History 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. Karshi developed steadily from the 14th century. During the Sheyban dynasty the town grew violently (16th century). It was the second largest town of Bukhara Khanate in the 18th century. During these centuries much of the city's magnificent architectural monuments were built. With the decline of Shahrisabz in the 18th century, Qarshi grew in importance, and was the seat of the Crown Prince to the Emirate of Bukhara. The city had a double set of walls, 10 caravanserais and 4 madrassahs during this time. By 1868, the Russians had annexed the Zarafshan Valley, and in 1873, the treaty turning Bukhara into a Russian protectorate was signed in Qarshi, much to the dismay of the Emir's son, Abdul Malik, who took to the hills in rebellion. In the early 1970s, the first section of a major irrigation project was completed to divert water from the Amu Darya River in Turkmenistan eastward into Uzbekistan in order to irrigate the land surrounding Qarshi. Almost all of these irrigated lands around Qarshi are planted with cotton. Main Sites Odina Mosque Odina Mosque was built in the 16th century and is on the southeast side
