In the book, for the first time in world science, a monographic study of the history of the Astrakhan Khanate (1502-1556), one of the states formed as a result of the collapse of the Golden Horde, was carried out. As a result of a comprehensive analysis of Russian, Eastern (Arab, Turkic, Persian) and Western sources, the date of the formation of the khanate was substantiated, a chronology of the reign of the Astrakhan khans was proposed.
