How did Arab migrations influence North Africa and areas south of the Sahara?

Arab migrations into North Africa, beginning in the 7th century, profoundly transformed the region’s cultural, linguistic, and religious landscape through the spread of Islam and the Arabic language.12

Impact on North Africa

The arrival of Arab conquerors led to the rapid conversion of the indigenous Imazighen (Berbers), who were subsequently enlisted in further expansions, such as the incorporation of Andalusia into the Islamicate state. Over time, particularly in regions like Tunisia, intermarriage and cultural contact resulted in the assimilation of many Berber populations into Arab identity. This admixture created the distinctive Maghrebian culture, where Arabic became the dominant language.312

Influence South of the Sahara

Arab influence extended into the Sahara and western Africa through trade and the migration of Arabized tribes, such as the Kunta. These groups dominated trans-Saharan trade routes and became central figures in the spread of Sufi brotherhoods, or tariqas, which promoted a more organized and devout form of Islam. By the 18th century, these religious orders provided a framework for social and political change, often justifying the jihad against rulers deemed non-Muslim, a doctrine that significantly influenced pastoralist groups like the Fulani.4
