Igor Svyatoslavich
Igor Svyatoslavich the Brave (3 April 1151 – c. 1201), son of Sviatoslav Olgovich of Chernigov, was prince of Putivl, Novgorod-Seversk (1180–1198) and finally Chernigov (1198–1201/1202).
In 1185, without Kiev's leave, he led a campaign against the Cumans raiding southern Rus': after an opening success his army was destroyed on the Kaiala River and he was captured, later escaping. His ill-fated expedition became the subject of the epic Tale of Igor's Campaign. His wife was Yaroslavna of Halych.
