Igor of Kiev

Igor launched a naval attack on Constantinople. The Byzantine fleet, using Greek fire, destroyed most of Igor's ships. The campaign failed, forcing Igor to retreat and later negotiate a less favorable treaty in 944.

Following his failed campaign, Igor signed a treaty with the Byzantine Empire. The treaty renewed trade relations but imposed restrictions on Rus merchants and required Igor to provide military assistance to Byzantium.

Igor attempted to collect excessive tribute from the Drevlians, an East Slavic tribe. The Drevlians rebelled, captured Igor, and killed him by tying him to bent trees that tore his body apart. His death triggered Olga's revenge.
