Most Algerians are of Arab or Berber origin, the Arab ethnic presence in the country is mainly due to the Phoenicians and Hilallians migratory movements (3rd century BC and 11th century, respectively). However, the majority of Arabized Berber claims an Arab heritage, which is a consequence of the Arab nationalism of the early 20th century. The Berbers are divided into many groups with varying languages. The largest of these are the Kabyles, who live in the Kabylia Mountains east of Algiers, the Chaoui of North-East Algeria, and the Tuaregs in the southern desert. Another historical migratory movements that made the actual Algerians was the Vandalic invasion of the 5th century,[84] and the Mediterranean trade of the 16th-19th century.
There is also a minority of about 600,000 to 2 million Algerian Turks who arrived in the region during the Ottoman colonization of North Africa; today's Turkish descendants are often called "Kouloughlis" which means the descendants of Turkish men and of native Algerian women.
