Analyzing the wealth and power of the Ghana, Mali, and Songhai empires.
What if you lived in a world where a block of salt was worth exactly the same as a block of pure gold? In the medieval empires of West Africa, this wasn't a fantasy—it was the foundation of the wealthiest civilizations on Earth.
The Kingdom of Ghana (c. 300–1200 CE) became the first great West African empire by acting as a 'middleman.' Located between the salt mines of the Sahara Desert and the gold fields of the Upper Niger River, Ghana controlled the Trans-Saharan trade routes. They didn't actually own the gold mines, but they taxed every load of goods that entered or left their borders. This 'Gold-Salt' trade was often conducted via silent barter, where traders left goods at a secret location to avoid revealing the locations of the mines. Because salt was essential for preserving food and replacing electrolytes lost in the heat, it was often traded at a ratio of with gold.
Imagine a merchant brings 50 slabs of salt into Ghana. 1. The King of Ghana charges a tax of gold coin for every slab entering. 2. The merchant sells the salt for gold in the south. 3. On the way back out, the King charges another gold coins for every slab of gold carried. Total tax collected by the King: gold coins without the King ever mining a single nugget.

Why was salt considered as valuable as gold in West Africa?
Answer
Salt was a biological necessity for survival in the heat and was used to preserve food in a time before refrigeration.
After Ghana declined, the Mali Empire (c. 1235–1670 CE) rose to even greater heights. Its most famous ruler, Mansa Musa, was a devout Muslim who took a famous hajj (pilgrimage) to Mecca in . He traveled with a caravan of 60,000 people and dozens of camels carrying pounds of gold each. As he passed through Cairo, Egypt, he gave away so much gold to the poor that the overall value of gold in the region dropped for over years. This journey put Mali on European maps, literally, as cartographers began depicting Musa holding a golden nugget.
Mansa Musa's generosity caused massive inflation. 1. He flooded the market with gold. 2. Because gold was suddenly common, its 'purchasing power' decreased. 3. If a loaf of bread cost gold grain before he arrived, it might cost gold grains after he left because the gold itself was worth less. This is a classic example of supply and demand.

How did Mansa Musa's pilgrimage change the world's view of West Africa?
Answer
It proved that West Africa was home to a sophisticated, incredibly wealthy, and powerful Islamic empire, leading to its inclusion on world maps.
Under the Songhai Empire, which succeeded Mali, the city of Timbuktu became the 'Oxford of the Medieval World.' It was situated at the point where the Niger River meets the Sahara. While it was a hub for gold and salt, its most precious commodity was knowledge. Timbuktu housed the University of Sankore and hundreds of libraries containing thousands of manuscripts. These books covered medicine, astronomy, law, and mathematics. In Timbuktu, it was often said that 'salt comes from the north, gold from the south, but the word of God and the treasures of wisdom come from Timbuktu.'
Consider the logistics of Timbuktu's intellectual wealth: 1. A scholar travels miles from Morocco to teach in Timbuktu. 2. A merchant trades camels worth of salt to buy a single rare hand-written manuscript. 3. The city becomes a 'brain gain' center, where the concentration of scholars creates new discoveries in and , which are then traded back to Europe and the Middle East.
Which empire was the first to control the Trans-Saharan trade routes?
What happened to the value of gold in Cairo after Mansa Musa's visit?
Timbuktu was primarily known for its military fortresses rather than its libraries.

Tomorrow, try to explain to a friend why a king would want to control a desert trade route even if he didn't own the mines himself.
