Napoleon was a genius in the history of the world. He was a hero for a lifetime, but he was by no means a reckless warrior. Napoleon not only created an era, but also achieved the glorious art of that era. His name is closely connected with the Arc de Triomphe, Notre Dame, the Louvre, etc. In the Louvre, Napoleon's glory lasted for 12 years until his defeat at the Battle of Waterloo. During Napoleon's reign, in addition to continuous expansion and domination of Europe, he also ordered a large-scale expansion of the Louvre and moved the best works of art from other European countries into the Louvre, enriching the Louvre collection in an unprecedented way. In May 1792, the French National Assembly announced that the Louvre belonged to the public and became a public museum. In 1794, the Art Museum of Art was officially opened to the public and became a comprehensive public museum with a collection of 400,000 art treasures from around the world.
