UZBEK KHANATE

any of the three states that ruled Transoxania, in present-day Uzbekistan, before it came under Russian rule in the 19th century. The khanates of Bukhara and Khiva (Khwarezm) were established by two branches of the Shaybanid dynasty, which won control of Transoxania from the Timurids in the late 15th and early 16th centuries. The Shaybanids were replaced at Bukhara successively by the Astrakhanids and the Mangits. A third state, the khanate of Kokand, emerged in the mid-18th century. The whole area came under Russian control in the 1860s and '70s, but the khans remained as figurehead rulers until after the Russian Revolution of 1917.
