Unhappy marriage
On 29 September 1341 in Poznań, Adelaide married Casimir III the Great, King of Poland. The marriage was result of agreement between Casimir III and Luxemburgs. Casimir had no male heir, though he had two daughters, Elizabeth and Kunigunde.
On 29 September 1341, Adelaide was crowned in Poznań Cathedral.
Annulment
Their loveless marriage lasted until 1356. Christina was the widow of Miklusz Rokiczani, a wealthy merchant.
The bigamy and his womanizing Casimir got into severe trouble with the clergy. Casimir continued living with Christina despite complaints by Pope Innocent VI on behalf of Adelaide.
They had no children.
The marriage to Adelaide was annulled in 1368. This marriage produced another three daughters. With Adelaide still alive and Christina possibly as well, the marriage to Jadwiga was also considered bigamous.
The legitimacy of the three last daughters was disputed.
Jadwiga the younger was legitimatized by Pope Gregory XI on 11 October 1371. She spent the rest of her life in Hesse.
She intervened in this case to the pope Greogry XI. On 26 May 1371 pope urged king Louis to give back her property.
