Marie Louise's father was born February 12, 1768, a year and a half earlier than the Emperor Napoleon. He was the grandson of the great Empress Marie Thérèse, and son of the Emperor Leopold II., who was the brother of the Queen of France, Marie Antoinette, and whom he succeeded March 1, 1792; his mother was a Spanish princess, a daughter of Charles III. of Spain. He had four wives. He was an excellent husband, but his family affections were so strong that he could not remain a widower. In 1788 he married his first wife, Princess Elizabeth Wilhelmina Louisa of Wurtemberg, who died February 17, 1790, in giving birth to a daughter who lived but six months. The same year he married by proxy at Naples, August 15, and September 19 in person at Vienna, the young Neapolitan princess Marie Thérèse, daughter of Ferdinand IV. and of Marie Caroline, who ruled over the Two Sicilies. The young princess, who was born June 6, 1772, was then eighteen years old. She was kind, virtuous, and well educated, and her influence at the court of Vienna was most excellent. Her mother, who during her reign of thirty-six years endured many trials and exhibited great qualities as well as great faults, was a remarkable woman. Marie Caroline, the Queen of Naples, was energetic to excess, courageous to the point of heroism; she believed that severity and sometimes even cruelty was demanded of a sovereign; her religion amounted to superstition, her love of authority to despotism; she alternated between passionate devotion to pleasure and earnest zeal for her duty; she was ardent in her affections and implacable in resentment, intense in her joys and in her sorrows; she was often an unwise queen, but as a mother she was beyond reproach. Like the matrons of antiquity and her illustrious mother, the Empress Marie Thérèse, she was proud of her large family; she had no fewer than seventeen children, and political cares never prevented her actively and intelligently caring for their moral and physical welfare. If she had not the happiness of seeing them all grow up, those who survived were yet the constant object of her tender solicitude. She took a prominent part in the education of her two sons, the Duke of Calabria and the Prince of Salerno, and still more in that of her five daughters: Marie Thérèse, the wife of the Emperor Francis II.; Marie Louise, who married the Archduke Ferdinand, Grand Duke of Tuscany; Marie Christine, wife of Charles Felix, Duke of Genoa, later King of Sardinia; Marie Amélie, Duchess of Orleans, then Queen of France; Marie Antoinette, first wife of the Prince of Asturias, later Ferdinand VII., King of Spain.
