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
Ethnic flag of Ararat (1927). A flag of the Hispanic People was designed in 1932. Alternatively, an "ethnic flag" may represent a Pan-nationalism, such as the Pan-Arab flag which originates as the flag of the Arab Revolt during World War I, the proposed flag of Pan-Slavism (1848), Pan-Iranism or Pan-Turkism. The concept of using ethnic flags to symbolize ethnic groups within a multiethnic state, not necessarily connected with irredentism, became popular in the later 20th century, such as the Australian Aboriginal flag (1971), the Assyrian flag (1971), the flag of the Romani people (1971), the Berber flag (1970s), the Sami flag (1986)
