At Taghaza they built houses from salt. Camels carried the bars south for gold

In 1352 the Moroccan traveller Ibn Battuta reached a place in the Sahara that had no trees and almost no comfort. He had ridden for twenty-five days from Sijilmasa, in what is now Morocco. What he found was sand, flies, brackish water, and a commodity so valuable that, he wrote, qintars of gold dust were traded there despite the squalor.

The place was Taghaza, in the far north of present-day Mali. Its wealth was not gold. Its wealth was salt.

A town cut from the thing it sold

Ibn Battuta described the houses and the mosque as built from blocks of salt, roofed with camel skins. Under the sand the miners dug thick slabs of rock salt, stacked one on top of another as if someone had squared them with a tool and laid them underground. Two slabs made a camel load. The people who dug them lived on dates and millet brought in from far away. Food had to travel to Taghaza. Salt travelled out.

That is a hard business model. You are mining in one of the driest, hottest corners of the earth, and every meal depends on a caravan that may or may not arrive. Leo Africanus, who spent three days there around 1510, wrote that starvation was a real risk because the mines sat about twenty days from a reliable source of food. The work continued anyway, because West Africa needed salt and would pay for it in gold.

Value rose with the journey

Salt from Taghaza did not stay in the desert. It was carried south to Oualata and, later, to Timbuktu, then deeper into the Mali Empire and beyond. Ibn Battuta recorded that a load worth eight to ten mithqals at Oualata could sell for twenty to thirty, and sometimes forty, in the town of Mali. The product was the same slab. The price changed because of distance, risk and time.

In parts of the region, he noted, people cut salt into pieces and used it as a medium of exchange, the way others used gold or silver. Salt was not only a seasoning. It was a store of value that survived the desert better than many softer goods.

Taghaza appeared on Europe's Catalan Atlas of 1375, marked on the caravan route between Sijilmasa and Timbuktu. By the fifteenth century Alvise Cadamosto was told that Taghaza salt moved through Timbuktu and Mali and then "a great distance" further to be bartered for gold. For centuries the salt pans of the western Sahara and the goldfields of West Africa pulled each other into one system.

When the route and the power shifted

In the sixteenth century Taghaza became a prize. The Songhai Empire controlled it. Moroccan Saadian sultans wanted the tax and the salt. They occupied the mines more than once. Production shifted to nearby pans, including what became Taoudenni. After the Moroccan victory at Tondibi in 1591 and the collapse of Songhai power, Taghaza was abandoned as the main centre. Taoudenni, closer to Timbuktu, took its place.

When the French explorer René Caillié passed in 1828, the salt-brick ruins were still visible. The system had moved. The old town had not.

What Taghaza teaches a business today

Taghaza is a story about a commodity, but the useful lesson is about logistics, dependency and the record of what moves.

The hard part is often not the product. It is keeping the product moving. Salt in the pan was abundant. Salt two months south, still intact, in the right hands, with a price both sides accepted, was the business. In a factory the same is true. Raw material on the bay is not finished goods. Finished goods without a clear path from intake lot to dispatch are inventory you cannot defend.

Distance multiplies both value and risk. Taghaza salt rose in price as it travelled because each stage added cost and uncertainty. Your plant has its own "desert": every hand-off where the lot ID is dropped, every stage with no named check, every night the cloud link fails and nobody buffers the reading. Map those stages. Price is not the only thing that compounds across them. Error does too.

Do not build your town out of the only thing you sell without a backup. Taghaza's houses were salt. Its food was imported. When politics and routes shifted, the mine that could not feed itself lost. Diversify what you depend on: suppliers, power, connectivity, the people who know the process. And keep a record that survives when one of them fails.

When the route moves, move the work — or lose it. Taghaza did not vanish because salt stopped mattering. It vanished because safer or nearer pans and new political control redirected the caravans. Watch where your customers, carriers and regulators are actually going. Protect the capability that can relocate with you: the know-how, the standards and the data.

This is the work I care about at Tamalaki when we build FactoraERP and FactoraIoT. A manufacturing system is a modern caravan ledger. Every lot should be loadable, checkable and followable from the gate to the truck. Sensors should keep conditions with the batch when the line cannot wait for a spreadsheet. The desert is different now. The need for a trustworthy record of what moved is not.

So here is my question for you this week: if one of your key routes closed tomorrow — a supplier, a line, a market — could you still name every lot already in motion, and would your record travel with them?
