History
On This Day: Police, Military, and Ultra-Royalist Extremists Killed 40–500+ Students and Left-Wing Protesters, October 6, 1976
NSFW
The 6 October 1976 massacre, commonly called the 6 October event, was a violent crackdown against students and left-wing protesters at Thammasat University in Bangkok on 6 October 1976. Police, military forces, and right-wing paramilitary groups attacked the university after several years of intense political polarization following the fall of the military dictatorship in 1973.
Background
In October 1973, mass protests forced the military dictatorship of Thanom Kittikachorn out of power. Thailand subsequently experienced a period of greater political freedom, with student movements, labor unions, left-wing organizations, and other progressive groups becoming increasingly influential.
At the same time, conservative and royalist forces became increasingly concerned about the growth of communism. The communist victories in Vietnam, Laos, and Cambodia in 1975 intensified these fears.
The political conflict became increasingly violent. Right-wing groups such as the Village Scouts, Nawaphon, and Red Gaurs were mobilized against students and left-wing activists. Anti-communist rhetoric increasingly portrayed the student movement as a threat to the monarchy and the Thai state.
Return of Thanom
Former dictator Thanom Kittikachorn returned to Thailand in September 1976 despite widespread opposition.
His return caused major demonstrations. Thanom entered the monkhood at Wat Bowonniwet, a temple with close royal associations.
On 23 September, King Bhumibol Adulyadej and Queen Sirikit visited Thanom. This further angered opponents of the former dictatorship and intensified political tensions.
Two labor activists were subsequently murdered and hanged in Nakhon Pathom on 24 September. Their deaths became an important catalyst for renewed student protests.
The Thammasat protest
On 4 October, students at Thammasat University staged a dramatic reenactment of the hanging of the two murdered activists.
A photograph of the performance was published by the right-wing newspaper Dao Siam on 5 October. The newspaper and other right-wing media claimed that one of the students appeared to resemble Crown Prince Vajiralongkorn.
The incident was portrayed as an insult to the monarchy and lèse-majesté.
Army-controlled radio stations broadcast increasingly inflammatory accusations against the students and called for action against the supposed communist and anti-monarchist threat.
Right-wing groups mobilized toward Thammasat University while police and Border Patrol Police units moved into Bangkok.
By the night of 5 October, thousands of armed police and paramilitary personnel had surrounded the university.
The massacre
At approximately 5:30 a.m. on 6 October, security forces began firing into Thammasat University.
The attackers used assault rifles, machine guns, grenades, grenade launchers and other military weapons.
Students attempted to surrender and negotiated with authorities, but the attack continued.
Around 7:30–8:00 a.m., security forces entered the university.
Students attempting to escape were shot, beaten, tortured, lynched, or otherwise attacked. Some people attempting to flee across the Chao Phraya River were shot at.
Photographs from the massacre show students being beaten, bodies hanging from trees, and crowds of right-wing supporters participating in or watching the violence.
Some surrendered students were forced to lie face down and strip to their underwear. Reports also documented sexual violence, robbery, torture, and other abuses.
The violence was not limited to students who were actively fighting. Many victims were attempting to surrender or escape.
Death toll and casualty estimates
The exact number of people killed remains disputed.
The major estimates cited include:
45 deaths: the commonly cited official figure.
40 protesters/students plus 5 perpetrators: the breakdown associated with the official count.
45 protesters: historian Thongchai Winichakul's adjusted figure, which accounts for a victim who died later while in custody.
100+ deaths: estimated by former Bank of Thailand governor and Thammasat rector Puey Ungphakorn.
500+ deaths: a much higher estimate attributed to the Ruam Katanyu Foundation.
167 wounded: an official casualty figure.
3,094 people detained following the massacre.
Because records were incomplete and the event occurred during a period of intense political repression, the true number of deaths has never been conclusively established.
The 45-person figure is the most commonly recognized formal death toll, while estimates of 100 or more have appeared in historical accounts.
The military coup
That evening, the military carried out a coup.
The National Administrative Reform Council (NARC), led by Admiral Sangad Chaloryu, overthrew the civilian government.
