Islam spread to Africa in the early 7th century. Nowadays, almost one-third of the world's Muslim population lives on the continent. As of 2002, Muslims constituted 48% of the population of Africa.

Islam first spread to Africa during the Kingdom of Aksum, when Muslims crossed current Djibouti and Somalia to settle in Eritrea and Ethiopia in order to escape religious persecution. Other factors that motivated its spread was the expansion of the Islamic empire into Northern Africa and the Akan gold-salt trade in West Africa.
