His nephew, Philippe d’Orléans, the regent for the five-year-old King Louis XV, moved the royal residence and government back to Paris, where it remained for seven years. The king lived in the Tuileries Palace, while the regent lived in his family's luxurious Parisian residence, the Palais-Royal (the former Palais-Cardinal of Cardinal Richelieu). The regent devoted his attention to theater, opera, costume balls, and the courtesans of Paris.
