let her stay after her husband's departure. This was done on the condition that she stay away from the court and live at the Val-de-Grâce convent of her childhood. As a result of manipulations by her mother and brother, she was never allowed to be received by the queen, Maria Leszczyńska. It was always maintained that such a public event would cause too much damage by exposing her incognito status. Her husband returned in May 1736. Much to the annoyance of her family, Charlotte Aglaé and her husband remained in Paris. A dramatic argument followed in which Charlotte Aglaé and her sister, the Dowager Queen of Spain, squabbled over a question of etiquette. When her family took the Dowager Queen's side completely, Charlotte Aglaé became even further isolated. Sometime after, her husband had to go to Hungary. Charlotte Aglaé persuaded Cardinal Fleury to convince the young king to once again let her stay in Paris and not depart with her husband. The cardinal also convinced her family into accepting her continued presence in France. Upon the death of her father-in-law in 1737, her husband became Francesco III, reigning Duke of Modena. Despite Charlotte Aglaé's new rank as the wife of a Sovereign Prince, she did not receive any better treatment in France. Family relations were further worsened when Charlotte Aglaé and her brother engaged in a trivial lawsuit regarding some family property. In June 1739, she reluctantly returned to Modena. In an attempt to make the place fashionable, she promoted the arts. She introduced a French-style theatre to Modena, which was a great success. She also added a corps de ballet to the city in which she took great pride. Her husband also made several additions to the Ducal Palace of Modena, including a large hall which was an exact replica of one at the Tuileries Palace. During their marriage, her husband amassed one of the finest portrait collections in Italy. In 1741, her eldest son, Ercole, the ducal heir, married Maria Teresa Cybo-Malaspina (1725–1790). She was the daughter of Alderano Cibo-Malsapina, Duke of Massa and his wife Ricciardia Gonzaga di Novellara. Maria Teresa had become Duchess of Massa and Cararra in her own right in 1731 upon the death of her father. The young couple would later have two children who survived into adulthood. In 1743, due to the War of the Austrian Succession, Charlotte Aglaé was forced to
