Mstislav II Iziaslavich (died 19 August 1170) was Grand Prince of Kiev from 1158 to 1159 and again from 1167 to 1169.[1]
Mstislav was the son of Grand Prince Iziaslav II of Kiev. Along with his father, he participated in the wars against Yury Dolgoruky and the Chernigov princes. After an initial victory against the Cumans in 1153, Mstislav was defeated by the Cumans at the Psel river. Yury Dolgoruky forced him to flee to Poland in 1155, but the next year Mstislav returned with a new army and defeated Dolgoruky at Vladimir-Volynsk. Dolgoruky died in 1157, and Mstislav had himself crowned at Vladimir.
In 1169, Kiev was sacked by Andrey Bogolyubsky who removed Mstislav as grand prince.[2] Mstislav passed his exile in Byzantium and during the reign of Emperor Manuel I Komnenos, was rewarded the district of Otskalana.[3]
In 1151, Mstislav married Agnes, the daughter of Duke Bolesław III of Poland.[4] They had three sons:
