Arabisation

Arabization or Arabisation (Arabic: تعريب‎‎ taʻrīb) describes either the conquest of a non-Arab area and growing Arab influence on non-Arab populations, causing their gradual adoption of the Arabic language and/or their incorporation of Arab culture and Arab identity. The religion of Islam and the associated Islamist (government and society ordered in accordance with laws prescribed by Islam) socio-political order, with their central Quran text written in Arabic language and tailored for Arab culture, had a central role in Arabization, which usually went hand in hand with Islamization of conquered lands. Generally, elements of Arabian origin were combined in various forms with elements from conquered civilizations and ultimately denominated "Arab". Arabization also continued in modern times, most prominently being enforced by the Arab nationalist regimes of Iraq,Syria, Sudan,Mauritania, Algeria and Libya with policies which include expanding colonial Arab settlements, expulsion of non-Arab minorities and enforcement of Arab identity and culture upon non-Arab populations, in particular by means of not permitting autochthonous mother tongues other than Arabic in education. The United Nations High Commissioner for Human Rights, citing local witnesses, also claims that the aggressive persecution of non-Arab minorities by the terror group Islamic State of Iraq and the Levant is forced Arabization.
