Yaropolk I of Kiev

Yaropolk I Sviatoslavich (also translitered as Iaropolk Svyatoslavich; Old East Slavic: Ꙗрополкъ Свѧтославичъ; 958 – 11 June 978) was Prince of Kiev from 972 to 978. He was the oldest son of Sviatoslav I. Some modern sources suggest that his mother was Malusha, who was a steward in the household of his grandmother, Olga of Kiev. However, primary chronicles such as the Primary Chronicle do not name his mother, and this identification remains unconfirmed by early sources.
