Across the Sahara: Mali and the Trans-Saharan World

The Sahara was not a wall but a sea of sand crossed by camel caravans that linked West Africa to North Africa and the Mediterranean. Gold from West African fields was traded north, while salt, cloth and books travelled south, making empires such as Ghana, Mali and Songhai wealthy. Trade also carried Islam, which spread first among merchants and rulers, so that cities like Timbuktu became centres of scholarship with large manuscript libraries.

The most famous symbol of this connection is Mansa Musa of Mali, whose pilgrimage to Mecca in 1324 passed through Cairo with so much gold that observers said its value fell there for years. Europeans noticed: the Catalan Atlas of 1375 shows him holding a gold nugget. These networks show that West Africa was central to medieval global exchange, which challenges older stories that treated Africa as isolated.
