Languages of Iran
Although, after the Arab invasion of Persia in the 7th century, many Arab tribes settled in different parts of Iran, it is the Arab tribes of Khuzestan that have retained their identity in language and culture to the present day and there was a great influx of Arab-speaking immigrants into the province from the 16th to the 19th century, including the migration of the Banu Kaʿb and Banu Lam.
