Latest / Trade Routes That Changed Human History Forever — Fexingo History / The Taiping S: How Baghdad's Trade with China Shaped the World
Transcript
- Lucas: So we've talked a lot about the Silk Road over land, those caravans crossing Central Asia. But there was a whole other Silk Road, just as important, that went by sea. And in the eighth century, it connected two of the world's biggest economies, Baghdad and Chang'an. That's what I want to get into today. Luna: Oh, the maritime one. I've heard of it, but it feels less famous than the overland routes. Lucas: Exactly. And part of the reason is because the sea route left fewer monuments, but the trade was huge. Think about it, the Abbasid caliphate under Harun al-Rashid, and the Tang dynasty at its peak, they were like two giant magnets pulling goods and ideas across the Indian Ocean. Lucas: Now, the key to this whole thing was the monsoon winds. Sailors had figured out that you could ride the southwest monsoon from Arabia to India, and then the northeast monsoon back. It made the voyage predictable, almost like a seasonal highway. And at the heart of this network was the port of Siraf, on the Persian Gulf coast of what's now Iran. Luna: Siraf. That's a name I don't hear often. What was it like? Lucas: It was one of the richest ports of its time, a staging ground for ships heading to India and beyond. The houses were built of teak and imported stone, several stories high, with courtyards and gardens. There were mosques, bazaars, warehouses. And the merchants there dealt in everything from frankincense to Chinese ceramics. Lucas: One of the best pieces of evidence we have for this trade is the Belitung shipwreck, found off the coast of Indonesia, dated to around 826. It was an Arab dhow, packed with over sixty thousand items, mostly Changsha bowls, those green-glazed ceramics from Hunan. And it had gold and silver artifacts, too. That ship was probably heading from China back to the Persian Gulf. Luna: Wow, sixty thousand bowls? That's a serious cargo. Lucas: It really shows the scale. And what's interesting is that the ship itself was built in the Arab style, using coconut fiber stitching, not nails. So it's proof that Arab shipbuilders were active in Southeast Asian waters, integrating with local shipwrights. The cargo tells us about demand, but the ship tells us about technology transfer. Lucas: But there's also a written source that gives us a window into this world, and it's called the Taiping S. It's an eighth-century Chinese manual for sailors, essentially a guide to the maritime routes to the Persian Gulf. It describes the ports, the distances, the dangers. It's like a pilot's handbook for that era. Luna: A Chinese guide to the Indian Ocean routes? That's fascinating. Who wrote it? Lucas: We don't know the author, but it was compiled during the Tang dynasty, probably around the time of the An Lushan rebellion. It was meant for Chinese merchants who were venturing west by sea, telling them things like how many days it took to get from Guangzhou to Palembang, or from Palembang to the Malabar coast, and finally to Siraf. Lucas: And it's not just a list of directions. It includes practical details, like what to bring for trade, how to deal with local rulers, and where to expect pirates. It's a really grounded, practical document, and it shows that by the eighth century, the sea routes were so established that people were writing manuals for them. Luna: So the sea route was just as organized as the land caravans, if not more. Lucas: Absolutely. And there's a personal story from this time that brings it home. His name was Du Huan, and he was a Chinese soldier who was captured during the Battle of Talas in 751, when the Tang army fought the Abbasids and their allies. He ended up in Baghdad, and he spent about a decade traveling in the Middle East and North Africa before he found his way back to China. Lucas: Du Huan wrote a book about his experiences, the Jingxingji, and it's one of the few first-hand accounts we have from a Chinese person living in the Islamic world at that time. He described the markets, the food, the customs, even the glassmaking and papermaking techniques he saw. It's a remarkable document of cultural exchange. Luna: That's incredible. He went from being a prisoner to a kind of accidental traveler. Lucas: Exactly. And his account is full of details, like how the people of Baghdad bathed regularly, which he found notable, or how they used water clocks. He also mentioned that he saw Chinese papermakers working in Samarkand, which is one of the clues about how paper technology spread westward. Lucas: But the trade wasn't just between the caliphate and China. There were other players, like the Silla kingdom in Korea, which was importing Chinese goods and also acting as a middleman for Japanese trade. And there were the Radanites, those Jewish merchants we talked