Iranian Arabs mostly live in Provinces such as Khuzestan and Hormozgan. Arabs of Khuzestan Province, who live in South-west side of Zagros Mountains, along with the bank of the Shatt-al-Arab (Arvand Rood) .Over 3.5 million indigenous Arab people, live in the territory known as al-Ahwaz or Khuzestan and neighbouring provinces
For some 500 years, the region was called Arabistan of Iran by Persian rulers. The central government changed the territory’s name to Khuzestan in 1936. Al-Ahwaz or Khuzestan also borders Iraq, Kuwait and the Persian Gulf

Since 1925, indigenous Ahwazis have been brutalized and deliberately kept backward by the successive regimes of Iran. While their land accounts about 80% of Iranian oil production, they benefit no revenue in return, with half of Ahwazi people in absolute poverty and 80% of Ahwazi children suffering from malnutrition
The Ahwazis have been subjected to the eradication of their national identity, culture, and customs; and are faced with forced assimilation, and imposition of Persian language and culture. Ahwazis like other minorities cannot wear their national and ethnic dresses and costumes in official centres. Therefore, a dominant Persian minority influences in every respect of life, political, social, cultural and economical of not only the Ahwazis but all minority of Iran
