In 1324, a king from West Africa set out to cross the Sahara on a pilgrimage to Mecca. Travelers said he brought thousands of people and camels carrying gold. When he stopped in Cairo, he gave away so much gold that its price fell there for years. He was Mansa Musa, ruler of Mali, and people still call him one of the richest people who ever lived.
Key idea
Why trade gold for salt? In the south, near the gold fields, it was hot and people needed salt to stay healthy and to keep food from spoiling, but there was little salt there. In the Sahara there were great salt mines, but no gold. Camel caravans carried slabs of salt south and gold north.
Mali's city of Timbuktu became a center of learning, with scholars, mosques and libraries of handwritten books. Families there still keep thousands of old manuscripts on mathematics, astronomy, medicine and law.
Worked example: Trade
- The Sahara had salt mines but no gold.
- The lands to the south had gold but little salt.
Answer: Salt, to trade for gold.
Common mistake
Try it at home
- Play a trading game: give one person "gold" (yellow paper squares) and another "salt" (white squares). Each needs some of the other's goods. Agree on a fair trade.
- Find the Sahara, Mali and Ethiopia on a map or globe.
