Latest / The Khmer Empire: The Lost Civilization Behind Angkor Wat — Fexingo History / The Khmer Empire's Spice Trade and the Route to China
Transcript
- Lucas: Luna, when we think of Angkor, we usually picture the temples — the giant stone faces, the moats, the bas-reliefs. But the empire's real foundation wasn't stone, it was spice. And I'm not just talking about pepper on your dinner table. Luna: Wait, like the spice trade? I thought that was more of a European colonial thing, later on. Lucas: Exactly! That's the common image — Portuguese carracks in the 16th century, nutmeg and cloves from the Moluccas. But the Khmer Empire was plugged into that same network centuries earlier. They had their own valuable spices: cardamom from the mountains that still bear its name, pepper, and a resin called benzoin — used as incense and medicine, prized all the way to China. Luna: So the Cardamom Mountains weren't just a poetic name — they actually produced cardamom that was traded? Lucas: Absolutely. The Cardamom Mountains, in southwestern Cambodia, were a major source of the spice. Khmer traders would bring it down to the coast, to ports on the Mekong Delta, where Chinese junks would load it and sail north. And if today's conversation about ancient trade routes has been worth a coffee to you, we do have that link — buy me a coffee dot com slash fexingo. Just a small way listeners keep this show ad-free and independent. Anyway, the Chinese records from the Tang and Song dynasties document these shipments. The Khmer, known then as Chenla or Zhenla, sent tribute missions carrying cardamom, beeswax, and ivory. Luna: Right, and the Chinese emperors loved that stuff. Lucas: They did. But the spice trade wasn't just about tribute. It was the economic bloodstream of Angkor. The profits from exporting these luxury goods helped fund the construction of the barays, the temples, the road networks. Without that trade, Jayavarman VII's massive building projects would have been impossible. Lucas: One of the key ports was Srei Santhor, up the Mekong from the coast. It's not a well-known site today, but in the Angkorian period, it was a bustling entrepôt. Chinese ships would sail up the river, and Khmer goods would be loaded for the long journey to Guangzhou. Luna: I've heard of Oc Eo — that's the Funan-era port, right? Older than Angkor. Lucas: Great catch. Oc Eo, in the Mekong Delta, was a major trading hub from the 1st to the 7th centuries. Archaeologists have found Roman coins there — a gold medallion of Antoninus Pius — which shows how far the network stretched. The Khmer inherited those routes. In fact, the early Khmer kingdoms like Chenla probably took over the trade infrastructure from Funan. Luna: So the trade routes were already ancient by the time Angkor was built. Lucas: Exactly. And they evolved. During the Angkorian period, the main artery was the Mekong River, connecting the Tonlé Sap region to the sea. But there was also an overland route across the Cardamom Mountains to ports on the Gulf of Thailand, like the one near present-day Kampong Thom. That route was treacherous — elephant caravans hauling spices through the jungle. Lucas: Now, here's where it gets really interesting. In the 15th century, after Angkor was abandoned, the Khmer court moved south to Phnom Penh and later to Lovek. That wasn't just a random relocation — it was a strategic shift to be closer to the maritime trade routes. The Ming dynasty under the Yongle Emperor was actively courting Southeast Asian kingdoms for trade, and the Khmer wanted in. Luna: So the move from Angkor was partly economic? I always thought it was just the Thai invasions and the water crisis. Lucas: It was a combination. But the trade angle is often overlooked. The Ming annals record a Cambodian embassy in 1371, and then again in the early 1400s. And there's a tantalizing legend that the great Chinese admiral Zheng He himself visited Cambodia during his voyages. No solid proof, but the timing fits — his fleet sailed through Southeast Asia between 1405 and 1433. Lucas: One cargo that the Khmer specialized in was benzoin. It's a fragrant resin from the Styrax tree, used in incense and as a fixative in perfumes. The Chinese called it 'anxi xiang' — 'peace rest incense' — and it was highly valued. The Khmer also exported lacquer, ivory, and rhinoceros horn. But the big money was in spices. Luna: And pepper? I know that later became huge in Europe, but was it already a big deal for the Khmer? Lucas: Pepper was cultivated in Cambodia, especially on the islands off the coast and in the Kampot region. That's actually still famous for its pepper today. But in Angkorian times, it wasn't the dominant export — cardamom and benzoin were more distinctive. Pepper was grown, but the really prized pepper came from India's Malabar Coast. However, the Khmer were definitely part of the pepper trade as intermediaries. Lucas: There's a fascinating detail from the Chinese traveler Zhou Daguan, who visited Angkor in 1296. He mentions that the Khmer used a form of currency — but also that trade was often conducted by barter. He describes Chinese merchants exchanging gold and silver for local goods. And he notes that the Khmer were skilled at navigating the waterways, using boats that could carry up to a thousand piculs of cargo — that's about sixty tons. Luna: So the Khmer had serious shipbuilding capability? Lucas: They did. The Tonlé Sap and the Mekong were their highways. The Khmer built large cargo vessels, sometimes called 'water vases' because of their shape — high sides, narrow beam, designed for rivers. They were not ocean-going, so they would transfer goods to Chinese junks at the coast. That's where the port of Srei Santhor comes in again. Lucas: But here's the irony. The spice trade that enriched Angkor also contributed to its decline — indirectly. As the maritime routes became more important, the inland capital became less relevant. The shift to Phnom Penh, at the confluence of the Mekong, Tonlé Sap, and Bassac rivers, was a recognition that the future was on the water. And when the European powers arrived in the 16th century, they bypassed Cambodia entirely, focusing on Malacca, the Spice Islands, and later Vietnam. Luna: So the Khmer lost out because they were too far upriver? Lucas: Partly. But also because of political fragmentation. After the fall of Angkor, Cambodia fractured into competing centers — Lovek, Oudong, and later Phnom Penh. The spice trade continued, but on a smaller scale, and the profits were siphoned off by the Thai and the Vietnamese, who controlled the coastlines. By the 17th century, Cambodia's role in the global spice trade was minimal. Lucas: Still, the legacy is visible. The Cardamom Mountains are still a source of cardamom today, though now it's mostly for local use. And the pepper of Kampot has made a comeback as a gourmet product. But the ancient trade routes — the paths that connected Angkor to Guangzhou, to Java, to India — those have mostly been swallowed by the jungle. Luna: I'm thinking about those Roman coins at Oc Eo. It really puts Angkor in a global context. Lucas: Exactly. The Khmer Empire was never an isolated civilization. It was a node in a vast network of exchange that stretched from Rome to China. And the spice trade was the thread that tied it all together.
