Maria Theresa, Holy Roman Empress, Queen of Bohemia and Hungary, Archduchess of Austria, was (reigning) Archduchess of Austria and Queen of Hungary and Bohemia. Maria Theresa was the oldest daughter of Emperor Charles VI, who promulgated the Pragmatic Sanction to allow her to succeed to the Habsburg monarchy, and Elisabeth Christine of Brunswick-Wolfenbüttel.
