Zuṭṭ

Zuṭṭ (also as Zatt and Zott) is an Arabicised form of Jat. Originally inhabitants of lower Indus Valley, Jats were present in Mesopotamia since as early as 5th century AD, although their main migration occurred after the establishment of Umayyad Caliphate. They were one of the prominent ethnic groups in lower Iraq during Islamic Golden Age, supplying mercenary soldiers to the Muslim states. Their mention fades from Muslim chronicles after 11th century.
