Volga Bulgaria was a historic Bulgar state that existed between the 7th and 13th centuries around the confluence of the Volga and Kama rivers, in what is now European Russia. Strategically located along major trade routes, it flourished as a wealthy mercantile power connecting Europe and Asia.
In 922, they formally adopted Islam during the visit of the Baghdad Caliphate embassy, famously detailed by chronicler Ibn Fadlan. According to local legends, the capital Bolghar was protected by a sacred dragon or water snake that nested near the Volga banks, acting as a guardian spirit of the city until it was overrun and destroyed by the Mongols in 1236.
