Latest / The Khmer Empire: The Lost Civilization Behind Angkor Wat — Fexingo History / Mahendravarman: The Khmer King Who Sailed to Champa
Transcript
- Lucas: Luna, I want to take us back — way before Angkor Wat, before Suryavarman II, before any of the names we've spent so many episodes on. There's a period that most people skip over, but it's where everything really started. The Chenla period, roughly the 6th to 8th centuries. And there's one figure from that time who I think is absolutely fascinating: a king named Mahendravarman. Luna: Mahendravarman — I don't think we've mentioned him before. What's his story? Lucas: He ruled what historians sometimes call 'Water Chenla' — the southern part of the Mekong delta, a region of rivers, canals, and floating villages. But what makes him stand out is that around 600 CE, he did something unusual: he sailed east, across the South China Sea, to the kingdom of Champa. Not to invade — to study. Luna: Wait — a Khmer king went to Champa as a student? Lucas: Exactly. This is a century before the big Cham invasions we talked about in episode 58. At this point, Champa was the older, more sophisticated civilization — they had been trading with India and China for centuries, they had Sanskrit inscriptions, brick temples, a whole courtly culture. Mahendravarman wanted to bring that knowledge back home. And he did. Luna: So he was like an early diplomat, or a scholar-king? Lucas: Both. He spent time at the Cham court, probably in the region of modern-day Da Nang or Quy Nhon. He observed their administration, their religious rituals, their architecture. Then he returned to Chenla and built some of the earliest surviving stone temples in the Khmer world. Two of them — Phnom Da and Asram Maha Rosei — still stand today, small but incredibly significant. Luna: I've seen photos of Phnom Da — it's this little hilltop temple near the Mekong, right? Very different from Angkor Wat. Lucas: Completely different. Phnom Da is a single brick sanctuary on a natural hill, with a simple, almost austere design. But the inscription there — it's in Sanskrit, and it tells us that Mahendravarman installed a linga, the symbol of Shiva. That's the earliest known linga installation in the Khmer region. It's a direct link to the later devaraja cult, the whole idea of the god-king. But here, it's still personal, not state ideology. Luna: So the devaraja tradition didn't start with Jayavarman II on Phnom Kulen — it had roots going back a couple hundred years. Lucas: Exactly right. Jayavarman II formalised it, but the elements were already there. Mahendravarman's inscription also mentions a sraddha — a ritual offering to ancestors. So you have this blend of Cham-influenced Shaivism and indigenous ancestor worship. That fusion becomes the core of Khmer religion. Luna: What about the other temple — Asram Maha Rosei? That name sounds almost hermitage-like. Lucas: It means 'hermitage of the great sage' in Sanskrit. It's even smaller than Phnom Da, a single brick cell, but it's beautifully proportioned. The inscription there is longer — it records Mahendravarman's genealogy and his achievements. He calls himself 'the sole lord of the earth' — a pretty bold claim for a king of a relatively small delta kingdom. But he's laying the groundwork for the imperial rhetoric of later Khmer kings. Luna: So these two temples are like the prototype for everything that came later. Lucas: In a way, yes. And here's something that connects directly to our earlier episodes: Mahendravarman's predecessor — possibly his father — was a king named Bhavavarman I. Bhavavarman is the one who really united Chenla and expanded it. He conquered the earlier kingdom of Funan, which had dominated the region for centuries. So you have this transition: Funan, which was a maritime trading empire, gives way to Chenla, which is more agrarian and inland-focused. And Chenla in turn gives way to the Khmer Empire of Angkor. Luna: I'd love to dig into Funan more someday. But for now — Mahendravarman's trip to Champa — was that a one-time thing, or did Khmer-Cham relations stay peaceful after that? Lucas: Unfortunately, it didn't stay peaceful. Within a couple of generations, Chenla and Champa were fighting over territory. And by the 9th century, the Khmer kings were launching raids into Champa. But that initial contact was foundational. The Cham taught the Khmers how to build in brick and stone, how to organize a court, how to write Sanskrit poetry. Without Mahendravarman's voyage, Angkor Wat might have looked very different. Luna: It's amazing to think that a single journey could shape an entire civilization's trajectory. Lucas: And that's really what I love about this period — it's not a story of inevitable greatness. It's a story of choices, of learning, of borrowing and adapting. Mahendravarman could have stayed home. But he didn't. He went, he saw, he brought back ideas. And those ideas, brick by brick, became Angkor. Luna: You know, hearing that — it makes me realise how much this show depends on that same spirit of curiosity. Just people sharing what they've learned, because they find it genuinely interesting. Lucas: That's