What where the empires of west Africa best known outside of the region?

The empires of West Africa, particularly the Ghana, Mali, and Songhai empires, were best known outside the region for their immense wealth, particularly in gold, and their thriving trade networks. These empires facilitated the exchange of goods, culture, and ideas across the Sahara Desert, connecting sub-Saharan Africa with North Africa and beyond. Additionally, the Mali Empire gained fame for its legendary ruler Mansa Musa, whose pilgrimage to Mecca in 1324 showcased the region's wealth and sophistication. Their contributions to scholarship, particularly in cities like Timbuktu, further highlighted West Africa's importance in the medieval world.
