アストラハン・ハン国
Khazar invasions forced the Bulgars, Turkic people, to migrate from the Azov steppes to the Middle Volga and lower Kama region during the first half of the eighth century. In the period of 10th–13th centuries, other Turkic peoples, including Kipchaks, migrated from Southern Siberia to Europe. They played a significant role in the Mongol invasion of Rus' in the 13th century. Tatar ethnogenesis took place after migrated Turkic peoples, mixed with the local Bulgar population and other inhabitants of the Volga River area, kept Kipchak dialect and became Muslims. Several new Tatar states had emerged by the 1500s after the Golden Horde fell. These states were Khanate of Kazan, Astrakhan Khanate, Khanate of Sibir and Crimean Khanate.