about before, who connected the Mediterranean to the Indian Ocean through land and sea routes. Luna: So it's a whole web of connections, not just a simple two-way street. Lucas: Right. And the Cairo Geniza, that trove of documents from a synagogue in Cairo, gives us actual letters from Jewish merchants in the eleventh century, talking about shipments of spices, textiles, and even paper. It shows how these networks persisted and adapted over centuries, long after the Abbasid golden age had faded. Lucas: But even before that, in the eighth and ninth centuries, the volume of trade was staggering. Chinese writers of the time, like Jia Dan, described the route in detail. And Arab geographers like Ibn Khordadbeh, who wrote the Book of Roads and Kingdoms, listed the ports and distances along the same route, sometimes matching the Chinese accounts almost perfectly. Luna: So both sides were keeping records. That's how we know so much. Lucas: Yes. And when you add the archaeological evidence, like the Belitung wreck, it all lines up. We know the ships, the goods, the ports, the people. It's a rich picture of a world that was much more interconnected than we often imagine. Lucas: There's something about this that I find really moving, though. These were people who risked their lives, who spent months at sea, just to bring things like porcelain and silk from one side of the world to the other. And they did it regularly, for centuries. That kind of sustained exchange is what built the foundations of our modern global economy. Luna: It's easy to forget that before the Europeans sailed in, the Indian Ocean was already a busy place. Lucas: Exactly. And that's why when we talk about Vasco da Gama and the Portuguese, we have to remember that they were entering an ocean that already had established routes, established ports, established relationships. They weren't discovering anything new, they were inserting themselves into an ancient network. Lucas: It's also worth noting that this maritime trade was not just about goods. It was about ideas, technologies, and art. Chinese papermaking, Arab astronomy, Indian mathematics, all of these traveled along these routes. The world we live in is a product of those exchanges, as much as any empire or kingdom. Luna: And you know, thinking about how much we rely on global trade now, it's humbling to see it all started so long ago. Lucas: Yeah. And I think that's part of why we do this show, to uncover those connections. And it reminds me, we keep the show ad-free because we believe in telling these stories without interrupting them. If you'd like to support that, you can find us at buy me a coffee dot com slash fexingo. No pressure, but it does help. Luna: Yeah, a coffee for Lucas, a coffee for history. It's a nice way to keep this going. Lucas: So, back to the Taiping S. One of the things I love about it is how it talks about the different ports and their specialties. For example, it mentions that in Palembang, you could get spices and gold, and in Kedah, on the Malay Peninsula, you could find tin and aromatic woods. It's like a shopping guide for the eighth-century trader. Luna: It's almost like reading a travel blog from a thousand years ago. Lucas: Exactly. And it also mentions the dangers, like the pirates in the Strait of Malacca, or the storms in the Bay of Bengal. The author gives practical advice, like which seasons to sail, and when to avoid the route altogether. It's a reminder that this trade was not for the faint of heart. Lucas: But despite the risks, the rewards were enormous. A successful voyage could make a merchant's fortune. And that attracted people from all over, not just Arabs and Chinese, but also Persians, Indians, Malays, and even some Greeks and Africans. The port of Siraf was a true cosmopolitan hub. Luna: So it was like a medieval melting pot. Lucas: It was. And you can see it in the archaeological finds from Siraf, which include Chinese ceramics, Thai glass, and Indian beads. The houses themselves were built with imported teak and stone, as I mentioned. The city was literally made of trade. Lucas: Eventually, though, Siraf declined. The port of Basra, further up the Gulf, became more important, and then Hormuz took over. But for a couple of centuries, it was the beating heart of the Indian Ocean trade. And the Taiping S, along with the Belitung wreck, helps us remember that. Luna: It's amazing how much we can learn from a few artifacts and a manual. Lucas: It's a good reminder that history isn't just about kings and battles. It's also about the everyday people who moved the goods, the sailors, the merchants, the dockworkers. They're the ones who actually built the global economy, one voyage at a time. Lucas: So next time you use a piece of paper or drink a cup of tea, you can thank the monsoon winds and the people who rode them. Luna: I'll never look at a teabag the same way again.
