Dozens of alleged arsons were committed along the middle course of this river during a drought in 1839, leading to an outbreak of violence against local authorities by the peasantry. A 10th century traveler along this river observed the burial of a chieftain which involved a young woman having sex with the deceased man's subordinates and then being sacrificed by the "Angel of Death". That traveler, Ahmad ibn Fadlān, wrote an account of his time as an ambassador to Almış ("ahl-moosh"), the first Muslim king of a Turkic state named after this river. (*) Stenka Razin tried to capture the entirety of this river after pillaging a city at its delta. Feodor Chaliapin famously recorded a folksong about this river's boatmen and the cities of Kazan and Astrakhan lay on its banks. For 10 points, identify this principal river of European Russia and the longest in Europe.
