About HSH Princess Charlotte de Monaco, Duchess of Valentinois

Charlotte wasn’t born a Princess and at the time of her birth nobody probably even imagined the role she would go on to play. She was born as Charlotte Louise Juliette Louvet on 30 September 1898 as the illegitimate daughter of Marie Juliette Louvet, a cabaret singer and Louis Grimaldi, who was at the time the Hereditary Prince of Monaco and Duke of Valentinois. He had wanted to marry Marie and legitimise Charlotte, but his father was having none of that. Charlotte attended a boarding school in France. When the First World War broke out, Louis was swift in moving his daughter out of France and into the palace in Monaco.

Louis succeeded his father as reigning Prince of Monaco in 1922 but even before that, they tried to prevent a succession crisis. Louis was unmarried and had no legitimate children or siblings. On 15 May 1911, a law was passed which recognised Charlotte as Louis’ daughter and she was declared to be a dynastic member of the family. This law was later held to be invalid but an ordinance was passed on 30 October 1918 adopting her into the dynasty instead. She was officially adopted on 16 May 1919 and her grandfather bestowed the Duchess of Valentinois title on her. She became the Hereditary Princess of Monaco when her grandfather died in 1922.
