In August 1570, a Russian envoy in Crimea reported that the Kazakhs had defeated the Altyul Nogais who roamed in the region of Emba.
On August 20, Ofonasy, Fedor, Ivan, and Nikifor were told by Pyotr Ibakov, Sobanya Rezanov, the Nogai Seundyukov, and Bigildey Razgozin that a Nogai Tatar named Devey, a man of Ak-Murza, had arrived from Azov to the Tsar.
Apparently, the Horde lost its former rulers, who were forced to leave these lands.
Based on this data, it can be assumed that the defeat of the Altyuly Horde took place in the summer of 1570, although it is possible that the event occurred earlier and news of it reached contemporaries with the typical delay of that time.
In 1570, Khakk-Nazar Khan defeated the Altyuly, after which some of them migrated to the Nogais on the Yaik River.
