Originally the Sogdian city of Nakhshab (which could be possibly named Eucratideia during the rule of Greco-Bactrian Kingdom), and the Islamic Uzbek (Turkic) city of Nasaf, and the Mongol city of Qarshi (pronounced "Kharsh"), Qarshi was the second city of the Emirate of Bukhara. It is in the center of a fertile oasis that produces wheat, cotton, and silk and was a stop on the 11-day caravan route between Balkh and Bukhara. The Mongol Chagataid khans Kebek and Qazan built palaces here on the site of Chinggis Khaan's summer pasture. In 1364, Timur also built a fortified palace with moats in what is now the southern part of the city. The modern name "Qarshi" means fort.
