Iranian Arabs are the Arabic-speaking peoples of Iran. Most Iranian Arabs live in the coastal regions of southern Iran by the Persian Gulf. Iranian Arab communities are also found in Bahrain, Kuwait, Iraq, Qatar, and the United Arab Emirates. The Arab presence in Iran did not begin with the Islamic conquest of Persia in 633 AD. For centuries, Iranian rulers had maintained contacts with Arabs outside their borders, dealt with Arab subjects and client states in Iraq, and settled Arab tribesmen in various parts of the Iranian plateau. It follows that the "Arab" conquests and settlements were by no means the exclusive work of Arabs from the Hejaz and the tribesmen of inner Arabia. The Arab infiltration into Iran began before the Muslim conquests and continued as a result of the joint exertions of the civilized Arabs (ahl al-madar) as well is the desert Arabs (ahl al-wabar).
