Ногайская Орда
In 1221, the Mongols occupied it. It was later passed to successively Golden Horde, Nogai Horde, Uzbek Khanate and Kazakh Khanate, but its population decreased after gradual drying of the steppe and Kalmyk raids began in 1620. Some Salur and Ersari Turkmens left the region and migrated to Russia.
