Camillo Borghese, 6th Prince of Sulmona

Don Camillo Filippo Ludovico Borghese, Prince of Sulmona and of Rossano, Duke and Prince of Guastalla, was a member of the Borghese family and was best known for being a brother-in-law of Napoleon. In 1803, Borghese married Napoleon's younger sister, Pauline Bonaparte, which led to Napoleon granting him multiple titles. After Napoleon was defeated, Borghese fled from France and left his wife behind. Consequently, he was stripped of the titles granted to him by Napoleon, although he retained his family's ancestral titles. While in Florence, he died at the age of 56, and the cause of death is unknown.
