In 1873, the Khanate of Khiva was much reduced in size and became a Russian protectorate. Following the Russian Revolution of 1917, Khiva had a revolution too, and in 1920 the Khanate was replaced by the Khorezm People's Soviet Republic. In 1924, the area was formally incorporated into the Soviet Union and today is largely a part of Karakalpakstan, Xorazm Province in Uzbekistan, and Dashoguz velayat of Turkmenistan.
