Olga is also known to have requested a bishop and priests from Rome. Her son, Sviatoslav (r. 963-972), continued to worship Perun and other gods of the Slavic pantheon. He remained a stubborn pagan all of his life; according to the Primary Chronicle, he believed that his warriors would lose respect for him and mock him if he became a Christian. Sviatoslav's successor, Yaropolk I (r. 972-980), seems to have had a more conciliatory attitude towards Christianity. Late medieval sources even claim that Yaropolk exchanged ambassadors with the Pope. The "Chronicon" of Adémar de Chabannes and the life of St. Romuald (by Pietro Damiani) actually document the mission of St. Bruno of Querfurt to the land of Rus', where he succeeded in converting to Christianity a local king (one of three brothers who ruled the land). Alexander Nazarenko suggests that Yaropolk went through some preliminary rites of baptism, but was murdered at the behest of his pagan half-brother Vladimir (whose own rights to the throne were questionable) before his conversion was formalized. Following this theory, any information on Yaropolk's baptism according to the Latin rite would be suppressed by the later Orthodox chroniclers, zealous to keep Vladimir's image of the Rus Apostle untarnished for succeeding generations. During the first decade of Vladimir's reign, pagan reaction set in. Perun was chosen as the supreme deity of the Slavic pantheon and his idol was placed on the hill by the royal palace. This revival of paganism was contemporaneous with similar attempts undertaken by Jarl Haakon in Norway and (possibly) Svein Forkbeard in Denmark. His religious reform failed. By the late 980s he had found it necessary to adopt monotheism from abroad. The "Primary Chronicle" reports that, in the year 986, Vladimir met with representatives from several religions. The result is amusingly described in the following apocryphal anecdote. Upon the meeting with Muslim Bulgarians of the Volga, Vladimir found their religion unsuitable due to its requirement to circumcise and taboos against alcoholic beverages and pork; supposedly, Vladimir said on that occasion: "Drinking is the joy of the Rus." He also consulted with Jewish envoys (who may or may not have been Khazars), questioned them about Judaism but ultimately rejected it, saying that their loss of Jerusalem was evidence of their having been abandoned by God.
