Euphemia was the daughter of Grand Prince Vladimir II Monomakh of Kiev and his second wife, whose name and ancestry are unknown.[3] She was married to King Coloman of Hungary around 1112, when she was noted as being a teenager.[4][2] However, her husband, who had been suffering from a serious disease, caught her in adultery and immediately sent her back to Kiev.[5][6] Euphemia gave birth to her son, Boris (1113 – 1155–1156), in her father's court, but the son was never recognised by King Coloman.[7] Afterwards, she lived in a monastery near Kiev till her death, maintaining high status and respect despite the circumstances of her reputation.[2] She was buried in the Church of the Holy Savior in Berestovo (which is within present-day Kiev).[2]
