路易·波拿巴
In 1809, one year after Murat's promotion from Grand Duke of Berg to King of Naples, Napoleon's young nephew, Prince Napoleon Louis Bonaparte (1804–1831, elder son of Napoleon's brother Louis Bonaparte, King of Holland) became the Grand Duke of Berg; French bureaucrats administered the territory in the name of the child. The Grand Duchy's short existence came to an end with Napoleon's defeat in 1813 and the peace settlements that followed.
