May 30, 1574 – Death of King Charles IX of France at the Château de Vincennes; buried at the Basilica of Saint-Denis near Paris, France
Charles became King of France at the age of ten. The horrific St. Bartholomew’s Day Massacre, in which 5,000 to 30,000 French Protestants were killed called Huguenots, occurred during his reign. Although Charles publicly approved of the results of the St. Bartholomew Day’s Massacre, it left him with a psychological trauma that lasted for the remaining two years of his life. He became increasingly depressed and his already weak constitution could no longer resist the tuberculosis that ravaged his body and he died at the age of 23.

May 30, 1653 – Birth of Archduchess Claudia Felicitas of Austria, Holy Roman Empress, the second of the three wives and the second cousin of Leopold I, Holy Roman Emperor, in Innsbruck, then in the County of Tyrol, now in Austria
Claudia Felicitas married her second cousin the future Leopold I, Holy Roman Emperor. Claudia Felicitas and Leopold I combined for a gene pool that was also problematic. They were second cousins four times over. Leopold’s parents and Claudia Felicitas’ parents were all double first cousins with each other. All four had the same pair of grandparents Karl II, Archduke of Austria and Maria Anna of Bavaria. Perhaps that is why their two daughters died in infancy. Six months after giving birth to her last daughter, 22-year-old Claudia Felicitas died from tuberculosis on April 8, 1676, less than two-and-a-half years after her marriage.

His wife Sarah was Queen Anne’s Mistress of the Robes and confidante. Fifteen-year-old Arabella was sent to court to be a Maid of Honor to the Duchess of York.

May 30, 1826 – Birth of Arcadie Claret, mistress of Leopold I, King of the Belgians in Brussels, Belgium
Arcadie Claret was the mistress of Leopold I, King of the Belgians, the uncle of both Queen Victoria and Prince Albert, from around 1842 until he died in 1865. Because their relationship became publicly known and widely discussed in the press, Leopold arranged a marriage between Arcadie and Ferdinand Meyer, his Master of the Stable and friend. This marriage of convenience provided some relief from the intense speculation about Arcadie and her relationship with Leopold. Arcadie and Leopold had two sons together although both were registered as her husband’s children and given the surname Meyer.

Full name: Leopold Julius Bernhard Adalbert Otto Karl Gustav
During Leopold IV’s reign, there was much economic and cultural advancement. The major building projects provided much-needed employment for the people of Lippe. Christ Church in Detmold was built in 1908 to accommodate the growing Protestant community which had outgrown the small Church of the Redeemer. It is the burial site of Leopold IV, his two wives, and most of their children. Leopold was the last reigning Prince of Lippe, abdicating on November 12, 1918.  He negotiated a treaty with the new government allowing his family to remain in Lippe.

Vilhelmine Marie’s first marriage to the future King Frederik VII of Denmark was unhappy and the couple divorced. She made a second marriage to Karl, Duke of Schleswig-Holstein-Sonderburg-Glücksburg, elder brother of Prince Christian of Schleswig-Holstein-Sonderburg-Glücksburg, the future King Christian IX of Denmark who would succeed King Frederik VII, Vilhelmine Marie’s thrice-married but childless first husband. Vilhelmine Marie’s second marriage was a happy one but it was childless. In 1864, after the Second Schleswig War, which Denmark lost, Karl’s duchy was annexed by Prussia and Karl lost his ducal title. Vilhelmine Marie and Karl were able to live at the family ancestral home Schloss Glücksburg and Karl died there in 1878. Vilhelmine Marie’s charitable work made her popular in Glücksburg. She was sad about Denmark’s loss of the Schleswig-Holstein duchies but the new Danish dynasty founded by her brother-in-law King Christian IX gave her much joy. Eventually, she became more and more isolated as her hearing loss made it difficult to communicate. Vilhelmine Marie survived her husband Karl for thirteen years, dying on May 30, 1891, at the age of 83
