Latest / Great Zimbabwe: The Lost African Kingdom of Stone — Fexingo History / Great Zimbabwe's Salt Miners: The Mambo's Underground Economy
Transcript
- Luna: So we've talked about gold, iron, copper, cattle, even grain — but I keep thinking about something we haven't touched on yet. Lucas: What's that? Luna: Salt. I mean, everybody needs it, and it's not like Great Zimbabwe was near the coast. Where did they get it? Lucas: That's a great question, and it actually opens up a whole underground economy — literally. Great Zimbabwe had its own salt mines, and they were a major source of the Mambo's wealth. The main source was along the Tugwi River, about a hundred kilometres south of the dzimbabwe. There, naturally saline springs and evaporite deposits produced what the vaShona called muraya — a brownish, mineral-rich salt that was highly prized. Lucas: Now, muraya wasn't just for seasoning food. It was used in preserving meat and fish, in tanning hides, and in various rituals. The Mambo controlled access to these deposits, and salt became a valuable trade commodity, just like gold or copper. In fact, salt was often used as currency in local markets, alongside cowrie shells and copper ingots. Luna: So the Mambo had a monopoly on salt? That must have given him enormous leverage. Lucas: Exactly. The salt mines were considered part of the Mambo's personal domain, managed by appointed officials. Miners — often prisoners of war or low-status individuals — worked under harsh conditions. They dug shallow pits and trenches, collecting the salt-encrusted soil, then leaching and evaporating it to produce the final product. It was dangerous work: cave-ins, snake bites, and respiratory problems were common. Lucas: But the salt trade also had a spiritual dimension. The vaShona believed that salt was a gift from Mwari, the supreme god, mediated by the mhondoro — the ancestral spirits. Before mining began, a nganga would perform rituals to ask for protection and a good yield. There were taboos too: women who were menstruating or pregnant were not allowed near the mines, and miners had to abstain from certain foods. Luna: Did the salt trade extend beyond the kingdom? I'm thinking of the Swahili Coast. Lucas: It did, but not as directly as gold. Salt is heavy and low-value per weight, so long-distance trade was limited. Most muraya was consumed locally or traded within a few hundred kilometres. However, salt was used to preserve fish and meat that were then traded to Sofala and Kilwa. So indirectly, salt supported the export economy. And within the kingdom, salt was a crucial part of lobola — bride wealth — paid in cattle, but also supplemented with salt and iron hoes. Luna: It's fascinating how something so basic can be so central to power. The Mambo really controlled everything from the ground up. Lucas: Absolutely. And that control extended to the distribution. The Mambo would gift salt to loyal chiefs and use it to reward warriors and officials. It was a way of binding the elite to him. At the same time, he could withhold salt as a form of punishment — a salt blockade against a rebellious province would cripple its ability to preserve food and conduct rituals. Lucas: You know, when I think about these episodes — the grain bins, the cattle herds, the iron hoes, the salt mines — it becomes clear that the Mambo's power wasn't just about grand stone walls. It was about controlling the everyday necessities of life. Luna: Which is what makes this show so compelling. You really get a sense of how the kingdom functioned on a practical level. Lucas: And that's what keeps us digging.

It's a simple way to help with research and production costs, and it really does make a difference. Luna: Yeah, every bit helps, and we appreciate everyone who's come along with us on this journey. Lucas: So back to the salt mines — there's one more fascinating detail. Archaeologists have found evidence that the salt mining sites were used for generations, with layers of salt and ash building up over centuries. Some of these sites are still visible today, with shallow pits and mounds of discarded soil. They're a testament to the ingenuity and organisation of the vaShona people. Luna: And I imagine the salt itself left traces — like, in the soil or in pottery? Lucas: Yes, exactly. Salt doesn't preserve well in the archaeological record, but indirect evidence like salt-impregnated potsherds and the remains of evaporation pans have been found. Also, the Tugwi River region has a distinctive geology — there are salt springs and salt pans that are still used today by local communities. So the continuity is remarkable. Lucas: The Mambo's salt monopoly wasn't just about economics. It was also about ritual purity. The vaShona believed that salt had cleansing properties, and it was used in purification ceremonies after contact with death or other polluting events. The Mambo, as the spiritual head of the kingdom, was the ultimate source of this purifying substance. Luna: So he was both the supplier and the high priest of salt. That's a powerful combination. Lucas: It really is. And it shows how tightly woven the material and spiritual worlds were in Great Zimbabwe. The Mambo didn't just rule — he mediated between the people, the ancestors, and the land itself. The salt mines were a physical manifestation of that connection. Luna: I'll never look at a salt shaker the same way again. Lucas: Ha! Neither will I. And that's the thing about history — it makes the ordinary extraordinary. Next time you sprinkle salt on your food, think of the miners along the Tugwi River, the nganga calling on the ancestors, and the Mambo sitting in his dzimbabwe, controlling it all.
