In a scenario where Vladimir the Great of Kiev adopted Catholicism (or as this is pre-1054, Latin Rite Chalcedonianism would be more accurate) instead of Orthodox Christianity/Greek Rite Chalcedonianism, what would the impact of such a conversion? What would the culture of a Catholic Russia look like? What would be major differences between said Catholic Kievan Rus and OTL's Kievan Rus?
