The Bulavin Rebellion (Astrakhan Revolt) is the name given to a war of Don Cossacks against Imperial Russia between the years 1707 and 1708. The war was led by Kondraty Bulavin, a democratically elected Ataman of Don Cossacks. The war was triggered by a number of underlying tensions between the Imperial government under Peter I of Russia, the Cossacks, and Russian peasants fleeing from serfdom in Russia to gain freedom in the autonomous Don area. It started with the assassination of Prince Yury Dolgorukov, the leader of Imperial army's punitive expedition to the Don area, by Don Cossacks under Bulavin's command. The end of the rebellion is associated with Bulavin's death in 1708.
