When Mansa Musa took power, the Mali Empire stretched from the Atlantic Ocean to Lake Chad, comprising parts of modern Niger, Nigeria, Mali, Burkina Faso, Gambia, Senegal, Guinea-Bissau, Guinea and Mauritania. By the end of Mansa Musa’s reign, it would include Timbuktu, Gao, and Ghana. The Sahara “Sahel” formed the northern border, and the tropical equatorial forests ran along the southern edge.
how important a commodity salt was in antiquity. Salt was often used as a payment for work or goods received, in part because salt was scarce and not generally available. It is important for health and is the main source of sodium and chloride ions for people, essential for nerves and muscle function. Salt helps transport body fluids, assists in maintaining a healthy blood pressure, and acts as a disinfectant that can be used for cleaning all kinds of wounds. Perhaps most importantly for the ancients, salt was a preservative, particularly in hot climates. Preserved food could be conveyed over greater distances, food could be stored, and people soon discovered that it enhanced the taste of almost everything they ate. West Africa had an abundance of gold but no salt, while North Africa had many sources of salt and no gold, so the exchange of these two vital commodities formed the basis of the extraordinarily successful and rich trading caravans that crossed the Sahara.
Gold and salt were the main commodities, but there were many other goods. Caravans traveling north carried gold, ivory, ostrich feathers, ambergris, kola nuts, hides, and slaves, while caravans heading south brought salt, textiles, copper, silver, ironware, spices, books, paper, wheat and fried fruit. Silent trade is described as the way gold and salt were typically traded. The traders of the commodities often did not have a language in common, which made things difficult since there was a need to keep the source of the product as much a secret as possible. Herodotus, the ancient Greek historian, wrote about the traditional way of solving this problem in West Africa when he described how the seafaring Carthaginians traded with a nation “beyond the Pillars of Hercules.”
A good introduction to Mansa Musa. His empire and Timbuktu as well as his hajj to Mecca.
