Eudoxia Iziaslavna of Kiev (, , ; c. 1131 – c. 1187), was a Kievan Rus' princess member of the Izyaslavichi of Volhynia and by marriage Duchess of Greater Poland and since 1173 High Duchess of Poland. According to some historians she was the daughter of Iziaslav II, Grand Prince of Kiev by his first wife Agnes (perhaps renamed Lyubava), daughter of King Conrad III of Germany. Life In 1154, Eudoxia married Mieszko III the Old, Duke of Greater Poland, who had recently lost his first wife, Princess Elisabeth of Hungary. With this union, Mieszko III probably wanted to cement his relations with the Izyaslavichi of Volhynia. During her marriage, Eudoxia bore her husband five children, three sons —Bolesław, Mieszko the Younger and Władysław III Spindleshanks— and two daughters —Salomea (Princess of Pomerania) and Anastasia (Duchess of Pomerania)—.
