The Primary Chronicle names Sviatopolk son of Iziaslav, recording that his father established him as Prince of Polotsk in 1069 after the death of his brother Mstislav. He was appointed to succeed his brother Mstislav as Prince of Polotsk in 1069, but was expelled by his predecessor Prince Vseslav in 1071.
He was installed as Prince of Novgorod in 1078 by his uncle Vsevolod Grand Prince of Kiev, but transferred to Turov in 1088, relinquishing the latter in 1093 when he succeeded his uncle as SVIATOPOLK II Grand Prince of Kiev. His possession of Kiev was confirmed in 1097 under the family accord at Liubech, which distributed the various family territories. This was followed by the conference at Uvetichi 30 Aug 1100, at which further distributions were made. After years suffering from raids by the Kuman [Cumans], he made peace in 1101 at Sakov near Pereyaslavl, but carried out the first of a series of counter-offensives against them in 1103. 1
