- Lucas: So we've talked a lot about Majapahit's grand temples, its royal succession, its sacred blades. But there's something else that made the whole thing work, something you don't see in the stone reliefs as much: water. Luna: Water? Like irrigation for the rice terraces? Lucas: Partly, but more than that. I'm talking about canals. A whole network of artificial waterways that connected the capital Trowulan to the Brantas River and the north coast. These were the empire's arteries. Luna: Huh. I've walked through Trowulan and seen some of those dry channels, but I never thought of them as a system. Lucas: Right. And if today's episode gives you a new way to picture that landscape — those canals as busy highways of rice, spices, and timber — then I'll be happy. If you find that useful, you know, the way we keep these shows ad-free is through listener support at buy me a coffee dot com slash fexingo. It's a small thing that lets us keep digging into these stories without any commercial breaks. Anyway, back to the canals. Luna: Yeah, I want to hear more about how they actually built them. Lucas: So the Brantas River delta is flat, fertile, but prone to flooding. Majapahit engineers — and we don't know their names, unfortunately — they dug canals to divert water from the river into a grid of channels. Some of these channels are still visible in the dry season around Trowulan. The Negarakertagama, Mpu Prapanca's poem from 1365, mentions the king traveling by boat along these waterways. It was a way to move goods efficiently without relying on oxcarts. Luna: Wait, so they had boat traffic right through the capital? Lucas: Exactly. The canals weren't just for irrigation. They were transport corridors. Imagine rice from the hinterlands loaded onto small boats, poled through the canals to Trowulan's markets, and then transferred to larger vessels on the Brantas for export to the pasisir ports like Tuban or Gresik. It was a multimodal system — river, canal, sea. Luna: So the canals basically replaced roads. Were they like, paved or lined with stone? Lucas: Some sections were lined with stone, yes, especially near important structures. But most were just earthen channels, maybe reinforced with bamboo. The real engineering feat was managing the gradient. The Brantas carries a lot of silt, so canals would silt up quickly. They must have had regular dredging crews. Luna: That sounds like a huge labor investment. Lucas: It was. But when you consider that rice — wet rice, grown in sawah — requires precise water control, it makes sense. The canals doubled as irrigation for the fields. And there's evidence of larger reservoirs too. Candi Tikus, which we've mentioned before, is often interpreted as a water temple — a bathing place, yes, but also part of a larger hydraulic system. It had a network of pipes and channels feeding into the surrounding area. Luna: I've seen photos of Candi Tikus — it's like a miniature mountain with all those spires. But I never connected it to water management. Lucas: That's the thing about Majapahit: religion and infrastructure are intertwined. The king had a duty to maintain order — cosmic and practical. Keeping the canals flowing was part of that dharma. The Sengkala Memet inscription from the late 14th century mentions a royal decree about water rights, allocating shares of a river to different villages. So there was a legal framework too. Luna: Water rights in the 1300s — that's sophisticated. Lucas: Absolutely. And when the empire started to decline in the 15th century, one theory is that the canals fell into disrepair. Without central maintenance, siltation and flooding would have disrupted rice production and trade. The pasisir ports, which had grown rich, began to assert independence. So the water system is tied to Majapahit's political trajectory. Luna: So the canals were a kind of hidden backbone. Without them, the whole thing crumbles. Lucas: Exactly. It's a reminder that empires aren't just built on battles and oaths. They're built on mud, water, and the daily labor of keeping channels clear. And the legacy of those canals? Later Javanese kingdoms like Mataram also relied on hydraulic engineering. The Dutch colonial system too — they just took over and modified existing infrastructure. Luna: That's fascinating. So next time I'm in Trowulan, I'll be looking at those dry ditches differently. Lucas: And maybe you'll imagine a little boat loaded with rice, gliding past the brick gates. Thanks for coming along on that journey.
