Six centuries of West African empires, told through the salt-and-gold caravan trade that paid for them.
Before steamships and silver mines, the world economy ran partly on the gold that came north out of the Bambuk and Bure goldfields. The story is not Mali or Songhai alone but a six-hundred-year conversation among them and the trans-Saharan trade that connected them to Cairo, Andalusia, and the Indian Ocean.

Where the trade hardened into permanence — a market town that grew into a university city.

Long before its name became, in distant corners of the world, a synonym for the impossibly remote, Timbuktu existed as a seasonal camp situated just north of the Niger River.

The rise and fall of the Songhai Empire hinged on the control of the great river highways and desert trade routes of the western Sahel.
1591. A Moroccan musketeer army crosses the Sahara and breaks Songhai at Tondibi. The era ends, but the goldfields and the routes remain.
The fate of the Songhai Empire, the dominant force in Western Africa for over a century, was decided not by numbers, but by the terrifying crack of gunpowder.
