Prince Louis became a successful businessman, with a number of financial interests in Africa. In 1951, the prince sent a memorial wreath bearing the Napoleonic 'N' insignia to the funeral of William, German Crown Prince, son of the deposed Wilhelm II, German Emperor. This was seen as an ironic gesture by royalists at the time, given the fact that it was the German House of Hohenzollern that had defeated and dethroned Louis Napoleon's own imperial house during the Franco-Prussian War in 1870.
