Islam is one of the three major religions in the world. How did Islam spread in Africa?

There are two main ways to spread traditional Islam in Africa: one is to conquer and control African tribes and societies by means of war, and finally force local people to convert to Islam. This method was particularly common at the beginning of the introduction of Islam into Africa. Even at the beginning of the 20th century, the phenomenon of promoting the spread of Islam through jihad can still be seen in Africa. The other is peaceful infiltration. Mainly rely on the religious influence brought by Arab businessmen in the trade process for a long time, as well as lobbying from religious professionals in the Middle East and the follow-up. The practical benefits brought by Arab merchants induced the rulers at that time to take the initiative to accept Islam, thus achieving top-down conversion in some areas. There are new subjects and channels for the spread of Islam in contemporary Africa, among which new media such as new immigrants, overseas students and new online media have played a very important role.
