Sawad was the name used in early Islamic times for southern Iraq. It means "black land" or "arable land" and refers to the stark contrast between the alluvial plain of Mesopotamia and the Arabian Desert. Under the Umayyad and Abbasid Caliphates, it was an official political term for a province encompassing most of modern Iraq except for the Syrian Desert and Upper Mesopotamia in the north.
