On the death of his brother Edward III, Duke of Bar at the Battle of Agincourt in 1415, Louis inherited the dukedom and successfully defended his claim to it against that of his brother-in-law Adolphe, Duke of Juliers and of Berg, who felt that, as a clergyman, Louis was not suited to inherit the dukedom and its revenues.
In the next year he appointed his infant nephew, Prince Napoleon Louis Bonaparte (1804–1831), the elder son of Napoleon's brother Louis Bonaparte, King of Holland, Grand Duke of Berg; French bureaucrats under Pierre Louis Roederer administered the territory in his name.
