Most genetic studies have determined that Maghrebi Arabs and Maghrebi Berbers are genetically nearly identical, thus making Arabization more of a cultural phenomenon rather than a genetic one. The Arab-Berber identity came into being as a direct result of the Arab conquest of North Africa, and the intermarriage between the Arabian and Persian people who immigrated to those regions and local mainly Roman Africans and other Berber people; in addition, Banu Hilal and Sulaym Arab tribes originating in the Arabian Peninsula invaded the region and intermarried with the local rural mainly Berber populations, and were a major factor in the linguistic, cultural and ethnic Arabization of the Maghreb.
