1. Salt: This was a vital commodity in West Africa, where it was scarce. Berbers brought salt from the Sahara Desert to trade for goods like gold, ivory, and slaves.
2. Manufactured goods: This included items like textiles, metal goods, and ceramics from North Africa and the Mediterranean region. These goods were in high demand in West Africa, providing a market for Berber traders.
It's important to note that the trans-Saharan trade was a complex and multifaceted system, and Berber traders brought other goods as well, depending on the specific routes and times.
