Khorezm People's Soviet Republic in the context of "Tajik Autonomous Soviet Socialist Republic"

Khiva (Uzbek: Xiva, Хива, خیوه; other names) is a district-level city of approximately 93,000 people in Khorazm Region, Uzbekistan. According to archaeological data, the city was established around 2,500 years ago.

In 1997, Khiva celebrated its 2500th anniversary. It is the former capital of Khwarezmia, the Khanate of Khiva, and the Khorezm People's Soviet Republic. Itchan Kala in Khiva was the first site in Uzbekistan (and in Central Asia) to be inscribed on the World Heritage List (1991). The astronomer, historian and polymath, Al-Biruni (973–1048 CE) was born in either Khiva or the nearby city of Kath.

Karakalpak Autonomous Oblast was created on February 19, 1925 by separating lands of the ethnic Karakalpaks from the Turkestan Autonomous Soviet Socialist Republic and Khorezm People's Soviet Republic.

Initially located within the Kirghiz Autonomous Socialist Soviet Republic (which was later renamed to Kazakh Autonomous Soviet Socialist Republic), the Karakalpak AO was transferred to the Russian Soviet Federative Socialist Republic from July 20, 1930 to March 20, 1932, at which time it was elevated to the Karakalpak Autonomous Soviet Socialist Republic (Karakalpak ASSR). The Karakalpak ASSR was joined to the Uzbek SSR from December 5, 1936.

The Khanate of Khiva (Chagatay: خیوه خانلیگی, romanized: Khivâ Khânligi, Persian: خانات خیوه, romanized: Khânât-e Khiveh, Uzbek: Xiva xonligi, Хива хонлиги, Turkmen: Hywa hanlygy, Russian: Хивинское ханство, romanized: Khivinskoye khanstvo) was an Uzbek monarchy that existed in the historical region of Khorezm from 1511 to 1920, except for a period of Afsharid occupation by Nader Shah between 1740 and 1746. Centred in the irrigated plains of the lower Amu Darya, south of the Aral Sea, with the capital in the city of Khiva. It covered present-day western Uzbekistan, southwestern Kazakhstan and much of Turkmenistan before the Russian conquest at the second half of the 19th century.

In 1873, the Khanate of Khiva was greatly reduced in size and became a Russian protectorate. The other regional protectorate that lasted until the Revolution was the Emirate of Bukhara. 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 it is largely a part of Karakalpakstan, Xorazm Region in Uzbekistan, and Daşoguz Region of Turkmenistan.
