Etymology

Also in Kazan there is a famous "Kaban Lake" similar to the name of the "Kuban River" - which translates from Nogai as "overflowing". The name originated in the 14th century with the Kipchak Tatars who came to these places, especially Astrakhan Nogais. The main now central Bauman Street that leads to the Kremlin is one of the oldest streets in Kazan. In the era of the Kazan Khanate, it was called the Nogai district.
