Yaropolk Izyaslavich (died 1087) was a Knyaz (prince) in eleventh-century Kievan Rus. The son of Grand Prince Izyaslav Yaroslavich by a Polish princess named Gertruda, he is visible in papal sources by the early 1070s but largely absent in contemporary Rus'ian sources until the year of his father's death, 1078. During his father's exile in the 1070s, Yaropolk can be found acting on his father's behalf in an attempt to gain the favor of the German emperors and the court of Pope Gregory VII. Yaropolk followed his father when the latter returned to Kiev in 1077.
After his father's death in the following year, 1078, Yaropolk was appointed Prince of Vladimir-in-Volhynia and Prince of Turov by the new Grand Prince, his uncle Vsevolod. By 1085 however, Yaropolk had fallen into a state of enmity with the Grand Prince and by extension the Grand Prince's son Vladimir Monomakh, forcing him to flee from his principality to his mother's homeland, Poland. He returned in the following year, but was soon murdered. He was remembered in Rus'ian sources as extremely pious and generous to the church, and is recognized as a saint in the Eastern Orthodox Church. He was said to have left all his wealth to the Monastery of the Caves in Kiev. The Primary Chronicle's eulogy is the first indication of saintly regard, and indeed today he is venerated as a saint in the Eastern Orthodox Church, with his feast day falling on the reported day of his death, November 22.
