Svyatoslav Vseslavich
Svyatoslav Vseslavich (Christian name Georgy; died after 1129) was a Rurikid prince of Polotsk, one of the younger sons of Vseslav Briachislavich. When the Polotsk land was divided on his father's death in 1101, he may have received Vitebsk, as historians infer from his grandsons' rule there. His daughter Predslava became the monastic saint Euphrosyne of Polotsk.
In 1129 Mstislav Vladimirovich of Kiev campaigned against Polotsk, captured Svyatoslav and exiled him to Constantinople, where all trace of him is lost.
