Persian people
Slaves are attested in the cuneiform record of the ancient Elamites, a non-Persian people who inhabited modern southwestern Iran, including the ancient cities of Anshan and Susa, and who were eventually incorporated into the Achaemenid Empire. Because of their participation in cuneiform culture, the Elamites are one of the few pre-Achaemenid civilizations of Iran to leave written attestations of slavery, and details of slavery among the Gutians, Kassites, Medes, Mannaeans, and other preliterate peoples of Bronze Age Iran are largely unrecorded.
