[2] The Russo-Kazan War of 1505–1507 was a conflict between the Grand Duchy of Moscovite Rus' and the Khanate of Kazan.
It began when Mohammad Amin, who had been installed on the Kazan throne by Moscow, broke his allegiance and launched attacks on Russian merchants.
[citation needed] Expecting vengeance, Mohammad sent 40000 Tatars and 20000 Nogais against Nizhny Novgorod and Murom.
[citation needed] Early in the following year, the prisoners were released except for those who had already been sold to Crimea or central Asia.
[citation needed] This conflict was one of the final chapters of the Russo-Kazan wars, which were part of a broader struggle for control over the Volga region.
The Russo-Kazan War of 1505-1507 also highlighted the growing tensions within the region, leading to a prolonged period of instability in Kazan and influencing Moscow's future strategies in the area.
