乌兹别克苏维埃社会主义共和国
Following the Bolshevik seizure of power in Russia after the October Revolution of 1917, a short-lived (1920-1925) Khorezm People's Soviet Republic formed out of the territory of the old Khanate of Khiva before its incorporation into the USSR in 1925. The city of Khiva became part of the Uzbek Soviet Socialist Republic.
