 Contrary to all expectations , a significant amount of support for the young Queen came from Hungary . Her coronation as queen of Hungary took place in St. Martin 's Cathedral , Pressburg on 25 June 1741 after she had spent months honing the equestrian skills necessary for the ceremony and negotiating with the Diet . To appease those who considered her sex to be the most serious obstacle , Maria Theresa assumed masculine titles . Thus , in nomenclature , Maria Theresa was archduke and king ; normally , however , she was styled as queen . No 18th @-@ century commentary saw this crossing of gendered titles as inappropriate or impossible .
