- Lucas: You know, when people think of Mansa Musa's wealth, they immediately jump to gold. And yeah, the gold was extraordinary — the sheer scale of it, the way he distributed it in Cairo, the legends. But there's another metal that was arguably just as crucial to the Mali Empire's economy, and it doesn't get anywhere near the attention. Luna: Silver? Or something else? Lucas: Copper. And that's not a second-place metal here. In much of West Africa, especially before the arrival of European trade goods, copper was sometimes more valuable than gold. It was used for jewelry, for ritual objects, for currency — and Mali controlled some of the richest copper sources in the Sahel. Luna: Wait, more valuable than gold? How does that work? Lucas: It comes down to supply and demand. Gold was actually relatively abundant in the Bambuk and Wangara regions — the Malian heartland. But copper had to come from much farther away. The main source was Takedda, a town in what's now northern Niger, about a thousand kilometers northeast of Niani. That's a brutal journey across the Sahara. So copper was scarce, it was beautiful, and it carried prestige. Lucas: Ibn Battuta visited Takedda in the 1350s, about two decades after Mansa Musa's reign. He described it as a bustling mining town where women wore copper ornaments that would have been unimaginable in other parts of the world. He even mentions that the copper was traded as far as the Hausa states and the forest regions to the south. Luna: So the copper came from the Sahara, not from within Mali itself? Lucas: Exactly. And that's the genius of the Mali Empire's economic strategy. They didn't just sit on their own gold mines. They controlled the trade routes that connected the goldfields of the south to the salt mines of Taghaza and the copper mines of Takedda. The farba, the imperial governors, regulated this trade and collected taxes. It was a three-legged stool: gold, salt, and copper. Lucas: The copper from Takedda was actually a very pure form — almost 99 percent. It was cast into ingots, rods, and even small bars that functioned as currency. In some parts of West Africa, these copper bars were accepted for transactions long after the Mali Empire declined. They had real, lasting value. Luna: Were there any other copper sources that Mali used? Lucas: There were smaller mines in the Air massif and in the region of modern-day Burkina Faso, but Takedda was the big one. The Moroccan traveler Al-Umari, who wrote about Mali just a few years after Mansa Musa's reign, mentions that copper was imported from the Maghreb as well — especially from the town of Tamentit, in what's now Algeria. So Mali was at the center of a vast network. Lucas: And the copper wasn't just for show. It had practical uses. Copper tools, especially for woodworking and leatherworking, were highly prized. And because copper doesn't rust like iron, it was used for things that needed to last — like vessels for water, or ceremonial regalia. The Malian elite, including Mansa Musa himself, would have worn copper ornaments as symbols of status. Luna: I've seen replicas of those heavy copper bracelets and anklets — they look incredibly intricate. Lucas: Absolutely. And the craft was highly specialized. The jeliw — the griots — often sang the praises of the blacksmiths and copper workers, who were considered almost magical for their ability to transform raw metal into art. The Kouroukan Fouga, the constitution of the Mali Empire, even had specific provisions protecting the rights of these artisans. Luna: So the copper trade was a huge deal. But did it decline after Mansa Musa's time? Lucas: It did, but slowly. Part of the reason was that the mines at Takedda were incredibly remote. The journey from Niani to Takedda took about two months by camel caravan, and the route was vulnerable to raids by Tuareg and other nomadic groups. After the Mali Empire fragmented in the 15th century, control of the copper trade shifted to newer powers like the Songhai Empire and the Hausa states. Lucas: There's also an environmental angle. Mining copper in the Sahara required massive amounts of wood for smelting — wood was used both as fuel and as a source of charcoal. Over centuries, this deforested the areas around the mines. Ibn Battuta noted that Takedda was surrounded by 'numerous wells and trees,' but by the 16th century, the landscape had changed dramatically. Luna: So they basically used up the local forests. That's a sobering thought. Lucas: It is. And it's a reminder that even the wealthiest empires face limits — of resources, of geography, of time. But for a few centuries, the copper from Takedda helped make Mali the richest empire in the medieval world. And it's a story that deserves to be told. Luna: Speaking of stories worth telling — if anyone's enjoyed this one, we do have a way for listeners to support the show. Lucas: Yeah. We keep this show ad-free and independent, and it's only possible because of listeners who chip in. If today's episode felt worth a coffee to you, that's the link — buy me a coffee dot com slash fexingo. Luna: Every bit helps keep these conversations going. Lucas: Exactly. So back to the copper — there's one more layer I find fascinating. The copper from Mali wasn't just used in West Africa. It traveled across the Sahara to North Africa, and from there, some of it may have reached Europe. Spanish copper mines in the 14th century were in decline, and the Italian city-states were importing metal from the Maghreb. Some of that almost certainly started as Malian copper. Luna: So Mansa Musa's copper might have ended up as church bells in Florence? Lucas: It's possible. The trade networks of the medieval world were more connected than we often assume. And copper is a metal that doesn't lie — it can be traced chemically. There's been some work on lead isotope analysis of copper artifacts from Italy and North Africa, and it shows that some of them originated in the Sahara. Not definitively Takedda, but the signature matches. Luna: That's amazing. So we might be able to prove that Mansa Musa's copper reached Europe. Lucas: We might. And that's the kind of thing that keeps historians excited. Because it's not just about the gold and the legends — it's about the everyday materials that built empires and connected continents. Copper was one of those materials, and it deserves its place in the story. Luna: I'll never look at a copper coin the same way again. Lucas: Good. That means we did our job. So next time you're in a museum and you see a copper bracelet from West Africa, you'll know it's not just an ornament — it's a piece of a vast, complex economy that stretched from the Niger River to the Mediterranean. Luna: And a reminder that Mansa Musa's wealth was built on more than just gold. Lucas: Exactly. That's the takeaway. Thanks for listening.
