During the reign of Napoléon Bonaparte as First Consul and then Emperor, music in Paris was used to celebrate his victories and glory. Napoleon installed his brother Lucien as chief censor in 1800, and all musical and theater works were examined by the police before being performed. The former Academy of Music became the "Académie impériale de musique". The official composer of Napoleon's regime was Jean-François Lesueur, who wrote a heroic opera, "Ossian, ou Les bardes" to glorify Napoleon. It was performed more than a hundred times in Paris before Napoleon's fall. Lesueur also wrote a special march for the coronation of Napoleon as Emperor at Notre-Dame, and directed the solemn mass, "Te Deum" and other music performed at the coronation. Lesueur wrote new opera "Le Triomphe de Trajan", to celebrate Napoleon's victories at Jena, Friedland and Eylau. The opera had spectacular staging, with parades of soldiers and cavalry on stage. Lesueur continued his musical career after Napoleon's fall, as a professor of composition at the Conservatory; his future students included Hector Berlioz and Charles Gounod.
