Duke of Navarre

It was created, as Duchess of Navarre (French: duchesse de Navarre), by letters patent of 9 April 1810 for Empress Joséphine, following her divorce from Napoleon earlier that year.

Upon Maximilian's death in 1852, during the Second French Empire, his eldest son Nicholas was prevented from succeeding.

Through his mother, Grand Duchess Maria Nikolaevna of Russia, he was a member of a foreign royal family and thus unable to take the required oath to establish succession to the majorat.
