Iziaslav II of Kiev

Iziaslav II Mstislavich (c. 1096–1154), a son of Mstislav I of Kiev and grandson of Vladimir II Monomakh, ruled several principalities before taking the Kievan throne in 1146.

His reign was dominated by war with his uncle Yuri Dolgorukiy of Suzdalia, who drove him from Kiev in 1149; Iziaslav recovered the capital in 1151 and held it until his death in 1154. He was among the first Rus princes called tsar in the chronicles and founded the Volhynian Iziaslavichi line.
