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.
