Elisabeth of Greater Poland (Polish: Elżbieta Mieszkówna; Czech: Eliška Polská) (c. 1152 – 2 April 1209) was a Polish princess of the House of Piast and, by her two marriages, Duchess of Bohemia and Margravine of Lusatia.
She was a daughter of Mieszko III the Old, Duke of Greater Poland and from 1173 High Duke of Poland, by his first wife, Elisabeth, daughter of King Béla II of Hungary.[1]
Elisabeth's birthdate is unknown. Medieval sources do not even indicate whether the Hungarian princess was her mother. Elizabeth is believed to have been her daughter only because both had the same name.[2] Some scholars report that Elizabeth was born about 1152[3] or 1154.[4]
