At Paris the fickle multitude soon forgot the son of the Emperor. In 1820 the capital saluted the birth of the Duke of Bordeaux as it had saluted that of the King of Rome. A close relationship united the two children who represented two such distinct parties; their mothers were first-cousins on both their fathers' and their mothers' side. The Duchess of Berry, mother of the Duke of Bordeaux, was the daughter of the King of Naples, Francis I., son of King Ferdinand IV. and Queen Marie Caroline; and her mother was the Princess Marie Clementine, daughter of the Emperor Leopold II. The Emperor Francis, father of the Empress Marie Louise, was himself the son of Leopold II.; his wife was Princess Marie Thérèse of Naples, daughter of Queen Marie Caroline and aunt of the Duchess of Berry. The King of Rome and the Duke of Bordeaux were thus in two ways second-cousins. July 22, 1821, at Schoenbrunn, in the same room where, eleven years later, in the same month and on the same day of the month, he was to breathe his last, the child who had been the King of Rome learned that his father was dead. This news plunged him into deep grief. He had been forbidden the name of Bonaparte or Napoleon, but he was allowed to weep. The Duke of Reichstadt and his household were allowed to wear mourning for the exile of Saint Helena. In justice to the Emperor Francis it must be said that he showed great affection for his grandson, whom he kept always near him, in his chamber and in his study, and that he hid from him neither Napoleon's misfortunes nor his successes. "I desire," he told Prince Metternich, "that the Duke of Reichstadt shall respect his father's memory, that he shall take example from his firm qualities and learn to recognize his faults, in order to shun them and be on his guard against their influence. Speak to the prince about his father as you should like to be spoken about to your own son. Do not hide anything from him, but teach him to honor his father's memory." Military drill, manoeuvres, strategy, the study of great generals, especially of Napoleon, formed the young prince's favorite occupations.
