She was a daughter of Duke Vratislaus II of Bohemia and Adelaide of Hungary, and was married to Władysław Herman.

Around 1080, Judith married Duke Władysław Herman of Poland to solidify the recently established Bohemian-Polish alliance.

[5][6] According to contemporary chroniclers, Duchess Judith performed remarkable charity work, helping the needy and ensuring the comfort of subjects and prisoners.

[7][8][9] After almost five years of childless marriage, the necessity for an heir increased:[10][11] On 10 June 1085, Judith and her husband were present at the coronation of her father, Vratislaus II, as the first king of Bohemia.

One year later, on 20 August 1086, she gave birth to the long-awaited son and heir, Bolesław Wrymouth.
