Kondraty Bulavin the elected Ataman of the Cossacks. Who gave his name to the The Bulavin Rebellion – 1707-1708 a war between the Cossacks and Imperial Russia.
The War was triggered by a number of underlying tensions between the Imperial government of Russia under Peter I and the Cossacks.
It started with the assassination of Prince Dolgorukov, the leader of The Russian Imperial army's expedition to the Don area. The Cossacks ambushed and murdered Dolgoruki and his men in the village of Shulgin on the Aidar River, opening the door to violence and beginning the Bulavin Rebellion.
The rebellion suffered from a number of weaknesses. For one, despite all of his rallying, Bulavin never offered a pretender to the throne or suggested a just tsar to replace Peter. This blunder would condemn the rebellion's end goals to ambiguity and would let slip an immeasurable amount of support he might have mustered. Second, Bulavin did not coordinate his efforts with any other pre-existing Muscovite enemies.
The military apparatus under Peter was not as divided as it could have been and found the rebellion to be more of a nuisance than a major conflict. By means of its vastly superior size and efficiency, the regular army was ultimately capable of stamping out the rebellion at all levels. In the end, angered by devastating reversals and Bulavin's tiring claims, factions of his own Cossack followers turned against him. He was found dead on July 7, 1708, having been shot in the head. It is not known whether the wound was self-inflicted or an act of treachery. Following Bulavin's death, the rebellion petered out, with pockets of resistance persisting through 1709, but for all intents and purposes, the conflict was over.
