Rostislav Vladimirovich[1][a] (c. 1038 – 3 February 1066) was a landless prince (izgoi) from the Rurikid dynasty of Kievan Rus’.
Under the East Slavic house law, the early death of Rostislav's father made his descendants forfeit all claims to Kiev.
Finally, his uncles gave him Volhynia and Galicia, where he stayed from 1057 and 1064, guarding the western frontier of the Rus' lands.
Rostislav did not like the distant and meager land and, in 1064, assisted by his father's close friend Vyshata, seized the rich Tmutarakan on the Black Sea littoral, previously controlled by the House of Chernigov.
His predecessor, Gleb Svyatoslavich, escaped to his father, Svyatoslav II of Chernigov who was part of the Yaroslaviches triumvirate.