a really nice way to put it. And honestly, that's why we keep doing this — and why we keep it ad-free. If today's episode was useful to you, the way these stay free is listener support. You can find us at buy me a coffee dot com slash fexingo. No pressure, just a way to keep the conversation going. Luna: Yeah, it really does help. And speaking of going further — Mahendravarman's story doesn't end with those two temples. What happened to Chenla after him? Lucas: Good question. After Mahendravarman, Chenla eventually split into two — Water Chenla and Land Chenla. Water Chenla was along the Mekong delta and Tonle Sap, Land Chenla was further inland, in what is now Laos and northeastern Thailand. But both were overshadowed by the rise of the Angkorian empire under Jayavarman II in the early 9th century. Still, the Chenla period left behind a rich legacy of inscriptions and early temple foundations. And one of the most important sites from that era is Isanapura — the capital of a later Chenla king, Isanavarman I. Luna: Isanapura — that's the site of Sambor Prei Kuk, right? I've heard that name. Lucas: Yes, exactly. Sambor Prei Kuk, which means 'temple in the richness of the forest' in Khmer. It's a huge complex of over a hundred temples, mostly brick, with amazing octagonal towers and intricate lintel carvings. It was built in the early 7th century, around 620 CE, by Isanavarman I. And it's one of the best surviving examples of pre-Angkorian architecture. The site is massive — it covers several square kilometers — and it gives us a real sense of the scale of Chenla's ambitions. Luna: So Chenla wasn't just a minor precursor — it was a major kingdom in its own right. Lucas: Absolutely. Isanapura had a moat, a wall, a central sanctuary, and dozens of smaller shrines. The art style is distinctive — it's sometimes called the 'Sambor style' — with a strong Indian influence but also local elements. You see depictions of Vishnu, Shiva, but also of local deities. And the inscriptions are in Sanskrit and Old Khmer. So you have this bilingual culture emerging, which becomes the norm under the Khmer Empire. Luna: Did Isanavarman also have contact with Champa? Lucas: He did, but it was more hostile. There's an inscription from Isanapura that mentions a Cham king being defeated and brought back as a captive. So the relationship had soured. But the cultural borrowing continued. The Cham influence on Khmer architecture is still visible at Sambor Prei Kuk — the brick towers, the false doors, the pilasters — all techniques the Khmers learned from the Cham. And then later, the Khmers surpassed their teachers. Luna: It's like a cycle: first you learn from your neighbor, then you compete, then you eclipse them. Lucas: That's a great way to sum it up. And the irony is that by the time Angkor Wat was built, the Cham were no longer seen as teachers but as enemies. Yet without that early exchange, there might not have been an Angkor Wat at all. That's the kind of historical irony I love. Luna: So what happened to Chenla itself? Why did it disappear from history? Lucas: Chenla didn't exactly disappear — it transformed. By the late 8th century, the kingdom fragmented. There are records of a 'king of the Khmers' around 800, but he's a shadowy figure. Then Jayavarman II appears, claiming independence from a Javanese overlord — that's the famous 'devaraja' inauguration on Phnom Kulen in 802. He unified the Khmer principalities and founded the Angkorian empire. So Chenla was the seed, but Angkor was the tree. Luna: And the seed is often forgotten. I'm glad we're giving it some attention. Lucas: Me too. Because when you look at those early brick temples — Phnom Da, Asram Maha Rosei, Sambor Prei Kuk — you can see the beginnings of everything that made Angkor great: the hydraulic engineering, the temple-mountain concept, the Sanskrit inscriptions, the Hindu-Buddhist synthesis. It's all there, just in miniature. Luna: Do any of those sites still have active worship, or are they purely archaeological? Lucas: A few of them do. Phnom Da, for instance, is still used by local villagers for small ceremonies. There's a newer Buddhist pagoda next to it. And at Sambor Prei Kuk, some of the temples are considered sacred by the surrounding communities. But mostly, they're quiet, forested ruins — visited by a handful of tourists and archaeologists. They don't have the crowds of Angkor Wat, which makes them even more special in a way. Luna: I'd love to visit one day. Just to stand where Mahendravarman stood. Lucas: It's a powerful feeling. And when you do, you'll notice something: the bricks at Phnom Da are laid without mortar. They're so precisely cut that they fit together perfectly, using a kind of organic adhesive — maybe plant resin. That technique is distinctly Cham. So even the walls are telling a story of cultural exchange. Luna: Every brick has a story. I think that's a good note to end on. Lucas: I think so too. Thanks for exploring the deep roots of Angkor with me. Next time, we'll jump forward to a topic that's been on my mind — the role of the Tonle Sap lake in Khmer cosmology and daily life. Until then, keep questioning.
