Maria Theresa Walburga Amalia Christina was the only female ruler of the Habsburg dominions, ruling from 1740 until her death. She was the sovereign of Austria, Hungary, Croatia, Bohemia, Transylvania, Mantua, Milan, Lodomeria and Galicia, the Austrian Netherlands, and Parma. By marriage, she was Duchess of Lorraine, Grand Duchess of Tuscany and Holy Roman Empress.
Maria Theresa started her 40-year reign when her father, Emperor Charles VI, died in October 1740. Charles VI paved the way for her accession with the Pragmatic Sanction of 1713 and spent his entire reign securing it. He neglected the advice of Prince Eugene of Savoy, who believed that a strong military and a rich treasury were more important than mere signatures.
