"Show me just what Mohammed brought that was new, and there you will find only things evil and inhuman, such as his command to spread by the sword the faith he preached." - Manuel II Palelogus
Tatarstan is part of Russian Federation (see green #13 on the map.) Its borders are merely lines on the map and there are no troops anywhere close.
Tatars are Muslims, by the way:
Tatarstan was conquered by the troops of Tsar Ivan IV the Terrible in the 1550s, with Kazan being taken in 1552. Some Tatars were forcibly converted to Christianity and cathedrals were built in Kazan; by 1593 all mosques in the area were destroyed. The Russian government forbade the construction of mosques, a prohibition that was not lifted until the 18th century by Catherine II. The first mosque to be rebuilt under Catherine's auspices was constructed in 1766-1770.
As it seems, Russian Empire had some liberal rulers too.
