Mstislav I of Kiev

Mstislav Vladimirovich (1076–1132), called the Great, was the eldest son of Vladimir Monomakh. He ruled Novgorod from 1095 to 1117, served as his father's co-ruler, and succeeded him as grand prince of Kiev in 1125. In 1096 he defeated his father's cousin Oleg of Chernigov on the Koloksha river.

As grand prince he campaigned against Polotsk, the Cumans and Lithuanians. By his Swedish wife Christina his daughters married the kings of Norway and Denmark. When he died on 14 April 1132, the chronicler wrote, the land of Rus was torn apart.
