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 kings of Roman-era Tunisia from Tripolitania westward. Although within a commercial sphere dominated by Carthage, most Berbers lived in territories outside its direct political control. Comparatively little is known of the most ancient Berber peoples since the few surviving writings from Carthage shed little light on this history, although surviving inscriptions and artifacts do offer some clues and hints. Starting with the Punic Wars, Berbers are, however, mentioned in surviving works of classical Greek and Roman authors and these sources provide some details in the descriptions of Berber events. During the three Punic Wars, Rome directly entered into permanent relations with the Berber people.
