The desert-crossing system that connected West Africa to North Africa, the Mediterranean, and the wider Islamic world — carrying gold, salt, books, scholars, horses, textiles, ideas, and enslaved people across the Sahara for more than a thousand years.
The largest hot desert on Earth was never an empty wall between two worlds. For more than a thousand years it was a crossing, threaded by caravans that carried gold and enslaved people north, and salt, horses, books, scholars, and Islam south. The same roads that made West Africa richer and better connected also made its people more extractable, and both rode the same camels.
