Maria Letizia Bonaparte (Marie Laetitia Eugénie Catherine Adélaïde; 20 November 1866 – 25 October 1926) was one of three children born to Prince Napoléon and his wife Princess Maria Clotilde of Savoy. In 1888 she married Prince Amadeo, Duke of Aosta, the former king of Spain and her uncle. Maria Letizia became the Duchess of Aosta, as Amadeus was known before and after his kingship as Duke of Aosta. Their marriage was instrumental in almost reviving French hopes of reinstating the Bonaparte dynasty into a position of power, as seen in the days of Napoleon III.
