As far as Africa is concerned, Islam entered into East Africa at the very beginning of the Islamic period but remained confined to the coast for some time, only the Sudan and Somaliland becoming gradually both Arabized and Islamized.
West Africa felt the presence of Islam through North African traders who travelled with their camel caravans south of the Sahara. By the 14th century there were already Muslim sultanates in such areas as Mali, and Timbuctu in West Africa and Harar in East Africa had become seats of Islamic leaming.
Gradually Islam penetrated both inland and southward. There also appeared major charismatic figures who inspired intense resistance against European domination.
The process of the Islamization of Africa did not cease during the colonial period and continues even today with the result that most Africans are now Muslims carrying on a tradition which has had practically as long a history in certain areas of sub-Saharan Africa as Islam itself.
In Africa also major countries with large or majority Muslim populations such as Nigeria, Senegal and Tanzania began to gain their independence in the 1950's and 1960's with the result that by the end of the decade of the 60's most parts of the Islamic world were formed into independent national states. There were, however, exceptions. The Muslim states in the Soviet Union failed to gain their autonomy or independence. The same holds true for Sinkiang (called Eastem Turkestan by Muslim geographers) while in Eritrea and the southern Philippines Muslim independence movements still continue.
