Sharukan’ (from http://encyclopedia2.thefreedictionary.com/Sharukan), a city of the 11th to early 13th centuries apparently located on the Severskii Donets near the cities of Chuguev and Zmiev. Sharukhan’, whose name derives from that of the Polovtsian khan Sharukan, arose as an Alani settlement. The city had an ethnically mixed population and served as the winter refuge of the Polovtsy. In 1111 it was captured by troops under the command of Vladimir Vsevolodovich Monomakh and other Russian princes. During the 12th and early 13th centuries, Sharukan’ was gradually abandoned.
