Ferdinand I., King of the Two Sicilies

Ferdinand I., King of the Two Sicilies (Ferdinand V. of Naples) (1751-1825), was the son of Charles III. of Spain. When the father became King of Spain, the son succeeded him as King of Naples. His marriage with a daughter of Maria Theresa led to a close understanding with the' .Cabinets of Austria and Great Britain, and an opposition to the French after the Revolution, which led to three different humiliations of Ferdinand by the French. In 1814 the Congress of Vienna confirmed his title as King of the Two Sicilies, and in 1815 he was again established at Naples upon the flight of Murat, whom Napoleon had put upon the Neapolitan throne. In 1820 his disregard of an oath to observe a new constitution led to his further flight, but Austrian aid reestablished him as a despot in 1821.
