Ghana and the Gold-Salt Trade

Why this matters

Koumbi Saleh wasn't one city but two, and al-Bakri's account of its layout is one of the few details that survive about how the empire organized itself, not just what it traded. It sat in the western Sahel, nowhere near the coastline of the country that later borrowed its name.

Sitting on the route between Saharan salt and southern goldfields meant the empire never had to mine an ounce of gold to profit from every ounce passing through. Students who equate wealth with owning the resource have to rethink that here, because Ghana's wealth came from position, not production.

From one teacher to another

The correction I make on day one is that the country called Ghana today borrowed its name from an empire that sat somewhere else entirely and ended centuries earlier, so students spend the whole lesson learning about medieval Wagadu instead. The economics is the part that surprises them: Ghana never mined much of its own gold, it grew rich as the middleman sitting between Saharan salt in the north and goldfields in the south, taxing every donkey-load of salt that crossed its land at one dinar of gold coming in and two going out. They read al-Bakri's eleventh-century description of the king's gold-draped court, and I make them notice he never actually visited Ghana himself, he compiled it from merchants' reports, so it's a rich source but a secondhand one. It ends with them correcting two specific wrong claims about Ghana in writing, which is a better test of whether the middleman idea stuck than just answering multiple choice.
