one of the chief threats to its remains.

Ayutthaya can be reduced neither to a succession of kings nor to a field of ruins. It is the story of a power born of trade and the river, which grew by negotiating with its neighbours as much as by fighting them. Its sovereigns, favourites and ambassadors placed Siam within a world stretching from Versailles to China. Its story remains partly to be reconstructed, from rewritten chronicles, foreign testimonies and remains that are still being protected.
