While most Arabs in Sudan are Sudanese Arabs, with most of Sudan's Arab population speaking modern Sudanese Arabic, with western Sudanese province tribes bordering Chad like the Baggara and Darfurians generally speaking Chadian Arabic. Sudanese Arabs have large variations in culture and genealogy because of their descent from a combination of various population groups. Most Sudanese Arabs are descended from culturally and linguistically Arabized or assimilated indigenous Nubian, and Cushitic peoples of Sudan (predominantly from the Beja people and Nubian people who have a historical Pre-Arab connection to Egypt) with the addition of varying cases of distant admixture with Arabs of the Arabia Peninsula that migrated to The Sudans in the 12th century AD during the introduction of Islam in the region. Other Arab population in Sudan that are not ethnically Sudanese Arab, i.e. those that are recent arrivals to the region exist, and most of them such as the Awadia and Fadnia tribes, the Bani Hassan, Al-Ashraf and Rashaida tribes generally speak Hejazi Arabic instead of the more widespread Sudanese Arabic.
