Yaroslav Iziaslavych [Ярослав Ізяславич; Jaroslav Izjaslavyč], b ?, d ca 1180. Prince of Turiv, Novgorod the Great, Volodymyr-Volynskyi, and Lutsk; son of the Kyivan prince Iziaslav Mstyslavych and brother of Mstyslav Iziaslavych. In 1173–4, aided by the Rostyslavych family, he controlled the Kyivan throne (see Kyiv principality) and extracted heavy tributes from the population, including the clergy, monasteries, and resident foreign merchants. The burden he imposed aroused considerable hostility, and Yaroslav was deposed. In Lutsk he contributed to the establishment of a local eparchy. He married the daughter of the Czech king Vladislav II.
