On the 17th of April, 1975, the Khmer Rouge took Phnom Penh. By midday they were emptying it. Two million people were marched out of the city at gunpoint, told the Americans were about to bomb, and that they could come home in three days. Phnom Penh stayed almost empty for the next four years.

How would you react to being forced out of your home at gunpoint, ordered to leave everything behind, and told to walk for days into the countryside toward a fate nobody would explain? And that was only the beginning.

Time period covered: 1969–1979

This first episode covers the fall of Phnom Penh, the evacuation of the city, and the discovery of the S-21 prison by the Vietnamese army in January 1979. It includes the recollections of Jim Laurie, Elizabeth Becker, Al Rockoff and Dith Pran, who were there. Under the Khmer Rouge, something like one in five Cambodians died in under four years. This series is a detailed narrative history of Cambodia and an attempt to explain how that happened. This episode is an introduction to the events themselves, before the series goes back to the beginning of Cambodian history to work out why.

Re-recorded and expanded in 2026.

Who are the Khmer people, and where did they come from?

Why does almost everything written about early Cambodia need to be revised?

Time period covered: Pre-history – 850 CE

In this episode, Lachlan introduces the landscape, the people, and the deep history of the Khmer civilisation before the era of god-kings. The monsoon cycle that defines everything. The animist world of spirits and sacred hills that underlies all the religions that come later. We examine what archaeology and inscriptions actually tell us about the pre-Angkorean period, and why the old frameworks of Funan and Chenla (borrowed from Chinese chronicles and repeated for a century) don't quite hold up. The episode ends on Phnom Kulen, the sacred mountain, where Jayavarman II performs a ceremony declaring him the universal monarch: Devaraja.

How do you build the largest city in the medieval world? What does it actually take to construct Angkor Wat? And what happens when the greatest king in Khmer history dies and leaves an empire stretched to its limits?

Time period covered: 802 – 1296 CE

In this episode, Lachlan traces the rise of the Khmer Empire from Jayavarman II's ceremony on Phnom Kulen to the death of Jayavarman VII, the most prolific builder in Angkorean history. The three-step blueprint of the early kings — waterworks, ancestral temple, state temple. The building of Yasodharapura and the East Baray. The interlude at Koh Ker and why it failed. The mystery of Suryavarman I's blood oath and the patronage networks that held the empire together.

We cover Suryavarman II and the construction of Angkor Wat in detail — the labour, the materials, the corbelled architecture, the astronomical alignments, and the sheer organisational achievement of moving and placing millions of tonnes of stone. Then Jayavarman VII: the Cham sacking, the comeback, the building programme that outstripped every king before him combined, and the contradiction at the heart of his reign between compassion and extraction.

What was Angkor actually like to walk through? What really happened to the Khmer Empire, and why is the standard version wrong? Was Angkor ever actually "lost"?

Time Period Covered: 1296 – 1600 CE

In 1296, a Chinese diplomat named Zhou Daguan stepped off a boat at Angkor, stayed eleven months, and wrote down what he saw — the palace, the markets, the food, the gossip. His account is the only surviving eyewitness description of the city at its height. A century and a half later the capital moved south, and Europeans would eventually decide the city had been 'lost'. It hadn't, and what actually happened took the better part of a century of new science to work out.

After Angkor was abandoned, the Khmer court moved south to the Mekong and spent the next four centuries surviving. By the eighteenth century, Cambodian kings were being installed and removed by Bangkok or Hue, and sometimes paying tribute to both at once. This is the part of Cambodian history that almost nobody covers, and it sets the terms for everything that follows.

Time Period Covered: 1431 – 1800

How did the Khmer go from a civilisation which dominated most of mainland Southeast Asia to a reduced vassal state of either the Siamese or the Vietnamese? Why did the capital move from Angkor? And why are the Vietnamese the 'hereditary enemy' of the Khmer?

In this episode, Lachlan covers the 'middle period' or 'dark ages' — the move south, the courts at Longvek and Oudong, and the slow closing of the vice between Siam to the west and Vietnam to the east.

The second half is a brief history of Vietnam: the long march south, the Trinh and the Nguyen, and a political culture built on entirely different foundations to the Khmer one. This eastern neighbour plays a vital role in the story of the region in the 20th century, and no history of the Khmer Rouge works without it.

In the 1590s a Spaniard and a Portuguese, Blas Ruiz and Diogo Veloso, arrived in Cambodia and came close to taking the country over. It ended in a massacre and a farce, and it was Europe's first serious attempt at the place. The next one, two centuries later, worked.

Time Period Covered: 1500 – 1825

How will the forces of imperialism and colonialism come to the region of Indochina? What role will Europeans play in shaping what will eventually become the state of Cambodia?

In this episode, Lachlan relays the ridiculous story of Ruiz and Veloso, and spends some time on what the larger forces of colonialism looked like around the globe at this time.

The attention then shifts to France. The story of Pigneau de Béhaine, a French missionary stationed in Vietnam, sets up the long and tangential relationship between Vietnam and France — the conflict inside Vietnam, and the eventual unification of the kingdom under Emperor Gia Long with the missionary's help. The episode ends with 'the master's tea', the infamous Cambodian folktale about Vietnamese cruelty to the Khmer that can still be heard today.

Alex Hinton Why Did They Kill?

If you have read one book about Cambodia, there is a good chance David Chandler wrote it. A History of Cambodia has been the standard introduction for four decades, Brother Number One remains the essential biography of Pol Pot, and Voices from S-21 is the definitive study of the Khmer Rouge's central prison. He has testified twice as an expert witness at the Khmer Rouge Tribunal, against Duch in Case 001, and against Nuon Chea and Khieu Samphan in Case 002/01.

I had the privilege of sitting down with Professor Chandler at his home in Melbourne to discuss the current state of Khmer Rouge historiography, his thoughts on the tribunal, whether the crimes of the Communist Party of Kampuchea can properly be called genocide, and his experience of visiting the country in 1981, so soon after it reopened to the outside world.

David was Professor Emeritus at Monash University, where I first met him in 2011.
