Daughter of Bolesław I the Brave (967-1025) was born 995 to Bolesław I the Brave (967-1025) and Emnilda and died 1018 of unspecified causes. She married Svyatopolk I Vladimirovich of Kiev (c980-1019) .
Bolesław, who already had two wives, wanted to marry Predslava, one of Vladimir's daughters]], in order to cement ties between the two families. Despite Bolesław's best efforts, the offer was refused and instead he had to accept a less prestigious connection to the house of Vladimir through the marriage of Bolesław's daughter to Vladimir's son, Svyatopolk. Between 1005 and 1013, Vladimir arranged Svyatopolk's marriage to Bolesław's daughter, whose name has not survived in sources.
