Khanate of Khiva
In 1717, Russian Prince Alexander Bekovich-Cherkassky landed and established a secret fortified settlement on this location, where the dry bed of a former mouth of the Amu-Darya River once emptied into the Caspian Sea. His intent was to march an army up this dry riverbed and conquer the Khanate of Khiva. The expedition failed, and the Russians abandoned the settlement for over 150 years.
