For years the Khanates of Kazan and Astrakhan routinely raided Rus principalities for slaves and to plunder towns. Russian chronicles record about 40 raids of Kazan Khans on the Russian territories in the first half of the 16th century. Muscovy was also being invaded by the Nogai Horde and Crimean Khanate which were successors of the Golden Horde.
