- Lucas: So we've talked a lot about Mansa Musa's gold, his books, his mosques — but there's one commodity from his empire that I think we've completely overlooked, and it's something you and I use every single day. Luna: What is it? Lucas: Soap. Specifically, the shea butter soap that Mali produced and traded across the Sahara. And this wasn't just a minor cottage industry — I think it was one of the empire's most profitable exports after gold and salt. Al-Umari, writing in Cairo just a few years after Mansa Musa's hajj, notes that Mali's soap was considered the finest in all of North Africa. He calls it 'sabun al-Mali' — Mali soap — and says it was prized for its moisturizing qualities and its scent. Luna: Wait — people in Cairo and North Africa were buying soap from West Africa? Lucas: Absolutely. And not just a little — this was a major trade good. The shea tree grows wild across the savanna belt from Senegal to Sudan, and the nuts produce a fat that's unusually high in unsaponifiable compounds — that's what makes it so good for skin. Women in Mali had been processing shea butter for centuries, turning it into a rich, creamy soap by mixing it with plant ashes from certain trees. By the time of Mansa Musa, this was an organized industry with standardized production. The farba — the imperial governors — collected taxes on soap production, and the dyula merchants carried it northward in blocks wrapped in palm leaves. Luna: So the empire was taxing soap the way they taxed gold? Lucas: Exactly. And the scale is remarkable. Ibn Battuta, when he visited Mali in the 1350s — just after Mansa Musa's reign — describes markets in Timbuktu and Djenné where soap was sold alongside salt and copper. He specifically mentions that the women of Mali used this soap, and that it was considered a luxury item even within the empire. But the real money was in the trans-Saharan trade. A single caravan could carry hundreds of bars, each one wrapped individually, and the profit margin was enormous. In Cairo, a bar of Mali soap could fetch ten times what it cost in Niani or Timbuktu. Luna: That's a markup comparable to gold itself. What made it so valuable? Lucas: Partly the quality — shea soap is naturally moisturizing and it lathers beautifully, even in hard water. But also the cultural context. In the Islamic world, cleanliness is tied to ritual purity — you perform wudu before prayer, you bathe on Fridays. So a premium soap was both a practical good and a religious necessity. And Mali soap had a reputation. Al-Umari says that when Mansa Musa's caravan arrived in Cairo in 1324, the Egyptians were astonished by the cleanliness of his entourage — they used soap so frequently that the Mamluks took notice. Some historians think this was a kind of soft diplomacy: the Mali Empire projecting wealth and sophistication through personal hygiene. Luna: So Mansa Musa was literally washing his way into the hearts of Cairo. Lucas: I think there's truth to that. And it gets even more interesting when you look at the production side. The shea butter economy was largely controlled by women. Women harvested the nuts, processed the butter, and made the soap. It was a source of economic independence for them within the patriarchal structures of the empire. The farba would tax the finished product, but the women kept the profits from local sales. Ibn Battuta actually remarks on this — he says the women of Mali 'have more freedom than any women he had seen,' and part of that was their control over the soap and butter trade. Luna: That's a really different picture of the empire than just 'Mansa Musa the gold king.' Lucas: Exactly. And it shows how the empire's wealth wasn't just in precious metals — it was in everyday commodities that people needed. Soap, salt, cloth, copper. The gold got all the attention, but the shea soap trade was arguably more stable. Gold prices fluctuated based on European demand, but people always needed soap. Especially in the Sahel, where dry skin is a real problem. And the shea tree is incredibly resilient — it grows in poor soil, needs little water, and produces nuts for decades. It was a sustainable resource that kept generating wealth year after year. Luna: And the archaeological record backs this up? Lucas: It does. At sites like Djenné-Djenno, which predates the Mali Empire but continued into Mansa Musa's time, archaeologists have found soapstone molds and remnants of shea butter in pottery. There's also evidence of trade in shea products as far back as the first millennium CE. So when Mansa Musa's empire expanded, it didn't invent the soap trade — it systematized it. The imperial administration set standards for quality, collected taxes, and protected the trade routes. That's why Mali soap had such a good reputation: it was consistently high quality, because the farba would inspect shipments and reject substandard bars. Luna: Inspect soap shipments? That's amazing. So there were quality control inspectors for soap. Lucas: Yes, and they were part of a larger bureaucratic apparatus that managed trade in all commodities. The farba who oversaw the gold trade also oversaw soap, salt, and copper. And they kept detailed records. Al-Umari's source for his book Masalik al-Absar — which is one of our main sources on Mali — was actually a farba named Mansa Musa himself apparently appointed a special overseer for the soap trade, though the name doesn't survive. But we know from al-Umari that the soap