The coup leaders justified their actions by claiming that Thailand faced a communist and anti-monarchist threat and that intervention was necessary to protect the monarchy and national security.
King Bhumibol subsequently appointed Thanin Kraivichien, a strongly anti-communist and royalist judge, as prime minister.
Thailand therefore went from a period of post-1973 democratic liberalization to another authoritarian government within a single day.
What happened to the students
Thousands of people were arrested following the massacre.
Approximately 3,094 students and civilians were detained.
Many detainees reported physical abuse and other mistreatment.
Eighteen student organizers were eventually prosecuted, but they were later released under an amnesty.
Importantly, those responsible for the massacre were not successfully prosecuted.
Amnesties passed in 1976 and 1978 helped establish broad immunity for those involved in the violence and the subsequent coup.
As a result, the massacre became a major example of political violence followed by institutional impunity.
The role of the monarchy
The role of King Bhumibol and the royal institution remains one of the most politically sensitive aspects of the event.
There is well-established evidence that the monarchy had relationships with conservative and anti-communist organizations during this period, and members of the royal family interacted with some of the groups involved in the broader anti-left mobilization.
However, the extent to which the king personally knew about, encouraged, approved, or directed the violence remains a matter of historical debate.
It is therefore important to distinguish between:
Established fact:
The king visited Thanom after Thanom returned to Thailand, the monarchy had close relationships with conservative political forces, and the king subsequently appointed the post-coup government.
Contested interpretation:
The precise degree of royal knowledge, authorization, or responsibility for the massacre itself.
This distinction is particularly important because discussion of the monarchy's political role was heavily constrained in Thailand for decades.
Right-wing organizations
Several right-wing organizations played important roles in the political environment surrounding the massacre.
Village Scouts were a large anti-communist mass organization with strong royalist associations.
Nawaphon was an anti-communist movement with connections to conservative political and religious networks.
Red Gaurs were a militant anti-left organization that included former soldiers, vocational students, unemployed youths, and others.
These organizations helped create the political environment in which students were increasingly portrayed as enemies of the nation, religion, and monarchy.
Some religious figures also promoted extreme anti-communist rhetoric. One particularly notorious example was the monk Kittivudho Bhikkhu, who argued that killing communists did not necessarily constitute a serious moral transgression because communists were supposedly not fully human.
Such rhetoric contributed to an environment in which political opponents could be dehumanized.
Political consequences
The massacre effectively ended the democratic opening that had followed the 1973 uprising.
The new government imposed severe restrictions on political activity, suppressed left-wing organizations, and intensified anti-communist repression.
Some students and activists fled into the countryside and joined the Communist Party of Thailand, contributing to an increase in the communist insurgency.
The massacre therefore had the paradoxical effect of pushing some young political activists toward the very communist movement that the government had claimed to be fighting.
Historical memory
For decades, discussion of the massacre was politically sensitive.
The event was often referred to simply as the "6 October event", rather than being given a more explicit description such as "massacre." The ambiguity reflected the difficulty of publicly confronting responsibility for what happened.
The absence of meaningful prosecutions for those responsible became a central part of the historical trauma.
The massacre continues to be commemorated every year, particularly at Thammasat University.
It remains one of the most important examples of state and right-wing political violence in modern Thai history.
In one sentence
On 6 October 1976, police, military forces, and armed right-wing groups attacked left-wing students at Thammasat University amid intense anti-communist and royalist mobilization, killing at least 45 people according to official records, with historical estimates ranging from 45 to 100+ and one contemporary estimate exceeding 500, before a military coup overthrew the civilian government that same evening and largely shielded those responsible from prosecution.
People posting here that this is justified because they were communist sympathizers are diabolical.
But not surprising. It explains why Thailand is still a developing country; people justify brutal dictatorships and coups because of red scare.
People complain about foreigners taking jobs and low wages, but will also vote against any party that tries to implement labor protection/ minimum wage for Thai citizens because it is “socialism” and “communism” 💀
All the massacres in Thailand, of which there have been several more after this one, three massacres with thousands of dead civilians in the 21st century alone, and no one has ever been held accountable and, unfortunately, the people have remained relatively passive about it.
