The trans-Saharan trade was an important gateway for the spread of Islam in Africa. The legacy of the medieval empires and nineteenth century reform movements continues to have relevance in present day Senegal, Gambia, Mali, Nigeria, Burkina Faso, Nigeria, as well as many neighboring communities. The main items traded were gold and salt. The gold mines of West Africa provided great wealth to West African Empires such as Ghana and Mali. Other items that were commonly traded included ivory, kola nuts, cloth, slaves, metal goods, and beads.
