Adélaïde of France, born on March twenty-third, seventeen thirty-two, was a prominent French princess and the sixth child of King Louis XV and Queen Marie Leszczyńska. As a legitimate daughter of the King, she held the title of fille de France and was initially known as Madame Quatrième, a designation she maintained until the passing of her elder sister, Marie Louise, in seventeen thirty-three. Following this, she became Madame Troisième, and from seventeen thirty-seven to seventeen fifty-five, she was referred to as Madame Adélaïde.
In seventeen fifty-five, her title changed to simply Madame until seventeen fifty-nine, after which she reclaimed the name Madame Adélaïde, which she held until her death. Alongside her sister Sophie, Adélaïde was granted the Duchy of Louvois in seventeen seventy-seven, a title bestowed upon them by their nephew, Louis XVI, allowing them to possess it in their own right.
During the reign of her nephew, Adélaïde emerged as a leading figure of the extreme conservative faction at court, famously opposing Marie Antoinette, whom she derogatorily referred to as 'the Austrian.' The onset of the French Revolution forced Adélaïde and her sister Victoire to flee their homeland, ultimately settling in Rome. However, as the French Republic invaded the Italian Peninsula in seventeen ninety-six, the sisters relocated to Naples.
In seventeen ninety-nine, with France's conquest of Naples, the sisters found themselves in Trieste, where they both passed away, Adélaïde in seventeen ninety-nine and Victoire in eighteen hundred. Notably, Adélaïde was the last surviving child of Louis XV, marking the end of an era for the royal family.
