Since Bolesław's arrival at the Bohemian court and after his betrothal to Margaret, the King clearly favored him; this attitude caused fear between the closest male relatives of the King, who saw the young Duke of Legnica as a potential rival for the throne.
Although Wenceslaus II had a son who seemed to render him irrelevant, the sudden death of the King in 1305 and one year later the murder of his son and successor Wenceslaus III in Olomouc gained him an unexpected importance.
Bolesław began his fight for the Bohemian throne taking the title of "haeres Regni Poloniae" (heir of the Polish Kingdom).
Instead, Elisabeth married John of Luxembourg who overthrew Henry and Anna once and for all.
Margaret died one day after giving birth to her youngest child.
