- Lucas: So we've talked about the stone walls, the gold, the cattle — but there's one material that underpinned all of it, and we haven't given it its due. Iron. Luna: Iron? I thought gold was the big deal. Lucas: Gold was the export, sure, but iron was domestic. It was the everyday metal that made everything else possible. Hoes for farming, axes for clearing land, spears for hunting and war, and tools for carving that soapstone you loved in episode 198. Without iron, Great Zimbabwe couldn't have fed itself, let alone built those massive walls. Luna: So iron was the workhorse. But they were importing it or making it locally? Lucas: They were making it. Right there on the plateau. Archaeologists have found evidence of iron smelting in the region dating back centuries before Great Zimbabwe even rose. The vaShona, the ancestors of the people who built the city, were skilled ironworkers. They used small clay furnaces, about a metre tall, fired with charcoal, and they'd get temperatures high enough to produce a bloom — a lump of spongy iron that they'd then hammer out. Luna: So they were basically self-reliant. No need to import iron from the coast. Lucas: Exactly. And that self-sufficiency was a cornerstone of their power. The Mambo, the king, controlled the best iron ore sources. They were often located in specific hills, and access was restricted. The smiths themselves held a special status — they were more than just craftsmen; they were ritual specialists, often associated with the mhondoro, the ancestral spirits. The process of smelting was wrapped in taboos and ceremonies. Women were often excluded from the furnaces, and the smith would offer prayers to Mwari, the high god, before lighting the fire. Luna: So the blacksmith was a kind of priest too. Lucas: In many ways, yes. The skill was passed down within families, and the smith's role was both practical and mystical. He could make a hoe that would break if not properly blessed, or forge a spear that carried the spirit of the ancestors. That gave the Mambo a lot of leverage. By controlling the smiths, he controlled both the tools of production and the spiritual forces that made them work. Lucas: And the iron itself — the raw material — often came from surface deposits or shallow mines. There were known iron ore outcrops in the hills around Great Zimbabwe, and the vavaki, the builders, used iron tools to quarry the granite blocks for the walls. So the iron industry was woven into the daily life of the city. Luna: I remember you mentioning that the Hill Complex had some kind of workshop areas. Was that where the smiths worked? Lucas: There are traces of metallurgical activity there. Slag heaps, pieces of tuyeres — those are the clay pipes that blow air into the furnace. Some of that might have been for ritual purposes, because the Hill Complex was a sacred space. But there were probably smithies in the valley too, closer to the Great Enclosure, where the everyday work happened. Lucas: What's interesting is that the iron industry wasn't just about local consumption. There's evidence that iron tools, especially hoes, were traded along the same routes that carried gold and ivory to the Swahili coast. Hoes were a form of currency in some parts of Africa, a store of value like cattle. So iron production wasn't just a support system — it was a source of wealth in its own right. Luna: Wait, so iron was actually an export too? Not just gold and ivory? Lucas: We don't have as much direct evidence as we do for gold, but there are accounts from the coast mentioning that iron was traded inland. And at sites like Mapungubwe and Khami, which were connected to Great Zimbabwe, they found iron objects that could have come from the same production centers. So it's likely that iron was part of the broader exchange network, even if it wasn't as glamorous as gold. Lucas: Now, about those Zimbabwe birds — the soapstone carvings that have become symbol of the nation. We talked about them before, but there's a curious detail. Some of them had iron rods embedded in their bases. They were probably mounted on poles, and the iron might have been symbolic — a connection to the earth, or to the power of the smith. Some scholars think the birds represented the link between the spiritual and the earthly, and iron, being a transformative material, would have been a fitting element. Luna: So the birds weren't just soapstone. They had a core of iron. That kind of changes the picture. Lucas: It does. And it shows that iron wasn't just utilitarian — it had deep symbolic meaning. The smith who forged those rods would have been a person of great prestige. Lucas: The decline of Great Zimbabwe around the 15th century is often linked to overgrazing and deforestation. But iron smelting was a major consumer of wood for charcoal. Some researchers have suggested that the sheer scale of iron production over several centuries might have contributed to the environmental pressures that eventually weakened the city. It's a reminder that even the most impressive civilizations can be undone by their own resource use. Luna: So in a way, iron helped build the city, but it also helped bring it down. Lucas: That's a fair way to put it. But the knowledge didn't disappear. The techniques were carried to later states like the Mutapa and Rozvi empires. Even today, some blacksmiths in the region continue to use traditional methods, though they're rare. The legacy of that iron age lives on in the names of places and in the oral traditions that speak of the great smiths of old. Luna: You know, it's funny — we've spent so many episodes on gold and stone, and iron was the real foundation. It's like the unsung hero. Lucas: It really is. And that's a theme that runs through so many histories — the materials we overlook are often the ones that matter most. Speaking of which — we're digging into these stories because we love them, and we keep the show free of ads because we think that's a better way to share history. If you're finding these conversations valuable, and you want to support that choice, you can find us at buy me a coffee dot com slash fexingo. Every little bit helps keep the fires burning. Luna: Yeah, it's a nice way to say thanks without sitting through commercials. Lucas: Absolutely. And on that note, we should get back to the iron. Because there's one more aspect that I think is really fascinating — the way iron was used in rituals of kingship. Luna: Oh, tell me more. Lucas: There are accounts from the 19th century, collected from the descendants of the Great Zimbabwe builders, that the Mambo's power was believed to be tied to a sacred iron staff. The staff was said to be made from iron that had been smelted in a special ceremony, and it was kept in the royal enclosure. When the king died, the staff was passed to his successor in a ritual that confirmed their right to rule. The iron wasn't just a symbol of power — it was a conduit for it. Luna: So the staff was like the crown jewels, but made of iron. Lucas: Exactly. And it's interesting that the mhondoro, the spirit mediums, also used iron objects in their rituals — iron bells, iron wands. The association between iron and spiritual authority runs deep. So when we think about Great Zimbabwe, we have to imagine not just a city of stone, but a city of fire — furnaces glowing, hammers ringing, and the smell of smoke and iron in the air. Luna: That's a vivid image. I'll never think of iron the same way again. Lucas: And that's the thing — history is full of these overlooked materials that shaped everything. Iron is just one example. Next time you pick up a steel tool, think about the tradition that started thousands of years ago in Africa. It's a thread that connects us all.
