Mstislav Sviatopolkovich

Mstislav Sviatopolkovich was a Rurikid prince, apparently the eldest son of Sviatopolk II of Kiev, born to a mistress. In 1099 his father seized Volodymyr-Volynskyi from David Igorevich and installed Mstislav as its prince.

David returned and besieged the town, and on 12 June 1099 Mstislav was struck by an arrow on the city walls and died. Kyiv Caves Monastery accounts portray his death as vengeance for monks he had killed over Varangian treasure.
