聖イシュトヴァーンの王冠
Louis the Great died on 10 September 1382. Cardinal Demetrius, Archbishop of Esztergom, crowned Mary "king" with the Holy Crown of Hungary in Székesfehérvár on 17September, a day after her father's burial. Mary's title and her rapid coronation in the absence of her fiancé, Sigismund, show that her mother and her mother's supporters wanted to emphasize Mary's role as monarch and to postpone or even hinder Sigismund's coronation.
