French Empire

Napoleon I on his Imperial Throne, by Jean Auguste Dominique Ingres, 1806

Napoleon faced royalist and Jacobin plots as France's ruler, including the Conspiration des poignards (Dagger plot) in October 1800 and the Plot of the Rue Saint-Nicaise (also known as the infernal machine) two months later.In January 1804, his police uncovered an assassination plot against him which involved Moreau and which was ostensibly sponsored by the Bourbon former rulers of France. On the advice of Talleyrand, Napoleon ordered the kidnapping of Louis Antoine, Duke of Enghien, in violation of neighbouring Baden's sovereignty. After a secret trial the Duke was executed, even though he had not been involved in the plot.
Napoleon used the plot to justify the re-creation of a hereditary monarchy in France, with himself as emperor, as a Bourbon restoration would be more difficult if the Bonapartist succession was entrenched in the constitution. Napoleon crowned himself Emperor Napoleon I on 2 December 1804 at Notre Dame de Paris and then crowned Joséphine Empress. The story that he seized the crown out of the hands of Pope Pius VII during the ceremony to avoid his subjugation to the authority of the pontiff is apocryphal; the coronation procedure had been agreed in advance. At Milan Cathedral on 26 May 1805, Napoleon was crowned King of Italy with the Iron Crown of Lombardy. He created eighteen Marshals of the Empire from amongst his top generals, to secure the allegiance of the army. Ludwig van Beethoven, a long-time admirer, was disappointed at this turn towards imperialism and scratched his dedication to Napoleon from his 3rd Symphony.