trade was important enough to warrant its own officials. Luna: And this all ties back to Mansa Musa's hajj in a way. I mean, he was making a statement. Lucas: Absolutely. His hajj caravan wasn't just a display of gold — it was a display of everything the empire produced. The soap, the salt, the textiles, the spices. By the time he reached Cairo, people weren't just talking about his gold; they were talking about his soap, his clothes, his food. It was a total package of civilization. And the soap was a particularly clever choice because it's intimate — you use it on your body, you smell it. It created a sensory memory of Mali in the minds of Egyptians. So when they bought Mali soap in the markets later, they were buying a piece of that memory. Luna: So it was brand-building, essentially. Lucas: Exactly. And it worked. The reputation of Mali soap lasted for centuries. Even after the empire declined, shea butter from West Africa continued to be traded across the Sahara. And today, shea butter is a global commodity worth billions. But its origins as a luxury export really took off under Mansa Musa. He didn't just sit on his gold — he built an economy that produced goods people actually needed and wanted. And soap, humble as it sounds, was a key part of that. Luna: You know, this makes me think about how we choose what to cover on this show. We've done episodes on gold, on mosques, on libraries — all the flashy stuff. But the everyday things — soap, salt, cloth — they're just as revealing. Lucas: Absolutely. And honestly, that's part of why we can do deep dives like this. This show doesn't have to chase the obvious headlines because we're listener-supported. A small group of listeners chips in through buy me a coffee dot com slash fexingo, and that gives us the freedom to spend an episode on, say, the soap economy of Mali. No ads, no sponsors — just people who care about history. It's a pretty great arrangement. Luna: Yeah, and we get to follow the threads wherever they lead. Soap, salt, whatever. Lucas: Exactly. So, back to the soap. One thing I haven't mentioned is the spiritual dimension. Shea trees are considered sacred in many Mande cultures. They're called the 'tree of life' in some traditions. So turning the nuts into soap wasn't just a commercial act — it had ritual significance. Women would sing while they processed the butter, and the first batch of the season was often offered to the ancestors. Mansa Musa, as a devout Muslim, probably didn't emphasize the animist aspects, but the cultural practices persisted. Ibn Battuta actually describes a ceremony where the queen mother — or one of the royal women — distributed soap to the poor during Ramadan. It was a form of charity that reinforced social bonds. Luna: Soap as charity. That's a beautiful image. Lucas: It is. And it shows how a commodity can carry multiple meanings: economic, cultural, spiritual. Soap in Mali wasn't just about getting clean. It was about status, about piety, about community. And Mansa Musa understood that. He used soap the way he used gold — as a tool of diplomacy, as a symbol of his empire's sophistication. But unlike gold, which is inert, soap was something people used every day. It touched their lives directly. And that's why, I think, the soap trade outlasted the gold trade in some ways. After the empire fell, people still wanted Mali soap. The memory of it persisted. Luna: Is there any evidence of Mansa Musa personally using soap as a diplomatic gift? Lucas: There is. Al-Maqrizi, writing in 15th-century Cairo, records that Mansa Musa presented the Mamluk sultan al-Nasir Muhammad with gifts that included 'a hundred bars of scented soap from his country.' That's a direct mention. So yes, soap was part of the official gift exchange. And the Mamluks, who were very sophisticated about trade and luxury goods, recognized its value. They distributed it among their own court. So literally, the sultan of Egypt was washing with Mansa Musa's soap. That's soft power at its most intimate. Luna: That's incredible. And it makes me wonder what other everyday items from Mali were traded that we don't think about. Lucas: Oh, plenty. Leather goods, for one. The famous Moroccan leather was actually often made from hides brought from Mali. Indigo-dyed cloth, which was a major export to North Africa. And of course, spices — though those were more from the forest regions to the south. But soap really stands out because it's so well-documented. And because it tells us so much about the society that produced it. It wasn't just a product; it was a window into the lives of women, the organization of the economy, and the empire's connections to the wider world. And all of that is part of Mansa Musa's legacy, even if it's not as famous as his gold. Luna: I feel like I'll never look at a bar of soap the same way again. Lucas: I know what you mean. Every time I use shea butter soap now, I think of those women in Mali, the caravans crossing the Sahara, and Mansa Musa's hundred bars sitting in the sultan's palace. It's a reminder that history is in the details. And that the richest man who ever lived built his wealth not just on gold, but on things like soap — things that made life better for people. Luna: That's a good note to end on. Thanks for this deep dive, Lucas. Lucas: My pleasure. Next time, we'll look at something else from the everyday life of the empire — maybe the salt trade, which had its own fascinating story. Until then.