I kinda agree with SomJiam on this one "communist erasure is real and problematic", it doesn't justify the killing but at least we shoud talk on the basis of truth not revisionism.
When they killed people on the opposing side, they kept it quiet? Invaders' right?
Officials and villagers collect the bodies of nine villagers killed by communist insurgents.
Villagers recount the brutal atrocities committed by communist insurgents.
On December 13, 1974, during a clearance operation in the area around Lam Huai Bang Sai in Na Kae District, Nakhon Phanom Province, authorities discovered that Phang Daeng Village, Dong Luang Subdistrict, Na Kae District, which had once been a large village with fertile land and abundant water, had become completely deserted. It was unknown where the villagers of Phang Daeng had gone.
At 6:45 a.m. on December 13, 1974, it was reported that 29 residents of Phang Daeng Village, both adults and children, had escaped from communist insurgents and sought protection at Roi R. 2070 military base, located on Phu Phek.
They reported that the entire population of Phang Daeng, numbering approximately 500 people, had been threatened and forced by communist insurgents to move into the forest. The purpose was to provide food and other support to the insurgents. The villagers said they had managed to escape with only 29 people, while the others remained trapped in the forest.

Who exactly is “they”? You’re comparing communist insurgents to university students and left-wing protesters who were massacred on October 6. The fact that communist insurgents committed atrocities against villagers does not make those students insurgents, nor does it justify or explain their killing. If your argument is that the students were part of an armed insurgency, then provide evidence for that claim.
Are you sure those students who were carrying guns didn't end up shooting other students?
On the night of October 5th, I was inside Thammasat University, around the Faculty of Law. Since late at night, there had been constant harassment with sporadic gunfire echoing around. At first, they sounded like ordinary handguns. That night, I was on duty as a guard.
When the other side fired at us, I returned fire using my own pistol. However, I didn’t know if my shots hit anything. Then, around 6:00 AM, I was startled by a loud BOOM!
It definitely didn't sound like a small firearm anymore.

So your solution is to shoot the other students too that didn't have weapons? It's amazing people with your intelligence manage to reach the upper echelons of Thai society.
Wanna be rich and successful like Singapore?? Sweep out all the commies was their most important victory. Otherwise they make your country to be rotten within
After October 6, thousands of students with Thai nationals joined communist base camps along Thailand’s borders.
The question is: how did they know whom to contact to join these camps if they weren’t pro-commie from the beginning? You couldn’t simply show up at a camp without getting shot.
Trust was everything in those circles. They took it so seriously that even their toilets had no walls-just to make sure no one could conspire in private.
Some students joining the communist insurgency after October 6 does not prove that the students at Thammasat were all communists beforehand. There is no evidence that all, or even necessarily most, of the students who were killed were members of the CPT.
And regardless of what happened afterward, the people responsible for the October 6 massacre were not meaningfully held accountable. You can't justify the killing of an entire group based on the fact that some members of that group later joined an insurgency, particularly when that very crackdown may have helped drive people toward the communist movement in the first place.
I never defended the communists, I just believe like you those in power at the time are incredibly short sighted and only hurt themselves in their actions and words. If they had actually listened to the left wing students or allowed them to protest the communist insurgency wouldn't have been bad. Communism gets defeated by economic development, not violence.
Based on what you said, are you sure Thailand didn't end up being ruled by communists? Do we have to make policies that help invaders invade even more and take over from native Thais?
Does Thailand ban them from working in government jobs and making national policy, like Malaysia does? If they had more power in the military, they wouldn’t hire Thais the same way.
TF are you on about, go bark for your elitist masters. you dog. There's no such thing as a native Thai and will never be, that is what makes Thailand better than Malaysia. We absorbed the people we settled next to (The Mon), the people we conquered (The Khmer) and the people we let in (The Chinese, Portuguese, Cham).
Don't you know that this is one of the propaganda pieces spread by commies in Thailand to invade other country, claiming that there is no Thai ethnicity?
May I ask you if there is a Han ethnicity? Is only your group pure-blooded?
