Reasons for the failure of the French Empire during the reign of Napoleon.

At the beginning of the 19th century, France was the most powerful power in Europe. Thanks to Napoleon, she was able to reach unprecedented heights. But still, through the fault of the same Napoleon, it fell into decay. Driven by his ambitions, Napoleon made a major campaign against Russia in 1812, but suffered a catastrophic defeat and lost his army. This was the reason that many European countries, conquered by Napoleons, in 1813 opposed him. Again Napoleon was severely defeated at the Battle of Leipzig. Finally, Napoleon was defeated in 1815.
