The trans-Saharan trade revolutionized Africa from the 8th to 16th centuries. This network of routes across the Sahara Desert connected North Africa with West African kingdoms, facilitating the exchange of goods, ideas, and cultures. Gold, salt, and slaves were key commodities. Islam spread rapidly through these trade routes, transforming West African societies. The wealth generated by trade led to the rise of powerful kingdoms like Ghana, Mali, and Songhai. This period saw significant cultural exchange, urban development, and the emergence of Islamic centers of learning.
