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
Names of the Berber people Names of the Berber people The ethnonym Berber dates to the 19th century, derived from "Barbary" the term for the Maghreb coast used during the early modern period, itself from Greek "barbaria" "land of barbarians".
