 On 13 December 1350, 11-year-old Anna and the then 11-month-old Wenceslaus, eldest son and heir of Emperor Charles IV, were betrothed.Under the terms of the engagement contract, the couple would inherit Bolko II's lands in the (likely) case of his heirless death (however, it was stipulated that they could only take formal possession of the duchies after the death of Bolko II's wife Agnes of Austria, who, under her husband's will, received his domains as her ).However, fifteen days later, on 28 December, the young Wenceslaus died and the settlement was broken.
