Sviatoslav I of Kiev
Born in 958, Vladimir was the natural son and youngest son of Sviatoslav I of Kiev by his housekeeper Malusha. Malusha is described in the Norse sagas as a prophetess who lived to the age of 100 and was brought from her cave to the palace to predict the future. Malusha's brother Dobrynya was Vladimir's tutor and most trusted advisor. Hagiographic tradition of dubious authenticity also connects his childhood with the name of his grandmother, Olga of Kiev, who was Christian and governed the capital during Sviatoslav's frequent military campaigns.
