The statue of Maria Theresa by sculptor Kaspar von Zumbusch in front of the Art History Museum (Kunsthistorisches Museum) She is shown surrounded by her 4 generals on horseback and other notable persons during her reign. In the center is the composer Mozart shown as a boy. Maria Theresa ruled Austria from 1740-1780. Due to her father, the emperor Charles VI, lacking a male heir, she ascended the Habsburg throne and triggered the War of the Austrian Succession. She held every Habsburg imperial title except one, including the Queen of Bohemia, Queen of Hungary, and Archduchess of Austria. Being female, she was ineligible for the crown of the Holy Roman Empire. Her husband Francis, the Duke of Lorraine, and later her son Joseph II, held that title. For this reason, the Habsburg Monarchy was also known from this time as the House of Habsburg-Lorraine.
