 The Maghreb today is home to large Berber (Amazigh) populations, who form the principal indigenous ancestry in the region (see Origins).The Semitic ethnic presence in the region is mainly due to the Phoenicians, Jews and Arab Bedouin Hilallians migratory movements (third century BC and eleventh century, respectively) which mixed in.However, the majority of Arabized Berbers, particularly in Morocco and Algeria, claim an Arabian heritage; this is a consequence of the Arab nationalism of the early twentieth century.
