Emperor Henry III had waged two unsuccessful campaigns against Hungary in 1051 and 1052, whereafter Pope Leo IX arranged an agreement.
Nevertheless, with the support of his powerful brother-in-law, Solomon could recover the Hungarian throne after the death of his uncle Béla I in 1063 and soon after married with Judith in Székesfehérvár.
Although it is generally believed that the union was childless, some sources state that Solomon and Judith had a daughter, Sophia,[4] who later married Count Poppo of Berg-Schelklingen.
Judith fled back to Germany, while Solomon continued his fight for the Hungarian throne; in 1077 he accepted the rule of his cousin King László I, who gave him in exchange extensive landholdings after his formal abdication (1081).
This union considerably benefited German-Polish relations; on the occasion of the wedding, Emperor Henry IV commissioned to St. Emmeram's Abbey in Regensburg the creation of Gospel Books to the Polish court, now kept in the library of the Wawel Cathedral chapter in Kraków.
(who married Prince Yaroslav Sviatopolkovich of Vladimir-Volynia), Agnes (later abbess of Quedlinburg and Gandersheim), and the wife of a Polish lord whose name is not known.
With the help of Sieciech, Judith convinced her husband[9] to send Władysław I's first-born son Zbigniew (who seems to be a strong candidate to the succession despite his illegitimacy) to Quedlinburg Abbey where her sister Adelaide was abbess; also, they wanted an eventual alliance with the only legitimate son of Władysław I, Bolesław Wrymouth, born from his first marriage with Judith of Bohemia.
Sources established that she died between 1092–1096, but this seems improbable, because is known that around 1105, Bolesław III entered into an agreement with her, under which, in exchange for abundant dower lands, Judith guaranteed her neutrality in the Duke's political contest with his half-brother Zbigniew.
Gerard Labuda stated that Judith spent her last years of life in Regensburg with her (supposed) daughter Adelaide, wife of Count Dietpold III of Vohburg and Cham; since the date of the marriage between Adelaide and Count Dietpold III was ranked between 1110–1118, it is assumed that Judith died after the latter year, at a relatively advanced age.
