Sarts was a name for various sedentary Turkic tribes of Turkistan that settled by Syr Darya, known as Ak-sart in old times. Sarts did not have any particular ethnic identification. The term was used as early as in the Turkic book Kudatku Bilik ("Blessed Knowledge") dated by 1070. In literature of Imperial Russia the term was used to denote Turkic-speaking people of Bukhara, Samarkand and Ferghana areas.

Eventually they were assimilated into Uzbeks.
