Proto-Berber language reached the stage where these different branches of this language family evolved. From that perspective, Proto-Berber was the first Berber stage to depart from Proto-Afrosiatic in the eighth millennium. It was restructured several times during the almost 10,000 years that separated it from its modern shape, which has preserved few relics. Roger Blench (2018) suggests that Proto-Berber speakers 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
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)
