[6][7] The presence of Arabs in Iran dates back to the 7th-8th centuries AD, where under the Sasanian Empire, Mesopotamian Arabs were an important segment of the empire's population along and west of the lower Euphrates river in southern Iraq and between the Tigris and Euphrates in northern Iraq.
This stretch included Arvand Rud, which meets at the current Iran–Iraq border, down to its mouth, where it discharges into the Persian Gulf.
But ethno-linguistic characteristics of the region must be studied against the long and turbulent history of the province, with its own local language khuzi, which may have been of Elamite origin and which gradually disappeared in the early medieval period.
There were attempts by the Iraqi Hussein regime during the Iran–Iraq War (1980–88) to generate Arab nationalism in the area but without any palpable success.
[17] The high ratio of haplogroup F genetically relates Iranian Arabs to Eastern Mediterraneans and the people of the Barbary Coast.
An elevated frequency of haplogroup J-M172 is typical of Near Eastern people and reflective of the genetic legacy of early agriculturalists in the Neolithic Near East c. 8000–4000 BCE.
North of the lands of the ʿAnāfeja of the Āl Katīr, in the area called Mīānāb, between the Kārūn and Karkheh Rivers, dwell several Arab tribes, of which the best known are the Kaab (probably an offshoot of the Banī Kaʿb of southern Khuzestan), the ʿAbd al khānī, the Mazraa, the Al Bū Rāwīya, and the Sādāt.
[25] Women's scarves have various types including Aba that is a black Chador with long sleeves from which hands are only exposed from wrist.
[26] Khamseh Arab nomads live in eastern Fars province (From Lar and close surrounding areas to Khorrambid and Bavanat).
[citation needed] Khorasani-Arabs in the cities Birjand, Mashhad and Nishapur are a small ethnic group but most are Persianized.
