First, only Sudan and Somaliland became Arabized and Islamized. West Africa felt the presence of Islam through north African traders who travelled south of the Sahara. By the 14th century, there were already Muslim princedoms in such areas as Mali and Timbuktu in western Africa. Harare in eastern Africa became centers of Islamic learning. Gradually, Islam moved inland and south. The expansion of the Islamic Civilization into Africa did not stop during the colonial period, and continues today. Most Africans are now Muslims.
