Roman the Great
By 1130, all descendants of Vseslav the Seer had been exiled to the Byzantine Empire by Mstislav the Great. The most fierce resistance to the Monomakhs was posed by the Olegovichi when the izgoi Vsevolod II managed to become the Grand Prince of Kiev. The Rostislavichi who had initially established in Halych lands by 1189 were defeated by the Monomakh-Piast descendant Roman the Great.
