Maria Theresa (1717-1780) was once the most powerful woman in Europe. At the age of twenty-three, she ascended to the throne of the Habsburg Empire, a far-flung realm composed of diverse ethnicities and languages, beset on all sides by enemies and rivals. Barbara Stollberg-Rilinger provides the definitive biography of Maria Theresa, situating this exceptional empress within her time while dispelling the myths surrounding her. A panoramic work of scholarship that brings Europe's age of empire spectacularly to life, Maria Theresa paints an unforgettable portrait of the uncompromising yet singularly charismatic woman who left her enduring mark on the era in which she lived and reigned.
