Rhodesia made it illegal for archaeologists to tell the truth
A stone city proved Africans built a medieval kingdom — so a colonial government ordered scientists to say otherwise.
Great Zimbabwe is the largest stone structure built in precolonial sub-Saharan Africa: a walled city of granite blocks fitted without mortar, home at its height to thousands, built by ancestors of the Shona people between roughly the eleventh and fifteenth centuries.
When European settlers found it in the 1800s, they refused to believe local Africans had built it. Cecil Rhodes and the colonists who followed him credited it to Phoenicians, Arabs, almost anyone but the people living around it — because the alternative undercut the entire justification for colonizing the region in the first place.
The evidence said otherwise from the start. British archaeologist Gertrude Caton Thompson concluded in 1929, after digging her own test trenches, that the site was "in accordance with the claim of Bantu origin" and nothing else. It didn't matter. Rhodesia's government spent the 1960s and '70s pressuring museums, guidebooks, and textbooks to keep quiet about it. One government archaeologist, Peter Garlake, was told he could say "yellow people" built it — anyone, as long as it wasn't the truth. He eventually left the country rather than keep lying.
When the country won independence in 1980, it renamed itself after the ruins its former government had spent decades denying. The evidence had been sitting in the ground the whole time, indifferent to what anyone was permitted to say about it.
