A network of zawiyas traditionally helped proliferate basic literacy and knowledge of Islam in rural regions.

By the 2nd century common era, the area had become a center of Latin-speaking Christianity.

Both Roman settlers and Romanized populations converted to Christianity.

According to Institut national de la statistique et des études économiques (the French National Institute for Statistics and Economic Studies), 16% of newborns in France between 20 have at least one Maghrebi grandparent born in the Greater Maghreb.

In 2005, the percentage of young people under 18 of Maghrebi origin (at least one immigrant parent) were about 7% in Metropolitan France, 12% in Île-de-France, 13% in Lyon, 21% in Perpignan, 22% in the department of Seine-Saint-Denis, 37% in 18th arrondissement of Paris and 40% in several arrondissements of Marseille.

Maghrebis or Maghrebians are the native inhabitants of the Maghreb in Northwest Africa.

Maghrebis were known in medieval times as Roman Africans or Moors.

However, in September 2010, a thorough study about Berber mt DNA by Frigi et al.

concluded that most of L haplogroups were much older and introduced by an ancient African gene flow around 20,000 years ago.

The genetic proximity observed between the North-Africans and Southern Europeans is due to the fact that both these groups shared a common ancestor either in the Upper Paleolithic, in the Neolithic or alternatively during history with the invasion and the occupation during nearly seven centuries of the Iberian Peninsula by Moorish troops.
