"the land of Rus was torn apart".

"Mstislav I Vladimirovich the Great (Russian: Мстислав Владимирович Великий,(June 1, 1076 – April 14, 1132) was the Grand Prince of Kiev (1125–1132), the eldest son of Vladimir II Monomakh by Gytha of Wessex.

 He is figured prominently in the Norse Sagas under the name Harald, to allude to his grandfather, Harold II of England. Mstislav's Christian name was Theodore.

Mstislav was the last ruler of united Rus, and upon his death, as the chronicler put it, "the land of Rus was torn apart". He died in Kiev, aged 55.

In 1095, Mstislav married Princess Christina Ingesdotter of Sweden, daughter of King Inge I of Sweden. They had many children:"
