The collapse of Kazan Khanate constitutes a turning point in respect of the history of the Turkish countries: pursuant to this event, the Idyll (Volga) River was occupied by the Russians. Idyll River that had been considered as a "Turkish River" for a period of 1000 years until that time turned into a "Russian River" from that date on and it started to become the vital point of the Russian economy. The Russians came down towards the south along Idyll River and captured Astrakhan (Ejderhan, Astrahan) and reached to the Caspian Sea. They did not stay there; and they came down towards the Northern Caucasus. Therefore, the first relations between the Ottoman Empire and Russia took place in this region and it caused tension. Upon the warnings obtained from Nogay people and Turkestan, the Ottoman State set in motion to reinvigorate the Kazan and Astrakhan Khanates. Pursuant to the letters written by Sultan Selim II to Ivan IV that were full of threats, a military expedition was organised with the purpose of besieging Astrakhan in the year of 1569; but it was not followed. Due to the defeat of Inebahti in the year of 1571 and the military expedition organised towards Cyprus in the year of 1571, the Ottoman State showed interest in another field and these events caused the Ottoman State to forget the Russian danger for a while. Since they could not obtain any help from the outer sources, Kazan people could not attain any results from the civil rebellions that took place occasionally; and they were abandoned to their own fates thereof.
