Yaropolk was given
Kiev by his father
Sviatoslav I, who left on a military campaign against the
Danube Bulgars. Soon after Sviatoslav's death, however, civil war began between Yaropolk and his brothers. According to one
chronicle, Yaropolk's brother
Oleg killed Lyut, the son of Yaropolk's chief adviser and military commander
Sveneld. Alternatively, Sveneld is identical to Sviatoslav, as Sveinald/Sveneld is the Norse rendition of the Slavic name. In an act of revenge and at Sveneld's insistence, Yaropolk went to war against his brother and killed him. Yaropolk then sent his men to
Novgorod, from which his other brother
Vladimir had fled upon receiving news of Oleg's death. Yaropolk became the sole ruler of
Rus'. In 980, Vladimir returned with the
Varangian mercenaries and attacked Yaropolk. On his way to Kiev, Vladimir seized
Polotsk because
Rogneda, daughter of the Polotsk prince
Rogvolod, had chosen Yaropolk over him. Vladimir forced Rogneda to marry him. Then, Vladimir seized Kiev with assistance from a boyar, Blud, who had become Yaropolk's chief adviser upon the death of Sveneld. Blud betrayed Yaropolk by advising him to flee from Kiev to the town of
Rodnya at the mouth of the
Ros' River. Vladimir besieged Rodnya and starved Yaropolk into negotiations. Yaropolk trusted Blud's and his brother's promises of peace and left for Vladimir's
headquarters, where he was killed in an ambush by two Varangians. ==Purported baptism==