Pretty sure it was Plaek Phibunsongkhram who spread this idea in order to strengthen the unity of Thai people, not the commies. Get your facts straight.
That article doesn't say all the students had weapons. It is a retrospective interview with one former police officer describing shooting from inside the university. Even if we accept his account completely, that establishes that there were armed people inside the campus, not that every student was armed.
There is an important distinction between “some students fired weapons” and “the students were all armed combatants.” Thousands of students were arrested and searched after the campus was taken. Contemporary accounts also describe student security groups having some firearms, while other students were unarmed and simply trying to escape or surrender.
So if you're using this article to claim that every student at Thammasat was armed, where does the article actually say that? It doesn't.
And even evidence of armed students would not establish that the people who were killed were the people firing. Several thousand people were on that campus. You can't turn “some people inside had guns” into “everyone there was a communist combatant.”
The same also applies to how the communists massacred innocent people. You keep focusing on a single event, when in fact it was a continuous event where TU students were caught red-handed carrying communist books during a time when the majority considered communism evil.
Why apply today's mindset to judge the past? It’s clear that there is a political agenda from the same old political groups.
It's not about applying today's mindset to the past, it's about holding the government to standards that any government should of any time should be expected to uphold. Don't indiscriminately kill civilians.
Out of fear communism would radicalize the students they attacked. Students fearing for their lives after seeing their fellow students being killed and tortured had to flee into the border jungles.
And no, it wasn't difficult to join those groups, there are thousands of accounts of the CPT just walking into rural border villages and asking the disfranchised locals to join them.
Yes there was distrust, the CPT command didn't trust the new members or the local villagers but that didn't stop them from taking them in and training them.
It's difficult to make stuff up considering that many folks accepted the amnesty and some of those later became high ranking officials and shared their stories. Phumtham being the most famous one, and he has given plenty of interviews describing his experience which are interesting to read or listen to.
This was a continuous chain of events. At the time, there was no internet, and newspapers were the major source of information. A news report emerged about TU students performing a play that depicted a hanging of a man who looked similar to the Crown Prince. This made people furious. The students who fled were killed not only by officials, but also by citizens who hated communists.
See? It was a continuous event. And they always have an excuse. For example: 'No, the hanging in the show was just a play about two men who were killed after protesting against Thanom'; 'Carrying communist books? No, the police scapegoated us'; 'Joining communist base camps? No, we never supported communists before October 6, but after the incident, we had no other choice,' blah blah. That's why I ask: How did they know who to contact to join the communist bases?
And how do you know the play was really about hanging the crown prince instead of about a dramatisation of the hanging of the protesters who protested against Thanom, and that the event totally wasn't distorted and blown out of proportion by a newspaper that want to sensationalize things, as many sources state?
And being a non law enforcement or military citizen doesn't change anything. If they took part in the massacre they're guilty simple as.
How did they know who to contact to join the communist bases?
Local communist party leaders, underground communist networks, askig around in local villages, walk into the jungle and hope the communists find you before the army does.
I don't see the relevancy of your question. You are trying to claim it was justified because those that survived went into hiding in the border jungle but that's not relevant to those who were murdered on a university campus.
We have accounts of students who were politically active but not communists and ended up joining after seeing their juniors being hung and desecrated because it was their only path forward for survival. There's no doubt there were communists with ties to the insurgency movement among the protesters, no one is denying that but that still doesn't justify the cruel and genuinely disturbing acts they did to the protestors.
How did you know who supported communism? You gave the same example and the same excuse-that October 6 forced them to join the communist bases-when Somsak Jeamteerasakul already admitted that it was always about communism.
Somsak Jeamteerasakul, a student leader and spokesperson during the rally at Thammasat University's Tha Phra Chan campus on October 6, 1976, posted on Facebook: “Back on October 6, 1976, we weren’t calling for democracy. That wasn’t the point. At the core of it all, our ultimate goal was Maoism - nobody’s buying into this ideology anymore."
It's another possibility, no one knows for sure. Maybe the current Thailand is the best option already. The difference between illusions of democratic and being red is very thin.
