Vladimir II Yaroslavich
Vladimir Yaroslavich (1151–1199), the legitimate son of Yaroslav Osmomysl, was the last Rostislavichi prince of Halych. In 1187 his father left the throne to his illegitimate son Oleg; Vladimir seized Halych with boyar support, only to be driven out, and the struggle drew Hungary and Poland into civil war.
He fled to King Béla III of Hungary, who jailed him and gave Halych to his son Andrew. He escaped to Germany and returned in 1189 with backing from Emperor Frederick Barbarossa; his uncle Vsevolod the Big Nest's protection brought stability. He ruled until his death in 1199, after which Roman the Great of Volhynia seized Halych.
