How did Islamic religion and culture come to West Africa ?

The first West Africans to be converted were the inhabitants of the Sahara, the Berbers, and it is generally agreed that by the second half of the tenth century, the Sahara had become Dar al-Islam that is the country of Islam.

After the Berbers’ Islamization, the religion spread into the Western Sudan from the closing decades of the tenth century. First, Islam spread into the regions West of the Niger Bend (Senegambia, Mali), then into Chad region and finally into Hausa land.

Explanation:

Africa was the first continent, that Islam spread into out of Arabia in the early seventh century. Almost one-third of the world’s Muslim population resides today in the continent. It was estimated in 2002 that Muslims constitute 45% of the population of Africa. Islam has a large presence in North Africa, West Africa, the horn of Africa, the Southeast and among the minority but significant immigrant population in South Africa.
