ask for permission to return to Paris with her eldest daughter, Maria Teresa. This request was at first ignored but help came from her old lover, the Duke of Richelieu, who used his influence over Louis XV's current mistress, the Duchess of Châteauroux, to gain the necessary approval. When she arrived in Paris, she was greeted with all of the honours owed her due to her rank. She was now a stout, red-faced woman, looking rather like her father. She lived on the Rue de Grenelle in the Faubourg Saint-Germain and became a friend of the Duchess of Châteauroux. Upon the death of Duchess of Châteauroux, her influence dwindled for a time. In 1744, however, she was able to secure for her daughter, Princess Maria Teresa of Modena, a marriage to the Duke of Penthièvre, the richest noble in France. Louis Jean Marie de Bourbon, was Charlotte Aglaé's younger first cousin and was the heir to the vastly wealthy House of Bourbon-Penthièvre. The couple married happily in 1744 and had two surviving children. Their eldest child, the Prince de Lamballe, married Maria Teresa Luigia di Savoia, the future friend of Marie Antoinette, in 1767. Their second child, Louise Marie Adélaïde de Bourbon, married the Duke of Chartres, (known as Philippe Égalité during the French Revolution of 1789) and later became the mother of Louis-Philippe I, King of the French. At Maria Teresa's death in 1754, Monsieur de Penthièvre travelled to Italy where another of Charlotte Aglaé's daughters was proposed, the Princess Matilde.

This advantageous marriage by her daughter allowed Charlotte Aglaé to have some say in French politics for a short period. Things began to change when Madame de Pompadour was presented at court in 1745. After the Treaty of Aix-la-Chapelle was signed in 1748, Charlotte Aglaé did not return to Modena. By 1754, it seemed that she had lost her flair at Versailles. Despite this, she did manage to secure a French marriage for her fourth daughter, Princess Maria Fortunata. Maria Fortunata, like her older sister, married one of her mother's cousins, Louis François II de Bourbon, Prince of Conti. He was the last prince de Conti. The marriage proved very unhappy, to the point where the groom did not want to live any longer with his wife. Charlotte Aglaé finally returned to Modena in 1759. There, she
