Iaroslav Sviatopolkovich

Iaroslav Sviatopolkovich (c. 1072–1123) was a Rurikid prince, the second son of Sviatopolk II, Grand Prince of Kiev. In 1100 his father made him prince of Vladimir-in-Volhynia; in 1102 Novgorod refused to accept him as prince.

He strengthened ties with Hungary through marriage to a daughter of King Ladislaus I, and later wed Rogneda, daughter of Mstislav the Great. After he clashed with Vladimir Monomakh, who took Kiev in 1113, he sent Rogneda away and was driven from Volhynia in 1118.

He fled to Poland and Hungary. In 1123 he returned with their troops to besiege Vladimir-in-Volhynia, where he was killed.
