She was the younger daughter of Margrave
Theodoric II of Lusatia and his wife Matilda, daughter of Margrave
Eckard I of Meissen. Ida's father, former Count of
Eilenburg, became
Lusatian margrave in 1032 and was killed by the henchmen of his brother-in-law, Margrave
Eckard II of Meissen on 19 November 1034. Ida was married to the
Přemyslid duke Spytihněv II of Bohemia and gave birth to two surviving children. Together with them she apparently was exiled from Bohemia after the death of her husband on 28 January 1061. Her daughter, whose name is not recorded, married a
Saxon nobleman named Wichmann of
Celle, whereas her son Svatobor (Frederick) became
Patriarch of Aquileia in 1085, only to be murdered during a street disturbance in February 1086. She probably had another daughter, who became the first wife of Grand Prince
Sviatopolk II of Kiev. ==Notes==
