About Louis, Prince Napoleon

Louis, Prince Napoléon, (Louis Jérôme Victor Emmanuel Léopold Marie; 23 January 1914 – 3 May 1997) as Napoleon VI was the claimant to the Imperial throne of France of the Bonaparte dynasty from 1926 until his death.

Early life

He was born in Brussels, Belgium, due to the law which then banned heirs of the former French ruling dynasties from residing in France. He was the son of Victor, Prince Napoléon and his wife Princess Clémentine of Belgium, daughter of King Leopold II of the Belgians and Archduchess Marie Henriette of Austria. Leopold II's mother, Princess Louise-Marie of Orléans, was the eldest daughter of King Louis Philippe I, ruler of France during the July Monarchy.

As a child, Prince Louis spent some time in England where he stayed with Empress Eugénie, the widow of Napoleon III. He was educated in Leuven in Belgium and Lausanne in Switzerland. His father died on 3 May 1926, and so Prince Louis succeeded as the Bonapartist claimant to the French throne at the age of 12 with his mother acting as regent until he came of age.

World War II and later life

On the outbreak of World War II Prince Louis wrote to the French prime minister, Édouard Daladier, offering to serve in the French Army. His offer was refused so he assumed the nom de guerre of Louis Blanchard and joined the French Foreign Legion, seeing action in North Africa before being demobilised in 1941 following the Armistice. He then joined the French Resistance and was arrested by the Germans after attempting to cross the Pyrenees to get to London to join Free French leader Charles de Gaulle. Following his arrest he spent time in various prisons including Fresnes. Following his release, he joined the French Resistance group Organisation de Résistance dans l'Armee under the name Louis Monnier. Another member of the Charles Martel Brigade to which he belonged was his cousin, Prince Joachim Murat who was killed in July 1944. Prince Louis himself narrowly escaped death a month later when, on 28 August, he was badly wounded as part of a seven man patrol which came under attack: he alone survived. Following his recovery he joined the Alpine Division and was later decorated for bravery.

After the war, he lived in Switzerland and, illegally, in Paris until 1950 when the law of banishment against the heads of France's former ruling dynasties was repealed.

In his professional life, 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 which had defeated and dethroned Louis Napoleon's own imperial house during the Franco-Prussian War in 1870.

Following Prince Louis' death in Prangins, Switzerland, his will designated his grandson, Prince Jean-Christophe Napoléon, as his successor, thereby bypassing his elder son, Prince Charles Napoléon.
