Trans saharan trade began with transporting what item across the desert?

Trans-Saharan trade began primarily with the transportation of gold, which was highly sought after in North Africa and Europe. As trade routes developed, other goods such as salt, ivory, and slaves were also transported across the desert. The trade not only facilitated the exchange of commodities but also fostered cultural and economic connections between diverse civilizations. Over time, this network became crucial for the economies of various West African kingdoms.
