6.1 History and Expansion of Islam in Africa
Considering the emergence and long development of Islam, now in its fifteenth century, it is often forgotten that Islam crossed over to Ethiopia in the very first decade of its existence, during the life of Prophet Muhammad (peace be upon Him), before the Hijra to Medina in AD 622 and indeed before the Message (al-risala) was complete (it was completed on the death of the Prophet of Allah). That first Hijra to Ethiopia was of great significance to the new faith and to the beleaguered community of the early Meccan Muslims. Both were warmly received and protected according to Muslim traditions. Such was to be, in a majority of cases, the character of future relations between Islam and Muslims and the rest of Africa when these had occasion to be there.
Horn of Africa
Some of the early Muslims migrated to Ethiopia were granted protection and are said to have then settled in several parts of the Horn region to promote the religion. The victory of the Muslims over Quraysh in the 7th century had a significant impact on local merchants and sailors, as their trading partners in Arabia had then all adopted Islam, and the major trading routes in the Mediterranean and the Red Sea came under the sway of the Muslim Caliphs. Through commerce, Islam spread amongst the Somali population in the coastal cities. Instability in the Arabian Peninsula saw further migrations of early Muslim families to the Somali seaboard. These clans came to serve as catalysts, forwarding the faith to large parts of the Horn region.
The Horn of Africa is a peninsula in East Africa that juts hundreds of kilometers into the Arabian Sea and lies along the southern side of the Gulf of Aden. It is the easternmost projection of the African continent. Referred to in ancient and medieval times as Bilad al Barbar ("Land of the Berbers") the Horn of Africa denotes the region containing the countries of Eritrea, Djibouti, Ethiopia and Somalia.
6.1 History and Expansion of Islam in Africa
The spread of Islam into HOA
On the east coast of Africa, where Arab mariners had for many years journeyed to trade, mainly in slaves, Arabs founded permanent colonies on the offshore islands, especially on Zanzibar, in the 9th and 10th century. From there Arab trade routes into the interior of Africa helped the slow acceptance of Islam.
In the 20th century, Islam grew in Africa both by birth and by conversion. The number of Muslims in Africa grew from 34.5 million in 1900 to 315 million in 2000, going from roughly 20% to 40% of the total population of Africa.
