Historically, this symbol was used in Volga Bulgaria and the Khanate of Kazan (Qazan) – predecessors of Tatarstan – as a state symbol. The snow leopard symbol comes from the totems of one of the Bulgar tribes – the Barsil. According to legend, the Barsils founded Bilär in Volga Bulgaria.

The creator of the current emblem is the artist Rif Fäxretdinov (Риф Фәхретдинов).
