Berber languages suggests that the C-Group population — which, along with the Kerma culture, inhabited the Nile valley immediately before the arrival of the first Nubian speakers — spoke Afro-Asiatic languages. Roger Blench (2018) suggests that Proto-Berber speakers had spread from the Nile River valley to North Africa 4,000-5,000 years ago due to the spread of pastoralism, and experienced intense language leveling about 2,000 years ago as the Roman Empire was expanding in North Africa. Hence, although Berber had split off from Afroasiatic several thousand years ago, Proto-Berber itself can only be reconstructed to a period as late as 200 A.D. Blench
Berber flag Berber flag The Berber flag () is a flag that has been adopted for the Berbers. It is currently used by Berber activists in 10 African countries. The flag was inaugurated in Ouadhia, a town of Kabylia situated in Tizi Ouzou, a wilaya of Algeria, by an elder Algerian Kabylian "veteran" named Mohand Arav Bessaoud. He was considered a spiritual father of Berberism and was also a writer and an activist of the Algerian Revolution. In the 1970s the Berber Academy ("Agraw Imazighen") proposed the first Berber flag. In 1998 the World Amazigh Congress made the flag official at Tafira
