- Lucas: So we've spent a lot of time on the Atlantic — the ships, the Middle Passage, the plantations. But there was another ocean where people were bought and sold for centuries, and it ran parallel to everything we've talked about. Luna: The Indian Ocean, right? We touched on it a bit in the episode about that shipwreck. Lucas: Exactly. The São José wreck — that was a ship carrying captives from Mozambique to the Americas. But the Indian Ocean trade was much older and in some ways just as brutal, if not more so in terms of the numbers of women and children involved. Lucas: Think about the Swahili Coast — that stretch of East Africa from Somalia down to Mozambique. For over a thousand years, city-states like Kilwa and Mombasa were hubs for trade, and one of the main commodities was human beings. Luna: So the trade was already there before the Europeans showed up? Lucas: Oh, absolutely. The Indian Ocean slave trade predates the Atlantic by centuries. Arab and Persian traders were moving captives from East Africa to the Middle East, India, and even China. The scale was smaller than the Atlantic at its peak, but it was constant and it shaped the whole region. Lucas: And here's the thing — the demand wasn't for plantation labor, at least not at first. It was for domestic servants, soldiers, concubines, and eunuchs. That's a different kind of slavery, but it's still slavery, and it's often overlooked in Western history. Luna: That's a big difference. So the experience of an enslaved person there would have been quite different from someone on a sugar plantation in the Caribbean. Lucas: Yes, and the demographics were different too. In the Indian Ocean trade, a larger proportion were women and children. That's partly because the demand was for domestic and sexual labor, but also because men were often kept in East Africa for other purposes, like caravan porters. Lucas: Now, when the Portuguese arrived in the sixteenth century, they didn't create the trade — they plugged into it. They used the existing networks to export captives to their colonies in the Atlantic, and also to work on their own sugar plantations in São Tomé and later in Brazil. Luna: So the Atlantic and Indian Ocean trades were connected from the start. Lucas: They were, and they only became more entangled over time. In the nineteenth century, the demand for plantation labor in the Indian Ocean islands — like Mauritius and Réunion — exploded, and that's where things get really interesting. Lucas: On Mauritius, the French and then the British had sugar plantations that needed a massive workforce. They first tried to use enslaved people from Madagascar and East Africa, and when the British abolished the slave trade in 1807, the planters there found ways to keep bringing in captives illegally. Luna: So the same kind of smuggling that happened in Brazil happened there too? Lucas: Exactly the same dynamics — just on the other side of the world. And the British navy was supposed to suppress it, but it was a low priority compared to the Atlantic. The Indian Ocean was vast and there were tons of hiding places along the coast. Lucas: But the biggest shift came in the 1830s and 40s with the rise of Zanzibar under Sultan Said bin Sultan. He moved his capital from Oman to Zanzibar and turned the island into the epicenter of the Indian Ocean slave trade. Luna: Zanzibar — that's where the cloves are from, right? Lucas: Yes! Clove plantations. Said bin Sultan made Zanzibar the world's leading clove producer, and the labor for those plantations was enslaved Africans. The demand was so great that the slave trade from the mainland boomed. Lucas: And it wasn't just cloves. The same caravans that brought slaves to the coast also brought ivory, and the two were often traded together. The great trader Tippu Tip — a name that sounds like a character from a novel — ran vast networks that stretched deep into the Congo basin. Luna: Tippu Tip — was he that powerful that he had his own army? Lucas: He did. He built a commercial empire based on ivory and slaves, and he controlled territory that would rival some European states. He even negotiated with European explorers like Henry Morton Stanley. He's a controversial figure — some see him as a brilliant entrepreneur, others as a brutal slaver who devastated the region. Lucas: And the scale of the trade in Zanzibar was staggering. It's estimated that in the mid-nineteenth century, anywhere from 20,000 to 50,000 slaves passed through the island's markets each year. Many were sent to the clove plantations, others shipped to Arabia, Persia, and India. Luna: That's a lot of people. And the conditions on those clove plantations — were they as harsh as the Caribbean sugar fields? Lucas: They were brutal in their own way. Long hours, poor food, and high mortality from disease. But there were also cultural differences in how slavery was practiced. In the Indian Ocean world, enslaved people were often employed in domestic households, and some even rose to positions of influence, like the Sidi communities in India who became soldiers and sailors. Lucas: But that doesn't soften the reality — the trade was based on violence and the systematic dehumanization of millions of people. And it was only the British naval patrols, starting in the 1860s, that began to seriously curb it. Luna: But by then, the Atlantic trade was already over. Why did the Indian Ocean trade last so much longer? Lucas: Because it was less visible to the Western public, and because the British had less political will to stop it. The Abolition Act of 1807 applied to British subjects, but the Sultan of Zanzibar wasn't British. So the British used treaties and diplomacy to chip away at it, but it was a slow process. Lucas: It wasn't until 1897 that the slave market in Zanzibar was officially closed — the last legally recognized slave market in the world. And even then, the practice continued illegally for years after. Luna: It's amazing how long this system persisted, and how it's so often left out of the story we tell about slavery. Lucas: Yeah, and that's partly because the Indian Ocean trade doesn't fit the narrative of the Atlantic plantation complex. It was smaller, more diffuse, and it involved non-European actors in a more direct way. But that doesn't make it less important — it's just a different thread in the same global web of exploitation. Lucas: And when you look at the numbers, the Indian Ocean trade may have involved as many as 12 million people over the centuries. That's comparable to the Atlantic, although the peak was earlier and the destinations were different. Luna: Wow. So when we say 'the slave trade,' we should be thinking about more than just the Atlantic. Lucas: Absolutely. The Atlantic is just one part of a much larger story. And I think that's one of the reasons we keep exploring these angles — there's always another layer to uncover. Lucas: You know, it's funny — we've made over two hundred episodes of this show, and every time we think we've covered it all, we find a new thread like this. And the only reason we can keep doing that is because a small group of listeners supports us directly. If you've been enjoying these deep dives, you can help keep the show going by buying us a coffee at buy me a coffee dot com slash fexingo. It's what keeps this ad-free. Luna: Yeah, it really does. We're grateful for every single person who chips in. Lucas: But let's get back to the story. Because there's one more piece of the Indian Ocean trade that connects it directly to the Atlantic — the island of Réunion. Lucas: Réunion was a French colony, and in the eighteenth and early nineteenth centuries, it was a major destination for enslaved people from East Africa and Madagascar. The French planters there produced coffee and sugar, and they relied on the Indian Ocean slave trade to keep their plantations running. Luna: So it's like a bridge between the two systems. Lucas: Exactly. And that bridge worked in both directions — some slaves from the Indian Ocean were also shipped across the Atlantic to the Americas, especially after the British and Americans abolished the Atlantic trade but before the Indian Ocean trade was suppressed. Lucas: So when we think about the Atlantic slave trade, we have to remember that it wasn't a closed system. It was part of a global economy of human trafficking that spanned oceans and continents. And the Indian Ocean was a key piece of that puzzle. Lucas: Today, the legacy of that trade is still visible — in the Swahili coast's architecture, in the languages, in the genetic diversity of places like Zanzibar and Mauritius. It's a reminder that the history we're telling is not just a series of events, but a living heritage. Luna: And it's a heritage that's often overlooked. Thanks for bringing it to light. Lucas: That's what we're here for. And if this episode sparked something, there's always more to explore — the story of the Indian Ocean is far from fully told.
