When the walls of Ayutthaya fell in April 1767, the flames were lit by the Burmese army. But the people who truly brought the city's reign as a capital to an end were two Siamese kings. Taksin chose never to rebuild it, while Rama I later ordered the remaining walls to be dismantled so their materials could be used to construct a new capital.
Ayutthaya had served as the capital of the Siamese kingdom since 1351. At the height of its prosperity, the city welcomed merchants and diplomats from Europe, Persia, China, and Japan.
Before the 18th century, it was one of Southeast Asia's most cosmopolitan capitals. Four centuries later, the city not only fell to a foreign invader but was also abandoned by its own successors.
A Different Kind of Destruction
The fall of Ayutthaya in 1767 was not the first time the city had been captured by Burma. In 1569, King Bayinnaung had already conquered the kingdom.
At the time, Bayinnaung chose not to destroy the city. Instead, he replaced its king and turned Ayutthaya into a vassal state while allowing it to remain intact. The strategy proved short-lived. Within 15 years, Ayutthaya broke free and regained its independence.
Two centuries later, the next Burmese king had no intention of repeating the same mistake. In 1767, Hsinbyushin led a second invasion of Ayutthaya and rejected the idea of keeping it as a vassal state. He demanded unconditional surrender instead.
His decision was driven by more than revenge. At the time, the Qing dynasty of China was invading Burma itself. Hsinbyushin knew he might never have another opportunity to return if Ayutthaya rebelled again as it had before.
He chose to eliminate the kingdom once and for all, even if it meant carrying out a prolonged siege that lasted 14 months from February 1766.
The city's walls were finally breached on 7 and 8 April 1767. Burmese forces systematically burned palaces and temples, melted down gold-covered Buddha statues, and left the city in ruins.
Once home to around one million people, Ayutthaya became a devastated landscape with bodies filling its moats. Ayutthaya's last king, Ekkathat, was killed while attempting to flee the city.
Why Taksin Never Returned
Within months of Ayutthaya's fall, Taksin, a general of Chinese descent who had succeeded in regrouping the Siamese forces, defeated the remaining Burmese troops as well as local rulers competing for power.
On 28 December 1767, he was crowned king. The coronation took place not in Ayutthaya but in Thonburi, across the Chao Phraya River.
His first reason was practical. Ayutthaya was simply no longer fit for habitation. Its palaces and temples had been reduced to rubble and ashes, while the aftermath of the war left the city filled with corpses and vulnerable to disease outbreaks.
His second reason was strategic. Ayutthaya was easily accessible to invading forces by both land and river. Thonburi, by contrast, was easier to defend, closer to the sea, and already home to a well-established Chinese trading community. T
his provided an important foundation for restoring rice supplies and reviving the economy through the maritime trade networks that Taksin already knew well.
There was also a political reason. Thai historian Nidhi Eoseewong argued in Pen and Sail: Literature and History in Early Bangkok (1984) that key positions in Taksin's new court were filled largely by his own followers, many of whom came from Chinese merchant backgrounds, rather than by surviving nobles from Ayutthaya. Establishing a new capital also meant breaking the political continuity of the old aristocracy.
The King Who Dismantled What Remained
Taksin ruled for only 15 years before being overthrown in 1782 by one of his own generals, Phraya Chakri, who came from the old Ayutthayan aristocracy. Phraya Chakri then ascended the throne as Rama I.
Yet even after power returned to the old nobility, the capital was not moved back to Ayutthaya. Instead, Rama I founded Bangkok directly across the river from Thonburi.
He went even further by ordering bricks from Ayutthaya's fortifications and city walls, rather than its temples, to be transported by barge along the Chao Phraya River. The materials were used to construct Bangkok's city walls and the Grand Palace in 1783.
Historical accounts suggest that the workers avoided dismantling temple structures. They removed bricks only from the city's fortifications, walls, and royal palace. The distinction suggests that the demolition targeted the symbols of the old kingdom's political authority rather than its religious sites.
The remains of Ayutthaya's royal palace were eventually demolished completely by the successors of the very kingdom that had once ruled from it.
A City of Ruins for Nearly a Century
According to a 2019 study by Thai historian Nichapa Thichakornsakul, published in the Journal of the Thai Khadi Research Institute, Bangkok's elite viewed Ayutthaya largely as a ruined city throughout the reigns of Rama I to Rama III.
Only a handful of temples, including Wat Suwandararam and Wat Na Phra Meru, received limited repairs as part of Buddhist merit-making practices.
More substantial restoration efforts, including work at Wat Chumphonnikayaram and Chandrakasem Palace, did not begin until the reign of Rama IV, nearly a century after the city's fall in 1767.
The motivation was not primarily to honor the past. Instead, growing pressure from Western colonial powers prompted Siam to demonstrate the grandeur of its own history.
