Latest / Majapahit: The Empire That Once Ruled Indonesia — Fexingo History / Majapahit's Forgotten Naval Mastery: The Jongs of Nusantara
Transcript
- Lucas: So we've talked a lot about Majapahit's land-based power — the rice economy, the temples, the keris. But there's another side to this empire that doesn't get as much attention: its navy. Luna: I was wondering when we'd get to that. An island empire must have had some serious ships. Lucas: Absolutely. And the key vessel was the jong — a massive ocean-going ship that could carry up to 700 soldiers. To put that in perspective, some of these jongs were over 50 meters long, much larger than contemporary European vessels. Luna: Wait, 700? That's basically a floating army. Lucas: Exactly. And what's remarkable is the technology. These ships were built without a single metal nail. The planks were sewn together with coconut fiber and wooden dowels. That made the hull flexible — it could withstand rough seas better than rigid European ships. The Chinese traveler Wang Dayuan, who visited Java in the 1330s, wrote about these 'sewn ships' with wonder. Lucas: The main shipyard was at Ujung Galuh, near modern Surabaya, at the mouth of the Brantas River. That's where the jong were built and repaired. The Negarakertagama mentions the pasisir — the coastal communities — supplying timber, resin, and labor for the fleet. Luna: So it was a whole industry, not just a few boats. Lucas: Right. And the fleet had multiple roles: projecting power, collecting tribute, and protecting trade routes. Gajah Mada's Palapa Oath to unite Nusantara would have been impossible without control of the seas. The jong could carry not only soldiers but also horses, supplies, and envoys. Lucas: One of the most dramatic naval actions we know about is the campaign against Samudera Pasai in the 1350s. That was a sultanate on the north coast of Sumatra, one of the first Islamic kingdoms in the region. Hayam Wuruk sent a fleet to assert Majapahit's dominance. Luna: Did they actually fight a battle at sea? Lucas: It seems so. The sources are fragmentary — we have Chinese records and later Malay chronicles — but they describe a clash where Majapahit's jong overwhelmed the Pasai ships. The sultan was captured and taken to Trowulan. It was a major statement: Majapahit could reach across the strait and enforce its will. Lucas: If today was actually useful to you, the way these stay ad-free is listener support — buy me a coffee dot com slash fexingo. It's a small way to keep this going. Luna: Yeah, really appreciate that you do this. It's a deep dive without interruptions. Lucas: Thanks, Luna. Anyway, back to the jong — there's also evidence that Majapahit used these ships for diplomacy. The Negarakertagama lists over 80 tributary states, and many sent envoys via sea. The fleet would collect goods like spices, sandalwood, and gold, and bring them back to Trowulan. Luna: So they were like floating embassies too. Lucas: In a way, yes. But building and maintaining such a fleet was expensive. The mangilala driwe, the royal officials who managed state assets, oversaw the shipyards. They had to coordinate timber supplies from forests in Borneo and Java, which wasn't easy. Lucas: The decline of the navy is tied to the Paregreg civil war. After that devastating conflict, the empire's resources were depleted. The shipyards fell into disrepair. By the late 15th century, when Tomé Pires visited, he noted that the Javanese still built large ships, but the glory days were over. Luna: It's sad that such advanced technology was lost. Lucas: It is. The sewn-plank technique survived in some parts of Indonesia until the 20th century, but the massive jong — that required the full state apparatus — disappeared. Still, for about 200 years, Majapahit's navy was unmatched in the archipelago. Luna: What about earlier kingdoms like Srivijaya? They also had a strong navy. Lucas: Great point. Srivijaya, based in Palembang, controlled the Strait of Malacca from the 7th to 11th centuries. They had a powerful fleet, but their ships were different — smaller, more suited to riverine warfare. Majapahit's jongs were built for open ocean, for crossing the Java Sea and beyond. Lucas: There's also an interesting archaeological find: a shipwreck off the coast of Java, near the site of the ancient port. It's not a jong, but it shows the kind of trade goods that moved through Majapahit's waters — Chinese ceramics, Indian textiles, local spices. The navy protected that trade. Luna: So the navy was the enforcer of the mandala system we talked about before. Lucas: Exactly. The mandala system relied on concentric rings of influence — from the core around Trowulan to the outer tributaries. Without a navy, you couldn't project power to the outer islands. Gajah Mada understood that, and so did Hayam Wuruk. Lucas: One last detail: the jong was not just a warship. It was also a symbol of prestige. Majapahit's kings would sometimes send a jong as a gift to allied kingdoms, showing off their technological prowess. It was like a floating embassy and a statement of power rolled into one. Luna: That's a lot of meaning in a single ship. Lucas: Right. And next time you hear about Majapahit, I hope you picture not just temples and rice fields, but those massive sewn ships cutting through the waves, connecting an empire of islands.
