Where did trans-saharan trade take place

Trans-Saharan trade took place across the Sahara Desert, linking North Africa with Sub-Saharan Africa. Major trade routes crossed the desert from cities such as Cairo, Tunis, and Tripoli in the north to cities like Timbuktu, Gao, and Djenne in West Africa. These trade routes facilitated the exchange of goods, ideas, and cultures between the African regions.
