Walking through the leafy Bangkok campus today, accompanied only by the whisper of distant traffic and the flowing river, it is hard to imagine the horrific scenes that unfolded here 50 years ago.
On October 6, 1976, scores of student protesters besieged inside Thammasat University were killed by security forces and right-wing paramilitaries.
Though half a century has passed, no one has ever been prosecuted for the atrocity, leaving unresolved questions and an open wound that still divides the nation.
The students had gathered at the riverside campus to protest the return of exiled dictator Field Marshal Thanom Kittikachorn, who had re-entered Thailand and ordained as a Buddhist novice monk. Thanom had fled three years earlier amid public fury over his military regime’s bloody crackdown on a student-led uprising in October 1973.
Jolted by rumours that Thanom’s return was the prelude to a military takeover, thousands of students flooded Thammasat – a historic hub of democratic resistance.
Political tensions grew when two labour activists who had been pasting anti-Thanom posters were found lynched. Students responded by staging a protest play of the lynching. Right-wing newspapers then alleged that the student in the mock hanging intentionally resembled the Crown Prince, inflaming anger among royalists.
Meanwhile, anti-leftist fervour among police and security forces flared over reports that communists had joined the protest.
On the morning of October 6, heavily armed security units blocked the exits and stormed the university.
The guns reportedly fell silent three hours later at around 11am, leaving dozens of protesters dead and wounded. Surrendered students were forced to strip to their underwear and lie face down, with reports that some female protesters were sexually assaulted.
Shocking scenes
Several bodies of dead protesters were dragged onto the field and mutilated by angry mobs, who kicked, cut, urinated on, lynched and battered the corpses with planks and other objects. Others were pulled along the ground by cloth tied around their necks or piled up and set on fire, according to an independent archive of the massacre. The body of one young female protester was stripped bare by the mob.
At least five bodies were hung from trees at the royal field of Sanam Luang, across the road from Thammasat University.
The theatre of cruelty was captured in a photograph of a man raising a folding chair over his head to bludgeon the lifeless body of a protester hanging from a Sanam Luang tree as the crowd looks on.
Some of the audience look stunned; others are smiling. This iconic image won American photographer Neal Ulevich a Pulitzer Prize in 1977 for “photographs of disorder and brutality in the streets of Bangkok”.
While the official death toll was 45 – 40 protesters and five officers – historians and human rights groups give estimates ranging from 100-plus to over 200. Officially, 145 people were injured in the incident and over 3,000 arrested.
Mainstream Thai history textbooks either give a brief mention of the incident or omit it altogether.
‘Let bygones be bygones’
Just hours after the incident, the elected government of Seni Pramoj was toppled in a military coup. The coup-makers installed law professor Thanin Kraivixien as the prime minister, but his government lasted barely a year before being ousted by another military takeover.
In 1978, the regime of General Kriangsak Chamanan granted a blanket amnesty for October 6 protesters, state officials, and right-wing militias.
“Let bygones be bygones. Please, just forget about it,” Kriangsak reportedly said after the pardon was granted.
Critics argue that the absence of accountability for the massacre is emblematic of a culture of impunity that continues to plague Thailand and prevent genuine social reconciliation.
Fears of communism
The October 6 incident occurred amid mounting fears of a communist takeover in Thailand. As Vietnam, Laos, and Cambodia fell under communist rule, many feared that the kingdom would be the next domino to fall in Southeast Asia.
During the 1970s, political instability and economic hardship deepened the divide between the socialist-leaning left and the conservative, royalist right in Thailand.
Anti-communist sentiment was widespread, while leftist ideas gained traction among young people who read banned books and listened to underground music celebrating socialism.
Political scientist Prof Kasian Tejapira, who took part in the 1976 protest as a university student, argues that the deadly October 6 crackdown and the ensuing military coup were plotted by the “deep state”.
The aim, he said, was to reverse the October 14 “bourgeois revolution” three years earlier, which had seen power switch from Thailand’s bureaucratic elite to its emerging middle class.
Kasian described the October 6 incident as “a war between the left and the right”, unfolding amid upheaval at the domestic, regional, and global levels. Domestically, the government was fighting the Communist Party of Thailand.
Regionally, communist forces had taken over all three Indochinese states since 1975. Globally, the Cold War pitted the US-led capitalist bloc against the socialist bloc led by the Soviet Union.
‘Transitional justice’ approach
Historian Thongchai Winichakul, a survivor of the violent October 6 crackdown, has called for an end to impunity as a crucial step to preventing recurrent political violence. “This can be achieved only by clearly establishing the boundary between the lawful and unlawful exercise of state power,” he wrote recently.
Thongchai was among the 3,094 protesters arrested and one of 18 protest leaders who spent nearly two years in detention before being pardoned.
He argues that October 6 justice and reconciliation remain possible despite the blanket amnesty.
Pointing to foreign precedents, he highlighted South Korea’s response to the deadly 1980 Gwangju Uprising, saying the country had transformed the memory of loss into a force for democratic progress by restoring dignity to those affected and building a culture that rejects violence against the public.
To prevent a repeat of the October 6 incident, Thongchai suggested Thailand deploy so-called transitional justice through four measures:
- Preserving collective memory and uncovering the historical facts.
- Prosecuting those responsible and restoring justice in accordance with legal principles and due process.
- Providing both material and non-material reparations, including apologies and raising public awareness of past wrongs.
- Reforming the state institutions and mechanisms involved in abuses of power that led to injustice and brutality in the past.
Marking the incident
Events are being held across the capital to mark the 50th anniversary of October 6.
Thai PBS is holding an exhibition titled “50 Years of October 6: From Scars to the Future” at its headquarters on Vibhavadi Rangsit Road until October 16. Themed “6 Scenes, 6 Perspectives”, the exhibition features poetry, songs, and artworks that shed light on one of Thailand’s darkest chapters, along with questions and answers contributed by people of all ages. Admission is free.
Thammasat University is holding its annual commemoration at the Tha Phrachan campus, site of the bloody crackdown.
The university’s rector, Prof Supasawad Chardchawarn, will preside over a moment of silence for those who lost their lives, followed by a reading of their names. Wreaths will be laid at the campus memorial, a student will read a commemorative poem, and representatives of nine invited organisations will deliver tributes to the “October 6 heroes”.
Chulalongkorn University, Thammasat’s sister institution in Bangkok, held activities to mark the incident’s 50th anniversary in early October, including an exhibition, musical performances, panel discussions, and academic lectures.
