Due to the vacancy on the Hungarian throne after the death of Albert I, King of Hungary, the pregnant queen set out for Pozsony (now Bratislava, Slovakia; Pressburg in German) to give birth to the future Hungarian king in the vicinity of the Habsburgs. However, Ladislas the Posthumous was born on route, in Komárom (now Komarno, Slovakia). The queen, having seized the Holy Crown of Hungary, went to Székesfehérvár to have her son crowned there in accordance with the Hungarian customs. Thus, her action preceded the crowning of Wladislas Jagiello, who had been invited to Hungary in the meantime by a group of barons to take the Hungarian throne. The city of Pozsony constantly supported Elisabeth and her court in realizing their plans. The reports of the queen’s envoys and the account book of Pozsony help us reconstruct the exact course of events leading up to the queen’s arrival in her beloved city.
