Archduchess Maria Anna (known as "Marianna") was born on 6 October 1738 at the Hofburg Palace in Vienna, the center of the vastly powerful Habsburg Monarchy. As the second but eldest surviving daughter of Maria Theresa, Queen of Hungary and Bohemia, and Francis I, Holy Roman Emperor, she was heiress presumptive of the hereditary lands of the Austrian Habsburgs between 1740 and 1741, until her younger brother Joseph (later to be the Holy Roman Emperor Joseph II) was born.
