Abstract
<jats:p xml:lang="en">The “Syrdarya Region” or “Syr Region’s” geographical definition denotes the Syr Darya River’s lower reaches and the Aral Sea’s eastern shores. The Kazakh tribe’s regional ethnic formation is complex and formed in several historical phases. Its history dates back to ancient ages. It was the Saka-Massagetae’s political-administration center, and Kangui clans’ land during the Early Iron Age. Turkish-origin clans/tribes migrated to the Syrdarya Region and Oghuz and Kipchak states settled there during the Early Medieval Age. The Mongol-Tatar invasion was the next regional migrative movement. The regional Turkic clans/tribes joined the subsequent ethnic formation of the “Kazakh” people. The Syrdarya Region, under the Dzungar invasion, became a large migration center and the home for a complex clan/tribe union with the Greater, Middle, and Lesser tribe Kazakhs. This study covers the history of complex relations between the clan/tribe in the Syrdarya region, which has been a center of commerce since the ancient ages.</jats:p>
