Louis Philippe II, Duke of Orleans (1747 - 1793). Louis Philippe Joseph d'Orléans, most commonly known as Philippe, was born at the Château de Saint-Cloud. He received the title of Duke of Montpensier at birth, then that of Duke of Chartres at the death of his grandfather, Louis d'Orléans, in 1752. At the death of his father, Louis Philippe d'Orléans, in 1785, he inherited the title of Duke of Orléans and also became the Premier prince du sang, title attributed to the Prince of the Blood closest to the throne after the Sons and Grandsons of France. He was addressed as Son Altesse Sérénissime. In 1792, during the French Revolution, he changed his name to Philippe Égalité. Louis Philippe d'Orléans was a cousin of Louis XVI and one of the wealthiest men in France. He actively supported the Revolution of 1789, and was a strong advocate for the elimination of the present absolute monarchy in favor of a constitutional monarchy. He voted for the death of king Louis XVI; however, he was himself guillotined in November 1793 during the Reign of Terror. His son Louis Philippe d'Orléans became King of the French after the July Revolution of 1830. After him, the term Orléanist came to be attached to the movement in France that favored a constitutional monarchy. Louis Philippe Joseph d'Orléans was the son of Louis Philippe d'Orléans, Duke of Chartres, and Louise Henriette de Bourbon. Philippe was a member of the House of Orléans, a cadet branch of the French royal family. His mother came from the House of Bourbon-Condé. Philippe was born at the Château de Saint Cloud, one of the residences of the Duke of Orléans, five kilometers west of Paris. His older sister, born in 1745, died when she was six months old. His younger sister, Bathilde d'Orléans, was born in 1750. Philippe's first title, given to him at birth, was that of the Duke of Montpensier. After his grandfather's death in 1752, Philippe inherited the title of Duke of Chartres. After his father's death in 1785, Philippe became the Duke of Orléans, head of the House of Orléans, one of the wealthiest noble families in France. At his father's death, Philippe became the Premier Prince du Sang, First Prince of the Blood, which put him in line for the succession to the throne immediately after the comte d'Artois, the youngest brother of Louis XVI. On 6 June 1769, Louis Philippe married Louise Marie Adélaide de Bourbon at the chapel of the Palace of Versailles. She was the daughter of his cousin, Louis Jean Marie de Bourbon, Duke of Penthièvre, one of the richest men in France. Since it was certain that his wife would become the richest woman in France upon the death of her father, Louis Philippe was able to play a political role in court equal to that of his great-grandfather Philippe II, Duke of Orléans, who had been the Regent of France during the minority of Louis XV. Louise Marie Adélaide brought to the already wealthy House of Orléans a considerable dowry of six million livres, an annual income of 240,000 livres, as well as lands, titles, residences and furniture.Unlike her husband, the Duchess of Orléans did not support the Revolution. She was a devout Catholic who supported keeping the monarchy in France, as well as following the orders of Pope Pius VI. This was the causes of one of the rifts of the couple, as their first son, the future King of the French, followed his father's footsteps and joined the Jacobin faction. During the first few months of their marriage, the couple appeared devoted to each other, but the Duke went back to the life of libertinage he had led before his marriage. The Duke was a well-known womanizer and, like several of his ancestors, such as Louis XIV and Philippe II, Duke of Orléans, had several illegitimate children. During the summer of 1772, the Duke began his secret liaison with one of his wife's ladies-in-waiting, Stéphanie Félicité Ducrest de St-Albin, comtesse de Genlis, the niece of Madame de Montesson, the morganatic wife of Philippe's father. Passionate at first, the liaison cooled within a few months and, by the spring of 1773, was reported to be dead. After the romantic affair was over, Madame de Genlis remained in the service of Marie-Adélaide at the Palais-Royal, a trusted friend to both the Duke and the Duchess. They both appreciated her intelligence and, in July 1779, she became the governess of the couple's twin daughters. One of his most known lovers was Grace Elliot. It was alleged that Lady Edward FitzGerald, born Stephanie Caroline Anne Syms, also known as Pamela, was a natural daughter of the Duke and the Countess of Genlis.
