Siberia Khanate
In the 1440s, the Golden Horde was racked by civil war. It broke up into four separate Khanates: the mighty Khanate of Kazan, the Khanate of Astrakhan, the Khanate of the Crimea which would become tributary to the Ottoman Turks and the remote and weak Siberia Khanate, which is an anachronistic rendering of its actual name Khanate of Sibir.
The main population was Siberian Tatars.
Some parts of Khanate also included Sibir Duchy that exist in 14th century at the North of Golden Horde, Mansi, Khanty and Nenets lands.
Conquered by Russian cossacks under Yermak Timofeyevich in 1570s.
The rulers of the territory (khans) were usually selected from descendants of Shayban, Batu's brother. The last khan of Siberia was Kuchum, whose descendants have been known as Princes Sibirsky.
The last capital was Qashliq.
Many modern Russian cities of West Siberia were founded at Siberia Khanate period (Tyumen, Tobolsk).
The Siberian khanate was easily overrun by the Russians as they explored and subdued the sparsely populated vast subcontinent they named Siberia after Sibir. In a sense, the khanate lived on in the subsidiary title "Tsar (i.e. King) of Siberia" which became part of the full imperial style of the Russian Autocrats.
