Igor of Kiev

Igor (c. 877–945) was Prince of Kiev from 912 to 945 and, by tradition, the son of Rurik. Left an infant at his father's death in 879, he grew up under the regency of his kinsman Oleg, who seized Kiev by killing its rulers.

In 941 and 944 Igor led Rus' fleets against Constantinople; Greek fire broke the first attack, and in 945 he made a treaty with Emperor Constantine VII. That year the Drevlians murdered him while collecting tribute a second time, after which his widow Olga took vengeance and the regency.
