Oleg's date of birth is not known, but it is probably before 957. Sviatoslav split up his domains, and gave the Drevlian lands to Oleg in 970. Oleg and his brother
Yaropolk went to war after their father's death. According to the
Primary Chronicle, Oleg killed Lyut, the son of Yaropolk's chief adviser and military commander
Sveneld, when he hunted in the Drevlian lands which Oleg regarded as his own. In an act of revenge and at the insistence of Sveneld, Yaropolk went to war against his brother Oleg and killed him in
Ovruch. Oleg was killed incidentally on the run in moat, and Yaropolk did regret this. Then, Yaropolk sent his men to
Novgorod, from which his other brother
Vladimir had fled on receiving the news about Oleg's death. Yaropolk became the sole ruler of
Kievan Rus'. In 1044,
Yaroslav I the Wise had Oleg's bones exhumed, christened, and reburied in the
Church of the Tithes. == Possible descendants ==
