Rostislav of Tmutarakan

Rostislav Vladimirovich (c. 1038–1066), baptized Mikhail, was a landless Rurikid izgoi prince, son of Vladimir of Novgorod and grandson of Yaroslav the Wise. His father died before Yaroslav, costing Rostislav his claim to Kiev, and he had no appanage for five years after Vladimir's death.

He held Volhynia and Galicia from 1057, and tradition makes his wife Anna a daughter of King Béla I of Hungary. In 1064, aided by Vyshata, he seized Tmutarakan on the Black Sea, was expelled by Svyatoslav of Chernigov, and then returned to subdue the Circassian Kasogi.

Alarmed by his rise, Byzantine Chersonesos had him poisoned on 3 February 1066. He left three sons, Rurik, Volodar and Vasilko.
